Hello:
We are using Groovy in the web application and some classes loaded via
Groovy script get serialized and added into HttpSession object. In
clustered environment when other Tomcat server try to deserialize we get
ClassNotFoundException.
I tried something like below code in a simple Java.
ScriptEngineManager factory = new
ScriptEngineManager(Serialization.class.getClassLoader());
ScriptEngine engine = factory.getEngineByName("Groovy");
String groovyScript =
IOUtils.toString(Serialization.class.getResourceAsStream("/blah.groovy"),
Charset.defaultCharset());
Class<?> myClass = (Class<?>) engine.eval(groovyScript); // this line loads
org.venkat.Blah class
GroovyObject myObj = (GroovyObject) myClass.newInstance();
Serialization.class.getClassLoader().loadClass("org.venkat.Blah"); // this like
shows class not found exception
Is there any way to load Groovy script classes into parent classloader?
you do not need a parent, you need the right child. Children of
ClassLaoders are always supposed to ask their parents first, before
serving a loadClass call themselves.
So I assume that:
myClass.getClassLoader().laodClass("org.venkat.Blah")
would work.
Is that right?
