[jboss-user] [JBoss jBPM] - Integrating JBPM in web application
Hi,
i want to integrate JBPM in my web application. I wrote a servlet which starts a process
with an action handler. But if i deploy this in my Jboss it occurs a
ClassNotFoundException. My Actionhandler is in the same directory and i dont understand
it. Could somebody give me some hints?
My Servlet:
|
| import java.io.IOException;
|
| import javax.servlet.ServletException;
| import javax.servlet.http.HttpServletRequest;
| import javax.servlet.http.HttpServletResponse;
|
| import org.jbpm.JbpmConfiguration;
| import org.jbpm.JbpmContext;
| import org.jbpm.graph.def.ProcessDefinition;
| import org.jbpm.graph.exe.ProcessInstance;
|
| /**
| * Servlet implementation class for Servlet: TestServlet
| *
| */
| public class TestServlet extends javax.servlet.http.HttpServlet implements
javax.servlet.Servlet {
| /* (non-Java-doc)
| * @see javax.servlet.http.HttpServlet#HttpServlet()
| */
| public TestServlet() {
| super();
| }
|
| /* (non-Java-doc)
| * @see javax.servlet.http.HttpServlet#doGet(HttpServletRequest request,
HttpServletResponse response)
| */
| protected void doGet(HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException {
|
| JbpmConfiguration jbpmConfig=JbpmConfiguration.parseXmlString(
| "<jbpm-configuration>"+
|
|
|
| "</jbpm-configuration>");
|
|
|
|
| JbpmContext context=jbpmConfig.createJbpmContext();
|
| try {
| ProcessDefinition processDefinition = ProcessDefinition.parseXmlString(
| "<process-definition>" +
| " <start-state>" +
| " <transition to='s'>" +
| " <action name='action'
class='MyActionHandler'>"+
| " <message>Going to the first state!</message>"+
| " </action>"+
| " </transition>"+
| " </start-state>" +
| " <state name='s'>" +
| " <transition to='end' />" +
| " </state>" +
| " <end-state name='end' />" +
| "</process-definition>"
| );
|
| ProcessInstance processInstance =
| new ProcessInstance(processDefinition);
|
| // After construction, the process execution has one main path
| // of execution (=the root token).
| processInstance.signal();
|
| // Also after construction, the main path of execution is positioned
| // in the start-state of the process definition.
|
| // Let's start the process execution, leaving the start-state
| // over its default transition.
|
| // The signal method will block until the process execution
| // enters a wait state.
| processInstance.end();
|
| }finally{
| context.close();
| }
| }
| protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
|
| }
| }
My ActionHandler:
| import org.jbpm.graph.def.ActionHandler;
| import org.jbpm.graph.exe.ExecutionContext;
|
|
| public class MyActionHandler implements ActionHandler{
|
| /**
| *
| */
| private static final long serialVersionUID = 1L;
|
| public void execute(ExecutionContext arg0) throws Exception {
|
| System.out.println("######################");
| System.out.println("Mail senden");
| System.out.println("######################");
| }
|
| }
Is there a special File hierarchy which i have to use?
