--------------------------------------------------------------
Hi there.
I'm having a problem trying to run a process that has a Work Item. The server can't find the implementation for the Work Item Handler. These are the steps I follow.
First I create the work item in drools-guvnor, it is called 'Activo1', and it's defined as follows:
import org.drools.process.core.datatype.impl.type.ObjectDataType;
import org.drools.process.core.datatype.impl.type.StringDataType;
[
[
"name" : "Activo1",
"parameters" : [
"MyFirstParam" : new StringDataType(),
],
"results" : [
"Result" : new StringDataType()
],
"displayName" : "My Task",
"icon" : "",
]
]
Then, I create a simple process with a start event, the work item, and the end event. I build a snapshot of the package and the process appears in the list of available processes in the jbpm-console.
Next, I edit the conf/META-INF/CustomWorkItemHandlers.conf so it looks like this:
[
"Log": new org.jbpm.process.instance.impl.demo.SystemOutWorkItemHandler(),
"Activo1": new defaultPackage.Activo1()
]
I use ant stop.demo, and then ant start.demo, then I check in the console server war that the CustomWorkItemHandlers file is properly updated. So far it's ok.
For the implementation, I created a folder called 'defaultPackage' and, inside, I create an Activo1.java file with the following contents:
package defaultPackage;
import org.drools.runtime.process.*;
public class Activo1 implements WorkItemHandler{
public void executeWorkItem(WorkItem workItem, WorkItemManager manager) {
System.out.println("GOOD BYE WORLD");
manager.completeWorkItem(workItem.getId(), null);
}
public void abortWorkItem (WorkItem workItem, WorkItemManager manager) {
// Nothing
}
}
In order to compile it, I use
javac -cp "runtime/lib/*" defaultPackage/Activo1.java
And in order to create the JAR file I use this:
jar cfe Activo1.jar defaultPackage.Activo1 defaultPackage
The previous two commands may be the part that's wrong, because I'm an absolute java noob.
I copy the JAR file in all the 'lib' folders I come across, namely $installer/lib, $installer/runtime/lib and $installer/jboss[...]/standalone/lib.
When I launch the process in the jbpm console, I get the following error in the SERVER.LOG file:
Could not commit session: org.jbpm.workflow.instance.WorkflowRuntimeException: [defaultPackage.Proceso1:4 - My Task:2] -- Could not find work item handler for Activo1
HOWEVER, If I change the CustomWorkItemHandlers.conf file so it looks like this:
[
"Log": new org.jbpm.process.instance.impl.demo.SystemOutWorkItemHandler(),
"Activo1": new org.jbpm.process.instance.impl.demo.SystemOutWorkItemHandler()
]
and then I launch the process, the default SystemOut work item handler works OK and I get the following in the LOG file:
[stdout] (http-localhost-127.0.0.1-8080-1) Executing work item WorkItem 5 [name=Activo1, state=0, processInstanceId=5, parameters{TaskName=Activo1}]
So the work item definition and the model definition seem to be OK. The problem seems to be in the place or the way the JAR was generated.
Please help!

--------------------------------------------------------------
I have an issue whenever I try to startup the AS7 runtime from eclipse servers view. I've setup an mssql server datasource and it throws an ssl exception. The server is not configured to require ssl. This does not happen when I start it up from command line by issueing a standalone.bat.
Any ideas???
The exception I get is as the following:

[JBoss Tools] - m2e-wtp 0.17.0 has been released!

"m2e-wtp 0.17.0 has been released!"

--------------------------------------------------------------
h2. With bits of JBoss Tools in it
On behalf of the m2e-wtp team, I'm pleased to announce the immediate availability of m2e-wtp 0.17.0, right on time to accompany the Juno SR2 release.
This 0.17.0 release primarily introduces new optional Java EE configurators, contributed by the JBoss Tools and JBoss Developer Studio team.
https://community.jboss.org/servlet/JiveServlet/showImage/38-5147-20349/M... https://community.jboss.org/servlet/JiveServlet/downloadImage/38-5147-203...
* JAX-RS project configurator : installs the JAX-RS Facet to war projects having JAX-RS dependencies
* JSF project configurator : installs the JSF Facet to war projects having a WEB-INF/faces-config.xml, JSF dependencies or defining a FacesServlet in web.xml
* JPA project configurator : installs the JPA Facet to java projects having a META-INF/persistence.xml descriptor
Read the http://wiki.eclipse.org/M2E-WTP/New_and_Noteworthy/0.16 New and Noteworthy and https://bugs.eclipse.org/bugs/buglist.cgi?query_format=advanced&bug_statu... changelog to learn more about the new features and fixes this version brings to you.
h2. Installation and gotchas
m2e-wtp requires at least m2e 1.1 but *1.3* is **strongly** recommended, in order to take advantage of the eclipse-to-maven project conversion improvements, as well as some fixes in classpath resolution for launch configurations.
Since WTP's Dali project changed its API between Juno and Kepler, so m2e-wtp is now available from 2 different update sites :
* http://download.eclipse.org/m2e-wtp/releases/juno http://download.eclipse.org/m2e-wtp/releases/juno for Indigo and Juno
* http://download.eclipse.org/m2e-wtp/releases/kepler http://download.eclipse.org/m2e-wtp/releases/kepler for Indigo and Juno
You can also install m2e-wtp from the Eclipse Marketplace (http://marketplace.eclipse.org/node/441371).
*Please note that, m2e-wtp and JBoss Tools JPA, JSF JAX-RS Configurators overlap and can not be installed together.*
* In Eclipse versions prior to Juno SR2, if you try to update your Eclipse installation via "*+Help > Install New Software...+*", the optional configurators won't install because of the conflict with JBoss Tools. If you updated your version of Eclipse to Juno SR2, the m2e-wtp configurators should be seen as suitable replacement for their JBoss Tools counterparts.
* For all Eclipse versions, if you add the m2e-wtp update site to your list of Available Update Sites, doing "*+Help > Find Updates+*" everything should update properly.
As always, the safest path to upgrade is to start from a clean Eclipse installation.
h2. Destination Kepler
In the next version, we'll make sure Java EE 7 is given some proper love (i.e. make sure all the new upcoming Facet will be properly configured automatically).
And if everything goes according to plan, starting from Kepler Milestone 6, m2e-wtp.next should be included in the Eclipse Java EE distribution.
Enjoy,
Fred.

