Does someone one have a simple explaination w/example showing how to setup the jboss.xml from an ejb-jar.xml? I find nothing on JBOSS or Goggle? Specifically I'm looking for the enterprise beans and resource section. Below is the contents of my ejb-jar.xml.
<enterprise-beans>
<session>
<description>Calculation Appeals Manager EJB</description>
<display-name>CalculationAppealsPortalManagerBean</display-name>

Hi,
I'm using jbpm-flow-5.2.0-SNAPSHOT.jar and got a ClassCastException below with the following Drools flow snippet. I've tried mvel dialet as well and got the same error.
.splitNode(1010).type(Split.TYPE_XOR).name("splitOnShouldActivate")
.constraint(305, "should activate", "code", "Java",
"(Boolean)(context.getVariable(\"shouldActivate\")) == Boolean.TRUE")
.constraint(2000, "should not activate", "code", "Java",
"(Boolean)(context.getVariable(\"shouldActivate\")) == Boolean.FALSE")
.done
Exception in thread "main" java.lang.ClassCastException: org.jbpm.workflow.core.impl.ConstraintImpl incompatible with org.jbpm.process.instance.impl.ConstraintEvaluator

[jBPM] - JBPM4 Migrating from Oracle to Postgres, Transaction Error on JBPM4_LOB

"JBPM4 Migrating from Oracle to Postgres, Transaction Error on JBPM4_LOB"

--------------------------------------------------------------
I have inherited an enterprise service bus style application (MULE,JBPM4,Hibernate,Spring) and have been tasked with migrating the application from Oracle to Postgres. Much of this has gone without a hitch however I have run into a problem that I beleve others have seen before. Specifically Postgres8.4 does not appear to like auto-commits on OID -> LOB, which appears to be key with how JBPM4_LOB works.
[http-80-2] [org.hibernate.util.JDBCExceptionReporter] Large Objects may not be used in auto-commit mode.
Root Exception stack trace:
org.postgresql.util.PSQLException: Large Objects may not be used in auto-commit mode.

at org.hibernate.type.BlobType.get(BlobType.java:80)
Admittedly I'm a bit out of my element, I've tried various forum searched and googles but haven't found a beginners guide to a none beginneres topic. It would appear I must add a transaction around JBPM4_LOB even though in the context that it is used it is absolutely reaad only.
Nowehere else do I use BLOB's and right now I've got the various jbpm4 libraries (maven) on my classpath. But I'm at a loss on how to deal with this issue surrounding auto-commit. I've tried various forms of turning auto-commit off at the hibernate level but to no avail. Previous seraches in the forum suggest others have had this issue but I'm not sure if anyone has recieved an answer. Any help or sympathy is greatly appreciated.
Thanks
Jeff

While waiting for feedback on the above, I decided to try approach number 2
It will use this persistence.xml file (contrary to the above post, I uncommented the node "jta-data-source" ):
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<persistence version="1.0" xsi:schemaLocation=" http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_1_0.xsd http://java.sun.com/xml/ns/persistence/orm_1_0.xsd"
xmlns:orm=" http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm" xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance http://www.w3.org/2001/XMLSchema-instance" xmlns=" http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence">
<persistence-unit name="org.jbpm.persistence.jpa" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>jdbc/processInstanceDS</jta-data-source>
<class>org.drools.persistence.info.SessionInfo</class>
<class>org.jbpm.persistence.processinstance.ProcessInstanceInfo</class>
<class>org.drools.persistence.info.WorkItemInfo</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/>
<property name="hibernate.max_fetch_depth" value="3"/>
<property name="hibernate.hbm2ddl.auto" value="update"/>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.BTMTransactionManagerLookup"/>
</properties>
</persistence-unit>
</persistence>
I try to initiate the database connection like proposed in the jBPM documentation:
PoolingDataSource ds = new PoolingDataSource();
ds.setUniqueName("jdbc/processInstanceDS");
ds.setClassName("net.sourceforge.jtds.jdbc.Driver");
ds.setMaxPoolSize(3);
ds.setAllowLocalTransactions(true);
ds.getDriverProperties().setProperty("user", "myUser");
ds.getDriverProperties().setProperty("password", "myPassword");
ds.getDriverProperties().put("URL", "jdbc:jtds:sqlserver://192.168.117.129:1433;databaseName=myDatabase");
ds.init();
But when I start everything, the above code crashes with:
...
Caused by: bitronix.tm.utils.PropertyException: no writeable property 'URL' in class 'net.sourceforge.jtds.jdbc.Driver'
at bitronix.tm.utils.PropertyUtils.getSetter(PropertyUtils.java:318)
at bitronix.tm.utils.PropertyUtils.setDirectProperty(PropertyUtils.java:217)
at bitronix.tm.utils.PropertyUtils.setProperty(PropertyUtils.java:83)
at bitronix.tm.resource.common.XAPool.createXAFactory(XAPool.java:314)

at bitronix.tm.resource.jdbc.PoolingDataSource.buildXAPool(PoolingDataSource.java:85)
at bitronix.tm.resource.jdbc.PoolingDataSource.init(PoolingDataSource.java:72)
... 58 more
I looked this up on the net for a while and found that I could defin each parts of the URL in separate components like this (Though I have no clue as to how the connection will be initiaterd since the server type is not provided):
...
ds.getDriverProperties().setProperty("serverName", "192.168.117.129");
ds.getDriverProperties().setProperty("portNumber", "1433");
ds.getDriverProperties().setProperty("databaseName", "racm_identity_data");
In anycase, this also crashes with:
Caused by: bitronix.tm.utils.PropertyException: no writeable property 'user' in class 'net.sourceforge.jtds.jdbc.Driver'
at bitronix.tm.utils.PropertyUtils.getSetter(PropertyUtils.java:318)
at bitronix.tm.utils.PropertyUtils.setDirectProperty(PropertyUtils.java:217)
at bitronix.tm.utils.PropertyUtils.setProperty(PropertyUtils.java:83)
at bitronix.tm.resource.common.XAPool.createXAFactory(XAPool.java:314)
at bitronix.tm.resource.common.XAPool.<init>(XAPool.java:63)
at bitronix.tm.resource.jdbc.PoolingDataSource.buildXAPool(PoolingDataSource.java:85)
at bitronix.tm.resource.jdbc.PoolingDataSource.init(PoolingDataSource.java:72)
... 58 more
So with one technique or the other, I always get countered by some obscure problems time after time
