Dynamic invoking web service via uddi regitry server

Hi,
I need to call the web service dynamically after searching from the UDDI Registry Server. pls give me some reply that how to call the web service dynamic.
Thnx in Advance.
[email protected]

Hi,
Try using the udditest.sap.com   it is the Test Registry provided.
Configuring the UDDI Client and UDDI Server    ::::
To use the UDDI client for publishing, updating, or discovering business services and tModels, first you have to administer the UDDI client as well as the UDDI server using the J2EE Engine Visual Administrator.
Procedure
       1.      Select Web Services Container ® Runtime ® UDDI Client.
       2.      From the Available Registries list, select a UDDI registry.
                            a.      To enter a different Inquiry URL and Publish URL, choose Edit Registry and enter new locations.
Make sure that the URLs contain a value. If they do not, then add the port value manually (for example, localhost:50000).
                            b.      To add a registry to the Available Registries list, choose New Registry.
                            c.      To remove a registry from the list, choose Remove Registry.
       3.      On the UDDI Server tab page, choose New User and enter the corresponding data. For more information, see Managing the UDDI Server in the Administration Manual.
Using the Visual Administrator, you can create users for а local test registry only.
Create the User here for the test registry used.

How to invoke web services in sequence in ESB?

Is there any way to invoke multiple services (web, adapter) in a sequence using only the ESB? (I don't want to bring in BEPL).
Something like this:
Read File using File Adapter into schema
|
v
Invoke database adapter to retrieve data and use it to enrich schema
|
v
Invoke web service to retrieve more data and use it to enrich schema
|
v
Send enriched schema to a final web service to perform some operation.
Thanks in advance.

From a technical standpoint, all I want to do is move data from point a to endpoints b, c, and d, and then move the reply or the fault from one of endpoints b, c, or d (whichever one the request went to) back to a.
The "business logic" along the way is at 3 places:
(1). To enrich the data that's being moved. The enriching data is in a database someplace. The logic that determines what that data is in the database is in the original data (message).
Something like this:
//Based on values in the original message, get some row
If OriginalData.Body.field1 = X and OriginalData.SOAPHeader.field2 = y then retrieve Database.Row Z from the database
then
//Enrich the original message with the data from the retrieved row
OriginalData.Body.field3 = Database.Row Z.field9
(2). To decide where to move the data, i.e. b, c, or d. The decision to route the data dynamically retrieved from a web service.
Something like this:
Rule 1: If OriginalData.Body.field3 = A and OriginalData.SOAPHeader.field1= B then move data to endpoint b.
Rule 2: Or If OriginalData.Body.field2 = C and OriginalData.SOAPHeader.field4= C then move data to endpoint c.
Rule 3: Or If OriginalData.Body.field5 = C and OriginalData.SOAPHeader.field6= C then move data to endpoint d.
... and more combinations.
So, send web service the enriched data and it applies rules Rule 1, and it sends back "b". Send web service the enriched data and it applies rules Rule 2, and it sends back "c". Send web service the enriched data and it applies rules Rule 3, and it sends back "d". In this way, adding new rules to the web service lets the customer dynamically "grow" new endpoints.
(3). To transform the data from the format of point a to one of the formats of endpoints b, c, or d. The decision to transform the schema of the data is taken based on the outcome of the business logic applied in (2) above.
This is a sample use case that my customer is using to compare Oracle's ESB capabilities with other vendors', and I have to work within specific boundaries.
So, as I stated in my first post, I cannot use BPEL. All I have to establish is whether Oracle can do this using ESB.

