worklight j_security_check not found

问题

I'm using Worklight Studio Plugin 6.0.

I am trying to get FormBasedAuthentication working. When I run and deploy my worklight project, the app login page is presented successfully. However when I click on the login button, an error is thrown on the server console:

[ERROR ] FWLSE0048E: Unhandled exception caught: SRVE0190E: File not found: /apps/services/j_security_check [project DojoTest] SRVE0190E: File not found: /apps/services/j_security_check

This directory doesn't exist in the project. I've tried creating another project but it doesn't add the missing folder.

Any advise is appreciated. Thank you in advance.

In form-based authentication it is expected from the server to send a login form in response to a connect attempt (you are not required to display the HTML sent by the server, it's just the response that matters mostly).

Basically, if your app's first screen is the login form and you click some login button and this button does a login attempt, it will first the first time, because only in the first time will the server get a request from the app and the response to that request would be the challenge - the login form.

So you need to make sure that you first connect to the server using WL.Client.connect and only then allow the user to do any login attempts (can be a login button). This is the usual scenario why the above error is given.

Note also that this is not a resource that exists in your Worklight project; it's a resource that exists on the server. This is why you cannot find it.

Please review the authentication concepts and form-based tutorial (and its sample) user documentation: http://www-01.ibm.com/support/knowledgecenter/SSZH4A_6.0.0/com.ibm.worklight.getstart.doc/start/c_gettingstarted.html?cp=SSNJXP
