[jBPM] New message: "JBPM subprocesses stuck on inactive-join"

by Michal Koziol

User development, A new message was posted in the thread "JBPM subprocesses stuck on inactive-join": http://community.jboss.org/message/528279#528279 Author : Michal Koziol Profile : http://community.jboss.org/people/mkoziol Message: -------------------------------------------------------------- Hi all, We have come across a strange problem with our jbpm process. It contains a fork and a join at the end. Both branches execute some subprocesses and when they finish, they meet in a join. Usually after the join, the main execution finishes, but sometimes (very very rarely - total of 3 cases) the processes wait in the join and the main execution never finishes. What we can see in the database in the "jbpm4_execution" table, is that the main process is in an "inactive-concurrent-root" state and the two subprocesses are in the "inactive-join" state. Has anybody seen something like that? We are just curious if we are doing something wrong or is it a rare bug? There is a workaround for that, just do this: +executionService.endProcessInstance(pid, state)+ but we would rather not see it in the database at all. Any help would be appreciated. We are using JBPM v4.1, Here is our jbpm process in xml: <?xml version="1.0" encoding="UTF-8"?> <process name="proc1" xmlns="http://jbpm.org/4.0/jpdl"> <start g="246,25,48,48" name="start"> <transition g="-68,-18" name="to validation" to="validation"/> </start> <decision g="245,115,48,48" name="validation"> <handler class="x.validation.ValidationParameters" /> <transition g="-48,-18" name="error" to="error"/> <transition g="-50,-6" name="to fork" to="fork"/> </decision> <end-error g="60,115,48,48" name="error"/> <fork g="244,194,48,48" name="fork"> <on event="end" continue="exclusive"> </on> <transition g="3,-18" name="to create cases" to="create cases"/> <transition g="-72,-18" name="to search bets" to="search bets"/> </fork> <sub-process g="127,278,92,52" name="search bets" outcome="${result.outcome}" sub-process-key="SearchBets"> <parameter-in expr="${owner}" subvar="owner"/> <parameter-in expr="${eventId}" subvar="eventId"/> <parameter-in expr="${timestamp}" subvar="timestamp"/> <parameter-out subvar="result" var="searchBetsResult"/> <transition g="-35,-18" name="to join" to="join"/> </sub-process> <sub-process g="302,280,92,52" name="create cases" sub-process-key="CreateCases"> <parameter-in expr="${owner}" subvar="owner"/> <parameter-in expr="${eventId}" subvar="eventId"/> <parameter-in expr="${timestamp}" subvar="timestamp"/> <parameter-in expr="${ticket}" subvar="ticket"/> <parameter-in expr="${roleList}" subvar="roleList"/> <transition g="11,-14" name="to join" to="join"/> </sub-process> <join g="235,386,48,48" multiplicity="2" name="join"> <transition name="to decision" to="decision" g="-56,-18"/> </join> <end g="239,567,48,48" name="end"/> <end-error name="errorproc1" g="107,486,48,48"/> <decision name="decision" g="237,483,48,48"> <handler class="x.validation.ValidationEndProcess" /> <transition name="to errorproc1" to="errorproc1" g="-32,-14"/> <transition name="to end" to="end" g="-36,-18"/> </decision> </process> -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/528279#528279

[JBoss Cache] New message: "is this a good use for jboss cache"

by robert walker

User development, A new message was posted in the thread "is this a good use for jboss cache": http://community.jboss.org/message/528265#528265 Author : robert walker Profile : http://community.jboss.org/people/robertwalker Message: -------------------------------------------------------------- I have a setup where we have 8 jboss clusters/nodes, but they are not setup to communicate with each other, just more of a load balancing setup with apache. I have a pojo in my webapp that keeps track of each logged on user FOR THAT NODE, i.e. for the cluster the user is logged on to but when a user activates a link on the client "Show logged on users" I want to show ALL the users from each of the 8 nodes, so really the pojo from each node concatenated, showing my a summation of all the pojo's lists. I was thinking the jboss cache could help me here any thoughts, I am really green to this and reading about it now over on http://www.jboss.org/file-access/default/members/jbosscache/freezone/docs... thanks -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/528265#528265

by jaikiran pai

User development, A new message was posted in the thread "EJB3 Session Bean Container error": http://community.jboss.org/message/528251#528251 Author : jaikiran pai Profile : http://community.jboss.org/people/jaikiran Message: -------------------------------------------------------------- Looking at the stacktrace, its a servlet calling bean1 which then calls bean2. And the system is a MacOS with Apple JVM. I don't see a reason why this would fail. Can you attach application(s) which can reproduce this issue? By the way, have you patched the server with the latest EJB3 plugin or is it just a clean AS 5.1.0? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/528251#528251

User development, A new message was posted in the thread "How to make some MDB singleton": http://community.jboss.org/message/528247#528247 Author : mariqn nenchev Profile : http://community.jboss.org/people/mnenchev Message: -------------------------------------------------------------- Hi, i know that this is totally against the idea of mdbs, but my mdb will update memcache so if messages come to fast the AS will create more than one mdb and they will try to update memcache simultaneously and this will blow. If i make my mdb singleton this will not happen, the mdb will update the memcache sequentially(i think). And although it is too frequently it will be sequentially, so i think it will work. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/528247#528247
