Hello, i have a strange problem using SEAM.
I have a Stateless Session Bean:
@Stateless
| @Name("ProcessStarter")
| //@JndiName("ProcessStarterBean")
| public class ProcessStarterBean implements ProcessStarter{
| ...
|
| public void startProcess(ExeWorkflowCreator creator)
| throws ExeDocFrameworkException {
|
Which is invoked by another stateless Session Bean:
@Stateless
| @Name("menuPrincipal")
| public class MenuPrincipalBean implements MenuPrincipal {
| @EJB ProcessStarter processStarter;
|
| public String startDemoWorkflow2() {
| System.out.println("Starte Demo Workflow 2...");
| try {
| processStarter.startProcess(new DemoWorkflow2());
| }
| catch (ExeDocFrameworkException e) {
| e.printStackTrace();
| }
| return "home";
| }
|
This WORKS.
But now, i want this MenuPrincipalBean to invoke a normal Java Class called "DemoWorkflow" like this:
public String startDemoWorkflow() {
| System.out.println("Starte Demo Workflow...");
| try {
| DemoWorkflow dw = new DemoWorkflow();
| dw.startProcess(dw);
| }
|
with DemoWorkflow being a normal Java class (no sessionbean) which inherits another normal Java class which will then do the method-invocation and the ejb-injection.
DemoWorkflow inherits ExeWorkflowGate:
@Name("ExeWorkflowGate")
| public class ExeWorkflowGate {
|
| @EJB ProcessStarter processStarter;
|
| public void startProcess(ExeWorkflowCreator exeWorkflowCreator)
| throws ExeDocFrameworkException {
| processStarter.startProcess(exeWorkflowCreator);
| }
|
I found out that injection doesnt work here, because the injected beanAttribute is always NULL. Furthermore, i tried everything to invoke the EJB with a JNDI-lookup, but it always says that the Bean is not bound...
The strange thing is that the injection from sessionBean---->sessionBean works, but normal class ----> sessionBean doesnt work.
I also tried to let the DemoWorkflow participate in SEAM Framework by adding @Name("...") annotation...
Anymore suggestions or explanations por favor ?
Thx in advance
