I need to create a restful service. I have no access to some classes but need to send the same classes in the result. Is there a way to map the object to xml. I tried using org.springframework.oxm.castor.CastorMarshaller but it gives response with extra tags in the xml like
<bean-property-binding-result field-error-count="0" global-error-count="0" error-count="0">
Is there a way to get it done using castor marshaller? If not can anyone redirect to write page
I solved this issue by using velocity templates as xml templates and returning that xml as response for the call.

I am trying to get the form data from a multipart/form-data POST to my ASW Lambda web service via API Gateway.
The HTTP POST has Content-Type "multipart/form-data" and body that is URL encoded. File data is also sent in this post (hence the multipart, I guess).
The web service needs to integrate with a thirdparty service, so changing the format of the POST isn't really an option.
I have seen this thread talking about converting the URL encoded data to JSON object for use in Lambda, but this doesn't do the trick.
I have also tried setting the Integration Request -> Mapping Templates for content type multipart/form-data to Input passthrough. This didn't help either.
I did come across another question about uploading a file using multipart/form-data, but since I'm not interested in the file, just the body, that answer didn't help.
Below find screenshot (sorry) of the captured post via runscope.
If the goal is to use Lambda, you'll need to pass valid JSON to the function. Currently there isn't a way to JSON-ify data inside Api Gateway that comes in as non-JSON data.
Our short term fix (on our backlog) is to provide a variable in the mapping templates to grab the raw input of the request. That way you could do a simple JSON conversion using a template like:
{
"body" : "$input.body"
}
or something like that.
Check out the mapping template reference for more info: http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-mapping-template-reference.html
Edit 4/7 - feature has been released as $input.body
I am working on a SoapUI automation project for Restful service.I'm new to SoapUi and Restful services itself.
I have the Rest API generated in SoapUI. I don't have any sample requests given by the developer so I am working on creating the requests myself. I only have a JSON contract document to refer to which was created for the UI developers. Now according to the specification documents, some get methods in the API's are supposed to have two parameters "token" and "ContextName". However, when I imported the WADL file in SoapUI, the request body only has the "token" parameter. So am I manually supposed to add the other missing parameter in my requests? and is it possible to create a POST(rest test request) in a GET resource?
I don't think you can have multiple body parameters (or if you can, it's certainly not a good practice!). Check to see if the ContextName parameter is a different type of parameter such as a query or path parameter (called template parameter in SoapUI). Here is some info about different types of REST parameters in SoapUI: http://www.soapui.org/rest-testing/understanding-rest-parameters.html
I'm not sure what you mean in your second question. Perhaps you want to write a Test Case with multiple Test Steps (a GET and a POST)? Check out this link: http://www.soapui.org/functional-testing/structuring-and-running-tests.html Also look at the other sections under Functional Testing to learn how to control the flow of test steps.
Given a one page app that uses push state and RESTful backend, we can imagine accessing the listing of a resource at /resourceName (i.e. /users). So /users would create a formated list of users
Now the problem is that this resource JSON or XML feed should also be mapped to /resourceName, so if boot form my application entry point at / then all is good, when navigating to /users the JS router can trigger a Ajax call that get the JSON data. Now the problem is if the URL is pointing directly at /users then i will land on a JSON feed instead of the actual listing. I could route all call to a main entry point and then let the JS router do the work though if i do so the AJAX call to fetch JSON wil brake.
I remember a while ago people adding .json to their json request, or even a GET parameter ?format=json and then having the controller taking different actions. I find that somewhat hacky.. Are there any other ways to go about this?
For that matter i am using laravel4 backend and backboneJS
I think the .json on the end of the request is the best approach. the other approach could be to create a separate endpoint endpoint for api request api.mydomain.com vs www.mydomain.com
What method you use to get a different response depends on how you'd like to go about it. Since you're asking about an opinionated topic (There is no one right answer), here's some options you can explore.
First, here's a good read from Apigee on API design, which covers what I'll write about here. See page 20 on "Support multiple formats"
The Rails way: Append a .json, .xml or other extension at the end of your request and handle that code within Laravel (You may want to use the "before" filter to check the request or Laravel's excellent route parameters, which allow the use of regex to define the route).
You can check the "accept" header in the request and set that header in your ajax calls to "application/json" instead of the default "application/html" to inform your application which format to use in its response. Again, the before or after filters may come in handy to check the request and define the response as appropriate
Create a query string `?format=json" or similar. Same comments as in point 1.
Laravel doesn't have built-in methods to change the response for you. You can, however, fairly easily detect what's being asked and choose which format to return in. It does take some thinking about how you want to accomplish that, however.
