--------------------------------------------------------------
Hi ...
We are using EAP5.1.1 (remoting-2-4-5.SP2) and experience a problem when using
SSL and there is a network hard failure (e.g. ethernet cable pulled), a socketWrite0() hangs
while holding a Messaging Post Office lock (readLock()) - this hangs JMS...(many threads
need PostOffice). Thread dump below. It is difficult to reproduce.
A Solaris 10 environment.
This problem has only been observed when SSL is used.
In our remoting-bisocket-service.xml file, we use:
<attribute isParam="true" name="writeTimeout">30000</attribute>
Have been told "writeTimeout" is broken when SSL is being used.
It has been suggested, for SSL, we change the configuration to turn on the check_connection parameter:
<attribute isParam="true" name="socket.check_connection">true</attribute>
But my concern is:
* results in an extra round-trip I/O (not good for a variety of reasons - throughput, remote clients with high latency connecitons, etc.).
* potential to hit other problems with check_connections enabled. e.g. found this:
https://community.jboss.org/message/369442#369442 https://community.jboss.org/message/369442
Has anyone experienced this problem and/or know a solution (other then using
"socket.check_connection") might be?
Searched and found a number of remoting issues on hard-network failure, but not this particular one...

[jBPM] - How to build package in Guvnor with JBPM process that use user data types ?

--------------------------------------------------------------
I have business process described in bpmn file. It has scriptTasks that use some project types.
<itemDefinition id="_stepItem" structureRef="project.model.Step" />
<itemDefinition id="_actionsItem" structureRef="java.util.Map" />
<process processType="Private" isExecutable="true" id="com.sample.id" name="EXAMPLE" tns:packageName="defaultPackage" tns:version="1" >
| | <extensionElements> |
| | <tns:import name="project.model.StepAction" /> |
| | <tns:import name="project.model.Step" /> |
| | </extensionElements> |
<!-- process variables -->
<property id="step" itemSubjectRef="_stepItem"/>
<property id="actions" itemSubjectRef="_actionsItem"/>
...
<scriptTask id="_2" name="1FakedStepAction" scriptFormat=" http://www.java.com/java http://www.java.com/java" >
<script>
try {
((StepAction)(actions.get("1StepAction"))).executeStepAction((Step)step); }
catch (Exception e) {
System.out.println("Exception 1StepAction: "+e);
}
</script>
</scriptTask>
...
In Java code I put
Map<String, Object> params = new HashMap<String, Object>();
params.put("step", <some real instance of Step>);
params.put("actions", <some actions map like 1StepAction -> real instance of StepAction>);
ksession.startProcess("com.sample.id", params)
It works fine when I put such file in class path and spring configuration uploads it from this file. I put it to Guvnor. And application successfully load such process from it and run.
But when I try to build package in Guvnor with such process it complains :
Unable to generate action invoker. project.model.Step cannot be resolved to a type
Process Compilation error project.model.Step cannot be resolved to a type
StepActioncannot be resolved to a type
So, how Guvnor can access to my types deployed in my project? Is it possible?

[jBPM] - java.lang.String cannot be cast to org.jbpm.task.utils.MarshalledContentWrapper

String respond = "SOME_VALUE";
Map result = new HashMap();
result.put("answer", respond);
ContentData contentData = null;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream out;
try {
out = new ObjectOutputStream(bos);
out.writeObject(result);
out.close();
contentData = new ContentData();
contentData.setContent(bos.toByteArray());
contentData.setAccessType(AccessType.Inline);
} catch (IOException ioe) {
ioe.printStackTrace();
}
localTaskService.complete(taskId, userName, contentData);
My process has a sequence of human tasks.
When I ran the code above, the first task executed fine, but the second task gives me:
java.lang.String cannot be cast to org.jbpm.task.utils.MarshalledContentWrapper
Any idea why it suddently doesn't work?

[jBPM] - How to properly use ContentMarshallerHelper for Human Task Output in JBPM5.3?

Hi,
I have one output on my human task, the output is of type String, and I map this output to one of the process variable.
The problem is, the mapped value becomes:
MarshalledContentWrapper{content=[B@342371e7, marshaller=org.drools.marshalling.impl.SerializablePlaceholderResolverStrategy, type=class java.lang.String}
how to make it resolve correctly to the String value?
here is my code
1. Map<String, Object> taskOutput = new HashMap<String, String>(1);
2. taskOutput.put("EvaluationResult",
3. "good");
4.
5. ContentData contentData = new ContentData();
6. contentData = ContentMarshallerHelper.marshal(taskOutput,
7. new ContentMarshallerContext(), null);
8.
9. taskClientHelper.completeTask(taskId.longValue(),
10. userId, contentData);
Any help is appreciated.
Best Regards,
Thomas Setiabudi
