[JXTA discuss] How to run JXTA shell, thanks in advance.

I have downloaded jxta-shell-2.3.1, but when I try to run it, it display some log info then halted, what shall I do?

C:\Documents and Settings\uclab1\??\04_22 submit JXTA\jxta-shell-2.3.1\shell>java -cp .;..\lib\jxta.jar;..\lib\jxtashell.jar;..\lib\log4j.jar;..\lib\jxtasecurity.jar;..\lib\cryptix-asn1.jar;..\lib\cryptix32.jar;..\lib\bcprov-jdk14.jar;..\lib\jxtaptls.jar;..\lib\org.mortbay.jetty.jar;..\lib\javax.servlet.jar net.jxta.impl.peergroup.Boot
Jxta is now taking off. Please fasten your seat belts and extinguish all smoking materials.
