com.opensymphony.xwork2.interceptor.ParametersInterceptor error SEVERE: Developer Notification (set struts.devMode to false to disable this message):
Unexpected Exception caught setting 'Screen_name' on 'class org.ScreenCreation: Error setting expression 'Screen_name' with value ['kjn', ]
I'm new with struts2 and I have this error, can any one help me to solve it ?
Unexpected Exception caught setting 'Screen_name' on 'class org.ScreenCreation: Error setting expression 'Screen_name' with value ['kjn', ]
That error means you are missing the Setter for your attribute in the Action.
if the attribute is Screen_name, the setter should be
public void setScreen_name(){}
but that's a really wrong syntax for a variable, try avoiding underscores and especially capitalized first letter by usign camelCase, eg screenName:
private String screeName;
public void setScreenName(){...}
