Can universe connect to restful web service which is not soap based

Can universe connect to restful webservice? I know it is allowed to connect to SOAP webservice. Currently is using WSDL1.1.
How about restful web service which does not have any wsdl file?

Hi,
there is a chapter - Security Configuration at Message Level
in XI config guide which specifies everything you need - this is what you need
so I hope no further explanations are necessary

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

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

Connect to Secure web service with certificate from SAP EP

Hi Experts,
Here is the current situation:
1. Our business requirement is to connect 3rd party RESTful web service which requires secure connection with private client certificate attached
2. I've tested in my Java test application and successfully attached private certificate to HttpsURLConection request to the web service and made a connection. No problem at all.
KeyStore keyStore = KeyStore.getInstance("PKCS12");
InputStream inputStream = new FileInputStream("privateKeyCert.p12");
keyStore.load(inputStream, "myPassword".toCharArray());
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
keyManagerFactory.init(keyStore, "myPassword".toCharArray());
KeyManager[] kms = keyManagerFactory.getKeyManagers();
SSLContext sslContext = SSLContext.getInstance("SSL");
sslContext.init(kms, null, new SecureRandom());
SSLSocketFactory sockFact = sslContext.getSocketFactory();
URL url = new URL("https://www.thirdpartywebservice.com/testroot/");
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setSSLSocketFactory(sockFact);
conn.setRequestMethod("POST");
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
conn.setDefaultUseCaches (false);
conn.setRequestProperty("Content-Type", "text/xml");
3. Next, I tried to apply my Java application to SAP EP NetWeaver, and found that I have to use SecureConnectionFactory:
https://help.sap.com/saphelp_nw70ehp1/helpdata/en/e2/71c83edf72e16be10000000a114084/content.htm
4. So, I modified my Java code for SAP EP:
KeyStore keyStore = KeyStore.getInstance("PKCS12");
InputStream inputStream = this.getClass().getClassLoader().getResourceAsStream("privateKeyCert.p12");
keyStore.load(inputStream, "myPassword".toCharArray());
SecureConnectionFactory scFactory = new SecureConnectionFactory(keyStore);
HttpURLConnection conn = scFactory.createURLConnection("https://www.thirdpartywebservice.com/testroot/");
conn.setRequestMethod("POST");
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setUseCaches(false);
conn.setDefaultUseCaches (false);
conn.setRequestProperty("Content-Type", "text/xml");
And I'm facing the following error message:
Exception: java.security.UnrecoverableKeyException: ja
va.security.GeneralSecurityException: Unable to decrypt private key: javax.crypto.BadPaddingException: Invalid PKCS#5 padding length: 253
Could you please help me what this error message means?
Do you think do I need to to do some other configuration to make connection to web service with client certificate?
This is our first approach. Please help...
Thank you in advance.

SunJSSE implement SSL server CertificateRequest in a strict mode, if client failed to find a proper certificate corresponding the server request, it does not guess what's the proper certificate and send to the server. In your case, because there is no intermediate certificate in the client context, so there is no way to make the decision which certificate would be acceptable by server, so client does not send any cert to server. That's why you got a handshaking error.
I guess your client key store does not contains a full certificate path from the client end-entity certificate to the root CA. Please import the full certificate path into the key store.
BTW, these approaches should work, but I found no reason why one does not adopt #1:
1. import the full certification path of client certificate into client key store.
2. as a workaround, configure the server to send a list including the intermediate certificates;
3. as a workaround, you will have to customize the client KeyManager if you don't want to or are not able to configure the server to send a list including the intermediate certificates.

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

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.

