Hi,
I got a problem when I try to call a Java Service in a precondition of a connection.
When I type "service:" the content assist does not show my Java Service that I declared as a Java Extension with its Fully Qualified Domain Name.
I got one source folder having two packages (additionally tried with a services source folder, but did not work either):
org.eclipse.myprojectname.design and
org.eclipse.myprojectname.design.service (having a Java class named DiagramServices.java).
My project name is equal to the first package name from above. So my Java Extension has the FQDN: org.eclipse.myprojectname.design.service.DiagramServices
I started a new Eclipse instance which contained the sample project. Not even that the AQL ínterpreter does not show my service in the content assist, it does also not execute, since a simple System.out.println(...) in the service method does not show up.
Following the steps from the documentation or the tutorial did not help.
Any ideas? I was not able to find any known issues in this field, so I might do something wrong...
Here is my complete service:
package org.eclipse.myprojectname.design.service;
import org.eclipse.emf.ecore.EObject;
public class DiagramServices {
public DiagramServices() {
}
public EObject foo(EObject bla){
System.out.println("------------------------aAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA");
return null;
}
}
Thx!

Hi Maxime,
thx for your reply.
Quote:I noticed a glitch: if i select the interpreter using the auto-completion, then the next call to auto-completion does nothing I need to re-select the property section or to write and delete some characters.
I only found one project attached, but nevermind, I noticed the same glitch as you described.
Quote:If I type service: or aql: then I can continue with auto-completion.
It seems that calling auto-completion just after selecting an auto-completion result and without writing anything between the two calls fails.
Could you try to type the interpreter (service: or aql:) and then call the completion ?
Meanwhile and after approximately 3 hours of searching I discovered, that I added a external Java extension in my plugin.xml which had no Java class in it. That caused the error of the missing content assist contents. When I removed that extension entry, the content assist worked fine again besides the effect you described.
Quote:An additional idea, your service does not require it yet, but you could add the dependancy between your odesign plugin and the plugin declaring the metamodel
I already did that.
Now it works... Thx!
Any idea on that?

Thank you and regards
Alex
