Hi, I have written an Online Shopping system. But, there a bug in it. Whenever I add an item, it is getting added twice. It will be great if anybody can point where the error is.Thanks in advance.

Source code is as follows:

index.jsp


show.jsp

Cart1.jsp


Cart.java

You are adding it in show.jsp and cart1.jsp

show.jsp


cart1.jsp



why do you want to add it in show.jsp? From the name I infer it should only display the items in cart. Not try to add an item.
 
It is sorta covered in the JavaRanch Style Guide.
