When accessing or modifying webservice request or response headers in ColdFusion MX 7, you may receive an error indicating one of the following is undefined if you are using code that previously worked in ColdFusion MX 6.1:
The error will appear similar to following format:
Variable ADDREQUESTHEADER is undefined.
In ColdFusion MX 6.1, there was no mechanism to create or process header fields in webservices. TechNote 18939 provided a patch to Apache Axis to allow users to retrieve the response headers from a webservice request. This hot fix provided several useful methods to access and modify webservice header data from ColdFusion MX 6.1 via the following methods:
These specific methods were part of the hot fix and were not native CFML functions. Code that makes reference to these functions in ColdFusion MX 7 will not work because, while the equivalent functions exist as native CFML functions in ColdFusion MX 7, they exist with different names.
ColdFusion MX 7 now permits access to and modification of webservice header fields through the following native CFML functions:
Usage of these webservice functions is described in detail within the ColdFusion MX 7 documentation on using request and response headers in webservices:
