Issues with deploying JBPM project after ant install.jbpm.into.jboss

[ku6]

Hi,

After I installed JBPM into JBOSS (ant install.jbpm.into.jboss), I deployed a JBPM project into JBOSS.

As soon as the jsp page starts loading, JBPM will lock on JBPM4_property table during the insert. JSP page will hang.

It looks like there is a conflict between JBPM services that is installed in JBoss and another JBPM (from the web app project).

JBPM service hibernate-configure

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE hibernate-configuration PUBLIC

"-//Hibernate/Hibernate Configuration DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

<session-factory>

<property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property>

<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>

<property name="hibernate.connection.url">url</property>

<property name="hibernate.connection.username">user</property>

<property name="hibernate.connection.password">password</property>

<property name="hibernate.format_sql">true</property>

<property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>

<property name="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>

<property name="jta.UserTransaction">UserTransaction</property>

<mapping resource="jbpm.repository.hbm.xml" />

<mapping resource="jbpm.execution.hbm.xml" />

<mapping resource="jbpm.history.hbm.xml" />

<mapping resource="jbpm.task.hbm.xml" />

<mapping resource="jbpm.identity.hbm.xml" />

</session-factory>

</hibernate-configuration>

JBPM web app from my testing project

hibernate-configure

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE hibernate-configuration PUBLIC

"-//Hibernate/Hibernate Configuration DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

<session-factory>

<property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property>

<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>

<property name="hibernate.connection.url">url</property>

<property name="hibernate.connection.username">user</property>

<property name="hibernate.connection.password">password</property>

<property name="hibernate.show_sql">true</property>

<mapping resource="jbpm.repository.hbm.xml" />

<mapping resource="jbpm.execution.hbm.xml" />

<mapping resource="jbpm.history.hbm.xml" />

<mapping resource="jbpm.task.hbm.xml" />

<mapping resource="jbpm.identity.hbm.xml" />

</session-factory>

</hibernate-configuration>

I had on the configure file on my testing project. But it will drop and re-create the JBPM4 tables. So I dropped this line.

<

property name="hibernate.hbm2ddl.auto">create-drop</property

>

My questions is what does ant install.jbpm.into.jboss do? Does it install JBPM as a service in JBOSS?

And once it is installed, can I still deploy another JBPM project into JBOSS? Will co-exist of both cause any conflict?

Thanks,

Does any one has similar issues? It looks like very common  that people deploy JBPM projects after install JBPM.

If I don't install jbpm into Jboss and only deploy my JBPM project then its fine. Now conflicts. But I still don't understand why is that.

Perhaps you should avoid creating new process engine in your application and instead look up for already built one in JNDI.
