  Based on the following pages, it says we can publish web services from PL/SQL to certain kinds of application server. I have the application development Oracle APEX and wide writing PL/SQL packages. However, I don't know much about the web service and architecture that I need to get there.

  It's a roundabout way to create a web service of the IMO. It encapsulates calls to PL/SQL in Java code in order to define a web service. That is not necessary and approach classic head-up-DOS of Java fanbois.

  If an HTTP call are possible directly in PL/SQL, so why not do? So why put a layer of major and complex Java (usually on a separate platform of h/w too) between the appellant and the PL/SQL to provide a web service interface? How is it better?

  Fewer moving parts means less complexity and improve performance. Less performance problems and problems. Easier to code and maintain.

  Reality: it is not necessary for the external moving parts create a WebService from PL/SQL. And to do this, the Apache/mod_plsql or EPG of XDB is required to provide the very basic communication interface layer (at the protocol level) between the appellant and the PL/SQL web service procedure.

• Urgent: The PL/SQl web service call fails with XML parsing

  Hello

  NS is a string that contains the declaration of namespaces.

• Basic questions about the PL/SQL web services and data source names

  Hello
  
  I've successfully generated a web service for a procedure from PL/SQL packaged JDeveloper 11.1.1.3.0).
  
  The following code was generated in the base class for web services:
  

   __dataSource = (javax.sql.DataSource) __initCtx.lookup("java:comp/env/jdbc/dbconnectionDS");

  However in the weblogic server, the data source name is jdbc/Gisele for deployment fails in a first time.
  
  What is the recommended procedure to solve this problem? The obvious solution is to manually change the source - that's what I did and it worked fine. However if I re - generate the web service I won't lose my change. Is there a better way to do it?
  
  Another question - in the web.xml file that is generated, there is a resource-ref to the data source. I was hoping that change the data source name it would help, but it didn't work. What is - it used to in this context?
  
  Thank you
  Luis

  I forgot to add, so in case some time later and you want to update the connection to your service details, all you have to do is to add the following entry in your weblogic.xml:
  .
  
  JDBC/ref_name_from_web. XML
  JDBC/new_jndi_name
  
  .
  And in this way, you will not have to change any code level to point your web service to another connection.

• Oracle BI Publisher Web Service

  All the:
  
  I am writing an integration of Oracle BI Publisher PublicReportService web service (that is, http:// < server name >: 9704/xmlpserver/services/PublicReportService); in the code that I wrote, I'm deleting report history planned using the deleteScheduledReportHistory operation provided by the service. The call to the service is successful, and the service responds with a value of "true", indicating that the report history has been deleted. The HTTP request and response to a call from the sample is copied below for reference (obained using WireShark). However, once the call is finished, when I navigate to the page of history annex Oracle BI Publisher (i.e. http:// < server name >: 9704, xmlpserver, servlet, myhistory), I find that the story for the job is still listed.
  
  Am I misunderstood what the deleteScheduledReportHistory operation is supposed to do? Everyone knows about similar problems with this service operation?

  The version of Oracle BI Publisher that I use is 10.1.3.4.1

• SOA Gateway - timeout when calling a web service custom Pl/SQL using SOAP

  Hello

  I developed and deployed my PL/SQL web service custom repository integration SOA Gateway.

  The web service works well, but sometimes its execution time exceeds 60 seconds, and I get the following time-out error: java.net.SocketTimeOutException: Read timed out

  Here's my env:

  Product	Oracle E-Business Suite integrated SOA Gateway
  Version of the product	12.1.3
  Operating system	IBM AIX on POWER Systems (64-bit)
  OS version	6.1

  I would like to know if there is a way to increase this time-out?

  EDIT:

  I took a quick glance at this doc errors of timeout in Web Services deployment (Doc ID 1073270.1( )

  and modified the $ORA_CONFIG_HOME/10.1.3/opmn/conf/opmn.xml file

  then bounced oacore, oafm, but it did not work.

  EDIT 2:

  I tried to change the timeout setting in the file httpd.conf ( $IAS_ORACLE_HOME/Apache/Apache/conf/httpd.conf )

  restart apache and the server, but it didn't work.

  Thank you

  Kind regards

  Simon

  In fact, I tried to play with the values that you mentioned, I put the maximum Heap space in JAVA to 2048M and in Apache timeout to 3600 seconds and after a wait of cca. 20 minutes I got the answer I needed the SOAP service.

• 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.

  Web Services using native Oracle XML DB

• 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.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,

  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...

  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()

  I've been using Oracle APEX since its initial release (1.6 HTMLDB?).

  Has been called Marvel project. :-)

  However, web services is really a new object me - until now, I need to learn more about this topic.

  A web service is not that much different. He gets a HTTP request and responds to it. The difference from a technical point of view is the payload. A SOAP payload is received and a load XML is the answer.

  I think that, especially with Java developers, which is described by using several acronyms and definitions more and more moving parts. But it's especially stuffed animals. This is the client-server tcp using the HTTP application protocol to send and receive payloads.

  This means that all of the basic concepts and standards and security issues with HTTP client-server, remain valid.

  What I'm not clear, is that, with respect to web services Oracle XML DB, do I really need to set a port in the server that is running the database for the XDB HTTP listener

  For the web service procedure or method to receive the call and answering the call, a layer of HTTP communication is necessary. This can be Apache, IIS, Tomcat or servlet HTTP in XDB.

  I feel very uncomfortable allow access to resources of database directly through a browser without worrying it's http or https.

  I don't see that as the real problem. If the customer uses OIC via tcp or HTTP over tcp to communicate with the database, basic security issues and principles remain the same.

  What offer the XDB is the elimination of a layer external s/w (like Apache) to deal with the aspect of communication tcp and HTTP interface. This can be useful sometimes (deletes an external point of failure and external complexity). Maybe it's not ideal at other times. As usual, it depends on the security requirements and the physical communications infrastructure.

  We can expose web services Oracle XML DB with Oracle HTTP instead of use the XDB HTTP listener in an Oracle database?

  Yes. The caller specifies what exactly? A URL that refers to a procedure from PL/SQL web active. So if that is served by Apache mod_plsql or via a servlette XDB is neither here or there - both are interface HTTP communication layers. Their main goal is to provide the interface between the client and the web service.

  I find the documentation on web services to confusion at times because it is too abstract and does not address the fundamental workings of its operation. And Oracle API web service in the data base is (AFAIK), on ito Java classes complex configuration and use of the PL/SQL wrappers and cryptic in error responses.

  So when it comes to web services, I generally prefer to roll my own using PL/SQL only.
