Unable to call REST webservice

Hi all,
I'm trying to create a REST web service reference in Apex 4.1 (as a demo only). It's a call to http://graphical.weather.gov/xml/sample_products/browser_interface/ndfdXMLclient.php with 5 input parameters.
When I test the web service in Apex Builder, I receive an error from the proxy server:
Error Code: 403 Forbidden. The ISA Server denied the specified Uniform Resource Locator (URL). (12202)
However, I can call the same web service from the database via pl/sql. This works, running in the parsing schema (I can't test it from the apex_040100 schema):
declare
v_result clob;
begin
v_result := apex_web_service.make_rest_request(
    p_url            => 'http://graphical.weather.gov/xml/sample_products/browser_interface/ndfdXMLclient.php'
   ,p_http_method    => 'GET'
   ,p_parm_name => apex_util.string_to_table('lat:lon:product:maxt:mint')
   ,p_parm_value => apex_util.string_to_table('39:-77:glance:maxt:mint')
dbms_output.put_line(v_result);
end;I don't understand this difference. Any idea what the difference is between the two? I can only explain it if the source from these two calls is different. One source is blocked by the proxy, the other is not.
Thx,
Ino
Never mind. Although I checked it before, I thought: let me check one more time if the application has an incorrect proxy property. It did .....

Always check the access_log and error_log files of the Apache web server in such a case. This will identify whether the error comes from Apache itself, mod_plsql, the Apex run-time engine, or the Oracle database.
I see that you're creating a HTTP/1.1 in PL/SQL - however, the web server response indicates a HTTP/1.0 call was received. Unusual. And could be part of the problem.

Calling REStful webservices from Designer

Hello,
I know we can connect to a webservice via wsdl type data connection, but has anyone tried calling Restful web service by any chance?
If so please let me know how can we do that.
Thanks
Manoj

Hi Paul,
Are RESTful services supported in the newest version of LiveCycle? If so can you provide a short example? Thank you,

InfoPath unable to call OOTB webservices in a SAML claims web application

We have InfoPath Path forms with Nintex workflows that we are planning to move to SharePoint 2013. The SharePoint 2013 web app is using SAML claims , ping federate is the identity provider.
We are unable to make a call from InfoPath to the OOTB webservices. We tried using the Secure store and UDCX file but that also does not seem to work with SAML based claims. Has anyone come across this scenario who can suggest an alternate solution?

Hi Supriya,
From the link below, InfoPath forms service does not work with SAML authentication.
Features that do not work with forms-based authentication or SAML security tokens:
http://technet.microsoft.com/en-us/library/hh706161(v=office.14).aspx
There is no dedicated clarify for SharePoint 2013. However, I found some threads that also reports that InfoPath form won't work with claim-based except NTLM claim, such as:

Calling a webservice from weblogic EJB Application

Hello,
I have a webservice running on IIS server. I created a simple java client program to call the webservice and it works fine. However, when I wrapped the same java client program as a EJB Application, I am unable to call the webservice.
I get the following error:
####<Apr 3, 2007 1:59:30 AM CDT> <Info> <WebService> <CASEJBServer> <ExecuteThread: '24' for queue: 'weblogic.kernel.Default'> <<anonymous>> <> <BEA-220094> <An IOException was thrown trying to access the WSDL at the given URL.>
And
"java.io.FileNotFoundException: Response: '401: Unauthorized' for url: XXXXXX"
Could you please give some simple steps as what are the JAR Files required to be included in the Weblogic Server's classpath to call the webservice.
Thanks.

To start off you need to make sure that your client api is in the classpath, either in your ejb or your ear or the server classpath.
The other concern I would have is that it seems you are just not authorized to access the URL.
- Does the WSDL require credentials? So in other words when you go to the URL are you allowed to access the WSDL without athenticating.
- How does your Impl get created?
MyServiceImpl service = new MyServiceImpl()
If you are using the empty constructor then what is the wsdl endpoint in your jar file since that is the wsdl it will use. If the endpoint is localhost/xxx/xxx then you will have issues since that means your not deployed on localhost. What url is at the endpoint? Do you have access to the url from your server?
If you are using "new MyServiceImpl(url);" then again is the wsdl locked down because in this case you will need to do somthing like http://username:[email protected]/xxx?wsdl
Hope this helps.

