I attempted to upgrade my Tomcat 4.1.24-based application to Tomcat 5.0.2 this morning and found a few issues:

1. I had to put mail.jar and activation.jar into common/lib so my log4j's SMTPAppender would work. 2. I had to copy log4-*.jar into common/lib to workaround this error: 

Caused by: org.apache.commons.logging.LogConfigurationException: No 
  suitable Log constructor [Ljava.lang.Class;@1d33a6b for 
  org.apache.commons.logging.impl.Log4JLogger at  
  org.apache.commons.logging.impl.LogFactoryImpl.getLogConstructor
  (LogFactoryImpl.java:432)
3. In one of my JSP's, I have: 
<%@ page import="org.apache.struts.Globals" %>
<c:remove var="<%=Globals.ERROR_KEY%>" scope="request"/>
This works in Tomcat 4.1.x, but fails in Tomcat 5. Is this a bug in 4.1.x or 5.x? 
org.apache.jasper.JasperException: /common/messages.jsp(12,4) 
  According to TLD or attribute directive in tag file, attribute 
  var does not accept any expressions
4. None of my logging configuration in mywebapp/WEB-INF/classes/log4j.properties file is picked up. Even moving it to $CATALINA_HOME/common/lib does not seem to help.

Tomcat 5.0.3 (June 23, 2003)

Tomcat 5.0.3 came out today, so I again attempted an upgrade. But still no luck. I had to do steps 1 and 2 again to get my app to start, and also I removed the offending code in step 3. I also had to copy the commons-logging.jar from struts-rc2 to get Log4j's SMTP appender to work. However, the database drivers won't load in this release - making it even worse that 5.0.2.
