Re: Elementary question
Could you not place the configuration file in the root of the /WEB-INF/classes/ ? Log4j will automatically find log4j.xml or log4j.properties if it is located there. Alternatively you could use the Thread.currentThread.getContextClassLoader(), this should work well inside a Webapp. cheers, Paul Smith On Mon, 2003-09-08 at 12:23, Bhamidi Krishna wrote: Hi, I am trying to configure log4j for an app. Currently, I have deployed it on Tomcat.

Re: Elementary question
Try this... String configFileName = /com/common/logger.xml; Always use forward slashes when dealing with class loader paths. These are Java packages, not system directories (even though they look similar). One other thing. Where is the class you are using to load the logger.xml file? Is it in the same package as logger.xml (actually, I just noticed it is the InitialContext class, so the answer is no, it isn't in the same package, but anyway...)? If so, then just do.. String configFileName = logger.xml; When using the getResource() method from the Class class, resources are relative to the class. Notice in the first example that I overrode this the relative path by including a preceding forward slash which makes it look for the resource starting from the root package. You can also use the ClassLoader.getResource() method and remove the preceding forward slash to do the same thing.

Hi Jake, thankou for the mail. I tried with forward slashes \, but the context does not seem to like it, I keep gettin the URL as null. Jacob Kjome [EMAIL PROTECTED] wrote: Try this...

Re: Elementary question
InitialContext is probably loaded from a parent class loader and can't see the resource in your child class loader. Why are you using InitialContext in this situation anyway? Just use the class you are performing this from. Let's call it MyClass in a static context... MyClass.class.getResource(configFileName); in an object context... this.getClass().getResource(configFileName); There is no reason this shouldn't work.
