Next you need to have server side class something like this:
-----
package com.company.server.gwt;
public class TeacherServiceImpl extends RemoteServiceServlet
implements TeacherService
{
private static final long serialVersionUID = 1L;
public List<PupilDTO> getPupils(Integer teacherId)
{
List<PupilDTO> results = performYourServerSideAction();
return results;
}
}
---
Then in your GWT.xml file you need to link the server to the client
with servlet mappings like so:
<servlet path="/teachers"
class="com.company.server.gwt.TeacherServiceImpl"/>
Notice I use /teachers to map to my server side class.
Thats pretty much it. Your DB code that you have already shown us
should go on the server side either in your ServiceImpl class or
another server side bean (preferred)
