In my opinion, XPath is much too weak of a query language for relational databases. What you want is something like XQuery, which is a superset of XPath that includes relational semantics a la SQL.
I wonder if there is an open source project similar to JXPath, but with XQuery as the base language. I looked at the SourceForge project called JXQuery. Very interesting, but it does not appear to have ambitions beyond XML applications. Did I misunderstand? Mapping of XPath semantics to Java objects is a highly contraversial issue - when I was building JXPath I had to make many decisions on that front that I myself was not very comfortable with. I can only imagine the magnitude of this problem if we try to map XQuery to arbitrary object models. Can anybody see an easy solution there? - Dmitri ----- Original Message ----- From: "Brian McCallister" <[EMAIL PROTECTED]> To: "Jakarta Commons Users List" <[EMAIL PROTECTED]> Sent: Friday, January 02, 2004 11:15 PM Subject: Re: [JXPath] Plans for JNDI, JMX and Filesystems? > I don't know about these, but I am trying to talk any of the JXPathers > into helping put together the ability to query persistent object models > via OJB (which will mean building OJB queries from JXPath AST's or > something)... > > -Brian > > On Jan 2, 2004, at 3:49 PM, Michael Nascimento Santos wrote: > > > Hey, > > > > I just would like to know if there are any plans for JXPath to provide > > special support for navigating JNDI, JMX and filesystems. > > > > Thanks, > > Michael > > > > --------------------------------------------------------------------- > > To unsubscribe, e-mail: [EMAIL PROTECTED] > > For additional commands, e-mail: [EMAIL PROTECTED] > > > > > > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
