centos7上的tomcat7无法解析EL表达式

userList只是起的名字，包含的是一个对象。
服务器上的tomcat日志：
Nov 07, 2017 3:10:15 PM org.apache.jasper.compiler.TldLocationsCache tldScanJar
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 JARs during scanning can improve startup time and JSP compilation time
求大神帮忙！！！
