How to access HTTP headers while exposing or invoking WEB Services in BusinessWorks 6.X and BusinessWorks Container Edition
While exposing or invoking WEB Services it is in some cases needed to access standard or custom HTTP headers. In BusinessWorks 5.X there was no other solution than developing an HTTP Proxy but this is no longer the case in BusinessWorks 6.X and BusinessWorks Container Edition.
To get or set HTTP headers while exposing or calling WEB Services you have to do the following:
Create an XML schema to manage your context
Using the tool of your choice create an XML schema containing the elements you want to use to set or get HTTP header values.
Define the context in the BusinessWorks process exposing or invoking the WEB Service
Depending on what you want to do select the Component or the Reference that needs HTTP headers to be accessed.
Open the Context tab and set the Input Context or Output Context or both as needed.
Note : it is possible to use the same context for all operations or a specific context for each operation (click on the yellow pencil icon for this).
Set or Get the context in the BusinessWorks process
Add a Set Context or Get Context activity, or both, in the process and map inputs has needed.
Map the header fields in the SOAP Service Bindings
Then select the Component corresponding to the target process Component or Reference and open the ‘Bindings’ tab and map the Headers using the Request Context or map the Response Context using the Headers or both as needed.
Note that it is possible to access standard HTTP Headers and also custom HTTP Headers as shown in the example above.
