Tomcat5Upgrade

This is version 24. It is not the current version, and thus it cannot be edited.
[Back to current version]   [Restore this version]

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

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.

Tomcat 5.0.4 (July 15, 2003)

Tomcat 5.0.4 Alpha was released today, and according to Dave it's a useable release. Unfortunately, I cannot get it to work out-of-the-box with AppFuse. I'm getting the my favorite error:

java.sql.SQLException: Cannot load JDBC driver class 'null'

Update 1: I found that adding log4j.jar to $CATALINA_HOME/common/lib solved my problem, but now I get the following error when I start Tomcat and there is no logging to catalina.out:

log4j:WARN No appenders could be found for logger (org.apache.catalina.startup.Embedded).
log4j:WARN Please initialize the log4j system properly.

Solved no logging by adding my generated log4.properties file to $CATALINA_HOME/common/classes

Update 2: I had to put appfuse.xml in $CATALINA_HOME/conf/Catalina/localhost. So I guess the context.xml file must go in $CATALINA_HOME/conf/Catalina/localhost, rather than $CATALINA_HOME/webapps. Doh! Now I have to figure out a way to modify my "setup-tomcat" task to detect and deploy appropriately for Tomcat 5. Here is the relevant part:

<echo level="info">Copying ${webapp.name}.xml to ${tomcat.home}/webapps</echo>
<copy tofile="${tomcat.home}/webapps/${webapp.name}.xml"
            file="metadata/web/tomcat-context.xml" />        

Tomcat 5.0.5 (July 28, 2003)

Tomcat 5.0.6 (August 4, 2003)

To summarize - to install AppFuse (or StrutsResume) on Tomcat 5.0.4+, perform the following steps:

• Run ant setup-tomcat, then mv $CATALINA_HOME/webapps/appfuse.xml $CATALINA_HOME/conf/Catalina/localhost/.
• cp lib/jakarta-log4j*/dist/lib/log4j*.jar $CATALINA_HOME/common/lib/.
• cp build/appfuse/WEB-INF/classes/log4j.properties $CATALINA_HOME/common/classes/.

Later: I discovered (with Remy's help) that if I removed privileged="true" from my <Context> definition - then my Log4j issues went away. I thought that parameter meant that the app used a Realm, but after reading the documentation (Set to true to allow this context to use container servlets, like the manager servlet), I realize that I'm using it incorrectly.