Refreshing a document with Restful Web Services

Hello,
I want to refresh a document with Restful Web Services. The document is based on a BEx query with a date variable, which is set as a prompt.
In order to refresh I send a PUT request like:
PUT <webiURL>/documents/{documentId}/parameters
and add the parameter, which is the prompt variable, to the body:
{"parameters":{"parameter":[{"id":0,"answer":{"@type":"Date","values":{"value":"2014-07-01T00:00:00.000+00:00"}}}]}}
Then I get a result like:
{"success":{"message":"The resource of type 'Document' with identifier '1234' has been successfully updated.","id":1234}}
Now I assume that the document is refreshed. However if I now read the properties with:
GET <webiURL>/documents/{documentId}/properties
the lastrefreshtime is not changed.
Has anybody an idea what happens during a refresh and what is updated?
Kind regards,
Michael

Hi,
I have analyzed that the refresh seems to be only valid for the current session. This means, if I logon, refresh the document and determine the properties, I get the new refresh time.
However, if I logoff, I still get the old refresh time. So the refresh is lost or only valid for a session.
Is this the default behaviour?
Regards,
Michael

REST Web Service References: Can't run Google APIS

Hello Everyone!
I am learning on how to integrate REST web service reference in APEX application. I found a tutorial video at YouTube on 'Creating and Using a RESTful Web Service in Application Express 4.2', which found to be very helpful and easy to do on my sample app. The REST Web Service URL:
http://maps.googleapis.com/maps/api/geocode/xml?address=san%20fancisco&sensor=false
But my application throws an error as below:
1 error has occurred
ORA-29273: HTTP request failed ORA-06512: at "SYS.UTL_HTTP", line 1130 ORA-24247: network access denied by access control list (ACL)
After going through some of the posts here at OTN, I have granted access as follows:
GRANT EXECUTE ON SYS.UTL_HTTP TO ETI;
GRANT EXECUTE ON SYS.UTL_INADDR TO ETI;
GRANT EXECUTE ON SYS.UTL_TCP TO ETI;
GRANT EXECUTE ON SYS.UTL_SMTP TO ETI;
GRANT EXECUTE ON SYS.UTL_URL to ETI;
GRANT EXECUTE ON SYS.UTL_XML to ETI;
Second thing I did was, created and assigned ACL:
begin
dbms_network_acl_admin.create_acl (
    acl         => 'googleapis.xml',
    description => 'Google Translate API',
    principal   => 'CONNECT',
    is_grant    => true,
    privilege   => 'connect',
    start_date => null,
    end_date    => null
dbms_network_acl_admin.add_privilege (
    acl       => 'googleapis.xml',
    principal => 'CONNECT',
    is_grant => true,
    privilege => 'connect'
dbms_network_acl_admin.assign_acl (
    acl => 'googleapis.xml',
    host => 'ajax.googleapis.com'
dbms_network_acl_admin.assign_acl (
    acl => 'googleapis.xml',
    host => 'maps.googleapis.com'
end;
All these statements were executed on my database with out any error, even though not helping my web service reference to work.
Any idea how can I get my Google API REST Web service working, what is the thing I'm missing here?

I apologize for the lack of information.
I thought I had included a list of schemas for you to try out.
At first, (due to the GRANT ___ TO ETI;) I thought you were writing your own Web Service parser in PL/SQL.
(If that was the case, than ETI would need be part with the ACL)
Then, I realized,you were using the built in APEX functionality.
In this case, try adding your APEX_{version} schema as part of the ACL.
I'm not sure if this will work (I haven't tried it).
However, I do know you need to add the APEX_{version} to the ACL if you use the LDAP Authentication.
finding APEX_{version}
select comp_id, version, status, schema
from dba_registry
where comp_id='APEX'

Can we use REST web service as Data source in SSRS? !!!!NOT SOAP!!!!

Hello,
We have requirement to use the REST web service as the Data source of SSRS. Tried with XML as Data Source, but unfortunately I could not succeed because the query expects SOAPAction which is not available in REST Service.
Do we have any option to use REST Service, if so please provide some basic example, so that I can try out some options.
If not, do we have any alternate solutions to handle these situations?
Thanks!
Vinay

Hi Vinay.
After looking on it for some time, I am afraid currently there is no document to talk on how to use the REST web service as a data source.
You can use the link
http://technet.microsoft.com/en-US/library/aa964129(v=SQL.90).aspx for a renference.
From a support perspective currently this is really beyond what we can do here in the forums. If you cannot determine your answer here or on your own, consider opening a

