Java WebStart Exception - Repository/Directory don't start

[Former Member]

Dear experts,

in our test environment I can access all XI related programs. But when I want to start the productive Integration Repository or the Integration Directory I get the following error message from Java WebStart:

java.lang.NoClassDefFoundError: java/security/CodeSigner

at com.sun.javaws.security.SigningInfo.setContains(Unknown Source)

at com.sun.javaws.security.SigningInfo.overlapChainLists(Unknown Source)

at com.sun.javaws.Main$1.run(Unknown Source)

at java.lang.Thread.run(Unknown Source)

It also says "JAR resources in JNLP file are not signed by same certificate" .

Do you know, what this means and what I have to do, to get this started?

Best regards,

David

Hello David

What PI release and SP version are you on?

Check note #929144 - XI30:Jar Files signed by different certified keys.

Go to admin tab of your java stack home page->On the Directory tab, choose Java Web Start Administration->Re-initialization->Try to download ID from the beginning.

Hi,

I also faced the same error, I have solved myself. When u open SXMB_IFR and go to the Administration tab and Check for the JAVA WEBSTART and Restart from there. U problem will be solved..

David,

In addition to what Mark suggested, you can try clearing the Java cache (from Control Panel -> Java). If your PI server is on two instances - Central and Dialog, this issue might happen.

Hope this helps.

Ask your basis if they have made any changes to certificates on the prod server. BASIS knows how to solve this error.
