Over the past while we have started making RFPs available at OSGi for public comments before they are finalized and voted on. This has worked really well for the OSGi Cloud RFP and the OSGi/CDI integration RFP.
RFP 143 OSGi Connect
The people at PojoSR have done some great work in showing how you can use OSGi Services in cases where you may not want to take on OSGi modularity (yet). RFP 143 captures requirements for creating a specification around this. The RFP can be found here: RFP 143.
RFP 150 HTTP Service Updates
The OSGi HTTP Service is widely used and it provides a very nice programming model for sevlets in an OSGi environment. However the specification is in need for an update to modernize it in relation to the Servlet spec itself. Additionally, the whiteboard pattern is introduced for servlet. You can find the RFP here: RFP 150.
RFP 151 Declarative Service Updates
A variety of updates are proposed to the Declarative Services specification. They can be found in RFP 151.
RFP 152 EJB Integration
EJB integration with OSGi has been done at Apache Aries and Glassfish. Other appservers such as JBoss and others also provide some form of interaction between EJBs and OSGi. This RFP aims a writing a specification for this integration to make OSGi-enabled EJBs portable. You can find the RFP here: RFP 152.
If you have thoughts or opinions about the above topic, have a read of the RFPs and put your comments on the associated bugs.
