Native web services in Oracle 11 g

Y at - there no official explanation on how to configure and create native web services to Oracle 11 g and how to properly secure these services? Since Oracle APEX now supports web services use SOAP and REST, it makes sense to have more explanation on creating and securing web services. As know many PL/SQL programmers, it isn't always an easy task to develop web services in jDeveloper to work with databases - with all of these technologies to Add on as jPublisher/Toplink to get the job of things. It is not easy to get the 'How to' guide on creating and securing of the native web services in Oracle 11 g.

Thank you.

Andy

    The SOAP request is not correct.

    So again, it does not solve the problem:

    -Which user you are using to authenticate on the other side?

    If it's another user the owner of the package, then of course you must grant the execute privilege appropriate to this user (and possibly one explicit SELECT on the table referenced too privilege).

  • How to return a multiple registration with Oracle Native Web Service?

    Hi all

    I would like to know the native web service oracle can return multiple records of customer or not?

    I have successfully developed the native oracle web service to return only one record, but the next challenge is to develop the web service to return a multiple record (such as database on each department employees)

    Thank you and best regards,
    Zenoni

    I have successfully developed the native oracle web service to return only one record, but the next challenge is to develop the web service to return a multiple record (such as database on each department employees)

    You may return a list (multiple values/records) in XML (using CLOB or XMLType), CSV or JSON format or whatever.

    function get_employees (p_department_id in number) return clob
as
begin
  return 'your_xml_string_here';
end get_employees;

    It would be up to the customer (the caller of the web service) to extract the values of any format you decide, of course.

  • Native Web Services database: XMLTYPE parameter in PL/SQL with XMLSCHEMA?

    Hello

    I would like to build a function with a parameter of XMLTYPE is the schema of the base, something like this:

    CREATE FUNCTION xy (p_xml XMLTYPE XMLSCHEMA 'http://myschema.com')...

    For now, I do the following code inside:

    l_xml: = p_xml.createSchemaBasedXML ('http://myschema.com');
    l_xml.schemaValidate ();

    / * validate XML with XSD code * /.
    l_nbr: = l_xml.isschemavalidated ();

    Why I want to put the schema directly in the statement is I want to use this function as a Web Service native Oracle. The web service does not know that the structure of the xml parameter because the schema is not known in the statement.

    Thank you and best regards,
    Andreas

    At the present time there is no way for the WSDL generated by the Native Web Services database to incorpirate this information. The problem is that there is no way to associate an XML schema to a variable value, parameter or return of PL/SQL. It should be the work of the XML DB and the PL/SQL to achieve group. It will consider a request for improvement.

    Workarounds only that I can think of would be to have a separate WSDL (made by hand) for this service. Of course, this will have to be to some other URL as expected, so this may not be viable, or to provide your own get (extended) WSDL service as part of the package, which adds the schema information in the WSDL. The Web Service consumer then you have to get the base/orawsv/parcel WSDL? WSDL, then get the WSDL extended by callling the appropriate method on the packaging...

    Hello

    I'm hoping to use the functionality of the native web services on the release of 11g 1 as an easy solution to expose certain procedures. On the test it seems to use SOAP version 1.1 by default, anyone know if it is possible to configure/patch to use version 1.2?

    I hope someone can help...

    Sorry, but for now we are limited to 1.1. What 1.2 features are of interest, given the scope of the current application

    The host name, I put here can be visit through my browser. I think that it is not question of the host server... So, it could be a firewall on my side of the database which must be opened in order to visit the host?

    The "web browser" (your PL/SQL using UTL_HTTP code) code is running on the Oracle database server. He needs the same type of network access that has your browser on your PC. (firewalls open, authentication of the proxy if necessary, etc.).

    On 11g. Not on 10g.

    I saw the code example you post from the link you provided... those who only works on 11 g?
    If we can work on 10g, which package or what are the steps I need to follow in order to have that works on me?

    The code I posted works on both versions. My comment was regards the ACLs. No ACLs exist on 10g. If you only need to execute privs on the affected packages (e.g., UTL_HTTP, etc.).

    ACL were introduced with 11g - 11g, you also need the ADMINISTRATOR to create an ACL for you which will allow access to the UTL_HTTP network so now.

    I try to call the AAU Web Service (CheckIn.wsdl) using oracle.

    Someone has an idea to pass the name of user and password based on the oracle.

    My Code: -.

    Whenever I'm running using
    SELECT the checkin ('WEBSERVICE009', 'WEBSERVICE009', 'Document','weblogic','Private','IT/EBA/Distributor_testuser','D:/ucmfiles/test_WebService_11.txt') FROM dual;

    He expects the name of user and password...

    Anyone with an idea.

    If you use apex, you have access to the wwv_flow_web_services package that has all the procs, you need to do this work. Otherwise, you can use flex_ws_api, which, although a bit outdated, should always work. This can be found at: http://jastraub.blogspot.com/2009/11/flexwsapi-no-on-samplecodeoraclecom.html

    I hope that will get you the start you need. Don't forget soapUI. This has proved to be very useful for my development just to prove that something works. It becomes a very simple way, when I often hear, "UCM does not work... '. ».

