RE: How configure the categories for console, logFile and htmlFile showing different levels

[David]

Dear Bender,

 

Thanks four your xml sample now it works as I expect, on the attached file you will find it.

 

Nevertheless I have some comments, I am not log4j expert, but I guess the syntax could be simplified, and probably it is possible:

 

1. With your suggestion, I have to specify explicit each external library, but the opossite would be easier to define, but I don't know how to set it, all my classes belong to the package: com.schinvest, so this package will be at INFO level for console, file, and htmlFile, any thing else will have WARNING level for all appenders. Probably this could be configurate in simpler way, but I don't know how to do it.

 

2. On cathegory node there is no way on the class attribute to specify more than one class at the same time, is that true?

 

<category name="org, net.sf">
        <level value="warn"></level>
        <appender-ref ref="file"/>
        <appender-ref ref="htmlFile"/>
</category>

 

so this cathegory will be applied for org.* and net.sf.* packages, that would simplify the log4 configuration, but I have tested it and it doesn't work.

 

Thanks for your help,

 

David

Here is an example of an xml configuration which uses filters (BTW: Using this two appenders when debugging in eclipse the console shows the DEBUG and INFO in black color and the others in red color). You can also write your own filter class where you are free to filter what you want. Be careful on the ordering when extending this xml file. The logj4 parser expects first all appenders followed by all loggers.
