String pkgName = lc.getModuleName();
String append = LOG4J_APPEND_KEY_PREFIX + pkgName;
initData(fw, LOG4J_KEY_PREFIX + pkgName, lc.getLogLevel() + COMMA

initData(fw, append + FILE_KEY_PREFIX,
"${logdir}" + lc.getLogFileName());

initData(fw, append + ".Append", "true");
initData(fw, append + MAX_FILE_SIZE_KEY_PREFIX, lc.getLogFileSize()
+ "MB");
initData(fw, append + MAX_BACKUP_INDEX,
String.valueOf(lc.getLogMaxFileCount()));
initData(fw, append + LAYOUT_KEY_PREFIX, LAYOUT_VALUE);
initData(fw, append + LAYOUT_PATTERN_KEY, LAYOUT_PATTERN_VALUE);
