} , have added mysql-bin.jar connector in war/web_inf/lib/ , getting compilation error

17:39:52.353 [error] [a] line 28: no source code available type java.sql.statement; did forget inherit required module?

i need know why getting error , how can rectify it

you cannot use server-side code (java.sql.* in case) in gwt client side modules.

you should make rpc call server. server callback should fetch data database, , send gwt client.
