). As an auxiliary debugging tool, if the specified class cannot be found in the current classpath, the program obtains the java. class. path System attribute and displays the current classpath (24-28 rows ). It is easy to imagine how the above simple code works in a Java Servlet using the Servlet engine classpath or in an EJB component using the EJB server clas
