Adding servlet in Sites

MahalwarJul 10 2014 — edited Oct 29 2014

Hi All,

I tried implementing my custom jar and changed the web.xml file to include servlet mapping then my application server (managed server) status went to Failed from Active. I placed my jar in lib folder and created a page in sites on which on click of a button I redirect the request to servlet.

I guess I cannot directly change web.xml of sites and resatrt the application server to include my servlet. can anyone tell me where else I need to make entry of my servlet as following is the error I got in log or Is something I am doing wrong to include my servlet in Sites:

please help

----------------------------------------

code that i wrote on click of button (simple one button on on page)

<satellite:form action="/WECSPDF" method="post" name="WecsForm" >
<input type="submit" value="submit me"/>
</satellite:form>
<p> Sites team hellooo</p>

---------------------

MY entry in web.xml

....

</servlet>

<servlet-name>WECSPDF</servlet-name>

<servlet-class>com.cms.wecs.pdfrreader</servlet-class>

</servlet>

<servlet-mapping>

</servlet-mapping>

<servlet-mapping>

<servlet-name>WECSPDF</servlet-name>

<url-pattern>/WECSPDF</url-pattern>

</servlet-mapping>

<mime-mapping>

__________________

My servlet code:

package com.cms.wecs;

import javax.servlet.http.*;

import javax.servlet.*;

import java.io.*;

class pdfrreader extends HttpServlet{

public void doGet(HttpServletRequest req,HttpServletResponse res)

throws ServletException,IOException

{

res.setContentType("text/html");//setting the content type

PrintWriter pw=res.getWriter();//get the stream to write the data

//writing html in the stream

pw.println("<html><body>");

pw.println("Welcome to servlet");

pw.println("</body></html>");

pw.close();//closing the stream

}

--------------------------------------------

Error that I got when i restarted my server after changing web.xml:
