i write a simple javabean, with name Simple.java in package test, and a manifest file Simple.mf, i use jar to package them:

jar cvfm Simple.jar Simple.mf test/Simple.class

and in the Simple.mf, i write
Name: test/Simple.class
Java-Bean: True
but when i open the result Simple.jar file, the Manifest.mf doesn't contain the "Java-Bean: True", so i could not upload the jar into BDK

anyone who can help me will be appreciated.
thanks a lot.
