Hi!
I created a very simple test application with the Eclipse PlugIn from
a freshly installed GWT 1.6.4. When trying to connect to the database,
I get a java.lang.ExceptionInInitializerError calling getConnection:
public ServiceImplementation()
{
try
{
Class.forName("com.mysql.jdbc.Driver");
} catch (Exception e)
{
e.printStackTrace();
System.exit(1);
}
try
{
connection =
DriverManager.getConnection("jdbc:mysql://localhost/
testdatabase", "root", "pwd");
} catch (SQLException e)
{
e.printStackTrace();
System.exit(1);
}
}
I am able to connect to the database using the MySQL Query Browser.
Also, the same server code worked with previous GWT versions. I use
Ubuntu 8.10, Eclipse 3.4.2.
Any help is appreciated!
Thanks,
Martin.
The server is running at http://localhost:8080/
