Troubleshooting
Problem
When trying to load resources from the Eclipse Modeling Framework (EMF) Editor of IBM® Rational® Software Architect (RSA) using an URI containing a pathmap (like
[] pathmap://MYPATHMAP/MyLibModel.uml [
]) the following exception may be raised:
[]
java.net.MalformedURLException: unknown protocol: pathmap
at java.net.URL.
]
Cause
A possible cause is that the pathmap is not recognized. Adding it to Window > Preferences > Modeling Path Maps will not solved the problem.

In v7, the pathmap for this editor has to be declared in a plugin extending org.eclipse.emf.ecore.uri_mapping
(see attached project):
1) Create a plugin project
2) Create a subfolder and copy into it all files that have to be found using your pathmap
3) Open the plugin.xml with the Plug-in Manifest Editor
4) On the Dependencies tab, ensure that the following plugins are added:
- org.eclipse.ui
- org.eclipse.core.runtime
- org.eclipse.gmf.runtime.emf.core
5) On the Extensions tab, add the extension
org.eclipse.emf.ecore.uri_mapping
6) Right-click on it and select New > Mapping
7) Enter, for example,:
source=pathmap://MYPATHMAP/
target=platform:/plugin/PathMap14503/Test/
Where Test is the subdirectory created in Step 2)
8) On the Build tab, ensure that the subdirectory created in Step 2 and all the nested files are selected under Binary Build
9) Save all
10) Run the plugin as an Eclipse Application
11) Open an EMF or GMF model
12) Right-click on the editor and select Load Resource
13) Enter an URI using the declared pathmap (like
pathmap://MYPATHMAP/MyLibModel.uml
)
