Are you sure that they're not getting included (e.g. not actually in the WAR file), or that they're not activated? If your dependency (in the web modules) on the spa module is default scope, then it should be including them. Derek On Wed, Sep 16, 2009 at 10:32 PM, Charles F.

[Lift] Re: JPA with more than one front end (Maven! sigh...)
Actually, I figured that out. They're included. But I have a different problem now -- one that you might know the answer to. I'm loading this war file up in JBossWeb (basically a hopped-up Tomcat) and when I try to use it, I get a problem with transactions. I assume this is something in the JBossWeb server, since I have nothing in my code to cause that. Something on the server wants that jta.jar in there. So I tried commenting out the javax.transaction exclusion in the pom.xml file for the spa project, and that added the jta jar to the lib, as expected. That also solved the problem with the server. But now when I merge objects to the database, the objects are created, but none of the properties are saved. It's very strange. I am wondering if this is a transaction issue. And just out of curiosity, why is the javax.transaction exclusion in there? I've often wondered about that. Chas.

[Lift] Re: JPA with more than one front end (Maven! sigh...)
JBoss includes its own JTA libs, so you need to set the scope to exclude the other ones or else they'll conflict. Generally with any JEE container you would need to do that, since JTA is part of the spec. What exactly do you mean by the objects are created, but none of the properties are saved? Is an insert occurring but no fields are saved? If it's transaction related it's almost always a binary outcome (works/doesn't work), not something in between, although I've seen enough oddities to know that there are always exceptions :P Derek On Thu, Sep 17, 2009 at 12:03 PM, Charles F.

Also, if you're loading this up in JBoss, it might make more sense to bundle the artifacts into an EAR, unless you intend for the two web modules to have completely separate persistence units (e.g. different DBs, etc). Maven has a nice plugin for doing EARs. I can send a sample pom.xml if you'd like.

Yes, I would expect the work/doesn't result, too. So maybe it's correlation not causation and I should look for something else. It's definitely saving the objects, just not updating the fields.

OK, well, I don't know if this will work in JBoss Web, but here it is anyways. This shows how you can create an EAR from some web modules, a JPA module and a library (shared between all three classloaders).
