Calling a local Webservice from ECC ABAP - Am I on the right track?

Hi all
In my NW2004s landscape I have an ECC system (ABAP 6.40, Java not configured/linked) and an XI system (6.40). My requirement is to call a Webservice (WS) from the ECC system.
I've converted an existing Java class (that contains 3 methods) to a webservice (WS) using NWDS. This WS has then been deployed to the XI system as it is the only one with a JAVA system. I'm able to view and test the WS methods using the Web Service Navigator on the XI system. The wsdl for the WS that was generated has the following format "http://<server>:<port>/<webservice name>/<configuration name>?wsdl (No .asmx extension as per most of the examples on SDN...not sure if this matters).
My understanding is that I should be able to create a client proxy in my ECC system (via Enterprise Services in SE80) using this wsdl and I can also configure a logical port throught txn LPCONFIG. I should then be able to utilise ABAP to call this webservice?
I've found the blog "/people/thomas.jung3/blog/2004/11/17/bsp-a-developers-journal-part-xiv--consuming-webservices-with-abap detailing this (for a 6.40 system)... but when I attempt the program I get a soap 111 error code Unallowed RFC-XML Tag(SOAP_EINVALDOC).
Am I on the right track? Is it possible to call the Webservice from ECC ABAP?
There are no dumps for me to analyse and I've also tried putting on RFC trace with no success.
Could it be that the WS is not correctly formed even though it works fine when tested from the WS Navigator on the XI system?
Thanking you in advance.

Thank you Eugene, your answer is most helpful. I supose I just wanted to do everything myself really. If when I have made my little movies, my animations and collated all my words and pictures I have problems assembling the documents then I can always get a professional to haul it together for me but I want to put in the donkey work first. I know it is a lot of money for the software but now the pain is giving way a little I'm really quite enjoying myself.
The planning which you have mentioned in your reply is of imense value I will start to do that immidiately, also the constant testing through Digital editions.
All this is really helpful and I thank you for you reply. I have made a brave attempt at some elementary annimation and posted them on youtube for testing, the urls are here if there is any interest. Basic and time consuming but I can do this much faster now.

What comes through to me from your videos is that you know your material (of course, no pun intended) and that you have a clear sense of how to present it for clear communication to, and understanding by, your audience. Without this core, no amount of professional-level visual effects will achieve your goal, a great training program.

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.

Calling an existing webservice from ABAP ?

I am trying to call an existing webservice from abap and cannot seem to get it right.
We are on 640.
What are the steps I need to follow ?
The address of the test wsdl is http://obcbox:50000/EMWSApp/DCCGen?wsdl
and http://obcbox:50000/wsnavigator/jsps/explorer.jsp?localWS=RU1XU0FwcC9zYXAuY29tJTJGRU1XU0FwcEVhci9FTVdTYXBwLmphcg%3D%3D
I need to be able to send data to the dccGenerator so it can do its work.
Any help would be greatly appreciated.
Cheers Steve.

How can I call a stateful webservice from a user-defined XPath function?

I'm calling a stateful webservice from a BPEL process using a PartnerLink which implements Custom Header Handler classes to handle the session state, storing the cookie as a property of the PartnerLink.
I'd also like to call this same stateful webservice, in the same session, from a user-defined XPath function enabling me to call this from an XSL Transformation.
Is this in any way possible? Can I access the cookie and attach it to the webservice call made by the user-defined XPath function?

Actually, as long as the servlet returns valid javascript, you can indeed "call it" from the client. It will initiate a request and return the result to the browser.
This example uses Perl, but it could be easily modified to go to a servlet instead.
Note that it is only supported in DOM browsers (IE6+/NN6+/etc)

Hi,
The HR_MASTERDATA_DIALOG might need some tweaking.. we use a custom Program on the lines of SAP's

Import local mailboxes from one account to other in the some computer

I need to import local mailboxes from one account to other in the some computer. I have tried copy/paste from one user/library to other, but mail went crazy with permission and even if I changed them manually now Mail can't save the passwords of the mailboxes, so I need enter each time Mail check the mail from the server. Any idea?