Laserjet Pro 400 MFP M425DN Can not connect to HP Web Services

I have a Laserjet Pro 400 MFP M425DN printer on a network running windows 7 and we Can not connect to HP Web Services. When we use the display on the menu it comes back with error "Internal Processing error, try again or check firmware update" We installed the new firmware but still get the same message. IF type in our printers IP address into our browser we get the info on our printer but if we go to the HP web services tap and click enable it trys but come back with a "connection error"
Any ideas?
Thanks
Paul

I just updated my Firmware on this printer today to the latest version dated May 3 2013 and Web Services
worked. Had the same type of problem you had for months and had worked with HP but could never get
Web Services to work at my location with my Modem/Router.
Had tried at other locations and it would work with the old Firmware. But for some reason it did not at my
location with the Modem/Router I was using.
Again the latest Firmware fixed it. I tried all the other solutions that I had found on the internet and non of them worked.

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).

JSP page communicating with a MySQL db throw a Glassfih RESTful web service

Hello;
I am en newbie in servlet/JSP stuffs, and as I said in the subject, i'm looking for the best way to make my JSP pages communicate with my db. My application already consists in a RESTful web service that, just for the record, communicates with a JavaFX Client.
(>What i'm looking for is to write datas in my database through this JavaFX client, and it seems like this can only works by passing through a intermediate scripting language like JSP).
To get back on my issue, I don't really know about JSP. I read many tutorials but it still seems confusing to me. Can somebody show me, by a detailed example, how I can do that ? (Preferably by using jsp beans like "usebean", that i find very useful).
Thanks a lot.

don't make your JSP 'communicate' with a database. These tasks are for servlets and specific business logic classes which you can use in your servlets.
To connect to a database, use the JDBC API. Plenty of tutorials about that around the net.
I don't really know about JSPYeah well, you already identified your problem then. The solution is very simple: learn. To be able to learn, get a good resource, such as a book and not some vague tutorials that you find on the net. For example, I always recommend this free online book:

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.

InfoPath 2010 and REST web services, custom code button firing twice and second click fires error

Hi,
I have two supposing simple issues which I'm having problems correcting.
If a add a button to the form and write some custom code (See below) to submit some data via a REST Web Service data connection. The code runs but somehow fires the URL twice to the web service.
I've also recreated similar functionality using Rules on a button and some concat formulas and exactly the same thing happens when I the run the data using the Query Data Action, it fires the URL twice at the web service.
How can I stop this.
Secondly, if I use the custom code route, it work correctly the first time it pressed except for the double fire issue, but the second time I click the button the InfoPath internal system throws up an issue. See screen shot below.
Any help would be appreciated.

Report Repointing using RESTful Web Services

With respect to this link: Changing Dataproviders for a Webi Report using RESTful Web Services
Cosider the following scenario:
You have an automation code using which, you accepts 20 report id and their respective Current universe id and New universe id.
If suppose, you have user input prompts in 10 reports and you don't know those 10 reports, how will you provide values to those prompts at a single execution of the code?
OR
Is there any function using which you can provide associated random value to those prompts?

Hi Raghunath,
Looking at your macro, most of the functionality would be available with REST SDK. With BI 4.x REST is now only SDK which provides APIs to work with webi report. With .NET or Java SDK we could not eeven schedule a webi doc with prompts.
With BI 4.1 REST APIs include.
refresh report, schedule report, save report, export which is done by your macro.
For detailed tasks, such as saving and modifying the report for specific users and send to schedule, you would need to play around with REST Urls to understand the workflow.
For starters take a look at the devleopers guide for REST here:
http://help.sap.com/businessobject/product_guides/sbo41/en/sbo41_webi_restful_ws_en.pdf
Here is the doc which compares the availability of SDK APIs with different BI versions.
http://scn.sap.com/docs/DOC-53285
For any Enterprise level tasks, you could always use .NET or Java enterprise SDk and comibe it with your REST app.
