JNLP-file as returned from the ATEN iKVM-webserver

The ATEN iKVM-viewer works fine with Sun Java (tested on a Windows machine) but fails on F14.

Tracking this down showed that support for jnlp.packEnabled and jnlp.versionEnabled seem to be the missing in openJDK.

Excerpt from JNLP:
<jnlp spec="1.0+" codebase="http://localhost/">
  <resources>
    <property name="jnlp.packEnabled" value="true"/>
    <property name="jnlp.versionEnabled" value="true"/>
    <j2se version="1.6.0+" initial-heap-size="32M" max-heap-size="40M"/>
    <jar href="iKVM.jar" download="eager" main="true" version="1.60.1.0x0"/>
  </resources>


See below on how to test it really fails on these two funtionalities:

javaws from openjdk tries to download the file "iKVM.jar" from localhost and fails.

Sun Java instead downloads: iKVM__V1.60.1.0x0.jar.pack.gz from localhost (using the same JNLP!)

I then manually adjusted the file-names like:
    <jar href="iKVM__V1.60.1.0x0.jar.pack.gz" download="eager" main="true" version="1.60.1.0x0"/>
And that downloaded the file successfully. However it did not execute because of
java.util.zip.ZipException: error in opening zip file


So I manually unpacked the file:
unpack200 liblinux_x86_64__V1.0.3.jar.pack.gz liblinux_x86_64__V1.0.3.jar

And modified the jnlp to read:
<jnlp spec="1.0+" codebase="./">
  <resources>
    <property name="jnlp.packEnabled" value="true"/>
    <property name="jnlp.versionEnabled" value="true"/>
    <j2se version="1.6.0+" initial-heap-size="32M" max-heap-size="40M"/>
    <jar href="iKVM__V1.60.1.0x0.jar" download="eager" main="true" version="1.60.1.0x0"/>
  </resources>

And then it finally started successfully without further problems.
