Subject Re: camel-swagger in karaf? not yet....

Ok,  I've spent the bulk of my day on this, and have met with some success.

There are a few other gotcha's trying to get swagger to run from karaf.  (some issues were
fought based on my application, for example, i was using guava 18, however swagger brings
with it guava 15 creating some dependency chain nightmares...)

The first "real" issue was with the RBAC setup in newer karaf versions.  The DefaultCamelSwaggerServlet
tries to execute "dumpRestsAsXml" and karaf will not allow it.

To fix this I created etc/ with contents:

dumpRestsAsXml = *

This should probably go into the camel-swagger feature?

Second problem, my application has multiple camel servlets, and the class mentioned above
essentially just picks the last one it enumerates, unless the camelId init-param is set on
the servlet config.

So to get DefaultCamelSwaggerServlet to pick the correct mbean to invoke dumpRestAsXml, I
had to add this to my web.xml inside the DefaultCamelSwaggerServlet definition:


where elnk-jhm-main is the name of my camel context containing my rest routes

NOTE: the quotes were required here.

camelId is currently not documented on the wiki page, and it seems like DefaultCamelSwaggerServlet
should probably be modified so that it strips the quotes when doing the .equals on camelId,
so that the param-value doesn't need quotes.

I got all this working, and was a little surprised to just see a json output (was expecting
the swagger web ui).  So i built and ran the camel tomcat servlet example which has swagger
configured, and upon snooping around that project realized you still need to do a bunch of
additional work to actually include the swagger ui into your project (all done in the pom.xml
of that example project)  

This is fine, and apparent to me now, but my expectation going into this was more along the
lines of once I had the camel-swagger stuff configured in my servlet, bam, i would have swagger
running.  It might be worth updating the wiki to mention the pom.xml configs for downloading/extracting/installing
swagger are required still.

All in all I made good progress, I'm willing to either help with the documentation updates
or the karaf feature config if any help is needed.  please let me know!
