Classpath in java and spring

I am majorly confused about where the classpath is. I understand when we create a spring mvc, resources folder, or inside web-inf is considered classpath. And we can use "classpath:" inside xml files to declare the folder. However, where is this classpath exactly? How is it set ? I have been reading about it for a long time, i still couldnt manage to get a real clear image in my head how the classpath is initially determined etc.

For example when we create a war file, and deploy it on a tomcat server, all the resource files can still be read via given paths with "classpath:" in the xml files. How does this work?

Thanks.

The Classpath is where the JVM will look for class files and other resources. Since you are using Spring MVC, I assume you are deploying a Web application (ie WAR file). This means that the classpath is set by the container which is following the Servlet spec.

The classpath for a WAR file includes the WEB-INF/classes and WEB-INF/lib folders. The Java EE/Servlet container where the WAR file is deployed will also include other common folders in the classpath.

Here is how Tomcat works.

Ok, if it's web application, the classpath begins in WEB-INF/classes. Also, jar files in WEB-INF/lib are also on the classpath.
