Subject RE: Passing parameters to a bean from a JSP
Date Tue, 04 Apr 2000 12:19:23 GMT
I am am still having this same problem.  I believe it's a connection issue
between Apache and Tomcat, but I can't figure out what it is.  If I hit
Tomcat directly, the Post parameters make it through, but not when they come
through Apache.  

K.C.
