Error with JAR Signing

Question

Folk'ses,
I have just done my first JNLP stuff, and I am experiencing a very strange problem:
my application launch works just fine but only every 2nd time!
I alternatingly get the following error: {color:#ff0000}Unable to launch the application.{color}
{noformat}And the details state: {color:#ff0000}JAR resources in JNLP file are not signed by same certificate{color}{noformat}
I perform the exact same operation again without changing anything in between, and hey presto, my application is launched.
Following is my JNLP file:
<?xml version="1.0" encoding="utf-8"?>
<!-- JNLP File for Session Client -->
<jnlp spec="1.0+" codebase="http://oneclickserver9/CONTINUITY" href="/CONTINUITY
/licensing.jnlp">

BS,
thanx for your reply:
You might want to check how the referenced resources/JARs are signed on the serverI do the signing "manually" in a for loop over all jar files:
for f in *.jar; do echo $f; jarsigner -keystore G:/Keystore/continuityKeystore -storepass XXXX -keypass +YYYYY+ $f +ZZZZ+; done
are they getting generated/signed dynamically every time you access the JNLP?no, see above
Could it be possible that different requests be served by different web servers (may be in a cluster)?no, I only have one tomcat server running
