--------------------------------------------------------------
Hi ,
Actually I want to run the stand-alone service *"HumanTaskService"* via Jboss
but not by ant.
And in this I want my Oracle database is used for all the transactions instead of its own
db.
So I make the necessary changes in the *+jbpm-human-task-5.1.0.Final.jar:+*
I changed the Persistence.xml as I used the JTA data-source for it:
<persistence-unit name="org.jbpm.task" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
* <jta-data-source>java:/testDS1</jta-data-source> *
<class>org.jbpm.task.Attachment</class>
<class>org.jbpm.task.Content</class>
<class>org.jbpm.task.BooleanExpression</class>
<class>org.jbpm.task.Comment</class>
<class>org.jbpm.task.Deadline</class>
And my datasource is:
<datasources>
<xa-datasource>
<jndi-name>testDS1</jndi-name>
<xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
<xa-datasource-property
name="URL">jdbc:oracle:thin:@172.xx.x.251:1521:lupin</xa-datasource-property>
<user-name>xxxxx</user-name>
<password>xxxxx</password>
</xa-datasource>
</datasources>
It is successfully deployed in the jboss.
But when I want to start "humantaskservice" code in the JBoss then it gives the
following error when I am trying to add users:
public void startTaskService() {
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("org.jbpm.task");
TaskService taskService = new TaskService(emf,
SystemEventListenerFactory.getSystemEventListener());
TaskServiceSession taskSession = taskService.createSession();
// Add users
Map vars = new HashMap();
Reader reader = new InputStreamReader( StartTaskService.class.getResourceAsStream(
"LoadUsers.mvel" ) );
Map<String, User> users = ( Map<String, User> ) eval( reader, vars
);
for ( User user : users.values() ) {
taskSession.addUser( user );
}
reader = new InputStreamReader( StartTaskService.class.getResourceAsStream(
"LoadGroups.mvel" ) );
Map<String, Group> groups = ( Map<String, Group> ) eval( reader, vars
);
for ( Group group : groups.values() ) {
taskSession.addGroup(group);
}
// start server
MinaTaskServer server = new MinaTaskServer(taskService);
Thread thread = new Thread(server);
thread.start();
taskSession.dispose();
System.out.println("Task service started correctly !");
System.out.println("Task service running ...");
}
*the error is:*
