Java classpath used by Spring

问题

I know a way to print the classpath of a project at runtime like here:

http://www.mkyong.com/java/how-to-print-out-the-current-project-classpath/

But sometimes the main is even too late, for example when using spring.

Is there a way to print something(e.g. classpath) even before Spring starts the injection process?

Providing some context, i am running a unit test in spring as follows:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:/jmsAppContext.xml")
public class TestProjectProvisioningIntegration
{
....

}

It finds correctly the jmsAppContext.xml, but fails to find one of the properties files.

To get the same effect as you have in the link you posted, you could get the classpath in a static initializer (just do the same as the example, only then in a static { ... } block instead of a main method. The JVM will execute the static initializer first, before loading any other classes your class depends on (other than the classes you reference in the static initializer).
