This time I didn't use applet. I deployed the app onto the server and it was called as a bean. I had geoapi-nogenerics-2.1-M2.jar, gt2-referencing-2.3.2.jar, gt2-epsg-hsql-2.3.2.jar, hsqldb-1.8.0.1.jar and jsr108-0.01.jar in my class path. Before I deployed it worked well locally but when I ran the web it reported that the epsg code couldn't be found. Do I need do something on the server side?
