XQuery Engine

XQuery API For Java

The XQuery API for Java (XQJ), currently under development under the Java Community Process as JSR 225, lets programmers use XQuery for XML programming and data integration, with full access to the J2SE and J2EE platforms. XQJ allows a Java program to connect to XML data sources, prepare and issue XQueries, and process the results as XML. This functionality is similar to that of JDBC Java API for SQL, but the query language for XQJ is XQuery.

DataDirect XQuery® implements XQJ, which allows developers to dramatically simplify Java programs that work with XML and relational data. It supports Early Draft Review 1 of JSR 225.
