Java Web Start Jar signing Issue?

Question

I'm trying to run this Java application (jar) via Java Web Start and am having an incredibly difficult time.

Here's my current JNLP source:

<?xml version="1.0" encoding="utf-8"?> 
<jnlp spec="1.0+" codebase="http://localhost:8080/" href="Test.jnlp">
    <information>
        <title>Jnlp Testing</title>
        <vendor>YONG MOOK KIM</vendor>
        <homepage href="http://localhost:8080/" />
        <description>Testing Testing</description>
    </information>
    <security>
        <all-permissions/>
    </security>
    <resources>
        <j2se version="1.6+" />
        <jar href="TestJnlp.jar" />
        <jar href="lib/appframework-1.0.3.jar"/>
        <jar href="lib/junit-4.7.jar"/>
        <jar href="lib/org.eclipse.swt.win32.win32.x86_64_3.100.0.v4233d.jar"/>
        <jar href="lib/org-netbeans-modules-java-j2seproject-copylibstask.jar"/>
        <jar href="lib/sqlite-jdbc-3.7.2.jar"/>
        <jar href="lib/swing-worker-1.1.jar"/>
    </resources>
    <application-desc main-class="proteotypic.ProteotypicQuantificationApp" />
</jnlp>

Upon running the JNLP file, I get the following Error:

JNLPException[category: Launch File Error : Exception: null : LaunchDesc:

I have signed all the jars except lib/org.eclipse.swt.win32.win32.x86_64_3.100.0.v4233d.jar - if I sign that one too, I get a different exception:

After doing "javaws -viewer" and re-running the JNLP, I get:

Try use javaws -viewer to wipe any trace of your previous attempts. — pmoleri
It seems like the first exception, as recursed said you have to sign all the jars with the same singature. Have you sign them signed all before the last attempt? — pmoleri
Try stripping all signatures from all Jars then signing once with the new certificate. — Andrew Thompson
Andrew Thompson and pmoleri - thank you so much. I did exactly what you said and it worked. First, I stripped all the signatures and then reassigned using my own signature! How can I rep you guys? Do you need to "answer" the question? — sudo

You have to sign the jar file. You can do this yourself using keytool, but if you plan on deploying this, I would recommend getting it signed by Verisign or a company like it.

If you just need a temporary fix, signing it yourself for testing is fine.

Here is an easy to use tutorial.
