[jBPM Users] - JBPM Graphical Process Designer 3.2 GA is incompatible with
by j2ee4cxw
I just did a fresh installation of MyEclipse Blue Edition (version 7.5), which is based on Eclipse 3.4.2 platform. Then I also installed Subclipse 1.6.x via the Help=>Software updates=>Add/Remove Software.
I have a jbpm-jpdl-3.2.GA download available. I unzipped it and tried to install the GPD via the Help=>Software updates=>Add/Remove Software by pointing to designer directory:
jbpm-jpdl-3.2.GA\designer
The installation went smoothly without any error. However, when I tried to an existing workflow definition, it throws following error.
I want to know any body has encountered this problem. Any suggestion or solution is greatly appreciated.

[Beginner's Corner] - Re: ManyToMany problem
by Wolfgang Knauf
Hi,
I assume that you want to use EJB3/JPA for creating your entities?
In this case, you don't need a role_function entity, and the server will autogenerate the database table for you. The entity "Role" will have a list of "Functions", and the "Function" will have a list of "Role", both connected by annotations.
Pseudocode:
| @Entity
| public class Role implements Serializable
| {
| @ManyToMany (mappedBy="roles")
| public List<Function> functions;
| }
|
| @Entity
| public class Function implements Serializable
| {
| @ManyToMany ()
| public List<Role> roles;
| }
|
Then, your code can access the functions of a role by "myRole.functions.get(x);". The rest is the job of the server and you don't have to care much about it.
Of course, there is quite a bit more to keep in mind. First of all, the two fields should have a getter and setter. More detailed information can be found here: http://www.jboss.org/community/wiki/EJB3relationships
Hope this helps
Wolfgang

[Security] - Re: Authentication succeeded, getCallerPrincipal()=anonymous
by zour
> How does your client access your secured app?
FarmerBeanRemote farmerBean = UserSession.getInstance(getShell().getDisplay()).getMasterDataServices().locateFarmerBean();
| try {
| farmerBean.setAnything(this.actor, id);
| } catch (Exception ex) {
| throw new RuntimeException(ex);
| }
Obtaining of RAP client's user session:
public static UserSession getInstance(Display display) {
| return SessionAccessRunner.getUserSession(display);
| }
Bean lookup:
public FarmerBeanRemote locateFarmerBean() {
| try {
| Object objRef = getInitialContext().lookup(FARMER_BEAN);
| return (FarmerBeanRemote) PortableRemoteObject.narrow(objRef, FarmerBeanRemote.class);
| } catch (Exception ex) {
| throw new RuntimeException("Failed to lookup FarmerBean: " + ex.getMessage(), ex);
| }
| }
The lookup does work, as well as using methods from that bean.
Yet the injected SessionContext isn't aware of the login process.
> Is it a standalone application client
It is a RAP-Client (Rich Ajax Platform) deployed to JBoss. Practically it's running inside a JVM on the server. But any UI elements are rendered in an internet browser (using qooxdoo Javascript-Engine). It's RCP for the web browser.
> Is some servlet/website/web service called?
As far as I understand, a component called ServletBridge does this:
"org.eclipse.equinox.servletbridge.http:
Hooks back into the servlet bridge and proxies requests through to the servlet container to provide an OSGi Http Service."
> How does the client log in?
Via a webpage (login.html) before the RAP-Application starts, see web.xml above.
Maybe this isn't all about JBoss Security, but has something to do with how RAP handles requests, as I found here:
