OS: OSX 10.2.8
Eclipse: 3.0M4 Build id: 200310101454
Fresh install for MyEclipse (no other plugins installed)
MyEclipse: 3.6.3
java version “1.4.1_01”
Using same version of java to launch Tomcat 4.1.2x

I was wondering if you could help me understand how the console works when debugging a webapp on Tomcat.

If I start tomcat from outside of eclipse / MyEclipse, I have all of my app’s log information sent to “myapplication.log” using log4j….When I start tomcat to debug using eclipse /Myeclipse, however, I only see the results of what would normally be catalina.out. My “myapplication.log” file never gets written to, nor can I see the output of my log.debug(“some log stuff”) statements in the eclipse console…..Do you know how I can get access to “myapplication.log” from eclipse when using MyEclipse to start tomcat??

Thanks

When you launch TC from commandline what additional information are you providing to enable log4j logging? By default everything TC echos to stdout/stderr will be displayed in the MyEclipse console view. So my guess is there is log4j configuration information that needs to be included on the Tomcat connector’s JVM preferences. Let us know what you find out.

When I launch TC from commandline I don’t pass any additional information…But I do have a log4j.properties file in my WEB-INF/classes dir that contains logging preferences (see below). I’m using Log4J implementation via the jakarta commons logging Log interface……This gives me the capability to do things like automatically email myself if error conditions occur….but like I said, when I start TC from the command line (no special arguments) using $CATALINA_HOME/bin/startup.sh my application writes a log file called hris.log, but when I start it with MyEclipse, hris.log never get added to, nor do I see the logging output in the console in the IDE….

Contents of log4j.properties:

# The root logging configuration
log4j.rootCategory=ERROR, mail, rolling

# Custom package log levels. For now, I want extra logging output for
# my own classes and related tools.
log4j.logger.tahc.hris=DEBUG
log4j.logger.net.sf.hibernate=ERROR
log4j.logger.org.apache.commons=ERROR
log4j.logger.org.apache.struts=ERROR

# Logging configuration for stdout (will go to catalina.out on tomcat)
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%p] %d{DATE} %c – %m%n

# Logging configuration for the hris.log file
log4j.appender.rolling=org.apache.log4j.RollingFileAppender
log4j.appender.rolling.File=hris.log

Nathan,

So, did you put your log4j.properties file under the root of your project’s source folder so it will be added to WEB-INF/classes for you? When you deploy the application is your log4j.properties file deployed where it should be?

Ooops…disregard this thread — I figured out my problem. The first line in my log4j.properties file didn’t have “stdout” after rolling…..should have looked like this:
log4j.rootCategory=ERROR, mail, rolling, stdout

Thanks,
nate
