java.util.zip.ZipException: error in opening zip file

[HARI OM]

I am using SuSE Linux 9.0, JDK 1.4.2, JBoss 4.2.

I have simple hello.java file and created hello.class filw without any
problems. I also set my CLASSPATH to point to SERVLET.JAR file. and
then put this HELLO.CLASS file under jboss/server/default/deploy
directory on which I get following ERROR... wonder why: I am trying to
run this Hello World Servlet from browser as:
http://localhost:8080/hello

Here is the ERROR I get on JBOSS COnsole when I start JBoss:
