[jboss-user] [JBoss jBPM] - Re: JobExecutorThread
the usertransaction is eventually bound to the jndi tree. The problems seems to be is that the 'WorkflowService' is commencing *before* the hibernate service has bound the usertransaction to the jndi tree. i confirmed this by placing trace inside the workflow service code and the userTransaction is only bound some time after the workflow service has commenced. werid i know. i have no understanding how the hibernate service starts and it role in the user transaction/jndi binding. i dont know what differences between jbpm3.2.2-jbpm3.26 would cause such behaviour. -lp View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=4248298#4248298 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=4248298 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

hi all, has anyone implemented their own Task Form GUI, similar to that of the console app? Looking over the jsf4jbpm taglib, it tightly coupled to the undocumented gravel taglib. Q1.

[jboss-user] [JBoss Portal] - Re: upgrade jbpm to 3.2.6: how to
looks the problems seems to be that the JbpmThreadService get started without
having a JbpmContext.
| JbpmThreadService .java
| public void start()
|{
| JbpmConfiguration jbpmConfiguration =
workflowService.getJbpmConfiguration();
| jbpmConfiguration.getJobExecutor().start();
|}
|
|
I am not entirely sure why, but once i programmatically call createJbpmContext
the JbpmThreadService seems to function without error from then.
| context = workflowService.getJbpmConfiguration().createJbpmContext();
|
Q1. is expected behaviour with JbpmContext?
Q2. should client/portlet code be using the workflowservice?

i think i may have found the issue with why my sub process has now variable instances. it seems that the variables need to be 'explicit' copied into the new process definition.

When the sub process instances is finished, all the variables with write access will be copied from the sub process to the super process. The mapped-name attribute of the variable element allows you to specify the variable name that should be used in the sub process. | However i dont want to 'explicitly' copy all my variables over to the new process.

[jboss-user] [JBoss jBPM] - Variable missing in assignment handler
hi all,
my swimlane assignment handler is unable to retrieve variables that have been
previous set in both root token and local token.
the test involves a forkhandler, sub process and swimlane assignment handler.
When inside the SwimlaneAssignmentHandler getVariable() returns null which is
not what i was expecting
| public void assign(Assignable assignable, ExecutionContext
executionContext) {
|
| assertNotNull(shouldnt be null, executionContext.getVariable(IDENTIFIER));
| String expression = (String)executionContext.getVariable(EXPRESSION);
| assertNotNull( shouldnt be null, expression );
|
as it was set in the previous ActivityForkActionHandler.execute()
| public void execute(final ExecutionContext executionContext) throws
Exception {
| .stuff
| Token(rootToken, ITP + item.getId()); //TODO -lp
| newToken.setTerminationImplicit(true);
|
executionContext.getJbpmContext().getSession().save(newToken);
| final ExecutionContext newExecutionContext = new ExecutionContext(newToken);
| newExecutionContext.getContextInstance().createVariable(
| EXPRESSION,
|
item.getResponsibleExpression(),
| newToken);
|
|
I am not sure if the problem is with my process definition of the swimlan
assignment
| swimlane name='responsible'
| assignment
class='com.asteriski.itpflow.action.ActivityForkActionHandlerTest$SwimlaneAssignmentHandler'/
| /swimlane
|
or with how i am setting the local variables against token in the forkHandler
above
i have a attached the entire test case below. It is a bit tedious but i needed
to include all the handler code.
any help is most appreciated.

[jboss-user] [JBoss jBPM] - Re: Variable missing in assignment handler
Further testing reveals that there are NO variables at all available in the
Assignment handler.
I am using Jbpm3.2.6
|
| public void assign(Assignable assignable, ExecutionContext
executionContext) {
|
| MapToken, TokenVariableMap tokenVariableMaps =
executionContext.getContextInstance().getTokenVariableMaps();
| assertNotNull(tokenmap shouldnt be null, tokenVariableMaps);
|
|
Q. Since the ExecutionContext has only one method to retrieve variable
ExecutionContext.getVariable() which seem to be based on the root token. How
can a local variable bound to a token be retrieved from the ExecutionContext?
any help most appreciated.
many thanks

