Tomcat 7 has strict syntax requirements on El expressions. For example, "$ {owner. New}" May cause parsing errors because it contains the new keyword.
The problem arises. How can this problem be solved? There are three types:
First, strictly abide by the Java specifications. Modify the attribute name of an object without containing the Java keyword;
Type 2: Modify the El expression. For example, "$ {owner. New}" can be changed to "$ {owner ['new']}".
Third: Modify Tomcat properties and ignore keyword checks on El expressions. Modify the $ catalina_base/CONF/Catalina. properties file and add the org. Apache. El. parser. skip_identifier_check = true option.
