Re: [Topcased-users] Acceleo java service: "Class ... Couldn't be found in the classpath of the bundle containing module ...emtl"

In fact, I face 2 different problems :

Trying to run your test:

"non fatal" log4j NPE in LogFilter.isLoggable (whereas there is no explicit log4j reference in your test -> it seems to be called by Eclipse)
"fatal" OutOfMemoryError: PermGen space (?)

The "com.google.common.base.Predicate not found" comes from a simple Java program I've written, in order to simply run your generator (without using Junit). I've created a new Java project for it, and I guess I miss some runtime dependencies. => how did you resolve the dependencies of your test project?

By the way, my initial problem was to print out current date => I've just found that it is possible to use class ReportingUtil from org.topcased.olc.reporting :

[import org::topcased::ocl::reporting::utils::ReportingUtil/] ... [let o : EObject = ...] [o.getCurrentDate()/] [/let]

Hi thierry.

you can remove any Log4j stuff, this is only for logging purpose ( i d'ont remember my example used it )

For Google predicate class, Acceleo requires it, but it should be already present in your installation.

Go to "run configurations" then "plug-ins" tab, then click on "Add required" to dd the missing plugins to your Eclipse runtime.

Hi Stéphane,

I've tried your example, but I can't run it (NPE because of log4j missing I guess, then out of memory exception).

I've tried to make up a simple java runner for the generation, and I can't have it work (class not found: com.google.common.base.Predicate -> I don't know what google is doing here...). Any idea?

By the way, all I need for the moment is the date. So, is there another way to get current date with acceleo?

Regards,
Thierry.

Thierry, i haven't tried the workaround for the runAs -> acceleo plugin application.

you can try to ask to the acceleo team in its forum : http://www.eclipse.org/forums/index.php/f/24/

Ok. Thank's for the details.
Anyway, is there a way to do the same explicit registering with
the standard Eclipse launcher: I mean with ->Run As -> Acceleo
plugin application ?
Otherwise, I'll try a programmatic Java launcher, as in your the
unit test...

Regards,
Thierry.

it is described in the attached sample of the bug.

owever, there is my workaround :
AcceleoServicesRegistry.INSTANCE.addServiceClass("plugin_id",
"QualifiedNameOfServiceWithoutExtension");

Yes, it seems to be the same problem.
Now, in practice, how do you register yourself the service
"manually"?

Thanks,
Thierry Lafage.

Maybe you are facing this bug :
https://bugs.eclipse.org/bugs/show_bug.cgi?id=406528

a workaround i found is to register myself the service.

Hi Topcased users,

I've been stucked by a problem with acceleo Java
services for a
long time. I've tried several things to make it work,
but I didn't
manage...
So, here is the problem: I want to define a basic
service in Java
and I want to call it from a query in an .mtl file.
I strictly followed the Acceleo Tutorial : I defined
a Java source
"Toto.java" where I put my java class, then I defined
a tutu.mtl
service file where I defined the queries associated
with the Java
service. Then, I defined another .mtl file, the main
module,
main.mtl, where the queries from tutu.mtl are called.
I added the package of my Java service Toto in the
MANIFEST.MF and
I assured it is in the runtime classpath.
When I run the main.mtl (with Acceleo plugin application
(default)), I get this error:
"Class pkg.name.Toto Couldn't be found in the
classpath of the
bundle containing module tutu.emtl"

At first, I was running Topcased-5.1. So I updated to
Topcased-5.3.0 -> same problem.
Then I saw that the acceleo version is not the latest
one in
Topcased-5.3.0. So I updated to Acceleo 3.4.1 -> same
problem.
With this latest config, I first tried to put
Toto.java and
tutu.mtl in a different package, name "services" as
recommended in
the tutorial. Then, I put all files in the same
package -> same
problem.

I searched the Internet for this problem and I found
little
information. It seems that the problem has been fixed
by the
latest acceleo releases, but I can't fix it out.

Any clue would be greatly appreciated (I can give
more details if
needed).

Regards,
Thierry Lafage.
