The pljava-examples subproject builds the supplied examples; this
machine-generated page is a project summary for developers of PL/Java.
If you arrived here from a search for PL/Java examples, you probably want the Examples section of the user guide, or maybe to browse the example sources, or even read their javadocs. (Note: the source browser link shows the current development sources, which may differ from a particular release.)
The optional example code for providing actual XML Query-based
alternatives to PostgreSQL's XPath 1.0-based query and XMLTABLE functions
does not get built by default, because it pulls in the sizeable Saxon-HE
library from Saxonica, and because (unlike the rest of PL/Java) it requires
Java 8.
To include these optional functions when building the examples, be sure to use
a Java 8 build environment, and add -Psaxon-examples to the mvn command
line. The functions are documented here.
