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
