Using Torque and JBoss

[jexenberger]

Hi,

Has anyone ever managed to get Apache Torque to work using JBoss, I have tried but it keeps complaining it can't find one of my Torque generated classes

[lpmon]

Ditto.

The class loader cannot find 'Torque' class or any other classes in the torque related jars.

I have beat on this a while with no success. I have to admit all of this is new to me. However, I got Velocity working with JBoss fairly easily. But, Velocity is accessed at a different point (template in a page) and I am trying to use torque inside the servlet code.

My question: If I put the velocity .jar files into the war and JBoss found them why can't I put the torque jars in the same place and they be found?

My experiment:

- Added the torque jars at into the war file (WEB-INF/lib same place as a bunch of other apache jars including velocity)
- Modified the Dispatcher.java in JBoss test app (Dukes Bank) to use Torque.

I get class not found exception. I tried adding the jars to the class-path in the manifest with no luck.

HELP!

Does Torque generate classes at runtime?

[lpmon]

I am new to Torque but I do have an answer to this.

One uses the Torque generator to create classes. Then these classes are added to a web app along with some Torque runtime classes. My problem is JBoss cannot find the classes for the Torque runtime. I set things up as described in my earlier post.

I just tried setting the JBoss startup classpath to include the Torque jars. (I changed run.bat). JBoss still cannot find the classes.

I got past my class not found problems. In another thread I saw info. about differences between versions of JBoss. I am running 3.2.3. The suggestion for someone having classpath problems was go into the Tomcat jboss-service.xml file and change the 'UseJBossWebLoader' property to 'false'. I did this and everything started working! Path to the changed file: server\default\deploy\jbossweb-tomcat41.sar\META-INF\jboss-service.xml

Okay ...., I had changed so many things my experience tells me I need to make sure I understand "how I got to here". If I change UseJBossWebLoader back to true it still works. Mystified!

I hope that you've sorted this out by now. However, assuming that someone else will come along and wnat to know the answer, here's what I found when I recently integrated Torque into a web app running on JBoss.

First, you need to put the torque jars (torque/lib) under server/default/lib so that they are available.
Second, you need to import the torque.properties file into your app so that all of its paramaters are available to the servlet/JSP.
Third, you need to load said file into the page, before you can call the torque classes.

I've put the details into a Torque and JBoss page which explains it all.
