compile error upgrading from log4j v1.2 alpha 7 to v1.2 beta 2
I have upgrade my log4j.jar to use the v1.2 beta 2 version now.
I now get several compilation errors:
setLevel(org.apache.log4j.Level) in org.apache.log4j.Category cannot be applied
to (org.apache.log4j.Priority)
[javac] myLogger.setLevel(Level.FATAL);
myLogger is of type Logger.
Interestingly, there is no problem when using Level.OFF or Level.ALL (they are
defined in the Level class).
I thought this was my own build error, so i cleaned my classes and rebuilt.
Same thing.
I repeated with the v1.2 alpha 7 jar, and no problem. I repeat, and no problem.
I repeat using the beta 2 jar, and the compile error appears again.
I haven't looked at the source code between alpha 7 and beta 2 yet.
The javadocs do allow the method call though for setLevel(Level) which is
inherited from Category.
Any tips?
Regards,
T Master

FYI: http://jakarta.apache.org/log4j/docs/TROUBLESHOOT.html online does not
appear to have been updated.
Thanks for the casting tip. :o)

T Master,
Subsequent to your query, I added the following entry into the
Troubleshooting guide:
===================================================================
Compilation errors when using setLevel(org.apache.log4j.Level) from
the Category class.
===================================================================
If you are getting complaints such as the following from the compiler,
do not worry there is an easy solution. But first here is the problem
reported by the compiler:
[javac] setLevel(org.apache.log4j.Level) in org.apache.log4j.Category
cannot be applied to (org.apache.log4j.Priority)
[javac] logger.setLevel(Level.DEBUG);
where logger is a variable of type Logger.
Casting any of the Level.DEBUG, Level.INFO, Level.WARN, Level.ERROR,
Level.FATAL arguments to Level will make the compiler happy. As in
logger.setLevel((Level) Level.DEBUG);
This cast is always safe because log4j 1.2 will never produce anything
but Level objects, never Priority objects.
