      SUBJECT: java.lang.NoClassDefFoundError
      I am using Tomcat 4.1.31 on SuSE Linux 8.1 and Java 1.4

      I have my application as following:

      /local/tomcat/webapps/hari
      /local/tomcat/webapps/hari/index.html
      /local/tomcat/webapps/hari/WEB-INF/classes/util/BatchUpload1.class
      /local/tomcat/webapps/hari/WEB-INF/classes/util/*.class
      /local/tomcat/webapps/hari/WEB-INF/lib/cos.jar (this is Oreilly's predefined classes)
      /local/tomcat/webapps/hari/WEB-INF/web.xml

      I access my WEB application as http://us.hari.com/uhin/BatchUpload and get following error wonder why:
      --------------------------------------------------------------------------------
      description: The server encountered an internal error () that prevented it from fulfilling this request.

      exception

      I am using Oreilly's predefined classes which are stored in "cos.jar" file and under WEB-INF/lib/ directory... I have also added this to the CLASSPATH...


      When I un-jar my cos.jar file I get follwing files...
      com/oreilly/servlet/*.classes


      Any pointer on this would be appreciated...

      THANKS!
