Subject flow of code
Date Thu, 22 Apr 2004 20:16:40 GMT
Hi,

I am newbie to WSRP.  I need a little help understanding what is going on
in the code once we start up the SwingConsumer.  What is the flow of code
after that?!  Which files should I "follow" so that I can understand the
interactions going on between the SwingConsumer and the wsrp-webapps (the
one in Tomcat) producer?! Is there any documentation about this
somewhere?!  This will allow me to experiment with creating and modifying
portlets.

Thanks very much for your support,
Regards,
Anuraag
