RESTFUL Web Services vs Socket Programming Performance

Hi guys,
I will have an application which will have a service serving about to 30 million users/day and a mean of 5 requests/user.
It means that there will be about 150 million requests per day. I will have two servers behind a load balancer and my clients will be both Java and C++.
I think to implement RESTFUL Web Services but afraid of performance issues.
Did you have a knowledge about the performances of web service and socket programming in such a high loaded project?
Tnx.

Did you have a knowledge about the performances of web service and socket programming in such a high loaded project?It depends on the CPUs, RAM, disks, and network configurations of those servers.
It depends on how the requests are distributed throughout the day.
It depends on how big the requests are and how big the responses are.

Java - rest web services question.

Hi all,
I am new to SOAP and Rest based web services.
In my current standalone application, the request and response payload of a query are in the form of a xml document. This application needs to be accessed by several applications that are written in diffrent programming languages(.net, python etc).
Thus I want my application to be exposed as a web service. Some web services need to be SOAP based and others need not be.
I understand that I need to follow the below steps to make Rest based web service :
1a) I would expose my application interface description and business methods as URIs in a html/xml document.
1b) If client wants to retrieve data, how will he programatically access the associated URI and set the method parameters (if any)?
Also how does he send the request back to my application and how will my application understand it?
1d) Can the code to understand the client request be written in any programming language since Rest does not restrict usage of specific tools.
1f) It looks like the key feature of Rest is to have URIs in the reponse payload xml.
Is this always required? In other words, can the reponse xml be one long xml without URIs to the embedded resources?
Please let me know if Java has any API/tutorials to support the above requirements.
Your input is highly appreciated.
Thanks in advance for your valuable time and interest.

You will be interested in JSR 311 JAX-RS: The JavaTM API for RESTful Web Services. This JSR is in the very early stages. The SWDP (Sun Web Developers Pack) 1.0 contains a very preliminary implementation of RESTBeans which is the basis for this JSR. Download the SWDP and look at the docs/samples in the rest-impl directory. http://developers.sun.com/web/swdp/. Here is a link to some docs on the REST APIs http://developers.sun.com/docs/web/swdp/r1/rest-impl/docs/getting-started.html

HTTP error when trying to access RESTful web service from application

Hi,
We are getting the following error when trying to access a RESTful web service coming from Apex workspace 4.2.1 and Apex listener 2.1:
ORA-29273: HTTP request failed ORA-06512: at "SYS.UTL_HTTP", line 1130 ORA-29024: Certificate validation failure
In the Debug report, besides the above I also see:
error_backtrace: ORA-06512: at "SYS.UTL_HTTP", line 1130 ORA-06512: at "APEX_040200.WWV_FLOW_WEB_SERVICES", line 543 ORA-06512: at "APEX_040200.WWV_FLOW_WEB_SERVICES", line 1164 ORA-06512: at "APEX_040200.WWV_FLOW_PROCESS", line 396
We get that error whether we use https or http in the URI pointing to the web service. When I test the Web Service in Workspace RESTful service GUI, I get the data back. When I go build an application with a report calling the RESTful Web Service I get that error. Both the Application and the Workspace RESTful services are on the same Apex environment and even the same workspace.
What is odd is that I can actually put the URL of the web service into a browser and I get the data: (using the demo hr data in sample RESTful services.)
IN browser-- https://weblogic-dev.edu/apex/ace/hr/empinfo/

Any ideas on what would be causing the Error above in our application?
Thanks,

In reviewing the above error, I think we are realizing that we have to have the Weblogic layer SSL cert (actually the CERT from our BigIP load balancer which also does our SSL termination) imported into the Oracle server wallet where Apex is installed. Am I correct?
PM

We resolved our problem. The Apex Administrative Guide made us realize that we had to set up Wallet path in the Instance. This required working with DBAs to follow the Advanced networking guide to get the wallet set up on our server. We then added that path to the Instance configuration. (Manager Instance --> Instance settings). We ran into another other issue related to our implementation of CAS but were able to resolve that, and 'voila' were able to get the sample RESTful service consumed by our application!!
Now to the task of figuring out how to get Basic Auth working between client application and RESTful web service. If anyone has that working, let us know!!
It would be helpful if in the documentation of the Apex 2.x listener or Apex install/configuration there was clear reference to the above steps required for HTTPS access to RESTful web services.