Making a REST webservice call. Error code: 401 Access to the requested resource is not allowed

Hi All,
I’m having a hard time figuring out how to make Rest WebService calls.
I tried executing this directly through browser and I get an error.
http:localhost:8080/rest/bean/atg/userprofiling/ProfileServices/loginUser?arg1=[email protected]&arg2=Password
13:18:20,613 ERROR [RestSecurityServlet] Error code: 401

at atg.servlet.pipeline.PipelineableServletImpl.service(PipelineableServletImpl.java:267)
From the documentation I understand that I need to create a session, is the session only necessary to access secured components since this
particular method “ProfileServices.loginUser “ has been declared as not secure in restSecurityConfiguration.xml
Also, are there two different ways in which I can log in
1. Using RestSession.createSession providing the username and password.
2. Or using ProfileServices.loginUser or ProfileFormHandler
Can someone please clarify

If you are invoking the REST web-service from a Java client then you can create a RestSession object using the createSession method. But in your case you seem to be invoking it with a HTTP request which by default would be treated as a GET request by ATG's REST implementation. Therefore being a GET, it would try to fetch a property "loginUser" from /atg/userprofiling/ProfileServices component (based on your URL) which would always fail.
To invoke loginUser() method of ProfileServices with your passed argument you need to tell ATG's REST system to treat your incoming request not as GET but as a POST request which you can do using atg-rest-http-method control parameter in your request like this
http:localhost:8080/rest/bean/atg/userprofiling/ProfileServices/loginUser?arg1=[email protected]&arg2=Password&atg-rest-http-method=POST
It should work this way provided your restSecurityConfiguration.xml is proper.

Call secure RestFul WebService with basic authorization via https

Hi,
is there a way to call a secure RestFul WebService with basic authorization via https from APEX?
Database: Oracle 11g XE
APEX: 4.2.1
I have a solution by calling the WebService from Java which was called from the database via scheduled job (execute).
As my hosting partner does not support Java I am looking for another option.
Regards
Markus

Hi,
I think its not possible, in this link you can find in more detail why.
Its related with the use of wallets to acess https requests.
http://www.apexninjas.com/blog/2011/06/https-access-with-utl_http-on-oracle-xe-has-anyone-managed-to-do-this/
Edit: Because you are using Oracle XE

Any pointers why im getting this error.

Hi Ted,
The Java source is in the proxy jar, so you should open it (the proxy jar) with
WinZip, and see what's in the weblogic.jws.proxies.SubmitEFTBillSoap.java and
weblogic.jws.proxies.SubmitEFTBill_Impl.java files.

Error while bringing up ATG REST Webservice

Hi,
I am trying to bring a REST Webservice using ATG 9.3 version.I am getting the below errors in the startup of the instance.I have added "REST" module in the Manifest file and am able to see the entry " C:\ATG\ATG9.3\REST\config\config.jar" in CONFIGPATH(Please let me know if there are other ways to find if the service has come up properly).I am trying to connect to the server using JAVA based REST Client as given below.Also,i have placed the jar files in the CLASSPATH of the module.I am hoping that the webservice have not come up properly because of these startup errors.Please help me out to resolve this issue.

Url service data control - problem while POSTing to a restful webservice

Hi,
I am trying to call a restful webservice to add a new employee .I have created the url service data control. The service method consumes XML.
When i am creating the url service datacontrol I selected the http method as POST and giving the servicepath and servicename as the source. After providing the xsd's path and all , when I test the url connection, I am getting the following error message:
URL Test: Received Error: Method Not Allowed
This might be because the clicking of the test url button is sending the get request, but the actual method is POST.
Now under the data controls navigator, If i view the newly created data control, i could see the loadData(Object) method which i assume is for retrieving the data from the service. But since i have mentioned the method as POST, why such a method is created? Also if its there, can I use the same for insert and update? I have used this loadData (Object) method to create a button which calls the webservice upon click. Under the data control property inspector, i changed the supportsupdate attribute's value to true. But when i am trying to save the employee from the jspx page, I am getting the following message in the integrated weblogic's log
Couldn't get access to the data source. Cause Unsupported Media Type exception in rest service
And on the server side I am getting the following error message:
No message body reader has been found for request class Employee, ContentType application/octet-stream.
I think the request is not going as XML. But while creating the datacontrol i have specified the xsd document for the iput xml request. Does ADF automatically creates the XML from the input parametres? If it does not, then what could be done to achieve that? The default actionListener of the submit button is #{bindings.loadData.execute}. Do i have to override it to send the XML request? Or have I missed anything in trying to achieve what i intend?
I had refered this link for reference :

Hi Frank,
I had specified the HTTP method as POST as well as PUT. But the same error is appearing in the both the cases.
URL Test: Received Error: Method Not Allowed
And when I am clicking on the 'Test URL Connection' , I can't see any option of selecting the HTTP method. This option only appears in the step 2 of creating the URL service data control where we mention the URL endpoint and the source.
What could be the reason for the error.

