I am not sure there is any central place where this is documented (except for maybe in the EJB/Servlet/other specs). Theres some data on it at http://jakarta.apache.org/tomcat/tomcat-4.0-doc/jndi-resources-howto.html But basically it comes down to the following. Each application/bean/whatever can declare that it needs other sresources via something like <resources-ref> <description>...</description> <res-ref-name>myKey</res-ref-name> <res-ref-type>java.lang.Integer</res-ref-type> <res-auth>Container</res-auth> </resources-ref> Translated into avalon terms this would say that the is an entry in the context under key "myKey" that is of type "java.lang.Integer". Avalon has no notion of authenticating (thus no need for res-auth) because we have no need. > and the > converter stuff Just look in jakarta-avalon-excalibur/converter Basically it contains a bunch of converters that convert strings into types (like Integers, Longs etc). And there is a master converter that you use like final Converter c = ...get master converter...; final Integer i = (Integer)c.convert( Integer.class, "53", null ); So basically you convert to a destination type (Integer.class) from a source object ("53") in a specific context (null). > >>Before answering the above, I'll go into a more detail concerning Merlin > >>configuration semantics. > > > >...snip... > > There you go again ... snipping the best bits of my emails! > > :-) :) -- Cheers, Peter Donald -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
