public class JRubyScriptFactory
ScriptFactory implementation
for a JRuby script.
Typically used in combination with a
ScriptFactoryPostProcessor;
see the latter's javadoc for a configuration example.

public JRubyScriptFactory(String scriptSourceLocator,
Class[] scriptInterfaces)
scriptSourceLocator - a locator that points to the source of the script.
Interpreted by the post-processor that actually creates the script.scriptInterfaces - the Java interfaces that the scripted object
is supposed to implement| Method Detail |

public void setBeanClassLoader(ClassLoader classLoader)
BeanClassLoaderAwareclass loader to
a bean instance.
Invoked after the population of normal bean properties but
before an initialization callback such as
InitializingBean's
InitializingBean.afterPropertiesSet()
method or a custom init-method.
setBeanClassLoader in interface BeanClassLoaderAwareclassLoader - the owning class loader; may be null in
which case a default ClassLoader must be used, for example
the ClassLoader obtained via
ClassUtils.getDefaultClassLoader()public String getScriptSourceLocator()
ScriptFactoryTypical supported locators are Spring resource locations (such as "file:C:/myScript.bsh" or "classpath:myPackage/myScript.bsh") and inline scripts ("inline:myScriptText...").

ScriptFactoryCan return null if the script itself determines
its Java interfaces (such as in the case of Groovy).
