I have managed to install Cocoon 2.04 -vm 14 running on Tomcat 4.1.24 (Win 2K). Yet, I am unable to complete a request to http://localhost:8080/cocoon
Initially, I got the following exception when I tried (see note [1] below for stack trace):
org.apache.avalon.framework.configuration.ConfigurationException: Error in sitemap configuration : UnnamedSelector: ComponentSelector could not find the component for hint []
Which seems to have something to do with the generated sitemap_xmap.java file's 'configure' method.
I then tried to simplify things by using a minimal sitemap, as indicated in the development documentation
(http://cocoon.apache.org/2.0/developing/httprequest.html). See note [2] below for a copy of this.
Now, having deleted tomcat's 'work' directory when I again tried to make a request, I got the following different exception (see note [3] below for stack trace):
org.apache.avalon.framework.configuration.ConfigurationException: Error in sitemap configuration : org.apache.cocoon.transformation.XalanTransformer
Please note: I had already moved new xaml, Xerces and Xalan jars into Tomcat's 'endorsed' directory during install.
So, consequently, I am left puzzling over two different errors, one relating to the what Cocoon thinks is a missing component from its own default sitemap, and another Xalan based one, even though I was using a documented sitemap and had replaced the relevant XML jars.
I am completely stumped!
Please, can anyone help here?
Thankyou
Jon
