OK everyone, I will do my best to describe my problem but bear with me. I am using struts tokens to stop double submit of a jsp page.

// Before the page first loads this statement runs in a different Action:

// Next in the actions execute method the code goes like follows:
String result = StringConstants.SUCCESS;
if (isTokenValid(request))
Properties prop = new Properties();
String selected = prop.getSelected();
String navigation = prop.getNavigation();
if (selected.equals(StringConstants.NEXT)){
result = executeNext(mapping,request, prop);
else if (selected.equals(StringConstants.PREVIOUS)){
result = executePrevious(mapping,request);
else if (selected.equals(StringConstants.FINALIZE)){
result = executeFinalize(mapping,request, prop);
// Now I do some catch statements which have been omitted
// next I reset the token and return the result
return mapping.findForward(result);

findForward will forward me back to the same page when executeNext or executePrevious is called. When the first request comes in it checks to see if the token is valid. It is valid, so it starts processing (executeNext for example). While the first request is processing, the second request comes in. The token is not valid (as it has been reset), so it skips everything that modifies the state of the application, goes to the end, executes saveToken and returns success (exactly what we want it to do!!!). Next the first request finishes processing and returns success but by then the jsp page has already reloaded by the second request. The jsp page doesnt reload and nothing happens. This is bad.

I need either a) the first request to return first or b) the second request to return something that wont reload the jsp page. Here is an exerpt from my struts-config:

<action path="/configure"
scope="request" unknown="false">
<forward name="success" path="Tiles.ConfigurationPage" />
<forward name="finalize" path="Tiles.QuotePage" />
<forward name="failure" path="/WEB-INF/jsp/badLoginForm.jsp" />

I sure hope you understand :-). Please help.
