Adding Java packages to GWT

Question

I\'ve tried searching but couldn\'t come up with a defined way on how to add your own packages to a GWT project.

My tree structure looks like this:

-com.         


        

Answer 1

You can get rid of the two source path lines, because by default GWT will pick up anything that is relative to the root, and in the client package like you have. You also need to move your gui package into your client package, so it would become:

-com.mycompany
  -public
    MyApplication.html
  MyApplication.gwt.xml


-com.mycompany.client
  MyApp.java

-com.mycompany.client.gui
  TableLayout.java



  
  

Assuming your MyApp.java is an actual EntryPoint, then this should work just fine.

One other thing to note is that you cannot use java classes that are not part of the GWT JRE Emulation library, and your project won't compile if you do. You should get very specific errors about this though. For example you cannot use library classes like java.math.BigDecimal, if they are not emulated. All of your own classes you create can be used though.
