Launching patterns from Java program

[Olivier Finot]

Hello,

I am currently using IncQuery and it is working perfectly.

Due to the number of files I have to run my queries on, I wanted to write a Java program to automate the process.
I tried to use the generated matcher (as shown at the bottom of this page : http://viatra.inf.mit.bme.hu/incquery/new/examples/school).
However when I try to run the program, I have the following error message :

Generated EMF-IncQuery patterns cannot be used in standalone Java applications, for now we need the Eclipse Platform running

 The program I wrote is not a standalone application, and I am running it from eclipse, so I do'nt understand the source of the problem.

Thanks in advance for any input you could have on my problem.

Dear Olivier,

first of all thank you for using EMF-IncQuery. Can you give a bit more details on how you are trying to run your applocation?

The error message you encountered is shown if EMF-IncQuery matchers are initiated in an environment where extension points are not available. For example, if you create a java file with Eclipse, but run it as a simple Java Application (static void main) or a JUnit Test, then it will run in a separate JVM and without OSGi bundles. If this would be the case, I suggest changing to running a JUnit Plug-in Test as that provides the easiest entry point to run a selected method.

Best regards,

   Ábel

First of all thanks for your quick answer.

You've guessed right, I was trying to run the program as a Java application.
I understand now the source of this error.
I will try to proceed as you suggest and see if it works.

Dear Olivier,

the RCP application example may be of help to you: http://viatra.inf.mit.bme.hu/incquery/new/examples/application

Hello again,

I looked at this rcp example, but I can't get it to work.

I have probably forgotten something or did it inappropriately, since I am not familiar with creating a rcp from Eclipse.

I just exported the project containing the application as an Eclipse application, and tried to run it using the given command

eclipse.exe -m c:/test/input.ecore - p EClassNames

I have no error, but nothing appears on the console.

It is probably due to some basic thing I did not do, but I have no idea of what it is.
