Creating a REST Web Service

I give up. I have searched the forums and Internet and read dozens of articles and watched videos but I still cannot get my web service working. My agency has an oracle db that I can pull data from it using REST. This URL http://iaspub.epa.gov/enviro/efservice/tri_facility/state_abbr/TX/facility_name/CONTAINING/EXXON will return an
XML of 15 Records in a web browser. When I set up the REST service I either get 3000 records or a 400 error or a couple of other messages (I check this by using the debug). I followed a video step by step and I keep getting an error. I tried &FACILITY_NAME (error) ?FACILITY_NAME (3000+records) I just can't figure out what I am doing wrong. Anyone have any ideas? The Oracle, APEX and Application Express was installed by others. As far as I know it was installed correctly. Also if I put the whole URL from the browser I get the records. Below is the web service:
Edit REST Web Reference
*Name: FRS_NAME
* URL: http://iaspub.epa.gov/enviro/efservice/tri_facility/state_abbr/TX/facility_name/CONTAINING/?FACILITY_NAME

Thanks in advance for any assistance,

Hi Amey,
I came across this link from google.
Put SOAP to REST using CE
As Anthony suggested this is not the right discussion forum.

Creating the REST web service

This question was posted in response to the following article: http://help.adobe.com/en_US/ColdFusion/10.0/Developing/WSe61e35da8d318518-5719eac51353e6bb 244-7ffd.html

The narrative says "specify EITHER of the following in the tag cfcomponent: restPath or rest", but the example speficies both of them. "Either" implies "one or the other, but not both", which contradicts the example. Which is it?
Also the CFML is poor. The variable name is bad, and it should be VARed.

Create RESTful web service with CSV format (bug??)

Hi All:
I am using APEX 4.2.2 with APEX listener 2.0.2.
I have create a RESTful web service to retreieve some data from a table. The format is "CSV" (the other option is JSON, which I am not faimilar with).
then I tested and it generate with below sample data.
United States,"Zhang, Kevin",IT
Above data means: Country, fullname, department
As you can see value of fullname is double-quoted and also contains a comma (,) in it.
Then I create a web service reference in a test application. Then I create a a form and report on web service.
The problem is the fullname. The output looks like below:
Country fullname Department
United States "Zhang IT
As you can see, APEX is not able to get fullname correctly.
Anyone see this issue and how to resolve it?
Thanks!
Kevin

Kevin,
I'm not sure I would classify it as a bug so much as an enhancement. We need the ability to set the "Text qualifier" as one can from Excel. This would allow the above to be seen a single a single field and, then, to do what you want. However, as I'm sure you realize, this just doesn't exist at the moment.
So; you could store the first and last names in separate fields in the table (don't forget that you could use virtual columns for this purpose) or simply alter your query to pull them out as if they were separate fields, i.e. use SubStr and InStr.
If you simply must see them in this format when the CSV is opened, you could create a formula in Excel to do this for you.

Creating RESTful Web Service for BLOB retrieval

Hi,
Just got RESTful web services working in Apex 4.2.1 with new Listener 2.1.
I have now been asked to create a RESTful web service by which photos in BLOB column can be retrieved upon providing the ID for that photo. Can this be done using the Creating RESTful Service Module of Apex 4.2.1? Looking at the Apex 4.2 documentation, I would assume this can be done, but has anyone used this with BLOB data?
Thanks,
Pat

Hi Pat,
Yes this can be done using RESTful Services - you just need to ensure the query used is in the required format. To obtain a BLOB for a given ID, you would need create a Resource template and handler with the following settings:
Resource Template Settings:
URI template: emppic/{id}
Resource Handler Settings:
Source query: select mimetype, product_image from demo_product_info where product_id = :id..where the format of the SQL query is SELECT 'content_type', blob_column FROM . . ., as mentioned in Rick Greenwald's Cloud White paper "RESTful Web Services for the Oracle Database Cloud", under the "SQL Source Type" section (see www.oracle.com/technetwork/database/database-cloud/public/restful-wp-1844130.pdf ):
where 'content_type' is a string passed to the browser to be used to identify the incoming data, and the column to identify the source of the data being sent back. This data is sent back untouched by the Oracle Database Cloud Service. The Media Resource Source Type is typically used for media objects, such as images, where the data will be directly handled by the recipient making the call.The MIMETYPE column in the sample query above holds the necessary setting for the 'content_type' i.e. 'image/jpeg'. The value of ID is then passed in as a parameter when calling the service e.g. emppic/1234. The item level help text would be more helpful if it included additional information, and this is something we intend on addressing in a future release.
I hope this example helps.

Hilary

Which is the best API for creating restful web services.

Hi guys,
I have tried a lot of apis to create a restful web service. But none of them has perfect documentation or examples. Which is the best one that has good support and future.

