Issue with the petclinic example (java webstart one)

Hi all, i am trying to ru the petclinic example using the war & Java webstart.

Steps i made:

put my keystore in the petclinc root dir
edited the project.properties to configure the keystore
built spring-rcp using: ant alljars
built petclinic using: ant warfile

Everything goes fine ( i had to edit the petclinic build.xml to add source="1.4" to the javac task)

I then deploy the war in my webapp, so far so good. Once i try to start the standalone app, java webstart is launched, it's fetching all jars and then say:
-------------------------------------------------------------------------
Unable to launch petclinic RCP, standalone edition:


An error has happened while launching the app:

Title : Petclinic RCP, Standalone Edition
Provider : The Spring RCP Team
Cat : Error in the jnlp file


JAR ressources defined in the JNLP have not been signed by the same certificate
-------------------------------------------------------------------

I checked all the JARs included in the jnlp and there are signed by the ant warfile target....

Any ideas ?

Thanks in advance

This should be fixed now thanks to Jim.
