[Installation, Configuration & DEPLOYMENT] - Remote debugging with Jboss
by puntino
Hallo,
I'd like to know how to set up my Eclipse 3.4.2 and Jboss in order to debug my application in remote mode.
First of all, I already enabled the line:
set JAVA_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=y %JAVA_OPTS%
In Eclipse, in the debug configuration panel I set the ip address of the jboss server where my web application is hosted, and 8787 as port number.
Then, I lauch my debbuger by clicking on the green beatle and the Jboss got stuck in an infinite loop.
How can I sort it out ?
Aside from this strange behaviour, I can't figure out how it is possible to debug an application running on the server with a debugger that it is installed on the client side where the code is developed...
I would appreciate any help.
Thank you in advance

[JBoss jBPM] - JBPM4: FOREIGN KEY problem
by hexiaofeng
hi.
A question block me, Please help me .thank you very much.
I download jbpm-4.0.CR1. Import jbpm.mysql.create.sql contents to MySql 5.
I create Order and TestUpdate , When I run TestUpdate , some exception print in cnosole. It seems question is FOREIGN KEY problem.
Please tell me how to fix it. Thank you very much.
Below are source code, and exceptin message.

[EJB 3.0] - Re: onetomany relationship question
by lpiccoli
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.
