b)The content that need to be in server jar file are
jar cvf HellowWorldDemoEJB.jar ejb\demo\* META-INF\

D:\jboss-4.0.4.GA\server\default\deploy
d)The jar files that need to be in classpath while compiling client files
javac -classpath
D:\project7\HellowWorldDemoEJB.jar;D:\jboss-4.0.4.GA\client\jboss-j2ee.jar

7) -Djava.security.policy=java.policy is must to pass as the argument.
Java,policy file which will be under
