• How to serialize Java primitives using Jersey REST

  - by Olvagor

  In my application I use Jersey REST to serialize complex objects. This works quite fine. But there are a few method which simply return an int or boolean. Jersey can't handle primitive types (to my knowledge), probably because they're no annotated and Jersey has no default annotation for them. I worked around that by creating complex types like a RestBoolean or RestInteger, which simply hold an int or boolean value and have the appropriate annotations. Isn't there an easier way than writing these container objects?

• REST API unauthenticated requests exception based on the User-Agent

  - by Shay Tsadok

  Hi All, I am developing a REST API that supports two kinds of authentication protocols: login form authentication - for browser based clients. Simple Basic authentication - for non-browser clients. I developed a flow in which unauthenticated requests redirected to the "login form", the problem is that this is an undesired behavior for non-borwser clients! I thought to solve it by decide according to the "User-Agent" what to do: browsers will be redirected to the "login form" and non-browser clients will get the standard 401:Basic Authentication. A. What do you think about this solution? B. Is there a standard way in Java to check if the request came from browser, or do i need to develop this kind of mechanism by my own? Thanks in advance!

• rails, rest, render different action with responds to

  - by Sam

  Maybe my logic is not restful or know if this is how you would do it but this is what I am trying to do. I'm getting a category inside a category controller and then once I get that category I want to return to an index page in a different controller but keep that @category and the Category.busineses. Before rest I would have just done this: render :controller = "businesses" and it would have rendered the view of the index action in that controller. now in my respond_to block I have this format.html {redirect_to(business_path)} # index.html.erb format.xml { render :xml => @businesses } but of course with a render it looses the instance variable and starts with a new action. So what I want to do is render the action instead of redirecting to that action. is this possible?

• ASP.net error message when using REST starter kit

  - by jonhobbs

  Hi all, I've written some code using the REST starter kit and it works fine on my development machine. However, when I upload it to our server the page gives me the following error message... CS1684: Warning as Error: Reference to type 'System.Runtime.Serialization.Json.DataContractJsonSerializer' claims it is defined in 'c:\WINNT\assembly\GAC_MSIL\System.ServiceModel.Web\3.5.0.0__31bf3856ad364e35\System.ServiceModel.Web.dll', but it could not be found I've removed code line by line and it appears that the following line of code is triggering the error... HttpContent newOrganizationContent = HttpContentExtensions.CreateXmlSerializable(newOrganizationXml); Really haven't got a clue how to fix it. I assumed it might be because it needs a newer version of the framework to run, but looking in IIS it says it's running version 2.0.50727 which I think is the lates version because it says that even when we're using framework 3.5 Very confused, any ideas?

• JSONP Implications with true REST

  - by REA_ANDREW

  From my understanding JSONP can only be achieved using the GET verb. Assuming this is true which I think it is, then this rules out core compliance with true REST in which you should make use of different verbs i.e. GET,PUT,POST,DELETE etc... for different and specific purposes. My question is what type of barriers am I likely to come up against if I where to say allow updating and deleting of resources using a JSONP service using a get request. Is it better practice to offer a JSON service and state that the user will need a server side proxy to consume using JavaScript XDomain? Cheers , Andrew

• WCF REST Does Not Contain All of the Relative File Path

  - by Brandon

  I have a RESTful WCF 3.5 endpoint as such: System.Security.User.svc This is supposed to represent the namespace of the User class and is desired behavior by our client. I have another endpoint I created for testing called: Echo.svc I am writing an overridden IHttpModule and in my module, I follow what almost everyone does by doing: string path = HttpContext.Current.Request.AppRelativeCurrentExecutionFilePath; If I make a call to: http://localhost/services/Echo/test My path variable has a value of '~/echo/test' However, when I make a call to: http://localhost/services/System.Security.User/test My path variable has a value of '~/system.security.user' In my 2nd situation, it is stripping off the '/test' on the end of any endpoint that contains multiple periods. This is undesired behavior and the only solution I have found to fixing this is some ugly string manipulation using the property which does contain the complete URL path: string rawPath = HttpContext.Current.Request.RawUrl; This returns '/services/system.security.user/test'. Does anyone know why my first situation does not return the rest of the URL path for endpoints that contain multiple periods in the name?

