[Beginner's Corner] - Migration from Oracle Weblogic to JBoss Application Server

by Manoj Paul

Manoj Paul [https://community.jboss.org/people/manpaul] created the discussion "Migration from Oracle Weblogic to JBoss Application Server" To view the discussion, visit: https://community.jboss.org/message/826919#826919 -------------------------------------------------------------- Hi experts, Could someone please suggests/advice me on the challenges involve in migrating from Weblogic11 application server to JBoss7 application Server? The technologies involve in the project are: *JDK1.6 *JMS *EJB 3 *JRules *Sybase 12 DB and SQL Server 2005 DB One challenge I know is that we will need to convert the WebLogic EJB application to a JBoss EJB application, which involves changing the DDs. A WebLogic entity EJB application consists of the EJB DDs (ejb-jar.xml, weblogic-ejb-jar.xml, and weblogic-cmp-rdbms-jar.xml), and all the ejb-related java classes. The entity EJB deployment descriptors for the project are ejb-jar.xml, weblogic-ejb-jar.xml, and weblogic-cmp-rdbms-jar.xml. We will need to change all the instances (as in weblogic) into the corresponding deployment descriptors for JBoss(ejb-jar.xml, jboss.xml, and jbosscmp-jdbc.xml). Really appreciate a lots if someone can come up with valuable advices. Many Thanks -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/826919#826919] Start a new discussion in Beginner's Corner at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - jBPM designer present and future

by Guillermo L

Guillermo L [https://community.jboss.org/people/gmlopezdev] created the discussion "jBPM designer present and future" To view the discussion, visit: https://community.jboss.org/message/821964#821964 -------------------------------------------------------------- I've been trying to use jBPM and it is my belief that there's no engine without a designer. I've first tried to use the eclipse plugin for indigo release (SOA tools) and had several issues so I moved to the web designer which it appears to be the recommended way as per some post, articles, etc. The designer (v2.4) boundled with guvnor and jBPM installer (v5.4) has several issues right from the start. The first issue I've found out, was that after designing a very simple process and tried to execute it, I got an exception because the designer didn't set the "y" position of some elements. Currently there is no other published version of the web designer nor eclipse plugin and even I tried with other tools, at some point they do not quite integrate with jBPM finding myself after some time editing the BPMN2 tags which it is driving me crazy . I've seen that there is a 2.5 branch for the designer which I'm downloading and I´ll try to build it and deploy it to evaluate it. Is there anyone who can tell me whether 2.5 branch is really stable, and share experiences with either v2.4 or v2.5? What about the v6 currently under development? Will this designer be compatible with previous jBPM engine (i.e. v5.4)? The engine looks great, do not get me wrong, however I'm not quite sure/afraid about the maturity of v5.4 ecosystem (engine, repository, designer) and looking forward how is this going to scale and backward compatibility of new releases of the designer. I'll appreciate the feedback you may provide in order to clarify all this uncertainty I have. Thanks! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/821964#821964] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

You only need a recovery plugin if there is special recovery semantics for the resource adapter - look at the IronJacamar source code to get an idea of existing implementations. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/826142#826142] Start a new discussion in IronJacamar at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - Can guvnor maintain multiple versions of a BPMN definition with same name?

by mvermand

mvermand [https://community.jboss.org/people/mvermand] created the discussion "Can guvnor maintain multiple versions of a BPMN definition with same name?" To view the discussion, visit: https://community.jboss.org/message/826873#826873 -------------------------------------------------------------- Hi, In jBPM4.4 you can deploy a jPDL with the same name multiple times. The different versions automatically get a different version number and processInstances will keep using the version that was current when the processInstance started. You do not need to select specified Process Definitions upon engine startup. All is retrieved from the database as needed. In jBPM5.4 things seem to be different. If I am correct the Knowledge base needs to be filled at startup with all Process Definitions which are needed by any running process. If I need multiple versions of the same Process Definition in the kBase to complete process instances started with a different version, it seems I cannot use the same id for the different "versions" of the "same" process definition. Adding two process definitions with the same id but a different version number does not seem to work. 1) Am I right so far? If (1) == yes then 2) what it the use of the version number? 3) will everything work if I change the ProcessDefinitions with as id the original processDefinition id concattenated with the version number? 4) does Guvnor support automatic version management?: create BPMN with id a.b.c , start processInstance for this BPMN, change BPMN (keep id, but increment version), start second processInstance. ProcessInstance 1 will keep using version 1 of BPMN, ProcessInstance 2 will use the updated version of the BPMN If (4) == no then how does Guvnor handle changes to BPMN definitions? Are you supposed to upgrade all running versions of a Process Definition? Thanks a lot!

[Performance Tuning] - Remote EJB invocation performance

by Andrey Trakhirov

Andrey Trakhirov [https://community.jboss.org/people/andreytr] created the discussion "Remote EJB invocation performance" To view the discussion, visit: https://community.jboss.org/message/826592#826592 -------------------------------------------------------------- Hi there I have EJB Bean on JBoss 5 and remote client (webapp on tomcat 7). When I have 10-20 requests per second from Tomcat to JBoss EJB, the EJB request invocation time on tomcat takes about 100-150ms, on JBoss it takes about 100-140ms (same time). But when I have 200 requests per second from Tomcat to JBoss EJB, the request invocation time on tomcat takes abount 5000-6000ms, but on JBoss it takes only 1000-1200ms. Why so different results? Where is the limitation can be? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/826592#826592] Start a new discussion in Performance Tuning at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - Defining a List using ListDataType in web designer

I'm using JBPM 5.4, and in my project I have implemented a Custom Work Item, which takes a List as input; the item is defined through the Guvnor interface, and contains a ListDataType as a parameter. I have seen that, in the Web Designer interface, you can define the initial assignment value of the parameters of a task. Anyway, it is not very clear how to initialize the elements of a list. Can I insert a list of element writing them as a string, and using a separator, for example ';' ? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/825805#825805] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]
