Tomcat7解决“At least one JAR was scanned for TLDs yet contained no TLDs”问题

问题：org.apache.jasper.servlet.TldScanner.scanJars At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.**解决方案！！！

解决方法：

找到/usr/local/tomcat/bin下面的catalina.sh找到如下行加入一行：

在Tomcat的bin目录下找到catalina.sh，然后打开它，在以下位置添加一行代码-Djava.security.egd=file:/dev/urandom

再重启即可生效果然，这个警告不再出现，速度也快了。
