Pagination

[Kunal Lakhani]

I am working on a Servlet-hibernate application. I have a list of 20 records. I have displayed the whole 20 records in a page, but, I need to implement pagination in such a way that 5 records are displayed in a page, & it has only next button to move to another 5 records. For this i am using JSP taglib for paging. But I am facing some problem.

Here is my code :

Web.xml

<?xml version="1.0" encoding="UTF-8"?>

	<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" >
	
	
	<servlet>
	<servlet-name>Start</servlet-name>
	<servlet-class>org.nit.Servlet.DisplayServlet</servlet-class>
	</servlet>
	
	<servlet-mapping>
	<servlet-name>Start</servlet-name>
	<url-pattern>/start</url-pattern>
	</servlet-mapping>
	
	<taglib> //This gives the error.
    <taglib-uri>
      http://jsptags.com/tags/navigation/pager
    </taglib-uri>
    <taglib-location>
      /WEB-INF/pager-taglib.tld
    </taglib-location>
  </taglib>
	
  <welcome-file-list>
    <welcome-file>HomePage.html</welcome-file>
  </welcome-file-list>
</web-app>

This is my jsp page. (Displays the whole 20 records)
Test.jsp

<form action="./checking" method="post">
 
 <c:forEach var="testing" items="${Record}" varStatus="Qno">
 <br/>
 Data : ${Qno.count }) <br/>
  ${testing.question} id:${testing.id }
  <br/>
    <input type="radio" name="r${Qno.count}" value="${testing.optn1}">${testing.optn1}<br/>
   
    <br/><br/>
    </c:forEach>
   <input type="submit" value="Submit">
   </form>

Here is modified Test.jsp

<form action="./checking" method="post">
 <pg:pager maxIndexPages="10"
 maxPageItems="5"
export="pagerPageNumber=pageNumber" >
 <pg:item>
 <c:forEach var="testing" items="${Records}" varStatus="Qno">
 <br/>
 Data : ${Qno.count }) <br/>
  ${testing.question} id:${testing.id }
  <br/>
    <input type="radio" name="r${Qno.count}" value="${testing.optn1}">${testing.optn1}<br/>
   
    <br/><br/>
    </c:forEach>
   <input type="submit" value="Submit">
   </pg:item>
   
<pg:index>
 
 <pg:prev>
 <a href="<%=pageUrl%>"> PREVIOUS </a>
 </pg:prev>
 
<pg:next>
<a href="<%=pageUrl%>"> NEXT</a>
 </pg:next>
 
</pg:index>
</pg:pager>
   </form>

I cannot even run this application, as the web.xml shows an error

Any paging strategy purely in hibernate?

[Bear Bibeault]

There is no need to put the taglib declaration in the deployment descriptor.

[Kunal Lakhani]

Removed Taglib declaration from the deployment descriptor. Its still displaying all 20 records in a page.

Should i go for Display tag library?

[Tim Moores]

Using DisplayTag would be the standard approach for doing pagination in JSPs IMO.

[Kunal Lakhani]

Let me tell you the actual requirement.

Its a kind of online Test application, where 5Questions are displayed in a jsp page with a NEXT button. If user clicks Next button. another set of 5Questions is displayed. I have already retrieved 25 Questions in a List. I am using hibernate as the persistent tool.

Using DisplayTag would be the standard approach for doing pagination in JSPs IMO.

What is JSPs IMO? How should i proceed?

[Tim Moores]

IMO

[Kunal Lakhani]

Didn't get you

Then let me rephrase my previous post with the abbreviation expanded:

Using DisplayTag would be the standard approach for doing pagination in JSPs in my opinion.
