Configuring JSP init parameters

[Abhishek Jain]

Hi All

I am screwed with a problem where I wana to read init-param from jsp

JSP LOCATION :-
/webapps/JSPCounter/JSPCounter.jsp

Web.xml Contents :-
<servlet>
<servlet-name>JSPCounter</servlet-name>
<jsp-file>/JSPCounter.jsp</jsp-file>
<init-param>
<param-name>myID</param-name>
<param-value>[e-mail]</param-value>
</init-param>
</servlet>

Overriden init method :-

public void jspInit(){
ServletConfig scg=getServletConfig();
String myID=scg.getInitParameter("myID");
System.out.println(myID);
ServletContext scx=getServletContext();
scx.setAttribute("myID",myID);
}

when i am using this code its giving me null value ???

You can try to define the servlet mapping for this servlet. In your case, you can define the mapping as follows:

 
<servlet-mapping>
<servlet-name>JSPCounter</servlet-name>
<url-pattern>/JSPCounter.jsp</url-pattern>
</servlet-mapping>

Hopefully it works.

Hi Abhishek,
Your code is perfectly legal. No error in your code. I think there is some configuration problem. Check your web.xml file for servlet configuration and servlet mapping. If you would change in your web.xml just restart the server and try it in browser. Hope it will helps you. If you have same problem again give me your web.xml file.

Hi Abishek,
Could you please verify the web.xml is available in webapps/JspCounter/WEB-INF/web.xml.
