JDBCWorkflowFactory

public class JDBCWorkflowFactory extends XMLWorkflowFactory implements FunctionProvider(Code)

Workflow Factory that stores workflows in a database. The database requires a property called 'datasource' which is the JNDI name of the datasource for this factory.

Also required is a database table called OS_WORKFLOWDEFS with two columns, WF_NAME which contains the workflow name, and WF_DEFINITION which will contain the xml workflow descriptor, the latter can be either a TEXT or BINARY type.

Note that this class is provided as an example, and users are encouraged to use their own implementations that are more suited to their particular needs.
