Hi All I recently created two portlets that can share an object using JSR 286 events. One of the portlets is a source and the other is the target. But what I have observed is that the eventing works fine only when the portlets are deployed on the same page and not when they are placed on different pages. Can anyone please suggest how to implement Cross-Page eventing in JBoss EAP 4.3? I tried to do the same thing in WPS 6.1. Using the IBM wiring tool, it is possiblel to create cross-page events. Infact unlike JBoss, the within page eventing also requires that the wires be created using the administrative portlet.

[Performance Tuning] - VPS config tips

by mgvarley

Dear all - I am preparing to migrate my app (seam, mysql) after a long period of development onto production servers. I am renting a dedicated Centos server with an Intel Q660 chipset and 8gb memory. I want to be able to maximise performance whilst leaving the door open for future growth (i.e. the ability to add extra nodes with minimal downtime) and as such, I have setup a 4 VPS environment running on Xen partitioned as follows: = VPS 1 (Apache and Postfix email, <Proxy balancer://mycluster> load balancing to the JBoss servers,) = VPS 2 & 3: JBoss AS 5.0.1GA = VPS 4: MySQL This is all very new to me (Centos and administering JBoss) and so I would be very grateful for any suggestions relating to the config, specifically: = The recommended distribution of my 8gb across the VPS (e.g. a simple, 2,2,2,2 ?) = Recommendations for my JAVA_OPTS settings in server.xml = Any recommendations for config relating to my DataSource file = Should I be using mod_cluster instead of my current load balancing config = Anything I've (probably!) missed :o) Thanks in advance for any advice. mark View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4235248#4235248 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4235248

[Management, JMX/JBoss] - Re: Receiving notification from other MBeans

by dimitris＠jboss.org

Also the 'server' tag is at the wrong place. It should appear in the top. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4235246#4235246 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4235246

[Management, JMX/JBoss] - Re: Receiving notification from other MBeans

by dimitris＠jboss.org

Your subscription list is wrong, so try an mbean descriptor like this: | <mbean code="com.sample.jmx.StartupService" name="com.packtpub.jmx:service=StartupClass"> | <attribute name="Message">Hello World</attribute> | </mbean> | | <server> | <mbean code="jboss.example.NotificationListener" | name="jboss.example:name=NotificationListener"> | | <attribute name="SubscriptionList"> | <subscription-list> | <mbean name="com.packtpub.jmx:service=StartupClass"/> | </subscription-list> | </attribute> | </mbean> | </server> | Your StartupClass does not emit any custom notification to show in your listener. The only notification that should come up are the ones from the base ServiceMBeanSupport class.

[JBoss jBPM] - JBPM: Sub Process

by miggfried

Hi, i do not understand how to define sub processes. in JBPM My eample here is very simple. First is here my subprocess <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="subProcess"> <start-state name="start-state1"> </start-state> <end-state name="end-state1"></end-state> </process-definition> and here the main process which should be invoked the subProcess <process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="mainProcess"> <start-state name="start-state1"> </start-state> <process-state name="process-state1"> <sub-process name="subProcess"/> </process-state> <end-state name="end-state1"></end-state> </process-definition> I can do what i want, i always get the following exception (if the processInstance signals the current token, i.e. the start state). I test these process in the jsf console. Both processes are deployed!!!! org.jbpm.JbpmException: can't create a process instance when processDefinition is null it is very hard to find something about sub processes ,only some lines in the doku. But these are exactly the lines, i used for these test case. Can someone help me?