"Best" automatically implies opinions and speculation; one I personally believe has a bright future is Jersey. Jersey is the reference implementation (RI) for [JSR-311|http://jcp.org/en/jsr/detail?id=311] ("The Java API for RESTful Web Services" or JAX-RS).

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.

Hi Pragya,
thank you for the update.
Another question: could you please give us any reference about these corrections you told about? Maybe they could be relevant in our case too.

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.)

REST Web Service Output Parameter not working in POST Handler

I've created a RESTful Web Service in Oracle Apex, using a POST method as "handler". I've setup 11 input parameters which all work fine, it is my one output parameter that does not return successfully.
Here is detail on the Output Paramter
Name: returns
Bind Variable Name: :returns
Access Method: OUT
Source Type: Response
Parameter Type: String
The actual source is a call to a pl/sql package that returns a value that I set :returns equal to (eg :returns := v_result). I've tried this with Source Type Header and still the same result, 'no output'.
I see APEX is calling wwv_flow_api.create_restful_param to generate the parameters (for importing), is there any documentation on this procedure?
How can I get this output parameter to return something in the response?
The request accepts a Json payload.
Any help greatly appreciated
Thanks,
James

Solved my own problem :returns does not work needs to be returns
Does Not Work
Name: returns

Exposing a report as RESTful web service - Parameters

Hi,
I am creating a RESTful web service by exposing an apex report. It just works fine and it renders the data. However I want to have parameters and values in the web service URL so that the data can be filtered based on the parameter values?
For example:
http://127.0.0.1:8080/apex/apex_rest.getReport?app=100&page=15&reportid=rest_example renders correctly for the report query
select * from (
select
"CUSTOMER_ID",
"CUST_FIRST_NAME",
"CUST_LAST_NAME",
"CUST_STREET_ADDRESS1",
"CUST_STREET_ADDRESS2",
"CUST_CITY",
"CUST_STATE",
"CUST_POSTAL_CODE",
"PHONE_NUMBER1",
"PHONE_NUMBER2",
"CREDIT_LIMIT",
"CUST_EMAIL"
from #OWNER#.DEMO_CUSTOMERS )
where (
instr(upper("CUST_FIRST_NAME"),upper(nvl(:P15_REPORT_SEARCH,"CUST_FIRST_NAME"))) > 0 or
instr(upper("CUST_LAST_NAME"),upper(nvl(:P15_REPORT_SEARCH,"CUST_LAST_NAME"))) > 0
)But I want to filter the result for a particular customer id by getting a value in the URL like this.
http://127.0.0.1:8080/apex/apex_rest.getReport?app=100&page=15&reportid=rest_example&P15_CUSTOMER_ID=6 and to use the value received thro the URL in the report query
select * from (
select
"CUSTOMER_ID",
"CUST_FIRST_NAME",
"CUST_LAST_NAME",
"CUST_STREET_ADDRESS1",
"CUST_STREET_ADDRESS2",
"CUST_CITY",
"CUST_STATE",
"CUST_POSTAL_CODE",
"PHONE_NUMBER1",
"PHONE_NUMBER2",
"CREDIT_LIMIT",
"CUST_EMAIL"
from #OWNER#.DEMO_CUSTOMERS
where customer_id = :P15_CUSTOMER_ID)
where (
instr(upper("CUST_FIRST_NAME"),upper(nvl(:P15_REPORT_SEARCH,"CUST_FIRST_NAME"))) > 0 or
instr(upper("CUST_LAST_NAME"),upper(nvl(:P15_REPORT_SEARCH,"CUST_LAST_NAME"))) > 0
)Is it possible to have it working in this way?
I am currently testing this in apex 4.2 and Oracle 11g XE. My development environment will be Apex 4.1 and Oracle 11g.
Thanks in Advance.
Regards,
Natarajan
Edited by: Nattu on Dec 18, 2012 2:09 AM

It does accept values for the parameters but does not accept value names in the URL.
The previous thread Restful web service passing character parameters helped me to get it working.
Thanks.

Get the client (caller) IP in a RESTFul web service resource

Hello,
How i can get the client (caller) IP inside a RESTFul web service resource?
Something like for SOAP Web Services
          MessageContext msgCtxt = wsCtxt.getMessageContext();
          HttpServletRequest req = (HttpServletRequest) msgCtxt.get(MessageContext.SERVLET_REQUEST);
          String clientIP = req.getRemoteAddr();
Thank You

Thin-client uses a RESTful Web Service

Hello everyone!
Once I've develop a few web services, it's time to "consume" them. I'm trying to develop a thin-client in JAVA (with the netbeans ide) but I haven't found the best way to do it.
So, which is the best way to create a LabVIEW RESTful webservice?
Obviously, JAVA is an option, how about create a client with another VI?
Greetings!

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:

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();

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.

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>
