I want to use JDOM in my GXT project. Adding only the library in the ClassPath and importing the classes I need in my GXT java files doesn´t work. I´ve read it´s necessary to inherit the module on the gwt.xml config file, but I don´t know exactly what I should write there.
I´ve tried with <inherit name='org.jdom'> but it doesn´t work.
You cannot simple use any class. You need to create a module file for it etc. Than you need to hope that it only uses classes which can be used on the clientside. This question is more GWT related than GXT.
