Agreed with C=C3=A9dric, as JSR-223 is really too brained-= down to be really useful.

It's still however possibl= e to cast the Groovy javax script engine to its concrete implementation cla= ss, and then you can access the underlying GroovyClassLoader used, and set = the CompilerConfiguration to what you want.
But you're now ti= ed to the specifics of the Groovy implementation of JSR-233.

I received the question:

org.codehaus.groovy implementation of Groovy (groovy-all) provides a mechanism to set imports when evaluating Groovy code via CompilerConfiguration and ImportCustomizer. I don't see the equivalent in javax.script in ScriptEngine/S= criptContext. Is there a way I can add (implicit) imports in javax.script, perhaps by setting a ScriptContext attribute?

Can anyone throw any light on this?=C2=A0 MrHaki has a nice article on the Groovy side.
