[JBoss-user] [JBoss jBPM] - Using hibernate annotation with jBPM
Hi,
I just spend a few houres to figure how to use Hibernate Annotaiton with jBPM.
Here is the receipt (can probably be improved):
1-- Create an implementation of the db persistence service:
-
package com.btc.fwk.jbpm;
[Cut imports]
public class PersistenceService extends DbPersistenceServiceFactory {
private static final Log _log =
LogFactory.getLog(PersistenceService.class);
private Configuration _configuration;
public PersistenceService() {
super();
_log.info(Creating Persistence Service);
}
public synchronized Configuration getConfiguration() {
_log.info(Creating AnnotationConfiguration);
if (_configuration == null) {
String hibernateCfgXmlResource = null;
if (JbpmConfiguration.Configs
.hasObject(resource.hibernate.cfg.xml)) {
hibernateCfgXmlResource =
JbpmConfiguration.Configs
.getString(resource.hibernate.cfg.xml);
}
String hibernatePropertiesResource = null;
if
(JbpmConfiguration.Configs.hasObject(resource.hibernate.properties)) {
hibernatePropertiesResource =
JbpmConfiguration.Configs.getString(resource.hibernate.properties);
}
_configuration = new AnnotationConfiguration();
_log.info(XML configuration file = +
hibernateCfgXmlResource);
_log.info(Resource file = +
hibernatePropertiesResource);
_configuration.configure(hibernateCfgXmlResource);
if( hibernatePropertiesResource != null ) {
_log.debug(Setting Persistence hibernate
properties from + hibernatePropertiesResource);
Properties properties = new Properties();
InputStream is = null;
try {
is =
PersistenceService.class.getClassLoader().getResourceAsStream(hibernatePropertiesResource);
properties.load(is);
} catch(Exception e) {
_log.error(e);
_log.debug(Hibernate properties +
hibernatePropertiesResource + not found);
} finally {
if( is != null )
try {
is.close();
} catch (IOException e) {
_log.error(e);
}
}
_configuration.setProperties(properties);
}
}
return _configuration;
}
}
2-- Declare the service
---
In jbpm.cfg.xml:
jbpm-context
!--
--
3-- Declare the annotated classes
-
Declare the annotated classes into the hibernate.cfg.xml file.
Hope this help

[JBoss-user] [JBoss jBPM] - Mandatory default transition
After looking on the signal() source code, it looks that the default transition is mandatory for a node in order to be able to call signal(String). I'd like to use only named transitions and events. Is there is any reason?

You can use WebServices to access remotely to your servers. Just call your web services from your jbp ActionHandler. my 2 cts View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3929308#3929308 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3929308 --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.

[JBoss-user] [JBoss jBPM] - Re: Some question of a Beginner in JBPM
jBPM is just a Java API. You can use it in a J2SE Java application, in a J2EE Web application or inside of an EJB Container. I'm not sure to understand your question, but if you just want to try some application code in Eclipse, you don't need a server. You the JBoss IDE and create jBPM project. taskInstance.setActorId directly assign the task to an actor. AssignmentHandler may call setActorId, but the class first need to find an actorId. An example of AssignementHandler can be a Task Dispatcher which assign dynamically the tasks according to the workload of an actor set. I don't get you for your last question.

[JBoss-user] [JBoss jBPM] - jBPM + EntityManager
Hi, Is it possible to develop the applicaiton code with EJB3 entities annotations and using jBPM ? EntityManager and jBPM must share the same Hibernate Session and cache. Should I hack the EntityManagerImpl to use the SessionFactory build by jBPM ?

[JBoss-user] [JBoss jBPM] - TaskNode ClassCastException
I run a trivial example. The token is located on a TaskNode. I checked. 1 Token token = processInstance.getRootToken(); 2 Node node = token.getNode(); 3 TaskNode taskNode = (TaskNode)node; The node is not a TaskNode, but an hibernate proxy, and I get the following exception on line 3: java.lang.ClassCastException: org.jbpm.graph.def.Node$$EnhancerByCGLIB$$cdd399be J2SE 5 application jBpm 3.1 Any idea ?

Strange, If of write: 1 Token token = processInstance.getRootToken(); 2 Node node = processDefinition.getNode(token.getNode().getName()); 3 TaskNode taskNode = (TaskNode)node; It works ! It looks that the Node returned by the token is not correctly instanciated. Something I didn't get or a bug ?

Fixed by writing: 1 Token token = processInstance.getRootToken(); 2 TaskNode taskNode = (TaskNode)jbpmContext. getSession(). load(TaskNode.class, token.getNode().getId()); See: http://www.jboss.com/index.html?module=bbop=viewtopict=73123 View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=3929055#3929055 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=3929055 --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
