var sql ="Select ......." + document.formname.comboname.value + "...");
- Now you are passing the "sql" query value to the server (may be through some hidden variable) and executing it in server .

- Displaying the result back in JSP.
That helped?
P.S. Do remember that the Javascript code is executed at the client side and Java code at the server side.