• Multimedia content in REST responce(XML/JSON)

  - by Koushik

  In my thesis I need to test different architectures. A request to a REST web service developed using Apache CXF and Spring MVC with MySQL as back end serving references(a field in database) to images,audio and video files stored in file system. In the response message, what is the best method to send the content to the client(another application using the service which I developed). URI: http://www.filmservices.com/film/{id} A client here is not the end user. Send the encoded hyperlink's(where the content is stored in the file system) to the client, so that the client renders the response and displays it to the browser. Use Base64 to encode the message(image,audio,video) and send it to the client. Main concern is performance.

• Wrap MemoryStream in a using block REST WCF

  - by Mark

  I'm learning REST to implement some Services with WCF. I implemented an example with a MemoryStream. Because MemoryStream is Disposable I wrapped it in a using. When I do this I sometimes can see the xml response in the browser (IE8) and sometimes it will just show me the following Errormessage: The download of the specified resource has failed. Error processing resource 'http://localhost:8889/SimpleGetService/'. Why does this occur? When I don't wrap it in a using, I never seem to get the error.

• Spring 3.0 REST implementation or Jersey?

  - by hnilsen

  Hi, SO! I'm currently trying to figure out which implementation of JSR-311 I'm going to recommend further up the food chain. I've pretty much narrowed it down to two options - Spring 3.0 with it's native support for REST - or use Sun's own Jersey (Restlets might also be an option). To me it doesn't seem to be much of a difference in the actual syntax, but there might be issues with performance that I haven't figured out yet. The service is meant to replace some heavy-duty EJB's and make a RESTful Webservice instead. The load is expected to be rather high, up in the 100k users per day (max) range, but will be seriously load balanced. Thanks for all your insights.

• How to model file system operations with REST?

  - by massive

  There are obvious counterparts for some of file systems' basic operations (eg. ls and rm), but how would you implement not straightforwardly RESTful actions such as cp or mv? As answers to the question REST services - exposing non-data “actions” suggest, the preferred way of implementing cp would include GETting the resource, DELETing it and PUTting it back again with a new name. But what if I would need to do it efficiently? For instance, if the resource's size would be huge? How would I eliminate the superfluous transmission of resource's payload to client and back to the originating server? Here is an illustration. I have a resource: /videos/my_videos/2-gigabyte-video.avi and I want copy it into a new resource: /videos/johns_videos/copied-2-gigabyte-video.avi How would I implement the copy, move or other file system actions the RESTful way? Or is there even a proper way? Am I doing it all wrong?

• @Path and regular expression (Jersey/REST)

  - by Castanho

  Hi there! I'm using Jersey in a REST project and I'm needing to use regular expression. Digging about it is simple like: @Path("/resources) public class MyResource { @GET @Path("{subResources:.*}/bar") public String get() {...} } But, I'm only capable of using regex if in my @Path contains a variable or text value, example: @Path("{SubResource1}/{subResources:.*}/bar") Or @Path("hardCodeString/{subResources:.*}/bar") Today I could run with this solution of a variable, but is not oK for my perspective. Question Does anyone have worked with something related? I'm doing something wrong? I think that this could be a bug, when working with more then one @Path, one in the Class and other in the Method. Any tips is appreciated! Regards

