Thanks for the link.

Package binaries were accessible using a URL as below, without username/password.

http://<server>:<port>/drools-jbrms/org.drools.brms.JBRMS/package/<package-name>/LATEST

Our use of BRMS is currently stalled. We did not enable SSL on Weblogic.

Thanks Atif,

I did find some documentation on configuring new realms. In case you are interested: http://edocs.bea.com/wls/docs81/secmanage/realm.html#1186823

After you enabled security, did you have to do some special configuration for the Rule Agent to have it access the package URLs (under BRMS).

With security enabled, won’t the Rule Agent (or something on the client side) need username and password to download pkg binaries from the URLs pointing to deployed package snapshots?

Also did you enable SSL on Web Logic? If yes, I guess a key store would have to be used on the client side.

Thanks once again.

I did not have to create a new security realm. I added users/group in default ‘myrealm’. I have not tried using external LDAP. Weblogic documentataion/user list might be helpful in this regard.

Atif,

Thanks a lot. That was very helpful. I have a couple of questions though.

Did you have to create or configure a security realm? Weblogic has a security realm called “myrealm” configured by default. Do you know if the UsernamePasswordLoginModule uses “myrealm” by default?

I need to use an external LDAP (and not the one build in with Weblogic server ). I guess I would have to configure a new realm and providers. Do you know what needs to be done to have the UsernamePasswordLoginModule use the new realm (and hence the external LDAP).

Thanks again for your help.

Paul,

I was able to run BRMS on Weblogic. Looks like the Weblogic Workspace IDE was creating some jar conflicts. When I created a domain, I selected the option to configure it for Workspace also.

After trying many different things (and getting thoroughly frustrated J ), I created a new domain and configured it just for the Weblogic server. Put the right JSF jars in domain lib and deployed BRMS war from the console and it started up fine.

I have some exceptions related to DB2 Persistence Manager, but the application is running.

Thanks for your help.

BTW, have you ever configured and used a Weblogic JAAS module with BRMS.

Thanks,

Vikas

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 :-(.

Thanks a lot for writing back.

>>>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?

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

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
