error while consuming Web Service (returning XML ) in ABAP

[Former Member]

Hi,

i am trying to consume a web service in ABAP. ( webservice which takes a request and return a XML string back).

I created a proxy class in SE80. and i tested it successfully.

When i tried to use the class in my program, it is giving dump.

i am not sure what is the problem. I guess it is not able to handle null values in XML.if that is the case. how to handle it..

whats the dump analysis says , give us some more info on the dump from st22

The dump says:

Runtime Errors OBJECTS_OBJREF_NOT_ASSIGNED

Except. CX_SY_REF_IS_INITIAL

Error analysis

An exception occurred that is explained in detail below.

The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not

caught and

therefore caused a runtime error.

The reason for the exception is:

You attempted to use a 'NULL' object reference (points to 'nothing')

access a component (variable: "LO_CLIENTPROXY").

An object reference must point to an object (an instance of a class)

before it can be used to access components.

Either the reference was never set or it was set to 'NULL' using the

CLEAR statement.

I think this dump is because of the default value ( space) in some elements. How to avoide that.

wheni catch CX_SY_REF_IS_INITIAL it is not giving any dump. But this is not my requirement. Because it is not getting anything into response string.

sorry friends...

my guess is wrong. the dump is not becaus of default value in some elements.

I tested with XML which return some value in all elements. Even then it is giving the same dump.

I am totally stucked. Can help please.
