[EJB 3.0] - CMT in Stateless SessionBean (EJB3.0)

by stewchicken

Dear all, I encounter a roll back problem for my transactions in my stateless session ( implemented under EJB3.0 standard ). According to below quoted sentence from JAVAEE5.0 Tutorial. If I didnot explicitly mark transaction for my stateless session's methods then all those methods are automatically Contain transactin managed , is it correct? but it seems .the method doesnot roll back successfully when a exception happened inside it. I used JBoss4.0 + Stateless SessinBean (no explicit transacation demarcation used ). Any hints? Is it a transacatin problem from JBoss or my misunderstanding to CMT for Stateless Session Bean? Thanks in advances Container-Managed Transactions In an enterprise bean with container-managed transaction demarcation, the EJB container sets the boundaries of the transactions. You can use container-managed transactions with any type of enterprise bean: session, or message-driven. Container-managed transactions simplify development because the enterprise bean code does not explicitly mark the transaction's boundaries. The code does not include statements that begin and end the transaction. By default if no transaction demarcation is specified enterprise beans use container-managed transaction demarcation.

[JBoss Seam] - Re: Seam + Portlets + JSF + Facelets problem: Exception in P

by andyd

Ok, so I have something working now, but I have problems accessing images in a portlet WAR file. I see some of the JSF based portlets in the main portal deployment include a call to getContext() to merge the front of the URL to the image name. Any idea how you view images with facelets i a portlet? Thanks, Andy.

[Beginners Corner] - Where is the database in the exmaples? :-)

by SpecialAgent

Hey guys, I just tried out the booking example... its just starting the server... ant deploy in the examples dir and it runs fine.... so I added a new user in the app and that works well too... so... i didnt set up a database or something... where is it? I do have some suggestions about this: - Either it hasnt a database and everything is stored as Beans without storing or - it uses something like the derby DB... but i didnt find anything in the examples dir.. Thanks.

[Clustering/JBoss] - Re: Cluster Membership after Network Failure

by dfisher

I downloaded JGroups 2.4 CR2 and replaced the JBoss jgroups jar with the jgroups-all jar. I now get this Exception when the node-2 joins the Partition: anonymous wrote : | 2006-09-25 15:59:59,426 WARN [org.jboss.ha.framework.interfaces.HAPartition.DefaultPartition] failed unserializing message buffer (msg=[dst: , src: X.X.X.2:7800 (2 headers), size = 304 bytes]) | java.io.StreamCorruptedException: invalid stream header | at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:737) | at java.io.ObjectInputStream.(ObjectInputStream.java:253) | at org.jboss.invocation.MarshalledValueInputStream.(MarshalledValueInpu tStream.java:74) | at org.jboss.ha.framework.server.HAPartitionImpl.objectFromByteBuffer(HAParti tionImpl.java:144) | at org.jboss.ha.framework.server.HAPartitionImpl.handle(HAPartitionImpl.java: 967) | at org.jgroups.blocks.RequestCorrelator.handleRequest(RequestCorrelator.java: 623) | at org.jgroups.blocks.RequestCorrelator.receiveMessage(RequestCorrelator.java :508) | at org.jgroups.blocks.RequestCorrelator.receive(RequestCorrelator.java:331) | at org.jgroups.blocks.MessageDispatcher$ProtocolAdapter.up(MessageDispatcher. java:763) | at org.jgroups.JChannel.up(JChannel.java:1078) | at org.jgroups.stack.ProtocolStack.up(ProtocolStack.java:377) | at org.jgroups.stack.ProtocolStack.receiveUpEvent(ProtocolStack.java:393) | at org.jgroups.stack.Protocol.passUp(Protocol.java:538) | at org.jgroups.protocols.pbcast.STATE_TRANSFER.up(STATE_TRANSFER.java:163) | at org.jgroups.stack.UpHandler.run(Protocol.java:60) | Is there something else I need to do to upgrade JGroups?

No biggie - I went through the same thought process as you did when I moved to JBossIDE 2.0.0 (where the heck did the launch configuration stuff go!)...

Again, read the forums. The way you launch JBossAS is now different in 2.0.0 than previous versions. The launch configurations uses the Server stuff in Eclipse 3.2. I use 2.0.0.beta with 3.2 for launching JBossAS (and to debug an EJB app I have) and it seems to work nicely for me.
