I Don't think Drools Flow is used by this user-list group. I am searching at wrong place.
Can any one help me in getting a "link or sample on MySQL or Postgress with Human Task process"............

Hi,
I was trying to change the persistence settings for human task process
server for using MySQL instead of H2DB.
I was following the Drools Flows Documentation on chapter <a href="http://5.1.3." target="_blank">5.1.3.</a>:
Configuring Persistence.(<a href="https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-flow/html_single/index.html" target="_blank">https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-flow/html_single/index.html</a>
#d0e1157)
I read on docs that I should override the persistence.xml of the
drools-process-enterprise.jar, create the drools.session.conf with
some contents (i don`t undestand` what it is...) and put them on my
project META-INF directory... ok?
I created the files as stated on docs but it didn't work... My
example runned ok, but using the H2DB and not my MYSQL.
// Use persistence.xml configuration
emf =
Persistence.createEntityManagerFactory("org.drools.persistence.jpa");
taskService = new TaskService(emf);
taskSession = taskService.createSession();
server = new MinaTaskServer(taskService);
Thread thread = new Thread(server);
thread.start();
Thread.sleep(500);
System.out.println("Server started ...");
After some investigation I could see that the example recommended by
Mark Proctor (TaskLifeCycleTest.java, and others that use
MinaTaskServer) use that
is setting on drools-process-task.jar and not the
"org.drools.persistence.jpa" on drools-process-enterprise.jar as
stated on documentation...
First question, which one should I use for use the Drools Flows Server
and Client?
emf =
Persistence.createEntityManagerFactory( "org.drools.task" );
emf =
Persistence.createEntityManagerFactory("org.drools.persistence.jpa");
I test the first option. I changed the persistence.xml file and use
the code below:
// Use persistence.xml configuration
emf = Persistence.createEntityManagerFactory("org.drools.task");
taskService = new TaskService(emf);
taskSession = taskService.createSession();
server = new MinaTaskServer(taskService);
Thread thread = new Thread(server);
thread.start();
Thread.sleep(500);
System.out.println("Server started ...");
Hummm.... It runs and connect well to my MySQL. but now it brings me a
error...
java.lang.IllegalArgumentException: Named query not found:
UnescalatedDeadlines
at
org
.hibernate
.ejb
.AbstractEntityManagerImpl
.createNamedQuery(AbstractEntityManagerImpl.java:108)
at org.drools.task.service.TaskService.(TaskService.java:84)
at org.drools.task.service.TaskService.(TaskService.java:68)
It sounds like it was not possible to find orm.xml that is on META-INF
of drools-process-task.jar.
But when I copy the orm.xml file to my project META-INF it works ok....
Could someone give some ideas how can I solve this problem..
Thanks a lot
Cristiano
