Hi Guys -
I know this is a little off topic, but the groovy mailing list doesn't seem
to be very active, and I need to track down an answer on this. What I'm
trying to do is call a groovy script from a java class (an Action) and pass
over the current Http Request object. Here's the calling Java code :
<snip>
GroovyClassLoader groovyClassLoader = new
GroovyClassLoader(classLoader);
Class groovyClass =
groovyClassLoader.parseClass(form.getValidationScript());
GroovyObject groovyObject = (GroovyObject)
groovyClass.newInstance();
Object[] args = {_request};
validated = ((Boolean) groovyObject.invokeMethod("run",
args)).booleanValue();
</snip>
And here's the (very basic) groovy script :
<snip>
import javax.servlet.http.HttpServletRequest;
public class Validate {
public Boolean run(HttpServletRequest request) {
println("queryString is " +
request.getQueryString());
return new Boolean(true);
}
}
</snip>
When I run this I'm getting the following error :
java.lang.NoClassDefFoundError:

For some reason groovy is looking for the CoyoteRequestFacade, not the
normal javax.servlet.http.HttpServletRequest. So, for all of you groovy
guru's out there, how can I do this?
Thanks!
