Do you honestly expect your web browser to directly talk to your MySQL database?

See http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsClient.html (first paragraph, last sentence)

[vijay]

so, do i need to hv connection code in server side..

[Jens]

Yes, only your server can talk to the database.

Out of the box you can only use JRE classes on client side that are already emulated by GWT. You can see a list of emulated classes at: http://code.google.com/intl/de-DE/webtoolkit/doc/latest/RefJreEmulation.html
