Hi all,
I developed a web service in Development server then I transported it to the production server. There I configured using Tcode WSCONFIG.
Again I want to use this web service in my Development server.Created a proxy. Attached Logical port in Tcode 'lpconfig' of production server. Then I write my program. Its compiled well. But when I executed it, its giving a error..
ShrtText
Access not possible using 'NULL' object reference.
I am attaching the error. At line 27 error occured...
What happened?
Error in ABAP application program.
The current ABAP program "ZWS_CUSTNAME" had to be terminated because one of the
statements could not be executed.
This is probably due to an error in the ABAP program.
Error analysis
An exception occurred. This exception will be dealt with in more detail
below. The exception, assigned to the class 'CX_SY_REF_IS_INITIAL', was not
caught, which
led to a runtime error. The reason for this exception is:
Attempt to access a component using 'NULL' object reference (points
to nothing).
An object reference must point to an object (an instance of a class)
before you can use it to access components (variable: "CUSTOMER").
Either the reference has not yet been set, or it has been reset to
'NULL' by a CLEAR statement.
