[jboss-user] [JBoss jBPM] - While starting process from a servlet error arise
Hi!
I created a servlet to start the standard jbpm process "websale". I simply
deployed it to the server. This is the code:
| import java.io.IOException;
|
| import javax.servlet.ServletException;
| import javax.servlet.http.HttpServletRequest;
| import javax.servlet.http.HttpServletResponse;
|
| import org.jbpm.graph.def.ProcessDefinition;
| import org.jbpm.JbpmConfiguration;
| import org.jbpm.JbpmContext;
| import org.jbpm.db.GraphSession;
| import org.jbpm.graph.exe.ProcessInstance;
|
| public class HelloWorld extends javax.servlet.http.HttpServlet implements
javax.servlet.Servlet {
| static final long serialVersionUID = 1L;
|
| private void startProcessDefinition() {
| String processDefinitionName = new String("websale");
| JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();
| JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
| try {
| GraphSession graphSession = jbpmContext.getGraphSession();
| ProcessDefinition definition =
graphSession.findLatestProcessDefinition(processDefinitionName);
| ProcessInstance instance = definition.createProcessInstance();
| instance.signal();
| jbpmContext.save(instance);
| } finally {
| jbpmContext.close();
| }
| }
|
| public HelloWorld() {
| super();
| }
|
| protected void doGet( HttpServletRequest request,
| HttpServletResponse response)
| throws ServletException, IOException {
| startProcessDefinition();
| }
| }
But when I execute it the following error comes up:
anonymous wrote : org.jbpm.JbpmException: couldn't find process definition
'websale'
| org.jbpm.db.GraphSession.findLatestProcessDefinition(GraphSession.java:170)
| HelloWorld.startProcessDefinition(HelloWorld.java:24)
| HelloWorld.doGet(HelloWorld.java:43)
| javax.servlet.http.HttpServlet.service(HttpServlet.java:697)
| javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
| org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)
The process is deployed and works fine.
I tried to configure the hibernate.cfg.xml (located in the WebContent directory) file and
also tried to find some help in the docu.
Hope you can help me.
Bye
