Hello XWiki fellows, in order to customize Curriki for our needs, I need to some functionaiity. I need some GUI modifications, some of which can be done in GWT, some of which have to happen on the server, within velocity or java to call to a lucene-based tool. This tool is already as a webapp, aside of /xwiki, as /SearchI2G What would be the best way to make such a call? - make curriki's java server code depend on SearchI2G's or make a macro. In both cases, most webapp's jars need to be shared which I don't like too much - make a web-call (such as json RPC call), that's the loosest integration - make something else that would use some sort of naming interface (pointers welcome). what do you think?
