Class JbpmConfiguration

java.lang.Object
  org.jbpm.JbpmConfiguration

All Implemented Interfaces:: java.io.Serializable

public class JbpmConfiguration
extends java.lang.Object
implements java.io.Serializable
extends java.lang.Object
implements java.io.Serializable

configuration of one jBPM instance.

During process execution, jBPM might need to use some services. A JbpmConfiguration contains the knowledge on how to create those services.

A JbpmConfiguration is a thread safe object and serves as a factory for JbpmContexts, which means one JbpmConfiguration can be used to create JbpmContexts for all threads. The single JbpmConfiguration can be maintained in a static member or in the JNDI tree if that is available.

A JbpmConfiguration can be obtained in following ways:

from a resource (by default jbpm.cfg.xml is used):

 JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();

 String myXmlResource = "...";
 JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance(myXmlResource);

from an XML string:

 JbpmConfiguration jbpmConfiguration = JbpmConfiguration.parseXmlString(
   "<jbpm-configuration>" +
   ...
   "</jbpm-configuration>");

By specifying a custom implementation of an object factory. This can be used to specify a JbpmConfiguration in other bean-style notations such as used by JBoss Microcontainer or Spring.

 ObjectFactory of = new <i>MyCustomObjectFactory</i>();
 JbpmConfiguration.Configs.setDefaultObjectFactory(of);
 JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();

JbpmConfigurations can be configured using a spring-like XML notation (in relax ng compact notation):
