Struts 2 and an array of textfields
How do i handle an array of textfields?

I'm having trouble understanding how ActionSupport works. I've extended ActionSupport to handle a form page. If the from contains errors (ie: i have an amount field mapped like s:text name=invoice.amount/ and the user types in asdf) the action mapped to result type execute is never called and, even though the form si set to not perform validation.

Add something like this to your action
public void validate() {
User user = getUser();
if (StringUtils.isBlank(user.getName())) {
addActionError(getText(user.name.empty));
}
if (StringUtils.isBlank(user.getAddress())) {
addActionError(getText(user.address.empty));
}
}

[s2]struts-2-spring-2-jpa-ajax tutorial
I've started learning struts based on this tutorial which (from my limited experience) is a good starting point. There's on problem for me though. It gets frustrating implementing all my persistence related calls in a service class. Is there a way to instantiate my action classes with an EntityManager, so that i can perform simple persistence related jobs directly in my actions? ... Is this a violation of struts framework concepts? Thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[S2] action mappings help
I'm trying to create an index with an action mapped to it for a subfolder in my webapp. The ideea was to create a index.jsp file that has: jsp:forward page=/myapp/subfolder/welcome.action/ so it redirects me to a mapped action. The problem is that even though the url is correct, i get a The requested resource (/myapp/subfolder/welcome.action) is not available from my server.

Re: JAAS struts 2 Tutorial?
I would like a tutorial on integrating jaas in struts2 too. Or rather
than a tutorial, i would like to see some working code. I've done a lot
of reading (i'm new to java web applications, it's been only a month
since i've started) and i have some understanding on how this should
work but i just can't picture it yet in a real app.
I know I'm not being helpful here, sorry. But if anyone wants to write a
tutorial on this, it would be greatly appreciated

Hello Tom,
Thanks for your continued input. The application isn't simple, it is
a J2EE application which will serve a large number of users (users
will be using Web Browser or Mobile Device to access the application).
Based on the help I got on this list, I have been successful in
setting up JAAS and authenticating the user.
Now I am just not sure if the user credentials are being kept.
Following is the code I wrote which processes the user's login. Can
you see what I am missing? I have placed the following code in the
execute method of my action, perhaps it isn't the right place?
Subject subject;
Set principalList;
String returnValue = SUCCESS;
try
{
SecurityAssociationHandler handler = new
SecurityAssociationHandler();
SimplePrincipal user = new SimplePrincipal(username);
handler.setSecurityInfo(user, password.toCharArray());
LoginContext loginContext = new LoginContext(ContentPlatform,
(CallbackHandler) handler);
loginContext.login();
subject = loginContext.getSubject();
principalList = subject.getPrincipals();
principalList.add(user);
System.out.println(o0o0o subject:
+ subject);
System.out.println(o0o0o principle:
+ principalList);
}
catch (LoginException e)
{
e.printStackTrace();
returnValue = ERROR;
}
return returnValue;

If it's simple application, you dont need JAAS, You
can do it via just session management isnt it? You
might need user, role, user-role threee tables on
database thats it :)
If you are using Application server like Jboss, the
server itself got inbuilt features, which is
altogether a different discussion.
If the application is simple, do not make it
complicated,
we use JASS with CAS central authentication service
which provided SSO features.
hope this helps

Each employee may have a single company. Also each employee has a user (which is used by tomcat for authentication/authorization) and i want to set some session values after a login (like current company and current employee). Since I can't intercept the login form (which goes to j_security_check) where should i put the code for setting those session values?
