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.

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.

How To : Call External Webservice from BPEL and pass SOAP Message to the WS

Hello All-
Greetings to all BPEL gurus. I am currently facing difficulties in calling an External Webservice from my BPEL Process and passing SOAP Message to it. The details are below:
1. The BPEL process, using database polling feature of DB Adapter, will get the records from the database.
2. Transform the message
3. Call the External Webservice and pass the transformed message as the input to it. However the Webservice expects the BPEL process to send SOAP headers in the input message.
I am struggling on how to put the transformed message within a SOAP envelope in the BPEL process.
If anyone had similar requirements and have successfully been able to send SOAP messages from BPEL process to an external webservice, kindly let me know.
Also if there is some kind of documentation or any link in the forum that I can refer, please let me know that as well.
I am new to Webservice integration using BPEL and would really appreciate your help.
Thanks In Advance

Dibya

Hi Dharmendra,
I am trying to send a SOAP message from my BPEL process to a web service. I have a complete SOAP message in a complex variable defined in the wsdl for the partnerlink (web service). My problem is that when I invoke the partnerlink it fails even though the content shown in the BPEL console looks valid.
I have set up obtunnel to see what I am actually sending out from BPEL. You mention that BPEL creates the SOAP envelope automatically.
I think that my problem is a result of this automatic SOAP envelope that BPEL is creating. Do you know if there is a way to turn it off?
This is what I see in the TCP monitor, please note the double SOAP env:Body:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <env:Body> <RCMR_IN000002NR01 xmlns="urn:hl7-org:v3" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsa="http://www.w3.org/2005/08/addressing" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">
<env:Header>
<wsa:To xmlns:wsa="http://www.w3.org/2005/08/addressing">http://testhost/CCS/Service_Endpoint</wsa:To>
<wsa:From xmlns:wsa="http://www.w3.org/2005/08/addressing">
<wsa:Address>http://localhost/CCS/Service_Endpoint</wsa:Address>

<env:Body>

</RCMR_IN000002NR01>
</env:Body>
</RCMR_IN000002NR01>
</env:Body>
</env:Envelope>
Any help is appreciated.

Aagaard

Should have mentioned. I am using BPEL 10.1.3.4
Edited by: Aagaard on Oct 31, 2008 8:43 AM
I have opened a new thread for this question so as to not confuse the issue more than necessary.
How many SOAP envelopes do you really need?

How to call java bean from jsp

hi
How to call a java bean from jsp page..
Is any other way to call javabean from jsp page apart from this sample code...
<jsp:useBean id="obj" class="com.devsphere.articles.calltag.TestBean"/>
thnx in advance

If you also use servlets, you can attach beans to the request or session and use them directly in your JSP's. So if you do:
request.setAttribute("name", yourBean);and then forward to a JSP, you can reference the bean like:
${requestScope.name}

How to call class file from jsp without creating packages

i m using tomcat 5.5

i got some error.

i m using tomcat 5.5
i stored my class file into WEB-INF\Class directory
how to call that class file. from my jsp page.
i got some error.
i used package concept,that works fine.Then use packages.
As of Java1.4, you can no longer import classes from the default package (no package declared) into classes that are packaged.
All Tomcat classes are in packages, including the compiled JSP.
Therefore: Your classes need to be in a package inorder to be imported and used by the JSP.
Why the problem? If you know it works with packages, why try not to use them?

How to call RDF report from JSP page

Can anyone help me out in this case. Is there any tag or procedure or any other way by of that i can perform this work.

Hi Ashok,
You can use rwservlet - nothing really to do with JDeveloper. Once you have report server up and running (hint: read http://download-uk.oracle.com/docs/cd/B14099_19/bi.1012/b14048/toc.htm), you can call a report like this:
http://server:port/rwservlet?report=my_report.rdf&destype=cache&desformat=html&p_my_parameter=xxx etcHope this helps,
John

WLS 7.0 : How to call a webservice from a webservice, both running on a same server?

Server settings :
Two webservices running on a server.
WEB-INF\lib contains the respective XXX_client.jar files.
One webservice calls another one using service Port and gets the Exception NoClassDef...
How to resolve?

It seems that there is no answer to my problem stated below
"Archana Padhye" <[email protected]> wrote:
>
Before putting the stack trace I should supply more information.
There are two webservices viz. Trigger and Proxy
Trigger needs the Proxy_client.jar in its classpath at the time of building
the
Trigger webservice.
The server classpath doesn't have this particular jar.
So the Exception is about not finding the class for the service.
If that jar is added in the classpath, there is error at server startup
since
the method signatures mismatch.
Having client jar in the classpath is not the way, I assume.

Hi,
You have not said if your servlet is in a package in which case which one.
you need to add the '/servlet/' to the href so it becomes

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