• Oracle Coherence & Oracle Service Bus: REST API Integration

  - by Nino Guarnacci

  This post aims to highlight one of the features found in Oracle Coherence which allows it to be easily added and integrated inside a wider variety of projects.  The features in question are the REST API exposed by the Coherence nodes, with which you can interact in the wider mode in memory data grid.Oracle Coherence and Oracle Service Bus are natively integrated through a feature found in the Oracle Service Bus, which allows you to use the coherence grid cache during the configuration phase of a business service. This feature allows you to use an intermediate layer of cache to retrieve the answers from previous invocations of the same service, without necessarily having to invoke the real business service again. Directly from the web console of Oracle Service Bus, you can decide the policies of eviction of the objects / answers and define the discriminating parameters that identify their uniqueness.The coherence REST APIs, however, allow you to integrate both products for other necessities enabling realization of new architectures design.  Consider coherence’s node as a simple service which interoperates through the stardard services and in particular REST (with JSON and XML). Thinking of coherence as a company’s shared service, able to have an implementation of a centralized “map and reduce” which you can access  by a huge variety of protocols (transport and envelopes).An amazing step forward for those who still imagine connectors and code. This type of integration does not require writing custom code or complex implementation to be self-supported. The added value is made unique by the incredible value of both products independently, and still more out of their simple and robust integration.As already mentioned this scenario discovers a hidden new door behind the columns of these two products. The door leads to new ideas and perspectives for enterprise architectures that increasingly wink to next-generation applications: simple and dynamic, perhaps towards the mobile and web 2.0.Below, a small and simple demo useful to demonstrate how easily is to integrate these two products using the Coherence REST API. This demo is also intended to imagine new enterprise architectures using this approach.The idea is to create a centralized system of alerting, fed easily from any company’s application, regardless of the technology with which they were built . Then use a representation standard protocol: RSS, using a service exposed by the service bus; So you can browse and search only the alerts that you are interested on, by category, author, title, date, etc etc.. The steps needed to implement this system are very simple and very few. Here they are listed below and described to be easily replicated within your environment. I would remind you that the demo is only meant to demonstrate how easily is to integrate Oracle Coherence and the Oracle Service Bus, and stimulate your imagination to new technological approaches.1) Install the two products: In this demo used (if necessary, consult the installation guides of 2 products)  - Oracle Service Bus ver. 11.1.1.5.0 http://www.oracle.com/technetwork/middleware/service-bus/downloads/index.html - Oracle Coherence ver. 3.7.1 http://www.oracle.com/technetwork/middleware/coherence/downloads/index.html 2) Because you choose to create a centralized alerting system, we need to define a structure type containing some alerting attributes useful to preserve and organize the information of the various alerts sent by the different applications. Here, then it was built a java class named Alert containing the canonical properties of an alarm information:- Title- Description- System- Time- Severity 3) Therefore, we need to create two configuration files for the coherence node, in order to save the Alert objects within the grid, through the rest/http protocol (more than the native API for Java, C + +, C,. Net). Here are the two minimal configuration files for Coherence:coherence-rest-config.xml resty-server-config.xml This minimum configuration allows me to use a distributed cache named "alerts" that can  also be accessed via http - rest on the host "localhost" over port "8080", objects are of type “oracle.cohsb.Alert”. 4) Below  a simple Java class that represents the type of alert messages: 5) At this point we just need to startup our coherence node, able to listen on http protocol to manage the “alerts” cache, which will receive incoming XML or JSON objects of type Alert. Remember to include in the classpath of the coherence node, the Alert java class and the following coherence libraries and configuration files:  At this point, just run the coherence class node “com.tangosol.net.DefaultCacheServer”advising you to set the following parameters:-Dtangosol.coherence.log.level=9 -Dtangosol.coherence.log=stdout -Dtangosol.coherence.cacheconfig=[PATH_TO_THE_FILE]\resty-server-config.xml 6) Let's create a procedure to test our configuration of Coherence and in order to insert some custom alerts in our cache. The technology with which you want to achieve this functionality is fully not considerable: Javascript, Python, Ruby, Scala, C + +, Java.... Because the protocol to communicate with Coherence is simply HTTP / JSON or XML. For this little demo i choose Java: A method to send/put the alert to the cache: A method to query and view the content of the cache: Finally the main method that execute our methods:  No special library added in the classpath for our class (json struct static defined), when it will be executed, it asks some information such as title, description,... in order to compose and send an alert to the cache and then it will perform an inquiry, to the same cache. At this point, a good exercise at this point, may be to create the same procedure using other technologies, such as a simple html page containing some JavaScript code, and then using Python, Ruby, and so on.7) Now we are ready to start configuring the Oracle Service Bus in order to integrate the two products. First integrate the internal alerting system of Oracle Service Bus with our centralized alerting system based on coherence node. This ensures that by monitoring, or directly from within our Proxy Message Flow, we can throw alerts and save them directly into the Coherence node. To do this I choose to use the jms technology, natively present inside the Oracle Weblogic / Service Bus. Access to the Oracle WebLogic Administration console and create and configure a new JMS connection factory and a new jms destination (queue). Now we should create a new resource of type “alert destination” within our Oracle Service Bus project. The new “alert destination” resource should be configured using the newly created connection factory jms and jms destination. Finally, in order to withdraw the message alert enqueued in our JMS destination and send it to our coherence node, we just need to create a new business service and proxy service within our Oracle Service Bus project.Our business service is responsible for sending a message to our REST service Coherence using as a method action: PUT Finally our proxy service have to collect all messages enqueued on the destination, execute an xquery transformation on those messages  in order to translate them into valid XML / alert objects useful to be sent to our coherence service, through the newly created business service. The message flow pipeline containing the xquery transformation: Incredibly,  we just did a basic first integration between the native alerting system of Oracle Service Bus and our centralized alerting system by simply configuring our coherence node without developing anything.It's time to test it out. To do this I create a proxy service able to generate an alert using our "alert destination", whenever the proxy is invoked. After some invocation to our proxy that generates fake alerts, we could open an Internet browser and type the URL  http://localhost: 8080/alerts/  so we could see what has been inserted within the coherence node. 8) We are ready for the final step.  We would create a new message flow, that can be used to search and display the results in standard mode. To do this I choosen the standard representation of RSS, to display a formatted result on a huge variety of devices such as readers for the iPhone and Android. The inquiry may be defined already at the time of the request able to return only feed / items related to our needs. To do this we need to create a new business service, a new proxy service, and finally a new XQuery Transformation to take care of translating the collection of alerts that will be return from our coherence node in a nicely formatted RSS standard document.So we start right from this resource (xquery), which has the task of transforming a collection of alerts / xml returned from the node coherence in a type well-formatted feed RSS 2.0 our new business service that will search the alerts on our coherence node using the Rest API. And finally, our last resource, the proxy service that will be exposed as an RSS / feeds to various mobile devices and traditional web readers, in which we will intercept any search query, and transform the result returned by the business service in an RSS feed 2.0. The message flow with the transformation phase (Alert TO Feed Items): Finally some little tricks to follow during the routing to the business service, - check for any queries present in the url to require a subset of alerts  - the http header "Accept" to help get an answer XML instead of JSON: In our little demo we also static added some coherence parameters to the request:sort=time:desc;start=0;count=100I would like to get from Coherence that the results will be sorted by date, and starting from 1 up to a maximum of 100.Done!!Just incredible, our centralized alerting system is ready. Inheriting all the qualities and capabilities of the two products involved Oracle Coherence & Oracle Service Bus: - RASP (Reliability, Availability, Scalability, Performance)Now try to use your mobile device, or a normal Internet browser by accessing the RSS just published: Some urls you may test: Search for the last 100 alerts : http://localhost:7001/alarmsSearch for alerts that do not have time set to null (time is not null):http://localhost:7001/alarms?q=time+is+not+nullSearch for alerts that the system property is “Web Browser” (system = ‘Web Browser’):http://localhost:7001/alarms?q=system+%3D+%27Web+Browser%27Search for alerts that the system property is “Web Browser” and the severity property is “Fatal” and the title property contain the word “Javascript”  (system = ‘Web Broser’ and severity = ‘Fatal’ and title like ‘%Javascript%’)http://localhost:8080/alerts?q=system+%3D+%27Web+Browser%27+AND+severity+%3D+%27Fatal%27+AND+title+LIKE+%27%25Javascript%25%27 To compose more complex queries about your need I would suggest you to read the chapter in the coherence documentation inherent the Cohl language (Coherence Query Language) http://download.oracle.com/docs/cd/E24290_01/coh.371/e22837/api_cq.htm .

