Seam 2 + MySQL 5 + jBPM 3

Seam (jboss-seam-2.1.2) could not start jBPM (jbpm-3.2.6.SP1) causes application deployment fails

02:08:48,718 ERROR [jbpm]] Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener
org.jboss.seam.InstantiationException: Could not instantiate Seam component: org.jboss.seam.bpm.jbpm

Caused by: org.hibernate.PropertyAccessException: could not get a field value by reflection getter of org.jbpm.job.Job.id

jboss-seam-2.1.2 comes with an older version of jbpm-jpdl.jar. Copy the newer one from jbpm-3.2.6.SP1 to replace the one in seam.

Seam (jboss-seam-2.1.2) example Hotel Booking, it causes exceptions during undeployment during JBoss shutdown

17:35:36,421 WARN  [Component] Exception calling stateful session bean default @Remove method: hotelBooking
org.jboss.ejb3.common.registrar.spi.NotBoundException: Requested value bound at name "jboss.j2ee:ear=seam.example.hotel-ear.ear,jar=seam.example.hotel-ejb.jar,name=HotelBookingAction,service=EJB3" is not bound.

Only the Stateful session beans like hotelSearch cause the exception. Inside the example there are jboss.xml which contains session bean registrations. Places this file to seam.example.hotel-ear\EarContent\META-INF.

Seam (jboss-seam-2.1.2) jBPM file for page flow could not be parsed

Caused by: org.jbpm.jpdl.JpdlException: [[ERROR] Unable to parse process definition pageflow.jpdl.xml]
 at org.jboss.seam.bpm.Jbpm.getPageflowDefinitionFromResource(Jbpm.java:169)
 at org.jboss.seam.bpm.Jbpm.installPageflowDefinitions(Jbpm.java:278)

Check if the process definition contains any sub process. If it does, in components.xml, all sub processes MUST be defined before the main process. For example: if cheat.jpdl.xml is a sub process of pageflow.jpd.xml, the follow one will cause the trouble

    pageflow.jpdl.xml
    cheat.jpdl.xml

And this one is correct.

    cheat.jpdl.xml
    pageflow.jpdl.xml

Eclipse + Seam + TestNG Tricky

TestNG gives "Connection Refused" while running on Eclipse

org.testng.TestNGException:

... 2 more

While running TestNG in Eclipse there
will always be 2 VMs involved: the VM of Eclipse and the VM running
the tests. In order to update the plugin UI the 2 VMs are
communicating over a port using a very simple string based protocol.
The exception you are seeing is telling that the 2 VMs are not able to
talk to each other. This is a weird exception that would translate
into: there was impossible to open a communication port between the 2
VMs involved. Off hand, the cause may be: a bug in Eclipse/plugin or
maybe a firewall/antivirus that blocks this.

TestNG/Seam reports ClassNotFoundException issues

This is mostly caused by Class Path configuration, also, Java 6 may be the cause, use Java 5!!

Could not find several required files

It seems that it does not like space in the path T_T, try to set the workspace to somewhere with NO space!! FUCK!

When running test case in Eclipse, TestNG complains bad version in .class file even Java 5 is used

java.lang.UnsupportedClassVersionError: Bad version number in .class file

Make sure everything is Java 5 compliant, such as:

• Project build path


• JAVA_HOME, JRE_HOME


• Java's in PATH (check by java -version)


• The Application Server (i.e. must be JDK5 compiled JBoss AS 5)
