Problem uploading avatars

Hi,

 

I have two servers running jiveforums with same configuration. JiveForums 5.5

Aplication server: WebLogic 10.3

OS. Red Hat

Same Classpath

Same jdbc drivers.

 

In one of the servers I don't have any problem with the forum, but in the other I'm getting an SQL Exception when loading an avatar for an user. I get the following error.

 

2009.10.08 09:07:26 [error] Failed to load Oracle JDK 1.4 JDBC drivers.

java.lang.IllegalArgumentException: weblogic.jdbc.wrapper.Blob_oracle_sql_BLOB@9da

Any ideas, I've seen another thread with a similar issue, but it is not stated how it was finally solved

Thanks!

Re: Problem uploading avatars

Hi Proliant,

 

It was my post that you referred to earlier.  We didn't determine the root cause of the problem; it disappeared when we moved the jive forums to a different machine.

 

It was most likely due to having multiple oracle JDBC drivers in the CLASSPATH, as suggested by Greg in the thread you referred to.  My suggestion on how to troubleshoot it would involve using the JSP code I provided, and uninstalling all of the oracle drivers you can find (to the point where jive and the JSP cause compilation errors).  Then try adding the thin oracle driver back in using weblogic connection pooling - the code requires the connection pool to be available at the JNDI name "comp/env/jdbc/jive".

 

Sorry I can't be of more help.

 

Cheers,

Mike Cunneen

Re: Problem uploading avatars

Hello,

 

Would you try loading this same avatar that your forums has an error with on the other forums instance?  Also, have you checked whether you have multiple Oracle jdbc drivers in your classpaths?

 

Thanks,

Kevin
