How to use Data source in *.jsp

[Barry Jia]

Hi, All
I read the struts document, I config my data source in struts-config.xml, 
In my action I can use the following code to get Data source and use it.
Right now I want to use it in my JSP scriplet, when I use it, it can not be
compiled as servlet is a undefined variable or class.
I want to know, in my Action, servlet is in which package ? how to use same
code in *.jsp file
Thanks!

    DataSource dataSource = (DataSource)
      servlet.getServletContext().getAttribute(Action.DATA_SOURCE_KEY);
    conn = dataSource.getConnection();
    ... perform required functions as in the previous example ...
    conn.close();
