Accessing servlets in Websphere

Question

I have written a simple test servlet and deployed it on websphere applications.

When i try to access the servlet it gives me following error

Error 404: SRVE0190E:

I have checked all the basic things like web.xml entry, servlet syntax etc.

Everything is correct.. The same servlet when deployed on Tomcat is working fine.

I also checked the

com.ibm.ws.webcontainer.invokefilterscompatibility property in Servers > Server > Web Container Settings > Web Container > Custom Properties .. it is set to true.

Not getting exactly what is the issue. If any one could help to resolve this issue

The serlvet that i created :

  public class TestServlet extends HttpServlet{

private static final long serialVersionUID = 1L;

public TestServlet() {      
        super();
     }

public void init(ServletConfig config) throws ServletException {
    super.init(config);
}


protected void doGet(HttpServletRequest request, HttpServletResponse response)  
 throws ServletException, IOException {
    PrintWriter out = response.getWriter();     
    out.print("This is a testing servlet ... Please ignore");
}

protected void doPost(HttpServletRequest request, HttpServletResponse response)  
 throws ServletException, IOException {
    doGet(request,response);            
}

}

Entry in web.xml :

 <servlet>
      <servlet-name>TestServlet</servlet-name>              
      <servlet-class>com.wizard.servlet.TestServlet</servlet-class>
 </servlet>
 <servlet-mapping>
       <servlet-name>TestServlet</servlet-name>
       <url-pattern>/TestServlet</url-pattern>
 </servlet-mapping> 

The war file which contains the servlet is deployed on one of the cells in Websphere server. Thanks in advance.
