Incorrect access to model in ubuntu [message #507126]

Hi, I am trying to validate a model using evl in Ubuntu 9.04 and Eclipse Galileo. When validating I get a message that says

Resource 'xxx' does not exist. (xxx is a file path)

The file exists and debugging the execution I found that in the class EmfModel the instruction this.modelFileUri = EmfUtil.createURI(modelFile); returns the URI with "platform:/resource" before the valid path.
Inside the method createURI() I see that these lines are commented:

// Handle paths that start with / under Unix e.g. /local/foo.txt
//else if (OperatingSystem.isUnix() && s.startsWith("/")) {
// return URI.createFileURI(s);
//}

Could be my problem because that?

Best regards,
Raul

Hi Raul,

Are you launching the validation through the UI or through Java code?

Cheers,
Dimitris

Hi Dimitrios,

I am working with Raul in the same project. The validation is launched through java code.

Best regards,
Hector

Hi Hector,

To be on the safe side when loading EMF models from Java, you should use
the complete URI (e.g. file:/foo/bar.model,
platform:/resource/foo/bar.model)

What do you mean with "safe side"?

Let's specify a little more the problem.

I call the evl validation through java using a plugin, and in order to do that I launch a second Eclipse instance where the models are. In Windows I have never had this issues (still haven't) but when running the tests from Linux I get this error. In Windows createURI does not add the prefix "platform:/resource", does it mean it has no need of keeping in the safe side?

/foo/bar.model is an absolute path, doesn't it? Or should I give workspace relative paths in Linux?

Many thanks,
Hector

I reply to myself:

I have made it work changing the given path from an absolute path to a workspace relative path. Now, using the epsilon OperativeSystem utilities I change the path of the model depending on the S.O. of the computer.

Is this the correct way or would it be fixed?

Best regards,
Hector
