ALSB install problems

On of our servers was throwing up an exception, while trying to start the Adminserver

The solution appears to be
"This usually happens if your machine is running low on space and WebLogic Server corrupted a file in the embedded LDAP.
To fix this problem you can delete the file /servers//data/ldap/config/replicas.prop or add 'replica.num=0' to replicas.prop file. "

Search jar files for class

Heres a handy little command for searching classes withen jar files (for example when searching all the jars in a war file)

find <dirs> -name '*.jar' -exec jar tvf {} \; > outputfile

THis will produce a list of all files in the jar files outputted to outputfile.

This script below will print out the filename of each jar, and each associated file within.

list=$(find /apps/bea -print | grep .jar)

for el in $list; do 

  printf "Searching in %s\n" "$el"; 

  case $el in 

    jar -tf $el | grep com.bea.console.utils.ConsoleRequestListener 

  ;; 

  esac 

done

Jaxb Multiple namespace definitions

I was mildly concerned about the number of namespace definitions that Jaxb was printing every time it marshaleld an Xml document.

I'm using Spring-ws with jaxb bindings. In my definition of the Spring Marshaller I declare the jaxb packages which this marshaller will marshall. Each of these is turned into a namespace definiton on the resulting xml doc.

<bean id="jaxb2Marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
    <property name="contextPath" value="com.company.package1:com.company.package2:com.company.package3:com.company.package4">
</property>
</bean>

Results in

<ns1:request ns1="http://www.company.com/Package1" ns2="http://www.company.com/Package2" ns3="http://www.company.com/Package3" ns4="http://www.company.com/Package4">
<ns1:data>text
    </ns1:data>
</request>

This was mildly irritating.

After a bit of searching I find its a 'performance feature' in Jaxb2

https://jaxb.dev.java.net/issues/show_bug.cgi?id=103

So they won't be fixing it.

The alternative from my point of view is to declare multiple marshallers, and use them where appropriate.

<bean id="jaxb2Marshaller1" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
  <property name="contextPath" value="com.company.package1">
</property>
</bean>
<bean id="jaxb2Marshaller2" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
  <property name="contextPath" value="com.company.package2">
</property>
</bean>
..etc..

Python gotcha

This Seemingly innocuous indentation error in python was annoying me.

Problem invoking WLST - Traceback (innermost last):
(no code object) at line 0
File "C:\apps\installWls.py", line 249
toDeploy = sys.argv[3]
^
SyntaxError: inconsistent dedent

Looking at my code (wlst code to auto deploy application into weblogic server), it was all indented correctly.

Well of course the computer was right. It wasn't indented correctly, but it was no obvious.

The issue was some copy and paste code I took from the internet.

It was indented using spaces, whereas I was using tabs.

Replacing the space indentation with tabs fixed the issue (but its not obvious uinless you set your editor to display non visible characters.

StackoverFlow using spring-ws on weblogic 9.2

We finally got our spring-ws application deployed.

Or so we thought. The next day when we arrived int he code was crashing, and the JMS queue was not been read....

The img to the right shows the non-heap memory growth. Something is not clearing.

Below is the stack trace we get

Edit

Two things to check that might help: (I have not been able to test this now, as I no longer work on this project or for this client.)

* Make sure that you haven't somehow configured a foreign JNDI or foreign JMS server that is self referencing.

* Make sure that you haven't specified a URL when there's no need to specify a URL. (Server side applications and configuration should never specify a URL for a resource unless the resource is in a different cluster. When a resource is located in the same cluster, JNDI lookups should simply be made directly in the cluster's JNDI name-space. The way to ensure that the lookup is direct is simply to use initial contexts that were created without an URL.)

Spring-ws and weblogic incompatibilities

I wrote about incompatible versions of spring before resulting in cryptic error messages.

Well my solution there wasn't the full picture, if you are running xml /web servicse on weblogic. (Though at least this time I recognised the error as incompatible jars)

I was getting various different non-intuitive errors when trying to run a spring-ws application on weblogic 9.2.1.

e.g.
<User defined listener org.springframework.web.context.ContextLoaderListener failed: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'webServiceTemplateProxy' defined in class path resource [com/meteor/provisioning/servicecategory/serviceBeansSpringConfig.xml]: Cannot resolve reference to bean 'webServiceTemplate' while setting bean property 'target'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean withname 'webServiceTemplate' defined in class path resource [com/meteor/provisioning/servicecategory/serviceBeansSpringConfig.xml]: Cannot resolve reference to bean 'messageFactory' while setting bean property 'messageFactory'; nested exception is org.springframework.beans.factory.BeanCreationException:

After a lot of effort and with help from various postings (namely here, and here ), I managed to track down the various xml jars I needed to override weblogics internal jars.

