Hi!
Has anybody succeeded with implementing web.xml Form Login with Vaadin 7.1 (or 7.0)? Basic Login works as expected, but I can’t make Form Login work. Everything I get in browser, instead of the form, is following error:
Failed to load the bootstrap javascript: ./VAADIN/vaadinBootstrap.js
My web.xml contains:
<security-constraint>
<display-name>SecureApplicationConstraint</display-name>
<web-resource-collection>
<web-resource-name>Vaadin application</web-resource-name>
<description>The entire Vaadin application is protected</description>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>
<description/>
<role-name>*</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>FORM</auth-method>
<realm-name>default</realm-name>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/loginError.jsp</form-error-page>
</form-login-config>
</login-config>
“*” role is allowed by allRolesMode=“authOnly” in realm.
I also tried to set my app path (@WebServlet value) to /app/* and put redirecting index.jsp in the main path, but after sucessful login and redirection to /app/ I still get JS error mentioned above… I also tried to remove Servlet 3.0 API annotations (@WebServer) and only use a standard web.xml descriptor, but also no luck here 
Any clues how to make it work?
