hi,
I am writing a helloworld sample for sca groovy service, but encountered
a problem here:

I gave an investigation on this issue, What I found is,
GroovyClassLoader's parent class loader is Null (pls see in
GroovyComponentBuilder.java) , in addition, the parent classloader for
GroovyClassLoader is obtained from DeploymentContext, actually this
DeploymentContext will always be constructed without specify a classloader.
(pls see line 90 in DeployerImpl.java).
Does anybody can tell me that this problem is caused by usage error or
product issue?
