Hey all,I try to start my Process programmatically, not in Activiti Explorer.The process should start with a form: <startEvent id="theStart" activiti:formKey="resources/bookorder.form" />What should I do, to see a form in browser.I start and deploy a process in a servlet. This is a code:
public class ActivitiTestServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
RepositoryService repositoryService;
RuntimeService runtimeService;
FormService formService;
/**
* @see HttpServlet#HttpServlet()
*/
public ActivitiTestServlet() {
super();
// TODO Auto-generated constructor stub
}
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
try{
buildProcessEngine();
response.setStatus(200);
PrintWriter writer = response.getWriter();
writer.println("<html>");
writer.println("<head><title>Hello World Servlet</title></head>");
writer.println("<body>");
writer.println(" <h1>Hello World from a Sevlet!</h1>");
writer.println("<body>");
writer.println("</html>");
writer.close();
}
catch (Exception e){
System.out.println("Fehler: " + e);
response.setStatus(404);
}
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
}
public void buildProcessEngine(){
ProcessEngine processEngine = new ProcessEngineBuilder()
.configureFromResource("activiti.cfg.xml")
.buildProcessEngine();
getServices(processEngine);
deploy();
}
public void deploy(){
String barFileName = "D:/workspace/ActivitiTestServlet/src/barFiles/bookorder.bar";
ZipInputStream inputStream = null;
try {
inputStream = new ZipInputStream(new FileInputStream(
barFileName));
} catch (FileNotFoundException e) {
System.out.println(e);
e.printStackTrace();
}
repositoryService.createDeployment().name(barFileName)
.addZipInputStream(inputStream).deploy();
runtimeService.startProcessInstanceByKey("bookorder");
}
public void getServices(ProcessEngine processEngine){
repositoryService = processEngine.getRepositoryService();
runtimeService = processEngine.getRuntimeService();
formService = processEngine.getFormService();
}
}
Can I put the rendered HTML-String in the writer?I tried to get the form with code: writer.println(formService.getRenderedStartForm("processDefId"));Is it correct? How get I a processDefinitionId?Best regardsAlexej
