Transaction code to create virtual interface.

Former Member — Wed, 14 Dec 2005 06:28:14 GMT

I want to create a web service from a RFC. For that first, virtual interface needs to be created which will be linked to the RFC. Can u please tell me what is the transaction code to create a virtual interface.

hi,

Using SE37 the function must be 'RFC Enabled'. Then select the menu 'Utilities -> More Utilities -> Create Web Service'. Name the virtual interface, select the function module as the endpoint. The web service must still be enabled in some way through transaction SICF.

You can test the web service using tcode WSADMIN.

regs,

Thankx for ur reply.

Now I have created the Web service. To do this I have done the followings-

1. created one RFC enabled Function Module.

2. Created one virtual interface

3. Created Web service defination.

4. Released Web service from the wsconfig transaction.

Then from The transaction wsadmin I have opened the browser by clicking Web Service > Web Service Homepage (from menu)

After logging in it , shows the web service and RFC with in it. Now after clicking the Test link from the browser it asks for the parameter of the RFC. But After populating the parameters and clicking send button. it gives NullpointerException.

exact err message is --

An error has occurred. Maybe the request is not accepted by the server:

java.lang.NullPointerException
