[asert@xxxxxxx (asert)]

I have two web projects,one is old page style,another is new page style,
in other words:they use same servlets process data,only jsp is different;
now I have to maintain same code on the two projects;

I created another projects and put these servlets in it,but I dont know how
to config eclipse so that complie servlets to web-inf/classes of these two 
web projects;

how to do? or anybody has another good idea make my work less boresome?