You need to let Mail do the Import, and not do this manually in the Finder. However, if you force a reindexing things may get back to normal. This assumes you are not talking about mailboxes in account folder, but rather On My Mailboxes?
To reindex all mailboxes force a reindexing by deleting the Envelope Index. With IMAP or Exchange account, forcing reindexing requires removing the account folder. See:
http://docs.info.apple.com/article.html?path=Mail/4.0/en/14019.html
Ask any questions needed to get comfortable with doing this.

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''

* On Mac you can open Firefox 4.0+ in Safe Mode by holding the '''option''' key while starting Firefox.
* On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.

Problem in calling Webservice from Webdynpro ABAP

I want to call a BAPI FM which is available in SAP ECC server when user is clicking on a button in a web dynpro application which is available in SAP Portal server.
For example,
Portal server name is DVP-EPP &
ECC server name is DVP-ECC
I have the done the following steps to achieve it,
In Server DVP ECC:
1) Created Web service from the standard BAPI FM (SE37-->Utilities-->More Utilities-->Create WebService --> From the the Func.Module)
2) Downloaded the WebService as WSDL file from SOAMANAGER
3) Tested the Web service through SE80, it is correctly calling the BAPI & creating necessary data.
In Server DVP EPP:
4) Created a Proxy class as follows,
a) SE80 --> Package --> Create --> Enterprise service
b) Selected Object type "Service Consumer"
c) Selected Service Consumer "Local File"
d) Browsed and selected WSDL file downloaded from DVP ECC
e) Selected the Package, Prefix, Request, Completed the process & Activated it.
5) Configured the Logical port as follows,
a) Selected my Proxy class through F4
b) Wrote a name for Logical port, Selected 'Default port' checkbox and selected 'Create'
c) In the next screen, in 'Call parameters' tab, selected the 'URL' radio button & mentioned the URL of the WSDL-Document created in DVP-ECC system
d) Saved the data & activated it
5) Now, tested the service through (SE80-->Package-->Enterprise Services-->Client Proxy) option.
6) When I test it, system prompts a dialog box for User-Name & Password (as available in DVP-ECC system).
After the details are given, system throws the Information message as "SOAP:14 Unexpected element -el=definitions ns=http://schemas.xmlsoap.org/wsdl/" - Exception of class CX_AI_SYSTEM_FAULT
No record is created in DVP-ECC through the WebService BAPI.
Please tell me whether the steps that I followed are correct as per my requirement and a solution for the above interruption.
Thanks in advance

Good day guys,
Somehow I managed to resolve the above error.
Now in DVP-EPP system, I am able to Test the Web service Client Proxy (through SE80) and a record is successfully created in destination system (DVP-ECC).
Now, in Webdynpro I am unable to call this webservice proxy class.
System throws the error,
Error (id=SoapFaultCode:5): Web service processing error; more details in the
web service error log on provider side (UTC timestamp 20141006045544;
Transaction ID 9A144DE49C12F1B5A6B9E41F137BE3CC)
I just created a sample WDA application and on click of a button I am calling the Webservice Proxy class as follows,
Method on_submit_click().
TRY.
      CREATE OBJECT wd_assist
        EXPORTING
          logical_port_name = 'ZLOG_PORT'. "Logic port creatd for Proxy class (in SOAMANAGER)
      CALL METHOD wd_assist->bus1240create     "Method available in generated Proxy Class
        EXPORTING
          input = ls_inp
        IMPORTING
          output = ls_outp.
    CATCH cx_ai_system_fault.
ENDTRY.
ENDMETHOD.
Do I have to do any thing additionally in order to call the WebService in WDA?? Because, in the same system, if I test it in SE80, record is perfectly created in destination server.
Also please suggest if I have to do any other configuration changes related to this.
Keenly awaiting your reply.
Have a nice day .
Thank you.
