Groovy Processor

Hi,

I need to use a Groovy Processor but I only seem to be able to find support
for Predicates and Expressions on the docs.

Is it possible to use Groovy Processors Out-of-the-box, by referencing
external .groovy files? If so, how exactly should the process method be
implemented?

What I am after is actually the GPath XML processing using the XmlSlurper
class. It looks like a very agile way to do custom validation on an XML.

Thanks!

May be "file:groovy:/path"?
Because "groovy:<expression>" could be used for inline expression then.

Hi James,

Ok, I see.

One thing is puzzling me though. I have come across the following class in
the Camel API: org.apache.camel.builder.script.ScriptBuilder<E>, which
contains a groovy(File) method.

What is this for?

Thanks.

We've no explicit support yet for invoking a script as a processor; we
should add that.

In the meantime, if you compile your groovy on the classpath you can
just refer to the Groovy class in the bean...

  from("....").bean(SomeClass.class);

We should maybe have a script endpoint?

  from("...").to("groovy:foo/bar/Whatnot.groovy");
