Hi all,
I' m trying to write a blackbox library in Java to add some
functionality to some extra methods.
I have found the following resource:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.m2m/org .eclipse.qvtoml/doc/org.eclipse.m2m.qvt.oml.doc/references/b lackboxing.html?root=Modeling_Project&view=co
I have installed the example at 'Examples/Operational QVT
Transformation/Black-box Library Definition'wizard and downloaded the
project org.eclipse.emf.compare from eclipse svn because it also has an
example of blackboxing at org.eclipse.emf.compare.mpatch.emfdiff2mpatch.
The problem is that the import sentence in the qvto files has an error
whose text is "Cannot find imported compilation unit
'org.mwacsl.SWC2jsp.lib'.
I have been looking for similar problem described in the messages
posted in the eclipse m2m forum, but although I have found some, I
haven't found any answer.
How can I configure in a QVT project where the blackbox libraries
can be found? Is there something similar to Java Build Path to specify
this configuration?
I have created a project that holds the Java code, based on the
example at the wizard. Then I have created a plugin and installed it in
my Eclipse. But I does not work.
Can anyone give me a hint?
Regards,
Toñi Reina

Hi,
finally I found what the problem was. I'm going to report it in case
someone could find it useful.
The problem was that I wrote the class name in the import sentence
org.mwacsl.SWC2jsp.lib.MWACSLUtilitiesLibrary. However, the right
sentence should include the namespace and the unit name.
import m2m.qvt.oml.MWACSLUtilitiesLibrary;
This information can be found in the plugin.xml file attached to the
library project.
<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.7"?>
<plugin>
<extension point="org.eclipse.m2m.qvt.oml.javaBlackboxUnits">
<unit name="MWACSLUtilitiesLibrary" namespace="m2m.qvt.oml">
<library name="MWACSLUtilitiesLibrary"
class="org.mwacsl.SWC2jsp.lib.MWACSLUtilitiesLibrary">
<metamodel nsURI="http://www.eclipse.org/emf/2002/Ecore"/>
</library>
</unit>
</extension>
</plugin>
Furthermore, I have to create the plugin from the MWACSLUtilitiesLibrary
project and installed it.
Regards,
Toñi
