It depends on what is generating the stack trace. In order to get this behavior there has to be a line by line emission of the stack trace using System.err.println() for each line rather than one System.err.println() with the entire stack trace as a message. What is the source of this?
You are right: I use e.printStackTrace(), and here is the code from Throwable.java:
public void printStackTrace(PrintStream s) {
synchronized (s) {
s.println(this);
StackTraceElement[] trace = getOurStackTrace();
for (int i=0; i < trace.length; i++)
s.println("\tat " + trace[i]); Throwable ourCause = getCause();
if (ourCause != null)
ourCause.printStackTraceAsCause(s, trace);
}println for class name and message, println for every entry.
Any ideas how to cut the corner here? Vlad

Subject: Re: [JBoss-user] log4j SMTP appender trouble
It looks like the logging event contains just 1 line from the exception trace instead of the whole trace!!! Is this a bug or a feature?
Vlad
Hi all, I activated SMTP appender to send errors by e-mail, but can't properly
configure it. Every time an Exception happens, I receive a lot of e-mails with every e-mail body containing only 1 line of the Exception
trace log, like:
[16:49:04,315,STDERR] at com.sybase.jdbc2.jdbc.SybStatement.queryLoop(SybStatement.java:1596)
Here is config:
<appender name="SMTP" class="org.apache.log4j.net.SMTPAppender"> <errorHandler
class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
<param name="Threshold" value="ERROR"/>
<param name="To" value="..."/>
<param name="From" value="..."/>
<param name="Subject" value="${jboss.server.name} JBoss Error"/>
<param name="SMTPHost" value="..."/>
<param name="BufferSize" value="100"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{ABSOLUTE},%c{1}] %m\r\n"/>
</layout>
</appender>
What's wrong? How to configure it to e-mail the whole trace at once?
Thanks, Vlad
