no output from workflow called by java - action - debug action calls? [message #138446]

Hi

I'm on the last leg - packaging my plugin

I have a plugin which is trying to run a mwe workflow
(the workflow runs in project explorer right click as expected)

When I export my plugin and load it, then run my action, the action
is called as evidenced by org.eclipse.jface.dialogs placed in my code.

I have checked that the workflow urls I am using point to resources
actually exist but I don't seem to be getting any output. Normally it
takes about 11 to 23 secs to run the workflow but through java it just
skips through

I'm selecting a gmf output file as my model file.

This is how I am calling my action (no exceptions thrown)

ngossModel is my GMF model file

Is there any better way of getting debug info from something called
from an action. The only way I can check things is via placing jface
dialogs in my code. Not sure how to use debugger on an action if
possible? (no debug or console)

regards
Steve

public void run(IAction action) {

String message = Messages.RunTransformationAction_message;

MessageDialog.openInformation(getShell(), title, NLS.bind(message,
file.getFullPath()));

org.eclipse.jface.dialogs.MessageDialog.openInformation(getS hell(),

> I have a plugin which is trying to run a mwe workflow

And now the fun begins. I don't know is there any new solution for old
problems with "running workflow from code" in Eclipse Xpand.
There are workarounds for oAW version so I will point to them.

Firstly, console is quite important to know what is happening. So you
need to set it up and running. It would be interesting to know what is
the error on the console.

I guess that you will have some errors connected with UML plugin on you
console or another errors that are caused by different handling of
execution context in workflow runned externally and from code (normal
classpath or equinox managed classpath and resources).

Both problems can be solved and you can start looking for solution here:
https://opensource.luminis.net/wiki/display/SITE/oAW+Workflo w+from+Eclipse+Plugin
(check the links, there too)

But as I said before, maybe new solution is available. So you can also
ask specific question (In a new topic) on this news group.

You can debug only Java code in your setting, you just need to run you
eclipse application in debug mode, from the eclipse instance where you
develop you plugin. You will not be able to debug Xpand/Xtend if you
running it form code.

Hi Bill,

you're saying that you don't get any feedback (exceptions, or the like)?
This really is strange.

Looking at the code I noticed, that given you're running in an OSGi
environment you'll have to configure the ResourceLoader before running
the Workflow like this:

ResourceLoaderFactory.setCurrentThreadResourceLoader(new
ResourceLoaderImpl(getClass().getClassLoader());

But you should at least get some ClassNotFouncExceptions.

Hi Sven

I don't know if you saw one of my other posts. I'm running on mac env.
There was a previous issue with a missing plugin com.ibm.icu when I was
testing in the workbench mode with runtime config. Without this plugin
I was getting the generator terminating with no output. This almost
drove me mad until out of curiosity I tried running in windows. On doing
this I received an error in the console about the missing the above
plugin, so there can be some funny things happening with different OS's!
(not suggesting that's the issue here - checked my dependencies)

may test on a pc though to see what happens!

I did look at some of the code in cvs re
WorkflowFacade(string.mwe).run()

I tried running that, I found that it was validating my model file (I
got validation errors in a pop up jface dialog against an old invalid
model, when I ran on correct model I got an error in a dialog saying
illegalArgumentException - couldn't load my mwe file

(I got the same error when I ran against a corrected version of my model
file - just an enum format change). This implies that the error is
occurring after the Reader ?

There doesn't appear to be a way to pass in user selected model files
and slots using this method though.

Just to clarify, the reason I'm running as an action from eclipse is
that if a user is creating models in a project of their choice, I want
to be run my workflow on that file and put the output in their local
project folder

Thanks again for the feedback, I'll try some of your suggestions

regards
Steve

I previously had my gmf diagram and my ui containing my workflow
contained in a single plugin feature which I exported to my local host
eclipse.

I got no output, if I remove it, restart, just install the ui component
directly, restart then I get an error

DiagnosticWrappedErrorException
org.eclipse.emf.ecore.xmi.PackageNotFoundException
package with uri 'http://www...blah' not found

ie it can't find the ecore files referenced in my workflow?

Thanks all

I rewrote the ui plugin without OSGi gubbins and it works, phew!

The issue is not the missing classes, but some problems with Java 6 (or
was it 5, I don't remember) on a mac.
It for some reason runs the main code in a new thread (not the main
thread). Any exceptions which are thrown will never end up in the console.
I also found that in these cases, the current thread classloader is
sometimes not set, which as well causes strange errors.

If it says 'couldn't load *.mwe file' it is that WorkflowRunner can't
find a *.mwe file for the passed URL.

But you're passing slotContents.
Why do you think that this is not possible?

It seems like the URL is not right.
