Subject how can I debug this? ClassNotFOund Exception
Date Tue, 08 Oct 2002 14:12:56 GMT

Something has changed with bei apache tomcat installation. I installed some
php4 WebFOrum software and in the course of this I upgraded apache to 1.3.27.

The tomcat examples are working again but I still get this in my application:

Internal Servlet Error:
java.lang.ClassNotFoundException: java.util.Arrays at org.apache.tomcat.loader.AdaptiveClassLoader.loadClass(
at java.lang.ClassLoader.loadClassInternal( at Some.doGet(
at Some.doPost( at javax.servlet.http.HttpServlet.service(
at javax.servlet.http.HttpServlet.service( at org.apache.tomcat.core.ServletWrapper.handleRequest(

(Sorry for sending an unwrapped line which is normally not my habit :-) is my Servlet and I'm just doing a s=fp.list() on a 

       String s[];
       File fp = new File(SomeDir);
       s=fp.list();  <<<< offending line

I have no idea what happened. Maybe some new java got installed? Classpath is this:


I admit, it's noit a beautiful classpath but it grew that way by
during the course of time.
