adding a context-param programmatically?

Question

Is there a way to add a context-param programmatically? I don't want to add in the web-xml. Specifically I want to do what the answer in this post suggests: Invoking methods with parameters by EL in JSF 1.2.

Answer 1

Yes it is possible.

In the servlet's init method, use

getServletConfig().getServletContext().setInitParameter("[Parameter name]", "[value]");

OR simply

getServletContext().setInitParameter("[Parameter name]", "[value]");

This must do the trick for you.

For the application load,

In web.xml, when you declare this servlet, provide <load-on-startpup> element as 1 for this servlet.

<servlet>
 <servlet-name>TestServlet</servlet-name>
 <servlet-class>TestServlet</servlet-class>
 <load-on-startup>1</load-on-startup>
</servlet>
