Hi,

Acceleo version: 3.0.1.v201009150438

Problem observed:
I have implemented a java service that is called from my .mtl file. This java service uses methods from a third party library, mylib.jar.

Location of mylib.jar is specified in Acceleo project's classpath. This location also appears in Classpath tab in Run Configuration under "User Entries -> <my project name> (default classpath)".

If Acceleo project is executed standalone (Runner: Java Application) then java service runs perfectly fine.

If, however, Acceleo project is executed as Acceleo Plug-in Application, it give ClassNotFoundException for the classes used in java service, from mylib.jar.

Am I missing something here?

Thanks
Anil

Hi,

Has anyone else faced this issue, or is this expected behavior..?
I have been trying to get answer to this, but could not see any such existing question.

Thanks
Anil

Hi,

I' think your jar is not in the runtime classpath.
For solve your problem, open the MANIFEST.MF go to the "Runtime" tab and add your mylib.jar reference to the "Classpath" list (right botom corner) .

You can also write directly in the manifest file by adding the following lines:
Bundle-ClassPath: .,
mylib.jar


Best regards
