Let us see how to store
user input details in the separate
bean, actually up to now we stored user input values in
Action class by writing
setters and
getter methods, but there is a chance to store in separate
bean class, will see how.
Advantage Of Taking Separate Java Bean
Is to get
re-usability, means if more than one
Action class need to use the same
properties then same properties we can use from this java bean it self with out wiring
setters and
getters in both Action classes.
Any ways files required…
- success.jsp
- error.jsp
- index.jsp
- LogingEx.java [ in java4s package ]
- MyBean.java [ in java4s package ]
- web.xml [ in web-inf ]
- struts.xml [ in web-inf/classes folder ]
