Hi,

I'v run into something quite puzzling (at least to me taht is ;-) ).

The following code gives me a ClassNotFoundException when i try to load Foo via
its own classloader.

ClassLoader cl = Foo.class.getClassLoader();
cl.loadClass("Foo")

Classloaders have never been my strong point but this is really beyond me.
Why is it throwing this exception?? What am i doing wrong\ not understanding?

tia,

Hi!

Perhaps you should specifie the fully qualified name of Foo.class. Say
Foo.class is in package app, then try cl.loadClass("app.Foo") and invoke
java by specifying the path to the package app. So if app is located in
/home, then java -classpath /home home.app.Foo

Sorry, i forgot to mention that including the whole path.to.the.class indeed
does work. But i thought that using it without the path also worked or shouldn't it?

I don't know. Perhaps by adding the path of Foo.class to the JVM's class
path, but i don't know, how to do this.