401 Unauthorized Error When calling a SharePoint REST web service from SharePoint 2013 Workflow

We have our Workflow Manger installed on the same server as our SharePoint 2013 WFE development environment. When creating a SharePoint 2013 Workflow all Calls to a SharePoint 2013 REST web service results in a 401 Unauthorized error.
As an example I created a simple workflow that should return a JSON result. The REST Url returns the results in the browser without error.
Set Variable:webServiceUrl to https://<hostnamedsitecollection>/_vti_bin/client.svc/web/lists/getbytitle('ISR%20Approvers')/Items?$select=Title&$filter=Title%20eq%20%27General%27
then Build{...} Dictionary (Output to Variable:requestHeaders)
then Call [%Variable:webServiceUrl%] HTTP web service with request (ResponseContent to Variable:responseContent |ResponseHeaders to responseHeaders | ResponseStatusCode to Variable:responseCode)
The RequestHeader is set to the requestHeaders variable though the web service call properties
then Log Variable:responseCode to the workflow history list
After manually running the workflow in SharePoint on a list item in the ISR Approvers list it Logs "Unauthorized" in the Workflow History Log. It does this with every SharePoint REST web service call that I have tried through the workflow.
It doesn't have anything to do with the Workflow Manger being installed on the same machine as the SharePoint WFE does it?
Thank You for any insight

Hi,
According to your post, my understanding is that you had 401 Unauthorized Error when calling a SharePoint REST web service from SharePoint 2013 Workflow.
Please make sure you use the ‘Call HTTP Web Service’ correctly.
You can enter the URL into the brower to check whether it is correctly.
You need to
create the Request header requestHeaders
using a Dictionary:
Accept : application/json;odata=verbose
Content-Type : application/json;odata=verbose
To associate the
requestHeaders variable, select the Call action
property, set the RequestHeaders property to
requestHeaders.
Please refer to the following articles:
Working with Web Services in SharePoint 2013 Workflows using SharePoint Designer 2013
Calling the SharePoint 2013 Rest API from a SharePoint Designer
Workflow
In addtion, you need to make sure you install the workflow manager correctly.

Issue with Calling Rest Web Service using Designer workflow

Hello all
I am calling a Rest web service- HTTP Post (yammer API)-
http://www.yammer.com/api/v1/messages.json?data-app-id=myappid&group_id=groupid&body=MyPost in yammer using sharepoint 2013 designer workflow.(My Requirement is to create a yammer post when I approve an item in sharepoint).
but my header parameters are creating issue while executing workflow.
Currently I have these many parameters configured in request header
Accept -application/json; odata=verbose
Content Type -application/json; odata=verbose
content length header -255
Is there anything wrong or I need to additionally pass some values in call web service action?
Any help would be highly appreciated

Hi Mahesh,

Is it possible to add a user using the RESTful Web Services SDK

Others have asked before about user management features in the RESTful Web Services SDK. However I can find no answers or links which provide an answer to the question 'Is it possible to add a user using the BI 4.1 SP2 RESTful Web Services SDK'?
Any help would be appreciated.
Regards,
Steve

Hi Steve
Unfortunately, not possible. The BI RESTful can only get "stuff" that is already there. I suppose this would fall under some sort of "Object Creation" API and that is not there. Yet. Rumors abound, but nothing firm. Just as a BTW.; the Business Intelligence platform RESTful Web Service Developer Guide 4.1 is here:

Protecting a REST web service with Policy Agent

I have deployed a REST web service in Glassfish using Jersey Annotations. A UI in the same Glassfish instance is protected by a policy agent that forces users through a login page. I would like to protect the REST web service with BASIC Authentication using the same policy agent. Is this possible? Is there supporting documentation?

Hi Daniel,
When you publish a message through Rest, hope your Restful service will receive/process the posted message?
So
YourBizTalk -->(Post Message to)-->RestFulService
From the error message, "the published message could not be routed because no subscribers were found.", it seems like the this Restful service is a
wrapper (or service interface) for BizTalk at client end( where message has been posted thru Rest) and actual posted message is “processed” by BizTalk and the error "" is from BizTalk "after" Rest. This message says the message you posted
through rest is not found subscription at their end.
So
YourBizTalk -->(Post Message to)-->RestFulService -->Clients'BizTalk.
Here problem is at Clients'BizTalk as shown where the posted message to their BizTalk is not processed because no subscription has been found.
If this answers your question please mark it accordingly. If this post is helpful, please vote as helpful by clicking the upward arrow mark next to my reply.

