Subject Error: Class <classname> not found; org.apache.tomcat.server.Http ServerConnector deprecated?
Date Thu, 27 Jul 2000 19:26:34 GMT
I found that Wrox Press has a pretty good JSP book called Professional JSP.
It uses Tomcat 3.0 in it's examples, along with JServ and the Apache web
server.  It seems that I have everything setup correctly, but when doing the
exercises, I frequently get a Class <classname> not found error when
attempting to encapsulate java code in beans/classes, and am not sure why.

I did notice, in their setup, I was to add a section in the server.xml file
that refered to a class that was apparently removed in Tomcat 3.1, but was
in 3.0 (org.apache.tomcat.server.HttpServerConnector).

<Connector className="org.apache.tomcat.server.HttpServerConnector">
</Connector>

Would this cause the problem?  Why are my beans/classes not able to be found
by my jsp's?

I have attached some sample code.  Any assistance would be greatly
appreciated.  Thank you.