• Send large JSON data to WCF Rest Service

  - by Christo Fur

  Hi I have a client web page that is sending a large json object to a proxy service on the same domain as the web page. The proxy (an ashx handler) then forwards the request to a WCF Rest Service. Using a WebClient object (standard .net object for making a http request) The JSON successfully arrives at the proxy via a jQuery POST on the client webpage. However, when the proxy forwards this to the WCF service I get a Bad Request - Error 400 This doesn't happen when the size of the json data is small The WCF service contract looks like this [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] [OperationContract] CarConfiguration CreateConfiguration(CarConfiguration configuration); And the DataContract like this [DataContract(Namespace = "")] public class CarConfiguration { [DataMember(Order = 1)] public int CarConfigurationId { get; set; } [DataMember(Order = 2)] public int UserId { get; set; } [DataMember(Order = 3)] public string Model { get; set; } [DataMember(Order = 4)] public string Colour { get; set; } [DataMember(Order = 5)] public string Trim { get; set; } [DataMember(Order = 6)] public string ThumbnailByteData { get; set; } [DataMember(Order = 6)] public string Wheel { get; set; } [DataMember(Order = 7)] public DateTime Date { get; set; } [DataMember(Order = 8)] public List<string> Accessories { get; set; } [DataMember(Order = 9)] public string Vehicle { get; set; } [DataMember(Order = 10)] public Decimal Price { get; set; } } When the ThumbnailByteData field is small, all is OK. When it is large I get the 400 error What are my options here? I've tried increasing the MaxBytesRecived config setting but that is not enough Any ideas?

