Chuck,
Thanks for the "Spring Cleaning" and the positive feed back! After 3 days of analyzing logging, I was feeling a little "Logged Out", so the pep definitely helps.
I made all the changes you suggested (Good eye). I think it's ready the wiki
now, unless anyone has additional modification.
I still need to go through a few more of the earlier responses to the thread.
Thanks again,
- Ole

Thanks for putting this together. I have a few comments, mostly nit-picking.
The goal of this primer is to demonstrate how to to log with
java.util.logging (JULI)
This give the impression that java.util.logging == JULI, which is a bit misleading.
Perhaps something more along the lines of "java.util.logging, as implemented by
JULI" would be more appropriate.
Now you have a logger to create logging messages from you
class CriticalComponent.
Typo: "you class" should be "your class".
If you ran this code with a deployed web application you
would see this statement
on the console or in catalina.out out like:
Drop the "out like" from the end of that sentence.
What if you wanted the output to appear in a file and on the
console? For that you need to define a 2 Handlers.
Remove the "a" prior to the "2".
Lets start with a root Logger. A root logger is a logger
whose name is "".
What's the purpose of it.
Terminate that last sentence with a question mark, not a period.
Now remember that once something gets logged by myLogger,
it's handed over to myLogger's Handlers. But what if we
never assigned any Handlers to myLogger. How would it get
it's Handler?
The first "it's" above is correct, as a contraction of "it is"; the second one is not,
since the possessive "its" does not contain an apostrophe. There are several other occurrences of
the same typo, which I won't list.
.level = OFF
Might want to also mention the other pseudo-level ALL for the serious
tree-killers.
How do I customize the location of the tomcat logging.properies file?
"logging.properies" should be "logging.properties".
Example:
-Djava.util.logging.config.file=/etc/tomcat/logging.properties
Note that this property is not set when running catalina.sh.
The reason for this is that the download provided by the
Apache Tomcat project knows where the file is already.
Not true - the script does set the property if the conf/logging.properties file
exists. See lines 182-185 of the 6.0.16 catalina.sh script. It also set
java.util.logging.manager to point to the JULI LogManager implementation.
This is a superb addition to the Tomcat documentation set; thanks again for
creating it.
