It's hard to debug what the problem is since you didn't say what the error
is, but if it didn't exist before adding the given code then it might be
that you've got a bug in how you're setting up your logging and the error
messages from Log4j are therefore trying to write out to STDERR, which
causes infinate recursion.
To see if that's the problem, try doing this instead (assuming you're
running Log4j 1.1.1):
public static void setErrOut()
throws IOException
{
org.apache.log4j.helpers.LogLog.setQuietMode(true);
PrintStream prt = new PrintStream(
new LoggingOutputStream(
Category.getRoot(),
Priority.INFO), true);
System.setOut(prt);
System.setErr(prt);
}
If that stops the infinate recursion (which I'm guessing is the problem, but
I don't know since you never said) then you have a problem in how you're
setting up your appenders. Don't call setErrOut(), start up your
application with "-Dlog4j.configDebug=true" and it should tell you what the
problem is.
(I remember there was discussion about being able to change where LogLog
sends its messages -- and I thought I read that it had been done -- but I
can't find any code in LogLog that allows that.)

Hi Jim,
I have seen and tried your code from contrib but I could not get it
running. Here I attach the method I call but the application gets blocks
for a long time and then I get an exception
In the e-mail I read the discussion about such issues, but I did not
understand the discussion.
public static void setErrOut()
throws IOException
{
PrintStream prt = new PrintStream(
new LoggingOutputStream(
Category.getRoot(),
Priority.INFO), true);
System.setOut(prt);
System.setErr(prt);
}
