Calling web service request from PL/SQL

I am trying to create Apex page with stock quote ticker - like what Yahoo has on their page. I have the right web service and have put together a page which works when you submit (created by the wizard). Instead of clicking submit to refresh the page I want to use Ajax to do this but for this purpose I need to know how to call web service from PL/SQL so I can do this in my on demand process. Any ideas?

George,
The documented way to call a web service using PL/SQL is to use UTL_DBWS package.
Here are a couple of links that may be useful:
http://www.oracle-base.com/articles/10g/utl_dbws10g.php
http://www.oracle.com/technology/sample_code/tech/java/jsp/callout_users_guide.htm
There is also an APEX package wwv_flow_web_services, but I couldn't find any documentation on it.

Calling a web service reference from PL/SQL

Hello,
could anyone give me a hint how to call a web service that is defined as web service reference from a PL/SQL page process (PL/SQL anonymous block).
Many thanks in advance
Lukasz

>
The problem is that I have a PL/SQL page process that processes the result that was returned by a web service (triggered by web-service page process (-; ) and <b>need to call it again transparently for the user</b>. If there is a way to execute a page process from this PL/SQL block the question would be answered as well.

Same parameters and repeating at pre-defined time intervals? If yes, use Javascript as described here.

Trouble Calling Web Service Function From Runbook

i have downloaded the OrchestratorServiceModule web services module from CodePlex and i am successfully using it in runbooks. But for some reason when i call the runbook from another runbook, the Get-OrchestratorRunbook function returns no data
($runbook variable is $null). The error message states the runbook name that i provide "is not found in Orchestrator". This function works well when the runbook is called directly. The variables
are populated. $creds is set to $null. there are no errors regarding installing the module or finding the function. any ideas as to why this would succeed when the runbook is called directly but fail when called by another runbook?
$runbook = Get-OrchestratorRunbook -serviceurl $url -runbookpath $rbpath -credentials $creds

Help needed: Handling web service requests from a J2SE application

I want to write an J2SE application that is able to receive and parse web service requests. I want the application to, when started, start listen for incoming requests on a specific port.
So far, I have embedded Apache Tomcat and Apache Axis in my application so that they parse the incoming requests and pass them on to my application logic.
This seems like a very cumbersome way of doing it. I have included an almost full J2EE server in my application just to be able to parse web service requests.
Is there an easier way? What technologies could I use? Any help would be greatly appreciated.

Thanks for the help!
It seems awfully complex though. Couldn't one just
listen to incoming requests on a socket and use some
good tool to parse them?
Of course you could. One of the projects in that list is a 1 class java file. It could listen for requests, then you could parse the posted SOAP messages using JAXP and pass the requests on to your application. This will require a good understanding of SOAP however, and it may end up taking more time than simply using the JWSDP with a slightly beefier server.
Given that there is only a handful carefully
specified requests that the application needs to be
able to respond to it seems overkill to include a
full servlet enabled server...

Hi,
I used web service refences to create call this web service and when I tested the web service in the test area in web service refences
it is working fine and it is giving the foloowing

Urgent - Error calling web service generated from plsql package

Hi,
I am using Jdeveloper 10.1.3 production release.
I am trying to publish a plsql packaged procedure as a web service.
My first question is -
When I am publishing the plsql API as a WS, should I choose the style Document/Wrapped or RPC Literal? Document Wrapped is the default in the wizard.
My second question - Depending on whether I choose Document/Wrapped or RPC Literal style, I get 2 different errors when I try to run the client java file (generated by Jdeveloper) that calls the web service. The client java compiles successfully but when I run I get these messages:
Document/Wrapped error -

Now all the classes are generated by JDeveloper automatically from the plsql API. So I am not sure why the errors occur and how to fix these.
Also, these errors are occurring on plsql APIs that have input or output parameters of plsql record type or pslql table of record type. These errors don't occur if the api is simple with scalar input or output parameters only.
I would appreciate any help on how to resolve these errors.
Thanks,

Hi,
I'm wondering if the problem is actually that the client is failing to connect to the server correctly. Can I suggest that you switch on the HTTP Analyzer and see what comes back there.
Is it possible it is a proxy problem? If you are working locally then I first suggest that you ensure that the Web Browser Proxy is off (see Tools -> Preferences -> Web Browser Proxy) - and that there are no exceptions listed (either with the proxy on or off) before you start the HTTP Analyzer.
As to Doc/Wrapped or RPC. see this blog entry for a little more explanation:

Web services access from PL/SQL. It is possible?