URGENT: Rest web service with get method works fine in browser but not with java client(Android)

Hi ,
I have created one REST web service which accepts two parameters send back JSON results.
I tested the it in browser with URL as http://+Inteernal server+/ords/utimes/login_info?p1=+first_param+&p2=+second_para+
Web service URL : http://+Inteernal server+/ords/utimes/login_info?p1={p1}&p2={p2}
But when java team wants to access it from java code it gives error as "400- Bad Request".
one more IMP thing : when I test it in RESTful web service by using "set bind variable" , it only set value of first parameter.
APEX version : 4.2
Database : 11g (XE)
ords : 2.0.8
please help me ASAP.

Calling a restful web service from a script task

Hi. I'm weak in c# but am looking to accomplish this...
I want to call a RESTful web service from an ssis script task. I don't want to create a web service so I'm hoping there is some publicly available one I can practice with before our web team provides me with the service I'll eventually use. Can
the community provide an example? I wish I had more but my knowledge is very limited except for using ssis in more sql centric apps. It would be great if I could exercise both a get and put verb but I understand i'll be lucky if I can even get
a get to work.
Here is an example of a get I found on the web but I don't know if its a viable candidate for me to practice with from my package...
using System;
using System.IO;
using System.Net;
using System.Text;
// Create the web request
HttpWebRequest request = WebRequest.Create("http://developer.yahoo.com/") as HttpWebRequest;
// Get response
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
// Get the response stream
StreamReader reader = new StreamReader(response.GetResponseStream());
// Console application output
Console.WriteLine(reader.ReadToEnd());
and in the same article an example of a put ...
// We use the HttpUtility class from the System.Web namespace
using System.Web;
Uri address = new Uri("http://api.search.yahoo.com/ContentAnalysisService/V1/termExtraction");
// Create the web request
HttpWebRequest request = WebRequest.Create(address) as HttpWebRequest;
// Set type to POST
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
// Create the data we want to send
string appId = "YahooDemo";
string context = "Italian sculptors and painters of the renaissance"
+ "favored the Virgin Mary for inspiration";
string query = "madonna";
StringBuilder data = new StringBuilder();
data.Append("appid=" + HttpUtility.UrlEncode(appId));
data.Append("&context=" + HttpUtility.UrlEncode(context));
data.Append("&query=" + HttpUtility.UrlEncode(query));
// Create a byte array of the data we want to send
byte[] byteData = UTF8Encoding.UTF8.GetBytes(data.ToString());
// Set the content length in the request headers
request.ContentLength = byteData.Length;
// Write data
using (Stream postStream = request.GetRequestStream())
postStream.Write(byteData, 0, byteData.Length);
// Get response
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
// Get the response stream
StreamReader reader = new StreamReader(response.GetResponseStream());
// Console application output
Console.WriteLine(reader.ReadToEnd());

Hi
db042190,
These kinds of operations are commonly found outside the SSIS section of the forum, you just need to "borrow" the code and wrap into the Script Task. And based on what you see you are on the right tracks.
One thing you need to be aware of: in production such RESTfull call usually lead to a fiasco for the machine residing in some kind of DMZ or Firewall rules prohibiting these methods or you need a proxy account to run the package and you face unbeggable admins
who resist to relaxing security.
My suggestion is to go the easy route: write the app up as a console, standalone app - it will be easier to debug and there will be complete examples of them in abundance on the web.

Consuming RESTful web service in Apex app

Hi,
I have created a RESTful Web service through an Apex application (4.0) and published as a public web service. Can someone point me to an example of how to then consume that service in another Apex app? The output is straightforward XML that I can retrieve just by pointing the browser to the URL of the service created, but when I go to create the REST Web Reference for the receiving application, I am not sure what to put for the Response Xpath or Response Namespace. The service is meant to just return report records that were created in the REStful Web service with no input required.
The service XML looks like this:
<ROWSET>
<ROW>
<PROJ_ID>132</PROJ_ID>
<PSL_NETID>xxxxxxxx</PSL_NETID>
<PROJECT_TITLE>11g- Oracle Upgrade to RAC 11g</PROJECT_TITLE>
<CUSTOMER>OIT</CUSTOMER>
<DIVISION>EIS</DIVISION>
</ROW>
<ROW>
<PROJ_ID>132</PROJ_ID>
<PSL_NETID>xxxxxx</PSL_NETID>
<PROJECT_TITLE>11g- Oracle Upgrade to RAC 11g</PROJECT_TITLE>
<CUSTOMER>OIT</CUSTOMER>
<DIVISION>CSS</DIVISION>
Any help would be appreciated.
Thanks,
Pat

Hi,
I have made progress in this. I created the RESTful report service in an Apex 4.1 application. (previous attempt was with 4.0 version of Apex)
I then created a separate application and created a RESTful web service reference that I tested and it was successful in bringing up XML. However in Apex 4.1, when I create a report following the Wizard for creating a report based on that Web service reference I get the error: ORA-31013: Invalid XPATH expression Which I don't know how to get past. The Xpath provided in the Web service reference test gave output below and brought back a result. There was no where during the Report creation to provide an Xpath. Am I missing something or is 4.1 not quite Web service ready??
This is what I get from the test of the Web service reference in the Apex App from which I want to create a report: (I see in this XML the data I was expecting from the test of the RESTful web service but it looks like the output I get from the Web service test is more like the Report xml itself.)

