Hi All,

Came across a strange issue with one of my users. He is getting error message as 'java.lang.reflect.invocationtargetexception' while trying to open/create any of his WEBi reports. We are currently on Business objects 4.0

Hi Ritesh,

Even I was facing the same issue, un-installing and re-installing Java worked for me.

Solution was Upgrade the Java pack to the latest version. But did not work the first time but worked second time.

Hi All,

Finally the issue is resolved. The user was on Win XP , Upgraded his system to Win 7 (Currently all of our systems are on Win 7). Java was installed fresh and all is up and running.

One observation was while uninstalling Java remove all the files and then do a fresh installation.
