Classpath

Hi all,

I'm new to WS and would like to deploy an application I'm developing though this technology.
When I run the jar file all works just fine, but launching it through web start gives me an classnotexception, although all the necessary jars are being dl'ed..

Here's my JNLP file:

<?xml version="1.0" encoding="utf-8"?>
<jnlp
  spec="1.0+"
  codebase="http://myServer/aqt">
  <information>
    <title>Advanced Query Tool</title>    
    <description>Advanced Query Tool</description>    
  </information>
<offline-allowed/>
  <security>
      <all-permissions/>
  </security>
 
  <resources>
      <j2se version="1.4"/>
      <jar href="aqt.jar"/>
      <jar href="lib/FrameWork.jar"/>
      <jar href="lib/c3p0-0.8.4.5.jar"/>
      <jar href="lib/cglib-full-2.0.2.jar"/>
      <jar href="lib/commons-logging-1.0.4.jar"/>
      <jar href="lib/commons-collections-2.1.1.jar"/>
      <jar href="lib/dom4j-1.4.jar"/>
      <jar href="lib/hibernate2.jar"/>
      <jar href="lib/jdbcappender.jar"/>
      <jar href="lib/jta.jar"/>
      <jar href="lib/msbase.jar"/>
      <jar href="lib/mssqlserver.jar"/>
      <jar href="lib/msutil.jar"/>
      <jar href="lib/jtds-0.9.jar"/>
      <jar href="lib/log4j.jar"/>
      <jar href="lib/odmg-3.0.jar"/>
      <jar href="lib/poi-2.5.1-final-20040804.jar"/>
      <jar href="aqt_dao.jar"/>
  </resources>
  <application-desc main-class="com.lmsintl.its.aqt.AQTool">
  </application-desc>
</jnlp>

And this is what my manifest looks like (of aqt.jar)

The resulting error looks like this:

java.lang.ExceptionInInitializerError

What am I doing wrong?

Hi

I had came across to a very similar problem like u r talking about

I resolved it eventually.

Here are the possible reason why u r code might not be working

1] Any how make sure that ur required JARs (with the latest version) have downloaded by Java Web Starts before launching the app at client end

2] Be sure u signed all JARs with the same key

3] Try to work-around the prob by placing all JARs in the same directory
and in manifest file just give the dot-separated (.) list of JARs so
that during execution of the app at client side it will look-for resources into the application dir (current directory)

I used JNPL for a integrating Java App to a PHP page where my web application is running

Hope this will help u a bit

Try using -i option while creating a jar
