java.lang.reflect.invocationtargetexception error

[Former Member]

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

More insight to the problem:

- User is able to open/create reports on different machine.

- Upgraded his Java pack to Java 6 update 29 - still getting the same error message

I am quiet convinced that there is no problem with the user or the BO system but has to do something with the individual system. Suggestions are welcome.

Best Regards

Hi Ritesh,

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

Hi All,

I am also getting this error message but not when opening a report but when formatting a cell
I tried to format the cell by right clicking on the cell and selected format cell option then I observe this error there is no problem in opening and modifying the report but formatting the cell is possible by selecting the cell and formatting through foramt tab.

Can anyone help me in finding the cause for this.

Regards,
Sravan.

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.
