Error in web.xml file

[Justin Fluff]

I have following code in my web.xml file:

  
 
<?xml version="1.0" encoding="ISO-8859-1"?>

</form-login-config>
</login-config> 
 
</web-app>
 

but when I validate it i get the following error:

The content of element type "web-app" must match "(icon?,display-name?,description?,distributable?,context-param*,servlet*,servlet-mapping*,session-config?,mime-mapping*,welcome-file-list?,error-page*,taglib*,resource-ref*,security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*)".


Any suggestion? How can I correct it.

You have two login-config elements. You can include 0 or 1 login-config element in web-app element. Double-check the DTD for it. login-config? means optional (0 or 1).
