Extentions not working

Question

Hi,
I am trying to make use of extention tag provided by webstart. I have included extention tag in the application's jnlp file and at the same time i have created the mentioned extention jnlp file. But when my application starts it downloads the resources mentioned using jar tag but does not download one mentioned thorugh extention tag. Since these jar files are required for application to start it aborts giving classnotfound error.
<code>
<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="$$codebase" href="test.jnlp">
     <information>
          <title>Sample</title>
          <vendor>ABC</vendor>
          <homepage href="../index.html"/>
          <description>Testing extentions</description>
          <description kind="short"></description>
          <offline-allowed/>
     </information>
     <security>
               <all-permissions/>
     </security>
     <resources>
          <j2se version="1.3"/>           
          <property name="SAMPLE" value="test"/>
          <jar href="Main.jar" version="1.0"/>
          <extention name="Sample EXT" href="ext.jnlp">
          </extention>
     </resources>
     <application-desc main-class="com.sample.Main">
     <argument>test</argument>
     </application-desc>
</jnlp>
</code>
Extention jnlp file is as follow
<code>
<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="1.0+" codebase="$$codebase" href="ext.jnlp">
     <information>
          <title>SampleEXT</title>
          <vendor>ABC</vendor>
     </information>
     <security>
               <all-permissions/>
     </security>
     <resources>
          <jar href="lib/UILibrary.jar" main="false" download="eager" part="UILib"/>
          <jar href="lib/jaxp.jar" main="false" download="lazy"/>
     </resources>
     <resources os="Windows">
     <nativelib href="lib/revera-native.jar" download="eager"/>
     </resources>
     <component-desc/>
</jnlp>
</code>

Hi,
I tried the sample application for JNLP(webpad) it works but not my application. Why ? Webpad actually uses the api to download the jar defined as application is it the case always ? I thought it works just by defining extention tag. What am i missing ? Any help will be appreciated, its urgent