[EJB3] - EJB3 is slow sometimes

"EJB3 is slow sometimes"

--------------------------------------------------------------
Hi,
We have EJB(EJB3.0) application which is deployed on JBoss 5.0, we feel sometimes EJB takes long time to return the data(data volume is always same) to invoker.
@Stateless(name = "RequiresNewSessionBean")
@RemoteBinding (jndiBinding = "N_All/RequiresNewSessionBean/remote")
@LocalBinding (jndiBinding = "N_All/RequiresNewSessionBean/local")
@TransactionManagement(TransactionManagementType.CONTAINER)
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
*com.test.ejb.RequiresNewSessionBean*
*com.test.ejb.LocalSessionBeanInvoker* (this class has only invoking parts) will invoke "*com.test.ejb.RequiresNewSessionBean*"
As you see the below 3 scenarios, execution of "*com.test.ejb.RequiresNewSessionBean*" has been finished but it takes time to return to invoker.
The time taken is changing from "*8 ms*" to maximum "*150 ms*" in my local system.
But in our production server this time taken is went up to "*3000 ms"* (only sometimes not all the times, by default it will be within 1 ~ 2 ms in Production server)
Please share your suggestions to overcome this issue.

[JBoss Tools] - How to avoid should be mapped with insert="false" update="false"

Hi
I'm facing a problem when i try to use the hql query editor in eclipse.
[Repeated column in mapping for entity (should be mapped with insert="false" update="false")]
I have my Mysql db filled with tables with relations and data
I need to generate all the reversed-eng classes and xml, so in the hibernate config i select Hibernate Version 3.6 (but seems that there are no differences if i choose other, like in the options, i can choose mysql innodb dialect or mysql... seems the same)
Then i open the "Hibernate Code generation configurations..."
I check in the Main:
Generate basic typed composite ids
Detect optimistic lock colums
Detect many-to-many tables
Detect one-to-one associations
In the Exporters:
Domain code (.java)
Hibernate XML Mappings
Hibernate XML configuration
The generation runs fine, but when i try to operate a simple hql query (from tablename) i got this error:
(generated by hbm2java)
Unhandled event loop exception
org.hibernate.MappingException: Repeated column in mapping for entity: my.test.hibernate.SicComDdtOut column: SCDO-comm (should be mapped with insert="false" update="false")
I understand where the problem is and how i can avoid it is explained(should be mapped with insert="false" update="false")
But, i have many tables with many relations, and i'm still developing the database, so that means that i'll make some changes for sure.
If i follow the suggestion i must edit each problem everytime that i re-generate the code.
So i'm asking for help, is that the right way to solve this problem?
Am i missing something?
Thankyou in advance.
I'm using:
Eclipse: Version: 4.2.1.v20120814-120134...
Hibernate Tools for Eclipse Version: 3.6.0.Final-v20121205-1936-B77
Please, forgive me if i posted in a wrong section. :)

Hi,
I get the following error:
java.lang.ClassCastException: com.sun.jersey.server.impl.provider.RuntimeDelegateImpl cannot be cast to org.jboss.resteasy.spi.ResteasyProviderFactory at org.jboss.resteasy.spi.ResteasyProviderFactory.getInstance(ResteasyProviderFactory.java:330) at de.webshop.test.util.RegisterResteasy.register(RegisterResteasy.java:11) at de.webshop.test.BestellverwaltungTest.setup(BestellverwaltungTest.java:56) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:617) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:27) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:46) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)
After I run this code:
*package* de.webshop.test.util; *import* org.jboss.resteasy.plugins.providers.RegisterBuiltin; *import* org.jboss.resteasy.spi.ResteasyProviderFactory; *public* *abstract* *class* RegisterResteasy { *private* *static* *boolean* registered = *false*; *public* *static* *void* register() { *if* (!registered) { ResteasyProviderFactory resteasyProviderFactory = ResteasyProviderFactory.getInstance(); RegisterBuiltin.register( resteasyProviderFactory ); registered = *true*; } } }
What can be the reason ? Thanks for help in advance. And don't just say 'You're mixing Jersey and Resteasy', I don't know what that means and there's no Jersey dependencies in my pom.