  • Integration of Web services in Oracle e-Business 11g1.1.14 JDev

    Hello

    Could someone please help me out with the technique suitable in this regard...

    I created a JDeveloper ADF application which deploys currently use / consume web services from one of my instances of Oracle e-Business. I have outlined some by the filing of the integration of the API and you can see in JDEV.

    To create the web service (via the Wizard), I entered an address for the WSDL file. However, this address is specific to the instance of the application.

    When I migrate / deploy my application in other environments, for example from Dev to Test, I'm sure that the Web Service will always be to 'point' to my instance of development about 99.9%.

    Is the best practice for editing each WebService as I migrate through environments? Or is this now touch on the field of areas outside the scope of this forumn?

    Once again, looking for tips / directions not a complete solution... happy to do my own research it myself.

    Thanks in advance if anyone can help.

    See you soon,.

  • PL/SQL proc as a web service

    Oracle 11.2.0.x
    Reference: Accessing PL/SQL procedures stored using a Web Service (< i > Oracle Developer of Microsoft® XML DB Guide < /i >).

    The feature works very well. Have tested a number of written PL/SQL procs customized this way - is used as a web service and SoapUI and UTL_HTTP procedures as customers, call the web service.

    Issue.
    Can it withstand WSS (Web Services Security) with this feature?

    I added a WSSE to the header of the SOAP envelope when calling - using the standard password (no digest) and the default address. Orawsv XDB servlet accepts the call, the analysis of the SOAP envelope and executes the PL/SQL procedure successfully.

    However, it uses Basic authentication (schema name and password). Not the WSSE.

    Because the WSSE authentication data are part of the SOAP header (and not the body envelope), the PL/SQL procedure of course don't don't can't see the details of the WSSE. (also would make sense ito how XDB abstracts orawsv as a web service interface and allows procedures PL/SQL standard vanilla and functions to be used as web service endpoints).

    So if the WSSE must be supported, this would probably mean that he needs to be supported in XDB himself. And it is outside my small area of expertise of the Oracle.

    Not much on the net (many UTL_DBWS) and just a couple of basic orawsv supports Metalink notes.

    Ideas, suggestions or pointers will be appreciated.

    Thank you.

    WSS will not be supported by Native Web Services database. It is a deliberate choice to differentiate when an application server should be used Vs when DBNWS is appropriate. If you are in an environment where WSS is a requirement, you should be usiing an applications, such as Oracle WebLogic Server, to offer your Web Services.

    It said the next version of the database willl help DIGEST so authenitcation BASE for HTTP. If the current model of BASIC authentication is a problem, then you should force the use of an SSL (HTTPS) connection. That's why we have the role XDB_WEBSERVICES_OVER_HTTP. If this role is not granted then the DBNWS accessible only using HTTPS.

  • Flop native SOAP service: "Closed connection..", ready for production?

    Our system: Oracle 11 g 2 on CentOS Linux X 64.
    I followed the instructions here: http://www.oracle-base.com/articles/11g/NativeOracleXmlDbWebServices_11gR1.php, well, I can view the WSDL on browser. Now for the real world test, I wrote an application in Visual studio.net 2010 to use the service, after the first time (the value returned successfullly), I had such as:
    The underlying connection was closed: a connection which was to be kept alive was closed by the server.

    I googled and tried all sorts of tricks, like keepalive = TRUE but no joy. Some people suggest that .net has a bug, so I use SOAPUI and SOAPsonar, which returnes same error "the underlying connection was closed." I tried to do the session timeout also not long as possible, still no help, it seems to run out of options, so I tried to configure Oracle HTTP server (instead of the Embeded bridge) a point of entry for /orawsv (I couldn't find any example for this type of HTTP server to help with the configuration of the service web so I took one configuration of the APEX in the dads.conf file) but it did not work , so there is almost the end of my native miracle (no coding) of the web service solution...

    The only case for the Oracle SOAP service is: when I use Oracle APEX, it works fine without the floating point operations. It seems that every customer non-Oracle will not take SOAP Oracle of XDB service...

    Issues related to the:
    1. someone else has real work situations using the native client NON-Oracle with Oracle XMLDB application web services?
    2. it is possible to configure the server HTTP of Oracle 10 G works with this native services?
    3. I missed any parameter on xdbconfig.xml so will not happen this kind of condemnation to death? (almost everything is by default except the HTTP PORT #)

    Suggestions and advise are greatly appreciated

    Oracle APEX doesn't use SOAP or SOAP provider... It uses EGP that is a completely different implementation, the fact that it works or fails is not relevant to the review of native database web services...

    1. someone else has real work situations using the native client NON-Oracle with Oracle XMLDB application web services?

    I wrote a number of applications that use controls of the browser XMLHTTP to call Soap Services... They have been tested with IE and FIREFOX. I also tested extensively with XMLSPY (Altova) SOAP Infrastructure...

    2. it is possible to configure the server HTTP of Oracle 10 G works with this native services?

    No native Web Services are part of the Oracle 11 g database.

