Hello,

I've a very basic question regarding java classpath.
Here's how my app directory structure looks like
C:\apps\java\com\bos\order\persistence and my property file order.properties is stored under com directory. All my java classes lie under persistence directory with the package structure com.bos.order.persistence.
In my java class when I execute the following stmt I do not get the url of the location where the order.properties is stored.
URL url = this.getClass().getClassLoader().getResource("order.properties");
But if I specify
URL url = this.getClass().getClassLoader().getResource("/com/order.properties");
I'm getting the value.
My classpath looks like this C:\apps\java;
My question here is, in order for java to successfully get the resources other than .class files (like .properties and .xml) do I've to specify their location in my classpath?.
Thanks
Maalti Iyer

Yep.
It looks for the exact file you specify, in that exact context. Therefore "/my.properties" matches the first my.properties file found on the ClassPath, and "/com/my.properties" matches the first my.properties file found in the "com" sub-context on the ClassPath. Otherwise "my.properties" could accidentally be matched by "/some/other/location/my.properties" by accident and you'd have a good chance of returning the wrong file without realising.
