I am attempting to run an Eclipse RCP application using Java Web Start. However, I encounter this error after the application is downloaded and run:

JNLP JREDesc in Component ignored: null

After that, the application closes. What is the workaround for this?

Attached is my main JNLP file.

I am using JDK 7 update 4. I tried JDK 6 update 31 as well as JDK 7 update 3 but the problem persists.
  • Attachment: start.jnlp
    (Size: 2.07KB, Downloaded 126 times)

Hi,

I had the same problem and solved it.
(I'm using Eclipse 4.2 M6 and develop an e4 application).

I think "JNLP JREDesc in Component ignored: null" is not your problem.
The error will disappear if you remove the j2se definition(s) in your referenced jnlp file(s). However, I assume this is not your problem.

In my case, I didn't use the "osgi.bundles" property which is also missing in your start.jnlp and many tutorials.

You have to use the "osgi.bundles" property in order to "start" all your required bundles.

For instance, if you've defined
"plugins/com.ibm.icu_4.4.2.v20110823.jar" and
"plugins/org.eclipse.core.commands_3.6.0.I20110111-0800.jar"
in your referenced jnlp files, then just add the following property to your "start.jnlp" file:

<property 
    name="osgi.bundles"
    value="com.ibm.icu@start,org.eclipse.core.commands@start"/>

Just do this for all your required resources.

Regards,
Rouven
