Thanks Ceki,
This works for me. I tested and asyncAppender does what I wanted.
I'd like to ask you, however, if there's a way to add at the end of a
Throwable information a semicolon or something.
I have my file appender configure with PatternLayout as follow:
<layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d; [%t]; %-5p; %c;
As you can see everything is separated by a semicolon. This works for me
because I use MS Excel to open my log files.
Most of the columns are aligned except for the "exception" one. How can I
add a semicolon to the end of exception string so I can use
it as a delimiter........
Can this even be done?
