Using external parameters in ATL [message #1013333]

Hi!!
I am trying to use external parameters with ATL transformations. I am followed the help at ATL_Howtos.

I have also downloaded the org.eclipse.m2m.atl.projectors.xml plugin developed for Juno from docatlanmod.emn.fr and located it in the Eclipse installation folder. In particular, I have trying to copy it to the droppings and plugins folders, even to the ATL proyect folder in my workspace, but it does not work.

I get the error:

Error loading platform:/resource/ATLProyect/InputModels/parameters.xml: org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'null' not found. (platform:/resource/ATLProyect/InputModels/parameters.xml, 1, 13)

Could anybody help me?

Thanks in advance!!

Bea

Hi

Looks like a bad XML file; nothing to do with ATL.

It's always worth using the Sample (Reflective) Ecore Editor to check
whether your files are useable.

Thanks Ed Willink!!

I am trying with the simple parameters XML file available at http://wiki.eclipse.org/ATL_Howtos#How_can_I_tune_the_XML_output_of_ATL:

<parameters>
<param name="param1" value="valueX"/>
<param name="param2" value="valueY"/>
</parameters>

Any clue?

Hi

I have no familiarity with the example, but XML files start with:

<xml ...

Yes, I have tried with something as:

<?xml version="1.0" encoding="UTF-8"?>
<parameters>
<param name="param1" value="valueX"/>
<param name="param2" value="valueY"/>
</parameters>

but nothing...

Hi

I suggest that you learn about basic XML files before trying to tune them.

EMF is trying to load the XML file instead of ATL's XML injector. Note that
you can only use ATL injectors from within Ant scripts.

Hello,

As said by Dennis, you first need to inject your XML file as an XML model (i.e.; a model that conforms to an XML metamodel).
In order to do this, an XML injector is available from http://docatlanmod.emn.fr/ATL/Plugins/org.eclipse.m2m.atl.projectors.xml_0.4.0.jar (built with/for Eclipse Juno but should work with other versions) and can be launched via ATL Ant scripts or programmatically.
If needed, the sources of this plugin are also available from http://dev.eclipse.org/svnroot/modeling/org.eclipse.mdt.modisco/incubation/trunk/am3/plugins/trunk/org.eclipse.m2m.atl.projectors.xml/
