Hi,
I'm getting an error when I try to start a process in JBPM-Console. This usually happens after a jboss restart or a system restart (not everytime).
The only way I can fix this is by dropping the databases (jbpm5, task) and recreating them. Note: I'm using mysql as my database. I have attached my standalone.xml and the persistence.xml (~/Desktop/jbpm-installer/jboss-as-7.0.2.Final/standalone/deployments/jbpm-gwt-console-server.war/WEB-INF/classes/META-INF/persistence.xml) with this.
Could you help me to resolve this problem?

[JBoss Messaging] - JBOSS Connection Issue with MQ

Hi,
Let me explain the scenario:
1. I will be sending the message to the JMS queue which is delivered successfully. In the mean time i will stop the server then it throws the exception marked in Red.
2. Next i will restart the server. Exactly after 5 mins it display's the message it got reconnected successfully which is marked in Green.
3. After it gets connected successfully again am able to send the messages successfully to the queue.
Now i like to understand the below points
1. How this is getting reconnected exactly after 5 mins, where is the configuration setting?
2. It is observed that if i disconnect MQ for the whole night without shutting down the JBOSS then next day my JBOSS will not able to reconnect to MQ and will not be able to process the JMS messages. Here I like to understand after shutting down and restart the MQ it used to connect automatically. But when its closed from the whole night, next day JBOSS is not able to identity the MQ. Is there any special configuration setting for this?
The below message is from the console.

[EJB3] - EJB & PostgreSQL FK?

Hi everyone,
im trying to deploy my EJB.jar on my new JBOSS 7.1.1. Well the deploy of the EJB-Container works like a charm. All Tables have been created, correctly. But I am unable to insert any Data in any Table where @ManyToOne Annotations are declared.
Example: Unidirectional ManyToOne
public class A
{
private Integer id;
@Id
@GeneratedValue(stretegy=Generation.TYPE=Auto)
public Integer getId(){ return id;}
public void setId(Integer id){ this.id=id;}
}
public class B
{
private Integer id;
@Id
@GeneratedValue(stretegy=Generation.TYPE=Auto)
public Integer getId(){ return id;}
public void setId(Integer id){ this.id=id;}
private A a;
@ManyToOne
@JoinColumn(name="a_id", nullable=false)
public A getA() {return a;}
public void setA(A a){ this.a=a;}
}
this code, creates in PostgresSQL two Tables with (a, b) with the corresponding Columns (a = id) (b = id, a_id)
Additional there are "two" (not one) ForeignKey Constraints defined, in Table "b":
- fk.... foreign key (a_id) references a (id)
- fk.... foreign key (id) references a(id)
the second FK-Constraint makes trouble:
INSERT A (id=1) = OK!
INSERT B (id=1, a_id=1) = OK!
INSERT B (id=2, a_id=1) = ERROR !!!!!!
DETAIL key (id) = 2 is not present in table "a"
where is my fault?
Thanks for Advice
