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?

It's not really relayed to Groovy, Velocity
cannot work with statics.
You will have to work with non static methods and assign one script
binding to an instance of your groovy class like in:
{{groovy}}
class MyClass {
myFunction(out) {
out.println "hello world"
}
mytool = new MyClass()
{{/groovy}}
{{velocity}}
$mytool.myFunctionnction(out)
{{/velocity}}

http://lists.xwiki.org/mailman/listinfo/users 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
