Appendix D: The Java-Based XQL Processor

This chapter describes how you use XQL to select raw data from Adaptive Server, using the XQL language, and display the results as an XML document.

XML Services provides a Java-based XQL processor. The Java-based XQL processor implements the XQL language, which is an extension of XPath.The Java-based XQL processor is a preliminary implementation of XPath-based XML query facilities. Its capabilities are superseded by those of the native XML processor.You can either install the Java-based XQL processor in the server, or run it outside the server. Running it outside the server is like running any Java program on the command line.This appendix first addresses running the Java-based XQL processor as a standalone program, outside the Adaptive Server, and then addresses running it inside the Adaptive Server.
