--------------------------------------------------------------
Hello all,
I'm new to JBoss and to Java (a few months). My background is in .NET / SQL Server, and this stuff is a lot easier there.
So, what I'm trying to do is create a web service that does the following:
1) Allow the (mobile) user to upload an image
2) Store that image in a database
3) Respond to the user with a success message
4) Send notifications out to the user's friends
I've looked all over the place, and there's lots of documentation, but I'm getting a little overwhelmed. I know I need to create a service with a POST method, and have it reply with an HttpResponse. I just can't seem to figure out the best way to do that - I keep running into walls of assumed knowledge that I don't have. I can handle the database part of it, and the notifications can come later. So I'm really hoping someone can point me to a step-by-step that includes instructions on creating a basic service with a POST method and hopefully some instruction on building the response object.
Thanks, and I look forward to learning JBoss!
Mike

[JBoss Web Services] - Deploying Native to AS 6.1.0

"Deploying Native to AS 6.1.0"
To view the discussion, visit: https://community.jboss.org/message/745054#745054
--------------------------------------------------------------
Hi - I downloaded JBoss AS 6.1.0.Final (community) and found it has the CXF stack by default. I read that AS 6.1.0 bundled the Native JBossWS stack 3.4.1.GA and I can see the common/lib/jbossws-native-core.jar. I don't know how to 'enable' and force Native for all web services and/or 'disable' CXF. I thought perhaps this would be an xml config chg but can't find a doc saying that.
So I downloaded the JBossws Native 3.4.1.GA zip, and I modified the ant.properties but I used 610 as the version, and it didn't like me.
Any advice on replacing CXF with NATIVE in JBoss 6.1 would be appreciated. Also please let me know if I am looking for the wrong thing and perhaps I should be specifying NATIVE stack somehow in my WAR?
BUILD FAILED
Target "deploy-jboss610" does not exist in the project "JBossWS-Native".

[jBPM] - Exception retrieving task

"Exception retrieving task"
To view the discussion, visit: https://community.jboss.org/message/744057#744057
--------------------------------------------------------------
Hi All,
I'm getting the exception shown below when trying to get a task using the Mina server in the demo task server included with the installer. I've deployed and started a process definition that has a single human task in it. A row is inserted into the TASK table in the Oracle 11g DB. Other task tables with data are CONTENT (1 row), I18NText (2 rows), PEOPLEASSIGNMENTS_BAS (1 row - 'Administrator') and PEOPLEASSIGNMENTS_POTOWNERS (1 row - 'john'). One item of interest is that the column TASKINITIATOR_ID for the task is null. User 'john' started the process and is the single ActorId in the process defintion. Both the CREATEDBY_ID and ACTUALOWNER_ID columns for the task row are set to 'john'.
Client code:
String name = "ksclient-" + UUID.randomUUID();
TaskClient client = new TaskClient( new MinaTaskClientConnector( name, new MinaTaskClientHandler( SystemEventListenerFactory.getSystemEventListener())));
client.connect( "127.0.0.1", 9123 );
Task jbpmTask = this.getTask( id.longValue() );
utility method used in multiple places:
public Task getTask( long taskId, TaskClient client )
{
BlockingGetTaskResponseHandler responseHandler = new BlockingGetTaskResponseHandler();
client.getTask( taskId, responseHandler );
responseHandler.waitTillDone( 1000 );
return responseHandler.getTask();
}
Any help in resolving this would be appreciated.

Hi,
Well, first of all you are asking jBPM 3 question. As to my knowledge jBPM 3 has been transformed into Activiti and moved out. jBPM 5 is a completely new product and is rooting from the Drools. I can be wrong on this, so forgive me if I am.
Secondly, your question mostly relates to how Hibernate works/performs. Our company currently working with jBPM 5.2 and we had problems with some SQLs containing in orm.xml files coming with jBPM. The SQL’s are less then optimal and Firebird DB is dying executing them. But it is not jBPM but Hibernate (and perhaps Firebird). Our approach was to not using “bad” SQLs but write our own optimized SQLs and execute them via Hibernate’s Native Query mechanisms.
As to jBPM 5 performance - we do not have any complains so far.
Hope this helps.
Thanks,
Vladimir

[jBPM] - Null cmdScopedEntityManager during stateful session load
by Bira Neto

"Null cmdScopedEntityManager during stateful session load"
To view the discussion, visit: https://community.jboss.org/message/744900#744900
--------------------------------------------------------------
I am getting a nullpointerexception during ksession load due to a null cmdScopedEntityManager (from JpaPersistenceContextManager).
First I created a conditional event and executed a instance of this workflow (which results in an active workflow waiting for a condition)
After restarting my server, the session load will fire (or try to fire) an ActivationCreatedEventImpl for my pending rule (named after my process.... RuleFlowStateNode-conditionalTest_2_0-7)
The problem though.... is that when calling getProcessInstancesWaitingForEvent it will try to call a getProcessPersistenceContext() implementation which tries to return a new JpaProcessPersistenceContext( cmdScopedEntityManager );
This cmdScopedEntityManager was not initialized yet though. It seems to be lazy initialized during beginCommandScopedEntityManager (from JpaPersistenceContextManager).
Is that a bug or is there some way or something else I need to add to my environment to use this properly?

Hello, I wrote a Web service client for our vendor's web service. It is working fine with Soap UI and stand-alone Java application. But after i deployed to JBoss, I am having the above error. I am getting this while instatiating the service. After having several of the above messages, I am getting the "Cannot load Java type error. Again the same code work fine as a stand-alone program from Main method.
I am using JBoss 5.1, JDK 1.6, JAX-WS, IntelliJ IDEA as an IDE.
Should i download all xsd's and wsdl to my local drive and refer from there? If I am deploying to JBoss, how do I packages these xsds inside the jar file, and how to refer them? I have the code similar to this
Generated code by JAX-ws:
super(WSDL_LOCATION, new QName(" http:// http://{URL}", "{operation}")); //error is getting here

I even tried modifying the code and converted reader to String and then stored in Map. But in this case, I get an error

Please suggest a solution on this as I have been struggling on this for a while.
