if you're using JDK 1.1.4, then there's a bug which prevents
this from working on Win95/NT machines.
the bug will be fixed in the next release.
the workaround:

in a temporary subdirectory:
1) jar xvf signedWriteFile.jar
2) jar cvf newSignedWriteFile.jar META-INF\DUKESIG.SF META-INF\DUKESIG.DSA
writeFile.class writeFile.html
3) use this new signed jar file in place of the old signed jar.
thanks for pointing this out, and sorry for the inconvenience.
