Hi Greg,
Finally I found someone who has been working on MySQL in GWT. I am working
on a project that involves both. But I am kind of stuck with the similar
issue. Can send a sample example to better understanding of GWT and MySQL.
I am using GWT-RPC.

Thanks Joe,
It's just that I've had a very bad experience with Mochahost. You don't
know want you get until you try it, though I guess it's my fault for trying
to go too cheap This time I wanted to choose a hosting with a little
bit more of criteria...

Can anyone suggest me a good hosting that supports gwt and mysql?
I'm with mochahost now but it's not acceptable how incredibly slow it is.
also their support group is not of much help.
Thanks,

Just about any host. Nothing special needed for GWT. If you're using a Java
backend, then you'll need a host that can support a war/ear deployment or
get your own VPS. I usually use AWS, but you could do Digital Ocean or
DreamHost too. Just Google for hosting.

since the db-connection needs to happen on the server-side of your
GWT-application, you can use every jdbc-example being done with
MySQL out there as reference.
Objectify works really well for me to query within GAE and return DTOs to
GWT.

I doubt that your mySQL JDBC source code will correctly translate to
JavaScript (You must have the source code to even start down this road).
Even if it did, you probably won't have any of the supporting libraries on
the client side.
Instead, you use GWT's RPC mechanism to call routines on your

supporting HTTP. So your PHP app should provide a (maybe RESTful) interface,

The code for accessing the database is running on the server-side of
the RPC[servlet].
Moreover, if mysql-jdbc-driver cant use these inetaddress class, then
we cannot access the database even @ server side? is there anyother
way or my configuration is wrong?

If you are using Google App Engine, you cannot access databases even @
server side. You are tied to the persistence approach that GAE provides.

I am writing a fairly large web app using GWT in Eclipse.My background

stumble on easy stuff.
Anyway, I am currently attempting to implement a database to store data from
my webapp. I am far from an expert in SQL,
I dont have any tutorials at hand but your understanding of where the
DB code lies is correct. It's totally on the server side and has
nothing to do with GWT. Your GWT app would get access to the data via
RPC. The RPC methods would in turn get data from the DB.

I've used hibernate extensively and have had serious issues with it. The

I much prefer IBATIS, where the SQL is plainly visible and editable, and you
still get simple POJO manipulation. IBATOR can generate most of the

From GWT compilation, junit coverage, packaging ... very easily once
you've made the effort .
But I agree that it's quite complex.

Imho, maven is overdesigned if you don't have junit tests and other
stuff. Ant is more than enough for just creating a war file(i do it
with one button-click in eclipse). The only manual step is to copy it
to your webapps-folder on the server ;-)

For automating the deployment (instead of manually copying) ant is the
only way to go. I've heard stories that Maven is even easier, but we
haven't jumped onto that band wagon (yet). When we build with no
server, we have an ant build file that does all that, and then deploys

Yes you create it yourself and place your server code, specifically
the RPC service, under that folder. You cannot put any server code
into the Client folder because it will try to compile it into
javascript for the browser.
