I have created the Stardust schema in an Oracle database. When I start the Tomcat server in Eclipse the exception listed below is thrown.

Exception:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ag.carnot.db.jca.XaDataSourceMCF#15b0ff7' defined in ServletContext resource [/WEB-INF/config/ipp/spring/carnot-spring-context.xml]: Cannot resolve reference to bean 'carnotXaAuditTrailDataSource' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'carnotXaAuditTrailDataSource' defined in ServletContext resource [/WEB-INF/config/ipp/spring/carnot-spring-context.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [oracle.jdbc.xa.OracleXADataSource]: Is it an abstract class?; nested exception is java.lang.InstantiationException

carnot.properties:
 AuditTrail.DataSource = java:comp/env/jdbc/AuditTrail.DataSource

 AuditTrail.URL = jdbc:oracle:thin:@<hostname>:1521:<dbname>
 AuditTrail.Schema = <schemaname>
 AuditTrail.User = <username>
 AuditTrail.Password = <password>

It seems you have two datasources in your carnot-spring-context.xml for the AuditTrail DB. One with local parameters and one via JNDI lookup. In this case you should only use the JNDI one and comment out the other. Just search through the file for references of carnotXaAuditTrailDataSource (the one you're removing) and change them to point to the one with the JNDI lookup.

I made the suggested change and the server started fine. I deployed a model and when I click on the "My Startable Processes" link I get the following error:

Check out your carnot.properties. You probably have AuditTrail.UseLockTables enabled. That's not required using Oracle database. Just set above property to false.

Problem resolved after making this change.

The above solution will take care of ~90 % of the cases. Another reason (~7%) for this can be a wrong value for the property AuditTrail.Schema. If this property value is left empty then Stardust will use the connecting users schema. If this is not intended, then the connecting user needs to have access rights to the specified schema and the schema has to contain an audit trail. Other rare reasons are: - the schema has not been created yet - you are connecting to the wrong database or database schema.
