Re: [equinox-dev] Servlet API support
Simon,

I am aware the the OSGi HttpService has a minimum expectation of Servlet API support which is being met by the equinox service. My point is, however, that the OSGi versioning and dependency resolution is broken here since I express a dependency on the desired version but still can't find out until runtime that my selection of bundles was incorrect.

Does this appear as a limitation of OSGi or is there something smarter that equinox can do in terms of declaring exports in its manifest?

Thanks for the jetty heads up!

Nikunj.

The org.eclipse.equinox.http bundle provides just such a minimal implementation and is tiny in terms of its overall size.
The trade-off is that it doesn't support the Servlet API beyond 2.1. Changes were put in the code so that it would still be able to resolve against a higher Servlet API albeit throws UnsupportedOperationExceptions for the use of those methods.
 
If you want an Http Service that supports Servlet 2.4 you can use the Jetty based implementation e.g. org.eclipse.equinox.http.jetty.
See http://www.eclipse.org/equinox/server/http_in_equinox.php (I'd recommend using the teamset to collect up the right dependencies)

Subject: [equinox-dev] Servlet API support

The equinox bundle org.eclipse.equinox.servlet.api_1.0.0 containing the servlet API says that it exports javax.servlet; version =2.3 and javax.servlet.http; version =2.3.

However, none of the >2.1 servlet API features work when using org.eclipse.equinox.http_1.0.100 bundle and result in
java.lang.UnsupportedOperationException: HttpService only supports servlet 2.1 specification.

Can someone throw light on the reason behind such behavior?
