Dear Paul

Be advised I just set the log level to ALL and below log was displayed before the NPE; seems like the page is not being Authenticated to retrieve session values:

2019-04-09 13:43:58,991 DEBUG [io.undertow.request.security] (default task-2) Attempting to authenticate /book_store/BookPreview, authentication required: false

2019-04-09 13:43:58,991 DEBUG [io.undertow.request.security] (default task-2) Authentication outcome was NOT_ATTEMPTED with method io.undertow.security.impl.CachedAuthenticatedSessionMechanism at 6640b4be for /book_store/BookPreview

2019-04-09 13:43:58,991 DEBUG [io.undertow.request.security] (default task-2) Authentication result was ATTEMPTED for /book_store/BookPreview

Kindly Advice.

Best Regards

> I have two Servlets Book and BookPreview the attribute is set in Book Servlet as follow:
>  
> Book.java
> TestBean testBean=null;
> if(session.getAttribute("testBean")!=null)
>      testBean = (TestBean)session.getAttribute("testBean");
> else{
>      testBean=new TestBean();
>      session.setAttribute("testBean",testBean);
> }
> testBean.setAmount("10");
>  
> response.sendRedirect("BookPreview");
>  
>  
> The session attribute can be retrieved and the page is loaded normally and the Amount value is displayed however when submitting the form (Post Action in BookPreview.java) Null Pointer exception is generated.
>  
> BookPreview.java
>  
> TestBean testBean = (TestBean)session.getAttribute("testBean");
> String amount = testBean.getAmount; //Null pointer exception when submitting the form
>  
> <form method="Post" action="BookPreview">
>  
> </form>
>  
> TestBean.java
>  
> public class TestBean implements java.io.Serializable {

>           this.amount = amount;
>      }
> }