How to build complex object to be sent to a RESTful web service?

Hi,
I'm working with RESTful web services on J2EE 1.6.
I create the database, generate the entities and generate the web services.
I must implement Javascript clients and I don't want to use any open source for that.
I have a simple example that works just fine. For the database :
CREATE TABLE Shopper(
shopperId MEDIUMINT AUTO_INCREMENT PRIMARY KEY,
firstName VARCHAR(40),
lastName VARCHAR(40),
phone VARCHAR(40),
email VARCHAR(50) NOT NULL,
receiveEmailNotification ENUM('Y', 'N'),
index(email)
I create this xml information with javascript :
*<shopper>*
*<email>c</email>*
*<firstName>c</firstName>*
*<lastName>c</lastName>*
*<phone>c</phone>*
*<receiveEmailNotification>Y</receiveEmailNotification>*
*</shopper>*
and it is saved in the database. I have a more complex application with relationships between entites. For this database :
CREATE TABLE Shopper(
shopperId MEDIUMINT AUTO_INCREMENT PRIMARY KEY,
firstName VARCHAR(40),
lastName VARCHAR(40),
phone VARCHAR(40),
email VARCHAR(50) NOT NULL,
receiveEmailNotification ENUM('Y', 'N'),
index(email)
CREATE TABLE Address(
addressId MEDIUMINT AUTO_INCREMENT PRIMARY KEY,
street VARCHAR(60),
streetNo VARCHAR(20),
postalCode VARCHAR(30),
city VARCHAR(40),
country VARCHAR(40),
otherInfo TEXT,
shopperId MEDIUMINT NOT NULL,
foreign key (shopperId) REFERENCES shopper(shopperId) ON DELETE CASCADE,
index(shopperId)
I was expecting that xml information sent from the browser should be:
*<address>*
*<city>c</city>*
*<country>c</country>*
*<otherInfo>c</otherInfo>*
*<postalCode>c</postalCode>*
*<street>c</street>*
*<streetNo>c</streetNo>*
*<shopper>*
*<email>c</email>*
*<firstName>c</firstName>*
*<lastName>c</lastName>*
*<phone>c</phone>*
*<receiveEmailNotification>Y</receiveEmailNotification>*
*</shopper>*
*</address>*
but I keep on getting errors.
I want to send one XML structure that will be stored in two tables according to the foreign key relation.
Does the RESTful web services code generated by Netbeans or Eclipse support this?
Is my XML structure not built correctly?

Kevin,
My object base class is Abstract and class I am using in Flex 3 is class inheriting abstract class. But when calling webservice Flex creating soap message of base class and I am getting error in .Net web services that "Can not create instance of Abstract class".
Below is the soap message difference calling same WCF method from .Net and Flex. For example Constraint is the base class and JobConstraint is the class which inherit Constraint class. But flex send message forming only Constraint while .Net soap is specifying i:type="JobConstraint".
Part of soap message Calling from .Net
<
Constraints><
Constraint i:type="JobConstraint"><Position
>true</Position><
Rank>2</Rank><
Requirement>true</Requirement></
Constraint></
Constraints>
Part of Soap message calling from Flex 3
<ns0:Constraints>
<ns0:Constraint>
<ns0:Position>true</ns0:Position>
<ns0:Rank>2</ns0:Rank>
<ns0:Requirement>true</ns0:Requirement>
</ns0:Constraint>
</ns0:Constraints>

REST web-service invocation gives error ORA-29266: end-of-body reached

We are trying to consume a REST web-service. We send county code and country name to the WS, it then inserts the data and sends us a response in XML.
I used this PL/SQL code to invoke the rest WS.
http://blog.warp11.nl/2011/07/calling-a-rest-webservice-with-plsql/
Problem is there is an error ORA-29266, when processing the utl_http.read_text(t_http_resp, t_respond);
The error means that there is no response. i.e. NULL response.
We can PING the service the WS is, so we are not using authentication. Could this be the problem?
Any help could be greatly appreciated.
