Is there any proxy server(SSL capable) written in Java?

[frankpeng]

I was thought Tomcat can be set up as a proxy server like Apache. But actually 
not. Right?
I have Tomcat installed. How nice to have another instance running as a proxy 
server?
 
If I cannot do this, I would rather find a nother proxy server instead of 
Apache because I like everything in JAVA.
 
Thanks !
