[JBoss jBPM] - Re: jBPM BPEL: Process Performance and Workload ?

by alex.guizar＠jboss.com

Hi Bertrand, I'll gladly give as much detail as I can, provided you publish the results of your investigation. Is that fair? Each client request creates a separate JMS session, yet they share a single connection per BPEL process. I am unfamiliar with the JBossMQ implementation details, but the JMS spec suggests the JMS connection encapsulates an open socket and sessions take turns to use the transport. Therefore, the impact of mantaining k-sessions is constant in resources (1 socket) and linear in time (k sessions trying to use the transport simultaneously). In practice, even tough you have k active sessions, only a fraction of them will be contending to use the transport. Some of them will be busy preparing the message or waiting for a response. In a jBPM BPEL process, message producers and consumers coexist in the web application where the web services are deployed. Hence, there is no reason for using a socket-based invocation layer. By using the in-JVM layer, sessions do not take turns to use the transport; they deposit messages on the queues directly. When you use a single queue, there will be significant overhead in filtering the messages. jBPM BPEL allows for assigning a separate queue to each partner link in order to alleviate the filtering load. Hope this helps. -Alex View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3976138#3976138 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3976138

[Beginners Corner] - Re: how does this work...

by kkarank

hi Peter ,let me explain the application name is FiboApp.ear and it contains FiboEJB.jar and FiboWeb.war - the META-INF of FiboApp.ear contains the application.xml file where there is a mapping from /fibo to FiboWeb.war this means that once that server comes to this application.xml file it will know what to do next. but my point is if i type http://localhost:8080/fibo how does the webserver know that it needs look inside the FiboApp.ear - what happens if i have say FiboApp2.ear , FiboApp3.ear and so on in my ...server/default/all directory ?

[EJB 3.0] - Re: Automatic Destroy State in Stateful Session Bean

by ALRubinger

You have an instance variable in your bean. By "Stateless", this means the container will not guarantee that the same instance will be returned to the same client on each invocation. At the end of the invocation, it's just returned to the pool. It's up to the developer to ensure the bean has no instance variables within that instance, or that all are reset to a common state, such that all instances in the pool can be considered "equal" and handed out to any client without evidence of that instance's history.

[JBoss Portal] - jboss portal 2.2.1 to 2.4 migration

by shagy69

Hi everybody, I used to have a portal application in portal 2.2.1 and I decide to migrate a few days ago. I read the documentation and change the xml descriptors like portlet-instances.xml, *-object.xml... my app was a portal with 4 pages, and now it seems to work quite well in the new 2.4 portal. The problem is that I have an applet which was displayed inside a portlet in the previous portal, and now I got a cannot render portlet saying that it is not founding the portlet instance. Portlet is loaded because the init() method got executed. In the jsp page where i put my applet I use to initialize the codebase param using "renderRequest.getAbsolutePath()" any idea of where the problem can be? Thanks in advance, any help is very appreciated. salva.

[Tomcat, HTTPD, Servlets & JSP] - web file cache, esi and more?

by meselfe

Does jboss have any sort of cache for static web files or are there any open source frameworks that can be used with jboss AS? Does JBoss AS support caching fragments of dynamic webpages using esi? Is the jboss web project still alive? How would I deploy static webcontent to JBoss AS without having to put it inside wars/ears?
