Hi Paul,

AFAIK, Dims is using org.osgi.service.http.HttpService implementation 
that comes with Equinox. According to this specification, it support 
registering servlets and resource (static). The prior interface is also 
implemented in Felix too. Both Equinox and Felix uses Jetty to implement 
this.

According to the responses I got from Felix dev mailing list, there is 
no notion of including JSP support to HttpService in R4. I am forwarding 
the responses I got from Felix dev [1]. They have proposed a way to 
integrate JSP support in Tomcat, but in order to achieve this, app 
server JSP compiler needs to support the notions of OSGi.

Thank you

Saminda
