java.lang.ClassNotFoundException: com.apnabox.presentation.servlets.SystemFilter.class


[I am not sure] just check filter-class mapping name . is it end with *.class* string? if yes remove and give an another try.

checkout your code..

did you implement filter class with your filter with proper imports of javax dorectories..
and your filter class is placed in web-inf/class/* directory of your web-app ..

This is not correct. The correct directory is WEB-INF/classes

This error simply means that the com.apnabox.presentation.servlets.SystemFilter class has not been included in the web application. What is this class, and where did you place the class file?
 
It is sorta covered in the JavaRanch Style Guide.
