You have to go through JNI: Java Native Interface.

Have a look at calling from a .dll using Java and JNI / Making Native Windows API calls from within a Java Application .

A jar-file is nothing more than a ZIP-file containing Java-class-files. If you have a .dll it will typically contain Windows-specific method calls etc, which have no counterpart in the Java-API (especially not in the J2ME API :-), so, the unhelpful answer is: no, there is no way you can convert a .dll to a .jar that could be used in your J2ME application.

You can call code in a DLL via the Java Native Interface, but that in no way constitutes "converting to .jar".
