You can also use $xwiki.parseGroovyFromPage().
Here an example:

The cleanest is probably to write a script service in
Groovy, see
http://extensions.xwiki.org/xwiki/bin/view/Extension/Create+a+component+usi…
for an example.

Thanks for your response.
But how can I create o "global" binding to an instance of my class? The
background is: I would like to avoid programming rights required, and so
I believe, I need Velocity and not a bit of Groovy in the referencing
page.
In fact, I need one instance of the groovy class and references in
Velocity from several pages.
How is this possible?

Hi all,
after I managed to write a groovy class with a static method within a
groovy block:
{{groovy}}
class MyClass {
static myFunction(out) {
out.println "hello world"
}
MyClass.myFunction(out)
{{/groovy}}
I would like to invoke thos static groovy class function from within a
Velocity block:
${MyClass.myFunction(out)}
But unfortunately, this does not work. Nothing will be displayed.
Has anybody an idea for help?
Thanks Matthias
