I also fairly new to GWT. I found the following tutorial to be helpful, however, it is 4 years old so you will have to modify some code to make it work. I suggest downloading the project file and work through the tutorial. You will need to change some things such as the location of your GWT SDK. It is also specific to the use of Apache Geronimo as an application server.

The "Data Source Explorer" allows you to set up a connection to your database that will allow you to not only confirm that you can connect to it from your workstation, but also provides schema information, etc. If you want a pure JavaScript implementation of your database lookup, you will need to use the xmlhttp function. Here's a good example of its use: http://www.w3schools.com/php/php_ajax_database.asp This requires you to write some sort of code on the server side to actually execute the SQL query and return the data. I used a Perl script, but you can use any language you like. Making this work can be a challenge at first and it has a lot more overhead than using an application server and database pool (illustrated in the IBM tutorial above). -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
