Class CommandExecutorSLSB

java.lang.Object
  org.jbpm.enterprise.impl.CommandExecutorSLSB

All Implemented Interfaces:

java.io.Serializable, javax.ejb.EnterpriseBean, javax.ejb.SessionBean

public class CommandExecutorSLSB
extends java.lang.Object
implements javax.ejb.SessionBean

Stateless session command executor.

Configuration

In order to provide commands an environment in which to run, the command executor builds an environment factory from a configuration file loaded as a classpath resource. The environment entry ConfigurationResource specifies the name of the resource to access; the default is enterprise.environment.cfg.xml.

JNDI-bound environment factory

To avoid parsing the configuration file multiple times, the command executor attempts to bind the environment factory to the name specified in the EnvironmentFactoryName environment entry, defaulting to java:jbpm/EnvironmentFactory. If the binding fails, the command executor will still work; however, each instance will build its own environment factory from the configuration.
