Michael, Everything works perfectly fine in your jsp and bean except that the package mentioned in your bean (Beany.java) file seems incorrect: It is:
********** BEANY.JAVA package subapp; It should be: ********** BEANY.JAVA package subclass; Or else an alternative is to change the folder in which the bean is to subapp from subclass to match the package name... Also you do not need to place a web.xml in the WEB-INF folder - I mean its optional since tomcat5.X (maybe earlier - someone please correct if I am wrong).. and if web.xml is not present the defauly web.xml settings will be applied. Hope that helps, Anoop On 5/7/05, Michael Strorm <[EMAIL PROTECTED]> wrote: > > Hi, > > First off, let me apologise for the level of detail in > this message; if possible, I'd have made it shorter. > > Anyway, I'm trying to learn J2EE; Tomcat seemed like a > good choice to learn the underlying technology, rather > than a particular JSP/Servlet container's deployment > tool.
