Decode an XML from WebServices

[Former Member]

Hello ! :

I need to do an application in Java. This application will receive and XML from WebServices.

But, I never did anything like that. So,I have some questions about this :

1- The webservice will return the execution of an RFC, so, how get Java this XML Code that contains the information of the parameters and tables? With tags?.

2- How i can traduce this xml code / tags, for example, to print a grid with the information received of the table parameter?

3- Will you have an example of xml that comes from a webservice or rfc?

As you can see.. i really need your help.

Sorry about my english and thanks for reading.

Bye!

Hi,

please let me rephrase it to see if I understand well:

1) at SAP side, there is an RFC-enabled function module called "RFCFM"

2) at SAP side, a web service "WsRfcFm" has been (automatically) created from RFCFM

3) You have to write a java program outside SAP, that calls WsRfcFm (that calls RFCFM)

4-a) Either you want to know how to call WsRfcFm and how the XML will look like?

4-b) or you want to know if you can call directly RFCFM?

For 4-a, here it is not a Java forum, so... About the XML, it is like any other Web service. So the data will depend on the RFC FM parameters...

For 4-b, you can also call RFCFM directly, but you need to add the Java RFC library so that to be able to communicate directly with the SAP system.

Sandra:

thanks for replying !!

you're right, the 4-a option is correct.

I know that the XML contains the structure, for example, the table returned by the RFC, but,what label contains the information? maybe something like <table> xxxxx </table> ?

Also, I read that XML only contains the structures of the parameters, So, where I receive the information that keeps the table?

Thanks again!!

Regards!

Hi,

For instance, here I have used BAPI_BANK_GETLIST. I generated a WSDL, then I did a "loopback" by generating a client proxy so that to know how to call it, started the ICF recording (SICF), tested the proxy, and I obtain that:
