Exceptions on Seam CVS20070322

[gus888]

Hi there,

When I moved to Seam Seam CVS20070315 and Seam CVS20070322 from Seam CVS20070305, I always got the following "NoSuchMethodException" exception:

2007-03-22 22:14:13,609 ERROR [com.icesoft.util.SeamUtilities] Exception loading seam environment:

In addition, I also got the LazyInitializationException:

org.hibernate.LazyInitializationException: could not initialize proxy

The strange thing is that there was no the exception on CVS20070305. I use

<core:managed-persistence-context name="entityManager"
 persistence-unit-jndi-name="java:/cvnEntityManagerFactory"/>

Any help is appreciative.

java.lang.NoSuchMethodException always means that you have incompatible jars floating around. Probably two copies of jboss-seam.jar.

[gavin.king]

Oh, I'm sorry, that's NoSuchMethodError, of course.

The cause of this one is an incompatibility b/w Seam 1.2 and icefaces. It's our fault, I actually had been warned that icefaces is using that method of our internal APIs and there is a comment in the code.

However, we broke it by this commit:

http://fisheye.jboss.com/browse/JBoss/jboss-seam/src/main/org/jboss/seam/core/Manager.java?r1=1.155&r2=1.156

So either Seam needs to provide a backward compatible overloaded version of the method, or icefaces needs to be updated. It's probably better if we update icefaces, since otherwise some new functionality won't work.

Hi Gavin, thanks for your reply. How about the second LazyInitializationException on the first thread? It seems I should not get the Lazy exception since I use Seam persistence manager. My code works fine in Seam1.2.0Patch1, but failed in the CVS. Thanks.

[gavin.king]

I have no idea, since you gave precisely zero information about it.

BTW, the incompatibility with icefaces is papered over, I deprecated the method instead of removing it.

[gus888]

Hi Gavin,

I tested them on CVS20070326, and it seems that the two exceptions were fixed. BTW,

I deprecated the method instead of removing it.

It means the Seam persistence was deprecated? Thanks.
