Hi all,
I apologize for being completely off-topic (this question has nothing to do
with Tomcat), but I thought there may be some guys here that are experts in
class loading and are able to answer my question.
You probably know the method java.lang.Class.forName(String name) which returns
a class object from the given name. The JavaDoc (Java 7) of this method says:
Returns the Class object associated with the class or interface with the
given string name. Invoking this method is equivalent to:
Class.forName(className, true, currentLoader)
where currentLoader denotes the defining class loader of the current
class.
While this description may be a bit ambiguous about what "current class" means
here, the JavaDoc of Class.forName(String name, boolean initialize, ClassLoader
loader) makes it clearer by stating:
For example, in an instance method the expression:
Class.forName("Foo")
is equivalent to:
Class.forName("Foo", true, this.getClass().getClassLoader())
So, shouldn't this mean that I get the same result/behavior when writing this
code:
public void doSomething() throws ClassNotFoundException {
Class<?> clazz = Class.forName("foo.Bar");
// do something...
}
Instead of this one:
public void doSomething() throws ClassNotFoundException {
Class<?> clazz = Class.forName("foo.Bar", true,
this.getClass().getClassLoader());
// do something...
}
or did I misunderstand something?
Thanks!
Regards,
Konstantin Preißer
