You have  SAP PI (Process Integration) in use. During  calling Enterprise Services Builder or  Integration Builder/Directory from local workstation you get an error:

“JAR resources in JNLP file are not signed by same certificate”

Your System administrator might have applied Java Support Packages on PI System.

Applying support packages, a new certificate is imported in PI Server (Java Database) which has to be known by  Java client on windows workstation. In fact that happens automatically when you call Enterprise services builder or  Integration Builder/directory but the reason would be that the already running Java Processes have prevented certificate to be activated.


Restart your local windows workstation.

April showers bring May flowers

If you have PI version 7.31 update your java client to 1.7 on your local workstation.
