jbpm使用要点

JbpmConfiguration config = JbpmConfiguration.getInstance();

JbpmContext jbpmContext = config.createJbpmContext();

TaskMgmtSession session=new TaskMgmtSession(jbpmContext.getSession());

List tasks=session.findTaskInstances("gaga");

public class TaskAsignMent implements AssignmentHandler {

public void assign(Assignable assignable, ExecutionContext executionContext)

throws Exception {

assignable.setActorId("gaga");// assignable就是工作项

}

}

public class ProcessImageServlet extends httpservlet {

private static final long serialVersionUID = 1L;

protected void doGet(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

long processDefinitionId = Long.parseLong( request.getParameter( "definitionId" ) );

JbpmContext jbpmContext = JbpmContext.getCurrentJbpmContext();

ProcessDefinition processDefinition = jbpmContext.getGraphSession().loadProcessDefinition(processDefinitionId);

byte[] bytes = processDefinition.getFileDefinition().getBytes("processimage.jpg");

OutputStream out = response.getOutputStream();

out.write(bytes);

out.flush();

// leave this in.it is in case we want to set the mime type later.

// get the mime type

// String contentType = URLConnection.getFileNameMap().getContentTypeFor( fileName );

// set the content type (=mime type)

// response.setContentType( contentType );

}

}

JbpmConfiguration config = JbpmConfiguration

.parseResource("jbpm.cfg.xml");

config.createSchema();

config.close();

JbpmConfiguration config = JbpmConfiguration.getInstance();

JbpmContext jbpmContext = config.createJbpmContext();

TaskInstance taskInstance=jbpmContext.getTaskMgmtSession().loadTaskInstance(taskId);

String offshoot="" + param.get(Constant.OFFSHOOT);

//taskInstance.end(offshoot);

taskInstance.end();

jbpmContext.save(taskInstance);

jbpmContext.close();
