Java consists of a class-based program.

Sometimes you need to find out where the class loads.

This can be found in the following ways: Use the jsp file.

If there is a class in the jar file, the jar file is displayed as well.

<%
java.net.URL clazz = null;
clazz = this.getClass().getResource("/org/springframework/scheduling/quartz/JobDetailFactoryBean.class");
out.println( (clazz == null ? "null" : clazz.getFile()) + "<br/>" );
%>
