description The requested resource (/ loginAction.action) is not available.
------ Solution -------------- ------------------------------
landlord, is that you address the problem ah. .
you see your namespace is myspace then each request path can be coupled myspace
Also in js developed under the absolute path to the best path.
so the
form.action = "/ loginAction.action";
form.action = "registerAction";
changed
form.action = "$ {pageContext.request.contextPath} / myspace / loginAction.action";
form.action = "$ {pageContext.request.contextPath} / myspace / registerAction";
------ Solution ------------------------------------ --------
fourth floor, note the people using struts2 tag
landlord you know what causes it?

<action name="loginAction" class="chapter8.LoginRegisterAction" method="register">
<action name="registerAction" class="chapter8.LoginRegisterAction" method="register">
solve the problem, use a wildcard before you do not have the requested action wildcards were implored once, and then changed to a wildcard in the form, no problem.
but do not know the specific reasons why?

I do not know, the first time without a wildcard request, then switch to a wildcard, you can, do not know the environmental issues?
------ For reference only -------------------------------------- -
never encountered before, I do not know how you get, there is definitely a problem here just like that. . Investigation it yourself slowly
