deployment question (dependent jar files)

[bjwaski]

I'm having a bit of trouble wrapping my head around the EJB3 deployment process. I see how I can deploy my EJB jar file (ie. myejb.jar) directly into server/default/deploy, but what do I do with jar files that my EJBs depend on (ie myapi.jar)? Do I just put them in server/default/lib? (although I'd definitely prefer not to do that)

Thanks.

Suggest you look at deploying in an ear file.

I put all jars/wars into the root of the EAR and then reference them in META-INF/application.xml.

i.e.

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application_1_4.xsd">
<display-name>MyAppEAR</display-name>

PortletUtils.jar


jboss-seam.jar


jboss-seam-ui.jar


MyAppEJB.jar



<web-uri>MyAppWeb.war</web-uri>





Don't forget META-INF/jboss-app.xml to define your class loader i.e.

<jboss-app>
<loader-repository>
seam.jboss.org:loader=myapp-loader
</loader-repository>
</jboss-app>

Hope this helps.
Andy.

Sorry - should have previewed before posting. Added some spaces in the tags to get it all in the post.

Andy,

Thanks for your quick reply. I think that mostly makes sense, although I don't follow the classloader part. Any chance you could point me to the docs on that?

Thanks for your help.

Sure,
Checkout the following wiki pages. Subject that is a must to avoid headaches with jar versions, etc.
