How to debug in JSP Page

Posted on by

To find the Variables assigned in JSP page use Windows->Show View->Display

  • In debug perspective: Window -> Show View -> Display
  • Put a break point in your code

Lets have a expression like one below

 <c:if test="${user.isSuccess}">
 .
 . 
 </c:if>

Now i need to find the value of user.isSuccess you can run the below code in in Display to see the values
set in the userObject

_jspx_page_context.findAttribute("user")

It takes the value from the Page context and displays the values stored in the User Object

Note : The pageContext, _jspx_page_context are different variable names used for based on IDE while debugging JSP page.
