i use struts jar following enter image description here

Looks like your `com.action.RegisterAction` class isn't present in your web application. You only posted code for `LoginAction.java`. Where is `RegisterAction.java`? — Christopher Schultz, Aug 10 '16 at 13:32

Approach#1:

For Tomcat 8, You need to add the following line to tomcat/conf/logging.properties for the jars scanned by Tomcat to show up in the logs:

org.apache.jasper.servlet.TldScanner.level = FINE

Approache#2:

Add this line to the end of your {CATALINA-HOME}/conf/logging.properties: org.apache.jasper.level = FINEST
Shut down the server (if started).
Open console and run (in case of Windows):

%CATALINA_HOME%\bin\catalina.bat run
Enjoy logs, e.g. (again, for Windows):

{CATALINA-HOME}/logs/catalina.2015-12-28.log

This problem has nothing to do with JAR scanning. The configuration is explicit about what class is being used for that action. – Christopher Schultz Aug 10 '16 at 13:33
