Random error messages in WebI

Former Member

Hi,

We are on BO 4.1 SP2.

Since we upgraded to 4.1, our users get more random error messages than before. We can't tell the exact steps, that lead to the errors, but for example this one appears from time to time in WebI, when applying a filter. The error message box appears and i can find the following log entries in our tomcat logs.

java.lang.NullPointerException: while trying to invoke the method com.businessobjects.sdk.core.server.IServer.process(com.businessobjects.sdk.core.server.IServerRequest) of an object loaded from local variable 'server'

at com.businessobjects.rebean.wi.impl.services.AbstractRebeanService.sendRequest(AbstractRebeanService.java:56)

Any ideas?

We found another possible cause for this issue.  First of all the symptoms that we experienced...  

I got the error when trying to schedule a report.  I set up recurrence to work with a calendar and then clicked on Prompts tab and immediately got the error.

Click OK and I’m dropped out of the Schedule Window.   I can View the report without issue. 

So, we recently upgraded from BOE 3.1 SP6.  I found that I had to re-run the UMT for this report and a few other that were similarly afflicted.  Now, I can schedule the reports as expected and run with successful instances.

Hi ,

We are facing same issue while trying to access webi report block via Qaaws from a dashboard.

Just to clarify, did you need to install both patches or problem was solved after installing 4.1 SP03 Patch 2 ?

I'm asking this because that's my exact patch level and I can't figurate it out.

Regards,

Pablo

Hans,

The issue gets resolved once you restart the SIA. If it still don't solve the problem restart the System and the prompt will go away.

I did that today and it resolved the issue.

Hans,

I am experiencing that same issue, and we have just recently finished our upgrade to BO 4.1 SP2.

We were not having the issue on the prior release.  I am running traces on WebI services to try and track down.

Have you submitted a ticket to SAP?  I am in the process of that now.

Will update thread if I find an answer.

I believe it is a bug and it's related to a user account timing out. It seems to occur in our environment after a userid has timed out.

Hi Hans

I have the same error message as you specified occurring on some of the PC's running the report but not on my own.  I have a reproducible sequence of steps where the last three are click on a report A link to go to Report B, then going back to Report A and clicking next page.    The second page has a bar chart on it.  If you go into report A and go straight to page 2 it works fine.   I though it may be of interest that I can not reproduce this on my machine, though most other users appear to have this problem.  Rebooting does not effect the outcome. We are on BO 4.1 Support Pack 1 Patch 1.

I am continuing investigations and will let you know if I find anything.

Regards

Rodney Evans.

We have the same issue with our multipaged opendocs. Surprisingly the issue occurs only via Load balance URL's. When we go to tomcat URL directly it works.

Here's what happens,

Open opendoc (multipaged and linked), open linked report, go back to original doc, click to navigate to next page. The error posted by Original poster appears.

Please share if you have a resolution for this.

This is a very generic error and does not exactly tell anything about whats wrong.. When you are getting this message while running report?

I will suggest to check if all the Webi servers are in good health..may be try to restart the server once and see if anything improves..

Yes all servers are running and fine.

You are right it's a very generic error, exactly that's the problem, I have no idea where to start to look at. The error occurrs sometimes when people are applying a report filter for example, but not always.

Some times I have seen this when the session is expired.. 

My suggestion is setup a trace when this behavior is observed..

Is the behavior repeatable? if not then it will be quite difficult to get to the root cause..
