I suppose that you can't hit "Fame" (whatever that might be) directly? Or that you are afraid of the load that hitting "Fame" directly would put on the system? I don't really see why dumping the data into Oracle or whatever is any different from creating an intermediate XML file? They are both data stores... You need to determine what the functional requirements are in terms of performance and querying and let that determine the technical architecture and not just pick operating system managed XML files arbitrarily. However, either way Cocoon still may be a good fit; it can handle output from an relational database (with JDBC) almost as easily as handling an XML file directly and if you have to create the XML from scratch it probably makes more sense to do that with Cocoon instead of using some other external tool to do the job. --------------------------------------------------------------------- Please check that your question has not already been answered in the FAQ before posting. <http://xml.apache.org/cocoon/faq/index.html> To unsubscribe, e-mail: <[EMAIL PROTECTED]> For additional commands, e-mail: <[EMAIL PROTECTED]>
