[JBoss jBPM] - Re: Transaction Issue
by Toriton
Got it.
not more problem and with an XA DataSource. the problems was, this :
UserTransaction
Not specified in other Config files.
If could Help this is my final configuration:
XA DS Oracle (cut and past of the example under JBOSS):
| <?xml version="1.0" encoding="UTF-8"?>
| <datasources>
|
| <xa-datasource>
| <jndi-name>JbpmDS</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:thin:@localhost:1521:XE</xa-datasource-property>
| <xa-datasource-property name="User">system</xa-datasource-property>
| <xa-datasource-property name="Password">123</xa-datasource-property>
| <!--user-name>system</user-name>
| <password>123</password-->
| <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>
| <application-managed-security/>
| <!-- reduce isolation from the default level (repeatable read) -->
| <!--transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation-->
| <!-- separate connections used with and without JTA transaction -->
| <no-tx-separate-pools />
| <!-- disable transaction interleaving -->
| <!-- track-connection-by-tx /-->
| <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection-checker-class-name>
|
| <!--mbean code="org.jboss.resource.adapter.jdbc.vendor.OracleXAExceptionFormatter"
| name="jboss.jca:service=OracleXAExceptionFormatter">
| <depends optional-attribute-name="TransactionManagerService">jboss:service=TransactionManager</depends>
| </mbean-->
|
| <!-- corresponding type-mapping in conf/standardjbosscmp-jdbc.xml -->
| <metadata>
| <type-mapping>Oracle9i</type-mapping>
| </metadata>
| </xa-datasource>
|
| </datasources>
|
and the Hibernate.cfg (missing just the part of all hbm.xml files):
| <property name="hibernate.connection.datasource">java:/JbpmDS</property>
| <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
| <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property>
| <property name="jta.UserTransaction">UserTransaction</property>
|
| <!-- ################################### -->
| <!-- # common settings # -->
| <!-- ################################### -->
|
| <!-- Automatic schema creation (begin) ===
| <property name="hibernate.hbm2ddl.auto">create</property>
| ==== Automatic schema creation (end) -->
|
| <!-- Simple memory-only cache -->
| <property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
|
| <!-- logging properties -->
| <property name="hibernate.format_sql">true</property>
| <property name="hibernate.use_sql_comments">true</property>
|
I hope that this can help anyone that need a start configuration.
Thanks for the reply .

jbpm prototype findings tasks, timers and cleaning up
by Dan Oxlade
We're currently prototyping a jBpm solution and have so far found it to
be very effective.
We are now experimenting with tasks and timers and have had to implement
a few features ourselves, I'm not sure if we are using the engine
correctly in doing this and wanted to list my experiences.
Tasks
We found that when leaving a task-node with multiple tasks
signal="first" we leave open tasks. We implemented an action to remove
all open tasks for this node on "node-leave". This seems to be a common
pattern for us.
Timers
Timer only support events at points relative to 'now' i.e "In 3 business
hours"
We have represented a timer in the process that can be dynamic; an
example is a task expiry (which links with the removal of tasks above)
driven by an external business concept.
We implemented our own CreateTimerAction wrapping the jBpm one and use a
strategy for the resolution of 'dueDate'.
This means we use an event node with a nested action (our
CreateTimerAction) to create the Timer at the appropriate place.
Has anyone else has a similar experience and do these concepts make
sense?
Kind regards,
Dan Oxlade

Another configuration:
| <property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property>
| <property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property>
| <property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
| <property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:XE</property>
| <property name="hibernate.connection.username">system</property>
| <property name="hibernate.connection.password">123</property>
| <property name="hibernate.query.substitutions">true 1, false 0</property>
| <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
| <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property>
|
same error.
The Transaction Manager.. is specified for JBoss i think that i can't change it for another right?..
Thanks in advance for any reply.

[JBoss jBPM] - Re: Transaction Issue

Hi brads thanks for reply.
I changed that properties too and many others to try something.
this is the FULL Hiberante configuration ATM (plus all mapping resource hbm.xml that Jbpm need):
| <property name="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</property>
| <property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property>
| <property name="hibernate.connection.datasource">java:/JbpmDS</property>
| <property name="hibernate.transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
| <property name="hibernate.transaction.manager_lookup_class">org.hibernate.transaction.JBossTransactionManagerLookup</property>
|
As you can see i'm using now just the DataSource specified as tx-local (see the post above), and getting the same error with only the DataSource not jdbc properties spefied in the Hibernate.cfg.
I can still loggging in the console, but as usual can't get task or users or insert a new user or group via conosole.
