INFO: 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

原因：根本原因是Jar包检查TLD标签没有通过，是因为jsp页面包含<!-- -->注释，去掉就好，是tomcat7才有，tomcat6没有，后来找了一半天还是不行，就换成了tomcat6，然后就可以了
