Vikas,

I've always used Sun's JVM; mainly out of habit and one less thing to investigate if things go wrong. It's worth trying Sun's in this case if you're using the JRocket JVM.

Can you look at the Seam source code to see what is causing the NullPointerException at
GWTToSeamAdapter.java line 67? I don't have the source to hand at the moment. My guess is that there is an issue on the server somewhere (i.e. some missing or conflicted libs) but have no more detailled wisdom :-(.

Paul,

 

Thanks a lot for writing back.

Sorry if that didn't come across right. That page did help a lot. I followed the instructions on that page. That fixed the JSF related exceptions that I was initially getting. But then I got that other NullPointerException whose stack trace that I listed in my last email. That's the only exception that I see in the log. And The BRMS shows me an error message and then doesn't display the login page.

 

And I did bring in the JSF dependencies. I still get the same exception.

 

Your Wiki page is very good. I just am getting an exception that I am unable to find a solution for.

 

Do you know if it matters whether I use the JRocket JVM or Sun's JVM in the Weblogic server ?

 

Also, did you get a chance to look at this http://www.seamframework.org/Community/GWTRPCCallFails

 

I would appreciate any other input that you give.

 

Regards,

Vikas

Vikas,

Thanks for your note - I'm the person that wrote the JBoss_Drools_BRMS_on_Weblogic page that you mention.
Just so that I can update the page, when you say 'that didn't help' can you tell me what problems you are seeing / what you feel is missing?

I'm guessing that you've already seen the page http://wiki.jboss.org/wiki/JBRMSjsfdependencies - did it help you at all?

Regards

Paul

Hi All,

I'm trying to run BRMS 4.0.7 on Weblogic 9.2.0.0. It won't run and I'm
getting the exception listed below.

I looked at the Drools Wiki entry :
http://www.firstpartners.net/kb/index.php/JBoss_Drools_BRMS_on_Weblogic

That didn't help.

I also found something about this exception at Seam's website:
http://www.seamframework.org/Community/GWTRPCCallFails

As per the instructions mentioned in the above website, I brought the
jboss-seam-remoting.jar into my lib directory, but that didn't help.

Does anybody have any idea? Has anybody been able to successfully run
BRMS on Weblogic ?

Thanks,
Vikas
