Enable Debug logging for this logger to a complete list of JARs that were scanned but no TLDs we Re found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

The problem is that your page contains <!----> notes removed, tomcat7.0.20.

Tomcat 7 has strict syntax requirements for El expressions, such as "${owner.new}" which causes parsing errors due to the inclusion of the keyword new.
The problem is out, how to solve it. There are three kinds, as follows:
The first: Strictly follow the Java specification, modify the object's property name, the requirement does not include Java keywords;
The second: modifying El expressions, such as "${owner.new}", can be modified to "${owner[' new"} ";
Third: Modify the Tomcat attribute, ignoring the keyword check for El expressions. Modify the $catalina_base/conf/catalina.properties file and add the Org.apache.el.parser.skip_identifier_check=true option.
