Hi, I have set up http,rmid,reggie,transaction and javaspace services on a mechine and I use the example of RoomBuilder to find the service.But the code can't go well because I found that when go into getService(sdm JavaSpace.class), and when call sdm.lookup(template,null,long.Max),something wrong with it because it can't go the next code.So I think this statement is wrong.But how to solve it? Who can help me?
