--------------------------------------------------------------
Hi,
i ve worked with the version 5.4 and have resolved this problem but i have an unfinished
project with the version 5.0.0 which must be completed with that version.
To complete a workitem in version 5.4 i had to write :
ksession.getWorkItemManager().completeWorkItem(client.getTask(Task.getId()).getTaskData().getWorkItemId(),
null);
For the version 5.0.0 i 've written a test case like with a java class which is the
following :
public class Jbpm500MainTest {
private static Log log = LogFactory.getLog(Jbpm500MainTest.class);
static StatefulKnowledgeSession ksession =null;
public static ProcessInstance processInstance=null;
public static void main( String[] args) {
///////////////part 1 : creating session ///////////////////////
try {
UserTransaction ut = (UserTransaction) new
InitialContext().lookup( "java:comp/UserTransaction" );
ut.begin();
ksession = JbpmAPIUtil.getSession("modele1.bpmn");
/*Create the knowledge base */
KnowledgeRuntimeLogger logger =
KnowledgeRuntimeLoggerFactory.newThreadedFileLogger(ksession, "testlog", 1000);
CommandBasedWSHumanTaskHandler taskHandler = new
CommandBasedWSHumanTaskHandler(ksession);
ksession.getWorkItemManager().registerWorkItemHandler("Human Task",
taskHandler);
taskHandler.connect();
ut.commit();
logger.close();
} catch (Throwable t) {
//log.error(t.getMessage(), t.getCause());
throw new RuntimeException("error while
creating session",t);
}
UserTransaction ut = null;
try {
ut = (UserTransaction) new
InitialContext().lookup( "java:comp/UserTransaction" );
} catch (NamingException e1) {
e1.printStackTrace();
}
try {
ut.begin();
} catch (NotSupportedException e) {
e.printStackTrace();
} catch (SystemException e) {
e.printStackTrace();
}
System.out.println("Starting process...");
processInstance =
ksession.startProcess("modele1");
ksession.fireAllRules();
try {
ut.commit();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (HeuristicMixedException e) {
e.printStackTrace();
} catch (HeuristicRollbackException e) {
e.printStackTrace();
} catch (RollbackException e) {
e.printStackTrace();
} catch (SystemException e) {
e.printStackTrace();
}
////Looking for tasks 1
java.util.List<TaskSummary> tasks = null;
boolean reservedtaskfound=false;
while(!reservedtaskfound){
tasks =
JbpmAPIUtil.getAssignedTasks("user1");
if(tasks != null && tasks.size()!=0){
System.out.println("-----------------------------------------");
System.out.println("Looking for tasks 1 :

Both 5.0 and 5.4 API's are very different and i coudn't follow the same 5.4
syntaxe for the 5.0.
for example : in the method getTask(long, TaskClientHandler.GetTaskResponseHandler), i
dont know what to put as second parameter, my taskHandler2 does't have a method
GetTaskResponseHandler. and the getTask itself doesn't have the getTaskData()...
Thanks for help !