Some options off the top of my head:
Use the "before" or "after" filter to check what the request "wants" for a format, and do some transformations on the response to make that work
Extend the request and response class to "automate" this (request class to detect format, response class to transform the response to the correct format)
Hope that helps
It's valid to say which representation do you want. E.g. JSON, XML or binary, depends on what you want and which serializers have you developed.
You framework should support either setting of default representation or if you provide some mapping URL -> method you should be able to say which representation you are going to return - also either by default or taken within some object which represents your request.
I ended up using different endpoints as suggested by #Aaron Saunders. In laravel 4 this is dumb easy to implement using group routes:
app.php:
'domain' => 'whatever.dev',
routes.php:
define('APP_DOMAIN', 'app.' . Config::get('app.domain'));
define('API_DOMAIN', 'api.' . Config::get('app.domain'));
Route::group(array('domain' => API_DOMAIN), function()
{
// API ROUTES
});
Route::group(array('domain' => APP_DOMAIN), function()
{
// VIEW ROUTES
});
Beautiful!
I'm using GWT to develop a web app. I'm currently using AJAX calls to retrieve values from the server. I have following queries regarding to AJAX calls:
Assume: I have an app, name of which is: "Application" and the entry point class is: "entry.java"
I know: the application could be invoked as: http://localhost:8080/Application/entry.html
1. I would like to know what what is the output URL given by gwt.getmodulebaseURL()?
Assume: In the same application I have a service called "ServerValuesService" and its corresponding Async. I have corresponding serviceImpl, which has a method called List < String >search(String) at the server side.
I could retrieve the values from the server as well. However,
2. I would like to know what would be the direct URL to access this service? For Instance, I need to obtain the list of values, by just giving a URL (passing value for the String). i.e. I need to access the method search(String) and retrieve the list just by typing a url such as:
http://localhost:8080/Application/entry/serverValuesService?string="hello"
I'm sure the above URL is wrong. I need to know exact conversion between URL and the corresponding service. Is this possible at all?
Thanks in advance!
1) In your case it will give you http://localhost:8080/Application . Application is your modulename.
2) These services are actually HttpServlets and their URL's are defined in the web.xml file. But Google uses POST method to send your variables and takes care of serialization for you, what you are trying to do is send it via GET method which is as far as I know not implemented by Google RemoteServiceServlet.So I would say no its not possible unless you extend these services to work with GET methods yourself but I don't know if that is possible.
Assume: I have an app, name of which is: "Application" and the entry point class is: "entry.java"
I know: the application could be invoked as: http://localhost:8080/Application/entry.html
The url http://localhost:8080/Application/entry.html is called host page url. In this html page you load your GWT module using a script tag:
<!-- This script tag is what actually loads the GWT module. The -->
<!-- 'nocache.js' file (also called a "selection script") is -->
<!-- produced by the GWT compiler in the module output directory -->
<!-- or generated automatically in hosted mode. -->
<script language="javascript" src="calendar/calendar.nocache.js"></script>
So if you put above example in your entry.html, the module will be loaded from http://localhost:8080/Application/calendar/calendar.nocache.js making http://localhost:8080/Application/calendar/ your module base url.
I would like to know what would be the direct URL to access this
service? For Instance, I need to obtain the list of values, by just
giving a URL (passing value for the String). i.e. I need to access the
method search(String) and retrieve the list just by typing a url
GWT RPC use a custom serialization format to encode requests to the RPC Service on server. The RPC service is implemented as a subclass of RemoteServiceServlet on the server. The RemoteServiceServlet handles the http POST requests, de-serializing the request from client and invvoking appropriate service method of sub-class.
So for directly accessing the service you'll need:
1. The service URL
2. Request payload encoded in GWT's custom serialization format
3. Ability to HTTP POST the payload to the Service URL
1 and 3 are easy to acquire. You already know the URL at which your service is mapped in web.xml. And you can do post from any http client or browser plugins like this. The hard-part would be to generate request payload in GWT's custom serialization format. For simple cases, you can generate a request from your application and capture the raw payload from Firebug, Fiddler or similar tool and simply replay it using your http client.
We're using Grails for building RESTful services which we'll call from browser clients using HTML forms, the problem is that forms only support GET and POST, so we're not sure how to handle PUT and DELETE.
Grails template tags can help you there:
However, issuing a request with a method other than GET or POST from a regular browser is not possible without some help from Grails. When defining a form you can specify an alternative method such as DELETE:
<g:form controller="book" method="DELETE">
..
</g:form>
Grails will send a hidden parameter called _method, which will be used as the request's HTTP method. Another alternative for changing the method for non-browser clients is to use the X-HTTP-Method-Override to specify the alternative method name.
