Unable to launch application with webstart

Question

Hi all, hope someone can help
I recently installed j2se 5.0 update 1 and uninstalled my earlier version of 1.4.2_06.
Since uninstalling the earlier version I am unable to run my application, I get the following error:
An error occurred while launching/running the application.
Title: Uploader
Vendor: Me
Category: Launch File Error
Could not parse launch file. Error at line 0.
This is from the exception tab:
JNLParseException[ Could not parse launch file. Error at line 0.]
     at com.sun.javaws.jnl.XMLFormat.parse(Unknown Source)
     at com.sun.javaws.jnl.LaunchDescFactory.buildDescriptor(Unknown Source)

     at com.sun.javaws.Launcher.handleLaunchFile(Unknown Source)
     at com.sun.javaws.Launcher.run(Unknown Source)
     at java.lang.Thread.run(Unknown Source)
Here is a copy of my jnlp file
<?php
header('Content-type: application/x-java-jnlp-file');
echo '<?xml version="1.0" encoding="UTF-8"?>';
echo '<jnlp spec="1.0+" codebase="http://www.******.com.au/uploader/fileuploader" href="fileuploader_jnlp.php">';
echo ' <information>';
echo ' <title>Uploader</title>';
echo ' <vendor>Me</vendor>';
echo ' <homepage href="index.html" />';
echo ' <description></description>';
echo ' </information>';
echo ' <resources>';
echo ' <j2se version="1.4"/>';
echo ' <jar href="fileuploader.jar" main="true" />';
echo ' <jar href="JimiProClasses.jar" />';
echo ' </resources>';
echo ' <application-desc main-class="fileuploader.FileUploader">';
echo ' <argument>http://www.********.com.au/uploader/fileuploader/upload.php</argument>';
echo ' <argument>25/</argument>';
//echo ' <argument>100000</argument>';
//echo ' <argument>thomas:test</argument>';
echo ' </application>';
echo ' <security>';
echo ' <all-permissions/>';
echo ' </security>';
echo '</jnlp>';
?>
The application runs fine if I uninstall version 5.0 and revert to 1.4.2_06
but I would like it to be compatible with newer versions of java.
P.S. Im not a programer so if you could explain to me in simple terms what Im doing wrong it would be great.
Thanks in advance

I'm a programming illiterate having the same problem with the latest java.

What am I supposed to do? Java Web Start is supposed to be dummy friendly :(
Edit: Problem solved! It seems the file wasn't completely removed and parts of it were corrupted under the java viewer-resources (old cache messing it up). Once removed the problems were gone, so anyone having this problem should check that out :D
