Apache log4j 1.2.17 Released

Yesterday, the Apache Logging team announced the availability of version 1.2.17 of log4j, which is the first new update of log4j in a little over two years. First released in May of 2002 (Happy 10 Year Anniversary?), log4j is a popular java logging library used by many applications and application servers over the years.

Labeled as a maintenance release, the changelog lists 8 fixes and downloads are available from the Apache Logging Services log4j download page. Please note that as of the time of this post, the link to the changelog on the log4j page doesn't work—use my link above.

New HOWTO Article on Configuring Access Logging in Tomcat

I promoted some of the earlier posts on this blog about configuring Tomcat Access Logging to a new HOWTO.  Also incorporated into the HOWTO is some additional information on using the new RemoteIP Valve, which allows you to log client IP or the X-Forwarded-For IP, depending on whether an X-Forwarded-For IP is received.

Check it out and let me know what you think.  Thanks!

WebSEAL: Enabling Trace Logging

There are going to be times when you will need to enable trace logging in WebSEAL in order to troubleshoot some kind of issue.  To enable, you will need to locate the routing file (typically located in the same directory as your webseald instance configuration file) and uncomment the entry that looks something like this:

 #*:*.9:TEXTFILE.10.1000:/path/to/webseald/message/logs/trace__%ld.trace.log:644:ivmgr:ivmgr

Restart the webseald process that you're looking to collect data on but be forewarned, it creates an awful lot of files!
