Re: does anyone fancy testing the security on my test application?
A lot of your problems are because you don't seem to have any idea how Java enterprise or web applications (of any kind) work with sessions - which is a totally separate issue from GWT. I suggest reading up on this prior to trying to use sophisticated frameworks like GWT/GAE. It is usually better to understand the basics of the underlying technology prior to using the most abstract ones. 1) You do not need to send any session id (unless you have some application token - to mitigate XSRF attacks for example). The web container will send the session id in the response header. This session id is kept in the browser memory. The browser maps the cookie id to the originating domain. When making requests to the originating domain, the browser automatically will put the session id in the request headers. Look at the response/request headers yourself. 2) You do not 'set a timeout' on a session id or touch it or whatever else you think you do. This is typically a server/domain configuration parameter. Prior to worrying about regenerating session ids during the course of a session - learn the basics.

Essentially all I need is an interim solution until GAE supports SSL.

Regarding the 5 points (Which I think we can now cut down to just one (the use of sessions) going forward!) 1. I understand that any kind of encryption on the client is effectively pointless without SSL, but its always going to be better than nothing! A bit like saying that hding your front door key under a rock in your neighbours front garden is no different to leaving it in your front door 2. I figured TLS was something like SSL, either way its not on GAE yet, so I cant use it yet! 3. My passwords are being salted and hashed (jBcrypthttp://www.mindrot.org/projects/jBCrypt/) before being stored. 4. 5. Still not sure i get how sessions really work. Ill keep reading and trying to figure it out. But surely at some point I still need to send the session ID from the server to the client right? As far as I can tell so far, the session ID is generated on the server, so the right thing to do it set a timeout on that sessionID and touch it every time the user makes a call to the server, making sure that the sessionID has not timed out. There are mentions in various places that you should refresh/regenerate the sessionID on a regular basis during a logged in session, to keep it fresh.

You cannot have security without ssl. You cannot have a custom domain *and* ssl *and* GAE (because it is prohibitively expensive for google). And you have already starred the GAE issue that speaks about ithttp://code.google.com/p/googleappengine/issues/detail?id=792, so there really isn't anything new for me to add. If you cannot use google's authentication, and if you can't use any of the (not-so-secure) workarounds described in that issue, I am afraid there is no way you can use GAE. I'd recommend discussing this in GAE discussion thread to get ideas from people. Either that, or just wait till GAE starts supporting SSL. Additional responses to your comments 1. It doesn't matter what encryption method you use on client side; it may be the most secure algo on earth. The problem is with the key management. JS code needs the key to encrypt. And if it is in the JS code, an attacker will always be able to get it. Ofuscation is just a very minor hurdle, its easy to read through it. 2. TLS is transport layer securityhttp://en.wikipedia.org/wiki/Transport_Layer_Security, which is essentially the new SSL. 3. On the server side as well - you should NOT encrypt passwords. Encryption means there is a way to decrypt and recover the password. If you can decrypt it, an attacker will find a way as well. The recommended way to store passwords is to Salt and Hash themhttp://www.aspheute.com/english/20040105.asp . 4. Sessions can loosely be described as 'per-user-server-side-hashmap'. The server automatically creates a cookie 'jsessionid' to track the user. So when you call request.getSession(), the container gets the session id from the jsessionid cookie and then gets the state corresponding to

Its almost never a javascript problem but a dom problem or its just a variation from how java works. Additionally, there is no inherent barrier to writing large apps in js any more than there is in java. The determining factor as to whether we'll use GWT will be how we want to build our dev team. As it is, our java developers are quite busy so i couldn't understand why we'd saddle them with more responsibility. That said, its a decision for the people above me. I'm not sure if its an inherent part of the approach but I fault GWT for largely ignoring page based content loading and navigation. It would be preferable if the content was loaded into an html page before any js was attached. GWT v3? And one more outstanding question - how GWT would relate to our existing codebase which is a mix of spring/jsp and xslt - yes, its a mess.

There seems to be two schools of thought: 1/ Try and reuse classes on both server and client sides which means exporting server logic to clients and vice versa 2/ Separating client and server logic and evolving the two separately At first I tried to do the former but I didn't like it: it's just not clean IMHO. What I'm trying to do now is focus on the service interface offered by the server to the client. Using Google App Engine helps this discipline. I define the service interface in terms of actions: 'Create new user', 'Transfer X from account x to account y', 'Get Employee details'. I'm at the frustrating phase that there's a lot of similar objects on both sides of the fence. But, over time, I'm seeing these diverge and evolve differently solving their own use cases without the restraint of trying to maintain a one-size-fits-all approach. In many of my core server-side and persistent objects: Employee, Account, etc., I have/had a method: EmployeeVo Employee.toVo(): i.e. to value object (as opposed to toString()). But, as my use cases become more refined I find that things evolve to having a Person object with toUserVo(), toEmployee() and toCustomerVo() methods that create client side objects that are shipped out to log in, update employee details or have a customer select a shipping address.

