[Mapserver-users] Error compiling java mapscript classes (Mapserver 4.0)

[GeoIT]

Dear list,

While making java mapscript module I receive the following errors:

              ^
3 errors
make: *** [mapscript_java] Fehler 1

Which occurence of the methods setExtension and setMimetype in class
outputFormatObj should I remove ?
The return Type in mapObj.clone() should be set to Object instead of mapObj.
Is it OK to do the chanches in the java source files ? I think they should
preferably done in the interface file, but I don't know how. Please advise !
 
My System configuration: 
Mapserver 4.0
swig 1.3.19
Sun JDK 1.4.1_01
