CALL A WEBSERVICE FROM FUNCTION

HI to all,
sorry for my question, but never used webservice since now:
however would like to know if it's possible to call a web service from a PL/SQL function.
thanx a lot

I solved it myself by using utl_dbws package. utl_dbws package is compatible with 10g release2(10.2.0.2) and next higher versions. By using utl_dbws package, it is easy to call a webservice.
Before i was using utl_http package and a my function was using xml tags heavily. In this case we have to careful in entering xml tags, so that we will return the exact output message.
Thanks and Regards,
Mahesh

How to call a webService from WebDynPro ABAP ?

We are trying to call a webService from WebDynPro-ABAP application. It is not working, While if we are calling the WebService from a Report, it is working.
How exactly do we call a WebService from a WebDynPro-ABAP application?
What are the main steps involved ?

Hi Phani,
You will need to create a service call as follows.
Right click on your WD component name and select Create->Service Call
The wizard will guide you through a series of steps to make a Web Service Call. On the 3rd screen, it will give you options such as Function Module, Web Service, etc
Before making a service call, you will need to create a proxy for the Web service in the ABAP Workbench using a WSDL document as a basis. To create or consume Web services, you will need the authorizations associated with the role SAP_BC_WEBSERVICE_ADMIN.

Provide Asynchornous Webservice from Function Module

Hi!
I need to create a webservice to provide master data. My scenario do not use Process Integration, so I create the webservice from function module (Remote-Enable Module) through SE80.
When service is created I can see in the configuration tag that is not possible to change to asynchronous mode.
I want to create asynchronous webservice because I need to return master data. Selecting this data consume a lot of time, so in order to avoid timeouts I think is better to create asynchronous webservice.
May be I am wrong but I think is not possible to create async webservice without PI.
All documents I have read until now show async comunication through PI and using proxy clients but I have not found the case I am talking.
Thanks

Thanks Raja,
I think I'm confusing about synchronous / asynchronous concept in webservices. I need an example or an explanation where I can understand it. Taking account that I do not have PI, where scenario I'm moving in?
I mean, is it possible that an external client calls my webservice created through FM in async mode? Maybe is the client who has to create the corresponding call to the webservice in async mode and I have to do anything.
Another question related, what does it means the propierty sync/async in a proxy?
I do not understand your sugestion since I think that proxy creaton is relevant in case of the connecting SAP with an external system (I tried it and I have to inform an URL o WSDL).
All documents I have readed have been in the context of PI and I think my case is more simply.
Any more suggestions, links or ideas?
Thanks
Regards

How to create webservice from function module

Hello,
I'm trying to create webservice from function module from. I choose Utilities/More Utilities/Create Webservice/..From function Module. What data should I enter in section "Enter Package/Request" ?
When I check "Local object" checkbox I get a message "Test objects cannot be created in foreign namespaces"
Is there any doc about this procedure (web service creation) with description of all sections ?
thanks for any reply,
Lukasz Ferenc

Hi,
Which SAP product of wich release of which SP are you using ?
The procedure is documented in help.sap.com and in blogs and SDN forum messages.
It means that the use of the SEARCH button should give plenty of answers...
>When I check "Local object" checkbox I get a message "Test objects cannot be created in foreign >namespaces"
As usual, begin your choosen name with an "Z".

Hi Jaya,
Yes. It is possible to call ur custom program using SUBMIT statement.
1. If u have data to pass then build table type RSPARAMS and use below statement.
data:
      rspar_tab TYPE TABLE OF rsparams,
      rspar_line LIKE LINE OF rspar_tab,
SUBMIT report1 WITH SELECTION-TABLE rspar_tab
               AND RETURN.
1. If u want to create variant to the program and use that. use the below statement .
SUBMIT report1 USING SELECTION-SET 'VAR1' "variant
               AND RETURN.

