Correct
I have just run jforum-2.1.8 on jboss--4.2.3portal-2.7.0.CR1 !!! after exactly 1 year of failure !!!, i was just giving up. It's so easy you won't believe it !!!
How to run jforum on JBoss
What i noticed is JBoss has problems decompressing war files just as andune76 above mentioned so the idea is just to give it uncompressed files.
Now JForum installation files come in 3 flavours
1) .zip file
2) .war file
3) .src.zip
Option 1
The easiest file to use is the .zip coz this simply contains the folders in an already expanded format, you simply need to unzip the package, (it created a folder called jforum-2.1.8), i then simply copied and pasted it into JBoss JBOSS_HOME]/server/default/deploy/ folder and renamed the folder to
jforum.war which is a more user friendly name when it comes to typing the web address(Note the .war extension). Thats it !!!
*****Headaches come because on
testing we try to immediately test using the address like
http://localhost:8080/jforum/
NO, FOLLOW installation instructions which say: the next step is to install your jforum by going to
http://localhost:8080/jforum/install.jsp
This now takes you to a page to configure your jforum. Fill in the deatails according to your environment. Another catch here is you must have simply created an empty jforum database coz jforum installation doesn't create a database for you, it simply fills an already existing database with Tables and data !!!, so in my case, i use MySQL, so i just opened MySQL Administrator tool and created a new Database Schema(Database) called jforum then went on with the installation and on completing, thats when you can now test using an address like
http://localhost:8080/jforum/
And voila !!!
Option 2
Now if we choose to install using the war file, the problem is we need to find a way to decompress the files. And Apache Tomcat can do that for you, in my case i had another Tomcat installation so just used it to decompress the war file for me into expanded folders(Just copy and paste the .war file into Tomcat's webapp folder and it will expand/decompress the war - it created a folder with the name jforum-2.1.8 in my case). Next i just copied the jforum-2.1.8 folder from Tomcat and pasted it into JBoss JBOSS_HOME]/server/default/deploy/ folder and renamed the folder to
jforum.war which is a more user friendly name when it comes to typing the web address(Note the .war extension), proceed as above.
POSSIBLE ERRORS
You might get a log4j error as below:
04:49:06,812 INFO [TomcatDeployer] deploy, ctxPath=/jforum, warUrl=.../deploy/jforum.war/
04:49:07,172 ERROR [STDERR] log4j:ERROR A "org.jboss.logging.appender.FileAppender" object is not assignable to a "org.apache.log4j.Appender" variable.
04:49:07,172 ERROR [STDERR] log4j:ERROR The class "org.apache.log4j.Appender" was loaded by

04:50:13,484 INFO [STDOUT] 04:50:13,469 INFO [JForumBaseServlet ] Starting JForum. Debug mode is true
SOLUTION
1) You can even ignore it, mine worked
2) Another Solution. The error is caused by a conflict between your application's log4j.jar file and JBoss log4j.jar file. This is because JBoss comes with log4j.jar file already loaded and so this will conflict with jforum log4j.jar file
Solution- just delete the log4j.jar and also commons-logging-api.jar files from the WEB-INF\lib directory of your jforum so that jforum uses the log4j.jar file in JBoss and restart your JBoss the errors should clear
hope it helps !!!
