[JBoss jBPM] - Cannot get all process definition keys - named query missing
by ruszmogi
=== Environment ==============================
- jBPM Version : JBPM4
- Database : Oracle Enterprise
- JDK : java version "1.6.0_10"
- Container : java version "1.6.0_10"
- Configuration : basic configuartion
- Libraries :
=== Process ==================================
=== Environment ==============================
- jBPM Version : which version of jBPM are you using?
- Database : which database and which version of that database
- JDK : which Java version are you using? use 'java -version' to find out
- Container : which Java version are you using? use 'java -version' to find out
- Configuration : is your jbpm.cfg.xml only importing files from the jbpm.jar
lib itself? or did you create a custom config file?
- Libraries : are you using the exact versions of the libs from inside the jbpm
distribution of the version that you're using? or did you change some of the libs?
=== Process ==================================
<?xml version="1.0" encoding="UTF-8"?>

past debug logs here
=== Problem description =========================
I want to get the all deployed processes using the jbpm engine. It looks like there is no named query findProcessDefinitionKeys, which want the hibernate use in DbSessionImpl class .
Is there an other way to get all processes?

[JBoss jBPM] - Re: jBPM 3.2.6.SP1 on Weblogic 11gR1

Hi, i have somes questions.
1- If i try to use the jBPM jobscheduler, what happen to timers and asynchronism ? It will not use EJB timer and JMS (with queues JbpmJobQueue and JbpmCommandQueue ) for this but your own JobExecutor that's right ? And i can delete jbpm-enterprise.jar so ;-)?
2- Why have you created these EJBs if your own implementation is good ?
Actually, under my jboss as, in deploy/jBPM/jbpm-service.sar, my jbpm.cfg.xml file is :
<jbpm-configuration>
|
| <jbpm-context>
| <service name="persistence" factory="org.jbpm.persistence.jta.JtaDbPersistenceServiceFactory" />
| <service name="message" factory="org.jbpm.msg.jms.JmsMessageServiceFactory" />
| <service name="scheduler" factory="org.jbpm.scheduler.ejbtimer.EntitySchedulerServiceFactory" />
| <service name="tx" factory="org.jbpm.tx.TxServiceFactory" />
| <service name="authentication" factory="org.jbpm.security.authentication.DefaultAuthenticationServiceFactory" />
| </jbpm-context>
|
| <string name="jbpm.classLoader" value="context" />
|
| <null name="jbpm.job.executor" />
|
| </jbpm-configuration>
So, persistence, tx and authentification are still OK but i have to change:
<service name="message" factory="org.jbpm.msg.db.DbMessageServiceFactory" />
<service name="scheduler" factory="org.jbpm.scheduler.db.DbSchedulerServiceFactory" />
and put, like in the default configuration file:
<bean name="jbpm.job.executor" class="org.jbpm.job.executor.JobExecutor">
| <field name="jbpmConfiguration"><ref bean="jbpmConfiguration" /></field>
| <field name="name"><string value="JbpmJobExecutor" /></field>
| <field name="nbrOfThreads"><int value="1" /></field>
| <field name="idleInterval"><int value="5000" /></field>
| <field name="maxIdleInterval"><int value="3600000" /></field> <!-- 1 hour -->
| <field name="historyMaxSize"><int value="20" /></field>
| <field name="maxLockTime"><int value="600000" /></field> <!-- 10 minutes -->
| <field name="lockMonitorInterval"><int value="60000" /></field> <!-- 1 minute -->
| <field name="lockBufferTime"><int value="5000" /></field> <!-- 5 seconds -->
| </bean>
Is it right ?
Thx for all.
