[jBPM] New message: "A few questions about jBPM"

by Antoine Pierronnet

User development, A new message was posted in the thread "A few questions about jBPM": http://community.jboss.org/message/529130#529130 Author : Antoine Pierronnet Profile : http://community.jboss.org/people/Kamoulox Message: -------------------------------------------------------------- I'm exploring jBPM and other BPM tools in order to choose one, I have some questions : - what about BPEL compliance? - how are packaged designed applications? - is there any standard connector provided (database, BI tools, etc) - Are EJBs supported? - is there any JAAS support? - Any JMX plug? - Any versionning system? (something in the webapp that would help manage process versions?) - Is that possible to trigger a process from an external program like a scheduler? - Is remote deployment possible? - What are the supported Web servers? - Are the processes compatible with other BPM engines? - Compatible OS? - Support price ? - What about error management? (Exceptions handling, etc) - High availability? - How configurable are user dashboards? - How are users/roles managed? I know that's a lot... Thanks! -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529130#529130

[JBoss Tools] New message: "Re: JBossTools-3.0.3.GA On Eclipse Ganymede"

by Salim OFLAZ

User development, A new message was posted in the thread "JBossTools-3.0.3.GA On Eclipse Ganymede": http://community.jboss.org/message/529127#529127 Author : Salim OFLAZ Profile : http://community.jboss.org/people/salimoflaz Message: -------------------------------------------------------------- Hi Dennis, I finally achieved to generate some files with Jboss Tools in eclipse. I read the database user guide you mentioned in your post and added some parameters to the command used to start database in server mode. like this one; java -cp ~/lib/hsqldb/lib/hsqldb.jar org.hsqldb.Server -database.0 file:test -dbname.0 ta to give database alias and pyhsical files used for it. I am using Open SUSE 10.3 LINUX operating system and eclipse ganymede 3.4.2 and Jboss Tools 3.0.3 GA and I discovered that the database table names should be in uppercase, maybe this holds for other database objects such as Foreign Keys, Primary Keys and Views. Otherwise it's not generating anything. In addition I had to switch to Hibernate perspective and changed Hibernate configuration such as database connection and dialect, added hsqldb.jar to classpath, changed type to core. After all it worked. But I spent a lot of time. Hope this helps somebody else in the future who plan to use HSQLDB and Jboss Tools. Thank you for your posts. Best Regards, Salim OFLAZ -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529127#529127

User development, A new message was posted in the thread "BPMN 2.0 Modellers / Designers": http://community.jboss.org/message/529126#529126 Author : Sebastian Schneider Profile : http://community.jboss.org/people/sebastian.s Message: -------------------------------------------------------------- Hello Mauricio, I tried the Drools Modeler and I was able to switch to the BPMN-skin. But I could not find a way to read a .bpmn-file with the modeler. Is this feature in Drools 5.0 or do I need to use the trunk to have this functionality? Joram: How are you creating and generating the process definitions for the implementation of BPMN-2.0? Thanks for any hints Sebastian -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529126#529126

[JBoss Web Services] New message: "Re: Occasional exceptions out of SOAPAddressingPropertiesImpl.writeHeaders"

by Andrew Dinn

User development, A new message was posted in the thread "Occasional exceptions out of SOAPAddressingPropertiesImpl.writeHeaders": http://community.jboss.org/message/529124#529124 Author : Andrew Dinn Profile : http://community.jboss.org/people/adinn Message: -------------------------------------------------------------- > frapaa wrote: > > Thanks for the quick reply! > > I am running on JBoss 5.1.0 GA (bundled with Mobicents 1.2), but I don't know if I should start debugging that platform, hehe.. :-) > > Could the issue be that one of the classes in my application is holding on to a reference to this class that failed to undeploy/deploy? Well, 5.1.0.GA may be worth trying to sort out. However,. hot deploy is a difficult thing to be get right because there are lots of places where something could be holding on to classes it should not be referring to -- that might be JBoss or it might be your code or it might be both. Whether the problem shows or not depends in part upon the order of classloading so probelms may linger for a while even when you think it is working. Are you deploying several artefacts and then only updating one? This can cause problems if you don't declare dependencies between your deployments. If there are dependencies then declare them so that the AS will undeploy the whole set. If not then you may have uncovered a bug in the AS or WS code. Since we don't offer any guarantees that hot deploy will work any problem you find will be a low priority for fixing -- hot deploy is merely a 'nice to have' for development, it's not somehting anyone should rely on in production. If you really want to find out what is wrong/fix it you'll need to rev up your debugger. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529124#529124

User development, A new message was posted in the thread "Exception handling in JBPM4 ?": http://community.jboss.org/message/529121#529121 Author : Atul Joshi Profile : http://community.jboss.org/people/AtulJoshi Message: -------------------------------------------------------------- I have changed the process design as follows.1. Instead of System Activity call Sub Process, name as "Sub_process_catch_Exception" , 2. In this sub process Instead of calling the system activity add Decision activity (Implement Business Logic in decision instead of SystemActiviy), 3. If Decision activity executed successfully then Sub Process will end Else Forward control to next activity (i.e. State Node.)End if1. Trigger Wait (State Node) activity after resolving the exception by using the execution Id of the activity Please refer the attached code.** *Advantage:*1. I am able to implement *Retry, Skip, Max No. of Retries and timeout* for all JAVA activities present in my Workflow design, using this common solution, *Disadvantage:*1. I have almost completed my workflow design, if I want to implement Exception Handling I need to change my design *from scratch*, Suggest me if i can do better to handle exceptions in JBPM4? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/529121#529121