Hello,
I need to access some data from one database, using a Web Services (it's the only way I have permisson). It's possible to do that from an PL/SQL function/procedure from another database?
Thanks,

Yes it is,
You could use a java stored procedure

Programatically calling Web Service DataControl from App Module

Hey,
I've been following the 4GL ADF tutorial recently but have a question regarding initiating a web service call instead of using an entity object. The tutorial I am using is located at:
http://www.oracle.com/technology/products/adf/learnadf.html
On Page 102 - Adding Custom Methods to the Application Module there is a little piece of code to transfer some data from a transient view object into an entity object. The code is
public void createNewServiceRequestFromGlobals() {
ServiceRequestImpl sr =
(ServiceRequestImpl)getDBTransaction().createEntityInstance(ServiceReques
tImpl.getDefinitionObject(),null);
Row globalsRow = getGlobals().first();
sr.setProblemDescription((String)globalsRow.getAttribute("ProblemDescript
ion"));
sr.setProdId((Number)globalsRow.getAttribute("ProductId"));
getDBTransaction().commit();
What I would really like to be able to do is use a web service datacontrol instead of the entity object. Can anyone point me in the right direction?
Thanks,
Mark

I have the same problem
1. I have a data control what is a web service client to URL https:
2. JDev 11g build a model
3. I need to call this data control from java class
4. My java class simply must call a method of the web service, this method I see in the DAta Control, with the parameter and just return the String,
5. this is not a Web Application, is swing, I not have a Context
method in WS
public String ConsultaPlaca(String arg1);
How I can implement this?
Just in Java Class, not in page JSP. the java class is a library of other Java class, I need to build a file .jar

Web Service (SOAP) From Oracle Forms

From the exaples of calling web services (soap) from pl/sql, it seems very poor and troublesome. I've seen a few articles with good points about why not to do this from pl/sql. So, I was hoping someone in the forums could share their opinions and approaches to using web services from forms based applications. I would ideally like to hear reasons people chose not to use pl/sql.

There are some examples of calling web services from forms on the Forms OTN page - works fine although I would encourage the use of the new JVM pooling features as this will aid scalability and performance.

As for 'pros and cons'... there's nothing to compare against... either you want to call a web service or you don't.

Call web service from pl/sql

Dear All,
I have web service where I need to take picture as binary stream and insert it in the blob.
Which is the best way to call web service and store picture as binary stream (jpg file) into blob?
Kind regards,
E.

Thank you very much for helping me to invoke web service into my database.
I got message, now I need to decode picture from base64binary. Is there any way to do it trough pl/sql or I need use java?
My database is 10g.

Script example trigger web service call and populate request from adobe

Hello,
I'm trying to make a adobe interactive form that needs to be populated by a web service. I have one field : In the dataconnection that is the input for the web service request and this is bound to the request. I have a button that is connected to my web service. After filling in a new value and pushing the button I want the web service request to be triggered.
Thus anyone has a coding example or more information about using web services directly from within a Adobe Interactive form ?
thnx, Jasper

Hi Jasper,
You may refer the Adobe ddevelopment center for the docs related to the execute property of the button to trigger a web service.
<i>Alternatively, if you do not want to create a button to execute a call to a Web Service, you can do it via Script.
Assuming your Data Connection is named LeasePayment
For JavaScript:
xfa.connectionSet.LeasePayment.execute(0);
For Form Calc:
$connectionSet.LeasePayment.execute(0);
execute(0) indicates no data merging
execute(1) indicates all the data in the data DOM will be remerged.</i> - Adobe doc.
hope this will help.
Thanks andRegards,
Anto.

Calling web service from oracle forms 10g

Problem Description:
I'm following the steps as per the doc:
http://www.oracle.com/technology/products/forms/htdocs/10gr2/howto/webservicefromforms/ws_10_1_3_from_forms.html
to create a java stub to call external web service and then use java importer in oracle forms to call this web service from oracle forms.
WSDL for external web service used is http://gend:83/DesignService.svc?wsdl
The service was developed by us.
Calling the web service using JDeveloper works fine but when I complie in Oracle Forms it returns wrong number of types of arguments in call SENDHELLO.
The code from oracle form to call web service is as below:
DECLARE
jo ora_java.jobject;
xo ora_java.jobject;
rv varchar2(2000);
ex ora_java.jobject;
str varchar2(100);
BEGIN
jo := GendServiceClient.new;
rv := GendServiceClient.sendHello('Nora');
EXCEPTION
WHEN ORA_JAVA.JAVA_ERROR then
message('Unable to call out to Java, ' ||ORA_JAVA.LAST_ERROR);
WHEN ORA_JAVA.EXCEPTION_THROWN then
ex := ORA_JAVA.LAST_EXCEPTION;
message(Exception_.toString(ex));
END;
Any help/ideas on this is greatly appreciated. Thanks.

My primary skill is PL/SQL but the only information I found on Oracle's site to call a web service from a 10g Form was creating a jar file and importing the java class. Since I don't want to ask our corporate IT to make changes on the UNIX box for the jar files I went a different route.
I use UTL_HTTP.BEGIN_REQUEST to call a URL then load I load the data to a table as a CLOB since we have more than 4000 characters. Now I need to parse the XML and load it into a form. I have never done this so if there is a helpful site please let me know. I have looked at several sites but none do what I want.
Thanks
