I read seam1.0.0.CR3 DVDStore sample. And I tried to do rollback test.
I think the default transaction mode is REQUIRED so we don't need to write
declarative transaction at the method.
As my understanding there are three types of coding for roolback.
1) Call setRollbackOnly()
2) Anotate @ApplicationException(roolbak=true) for exception trigers rollback
3) Generate System Exception
I write the program for checking #1. The database is MySQL 4.0.26. Seam is
1.0.0CR3. JBOSS is 4.0.4GA.
But it doesn't work. "Transaction is not active" is returned.
Does anybody success to rollback in SEAM?
What I do is
I added the below in faces-config.xml
| <lifcycle>
|
<phase-listner>org.jboss.seam.jsf.SeamExtendedManagedPersistencePhaseListner
| </phase-linstner>
| </lifecycle>
|
|
I added the below in web.xml
| <filter>
| <filter-name>Seam Exception Filter</filter-name>
| <filter-class>org.jboss.seam.servlet.SeamExceptionFilter</filter-class>
| </filter>
|
| <filter-mapping>
| <filter-name>Seam Exception Filter</filter-name>
| <url-pattern>/*</url-pattern>
| </filter-mapping>
|
The program is
| package org.jboss.seam.example.NCI_GW.ejb;
|
| import org.jboss.seam.example.NCI_GW.par.*;
|
| import java.util.*;
|
| // add 0620 for Transaction -----------------------------------