These include the following taken from my maven pom.xml file. (Note I can't guarantee that this is the full list, or that this list does not contain jars that are in fact not needed. All I can say is that this list worked for me). BTW some of these I had to manually install in my maven repository myself, as I couldn't find them on remote repositories.

The problem is with weblogic (various versions, 9.2, 9.2.1, 8.1, and I believe 10) and spring-ws. Weblogic comes with various xml libraries, most of which have been superseded by newer versions. Spring-ws requires some of these newer jars (e.g. saaj, and axiom), which in turn refer to newer versions of base xml libraries. Thus you have an incompatibility.


Also from Arjens post you need to update your weblogic.xml file, adding the following, to instruct weblogic to take the supplied files before already installed files int he weblogic system
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>

BTW I was only able to finally fix the problem by firstly deploying it on Tomcat.

The above example works much easier in Tomcat, since it doesn't have any conflicting xml libraries causing grief. By actually getting the application running in tomcat, I was able to (relatively) quickly find out which jars I needed.

Tomcat would throw a NoClassDefFound exception when it came across a jar it didn't have. This doesn't happen in weblogic since it has xml jars, just the wrong versions. Once I had the application running in tomcat, I knew I had found all the required jars. When I moved it back to weblgoic the problem was solved.

Note: unlike Ajens post, I required saaj1.3 in my WEB-INF/lib folder

Actually I wasn't quite there yet, (see next post), but I this had finally sorted out this problem

Failure executing javac

There's nothing quite so deflating as seeing a message like the following

[INFO] ------------------------------------------------------------------------
[ERROR] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Compilation failure
Failure executing javac, but could not parse the error:
An exception has occurred in the compiler (1.5.0_06). Please file a bug at the Java Developer Connection (http://java.sun.com/webapps/bugreport) after checking the Bug Parade for duplicates. Include your program and the following diagnostic in your report. Thank you.
com.sun.tools.javac.code.Symbol$CompletionFailure: file javax\xml\ws\WebServiceClient.class not found

You really begin to wonder if you're doing something very wrong.
Fortunately you're not, and there is a quick and easy workaround.
This it turns out is a bug with javac on windows

My quick solution. Compile using cygwin. (If you haven't got cygwin, simply download setup.exe, and install)

This worked fine. My details was using jdk 1.5.0_06 (the bug has been reported on 1.5.0_04, and seen on 1.6 as well), on windows xp building using maven 2.0.8. Running my maven script in a cygwin bash window worked fine.

spring versions

Beware of mixing tools with different Spring versions.

I was using spring ws 1.5.3, and getting the following error

java.lang.NoSuchMethodError: org.springframework.util.ResourceUtils.toURI(Ljava/net/URL;)Ljava/net/URI;
....

Problem is that I had spring 2.0.x on my path, but spring-ws requires spring 2.5.x

Once I updated to using spring 2.5.x the problem was solved.

Could be a nasty problem, since the error message could easily lead you on a wild goose chase

Why spring rocks in a nuthell

http://www.jroller.com/kdonald/entry/the_essence_of_spring

Injecting enums in Spring beans
Found this while searching for how to insert enums into Spring beans from the xml config file (basically you just put the enum value directly in the xml file, http://www.jroller.com/kdonald/entry/spring_hidden_gem_support_for)

PropertyPlaceholderConfigurer doesn't work with XmlBeanFactory

SImple gotcha.

I was using Spring and the PropertyPlaceholderConfigurer. This simply allows you to populate your spring config file with values from a properties file at runtime. For me the properties file is loaded from the classpath (using the classpath: prefix). this is then stored in a seperate config folder whihc is shared between all projects, thus allowing us to update the config file with needing to redploy the complete application again.

e.g.

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>jms.properties</value>
<ref bean="getNetworkServicePropertyFile" />
</list>
</property>
</bean>
<bean id="test" class="com.meteor.provisioning.Test">
<property name="jmsTemplate" value="${jms.receiveTimeout}" />
</bean>


I write a simple class to instantiate this from a Unit test.


public static BeanFactory getSpringContext() {
springConfigFile = System.getProperty("SpringConfig", springConfigFile);
if (_beanFactory == null) {
Resource resource = new ClassPathResource(springConfigFile);
//_beanFactory = new XmlBeanFactory(resource);
}
return _beanFactory;
}
public static Object getBean(String bean){
return getApplicationContext().getBean(bean);
}

and finally a test case

public class Test {
private String jmsTemplate;

public void setJmsTemplate(String jmsTemplate) {
this.jmsTemplate = jmsTemplate;
System.out.println("jmsTemplate = "+jmsTemplate);
}

@org.junit.Test
public void doTest(){
Utils.getBean("test");
}

}



It didn't work. The PropertyPlaceholderConfigurer, wasn't updating the internal spring file with values from the jms.properties. The jmsTemplate value was been returned as ${jms.receiveTimeout}

Turns out that only ApplicationContext files do the replacement. A quick update to

public static ApplicationContext getApplicationContext() {
springConfigFile = System.getProperty("SpringConfig", springConfigFile);
if (_beanFactory == null) {
_beanFactory = new ClassPathXmlApplicationContext(springConfigFile);
}
return _beanFactory;
}

fixed the problem. Thanks also to http://francisoud.blogspot.com/2007/06/spring-property-placeholder.html

N95

I recently got a N95 8GB.