• REST API Best practice: How to accept as input a list of parameter values

  - by whatupwilly

  Hi All, We are launching a new REST API and I wanted some community input on best practices around how we should have input parameters formatted: Right now, our API is very JSON-centric (only returns JSON). The debate of whether we want/need to return XML is a separate issue. As our API output is JSON centric, we have been going down a path where our inputs are a bit JSON centric and I've been thinking that may be convenient for some but weird in general. For example, to get a few product details where multiple products can be pulled at once we currently have: http://our.api.com/Product?id=["101404","7267261"] Should we simplify this as: http://our.api.com/Product?id=101404,7267261 Or is having JSON input handy? More of a pain? We may want to accept both styles but does that flexibility actually cause more confusion and head aches (maintainability, documentation, etc.)? A more complex case is when we want to offer more complex inputs. For example, if we want to allow multiple filters on search: http://our.api.com/Search?term=pumas&filters={"productType":["Clothing","Bags"],"color":["Black","Red"]} We don't necessarily want to put the filter types (e.g. productType and color) as request names like this: http://our.api.com/Search?term=pumas&productType=["Clothing","Bags"]&color=["Black","Red"] Because we wanted to group all filter input together. In the end, does this really matter? It may be likely that there are so many JSON utils out there that the input type just doesn't matter that much. I know our javascript clients making AJAX calls to the API may appreciate the JSON inputs to make their life easier. Thanks, Will

• WCF REST with jQuery AJAX - removing/working around same origin policy

  - by csauve

  So I'm trying to create a C# WCF REST service that is called by jQuery. I've discovered that jQuery requires that AJAX calls are made under the same origin policy. I have a few questions for how I might proceed. I am already aware of; 1. The hacky solution of JSONP with a server callback 2. The way too much server overhead of having a cross-domain proxy. 3. Using Flash in the browser to make the call and setting up crossdomain.xml at my WCF server root. I'd rather not use these because; 1. I don't want to use JSON, or at least I don't want to be restricted to using it 2. I would like to separate the server that serves static pages from the one that serves application state. 3. Flash in this day in age is out of the question. What I'm thinking: is there anything like Flash's crossdomain.xml file that works for jQuery? Is this "same-origin" policy a part of jQuery or is it a restriction in specific browsers? If it's just a part of jQuery, maybe I'll try digging in the code to work around it.

• Unknown error when submit a REST request to Liferay json API

  - by r.rodriguez

  I'm writing an script in Python to automatically update the structures in my Liferay portal and I want to do it via the json REST API. I make a request to get an structure (method getStructure), and it worked. But when I try to do an structure update in the portal it shows me the following error: ValueError: Content-Length should be specified for iterable data of type class 'dict' {'serviceContext': "{'prueba'}", 'serviceClassName': 'com.liferay.portlet.journal.service.JournalStructureServiceUtil', 'name': 'FOO', 'xsd': '... THE XSD OBTAINED VIA JSON ...', 'serviceParameters': '[groupId,structureId,parentStructureId,name,description,xsd,serviceContext]', 'description': 'FOO Structure', 'serviceMethodName': 'updateStructure', 'groupId': '10133'} What I'm doing is the next: urllib.request.Request(url = URL, data = data_update, headers = headers) URL is http://localhost:8080/tunnel-web/secure/json The headers are configured with basic authentication (it works, it is tested with the getStructure method). Data is: data_update = { "serviceClassName" : "com.liferay.portlet.journal.service.JournalStructureServiceUtil", "serviceMethodName" : "updateStructure", "serviceParameters" : "[groupId,structureId,parentStructureId,name,description,xsd,serviceContext]", "groupId" : 10133, "name" : FOO, "description" : FOO Structure, "xsd" : ... THE XSD OBTAINED VIA JSON ..., "serviceContext" : "{}" } Does anybody know the solution? Have I to specify the length for the dictionary and how? Or this is a bug?

