Subject	RE: [ve-dev] Access project from VE Plugin

Hi Rich,
 
Thanks for the prompt reply.
 
Couple of questions please:
 
1. If there is an error/exception
(say while instantiating a class) in target VM, how do I convey it to the
VE?

--- RLK -- You already have done
this. You have done much remote vm work using the proxies in the past.
This is no different. When you do IBeanTypeProxy.newInstance() and exception
is thrown you will receive an ThrowableProxyException in the IDE and from
that you can determine the type of the exception in the remote vm.
 
2. You said I can use JEM to get
IType. I am sorry I did not understand. I have a class name. I want to
find out if the class exists on the Project (in which Visual Classes are
being created) class path. All this I want to do in VE (i.e in my Plugin
class). Is this possible? Could you please point me to relevant documentation?
 
-- RLK -- I'm sure you've done this too. You've
worked with JEM in the past. I'm assuming the project is a VE project so
that JEM would already be enabled on it. JavaRefFactory.eINSTANCE.reflectType(classname,
resourceSetForVE);  where resourceSetForVE is the resource set that
the VE is currently using. It will find the class in the VE's classpath.

Many thanks and regards,
 
Janak

Hi, 

The short answer is you cannot instantiate (i.e. new aclass()) of a class
in a project within Eclipse. It is not meant to be. That is why we use
the remote vm. There are classloader problems, jvm version problems, etc.

As for IType, you can use JEM to get it. For the JavaClass for your class,
use getReflectionType() and cast to IType.

Subject	[ve-dev] Access project from VE Plugin

Dear VE Team,


1. How does one get access to the JavaProject of the Visual Class from
the
VE plug-in?

2. Is it possible to access a particular class from that project and
instantiate it say in the Plugin class?

Thanks and regards,

Janak


PS: I could do the following from the Plugin class, but it doesn't seem
to
be the right way and also I can't  create an instance of IType:

                IResource r =
ResourcesPlugin.getWorkspace().getRoot().findMember("ULCVELocalContainer");
                    
                     
       IProject project = (IProject) r;
                    
                     
       IJavaProject javaProject = JemProjectUtilities.getJavaProject(project);
                    
                     
       try {
                    
                     
                     
  IType type =
javaProject.findType("com.canoo.ve.licensecheck.LoadedClassCheck");
                    
                     
                     
  if (type.isClass()) {
                    
                     
                     
                   System.out.println("Class
found");
                    
                     
                     
  }
                    
                     
       } catch (JavaModelException e) {
                    
                     
                     
  // TODO Auto-generated catch block
                    
                     
                     
  e.printStackTrace();
                    
                     
       }
