Dont get it: Logging
Hi,
need a hint.
Struts is using the commons Logging.
private Log log =
LogFactory.getLog("org.apache.struts.webapp.Example");
1)
Where actually can I find the log file??
It should be where it is configured in the package org.apache.commons.logging
configured in commons-logging.properties
But there is no propertie-file.
2)
if (log.isDebugEnabled()) {
log.debug(" User is not logged on in session "
+ session.getId());
}
Why is that? log.debug("something") would do? Is it for speeding up??
thanks, Rainer
validator example needed
Posted by Javier Muguruza <jm...@lapize.com>.
Hi,
We are using validator, version 20010702, we cannot use a newer version
cause ServletExect3.1, the server we use, has a bug that prevents it from
using commons-logging, and newer versions of the validator rely on this.
Struts version is 1.02.
We think we have everything set up ok, but cannot make the validation work,
is there an example somewhere that we could use as template (preferabily
with an old version of the validator like the one we are using)
thanks,

The "commons-logging.properties" has to be visible to the web app class
loader. The easiest way is to put it in "WEB-INF/classes".

RE: Dont get it: Logging

Does the commons logging fall under the same configuration options as
log4j? If so, where would I place this properties file? (I'm assuming
web-inf/classes)

See the commons-logging javadocs for more info:
http://jakarta.apache.org/commons/logging/api/
Basically, commons-logging defaults are based on:
* If Log4J is visible, use it
* If running on JDK 1.4, use it
* Default to a "no-op" log that swallows all messages.

Yes. If you just did:
log.debug(" User is not logged on in session " + session.getId());
without the if statement, the String concatenation would be performed
even
though the message was going to get thrown away. With lots of
log.debug()
calls, this can really add up.

without the if statement, the String concatenation would be performed even
