Hi,
When I call _emfamh.saveModel(xmlModel, os); //_emfamh is an instance of
AtlEMFModelHandler.

I always get
java.lang.IllegalStateException: Workspace is closed.
at
org.eclipse.core.resources.ResourcesPlugin.getWorkspace(Reso urcesPlugin.java:329)
at
org.eclipse.m2m.atl.engine.AtlEMFModelHandler.saveModel(AtlE MFModelHandler.java:99)
at
org.eclipse.m2m.atl.engine.AtlEMFModelHandler.saveModel(AtlE MFModelHandler.java:65)
at
com.hp.esit.util.mt.TransformationEngine.doTransformation(Tr ansformationEngine.java:285)
at
com.hp.esit.test.mt_test.EngineTest.testTransform2opcragtArg u(EngineTest.java:93)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
.......

By looking into ATL code, I found

In class 'AtlEMFModelHandler', it has a method named protected void
saveModel(final ASMModel model, URI uri, OutputStream out) {....
Which will call IFile file =
ResourcesPlugin.getWorkspace().getRoot().getFile(new Path(uri.path()));

The problem is my ATL program is running in standalone mode, so
ResourcesPlugin is always not loaded which causes that error.

So is it a bug for ATL or I did something wrong?

Thanks a lot

Stephen Yu

I already encountered the same kind of problem and I have submitted a
bug concerning this issue:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=197797

I have attached a patch to the bug that may be integrated soon in the
AtlEMFModelHandler:

I added a new saveModel method allowing to save a model anywhere in the
file system (independently of Eclipse).

Hi Stephen,

Just to say that the patch has been integrated.

Best regards,

Hugo
