Introscope - HTTP ERROR 500 - "Problem accessing /webview/console.do. Reason: "

[Private_Member_19084]

Hi experts,

I've installed Introscope 9.15 on Solution Manager 7.1 Sp8.

On calling the Webview I get the following error.

Do I miss some installation step or what is the problem? It seems like a java-library is missing or something...

java.lang.IncompatibleClassChangeError: Class com.sun.org.apache.xerces.internal.dom.DeferredElementNSImpl does not implement the requested interface org.w3c.dom.Node