Re: show/hide widget based on user's credentials
This is correct, the RPC must also verify user permissions. The easiest way to do this is to keep the 'user validation/permission' code the same on the client and on the server. This can easily be accomplished in GWT since the client code is Java compiled to JavaScript. BTW, you should be doing the same with your input validation code. In my applications we give the client the user's roles and it uses them to decide which parts of the application the user can access. However, ALL RPCs are subject to the same checks so some clever guy cannot just reverse engineer the javascript RPCs and call methods without having any real roles. On Jun 23, 6:55 pm, ailinykh ailin...@gmail.com wrote: I understand that. But you can't trust the client. If someone who has read only access tries to write, server has to reject such request.

I have tables in a database for users, roles, and rights. And I have tables that link them together users_roles and roles_rights. When the user logs in, and authentication is complete, the user data is retrieved along with the roles the user belongs to and the rights that belong to each role. The roles and rights are added to the user and sent back to the client. From that point on, the application can just query the user object for everything that it needs to know about the user.

The user object is only retrieved from the server once since it is not stored anywhere (other than in memory) on the client side.

This is just one step more protection, but should be effective in prevent normal users from forging the request just by using plugin in firefox. GWT has already obfuscated the javascript source code when compiling, this is great. I was thinking maybe we can take one step further to encrypt the data (only for sensitive information rpc.) We will protect the data / request from server side, but to let clients able to rest assure, I am just trying to look out any way we can implement the encryption in GWT.

Re: Dealing with session timeout and container managed security
I handle this in the following way: Use a servlet filter to check the status of the authentication. Check the URL requested (this can be done using a specific kind of filter mapping and initialization parameter), if it is a GWT request then send back an encoded exception that the GWT client will understand. If it is a request for a 'normal' html/jsp/etc then forward to an error page.

Hence, in my web.xm I protect access to the GWT application like so: security-constraint web-resource-collection web-resource-namemy app/web-resource-name url-pattern/app/*/url-pattern http-methodGET/http-method http-methodPOST/http-method http-methodPUT/http-method http-methodDELETE/http-method /web-resource-collection auth-constraint role-name*/role-name /auth-constraint /security-constraint login-config auth-methodFORM/auth-method form-login-config form-login-page/public/login.jsp/form-login-page form-error-page/public/login.jsp?retry=true/form-error-page /form-login-config /login-config security-role role-name*/role-name /security-role So, the application (host/bootstrap page, RPC Servlet, etc.) is in the app folder and the login form (login.jsp) is in the public folder. This works flawlessly except for the session timeout use case. The application sends an RPC request to /app/AppServlet, the Servlet container requires authentication because the session had timed out and dutifully *forwards* to the login page. Hence, the result of the request is not some RPC/JSON/XML object as expected by the client but the login page HTML structure. The client simply isn't prepared for that and freezes i.e. doesn't do anything. I believe that on the server side everything is set up correctly. If the session timed out the requests don't even reach the RPC Servlet because it's intercepted by the container, fine. But how do you deal with this in the client? Should one write some custom AsyncCallback class that handles the reponse sent by the container? Thanks for your feedback.

Re: Sequential workflow in an asynchronous GWT world
Making an async call appear to be sequential is easy, just block or fade out or have a pop up progress bar until the async operation completes. On Mar 4, 10:15 pm, rlaferla robertlafe...@comcast.net wrote: How is everyone managing to implement sequential workflows when GWT only allows async calls? I have a series of panels that user must respond to in sequence and their answers may lead to a different path of panels (warnings, error panels, etc..) I think every GWT programmer working on a large project must have run into this. I'm interested in what strategies/ techniques/code you used to help keep the complexity down. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: How to log/audit/track GWT RPC calls?
Here are some options: 1) Using a servlet filter mapped to the URL pattern of your GWT servlets 2) Log yourself inside of the GWT servlet Matt On Jan 27, 4:01 pm, ka1n leskap...@gmail.com wrote: I'd like to track the usage of my GWT application.

Re: How to Debug GWT code using eclipse Remote Debugging feature
Once compiled into JavaScript you cannot use a Java remote debugger on your GWT project. You can debug using hosted mode, see the docs.

Servlet filter compression interfere with GWT RPC?
Hello all, Assume the following: 1) A GWT application using RPC 2) A servlet filter that dynamically gzip's HttpServletResponses based on file size Given that GWT-RPC already will compress responses, will the response potentially be compressed twice? If so, will this have any impact? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
