[ATL] NPE at org.eclipse.m2m.atl.drivers.emf4atl.ASMEMFModel.loadASMEMFModel(ASMEMFModel.java:320) [message #74895] Tue, 12 February 2008 13:08 Go to next message

Hi,

I'm using ATL from CVS updated today (2008-02-12), mainly to avoid a known error
with the 2.0.0 release build and because the update manager wouldn't let me
install the latest integration build.

Calling ATL from java gives the below exception (the program continues to run).
The simplified code leading to this is:

ByteArrayInputStream[] inModels = {null, null, null, null};
ByteArrayOutputStream[] outModels = {null, null, null, null};
String inTransformation = "replace_cpu";

for (int j = 0; j < 4; j++) {
// initialize outModels[j]
inModels[j] = new ByteArrayInputStream(outModels[j].toByteArray());
}

Transform transform = new Transform();
for (int j = 0; j < 4; j++)
outModels[j] = new ByteArrayOutputStream();
transform.doATLTransformation(inModels, inTransformation, outModels);

with doATLTransformation being:

public void doATLTransformation(ByteArrayInputStream[] inModels, String inTransformation, ByteArrayOutputStream[] outModels) throws IOException {
this.amh = AtlModelHandler.getDefault(AtlModelHandler.AMH_EMF); // crashes here
// ...
}

Is this a known bug or something to worry about?

Eclipse 3.3.1.1 M20071023-1652
EMF 2.3.1.v200709252135

Thanks,
Rene

Hello,

I have same configure as you. Win32 + eclipse 3.3.1.1 + gmf + atl from
cvs. The exception also from
AtlEMFModelHandler emfamh = (AtlEMFModelHandler)
AtlModelHandler.getDefault(AtlModelHandler.AMH_EMF);

I have worked on this many days and still unsolved. It seems the
AtlLauncher example does not work with our configure.

Thank you,
Wong.

Hi,

It seems that AtlEMFModelHandler cannot load the ATL metamodel (a .ecore
file in the src/ folder).

We used to have an ant script to copy .ecore files from src/ to bin/.
However, this script was only necessary on some machines, not on others.
We realized that the problem was with compiler settings: on some
machines, .ecore files were in the exclusion list of files to be copied
from src/ to bin/.

We tried to solve the problem by setting per-project compiler settings.
Then, we removed the ant script, which was making the compilation
process a bit slower.

However, it seems that you may still have this problem. Can you please
check your Java compiler settings? If we have forgotten to set
something, we will add it.


Thanks,

Frédéric Jouault

I updated to todays CVS vesion and added the resource/ directory
containing a.o. ATL-0.2.ecore to bin.includes of org.eclipse.m2m.atl.engine

Now the file shows up in the generated jar file.

Unfortunately this doesn't help solving the exception :(

Any more ideas/howtos?

Could you please give the full exception that you get now? I want to
make sure we have the updated line numbers.

Is putting resources/ in bin.includes enough?
Can you please check whether you really have the following structure in
the jar file?


org/
eclipse/
m2m/
atl/
engine/
AtlEMFModelHandler.class
resources/
ATL-0.2.ecore

The .ecore file must be in the subfolder called "resources" of the
folder containing AtlEMFModelHandler.class. Otherwise,
AtlEMFModelHandler.class.getResource("resources/ATL-0.2.ecore ") will
return null, which leads to an NPE.


Thanks,

Frédéric

The build.properties file of org.eclipse.m2m.atl.engine already has resources/ in bin.includes.

This structure is present in eclipse/plugins/org.eclipse.m2m.atl.engine.jar, which is part of eclipse/plugins/org.eclipse.m2m.atl.engine_2.0.0.datetime.ja r
The latter file does contain the ecore file, but not the class file.
Somehow I get the idea that manually extracting the unversioned jar from the versioned one isn't a good idea, but if I don't extract the file into eclipse/plugins/
these imports won't resolve:

import org.eclipse.m2m.atl.engine.AtlEMFModelHandler;
import org.eclipse.m2m.atl.engine.AtlLauncher;
import org.eclipse.m2m.atl.engine.AtlModelHandler;

Rene

After testing a version from August 2007, I updated to todays HEAD. I cleaned
any remaining files/directories having 'm2m' in their name from my Eclipse directory
and reinstalled. Now the issue seems to be solved, but the call to getDefault() now
seems to hang on something :

this.amh = AtlModelHandler.getDefault(AtlModelHandler.AMH_EMF); // FIXME hangs

In order to get all imports[1] resolved, I manually extracted the org/ directory from
the embedded org.eclipse.m2m.atl.engine.jar into org.eclipse.m2m.atl.engine_2.0.0.datetime.jar
and removed the jar file from the parent archive.

The 'new' archive now has a directory org/eclipse/m2m/atl/engine containing all the class
files and a directory org/eclipse/m2m/atl/engine/resources containing a.o. ATL-0.2.ecore

Rene

If I single-step debug this in the Eclipse debugger, the debugger hangs at a
seemingly random point somewhere in this statement (i.e. two successive debugging
sessions yield two different hanging points).

Could this be an Eclipse / EMF problem? Updating to the latest EMF (2.3.2 20080228)
doesn't help.

Rene

I've attached two stack traces (one from right before executing the statement,
one where it seems to hang (F5-F7-F7 in the debugger).

I've also discussed this a bit on the eclipse.platform newsgroup without
any real results.

Some observations:

* if I debug the program with the source of org.eclipse.m2m.atl.engine
opened, the program doesn't hang but crashes with the exception mentioned
in the subject because it cannot find ATL-0.2.ecore, although this file is
in org.eclipse.m2m.atl.engine/resources. It also cannot find the file if
I put it in the a resources folder in the runtime root directory of the
program.

* Restarting Eclipse without the jar file in the plugins/ directory (forcing
the program to use the source directly) doesn't produce the hang, but crashes
the program because it cannot find ATL-0.2.ecore

* Restarting Eclipse with ATL-0.2.ecore removed from the jar file and without
any sources opened produces the hang instead of the file-not-found crash.

* If I debug the program without the ATL sources opened, it always hangs
(both with and without ATL-0.2.ecore in the jar file).

* Pressing F5-F5-F7 in the debugger makes the debugger hang on a
workbench.runEventLoop() method (iirc).

So although the resource file is in the correct location of the jar file, it
cannot run properly. I've attached the contents of the jar file.

Regards,
Rene

Some more observations:

* Exporting the org.m2m.atl.engine.vm plugin as-is works, but this way Eclipse
cannot resolve "import org.m2m.atl.engine.*" . Two solutions to this problem:
(a) Extract the embedded org.m2m.atl.engine.jar file from the generated
org.m2m.atl.engine_2.0.0-datetime.jar file
(b) Remove the embedded file from its containing jar file and replace it with
its contents (preserving the directory structure)
* When choosing solution (a), Eclipse doesn't hang on the
AtlModelHandler.getDefault() statement, but it gives an exception that it
cannot find ATL-0.2.ecore, and continues running the program with a null
metamodel.
* When choosing solution (b), Eclipse hangs on the AtlModelHandler.getDefault()
statement. I've added some println statements to the getDefault() method, when
using solution (b) it never makes it to here in AtlModelHandler::getDefault() :

public static AtlModelHandler getDefault(String repository) {
AtlModelHandler ret = (AtlModelHandler)defaultModelHandlers.get(repository);
if(ret == null) {
if(AMH_EMF.equals(repository)) {
System.out.println("AtlModelHandler::getDefault() : before");


Any ideas?

Rene
