Consume Restful Web Services

Hi,
I have experience consuming Soap Web Services using utl_dbws.
Our client provides various rest web services that we need to access within the database.
We wan't a pure pl/sql solution without any additional java components.
Does anyone have any information on how to consume REST web services?
Thanks

Check out APEX_WEB_SERVICE.

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.)

Consume JSON rest web services

Hi experts,
I have a requirement to Consume rest web services from a URL, which is in JSON format. Help me out to make it.
Thanks
~Faseeh

Hi Faseeh,
As Anthony has mentioned earlier, you need to specify the accept header as application/json. The Business Intelligence platform RESTful web service SDK also supports providing responses in JSON format. Please refer to the document links which Ludek has pointed out. There are 2 formats which are supported - XML (BIP SDK follows ATOM specification) and JSON.
For eg. for a particular request, below are the responses in 2 formats:
XML format:
<entry xmlns="http://www.w3.org/2005/Atom">
<title type="text">5432</title>
<id>tag:sap.com,2010:bip-rs/AfRWaT5_131NlLLf5bRMLKY/relationships/receivedAlerts/5432</id>
<author>
<name>Administrator</name>
<uri>http://commandcom-lcm:6405/biprws/infostore/12</uri>
</author>
<link href="http://commandcom-lcm:6405/biprws/infostore/5432" rel="related"></link>
<content type="application/xml">
<attrs xmlns="http://www.sap.com/rws/bip">
<attr name="id" type="int32">5432</attr>
<attr name="markedAsRead" type="bool">false</attr>
</attrs>
</content>
</entry>
JSON format:
"related":
"__deferred":
{"uri":"http://commandcom-lcm:6405/biprws/infostore/5432"}
"id":5432,
"markedAsRead":false
Hope this clarifies.

Error when querying REST web services from web-based InfoPath form 2013 environment

The form cannot run specified query, the underlying connection was closed. An expected error occurred
same works in 2010 environment .. are we missing anything in 2013 servers?? please let me know how we can resolve it.. thank you

Need to auto-generate SDK for REST web service.

My company has developed a REST API for some web services, and we'd like to provide users with a Java SDK for consuming those services.
Our services are described by an XSD schema. On the backend, we are using JAXB to create Java classes corresponding to the schema. We create the request objects based on the parameters in the REST url, and JAXB converts our response objects from Java to XML.
We'd like to provide our users with similar Java classes on the client side. They should be able to create the object corresponding to the request, fill in various parameters, and submit it to our web service. The SDK should automatically convert the object into a REST URL, hit the URL with a Get, read the XML response, and convert that response into Java objects.
It seems like we should be able to auto-generate such an SDK based on our schema.
It seems like there are several tools for doing this for SOAP web services. For example, Apache Axis has Java2WSDL and WSDL2Java.
Can anyone recommend tools for creating client-side libraries for consuming RESTful web services? Does anyone have advice on products to avoid?

Replying to my own post here. The WADL2Java project on java.dev seems to be more like what I need. The only user-experience I've seen on the 'net is in this forum post:
http://forum.java.sun.com/thread.jspa?threadID=5239123&tstart=0
Anyone else used it?

How to consume Google REST web service

Dear All,
I have a task to embed Google Maps into web dynpro and/or CRM WebUI.
There is no problem with embedding only map with route on it, but I need also calculated distance.
In WebDynpro I've just created iFrame CHIP component which targets: http://maps.google.pl/maps?output=embed and two CHIPS with import parameters to give source and destination address. Route is calculated and drawn.
Problem is with the distance, because the only way is to consume google web service (which is not SOAP, so I can't use service consumer). It must be something like web request.
URL which I need to access is:
http://maps.googleapis.com/maps/api/distancematrix/xml?&mode=driving&sensor=false&origins=Warsaw&destinations=Hamburg
or
http://maps.googleapis.com/maps/api/distancematrix/json?&mode=driving&sensor=false&origins=Warsaw&destinations=Hamburg
where origins and destinations must be connected with import CHIPS. How to access such service in a proper way?
Second thing is that I have to parse response.. it could be XML or JSON format. I just need summary distance. Any idea?
Btw - I'm quite fresh with WebDynpro and WebUI, so I'm looking for good 'HOW TO' guide. Can you recommend something which is good to start with?
thanks in advance

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.)

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

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.

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.

Java Restful Web service client

Hello,
I need to know a piece of informations:-
requirement is - there will 2 applications, typically, 2 war files - 1 war will be Restful web service producer and 2nd war will be the consumer.
My producer is working fine, so how can I make consumer which will basically call the producer and get the data.
will it be like producer would be a typical jar(in my case war file) file base app which will connect o db and the service related task.
Let me know if there is any better desiging.
Regards,
R

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

1) Are you trying to create a RESTful web service in LabVIEW?
or
2) Are you wondering about creating a thin client to consume the web service?
A1) Web Services in LabVIEW
A2) LabVIEW WebUI Builder You can create a VI to act as a client for your web services, but not a thin client (i.e. running in the browser)

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!

How to call restful web services from BPEL

How do we call create partnerlinks for calling RESTful web services in Oracle BPEL.
Any ideas ?

Raymond,
1. To consume WebService in Flex you don't need FDS at all.
2. AFAIK, you need crossdomain.xml at WS host or System.allowDomain("ws-host") or System.allowInsecureDomain("ws-host") on Flex side. Check Flex documentation.
3. Better to discuss this topic in some other forum -- say WebAS General. It's not related to WD

RESTful Web Services example

Does anyone know of a simple publicly available Restful web service that I can play around with calling from my Apex workspace as a consumer? Something nice and simple (in the spirit of "hello world") such as web service calculator, stock quote, etc..
Also, I was wondering if there is some kind of ability in APEX to import a WADL document, and then APEX can magically create the requests for you?
Thanks in advance!

I was able to resolve the problem -- in the latest version of the RESTful web service that I created, I had left out the creation of the Header Parameter bind variable. Once I did that everything works fine!! I was able to test in the application and got the record of an individual student.
Thanks,
PM
