[jBPM Users] - Re: Can JBPM manages more than one datasource?
by jbosspnet
I try to change approach.
Suppose I do not install JBPM in JBOSS (so I do not have the folder "jbpm" under the Jboss deploy directory but more important I have no dependicies with a datasource) and all the JBPM clients are web applications that can use a different datasource, deployed in JBOSS by the usual *-ds.xml file.
If now I deploy an ear file (to enclose both web application and a custom version of jbpm-enterprise that not only refers to the JNDI name defined in the datasource already deployed but also allows the access to the JBPM EJBs (namely CommandServiceBean, TimerServiceBean, etc.)), with the correct JBPM configuration (jbpm.cfg.xml and hibernate.cfg.xml file, the last refers to the same JNDI datasource name), every process that I will deploy (by jbpmContext.deployProcessDefinition method) or every process instance that I will create (processDefinitio.createProcessInstance method) in the web application, will refer to the correct JBPM database.
Is it correct?
Are there any problems about this approach (for example the deploy of another ear, the access to the JBPM EJBs or something else)?
Regards.

[jBPM Users] - Re: JBPM 4.0 HistoryEvent, HistorySession
by tcr
Addition:
I wasn't able to find a binding for HistorySessionChain. I created one (see below).
Maybe some hints for all who want to add a custom historySession....
Steps:
- Create your custom history Session (implement org.jbpm.pvm.internal.history.HistorySession)
- Create the binding class for the custom history session (you can copy the binding from historySession and adjust tag and class)
- Create the binding class for the historySessionChain (see below)
- Add both bindings to jbpm.wire.bindings.xml
- Change your configuration by adding the chain-tag including the actual history sessions.
Last problem I have:
Can anyone see an option to get the of the execution memeber of the history-events in the custom event session without changing the code?
Regards
Torsten
CustomHistorySession.java
package com.test;
|
| public class CustomHistorySession implements HistorySession {
| public void process(HistoryEvent historyEvent) {
| // Do your custom work here
| }
| }
CustomHistorySessionBinding.java
| package com.test;
| public class CustomHistorySessionBinding extends WireDescriptorBinding {
|
| public CustomHistorySessionBinding() {
| super("custom-history-session");
| }
|
| public Object parse(Element element, Parse parse, Parser parser) {
| return new ObjectDescriptor(CustomHistorySession.class);
| }
| }
HistorySessionChainBinding.java (copy and modify from deployer-manager)
| package com.test;
|
| public class HistorySessionChainBinding extends WireDescriptorBinding {
|
| private static final String HISTORY_SESSION_CHAIN_TAG = "history-session-chain";
|
| public HistorySessionChainBinding() {
| super(HISTORY_SESSION_CHAIN_TAG);
| }
|
| public Object parse(Element element, Parse parse, Parser parser) {
| ObjectDescriptor objectDescriptor = new ObjectDescriptor(HistorySessionChain.class);
|
| ListBinding listBinding = new ListBinding();
| ListDescriptor listDescriptor = (ListDescriptor) listBinding.parse(element, parse, parser);
| objectDescriptor.addInjection("delegates", listDescriptor);
|
| return objectDescriptor;
| }
| }
jbpm.wire.bindings.xml
| <binding class="org.jbpm.pvm.internal.wire.binding.HistorySessionBinding" />

[jBPM Users] - [jBPM Bpel] Example in the userguide and the actual example
by nazarfm
The Bpel 'hello' example in the user-guide has one inconsistency with the actual example project. The guide gives the following:
<assign name="ComposeGreeting" validate="no">
| <documentation>compose a greeting phrase</documentation>
| <copy>
| <from>concat('Hello, ', $request.name, '!')</from>
| <to part="greeting" variable="response" />
| </copy>
| </assign>
The highlighted value is what Netbeans bpel designer will also produce. However, this does not work in jBPM bpel. Rather, the given hello example project changes the highlighted text into:
<from expression="concat('Hello, ', bpel:getVariableData('request', 'name'), '!')" />
And this works. Is there something I'm not seeing here? I figure the first one should also work but so far no luck. No errors are reported, it just hangs. Anyone else had this experience?
Versions:
jBPM bpel 1.1.1
Jboss AS 4.2.3.GA

so it was a user problem....
and since the birt reporting is installed in /data/birt it took so long to find the actual culprits:
