I am not quite sure where your problem comes from but the usual way of making a JAR from your source code is the following:

javac -d tmpclasses-folder -bootclasspath \path\to\WTK20\lib\midpapi.zip -classpath tmpclasses-folder file1.java file2.java ...
[I](javac is the normal compiler from JDK 1.4)[/I]
\path\to\WTK20\bin\preverify -d output-folder -classpath \path\to\midpapi.zip tmpclasses-folder
jar cfm YourJar.jar MANIFEST.MF -C output-folder .
[I](jar is the normal jar tool from JDK 1.4)[/I]
jar uf YourJar.jar -C res-folder .
[I](to include ressource files)[/I]

tmpclasses-folder and output-folder are used to place compiled classes and verified classes into. Take care to include the midpapi-archive so that both the compiler and the preverifier know what you want to do.
