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,
XaM

Yes it is,
You could use a java stored procedure

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 need to call it again transparently for the user. 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.

Web Service Call from PL/SQL

Hi Gurus,
I am calling a Web Service(RoadNet Application) from Oracle PL/SQL(11g Database). My code is working for simple xml type to get the response. But when I tried with a complex XML type, I am getting the response, but it does not have the complete output.

I use SOAPUI (OpenSource/free version) to interrogate the web service (read wsdl) and format a sample SOAP envelope to use.
I then use UTL_HTTP and code a HTML POST for that web service, using the SOAPUI generated envelope as template. Supporting WSSE is also not a problem (easily done using PL/SQL).
I posted an example of my approach in {message:id=10448611} almost a year ago - and recent experience having looked at both UTL_DBWS and the plan vanilla PL/SQL HTTP approach, I still recommend the latter.

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

There is also an APEX package wwv_flow_web_services, but I couldn't find any documentation on it.

Restricting Web Service Access from specific machines (IP)

Is there any way by which we can restrict access of our web service to some specific machines i.e., restricting to some specific IPs.

maybe a Filter helps you since you can know the remoteIP from the httprequest
http://java.sun.com/products/servlet/Filters.html
public class TestFilter implements Filter {
FilterConfig config = null;
public void init(FilterConfig filterConfig) throws ServletException {
this.config = filterConfig;
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) servletRequest;
HttpServletResponse response = (HttpServletResponse) servletResponse;
String ssoToken=null;
System.out.println("+++++++ENTRANDO AL FILTER DE WS++++++++");
System.out.println("+++++++IPLOCAL++++++++"+request.getLocalAddr());
System.out.println("+++++++HOSTLOCAL++++++++"+request.getLocalName());
System.out.println("+++++++IPREMOTE++++++++"+request.getRemoteAddr());
System.out.println("+++++++HOSTREMOTE++++++++"+request.getRemoteHost());
System.out.println("+++++++REMOTE USER++++++++"+request.getRemoteUser());
System.out.println("+++++++Filter chein++++++++");
filterChain.doFilter(servletRequest,servletResponse);
System.out.println("***despues de doFilter****");
public void destroy() {
config = null;
}

hi
Check for the methods like setuser and set password for your webservice
Request_<webservicename> request=new Request_<webservicename>();
 wdContext.nodeRequest_<webservicename>().bind(request);
 wdContext.currentRequest_<webservicename>Element().modelObject()._setUser("sdnuser");
 wdContext.currentRequest_<webservicename>Element().modelObject()._setPassword("sdnuser");
 wdContext.node<webservicename>Request().current<webservicename>RequestElement().setRequest(company);
 try
 wdContext.currentRequest_<webservicename>Element().modelObject().execute();
 catch (Exception e) {
 wdComponentAPI.getMessageManager().reportWarning("Exception:"+e);
Hope this helps,

Does Oracle817 support Web Service call from PL/SQL Procedure?

Asynchronous web service call using PL/SQL

Hi Guys,
i'm using Apex 4.1.
Is that possible to invoke a web service asynchronously within PL/SQL code block ? If so,
How can i access the return value of the service when execution of that web service completes ?

Bolev wrote:
We have (Oracle 10g) automated process (ETL) based on internal data. Now there is an offer to incorporate existing web service call (let's say for additional record verification) in this process. Service call (I do not know what type of it yet) is using data from remote database which is not ours.Web service calls from PL/SQL is not that complex. You can use the standard UTL_HTTP package as shown in {message:id=4205205}.
I never heard anybody goes this way especially for ETL processes.Well, if you push a million rows through the ETL process and the call overhead for the web service call (assuming perfect network and web server response) is 1 sec, that translates into 277+ hours of runtime alone for the validation to be done via web service.
So yeah - it would seem kind of silly to use something like a web service to validate large volumes ETL data.

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.

Enable Web Service access for a Web service-enabled client

Hi,
I want to access data in Oracle CRM On Demand from a Web services-enabled client. The "Oracle Web Services On Demand Guide" suggest the Web Services Access should be granted by Customer Care representative. By default, this access is enabled for the Administrator role for new companies. However my admin account can't access web services from a web enable client.
Can anyone please suggest me the setting/step that i need to enable Oracle On Demand Web service access from a Web services-enabled client?
Note: I am new to oracle on demand so my query can be a silly thing.
Thanks & Regards

I was able to resolve this issue. Actually, i was trying with trial account that don't allow the OCOD web service integration.

Configuring SSL to make a HTTPS web Service call from XI

Hi All,
We are making a https web service call using soap adapter from XI. Looking at the various posts and SAP help links, we are configuring SSL for the same.
The procedure given in SAP help has been followed to configure SSL but with no luck. If someone had done this could you please give a step by step procedure to configure SSL, we might have missed out on something.
Also are there are any other settings apart from SSL to be done to make a https web service call using soap adapter from XI.
Cheers,
Chandra

I have an old pl/sql "helper" package, originally written to make SOAP Web Service calls from the database - it uses UTL_HTTP to invoke the target services.
I now need to make SOAP Web Service calls - from an 8.1.7.4 database

Can anybody suggest a means of making SOAP Web Service calls from an 8.1.7.4 database ?I think you'll be very lucky to find anyone here who still has access to a version of Oracle that is that old.... I mean... that's like what? 15 years old at least? I'm surprised you've still got hardware that can run that.
It would probably help if you could post what code you've got and explain which function(s) it's complaining about, as I doubt people will want to guess.

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

Web Services call from SOA to BI Publisher

Hi,
I have never worked on this web service call from SOA to BI Publisher funcationality and I am strugulling to understand on how this woks.
My requirement is that SOA will call BI Publisher on a parameter basis eg( some id) to a report and BI publisher should pick that id and execute the report and place the PDF file (file name is combination of id and date) into specific location in the FTP server and in return BI Publisher should send the response to SOA defining the file name and location of the FTP server.
Can anyone please help on this. This is a big sore on my head.
Thanks in advance.
Regards,
Apk

Thanks for your replies.
Actually I am working on Forms 6i version , so does same solution works on Forms 6i as well.
Also this application is for address search, so user provides for some key like PostCode etc and then call the Webservice and it will give you list of options.
Now user will choose and confirm one address.
Do all this interaction possible using UTL_HTTP?
After going through link provided , I need to implemented in following steps:-
1) Using JDeveloper 10.1.3.1.0 Create a SOAP_REQUEST.
2)Create a wrapper program who calls Web Service.
3) Call this Wrapper Program from our form and PL/SQL Package.
Please let me know if this sounds OK.
Thanks a Ton,