[jboss-user] [EJB 3.0] - onetomany relationship question
i read the 'EJB3 relationships' wiki article
http://www.jboss.org/community/wiki/EJB3relationships and have a question.
| @Entity()
| public class ParentBean implements Serializable
| {
| private SetChildBean listChilds = new HashSetChildBean();
|
| @OneToMany(mappedBy=parent)
| public SetChildBean getChilds()
| {
| return this.listChilds;
| }
| }
|
| @Entity()
| public class ChildBean implements Serializable
| {
| @ManyToOne ()
| public ParentBean getParent()
| {
| return this.parent;
| }
| }
|
|
Q1. essentially why doesnt the following work
| ParentBean parent = ...;
| ChildBean child1 = ...;
| child1.setParent(parent);
|
| ChildBean child2 = ...;
| child2.setParent(parent);
|
| .
|
|ParentBean parentBean = this.entityManager.find(ParentBean.class,
int_ParentId);
|
|
| assertEquals( 2, parentBean.getChilds().size() ); --- why do i get 0
|
|
Q2. Does the parent.setChilds( list) must be called before calling
parent.getChilds() or can is ok set the relationship with a)child1.setParent(p),
child2.setParent(p) or b) having the data loaded from scripts?
currently my parent.getChilds() returns null although there is
parent/child relationship on the many-to-one table.
Q3. I was expceting that the parent.getChilds() executes a query like ('from
child c where c.parent=:parent' )
is my understanding of one-to-many relationship wrong?

[jboss-user] [EJB 3.0] - Re: onetomany relationship question
thanks for the rapid response wolfgang. i added the SQL tracing but there is *no* SQL when calling parent.getChilds(). So if i have understood the 'onetoMany' relationship, it doesnt populated the 'many' unless it has been explicitly set using the parent.setChilds(). This seems an almost pointless relationship. In order to get the list of childs from existing data (ie.reference data), one must use a join query like | em.query( 'from Child child where child.parent_id=:id') | I was hoping the above would be executed during the retrieval of the 'many'. Q1. what exactly is the point of the 'onetoMany' if it is only useful if used when explicitly setting the collection on the 'one' side? any help to clarify the above is most appreciated. -lp View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=4242160#4242160 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=4242160 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [EJB 3.0] - Re: onetomany relationship question
ok it seems that my test cases were erroneous.
i finally got the onetomany to fetch the 'many' by refreshing the entity. This
then invoked the following query
| hibernate: select childbean0_.ID as ID3_, childbean0_.parent_ID as
parent2_3_ from ChildBean childbean0_ where childbean0_.parent_ID=?
|
my test code also shows that the relationship only needs to be set on the many
side.
|
| @Test
| public void one2manyTestWithSettingManySide() {
|
| ParentBean parent = new ParentBean();
| entityManager.persist(parent);
| long id = parent.getId();
|
| ChildBean child1 = new ChildBean();
| child1.setParent(parent);
| entityManager.persist(child1);
|
| ChildBean child2 = new ChildBean();
| child2.setParent(parent);
| entityManager.persist(child2);
|
| Query query = entityManager.createQuery(from ChildBean child
where parent.id=:id);
| query.setParameter(id, id);
| List resultList = query.getResultList();
| assertEquals( 2, resultList.size() );
|
| //check refresh
| entityManager.refresh(parent);
| assertEquals( 2, parent.getChilds().size() );
|
| ParentBean parentBean = entityManager.find(ParentBean.class,
parent.getId());
|
| assertEquals( 2, parentBean.getChilds().size() );
|
| }
|

thanks for your help wolfgang.

hi all, i have a sub process/inner process definition that are currently being deployed by the console app and using the 'binding=late' attribute. Everything is working ok. However trying to deploy using the console app, (inner process first, then sub process definition) without the 'binding=late' attribute, the inner definition is not found.

hi all, i am intrigued how the jbpm-service.sar works? I had it deployed as part of the 3.2.6SP1 deployment. But looking at the jboss-services.xml there is no service or mbean exposed, so not sure how or what it does. However when i deployed my own ear with its own web console BUT without any jbpm jars, the JBPMContext was somehow picked up and everything worked. I am very confused how the JbpmContext is being found other than through the original 3.2.6SP1 deployment jbpm-service.sar. Moving forward should i have the jbpm jars included in my ear or should they be exposed a jboss services?

