<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Hi there, im trying to setup loggers programatically and noticed that logback / log4j wont create the empty directory for you using rollingfileappender. Here is what ive had to do to get the parent directory recursively created because i wont be sure what the parent directory of the logger will be until its created. Is there a better way ?<DIV><BR class="khtml-block-placeholder"></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" face="Monaco" size="3"><SPAN class="Apple-style-span" style="font-size: 11px;"><SPAN class="Apple-tab-span" style="white-space:pre"> </SPAN>LoggerContext lc = (LoggerContext) </SPAN></FONT><FONT class="Apple-style-span" color="#0000C0" face="Monaco" size="3"><SPAN class="Apple-style-span" style="font-size: 11px;">logStats</SPAN></FONT><FONT class="Apple-style-span" face="Monaco" size="3"><SPAN class="Apple-style-span" style="font-size: 11px;">.getLoggerContext();</SPAN></FONT></DIV><DIV style="margin-top: 0px;
