[Design of JCA on JBoss] - Re: Datasources not parsing jboss.server.data.dir

I just tried it. It works for String-based properties. But not int, for example. Since unmarshalling/JAXB converts string values to the target Java types in metadata. And then the builder is called. One way to workaround this could be to make all the properties in the metadata Strings. It seems like whatever type of the property is the value is converted to String anyway during the service building. Also other uses of the unmarshalled metadata will have to be checked to make sure the system properties are substituted, e.g. when creating object names.

[Design of JBoss Build System] - Re: how to change classpath

by akostadinov

I see how the scope works. As well I realized that I don't need to have these libraries taken from outside but need these built now. I'll start another thread about it. Thanks for the help!

[Design of JBoss jBPM] - Re: Pass process instance key to sub process

by jbarrez

I have had the same problem in the past and I use <process-state name="subFlow" > | <sub-process name="theSubFlow" binding="late" /> | <variable name="id" mapped-name="subflow.id" /> | </process-state> I don't see the benefit of having a specialized construct for it.

[Design of JBoss jBPM] - Re: Pass process instance key to sub process

by camunda

Good point! I think the functionality is quite a good idea... Maybe we should do it somehow similar to the variables given to a sub-process? But makes things more complex, so maybe not... (Would be somehow like this: | <process-state name="start-child-process"> | <sub-process name="child-process" binding="late"/> | <variable access="read,write" name="variable1" mapped-name="dsadsad" /> | <key access="read,write"/> | </process-state> | ) And what crossed my mind, should we consider other use cases like "I want to pass the key to the sub-process, but not as key, but as variable x"? My feeling says, better not, just keep it simple... But currently I don't have a concrete use case, so these are just thoughts....

[Design of JBoss jBPM] - Pass process instance key to sub process

by mimra

Hi I would like to be able to pass the key of a (parent) process instance to a child process instance created using: | <process-state name="start-child-process"> | <sub-process name="child-process" binding="late"/> | </process-state> | I have searched the docs and the net and asked a forum question: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=142969 It seems to me there is no easy way (if any) of doing this, so I might add this. I would like some input on my thought. I am thinking about adding a attribute to the sub-process tag to specify if the child process should be given the parent key. Something like: | <process-state name="start-child-process"> | <sub-process name="child-process" inheritParentKey="true" binding="late"/> | </process-state> | Then I would make the change in the org.jbpm.graph.node.ProcessState. Any comments on this? /Michael View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4178762#4178762 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4178762

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Why do messages destined for paging not get assigned mes

by timfox

Actually I spotted a race condition in it, so I've temporarily synchronized the whole thing for now for correctness (at expense of perf).

I wouldn't worry about it - you only have a synchronized hit once every Integer.MAX_VALUE ids so it is insignificant.

[Design of JBoss jBPM] - Initialise thread context classloader

by camunda

Hi. I am working on https://jira.jboss.org/jira/browse/JBPM-1448 (jBPM does not initialize thread context classloader). First of all, why I want to do this: This enables you to put Interfaces or other stuff used in your action classes in the par, so they end up in the database. Because the ProcessClassLoader will become ContextClassLoader it is used to load everything correctly... But this is only half the way I want to go. Image you put jbpm in your app-server (or ESB) once, but have different applications (ear, esb, ...) using it. Now I write an own small MBean, which is a registry where processes register which class loaders are responsible for "their" action classes. My own ProcessClassLoader now also looks in this registry and by doing so, it can even load action classes or other stuff correctly from the right EAR, even if a process was maybe started by the web-console, not knowing the ear... But more on this idea later. Back to setting the ContextClassLoader. My approach to implement it is adding this code | ClassLoader oldCl = Thread.currentThread().getContextClassLoader(); | try { | Thread.currentThread().setContextClassLoader( | ClassLoaderUtil.getProcessClassLoader(processDefinition)); | | .... existing code ... | } | finally { | Thread.currentThread().setContextClassLoader(oldCl); | } | to the following methods: - Action.execute - Decision.execute - TaskController.initializeVariables - TaskController.submitParameters - AssignmentHandler.performAssignmentDelegation On all these places I have the ProcessDefinition on hand, so it is possible to do... These are all places I found where the ProcessClassLoader is used and all Delegation use cases I remembered. So it is not too much work to do and consistent overall in jBPM (not like the proposed workaround to build an own base action class where the context class loader is set). What do you guys think?

[Design of JBoss jBPM] - Re: gwt-console in distribution

by heiko.braun＠jboss.com

Yes, the gwt:compile take some time. But it's only required for web mode. So if you want to run the console in hosted mode a simple 'mvn compile gwt:gwt' is sufficient. This reduces the turnaround time a lot. Add a "mvn -o" to it and becomes a pleasure to work with.
