RE: No Way to Put the init() Method Inside the ActionForward Execute( ... ) Method
Why can't you call the init() method from inside the execute() method (at the
beginning of it )?

Subject: No Way to Put the init() Method Inside the ActionForward Execute( ... ) Method
We cannot put a method inside another method.
When using the Struts, we start with:
public final class MyClass extends Action
{
public ActionForward execute( ActionMapping
mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response )
throws java.lang.Exception
{
...
...
}
}
I have a void init( ...) { ... } method shown below.
Of course, I cannot put this init( ... ) inside the
ActionForward Execute( ... ) { ... }
What am I supposed to do? Do I put this void init(
... ) { ... } method before the ActionForward Execute(
... ) { ... } begins?
Code:
=
String smtpServer;
public void init(ServletConfig config) throws
ServletException
{
super.init(config);
smtpServer =
config.getInitParameter("smtpServer");
}

RE: No Way to Put the init() Method Inside the ActionForward Execute( ... ) Method
Why not write an InitServlet that is set to initialize prior to the struts
ActionServlet in web.xml? This could override the init() method and provide
the services you need.
>From web.xml
init
com.xxx.xxx.servlet.InitServlet
log4jProperties
conf/log4j.properties

Then your init() method could have something like:
public void init() {
realPath = getServletContext().getRealPath("/");
initLogging();
initDataSource();
etc...
}

I would write a Struts Plug-In (very easy) and initialize the
"smtpServer" variable (and similar variables) there, making the
configured value available to the rest of the application (including
your Actions) by setting an Application scope attribute (this also
abstracts the configuration so that in the future you might configure it
in a properties file or source file instead of web.xml).
For example:
form.getServlet().getServletContext().getAttribute("smtpServer");
