LPS 2.2 on OC4J not working

[jawadz]

I have standalone oacle container for J2EE (OC4J) build 9.0.3. I have deployed LPS-2.2 on the server. When I try to access the examples, I get this error:

Not sure what the problem is. It works fine on Tomcat.
I am evaluating this for my company and it is istrumental that it works with OC4J. Any help is highly appreciated.

Thanks

This lookslike a possible JAVA conflict with the jing.jar.

Does OC4J use jing? Is there a setting for OC4J to tell it to prefer classes in WEB-INF/lib over the container's versions?

[jawadz]

I have extensively checked the libraries used by OC4J and it is not using jing.jar. I have tried the following without any resolution. I placed jing.jar in the OC4J classloader path, I started the server with the minimal set of jars to see if there is any library conflicting with LPS libraries. Here is the entry from the LPS log file, if it is of any help:

Thanks for the response. I appreciate the consideration in this matter.

[bloch]

I'd check all the jars to see if they contain any classes from

com.thaiopensource

-Eric

[jawadz]

I have gone through every single jar that is used by the server and all the deployed applications. I was not able to find any com.thaiopensource structure. It only exist for the jing.jar which is in LPS server.

Any more thoughts/ideas ? I am open for anything right now as I have not moved a single step from where I was.

Thanks

[bloch]

That's a really long CLASSPATH that looks like it might cause other jar conflicts. It could be that you're picking up the wrong iso_relax jar as well.

Do you have a "stock" $JAVA_HOME/jre/lib/ext ?


-Eric

[jawadz]

Yes, I have the stock %JAVA_HOME%/jre/lib/ext and the JDK is 1.4.1. There actually is an improvement, I tried the LPS on OC4J 9.0.4 and it works on that. It is certainly the CLASSPATH issue and I am certain some of the libraries with 9.0.3 are causing problem. I still have to make this work on 9.0.3 though as that is our production environment. I will keep playing with the libraries and see if I can reach a good combination.

Thanks.
