Re: [jboss-user] [jBPM] - in jbpm 4.3, timer not firing to leave its state node.

To view the discussion, visit: http://community.jboss.org/message/554661#554661 -------------------------------------------------------------- Hi HuiSheng: The following is my jbpm.cfg.xml for jbpm 4.3: <?xml version="1.0" encoding="UTF-8"?> <jbpm-configuration> <import resource="jbpm.default.cfg.xml" /> <import resource="jbpm.jpdl.cfg.xml" /> <import resource="jbpm.identity.cfg.xml" /> <import resource="jbpm.tx.hibernate.cfg.xml" /> <import resource="jbpm.variable.types.xml" /> <import resource="jbpm.jobexecutor.cfg.xml" /> <import resource="jbpm.businesscalendar.cfg.xml" /> <import resource="jbpm.jpdl.cfg.xml" /> <import resource="jbpm.mail.templates.examples.xml" /> </jbpm-configuration> The following is the sequence of our test activities : (1) deploy the .jpdl.xml which contains the state node associated with a timer : <?xml version="1.0" encoding="UTF-8"?> <process name="test_Timer_1"> <start g="270,34,54,49" name="start1"> <transition to="generate-file"/> </start> <state g="222,123,147,40" name="generate-file"> <transition g="-71,-15" name="timeout" to="remove-file"> <timer duedate="10 seconds"/> </transition> </state> <state g="222,214,147,40" name="remove-file"> <transition to="end1"/> </state> <end g="272,302,48,48" name="end1"></end> </process> (2) run the start process instance: (3) so we assume that the token entered the "generate-file" node and waited more that 10 seconds, but we still only saw 2 entries in the jpbm4_execution table. (4) then we deploy one more time, and now we saw the "remove-file" activity entry created in the jpbm4_execution table. There must be something wrong, but we can not figure out from the jbpm cfg related xml files. Thanks for your help again. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/554661#554661] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [jBPM] - [Q] JBPM 4.4 JbpmException

Re: [jboss-user] [JBoss AOP] - Dynamic AOP application, not able to redeploy the aspects at runtime

I was deploying the session bean as a class that needs to be aspectized. i was including this session bean class in the *-aop.xml. Can this be done? I am making the changes in the methods in the Session bean. The methods have print statements. I am changing these print statements and redeploying the jar. These methods are deployed in the aopdynclasses folder as aspectised classes (even after redeployment). And these changes in the print statements are the changes that i want to see when the jar is redeployed. The interceptor class is being deployed as a jar with the structure / Interceptor.class META-INF/ MANIFEST.MF >From this interceptor i am calling the session bean methods.

Re: [jboss-user] [jBPM] - Errors instaling JBPM 4.3 in JBoss 4.2.3

Change <jbpm-distro-home>\install\src\jboss\config\deploy\jbpm\jbpm-destinations-service.xml to fix for 4.2.3.GA: <mbean code="org.jboss.mq.server.jmx.Queue" name="jboss.mq.destination:service=Queue,name=JbpmCommandQueue"> <depends optional-attribute-name="DestinationManager"> jboss.mq:service=DestinationManager </depends> </mbean> And run the ant target "install.jbpm.into.jboss" again. Optionally edit the file directly on jBOSS at <jboss-home>\server\default\deploy\jbpm\jbpm-destinations-service.xml and insert the same modifications. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/554656#554656] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [EJB 3.0] - Problem running ejb3 tutorial examples

jaikiran pai [http://community.jboss.org/people/jaikiran] replied to the discussion "Problem running ejb3 tutorial examples" To view the discussion, visit: http://community.jboss.org/message/554655#554655 -------------------------------------------------------------- I just went through that stacktrace and then mapped it to the code and this definitely has to do with where the jar containing some classes is being picked up from. That codebase location contains a folder named something like "xxx and yyy" which causes this issue. Please post the output of: echo %JAVA_HOME% echo %JBOSS_HOME% and java -version from the command prompt from where you are running the tutorials. If that doesn't give us enough hints, then I have one other thing in mind, but let's first rule out the obvious ones. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/554655#554655] Start a new discussion in EJB 3.0 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [Performance Tuning] - Variation in Max Heap size

by Peter Johnson

Peter Johnson [http://community.jboss.org/people/peterj] replied to the discussion "Variation in Max Heap size" To view the discussion, visit: http://community.jboss.org/message/554644#554644 -------------------------------------------------------------- An appplication server will always have remote objects, whether you use them directly or not. By default, the RMI code will perform a major collection every minute. The settings in the run scripts change this to every hour. Why every hour? Why not every 30 minutes, or every 24 hours or every week? Where did the recommendation of one hour come from, and what is it based on? At the very first JBoss World in 2005 I presented a talk on JBoss AS performance tuning, using the SpecJAppServer benchmark to do the analysis. A typical benchmark run included starting the app server, trying a web page or two to make certain things were running correctly, running the benchmark, and then shutting the app server down. The benchmark runs for about 20 minutes. We didn't want the RMI collector to fire off a major collection during the benchmark so we changed the delay to be long enough that it would not interfere with the benchmark - 60 minutes. After that talk, the 60 minute RMI setting appreared in the run scripts. The 60 minutes suited out benchmark run - it practically guaranteed that there would be no RMI collection during the time the app server was running. So how long do you typically run the app server before restarting it? A week? A month? Longer? Well, that is what you should base the RMI GC settings on, not an arbitrary recommendation of 60 minutes. Moral of the story: find out why someone recommends a certain setting, then adjust the setting based on your environment and circumstances. Oh, and by the way, the RMI thread that handles the GC uses System.gc(), so setting DisableExplicitGC will prevent the RMI GC from taking place. However, it is still a good idea to set sun.rmi.dgc.client.gcInterval and sun.rmi.dgc.server.gcInterval to a high value to prevent the RMI thread (the one that sleeps for the time interval and then calls Syste,.gc()) from running. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/554644#554644] Start a new discussion in Performance Tuning at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
