ruby-on-rails rest
Wondering if I should ALWAYS use the respond_to/format.xxx block in ALL of my actions in ALL of my controllers. This came up because I realized that, for apps using only HTML response format (no respond_to block), I could send some other type of request (say XML) and get a valid response. Is this considered insecure? Feels to me like it is, and it seems that the solution would be to ALWAYS add the respond_to/format.xxx block to EVERY action on EVERY controller even if you are just using HTML

We are are going to be creating some RESTful services which are essentially going to be a passthrough to some ye-olde-fashioned SOAP-based webservices. The SOAP services are more generalized and will used across our entire organization (at least that’s the plan). The RESTful services are tailored to specific clients. This decision was already made and is unfortunately out of my control to change…We’re struggling with how to structure our RESTful resources in a way that makes sense, follows

When I try to consume the WCF Service in MVC 3, I get an error :”The remote server returned an unexpected response: (405) Method Not Allowed.” I created a proxy by adding a service reference to my MVC project. Let me know if you have encountered this issue and have the solution. Please help! I already spent 2 days on it.

web-services rest http-status-codes
Is it to be considered good practice to reuse RFC HTTP Status codes like this, or should we be making up new ones that map exactly to our specific error reasons?We’re designing a web service API around a couple of legacy applications. In addition to JSON/XML data structures in the Response Body, we aim to return HTTP Status Codes that make sense to web caches and developers.But how do you go about mapping different classes of errors onto appropriate HTTP Status codes? Everyone on the team agrees

rest soap communication
We are building a proprietary system involving a client and a server linked over TCP/IP. Occasionally, the server will have some new expected or unexpected information that would be of interest to the client. My understanding is that SOAP and REST are query/response systems that require the client to request something and the server responds back. We need the client to register and the server to respond back if and when the new information is available. Are these protocols capable of such be

I can get consume the resource with a browser, and also with a simple restlet client running in the console. I have modified the code for the JSE client to try to connect

java gwt exception-handling smartgwt
I’ve been working on a project which uses GWT (and SmartGWT), which is (are) new to me.Whenever runtime exceptions are thrown in the client (no RPCs involved) nothing happens. By that I mean the method does not continue executing, there are no alerts, there is nothing in the Javascript error console or the SmartGWT error console.I’m assuming this isn’t normal practice in GWT applications. Where are these errors (e.g. null pointers) normally logged/handled?Thanks in advance.

java firefox smartgwt
Does anyone know a ‘nice’ way to prevent SmartGWT from creating TextItem form items with the spellcheck=”true” set? It’s annoying to get spellcheck markers on name fields etc.The nuclear option is to hack out the problem js code from the smartGWT library, or replace the js method at runtime with: formItem.setAttribute(“getBrowserSpellCheck”, JavaScriptObject.createFunction());But this is clearly not an ideal approach.

I have a GWT application where users keep the browser based side of the application open indefinitely. Every so often we upgrade the application – if the users hit reload in their browsers after this is done then everything goes fine. However what usually happens is that they carry on using the already open version of the application, i.e. a version served before the upgrade, and then experience obscure RPC related errors as the client side Javascript is no longer in sync with what is on the ser
