how to use Global (managed) transactions in jbpm
Hi,
I'm trying to implement the following process in jbpm:
BEGIN GLOBAL TX 1. An MDB creates a process instance 2. This MDB signal() the instance 3. The NODE that jbpm transitions to has an ActionHandler that generates a JMS message END GLOBAL TX
What I am finding is the JMS message is being sent by the action class immediaetly, not when the MDB that creates the process instance commits. What I'd like to happen is all of the updates (the process definition to Oracle and the new JMS message to JBoss MQ) happens simultaneously.
My configuration is as follows:
- JBoss 4.0.2
- JBPM 3.0.1
- I've confgired Hibernate 3 to use Oracle for persistance with my jbpm.hibernate.properties as follows:
hibernate.dialect=org.hibernate.dialect.Oracle9Dialect # for Oracle 8 compatibility use #hibernate.dialect=org.hibernate.dialect.OracleDialect hibernate.show_sql=false #hibernate.c3p0.min_size=1 #hibernate.c3p0.max_size=3 hibernate.query.substitutions=true 1, false 0 hibernate.connection.datasource=java:/MY_DS
and Jbpm is persisting everything to oracle
- The MY_DS Datasource is set up as an XA datasource as follows:
my_ds-ds.xml
<xa-datasource> <jndi-name>MY_DS</jndi-name> <track-connection-by-tx/> <isSameRM-override-value>false</isSameRM-override-value> <xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class> <xa-datasource-property name="URL">JDBC:oracle:oci:@XXX</xa-datasource-property> <xa-datasource-property name="User">user</xa-datasource-property> <xa-datasource-property name="Password">passwd</xa-datasource-property> <!-- Uses the pingDatabase method to check a connection is still valid before handing it out from the pool --> <!--valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection-checker-class-name--> <!-- Checks the Oracle error codes and messages for fatal errors --> <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name> <!-- Oracles XA datasource cannot reuse a connection outside a transaction once enlisted in a global transaction and vice-versa --> <no-tx-separate-pools/> <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) --> <metadata> <type-mapping>Oracle9i</type-mapping> </metadata> </xa-datasource>
I tried basing the advice code on this post:
http://www.jboss.org/index.html?module=bb&op=viewtopic&t=67431
So I've updated the jbpm.hibernate.properties file to look like this:
hibernate.dialect=org.hibernate.dialect.Oracle9Dialect # for Oracle 8 compatibility use #hibernate.dialect=org.hibernate.dialect.OracleDialect hibernate.show_sql=false hibernate.query.substitutions=true 1, false 0 hibernate.connection.datasource=java:/MY_DS # hibernate.show_sql=true # added to support XA TX hibernate.jndi.class=org.jboss.naming.NamingContextFactory #hibernate.transaction.factory_class=net.sf.hibernate.transaction.JTATransactionFactory hibernate.transaction.factory_class=org.hibernate.transaction.JTATransactionFactory hibernate.transaction.flush_before_completion=true hibernate.connection.release_mode=after_statement hibernate.transaction.auto_close_session=true
However, when booting jbpm now reports the following exception. I get this exception whether I use net.sf.hibernate.transaction.JTATransactionFactory or org.hibernate.transaction.JTATransactionFactory
I assumed that the original poster was using Hib 2.0, so I updated the package names accordingly.
