Recommended Upgrades for log4j-1.2.14

2010-10-08 Thread Vsanam 
Hi All,

I am currently using log4j version of log4j-1.2.14 and I am finding answer for 
the below questions and I couldn't get proper answers from the site 
http://logging.apache.org. So anyone could help me out to find out the answers 
for me or atleast tell me where I can get information for below questions:

1.  What are the new versions of log4j?
2.  Any recommendations to upgrade from log4j version 1.2.14.
3.  What are the new Challenges that log4j-1.2.14 is facing currently?
4.  Any architect relevant articles for latest versions of log4j
5.  Ensure the log4j-1.2.14 is still relevant and is not becoming obsolete  
by another or competing tool 
6.  What are the critical security patch that are needed for log4j-1.2.14?
7.  What are the critical security patch in some other software that
requires this log4j-1.2.14 to be upgraded?
8.  What are important new features that would improve development  
significantly?
9.  Whether current version(log4j-1.2.14) is more than 2-3 years old or 
has became out-of-date?


 

Sincerely,

Re: locating my log4j.properties file

2010-10-08 Thread Jacob Kjome 
It's great that you got it working, but it doesn't appear you fully understand 
why...

configure(String) [1] takes a java.io.File path.  Given that you have provided a
relative path, rather than a fully qualified one, location of the file is going 
to
be relative to the directory from which you started your JVM.  In your case, it
happens to be the same directory in which your Jar file exists.  But you can't
depend on this because your JVM may be started from another directory and this
relative location may become invalid.  And you generally want to avoid the File
system anyway in your Java programs to keep them from being coupled to a
particular environment setup.  For these reasons, I suggest that you use a URL 
[2]
instead and load your config file from the classpath, e.g.,

URL url =
getClass().getClassLoader().getResource(com/mypackage/log4j-config-file.properties);
PropertyConfigurator.configure(url);


But lets step back for a second.  Unless you are doing something special as far 
as
loading the config file, there's no reason you can't rename your config file to
log4j.properties.  This will get picked up automatically without you having to
manually configure Log4j.  Just place it in the root package on your classpath 
and
it will get picked up (unless log4j.xml also exists, in which case it will be 
used
in preference to log4j.properties).

The other option, which also avoids manual, programmatic, configuration is to 
set
the property log4j.configuration, e.g.,

Example of a URL on Windows...
-Dlog4j.configuration=file:/C:/some/path/to/my/log4j-config-file.properties

Example of a URL on UNIX...
-Dlog4j.configuration=file:/some/path/to/my/log4j-config-file.properties

 Thanks, with the -Dlog4j.debug, I was able to figure out that log4j was 
 looking for a default log4j.xml file which I do not have, but I then copied 
 the a11yMonitor-log4j.properties into the same folder as my test 
 application's jar file  and that worked.  Getting log4j output now!

 Hello
 
 start your programm with:

 This will show you information were it looks for your properties file.
 It usually helps me in this case

 PropertyConfigurator.configure(a11yMonitor-log4j.properties);

 Where do I actually place the a11yMonitor-log4j.properties file?

 I tried in jdk_home\jre\lib and jdk_home\jre\lib\ext but both times I tried

 Any help would be greatly appreciated.

RE: locating my log4j.properties file

Jake,

I will take all this into account in my final production setup.

For now I was using the log4j as a debugging tool for myself, so just wanted to 
figure out how it works.

RE: locating my log4j.properties file

2010-10-08 Thread Don Raikes 
Hello again,

Ok so I solved some of my issues, but now I have others.

In my log4j.properties file, I have configured 3 appenders.
A1  console apppender
A2  file appender to my errors.log file
A3  file appender to my fulltrace log file (see below)

When I run the test program using -Dlog4j.debug, I can see that all the 
appenders are being created no problem.

However, nothing is being written to either of my file appenders a2 or a3 even 
though my console appender (a1) is receiving all the output).

Any suggestions on how I have misconfigured things would be appreciated.
