question on context-param

[rick collette]

hi, guys:
The params defined between <context-param></context-param> are accessible by all servlets. I am wondering how I am able to put
params accessible by all servlets and paran accessible by ony one specific servlet together
in deployment descriptor? Could anyone give an
example? Thanks.

Rick,
The DD would look like this.
<web-app>
<context-param>
<param-name> TheParam </param-name>
<param-value> ParamValue </param-value>
</context-param>
<servlet>
<servlet-name> MyServlet </servlet-name>
<servlet-class> ServletOne </servlet-class>
<init-param>
<param-name> MyServletParam </param-name>
<param-value> ValueForMyServlet </param-value>
</init-param>
</servlet>
Regards,
Clark

Rick,
Be sure to close </web-app> in above example.
Sorry,

That's correct. Here is another example:
The <context-param> element will provide the ability to make parameters global to a specific web application. While the sub-elemnent <init-param> of the <servlet> element will provide the apility to make parameters available to an individual servlet.

  
<web-app>
   <context-param>
      <param-name>globalParameter</param-name>
      <param-value>1</param-value>
   </context-param>
   <servlet>
      <servlet-name>SomeName</servlet>
      <servlet-class>com.SomeName</servlet-class>
      <init-param>
         <param-name>firstParam</param-name>
         <param-value>2</param-value>
      </init-param>
      <init-param>
         <param-name>secondParam</param-name>
         <param-value>3<param-value>
      </init-param>
   </servlet>
    .....
</web-app>
