Given the following line of code in a servlet:
String dburl = getServletContext().getInitParameter("DBURL");

The web.xml for this web application contains the following:
<context-param>
<param-name>DBURL</param-name>
<param-value>jdbc:odbc:MySQLODBC</param-value>
</context-param>

Which of the following statements are correct?

The following was given as the solution:
The value for DBURL cannot be changed programmatically.
Where is the value being changed programmatically, or at all?

It is not being changed in the given code. It just shows how DBURL is being retrieved. The statement in the option claims that it cannot be changed programmatically, which is correct.

HTH,

What about setInitParameter(java.lang.String name, java.lang.String value) of ServletContext?

setInitParameter works only if a parameter is not set already. It cannot change a value if it is set in the DD.

Thank you for your reply. I take this exam this coming Monday so it was important for me to clarify this. Thanks.