Adobe Flex invoking web services

Hi,
I tried to install the AS Proxy generator plugin as described in following tutorial:
Link: [How to Develop Flex Applications that Invoke Web Services|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/20536f87-b5a1-2a10-06ad-c15369468e0e?overridelayout=true]
Unfortunately I got an error when executing step 2 "Add runtime project to your workspace". When doing this I get an warning message from adobe flex:
A problem occured when opening projekt "runtime". Try quitting and restarting the application. If the problem persists, you might be using an unsupported project version, or your project files might be corrupted.
I imported the runtime project in the flex builder in the following way:
File->Other->Existing Projects into Workspace, selected the archive file runtime.zip, Finish
When restarting AdobeFlex I get the same message again.
I tried this in the follwing system environment:
Adobe FlexBuilder 3.0
Windows Vista
The tutorial remarks that it apllies to SAP NetWeaver CE, FlexBuilder 2.0, Windows XP; may work with other platforms.
I am not sure if this is the reason why it doesn't work.
Has anyone experience with my used system environment? Any help is highly appreciated....
Best Regards, Eddy

Hi Edgar,
i think your method of importing the runtime library is not the correct.
- Unzip the runtime.zip file in your disk
- On Flex Builder, right-click on your flex proyect root, and select "properties"
- Select "Flex Build Path"
- In "Source Path" tab, click on "Add folder"
- Select your runtime folder
- Click OK
I expect this help you

How to access/invoke Web Service from BPM Process

The following steps required to attach and invoke web service method from process:
1) Add a module in the catalog for ex WebServiceMO
2) Add WebService Catalog component demoWebService in WebServiceMO
3) Put ur WSDL address in WSDL address field like "http://localhost:8080/test/test?wsdl"
4) Click next to introspect the web service it will import required files and setting from the url to your project
5) Now for invoking webservice just call the method for ex.
@return as String[]
getTestStringList(TestInterfaceService, out @return : @return)
logMessage "web service calll result >>"+length(@return)+">>>"+@return[0]
Here @ return is the return from webservice call.
this way u can access web service from BPM process.
Edited by: Anurag Yadav on Jul 17, 2009 2:19 PM

I have a web service which does not return any value but when I introspect the web service, I have an out parameter to it.. Not sure why?
For e.g.
TestServiceListener.addTestNotes(TestNotes : testNotes, out TestNoteResponse : testNoteResponse);
So here I see an out parameter, but my web-service has no out parameter...
Any idea why is this happening?

Invoking Web Service From PL SQL package

Below is the sample code to invoke web service from pl/sql package using UTL_HTTP:

UTL_HTTP.begin_request
'http://'
|| lv_hosturl
-- || '.net/soa-infra/services/finance_rt/Payments/paymentsprocess_client_ep',
--new url
|| '.net/soa-infra/services/finance_rt/PaymentsReq/paymentsprocess_client_ep?WSDL',
'POST',
'HTTP/1.1'
UTL_HTTP.set_header (http_req, 'Content-Type', 'text/xml');
-- since we are dealing with plain text in XML documents
UTL_HTTP.set_header (http_req,
'Content-Length',
LENGTH (lv_soap_request)
UTL_HTTP.set_header (http_req, 'SOAPAction', '');
-- required to specify this is a SOAP communication
UTL_HTTP.write_text (http_req, lv_soap_request);
http_resp := UTL_HTTP.get_response (http_req);
UTL_HTTP.read_text (http_resp, lv_soap_respond);
UTL_HTTP.end_response (http_resp);
resp := XMLTYPE.createxml (lv_soap_respond);
End;

Hi,
there are a lot of option to make plsql web services .
First you can stay with jdev 10.1.3
Use the xmldb servlets
use jdev 11g tp4 to create plsql ws and upgrade to jdev 11g production
And I think in the next release of jdev it will be back , there are more options which disappeared like the adf bc sdo ws or jmx datacontrol etc.
thanks Edwin

Invoking web service from OBIEE11g failed socket timeout

Hi,
I encountered an error when I invoke web service from OBIEE 11g. The web serivce resides on Websphere running on other machine.
An error says that "Invoking web service failed due to socket timeout." and it seems that it stopped in just 40 secs.
Is there any settings of WebLogic server to avoid this? This web service normally runs for more than 60 sec.
I have checked several parameters in WebLogic admin console and changed those values, but I still receive the same error.
Invoking the same web service from SOAPUI sustains for more than 60 secs.
Regards,
Fujio Sonehara

Don't be too surprised. Sun figured this bug out in short order. I got the same error message when trying to do the same thing, just for the heck of it. Reference this article for details.
http://java.sun.com/webservices/docs/ea2/jaxrpc/ReleaseNotes.html
It contains information about bugs fixed in the WSDP EA2. So in answer to your question, download the newer pack from
http://java.sun.com/webservices/downloads/webservicespack.html
and your bug will go away. Happy Coding.

