Java web application web.xml parameter in POJO

Question

I have an email utility class that is used by all my web applications on the network that send employees their forgotten password (well, the class is copied to every webapp). I need to mark up an email with the appropriate subject line, contact point of contact, the name of the application, etc., which corresponds to the application that calls it.

I can pass them as parameters, but the way I do this is to include initialize.jspin my header on the login web page.

<% request.setAttribute("siteEmail", "Commitment@<domain>.com");
   request.setAttribute("siteName", "Commitment Report Database");
   request.setAttribute("sitePOCEmail", "smith@<domain>.com");
%>

These request parameters are then stored in the DTO through a similar Struts action.

public class STKRequestPasswordAction implements ControllerAction {
public STKRequestPasswordAction() {}

public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

ApplicationConfig ac = new ApplicationConfig();
ac.setAppEmail(request.getAttribute("siteEmail").toString());
ac.setAppName(request.getAttribute("siteName").toString());
ac.setPocEmail(request.getAttribute("sitePOCEmail").toString());
request.setAttribute("ac", ac);

userForm.requestPassword(LoginUser, ac);

UserForm.requestPassword method

public void requestPassword(STKUser loginUser, ApplicationConfig ac) {

checks the entered user ID asking for the password, builds a StringBuffer message, and then calls the Email Utility class.

EmailUtils.sendEMailByBadge(loginUser.getBadge(), strFrom, strReplyTo, strSubject, emailBody.toString(), strSMTP, true);

jsp web.xml, , . POJO

String strFrom = getServletContext().getInitParameter("siteEmail"); POJO . , , :

actionMap.put(null, new STKLoginSubmitAction());
actionMap.put("chkpass", new STKLoginSubmitAction());
actionMap.put("sqlReset", new STKRequestPasswordAction());
String op = request.getParameter("method");
ControllerAction action = (ControllerAction) actionMap.get(op);

ApplicationConfig ac STKRequestPasswordAction, `ac '. ?

web.xml:

<env-entry>
    <env-entry-name>myEntryName</env-entry-name>
    <env-entry-type>java.lang.String</env-entry-type>
    <env-entry-value>myEntryValue</env-entry-value>
</env-entry>

Java:

// Do once
Context env = (Context) new InitialContext().lookup("java:comp/env");

// Do for every entry
String entryValue = (String) env.lookup("myEntryName");
