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

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

问题来源：

使用了CKEditor和CKFinder后，在lib里添加了很多jar包，打开相应页面出现以上问题。

org.apache.jasper.compiler.TldLocationsCache tldScanJar
信息: 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.

（1）有人说是的问题，可是我的页面里根本就没有。

（2）还有说，修改${TOMCAT_HOME}/bin/catalina.sh或${TOMCAT_HOME}/bin/catalina.bat文件，可是tomcat目录下没有这两个文件。

（3）还有说，调整${tomcat}/conf/catalina.properties，将提示的jar添加到不扫描清单中。没有试，而是通过下面的方法解决了。

最终解决：

修改$CATALINA_BASE/conf/catalina.properties文件，添加org.apache.el.parser.SKIP_IDENTIFIER_CHECK=true选项。
