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(AdaptiveClassLoader.java:450)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java) at Some.doGet(Some.java:320)

ectionThread.run(SimpleTcpEndpoint.java:338) at java.lang.Thread.run(Thread.java)

(Sorry for sending an unwrapped line which is normally not my habit :-)

Some.java 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:

"/usr/local/build/tomcat/classes:.:/usr/local/build/tomcat/lib/ant.ja
r:/usr/local/build/tomcat/lib/classes111.zip:/usr/local/build/tomcat/lib/classes

al/jdk1.1.8/lib/i18n.jar:/usr/local/jdk1.1.8/lib/classes.zip"

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