--------------------------------------------------------------
To start, my system is:
Windows 7 (64bit)
Eclipse Indigo (Build id: 20110916-0149)
JBossASTools (Version: 2.3.0.v20111213-1423-H61-M5)
JBoss AS 7.1
I have had this configuration up and running for over a month. Suddenly starting yesterday I have been unable to start up my system in debug. I have made no significant changes to my system (save for the installation of TOAD but it was still working for a while after that was installed). It will start fine in run mode and it starts in < 10 seconds. When I start using the debugger, it takes > 1:30 and then fails in the end. The last couple of lines from server.log are:
10:11:11,188 INFO [org.jboss.web] (MSC service thread 1-2) JBAS018210: Registering web context: /speed2

I have attached a zip containing server.log files from starting with a plain run and starting in debug to show the success/failure. Also, I bumped my logging up to DEBUG to give a little more information.
Any assistance getting my debugging back on line sure would be appreciated!

Hi,
I create for my process a task form by guvnor/ designer. When I run my process using the local port http://localhost:8080/jbpm-console/ http://localhost:8080/jbpm-console/ everything works fine:
https://community.jboss.org/servlet/JiveServlet/showImage/2-725743-18261/... https://community.jboss.org/servlet/JiveServlet/downloadImage/2-725743-18...
But when I try to run the process on my external test server I got a strange behaviour:
* I get asked for credentials again

Any suggestions?

[Javassist] - How to manage instrumentation in application deployed on JBoss?

Hello everybody,
I'm trying to instrument classes in JBoss Enterprise application on JBoss EA5.0
Using this code:
| | public byte[] transform(ClassLoader loader, |
| | String className, |
| | Class classBeingRedefined, |
| | ProtectionDomain protectionDomain, |
| | byte[] classfileBuffer) throws IllegalClassFormatException { |
| | // The class name contains slashes instead of periods, so use transform those to |
| | // dots for readability within the trace |
| | String dotClassName = className.replace('/', '.'); |
| | if (className.startsWith("$")) { |
| | return null; |
| | } |
| | // Only instrument a class once |
| | if (instrumentedClasses.contains(className)) { |
| | return null; |
| | } |
| | instrumentedClasses.add(className); |
| | // Skip in the list of class prefixes to skip |
| | for (MethodSelector classToSkip : classesToSkip) { |
| | if (dotClassName.startsWith(classToSkip.getPackageName())) { |
| | return null; |
| | } |
| | } |
| | if (logger.isInfoEnabled()) { |
| | logger.info("Checking class: " + className); |
| | } |
| | |
| | try { |
| | classPool.insertClassPath(new ByteArrayClassPath(className, classfileBuffer)); |
| // | classPool.insertClassPath(new ClassClassPath(this.getClass())); |
| | |
| // | classPool.insertClassPath(new ClassClassPath(classBeingRedefined.getClass())); |
| | *CtClass cc = classPool.get(dotClassName);* |
| // | CtClass cc = classPool.makeClass(new ByteArrayInputStream(classfileBuffer)); | |
//
In bold line where exception is raised.
I suppose that arror is related to specific class loader used for load class.
The question is: how to manage classes independently from class loader used? Is there a way to manage all possible case when working on JBoss?
Thank you
Alessandro

[jBPM] - Persistence issue running jBPM 5.3 gwt-console-server on JBoss AS 7.1.1

Hi all,
Hopefully this is an easy issue, but I am trying to deploy gwt-console-server in JBoss AS 7.1.1 and I am getting the following error in the log (below) due to JPA it seems. I'm guessing that the duplicate import info on the first two lines is causing the failure, but I do not know why that is occurring. Any guesses?
Thanks,
Brian

[jBPM] - How to define result mapping or exit action that saves task owner

"How to define result mapping or exit action that saves task owner"

Hi,
This should be simple for any non-novice, it was suggested before however without an example.
So I have a process variable and I want a particular task to store its owner into that variable (say its name is "task2owner"). Is there an expression for that, for example:
task2owner=#{taskOwner}
So if there is a standard expression for the task owner (the above is just a guess at what it might be) then this result mapping would allow subsequent tasks to determine who owned (and completed) task2.
Failing that, I could try defining an on exit action, using kcontext I can get the node instance which I think has a one-to-one correspondence to the task, however the node instance does not seem to have an attribute that explicitly identifies the owner. Perhaps the owner is a variable?
Any suggestion would be greatly appreciated.
Thanks!

[JBoss Messaging] - How to list or monitor messages in a Queue which is already under use

"How to list or monitor messages in a Queue which is already under use"

--------------------------------------------------------------
I have a requirement to monitor a JBoss messaging queue, where users should be able to delete posted messages dynamically. The application has a MDPOJO registered and is up and running at server start up.
My requirement is, users should be able to delete a posted message any time he wishes. I tried below proto codes :
*Option1*
public void listAllJMS_Messages()
{
try {
ObjectName objectName=new ObjectName("jboss.messaging.destination:name=XXX,service=Queue");
List ls = (List) server.invoke(objectName, "listMessages" , null, null);
List<javax.jms.Message> messages=(List<javax.jms.Message>)server.invoke(objectName, "listAllMessages" , null, null);
int count=0;
for(javax.jms.Message msg : messages) {
System.out.println((++count)+"t"+msg.getJMSMessageID());
if(msg.getJMSType() != null && msg.getJMSType().equalsIgnoreCase("Text")) {
TextMessage text = (TextMessage)msg;
System.out.println(text.getText());
}
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// System.out.println((++count)+"t"+msg.getText());
}
*Option2*
public void listMsg() {
String destinationName = "queue/XXX";
Context ic = null;
ConnectionFactory cf = null;
Connection connection = null;
try {
ic = getInitialContext();
cf = (ConnectionFactory)ic.lookup("/ConnectionFactory");
Queue queue = (Queue)ic.lookup(destinationName);
connection = cf.createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
QueueBrowser qbrowser = session.createBrowser(queue);
Enumeration<?> qamsgs = qbrowser.getEnumeration();
while (qamsgs.hasMoreElements()){
Message msg = (Message)qamsgs.nextElement();
}
connection.start();
}
catch(Exception e)
{
System.out.println(e);
}
finally
{
if(ic != null)
{
try
{
ic.close();
}
catch(Exception e1)
{
System.out.println(e1);
}
}
}
}
In both the options,messages are getting listed in case of no message consumers at present.If have a live message consumer MDB, then list is returned as null.
I defintely need MDB consumer up and running.But still need to monitor messages.I should be able to do below :
1. List messages]
2. Delete a particular message
3. Change priority