[jboss-user] [EJB 3.0] - merge one-to-one strategy
hi all,
I am having troubles understanding the EJB3 updating strategy. I am familar
with the traditional mechanism of dealing with just FK when updating a
one-to-one relationship. However with EJB3 the FK is now a object.
From the EJB3trail there is a example that does the following for a persist.
It loads both foreign key objects before setting, then persisting.
| public double calculate (int fundId, int investorId, double saving) {
| 26
| 27 Investor investor =
| 28 em.find(Investor.class,
| 29 Integer.valueOf(investorId));
| 30 Fund fund =
| 31 em.find(Fund.class,
| 32 Integer.valueOf(fundId));
| 33
| 34 int start = investor.getStartAge();
| 35 int end = investor.getEndAge();
| 36 double growthrate = fund.getGrowthrate();
| 37
| 38 double tmp = Math.pow(1. + growthrate / 12., 12. * (end - start) +
1);
| 39 double result = saving * 12. * (tmp - 1) / growthrate;
| 40 Timestamp ts = new Timestamp (System.currentTimeMillis());
| 41
| 42 TimedRecord rec =
| 43 new TimedRecord (fund, investor, saving, result, ts);
| 44 em.persist (rec);
| 45
| 46 return result;
| 47 }
|
Is the same mechanism required when updating?
Unfortunetly the EJB3trail does not have a one-to-one merge example.
Is something like the following performant or are there better mechanisms?
The major issue is executing the load of the FK relationship object. Which
seems expensive when i already have the FK id.
|
| strategy 1
|
| public double update (int recId, int fundId, int investorId, double saving)
{
|
| Investor investor =
| em.find(Investor.class,
| Integer.valueOf(investorId));
| Fund fund =
| em.find(Fund.class,
| Integer.valueOf(fundId));
| TimeRecord rec =
| em.find(Fund.class,
| Integer.valueOf(fundId));
|
| rec.setSaving( saving);
| rec.setFund( fund );
| rec.setInvestor( investor );
| em.merge (rec);
|
| return result;
|}
|
I have tried the following with little success as it complains about transient
Objects
|
| strategy 2 not working.
|
| public double update2 (int recId, int fundId, int investorId, double
saving) {
|
| Investor investor =new Investor( investorId);
| Fund fund = new Fund( fundId);
| TimeRecord rec =
| em.find(Fund.class,
| Integer.valueOf(fundId));
|
| rec.setSaving( saving);
| rec.setFund( fund );
| rec.setInvestor( investor );
| em.merge (rec);
|
| return result;
|}
|
|
So my question is does the merge on one-to-one relationship require fullly
populated detached objects or can it be done with just the id for the FK?

[jboss-user] [EJB 3.0] - @Stateless JNDI bindings
hi all,
since migrating to 4.0.4 GA my stateless session beans are nolonger bound to
the same JNDI name as before.
Previously i could do the following. I assume the default JNDI name was the
interface class name.
| //jb = (Job) ctx.lookup(Job.class.getName());
|
However this is no longer finding the sessionbean.
| @Stateless
| public class JobBean implements Job {
|
what exaclty has changed and what is required to bing the JNDI name?
many thanks

[jboss-user] [EJB 3.0] - NOTYETINSTALLED + JBoss-4.0.4.GA + dependency
hi all,
just migrated to Jboss 4.0.4GA. And my app is failing to deploy with the
following error.
| ObjectName:
jboss.j2ee:ear=asset.ear,jar=business.ejb3,name=ReportBean,service=E
| JB3
| State: NOTYETINSTALLED
| I Depend On:
| persistence.units:unitName=as
|
| --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
| ObjectName: persistence.units:unitName=as
| State: NOTYETINSTALLED
| Depends On Me:
| jboss.j2ee:ear=asset.ear,jar=business.ejb3,name=AssetBean,service=EJB3
|
jboss.j2ee:ear=asset.ear,jar=business.ejb3,name=DepreciationBean,service=EJB
| 3
| jboss.j2ee:ear=asset.ear,jar=business.ejb3,name=JobBean,service=EJB3
| jboss.j2ee:ear=asset.ear,jar=business.ejb3,name=ReportBean,service=EJB3
|
OK so i gather from the forum that JBoss4.0.4 is stricter on the dependancy
checking. I have seen a work around for EJB injection using the
@ignoreDependency but nothing for EntityManagers.
My code is
|
| @Stateless
| public class JobBean implements Job {
|
| @PersistenceContext (unitName=as)
| protected EntityManager em;
|
I have seen many request on the same topics but no solutions. If there is a
solution please point it out so it wont be asked again.
thanks
