You can use any Java compiler to compile Java classes. To define a new compiler the IDE can use, choose Project | Settings from the main window.

Right-click the Compiler Types node and choose New | CompilationServiceCategory Service from the contextual menu. A subnode for the new compiler type appears under Compiler Types. You can then configure the new compiler type on its property sheet.

You can set the new compiler type for a class by opening the class's property sheet, clicking the Execution tab, and setting the Compile property to the new compiler type.

Similarly, you can configure debugger types and execution types using the Debugger Types and Execution Types nodes in the Project Settings window.
