Hi Michael
You said for for non-JBoss examples, please see the “jpa” and “jee5″ examples in Seam distribution. I am trying to run “tomcatjpa” example from seam book on tomcat and I am getting
Error configuring application listener of class com.sun.faces.config.ConfigureListener
java.lang.NoClassDefFoundError: javax/el/CompositeELResolver

I have succesfully run “tomcatjpa” with old seam book distribution ( before you updated to 2.0.0).

I followed all steps in your book to run “tomcatjpa” application. Are there any changes in steps for seam 2.0.0?

Hi Michael,
I’ve built helloworld.ear as described in
chapter 2. I am using JBoss 4.2.1.GA, jboss-seam-2.0.0.GA, JDK 1.6.0_03.
At JBoss deployment time I have the following exceptions:
10:23:30,068 WARN [ServiceController] Problem starting service jboss.web.deploy
ment:war=app.war,id=1562089102

Any idea what’s going on and how to fix the problem.
Regards,
Vitaly

HI Micheal yuan

I have read almost all the chapters in your boook. Real cool stuff…no junk

I’m new to J2EE but want to start with the currrent technologies. Well i want to also do real time developments. I’ve been trying for a month to develop a crud example with RHDS. its always given me a problem. I’ve managed to get around all the obstacles except one that says FaroukOnline not bound…well i dont kno want that means….and nothing i’ve done has worked.

So i stoped using that ide.
I have developed an enterprise application with EJB3 and JSF without seam in netbeans 6. done all the redundant coding since Seam made it all easy. I want to deploy on JBoss 4.2.1 that ejb deploys but the client doesnt…i get error 404 but the war is in the deploy folder

please help me

and how can i use seam in netbeans 6 since there is no update center option in the tools drop down

For non-JBoss examples, please see the “jpa” and “jee5″ examples in Seam distribution.

But the last time I tried WebLogic 10, it has some EJB3 issues. So, for now, you can only use JPA + Seam POJO in WebLogic 10.

Hi Michael,

You have published a very good example’s, which would make any one comfortable to start working with seams in jboss, but it would be good to have some working example which would work with weblogic 10 and any latest application server which supports jee5.

By this I am sure that seam would be one of the favourite frame works of any j2ee developer in future.

As I still have lot of issue in deploying the seam sample application in weblogic 10 and which really stops me to use this frame work in our future development.

Thanks

[...] Luckily, those steps are chronicled here (by Michael Yuan) and here (by Nicolas Leroux). Oh, and Michael’s site has updated samples from his book. [...]

I have not been able to get the seam jpa example working on websphere. [Tried Seam 2.0.0.BETA1 & 1.2.1GA with both WAS xpress 6.1.1 & WAS std 6.1.0.3...most success with WAS express & 2.0.0BETA1]

It deploys but all actions fail. Could it be related to:
java.lang.ClassCastException: org.jboss.seam.persistence.EntityManagerFactory incompatible with javax.persistence.EntityManagerFactory

My understanding is that WAS does not support EJB 3.0 without a beta feature pack. Is this example using the embeddable EJB3.0?

Any pointers would be really appreciated. (I’m new to seam & WAS, so could easily be a config issue.) Thanks.