A list of some of the shortcut keys

Code	Result
*#7370#	Reset the phone N.B. This deletes all content off your SiM including Spiderman 3 activation code. Be sure to back it up before hand
*#0000	Show phone firmware version.. e.g. my N95 8GB (aka N95-2) is V20.0.016 02-03-08 RM-320 Nokia N95 (01.01)
*#06#	IMEI number (International Mobile Equipment Identity)
3 Finger Restart Call (Grenn Key) + * + 3. THen hold down start key	Does a hard restart. can be used if phone won't start. (Also try removing battery for about 10 seconds. This worked for me)

Converting Video and Audio

This is going to be an ongoing article as I try and locate the best free tools for the job.
Good general reference site is Afterdawn, and their forums

Ok firsts.
Copy/ Backup DVD
DVDShrink is an invaluable tool for compressing and copying and backing up DVD's to a directory on your pc. It can copy full DVD, or you can remaster the contents and remove copyright protection notices/ menus/ trailers etc.
There's a handy guide on MrBass

Some newer DVD's have copy protection which DVDShrink can't handle, then DVDDecrypter can sometimes help. If you want to burn the result onto a backup DVD (instead of just storing it on your pc) you probably will still need to run DVDShrink on the ripped files to reduce them enough to fit on your backup DVD. (Unless your DVD burner can burn multi layer)

Burning Images
ISOBurn for buringn images

Video Converting formats
handbrake. This si a great tool (oringally only on Mac, but on Windows and Linux now), for ripping dvd's to mp4, or H264 formats. Doesn't convert formats from what I can see

Super tool for convert all sorts of types

Audio

Switch is a tool. I've just tried to convert 3 mp4's. Converted for 2 of them, didn't work on one.

• wav (PCM, ADPCM+, aLaw+, uLaw+, and others)
• mp3 (MPEG Layer 3)
• mp2+ (MPEG Layer 2)
• mpga+ (MPEG Audio)
• au
• aif/aiff
• gsm
• dct
• vox
• raw
• ogg
• flac
• amr
• wma*
• wmv*
• aac* (not aacPlus)
• m4a*
• mid+
• act/rcd/rec+ (newer version of format not supported)

Ruby Calnder plugin

New day new problem.

I installed a ruby on rails calendar plugin. Install worked fine. One of the install steps was to run

rake rdoc

This gave me the following problem
rake aborted!
no such file to load -- hoe
C:/dev/ruby/timesheet/vendor/plugins/calendar_helper/rakefile:4
(See full trace by running task with --trace)

Hoe it turns out is a simple ruby project for helping with rakefiles. To install Hoe

gem install hoe
(no need for sudo since I'm on windows)

Now rake rdoc gives me
rake aborted!
couldn't find HOME environment -- expanding `~/.hoerc'
C:/dev/ruby/timesheet/vendor/plugins/calendar_helper/rakefile:7:in `new'
(See full trace by running task with --trace)

This was because I was running on Windows not unix. Setting HOME environment helps this

set HOME=%HOMEPATH%

Now the problem is
rake aborted!
Don't know how to build task 'README'

This as it turns out was a problem with the rakefile. It referred to a non-existant file 'README ' in the plugin. There was however a Readme.txt file. Updating the Rakefile to refer to this finally fixed the issues.


require 'rubygems'
require 'rake'
require 'rake/rdoctask'
require 'hoe'
require './lib/calendar_helper.rb'

Hoe.new('calendar_helper', CalendarHelper::VERSION) do |p|
p.rubyforge_name = 'seattlerb'
p.author = 'Geoffrey Grosenbach'
p.email = 'boss AT topfunky.com'
p.summary = 'Generates a configurable, CSS-tagged HTML calendar.'
p.description = "A simple method to create an HTML calendar for a single month. Can be styled with CSS. Usable with Ruby on Rails."
p.url = "http://rubyforge.org/projects/seattlerb"
p.changes = p.paragraphs_of('History.txt', 0..1).join("\n\n")
p.clean_globs = ['test/output']
end

# desc "Test task (actually runs specs)"
# task "test" do
# system "spec --format specdoc --color spec/*_spec.rb"
# end

# -- Rails-specific --

desc 'Generate documentation for the calendar_helper plugin.'
Rake::RDocTask.new(:rdoc) do |rdoc|
rdoc.rdoc_dir = 'rdoc'
rdoc.title = 'CalendarHelper'
rdoc.options << '--line-numbers' << '--inline-source'
rdoc.rdoc_files.include('Readme.txt')

end

Ruby on Rails install headaches

Some problems installing ruby on rails that I thought I's document.

