Thanks, that helped! The key was to use "declare namespace java...." instead of "import module namespace java....".

The subtle difference was lost on my first reading of the documentation, but I now see and understand the example on the Java_Bindings page thanks to your reply.

Much appreciated!

In your case, i think, java:TITLE() would work.

Just trying with java.lang.Integer i got the following code to work

declare namespace integer="java:java.lang.Integer";

integer:MIN_VALUE()

For example, if the Java class is declared as

package my.module;

public class MyModule { public static final String TITLE ="I'm a module!";

public String hello(final String world) { return "Hello " + world; } }

The XQuery to call the "hello" method is

import module namespace java = 'java:my.module.MyModule';

java:hello("World!")

But is there any way to access "TITLE"?

I'd like to share some constants between XQuery and Java, and I could write accessor functions for these constants, but it'd be cleaner if I didn't have to.

Thanks!