Unable to call a BPEL Process from ESB

Has anyone worked on Oracle ESB ?
I've implemented an ESB Scenario where, based on some value, either it should call one BPEL process otherwise it should call another BPEL Process. But, Routing Service is unable to call either of the service.
Can anyone help me out?
Thanks in Advance.
Regards

I am able to call the bpel processes from the bpel console. I tried to use the TCP Packet Monitor but it shows waiting for connection and doesn't turn up. I checked the port number. The local server port is correct but I dont know how to check the listener port for it i.e. by default showing 1234.
I tried to test my esb through em as a webservice but it shows the following exception after input:

XML payload in RESTful webservice

Hi all,
Can anyone please suggest on how to call the RESTful webservice (which is used by our client) by passing an XML payload from a PL SQL stored procedure? It is for the authentication purpose. And the username and password has to be passed as the XML payload to the RESTful webservice . Please help, it's a bit urgent.
Thanks in advance

How to set username and password before redirecting to a RESTful webservice

I am a .Net developer who has developed a webservice used by my ColdFusion colleagues. They are using ColdFusion 9 but I'm not sure if they have incorporated any of the newer features of ColdFusion in their apps. Here is a snippet of how they have been invoking the webmethods:
<cfscript>
                     ws = CreateObject("webservice", "#qTrim.webServiceName#");
                     ws.setUsername("#qTrim.trimAcct#");
                     ws.setPassword("#qTrim.trimpwd#");
                     wsString=ws.UploadFileCF("#qTrim.webserviceurl#","#objBinaryData#", "#qFiles.Filename#", "Document", "#MetaData#");
            </cfscript>
As I understand things, the .setUsername and .setPassword correspond to the Windows credentials the CF Admin set when the URL of the .Net webservice was "registered" and given its "name" (for the CreateObject statement above). I have 4 webmethods that are all invoked in this manner and this SOAP protocol works adequately for us. Please note that this ColdFusion web app authenticates anonymous remote internet users by prompting for a username and password and compares them to an application database (i.e. Microsoft calls this "forms authentication"). Because only a few Windows domain accounts are authorized to call this .Net webservice, the above code always uses the same username/password constants and it all works.
My question involves the newest webmethod added to the .Net webservice. It requires that callers must invoke it as a RESTful service which means it must be invoked by its URL. Here is a snippet of C# code that invokes it from an ASP.NET webclient:
            string r = txtRecordNumber.Text;
            string baseurl = "http://localhost/sdkTrimFileServiceASMX/FileService.asmx/DownloadFileCF?";
            StringBuilder url = new StringBuilder(baseurl);
            url.Append("trimURL="); url.Append(txtFakeURLParm.Text);
            url.Append("&");
            url.Append("TrimRecordNumber="); url.Append(txtRecordNumber.Text);
            Response.Redirect(url.ToString());
I assume a ColdFusion script could easily build a full URL as above with appended querystring parameters and redirect. Is there some way for the CF code redirecting to a RESTful webservice (by way of its URL) to set the Username and Password to this Windows account mentioned above? When the DownloadFileCF webmethod is hit it must be with the credentials of this special Windows domain account. Can that be set by ColdFusion someway to mimic the result of the SOAP technique (the first snippet above).
I hope my question is clear and someone can help me make suggestions to my ColdFusion colleagues. Thanks.

Can you clarify what you mean by "establish a different Windows identity"? Usually passing identity to a web site or service means adding something to the request's HTTP headers. This could be a cookie in the case of .NET forms authentication or the "Authorization" header in the case of basic authentication.
The SOAP web service invocation code you posted does use basic authentication, according to the CF docs "ColdFusion inserts the user name/password string in the authorization request header as a base64 binary encoded string, with a colon separating the user name and password. This method of passing the user name/password is compatible with the HTTP basic authentication mechanism used by web servers."
http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec13a13 -7fe0.html
If you need to mimic the SOAP techinque you should have basic authentication enabled for your REST service endpoints.
If your authentication method is different then CF developers will need to add the appropriate HTTP headers to their service calls. Note that calling a REST service from CF would probably be accomplished using the CFHTTP tag if the service is designed to be consumed by the CF server.

How to buid a jar in Jdeveloper, for a class that calls a webservice???
