Java.lang.RuntimeException:Invalid Action class configuration references an unknown class Nam

It may be that your configuration does not have this class or you do not have a corresponding operation on the returned parameters.
I was using struts2.1 once is the return string is not configured all have this problem

Just can't find the class you want to use, are you sure that your class is called studentaction? Is it wrong to write, the general class of the first letter is capitalized, such as Studentaction. Java is case sensitive

Ava.lang.RuntimeException:Invalid Action class configuration references an unknown class named error

This question was hit by me today, so lucky!!!

Online search, summed up the most is the configuration file or the field is wrong to write the reason. But I found my no config file, just a rewrite validate method

The whole process is verification, my main problem is: Login sometimes success, sometimes fail. Report java.lang.RuntimeException Error!

Also prompt for ClassNotFound error, think of struts2 configuration, default to Sington mode, if you are not configured in spring. That you want to log in at the same time multiple users will appear this exception, the spring scope to change the prototype property.