    3. I missed any parameter on xdbconfig.xml so will not happen this kind of condemnation to death? (almost everything is by default except the HTTP PORT #)

    Is not sound as it assuming you can get a following WSDL URL

    http://NomServeur/orawsv? WSDL

    SOAP is based on HTTP, which is a stateless protocol, so the connections should not be opened once the request is completed...

    You have (or you can download a trial) of XMLSpy and test with this stack...

    Can check you for all shared servers errors reported in the alert.log, found the trace of the server directory

    Any suspicion that how create and access pl sql web service returning multiple lines?

    I use java not and do not have access to tools such as JDeveloper.

    Thank you!

    The real problem is that collection types are not supported for the return parameters.

    The solution is to wrap the collection into another object.

    Here is an example of work based on your settings:

    CREATE OR REPLACE TYPE test_rec is OBJECT (
  empno  number(4)
, ename  varchar2(10)
, hiredate date
);
/

CREATE OR REPLACE TYPE test_array AS TABLE OF test_rec;
/  

CREATE OR REPLACE TYPE test_array_wrapper is OBJECT ( arr test_array );
/

CREATE OR REPLACE PACKAGE test_pkg AS
  function get_rows(p_deptno in number) return test_array_wrapper;
END;
/  

CREATE OR REPLACE PACKAGE BODY test_pkg AS
  function get_rows(p_deptno in number) return test_array_wrapper is
    results  test_array;
  begin  

    select test_rec(empno, ename, hiredate)
    bulk collect into results
    from scott.emp
    where deptno = p_deptno;     

    return test_array_wrapper(results);
  end;
END;
/

    The wsdl is then generated correctly:

    SQL> select httpuritype('http://DEV:dev@localhost:8080/orawsv/DEV/TEST_PKG/GET_ROWS?wsdl').getxml() from dual;

HTTPURITYPE('HTTP://DEV:DEV@LOCALHOST:8080/ORAWSV/DEV/TEST_PKG/GET_ROWS?WSDL').GETXML()

    Oracle Web Service

  • German characters problem when calling Web Services via UTL_HTTP

    Dear members,

    I try to call the services of SAP CRM Web of Oracle PL/SQL. I used following code which works very well.
    -- call web service using Oracle UTIL_HTTP packages
DECLARE
  http_req utl_http.req;
     http_resp utl_http.resp;
     lv_request VARCHAR2(32767);
     lc_response CLOB;
     lv_buffer VARCHAR2(32000);
     lv_name          VARCHAR2(256);
     lv_hdr_value     VARCHAR2(1024);     
     l_xml XMLType;          
BEGIN     
     utl_http.set_persistent_conn_support(true);
     utl_http.set_transfer_timeout(600);
     
     http_req:= utl_http.begin_request
                                   ( url => 'http://xyz3ni92.server.xyz.com:8045/sap/bc/srt/xip/sap/crm_bupa_custid_qr/011/customersbycrmid/http_binding'
                                   , method => 'POST'                              
                                   );
     lv_request := '<?xml version="1.0" encoding="UTF-8"?>'
     ||'<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:glob="http://sap.com/xi/CRM/Global2">'

           ||'</soap:Body>'
     ||'</soap:Envelope>';     
     /*set username and password*/
     utl_http.set_authentication (
               r => http_req,
               username => 'WS_USER',
               password => 'WS_PASSWORD',
               scheme => 'Basic',
               for_proxy => false);     
               
     utl_http.set_header(http_req, 'Content-Type', 'application/soap+xml;charset=UTF-8'); 
     utl_http.set_header(http_req, 'Content-Length', LENGTHB(lv_request));
     utl_http.write_text(http_req, lv_request);
     /*Make HTTP call*/
     http_resp:= utl_http.get_response(http_req);
     
     /*read response text from response*/
     BEGIN
               LOOP
                         utl_http.read_text(http_resp, lv_buffer);
                         lc_response := lc_response || TO_CLOB(lv_buffer);
               END LOOP;
     EXCEPTION
               WHEN OTHERS THEN
                    -- ora-29266 end-of-body reached
                    IF SQLCODE <> -29266 THEN
                              RAISE;
                    END IF;
     END;
     utl_http.end_response(http_resp);     
     l_xml := XMLType(lc_response);
     /*Log response for testing*/
     DELETE FROM webservice_log;
     INSERT INTO webservice_log (seq_id,xml_response) VALUES (sqe_Webservice_Log.NEXTVAL,l_xml);
EXCEPTION WHEN OTHERS THEN
          RAISE;
END;
    However, if there are any German character in SAP, then they are replaced by UNWANTED data when they come to Oracle.

    If I invoke continues the same web service tools like SOAP-UI, then German characters do very well. I've also drawn web service queries and answers of the side SAP, and there response shows fine. When it comes to Oracle, they are themselves corrupt.

    I'm sure it's something to do with the character, but I am not able to find where and what should I fix/change.

    Thank you for your help in advance.

    I'm not really experienced with utl_http, but maybe you'll read on SET_BODY_CHARSET in the documentation.
    ISO-8859-1 is the default characterset, until you specify the characters in the attribute content_type and text media.
    But your media type is not text, then perhaps affecting the body charset UTF - 8 can help.
