This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
What is the difference between getinitParameter() method in ServletContext and in ServletConfig ? Can we use either of this to get the value of init patrametes ?
by using context.getInitParameter() we can access context-wide initialized parameters. These parameters are defined in web.xml using <context-param> tags. These values are accessiable to all the servlets and jsps present in the context. By using config.getInitParameter() we can access the initialization parameters defined for that servlet only. These are specific to that servlet only. These are defined in web.xml like this <servlet><init-param><param-name>user</param-name><param-value>suresh</param-value></servlet>
