Date: Fri, 10 Oct 2003 12:18:03 -0700 To: Tomcat Users List <[EMAIL PROTECTED]> From: Justin Ruthenbeck <[EMAIL PROTECTED]> Subject: 4.1.27: Manager app 'reload' causing ClassNotFoundException
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:
2003-10-10 12:05:06 HTMLManager: restart: Reloading web application at '/news'

CalculatorServlet.class exists only under the directory: $TOMCAT_HOME/webapps/news/WEB-INF/classes/com/nextengine/news/servlet
The only modifications made to the default installation is the appropriate additions to tomcat-users.xml. No changes were made to server.xml. Since thousands of people use this, I'm assuming there's something simple going on here. Restarting the Tomcat process results in all resources being available once again.
Hoping another pair of eyes can see what's wrong...
Thanks, justin