"Error while parsing SOAP XML payload: no element found" received when invoking Web Service

Running PB 12.1 Build 7000. Using Easysoap. Error ""Error while parsing SOAP XML payload: no element found" received when invoking Web Service".

Maybe "extraneous" is an incorrect term. Apparantly, based upon the writeup within Wiki, the parser I am using does not interpret the """? How do I find which parser is being utilized and how to control it?
<<<
If the document is read by an XML parser that does not or cannot read external entities, then only the five built-in XML character entities (see above) can safely be used, although other entities may be used if they are declared in the internal DTD subset.
If the document is read by an XML parser that does read external entities, then the five built-in XML character entities can safely be used. The other 248 HTML character entities can be used as long as the XHTML DTD is accessible to the parser at the time the document is read. Other entities may also be used if they are declared in the internal DTD subset.

Invoking web service using Weblogic Workshop (JCX)

Invoking web service using Weblogic Workshop
Posted: 5 Jan 2005 23:31 PM Reply
Hi,
I have WSDL from which I have generated a web service control (.jcx) using Weblogic Workshop.
I need to write a client which will invoke the web service using the control.
Can someone help me on how to go about this ?
BTW .. I also tried the clientgen route and tried to generated the proxy jar from the WSDL but wasn't successful because of a existing clientgen bug.
Refer bug

Hi,
if the consumer of the webservice is a control-aware consumer ( pageflow, control, process ) simply drag the control to this consumer and the control variable is ready for use.
if the consumer is not control-aware, try to generate a proxy using eg. the axis tool, or handcode your proxy class.

Invoke web service with DTO

Hey guys,
I am quite new in using BPEL. My first test worked fine, but know I have an issue, which I can not solve. Invoking web services with a basic return value is no problem. I could also you a dto object including some basic variables in order to invoke the web service without having problems.
But when I have a dto object as return value, I get the following exception.
Could someone give me a hint to fix my problem...that would be great!
Thanks alot!
Sven

Invoking web service with HTTP authentication using OdiInvokeWebService

ODI Version 11.1.1.3.0

I've gotten past the original error by importing the security certificate of the Web service into my keystore/truststore. I'm also running the process on SOA 10.1.3.1.0. Now when I invoke the Web service from the BPEL process I get this error:
exception on JaxRpc invoke: HTTP transport error:
javax.xml.soap.SOAPException: java.security.PrivilegedActionException:
javax.xml.soap.SOAPException: Bad response: 403 Forbidden
I've tried passing the credentials every way I can -- partner link properties, Oracle Web Services Manager, whatever -- and still get the same error. I would expect to see a 401 error for problems with credentials, not a 403.
Any suggestions?
Thanks for your time.

Invoke Web Service - An unknown error occurred

We recently moved our Runbooks to Windows Server 2012 R2. The Invoke Web Services activity has not been executed previously on this installation and thus no cache files.
Entering any SOAP WSDL into the WSDL Properties fields then clicking Method throws an error An Unknown Error Occurred.
Do not see any additional information in Logs or Event Viewer.
All WSDLs are known to be good and are consumed by other applications, including PowerShell.
Thoughts?
Edit: Tested on another installation and it works. I do not have the option to reinstall the server that is facing this issue.
Moved On

Resolved the issue. Team forgot to install R2. The working environment has R2, after upgrading the issue is resolved.
It would appear that Invoke Web Services in Orchestrator 2012 is useless.
