Hi all,
I have a small test process that uses persistency to store process and knowledge session data into a database.As part of my process workflow I have a Rule Task that pulls WorkflowProcessInstance from a knowledge session, and therefore I have to insert process instance into a ksession, as shown on picture:
http://community.jboss.org/servlet/JiveServlet/showImage/2-629611-17071/s... http://community.jboss.org/servlet/JiveServlet/downloadImage/2-629611-170...
Upon signalEvent(), process continues, calls rule task and runs to completion, and there is nothing wrong with that.
The problem is that my rule does not run:
rule "Test WorkflowProcessInstance existence" ruleflow-group "test"
when
$p : WorkflowProcessInstance()
then
System.out.println("Process instance exists!");
end
It is obvious that I'm missing WorkflowProcessInstance in a knowledge session, and therefore I've added it.
But now I'm getting the following exception upon calling UserTransaction.commit() method:
java.io.NotSerializableException: org.jbpm.workflow.instance.impl.WorkflowProcessInstanceImpl$1
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1164)
at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:330)
...
It seems to me it is a bug in jBPM5.1, could someone please check it?
If this is a bug, I can create a Jira issue, but since I'm a jBPM greenhorn, I'd rather like to check on forum first because maybe I'm missing something obvious ;)
I'm attaching a sample Eclipse project with both persistent and non-persistent scenario.
Thanks,
Miljenko

Hello I am new to JBoss and I am working in SpringSource Tool Suite (STS) 2.71. The application is built on the Spring framework. I have not modified any settings with the server since installing it. Perhaps I need to modify some settings? When trying to deploy my application to JBOSS 5.01, I am getting an error that I do not understand.
Here is my stack trace:
ERROR [AbstractKernelController] Error installing to Configured: name=jboss.web.deployment:war=/MVCProj1 state=Instantiated mode=Manual requiredState=Configured

[Performance Tuning] - Large number of threads/connections marked "keep alive"

"Large number of threads/connections marked "keep alive""

Hello
We're seeing an issue where the performance of our application would degrade over time, to the point where its unresponsive. Based on what I see, I think it might be related to how we're configuring keep-alive, and I'm wondering where I can find more information about configuring keep-alive in JBoss.
The symptoms:
- The application's performance would degrade over the day
- eventually we will get a message saying "all 200 threads are busy, please increase the maximum thread count"
- at this point, doing a thread dump (using "kill -3") shows many threads in the following state:
<blockquote>
"TP-Processor200" daemon prio=1 tid=0x0000002b31e372c0 nid=0x651a runnable [0x000000005408e000..0x000000005408ec30]

at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684)
at java.lang.Thread.run(Thread.java:595)
</blockquote>
- when I look at the "connection scoreboard" in the JBoss web console, I see 200 connections marked with a "K" for "keep alive", also these connections look like they've been around for a long time (around 7,000,000ms, which will be 2 hours), long after we've killed all the clientsd
Based on what I saw above and some googling, I'm thinking this might be related to how we're configuring keep alive. I haven't been able to go further than this, because I don't know much about JBoss configuration. Does anybody have any information about how keep alive is being configured in JBoss?
We are using JBoss version 4.0.5 GA
Thank you!

Trying to deploy an application that consists of a EAR/WAR/EJB module all separate. In the WAR a reference to the EJB3 SLSB is done like this:
