I think you are right, but I always use Thread method because it works even in a static method - you do not need 'this' for it to work. I prefer having one way to do this instead of two - that way I can think less about how to get the CL, and more about the problem it will help me solve (and I am lazy). ;-) Larry >>> [EMAIL PROTECTED] 06/05/03 10:58 AM >>> >"Are you using this code to get a classloader? >Thread.currentThread().getContextClassLoader(); >If not, you are not getting tomcat's you are getting the system one." Are you sure this is true? A ClassLoader can have a parent ClassLoader. But, a class does not maintain a single copy across all ClassLoader contexts. Therefore, the Class type can exist in multiple ClassLoaders. So a Class has a reference to it's ClassLoader context when it is created. When the this.getClass().getClassLoader() is called it calls the context that the class was loaded in. I think you would have to specifically call the getParent() of the Classloader in order to go up the Classloader chain. In this situation I think Thread.currentThread().getContextClassLoader() and this.getClass().getClassLoader() will accomplish the same thing.

Are the static variables transient? If not, the session manager may persist them on a reload. >>> [EMAIL PROTECTED] 06/05/03 9:41 AM >>> I have tried it both ways. My notion is that it has to do with the fact that the getResourceAsStream is being called in a static method and the resulting InputStream, which is wrapped in an InputStreamReader, is passed into an object that is a static variable in my BaseDAO class. So, because the reference is at the Class level it might be holding onto it no matter what I do. If you want I can show you the code. I have some ideas. But, I'm not sure if they will work.

Hey Brandon, Are you using this code to get a classloader? Thread.currentThread().getContextClassLoader(); If not, you are not getting tomcat's you are getting the system one. Larry >>> [EMAIL PROTECTED] 06/05/03 8:04 AM >>> Yes, it is closed.