Firstly I followed the instructions on rubyonrails.org, downloading the altest version of ruby 1.86_25, downloading and installing ruby Gems. The the next step where you actually install rails is where the trouble started

C:\apps\ruby186.25\rubygems-0.9.5>gem install rails --include-dependencies
INFO: `gem install -y` is now default and will be removed
INFO: use --ignore-dependencies to install only the gems you list
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
Bad file descriptor - connect(2) (Errno::EBADF)


First problem was web proxys.

My laptop is used both in work and at home. In work I use a http proxy to access the web. At home I don't. The problem was I had set a system variable to set a http proxy variable. (http_proxy), but I was using my laptop at home.

To check if you use a http proxy from a DOS window type the following

echo %http_proxy%

If you get a response like
http://10.105.24.70:8080

then you have a http proxy set.

For me I had to remove the proxy. This is done by
set http_proxy=

For most people however I would imagine the problem is the opposite, you may need to set the http_proxy for your DOS window. To check if you need a http_proxy, goto your web browser

For IE
Tools/ Internet Options/ Connections/ LAN Settings/ Proxy Server
Note the url and port

For Firefox goto
Tools/ Options/ Advanced/ Network tab/ Settings (phew)
Note the url and port

You can set the proxy in the dos window simply by typing
set http_proxy=http://10.105.24.70:8080

With this done you should be able to retry the install

Next problem was

C:\apps\ruby186.25\rubygems-0.9.5>gem install rails --include-dependencies
INFO: `gem install -y` is now default and will be removed
INFO: use --ignore-dependencies to install only the gems you list
Bulk updating Gem source index for: http://gems.rubyforge.org
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
OpenURI::HTTPError: 404 Not Found reading http://gems.rubyforge.org/gems/activesupport-2.0.1.gem

THis was a temporary problem. I inserted the url into a browser and it worked. When I retried the command it also worked.

Oracle version

Ever wondered what version of oracle you were running?

Wonder no more

select name from v$database
select * from v$version

Working with saxon

Saxon didn't like the concatenation of the sequence. changing this to fn:string-join worked however.

declare namespace xf = "http://tempuri.org/xqueryTest/XQueryTransformations/csv/";

declare function xf:csv($aPIMessage1 as element(APIMessage))
    as xs:string {
     fn:string-join(
     for $line in $aPIMessage1/AuthResponse
     let $ct := concat($line/ClientTransactionReference, "," , $line/SystemReferenceNumber, ",", $line/ResponseInfo/ResponseCode , ",", $line/ResponseInfo/Result ,",", $line/ResponseInfo/Description , ",", $line/ApprovalInfo/ApprovalCode , ",", $line/ApprovalInfo/DateTime,  "
")
  return $ct,"")
};


declare variable $aPIMessage1 as element(APIMessage) external;

xf:csv(doc("./resp.xml")/APIMessage)

My first xquery; xml to csv

Got this working. Thought I'd post it. My first xquery. Parses an Xml response file (from a credit card authorisation system), and outputs some of the fields as a csv file. It was written using the BEA XQuery Mapper, which is a pluggin by BEA for eclipse 3.1.

Having an issue running it with Saxon at the moment

declare namespace xf = "http://tempuri.org/xqueryTest/XQueryTransformations/csv/";

declare function xf:csv($aPIMessage1 as element(APIMessage))
    as xs:string {
     concat(for $line in $aPIMessage1/AuthResponse
     let $ct := concat($line/ClientTransactionReference, "," , $line/SystemReferenceNumber, ",", $line/ResponseInfo/ResponseCode , ",", $line/ResponseInfo/Result ,",", $line/ResponseInfo/Description , ",", $line/ApprovalInfo/ApprovalCode , ",", $line/ApprovalInfo/DateTime,  "
")
  return $ct)
};



declare variable $aPIMessage1 as element(APIMessage) external;

xf:csv($aPIMessage1)

Ibatis problem

Document root element "sqlMap", must match DOCTYPE root "null"

This was the unhelpful exception I was gettign when I tried to run my ibatis/ spring prototype.

My ibatis sqlMap file looked ok

<sqlmapconfig>
<sqlmap resource="db/prov.xml">
</sqlmap>
<sqlmapconfig>javascript:void(0)
Publish Post

Had a search, you must add

<!DOCTYPE sqlMap PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-2.dtd">

to your sql map files

Note you must also have

<!DOCTYPE sqlMapConfig PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-config-2.dtd">

to your sql-map-config.xml file.