Error while calling PI webservice from EJB

Hi Experts,
We are getting exception while calling PI webservice from EJB which is deployed in CE 7.2. Earlier we used to call the same webservice but from different PI system at that it worked fine. Now we have changed the consumer proxies required in CE and tried to call from CE and it is throwing error. We have checked usernames and passwords that we are using to call the service and that is working fine. PI team tested from their side and li is also fine. We have also restarted the CE system but invain. Can somebody help on this. The below is the trace that we got.

Hi Pradeep,
this looks like if the server is not reachable. Have you checked if both server are able to communicate? Maybe firewall rules block the request.

Calling a webservice from within Bex Web Application Designer

Hi
I have a web-template built with BEx web application designer which also contains textboxes. This text should be stored by calling a webservice (standard BI-documents are not an option).
Can anyone tell me how I could call a webservice from within the BEx web template to store the text contained in the textbox? The webservice-call should include some of the filter-varialbes of the web application.
Is this only possible by the use of a JavaScript WebItem? If so - does anyone have an example of such a JavaScript.
Thanks a lot in advance.
Kind regards.
Christoph

Thanks for your response. The BSP page would work out fine if I only needed to save the data.
But the next time I call the webtemplate, the textarea should be filled by another webservice call with the stored text (so the text can be modified und saved again). This will not be possible by calling a BSP page.
Do yoiu have any suggestions how to integrate the text (return value from the webservice call) into the textbox in the webtemplate?
Kind regards.
Christoph

Oracle BI 11.1.1.7.1: Calling BI webservices from Plsql Procedure: ORA-29532: Java call terminated by uncaught Java exception: java.lang.NoClassDefFoundError

Hi,
     I have a requirement of calling BI webservices from Plsql stored procedure. I generated all my wsdl java classes and loaded them into the database. However, when I tried to call one of my java class using stored procedure, it is giving me"ORA-29532: Java call terminated by uncaught Java exception: java.lang.NoClassDefFoundError".
*Cause:    A Java exception or error was signaled and could not be
           resolved by the Java code.
*Action:   Modify Java code, if this behavior is not intended.
But all my dependency classes are present in database as java class objects and are valid. Can some one help me out of this?

Stiphane,
You can look in USER_ERRORS to see if there's anything more specific reported by the compiler. But, it could also be the case that everything's OK (oddly enough). I loaded the JavaMail API in an 8.1.6 database and also got bytecode verifier errors, but it ran fine. Here are the errors I got when loading Sun's activation.jar, which ended up not being a problem:
ORA-29552: verification warning: at offset 12 of <init> void (java.lang.String, java.lang.String) cannot access class$java$io$InputStream
verifier is replacing bytecode at <init> void (java.lang.String, java.lang.String):12 by a throw at offset 18 of <init> void (java.lang.String, java.lang.String) cannot access class$java$io$InputStream

Calling Java WebService from Adobe

Hi,
Iam using a simple java service. I need to call this WebService from my Online/Offline forms.
When Iam running the form in Portal , Iam getting the following error:
Error attempting to read from file :
http: / / hostname:port/ServiceName/Config1?Style=document.
The way I imported the wsdl. Saved wsdl , merged 3 wsdls and imported in Adobe Form.
Please let me know is there anything else missing here?
Thanks,

Edited by: Uma Anbazhagan on Sep 28, 2009 8:20 PM

Hi,
Regarding this question, I was able to save the wsdl file, make relevant changes as mentioned in help document and consume it.
However , without authentication WS worked fine. The WS with authentication is having issues.
Need to try with latest version and see if this is resolved.
Thanks,

How to call java webservice from plsql procedure.

Hi,
Could any one please provide any reference document for invoking a java webservice from pl/sql procedure.
regards,
Venkat

Hi,
There are basically various platforms where u develop the code with different patterns, though the idea is same everywhere.
1. If you want develop a Java Client to call a WebService from NWDS then Pls refer >>
http://help.sap.com/saphelp_nw2004s/helpdata/en/43/cb2e29578c0262e10000000a11466f/frameset.htm
Note: By default the WebService developed under NWDS is Document Based WebService (i.e. In WSDL the style element would be 'document')
2. If you want to call a WebService from the platform other than NWDS than, Sun's official site would be the best choice to go for.
Pls refer >>
http://java.sun.com/developer/technicalArticles/J2EE/j2ee_ws/#design
Would appreciate if you reward the points if the answer is helpful.

