compiled Jar file contains excess class files

Question

In a NetBeans Mobility Project I have attached a zip file to the Resources folder,

this zip file contains around 10 .class files.

In my mobility application I am actually using 4 classes from the zip file, however when I compile and build my project the destination jar file seems to contain all the 10 .class files from the zip file.

I had the perception that only class files that are used by the application are compiled into the final jar. What could be going wrong?

Answer 1

I think you are making a false assumption about what netbeans will do with your attached resource file. It won't automatically figure out which ones you are using and which you aren't. There may be third party tools to help, though.

Answer 2

Try using proguard on the jar to automatically remove classes not used by your midlet class.
