[JBoss Remoting] New message: "Re: Client hangs when get JMS connection factory"

Can you elaborate? > > -Ron Ron, please refer to this link: https://jira.jboss.org/jira/browse/JBREM-1169. Actually, you had already commented on this issue in the JBREM-1169 In our application, there are a lot of Message listeners running on the client side, these message listeners will receive messages from queue/topic deployed in JBoss Messaging. If we set the timeout value to a non-zero value, and if there is no message in topic/queue in server side, then the remote client (message listener) won't receive any message, that mean the connection between client and server is idle, if the idle duration exceeds the non-zero "timeout" value, then the JBM will forcibly close the connection, so the remoting client won't receive any subsequent messages from server any more...... -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/520972#520972

[jBPM] New message: "Re: Problem Signaling a Waiting Execution"

by Ronald van Kuijk

User development, A new message was posted in the thread "Problem Signaling a Waiting Execution": http://community.jboss.org/message/521192#521192 Author : Ronald van Kuijk Profile : http://community.jboss.org/people/kukeltje Message: -------------------------------------------------------------- Andy, No sweat, and I certainly did not want to offend you in any way. It's just that I've never seen anyone (try to) use jBPM like this. Regarding executions/processinstances et al. Executions kind of travel trough the process like tokens in petri nets (in jBPM 3 they were called tokens). If there are no forks etc, there is only one root execution that at the same time is the equivalent of the process instance. Activities are what is done when the execution reaches a node. hope this helps (a little) -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521192#521192

[jBPM] New message: "Re: Problem Signaling a Waiting Execution"

by Andy Barreras

User development, A new message was posted in the thread "Problem Signaling a Waiting Execution": http://community.jboss.org/message/521185#521185 Author : Andy Barreras Profile : http://community.jboss.org/people/FlyNavy Message: -------------------------------------------------------------- Thanks for all of the input folks. Ronald, just to clarify I have read the jBPM documentation - over and over and this is my first exposure to BPM technology, at least from a developer's point of view (I did the Systems Engineering in a project that used Oracle's BPM technology). I suppose you are correct; BPM does not jive with my notion I have of a traditional "workflow". Given my example, I do not understand how jBPM is supposed to work. For example, why does jBPM equate an Execution to a Process Instance? To me, a process instance should be a run of the entire Process Definition, i.e. "workflow" (all the "actvities" or "steps") and an Execution is simply the node ("activity" or "step") that is currently being executed. The jBPM documentation (as well as you guys) reference external Java classes that "control" the workflow execution outside of the listeners. That's probably where I made my mistake. I think you guys are correct; I need to back up and re-think my strategy. Again, thanks to evryone for the help. Much approeciated. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521185#521185

[JBoss Microcontainer] New message: "Re: Info required about jboss-classloading.xml"

by null null

User development, A new message was posted in the thread "Info required about jboss-classloading.xml": http://community.jboss.org/message/521184#521184 Author : null null Profile : http://community.jboss.org/people/deanhiller Message: -------------------------------------------------------------- does the old method(jboss-web.xml and jboss-app.xml) work for this use case... war1 and war2 use version 2 xx.jar (all in deploy directory) war1 uses version 2 of yy.jar (all in deploy directory) war2 uses version 1 of yy.jar (all in deploy directory) I was under the impression OSGi supports this while old jboss unified classloader doesn't...in face, version2 of yy.jar will override(be loaded first) version 1 yy.jar(or vice versa). Don't I have to use the new classloading.xml way and where are the details of that(xsd and location of file...i assume META-INF in jar files and WEB-INF in war files????) thanks, Dean -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521184#521184

I would definitely check out Seam or Weld as an extension to JSF. You should not use JSP for new development. Whether you use JSF 1.2 or JSF 2.0, you should use Facelets instead of JSP. With JSF 2.0, Facelets is built-in and some of the new features don't work with JSP.

There is still a lot of Struts development on older applications. If you are still in development and you can wait for the AS 6 final release then I would encourage you to develop against AS 6 milestones. That allows you to use all the new features of JSF2. Of course, that entails some risk on your part because we can't guarantee when a production-quality AS 6 release will happen. Brian could probably give you an educated guess, but it would still be a guess and I'm not sure if he's even willing to go there.

What i am really looking for is some suggestions to how to build my application. Should i start with "seam" framwork or any other framework out there or just use jboss as is (as i did till now in the company i work for, my components where a small part in a huge system built terribly wrong ). What i need is, of course, a connection between the JSP input fields to the database and have some logic between them. JBOSS (or java ee) is a big thing and i am not sure i need to learn or use everything from the start. What keywords for the jboss parts should i start reading about to get me in the right direction? Thanks again. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521165#521165
