Safari Issue: java.lang.ClassFormatError: Incompatible magic value 1013478509 in class file

Question

Facing issue invoking java applet from my jsf page using JNLP file on Safari browser in Windows: java.lang.ClassFormatError: Incompatible magic value 1013478509 in class file

I am able to invoke the same applet properly in Firefox, Chrome and IE.

This is how i am using the jnlp reference in my faces page:

<object classid="java:my.oddc.client.SimpleScanApplet.class" 
                    type="application/x-java-applet"
                    height="100%" width="100%" >
    <param name="jnlp_href" value="/wcc/wcc/upload/scan_client.jnlp"/>
    <param name="ServerURL"
          value="#{pageFlowScope.UploadBean.scanFileURL}"/>
</object>

Alternatively, i tried using embed and applet tags but didn't help.

Also, i have a mandate to pass few parameters to the applet after invoking.

The scan_client.jnlp file contains references to the required jars and nativelibs.

Help appreciated..on what to make it work on Safari (Windows)?

The magic value spells <htm so it is likely there is a 404 in there (resources are not where the object element suggests they are.

Facing this issue only on Safari. If it was a resource conflict it should have equally not run on any other browsers. – Praveen Singh Aug 30 '12 at 06:52
