One thing I noticed was a problem finding a log4j class. I can't remember if this is distributed in the install zip or not. It might not be since Tomcat, JBoss, and others generally have this. You might try getting the log4j.jar and adding it to your webapp's lib directory.
Sorry for the delay, just getting back from a long weekend in New England....
At this point, I don't know what to tell you. It's most likely a problem with the jahia portal implementation. AFAIK, this was not done by the jForum folks since there is no org.jahia package code in the repository.
Perhaps the jahia support/developer community can better help you get this working? [originally posted on jforum.net by monroe]
did you find a solution for your problem ?
I've got exactly the same exception (Template for action insertSave is not defined) when I use datasource. But for me, it doesn't work neither in IE neither in FireFox [originally posted on jforum.net by toomtooms]
I find the solution !!
The problem comes from a cast in the OracleUtils.writeBlobUTF16BinaryStream method. Weblogic wraps the oracle classes. Therefore, the BLOB object is a weblogic.jdbc.wrapper.Blob_oracle_sql_BLOB object an not oracle.sql.BLOB object.
The solution is to use the last version of the JForum code. It's corrected in it ! [originally posted on jforum.net by toomtooms]