thanks Tugduall for the comments. here are the instructions I followed to create a java stored procedure that can call a webservices. Unfortunately, this seems like a very complex task. Do you have any ideas how I could debug or troubleshoot this issue ?
Please note that I used JDeveloper to generate the client code.
========================================================
1. download the dbws-callout-utility-10R2.zip from OTN at:
http://www.oracle.com/technology/sample_code/tech/java/jsp/dbwebservices.html
2. create an application/project with 1.4 JDK.
3. create a web service by ‘Business Tier’->Web Service->Web Service Proxy->UDDI
4. next… to ‘Search for’, type ‘quote’.
5. from the list select one. For me ‘Quote of day’ was picked.
6. click Next all the way to Finish.
7. from the ‘Application Sources’ select ‘QuotoProxy’ then find its main method.
8. at the section
// Add your own code here, add the line like:
System.out.println("quote "+myPort.getQuote());
9. run it to see its return.
10. cteate a class that has a method to call client method to be invoked (static)
like the following:
package dbws;
import dbws.QotdPortClient;
public class MainClientStub {
public MainClientStub() {
public static String getMyQoute(){
QotdPortClient myClient = null;
try {
myClient = new QotdPortClient();
return myClient.getQuote();
} catch (Exception e) {
e.printStackTrace();
return null;
note that the package name in your project.
11. create a deployment profile as ‘JAR File’. Uncheck the box ‘Project Dependencies’
12. deploy it to the local box. ‘Deploy to JAR File’.
13. unzip the dbws-callout-utility-10R2.zip to get dbwsa.jar.
14. execute the following from command line:
loadjava –user test/[email protected] -resolve –verbose –synonym –grant public to dbwsa.jar myarchive1.jar
loadjava -user test/test@orcl1020 -resolve -verbose -synonym -genmissing -grant public myarchive1.j
ar dbwsa.jar
loadjava -user sys/<sys_pass> -resolve -verbose -synonym -genmissing -grant public myarchive1.jar dbwsa.jar
15. create a function like the following:
CREATE OR REPLACE FUNCTION teststub RETURN VARCHAR2 AS
LANGUAGE JAVA NAME ‘dbws.MainClientStub.getMyQoute() return java.lang.String’;
16. Run at sqlplus: Select teststub from dual;

#2170 error calling a webservice from Xcelsius having crossdomain.xml

Hello together,
we are facing a #2170 error indicating we don't have a proper policy file in place when executing a published Xcelsius flash in SAP BI application portal.
We created a WebService that is running an SAP BI System 7.01. The WebService is function module based and was generated following the wizzard. Afterwards we created a Xcelsius app that consumes data from this WebService (via data connection). The resulting flash from Xcelsius was pulished to SAP BI System (portal).
Since there are many entries in the SDN and the internet in general we finally also created an crossdomain.xml file on the BI system which can be accessed and is visible by using "https://<server>/crossdomain.xml".
Now the confusion begins: We exported the flash from Xcelsius to local desktop and executed the corresponding HTML-file. It's working and I can receive/see WebService data (after adjusting flash-security-settings). If we upload both exported files (html and swf) to the BI system (as MIME objects) and execute the html again we are also receiving WebServervice data. So far so good. But if we execute the link from the SAP BI Portal (Xcelsius menu > SAP > Start) we still get the error #2170 indicating we don't have a proper domain policy file in place. But for my understanding we do have. So currently I would assume the error message is somehow misleading.
During all the activities I found out that this error is also raised if the user has insufficient authorization. My user has SAP_ALL authorization for testing purpose.
In general I would say we are not that wrong with our Xcelsius/WebService if we are not coming from BI portal. So my questions are:
1.) Are there any authorization on portal side that might not fit and lead to this error? If insufficient authorizations produces such an error ...
2.) Did we miss any other stuff during our try/fail-operations?
Many thanks in advance for your hints.
Steffen
