Possibly odd RMAP question [message #649494]

I'm trying to write a RMAP provider for a certain type of component, but
can't seem to get it all right.

I have a plugin A containing only documentation (i.e. no Java-code). The
plugin is delivered in the form of a jar-file. If I unpack the jar, I
can resolve it using the same way as I resolve everything all other plugins:

<rm:provider componentTypes="osgi.bundle"
readerType="url.catalog" source="false" resolutionFilter="">
<rm:uri format="{0}/plugins/{1}">
<bc:propertyRef key="hubble.root.url"/>
<bc:propertyRef key="buckminster.component"/>
</rm:uri>
</rm:provider>

Now, I would like to avoid having to unpack the jar, and instead get the
RMAP to resolve the plugin directly. If I try to just edit the "uri"
field like this:

<rm:searchPath name="docjars">
<rm:provider componentTypes="osgi.bundle" readerType="url.catalog"
source="false" resolutionFilter="">
<rm:uri format="{0}/docjars/{1}.jar">
^^^^^^^^
<bc:propertyRef key="hubble.root.url"/>
<bc:propertyRef key="buckminster.component"/>
</rm:uri>
</rm:provider>
</rm:searchPath>

but then Buckminster complains with the following error:

[java] ERROR [0002] : Resolution attempt ended with
exception: Provider
url.catalog(file:/home/jesperes/dev/eclipse//docjars/com.web works.eclipsehelp.Eclipsetest.jar):
Missing CSpec source required by component type osgi.bundle

Is it possible to do this?

Instead of specifically adding jar to your uri as in:

<rm:uri format="{0}/docjars/{1}.jar">

Have you tried adding jar to the list of component types? Because since you specify your component type as osgi.bundle and jar is found, there is a mismatch. You can also append "jar" to your existing component types and it will match both:

<rm:provider componentTypes="osgi.bundle,jar"
readerType="url.catalog" source="false" resolutionFilter="">
<rm:uri format="{0}/plugins/{1}">
<bc:propertyRef key="hubble.root.url"/>
<bc:propertyRef key="buckminster.component"/>
</rm:uri>
</rm:provider

Alex

No difference. I still get the "Missing CSpec source required by
component type osgi.bundle", which to me looks like it actually finds
the plugin, but is unable to generate the cspec directly from the jar.
