Chapter 12. Working with Java and XQuery

Qexo: An XQuery-to-Java Compiler
Both Qexo and XQEngine, discussed later, are implemented using Java, but you don't have to know Java to use them.

(However, check the respective licenses, especially if you're thinking of using open-source code as part of a commercial application.)
Qexo is written in Java, and it compiles XQuery expressions and programs to Java bytecodes (
.class files). Qexo is available from http://www.gnu.org/software/qexo/ ...
