When I run multiple threads I get lost in System.out.println output because I suppose each thread has to be in a different consoles.

Is there an easy way to manage it using Eclipse?

EDIT: The problem is not to know which message belongs to each thread. The exact problem is that the console stops printing when a new thread is called, and the same happens with log4j too.

    I just configured to write all my log in a file.

    <appender name="rolling-file" class="org.apache.log4j.RollingFileAppender">
        <param name="file" value="home/.../mylog.log" />
        <param name="MaxFileSize" value="1000KB" />
<!--        Keep one backup file -->
        <param name="MaxBackupIndex" value="4" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d [%t] %-5p %l - %m%n" />
        </layout>
</appender>
