>
>
>Hello All:
>
>Tomcat 4.1.27
>JDK 1.4.1_02
>OS: Windows 2k
>
>I've thoroughly read:
>http://jakarta.apache.org/tomcat/tomcat-4.1-doc/manager-howto.html
>http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.html
>This list for the past 16 months :)

>Problem: My (simple demonstration) webapp runs fine if Tomcat is started
>from scratch. If I use the Manager app from either the html or ant
>interfaces, executing the 'reload' command completes without error, yet
>all servlets are unavailable afterwards. Hitting a servlet results in the
>following being logged:
