RE: How do I use filters in AND condition fashion?
Eric, There are some filter classes in the log4j-sandbox cvs that you might want to look at. http://cvs.apache.org/viewcvs/jakarta-log4j-sandbox/src/java/org/apache/log4 j/filter/ MatchFilterBase.java is the base class for most of them and it allows configuration for OR and AND type filter chains. It can get a bit confusing though. Please take a look at and let me know if you can make heads or tails of it. If you have suggestions for making it clearer, or a better design, I'd like to know. thanks, -Mark -Original Message- From: Eric Gravel [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 19, 2003 8:50 AM To: [EMAIL PROTECTED] Subject: How do I use filters in AND condition fashion? I've been looking at the sample code given in Ceki's Log4J book, chapter 6, and it seems that if I had a filter chain such as the one below that it is a OR condition type statement. If there's a match on the first filter it accepts the message and stops processing there. If it doesn't match on the first one, it goes to the second filter and if there's a match there it stop as well. What I'd like to do is filter message on a condition such as all messages of level INFO and containing the text test for example. Is this possible with the current distribution of log4j? filter class=org.apache.log4j.varia.LevelMatchFilter param name=LevelToMatch value=INFO / param name=AcceptOnMatch value=true / /filter filter class=org.apache.log4j.varia.StringMatchFilter param name=StringToMatch value=test / param name=AcceptOnMatch value=true / /filter Eric A.

RE: How do I use filters in AND condition fashion?
I'm not sure about whether this capability is available using the latest distribution's set of filters, but I've contributed a simple expression language and an ExpressionFilter (should be a part of the next release) which provide support for expressions using a number of operators, grouping (parens), AND, OR and NOT operators, etc.. You will be able to define an expression like: ( LEVEL == INFO ) ( MSG == TEST ) Hope this helps, Scott -Original Message- From: Eric Gravel [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 19, 2003 8:50 AM To: [EMAIL PROTECTED] Subject: How do I use filters in AND condition fashion?

Yes...currently in the varia package, although I understand Mark may be planning a move to a new package for the filters. By the way, since the expressionfilter relies on the rules we've been working on, the rules should probably move out from under the chainsaw package. -Original Message- From: Paul Smith [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 19, 2003 2:14 PM To: Log4J Users List Subject: RE: How do I use filters in AND condition fashion?

Bizarre, I was doing a search from within Eclipse, and I could not find it in the source, I must be going loopy.

Yes, a good candidate for their own package under org.apache.log4j thanks. Paul - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
