Reading environment entry from a custom tag ..

[Ant Swa]

Hi,
I am trying to read an environment entry from a simple tag. I am using Tomcat 3.2 and the code inside the tag is as follows, where "name" is the environmnt entry name, which i have put in the web.xml file.
try{
InitialContext context=new InitialContext();
Object obj=(Object)context.lookup("java:comp/env/"+name);
pageContext.setAttribute(name,obj,PageContext.PAGE_SCOPE);
}catch(javax.naming.NamingException ne){
throw new JspException(ne.getMessage());
}
When i call the jsp page which consists of the tag, i can see from Tomcat window that environment entry is set initially. but the jsp page, simply gives the exception :
"javax.servlet.ServletException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial"
Anybody please help..

it looks like the initial context provider is not set - the initial context may not be available on your system. You may need to set the provider when you are starting you application or perhaps set the system variable in an on startup loaded servlet

... and an easy way to do this is just to put a jndi.properties file in the classpath of your web application (e.g. in WEB-INF/classes).
