Hello, Could you give us the use case for what you're trying to accomplish? From an initial pass at what your asking would require changes to some of DOTS underlying architecture and functionality . DOTS strives for a small footprint and a dependency on com.ibm.xsp.core would include the servlet API into DOTS. Keep in mind that DOTS is not supposed to open connections on it's own nor is it meant to replace HTTP. Which classes from xsp.core plugins in particular you are trying to use? It may be possible to isolate the scope and bring them into the DOTS runtime. Regards, Paul
