now i am continue to my test.
i want to know how to activate a message executor?
| <process-definition name="sub">
| <start-state name="start">
| <transition to='auto' />
| </start-state>
| <node name="auto" async='true' >
| <action class="example.processmodel.NodeExecuteHandler" />
| <transition name="endtran" to='end' />
| </node>
| <end-state name="end" />
| </process-definition>
|
|
| JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
| jbpmContext.deployProcessDefinition(processDefinition);
|
|
| /////////////////////////////////
| Token token= processInstance.getRootToken();
| System.out.println(token.getNode().getName());//START
|
| token.signal();
| System.out.println(token.getNode().getName());//AUTO
| jbpmContext.save(processInstance);
| jbpmContext.close();
|
| public class NodeExecuteHandler implements ActionHandler {
|
|
| public void execute(ExecutionContext executionContext) throws Exception
{
| // TODO Auto-generated method stub
| System.out.println("NodeExecuteHandler");
| executionContext.setVariable("bianliang","value1");
| executionContext.leaveNode("endtran");
| }
|
| }
|
It seems the example.processmodel.NodeExecuteHandler has not been execute as i
could not see the system out.And i looked up in the database table
jbpm.jbpm_message and saw
1, 'N', 'CMD_EXECUTOR', '', 0, 1, '', , 2, '',
the config:
| static JbpmConfiguration jbpmConfiguration = null;
|
| static {
| // An example configuration file such as this can be found in
| // 'src/config.files'. Typically the configuration information is
in the
| // resource file 'jbpm.cfg.xml', but here we pass in the
configuration
| // information as an XML string.
|
| // First we create a JbpmConfiguration statically. One
JbpmConfiguration
| // can be used for all threads in the system, that is why we can
safely
| // make it static.
|
| jbpmConfiguration = JbpmConfiguration.parseXmlString(
| "<jbpm-configuration>" +
|
| // A jbpm-context mechanism separates the jbpm core
| // engine from the services that jbpm uses from
| // the environment.
|
| " <jbpm-context>" +
| " <service name='persistence' " +
| "
factory='org.jbpm.persistence.db.DbPersistenceServiceFactory' />" +
| " <service name='message' " +
| "
factory='org.jbpm.msg.db.DbMessageServiceFactory' />" +
| " </jbpm-context>" +
|
| // Also all the resource files that are used by jbpm are
| // referenced from the jbpm.cfg.xml
|
| " <string name='resource.hibernate.cfg.xml' " +
| " value='hibernate.cfg.xml' />" +
| " <string name='resource.business.calendar' " +
| "
value='org/jbpm/calendar/jbpm.business.calendar.properties' />" +
| " <string name='resource.default.modules' " +
| "
value='org/jbpm/graph/def/jbpm.default.modules.properties' />" +
| " <string name='resource.converter' " +
| "
value='org/jbpm/db/hibernate/jbpm.converter.properties' />" +
| " <string name='resource.action.types' " +
| " value='org/jbpm/graph/action/action.types.xml' />" +
| " <string name='resource.node.types' " +
| " value='org/jbpm/graph/node/node.types.xml' />" +
| " <string name='resource.varmapping' " +
| " value='org/jbpm/context/exe/jbpm.varmapping.xml' />" +
| "</jbpm-configuration>"
| );
| }
|

application server. thanks for help~
