Onepagechekout sql exception

[Jaipal]

Hi, In case of onepagecheckout I need to write a  sql query inside java class but I am getting exception at import package  java.sql.*.I am using gwt  kit provided by konakart to modify & check onepagecheckout .what is reason even packages like  java.util.*,java.io.*  work well.

The reason is that the java code gets converted to java script and runs in your browser.