• secure rest API for running user "apps" in an iframe

  - by Brian Armstrong

  I want to let users create "apps" (like Facebook apps) for my website, and I'm trying to figure out the best way to make it secure. I have a REST api i want to run the user apps in an iframe on my own site (not a safe markup language like FBML) I was first looking at oAuth but this seems overkill for my solution. The "apps" don't need to be run on external sites or in desktop apps or anything. The user would stay on my site at all times but see the user submitted "app" through the iframe. So when I call the app the first time through the iframe, I can pass it some variables so it knows which logged in user is using it on my site. It can then use this user session in it's own API calls to customize the display. If the call is passed in the clear, I don't want someone to be able to intercept the session and impersonate the user. Does anyone know a good way to do this or good write up on it? Thanks!

• HTTP POST prarameters order / REST urls

  - by pq

  Let's say that I'm uploading a large file via a POST HTTP request. Let's also say that I have another parameter (other than the file) that names the resource which the file is updating. The resource cannot be not part of the URL the way you can do it with REST (e.g. foo.com/bar/123). Let's say this is due to a combination of technical and political reasons. The server needs to ignore the file if the resource name is invalid or, say, the IP address and/or the logged in user are not authorized to update the resource. Looks like, if this POST came from an HTML form that contains the resource name first and file field second, for most (all?) browsers, this order is preserved in the POST request. But it would be naive to fully rely on that, no? In other words the order of HTTP parameters is insignificant and a client is free to construct the POST in any order. Isn't that true? Which means that, at least in theory, the server may end up storing the whole large file before it can deny the request. It seems to me that this is a clear case where RESTful urls have an advantage, since you don't have to look at the POST content to perform certain authorization/error checking on the request. Do you agree? What are your thoughts, experiences?

No serial numbers, no manual versioning, simple... avro is a good example for this. Works with Java and Python Supports both fast binary prorocol, as well as HTTP based restful style. I'd like to be able to use it for both backend-to-backend communication (java-java or python-java) as well as frontend-to-backend communication (javascript to java). The rest support needs to include &param=value input as get/post requests (configurable per request) and output in three possible formats: json, jsonp, XML. Compact, fast, backward compatible, easy to upgrade etc... Provides some nice monitoring interfaces such as: JMX, web page status reports (e.g. packets in, packets out, error rate etc) Ops friendly... no need to take the whole site down to release new versions Both sync and asyc communication ... other goodies are welcome... Is there something out there? So far I've looked at thrift and avro and they are both nice in some ways, but don't check all my list. Thanks

• fullcalendar events from REST-ful php server.

  - by biagidp

  I've written a very simple RESTful php server (my first experiment with REST, so feel free to make suggestions) to respond to the fullcalendar events callback. It produces exactly the same string output as the json-events.php file in the fullcalendar json example, but for some reason fullcalendar will not accept my server's output. I've tried messing with the headers because they're different from the ones produced by json-events.php, but I'm not really sure what's awry there, if anything. The code for the server is below: <?php class Listener{ function __construct() { $this->getResource(); $this->buildResponse(); } function getResource(){ $parts = explode('/', $_SERVER["REQUEST_URI"]); $script_name = end(explode('/', $_SERVER["SCRIPT_NAME"])); $this->resource = $parts[array_search($script_name, $parts) + 1]; $this->resource_id = $parts[array_search($script_name, $parts) + 2]; } function buildResponse(){ $method = strtolower($_SERVER["REQUEST_METHOD"]); $this->response_string = $method . ucwords($this->resource); } function getResponse(){ return $this->response_string; } } $listener = new Listener(); $thing = $listener->getResponse(); #$thing(); function getEvents(){ $year = date('Y'); $month = date('m'); echo json_encode(array( array( 'id' => 111, 'title' => "Event1", 'start' => "$year-$month-10", 'url' => "http://yahoo.com/" ), array( 'id' => 222, 'title' => "Event2", 'start' => "$year-$month-20", 'end' => "$year-$month-22", 'url' => "http://yahoo.com/" ) )); } ?> Any input, help or suggestions would be greatly appreciated! Thanks, David
