I'm trying to use one Java Agent to access different System Groups, but I'm not being able to do it.

I did develop two Web Applications, that I did deploy in the same WAS 5.0.2 in the same Virtual Host.

The first application to start is the one that is cappable to acess the respective workflow server. When the second application tries to start it always gives an error. This situation is independent of the first application to start.

Thanks for help.

More details on your WF setup might help.

Hi mmoita

Please look at the following article.
This talks about the following.

http://www-128.ibm.com/developerworks/websphere/library/techarticles/0406_kulhanek/0406_kulhanek.html

This is from the article

Prior to WebSphere Application Server V5, WebSphere MQWorkflow Web Client and WebSphere Business Integration Monitor were deployed into different application servers. This approach was taken because the WebSphere MQWorkflow Java API, which is being used in both the Web Client and the Monitor, is implemented through a Java Native Interface (JNI) wrapper that calls into a C Library. According to the J2EE specification, you can load a native shared library once by an application server. Therefore, the two applications are deployed in two different application servers


Specific concentration should be on

This looks like the reason why you are getting an error while you are loading your second application.

There is a workaround in this article with an example of how to avoid this error. But its specific to MQWF webclient and WBI Monitor.
So, you might have to play around your applications , to find a workaround yourself.

Thanks

Hi,

USE THE NATIVE JAVA API! It will overcome such kind of problems.
