[JBoss Seam] - Re: Seam components inside java class libraries

by gbc＠gmx.de

Try adding an empty file called seam.properties at the root level of your jar. At least that works for my seam components (except EntityBeans) to be in an external jar.

[Messaging, JMS & JBossMQ] - Re: Using DeliveryMode.NON_PERSISTENT

by ejb3workshop

Now that I have it working without writing it to the interim cache database I would have expected a performance improvement, yet there doesn't seem to be one. To dispatch 4000 messages still takes around 12 seconds with or without persistence.

[JBoss jBPM] - Graphical Process Designer Problems

by miroth

Hello, I'm an absolute beginner in jbpm so I started today to install the Graphical Process Designer. 1. I downloaded and extracted the the package jbpm-jpdl-suite-3.2.2.zip 2. I downloaded the package eclipse-SDK-3.3-win32.zip as it is adviced in the designer subdirectory 3. I download and extracted the package apache-ant-1.7.0-bin.zip 4. I changed to f:/jbpm-jpdl-3.2.2/designer 5. I opened the file build.properties with the editor and change the following line eclipse.local.path=f:/download/eclipse 6. I started ant with "ant.bat install" Everything works !! When I start the designer now and create a new process project and click on the src/main/jdpl/simple/processdefintion.xml file the editor opens. The problem is that the context menu (right mouse button) seems not complete, when I click on a node I just get the Eclipse menus like "Run as" "Debug as" and so on, but I miss the menu entries like "add task" or "add actions". The swimlane tab is also vanished. What I am doing wrong ?

[Messaging, JMS & JBossMQ] - Re: JMS msg get redelivered although setting retry to 0

by adrian＠jboss.org

Ok, I think I understand what the problem is. The issue is that the failover node doesn't know that the message was already delivered. The node (the original node) that did know has crashed. The problem comes because the failover node uses the transaction log to recover the state to the "last known good state" of the message (which was in your case before the message was delivered to the MDB). The only way I can see to fix the problem, would be to update the redelivered status and redelivery count of the message in the database before the message is delivered to the client (instead of when the server receives the NACK/rollback - which it won't do if the server crashes - it will do it if the problem is just the client loosing connectivity). i.e. in BasicQueue http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/trunk/jbossmq/src/main... This would involve moving the code in "nackMessage()" | try | { | ... | | // Set redelivered, vendor-specific flags | message.invalidate(); | // Update the persistent message outside the transaction | // We want to know the message might have been delivered regardless | if (message.isPersistent()) | server.getPersistenceManager().update(message, null); | } | catch (JMSException e) | { | log.error("Error setting redelivered " + message, e); | } | } | To the setupMessageAcknowledgement() method instead (which is always invoked before delivering the message). But, this would obviously have a deterimental effect on performance since it would always update persistent messages with the redelivered status in the database regardless of whether it is was actually redelivered or not (if it doesn't get redelivered, i.e. it is ACKed/committed, it will be deleted so the early change in status is irrelevant). Do you want to try that patch?

I changed the High and Max Memory thresholds and now the messages are now longer stored in Hypersonic. This link describes this in detail http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfigMessageCache Thanks for the pointer to the FAQ Alex View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4096073#4096073 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4096073

[JBoss Portal] - Re: How to set and get Portal session

by saigon_man

Hi, Thanks for the response. The solution you provided only works with portlets within a portal project. If I have another portlet project deployed in jboss server (hot deploy) then this won't work (at least for me) What I would really like to find out is how to distribute a value/object to all of the portlets deployed within the portal (they can be hot deployed, meaning that they are seperate portlet projects) For example, I have a string value say String str = "my value". How do I distribute this value to all portlets from the portal scope when the portlets need this value without having the portlets to connect to database to get this value? Thanks, SGM View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4096072#4096072 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4096072

[JCA/JBoss] - Re: How to configure the minsize and maxsize of connectionpo

by liujw2001

Thank you for your help. I have another question. If a ManagedConnection is used by connection, Can this ManagedConnection be matched with a new connecion? If so, I have the following question: If one connection "A" get a ManagedConnection from pool which is used by another connection "B". After the first one "A" finished and want to close, dose it have some effection to connection "B"? for example, if "A" invokes "close()", the ManagedConnection will invoke the "cleanup()" function, does it effect the connection "B"? Is the ManagedConnection pushed into pool before the "A" finished ? The second question is why jobss service does't invoke "mathManagedConnection()" which is implemented in MyManagecConnectionFactory?

I had a look at the FAQ at http://wiki.jboss.org/wiki/Wiki.jsp?page=FAQJBossMQ but didn't find a solution to the DeliveryMode problem. Which post on the FAQ are you refering to.
