Jars required to get response from JSP using HttpUnit (ServletRunner/ServletUnitClient)

I encountered various exceptions when I a wrote a HttpUnit test to call a servlet which dispatches the request to another JSP. I downloaded the required jars and updated the build path, then it worked. Below are list of jars I used:

• el-api.jar
• httpunit.jar
• jasper-el.jar
• jasper-jdt.jar
• jasper.jar
• js.jar
• jsp-api.jar
• junit-4.10.jar
• nekohtml.jar
• tomcat-6.0.33-tomcat-juli.jar
• xercesImpl-2.6.2.jar

Example Servlet:

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.http.HttpServlet;

import javax.servlet.RequestDispatcher;

public class TestServlet extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response) {

RequestDispatcher rd = request.getRequestDispatcher("jsp/index2.jsp");

request.setAttribute("test","mymessage");

try{

rd.forward(request,response);

 }catch (Exception e){

  e.printStackTrace();

 }

}

}

JSP: (present in "jsp" folder)

<% out.println("Forwarded JSP output"); 

out.println(request.getAttribute("test"));

%>

Web.xml:

<web-app id="WebApp">

<servlet>
<servlet-class>TestServlet</servlet-class>
<servlet-name>WebStandard</servlet-name>
</servlet>
<servlet-mapping>
<servlet-name>WebStandard</servlet-name>
<url-pattern>/test</url-pattern>
</servlet-mapping>

</web-app>

Example test:

@Test

public void testJSP() throws IOException, SAXException{

ServletRunner runner = new ServletRunner(new File(getClass().getResource("web.xml").getFile()));

ServletUnitClient client = runner.newClient();

WebConversation wc = new WebConversation();

System.out.println(client.getResponse("http://localhost/test").getText());

}

Output of Test:

Forwarded JSP output

mymessage
