Due to namespace conflicts, data objects cannot be shared
between multiple service WSDLs. Different services can share data
types and, therefore the services share the definition of these
types in the WSDLs. For example, you cannot add two .NET client
assemblies that contain a
BLOB
data type to the
same .NET client project. If you attempt to do so, a compile error
occurs.
The following list specifies data types that cannot be shared
between multiple service WSDLs:
-
User
-
Principals
-
PrincipalReference
-
Groups
-
Roles
-
BLOB
To avoid this problem, it is recommended that you fully-qualify
the data types. For example, consider a .NET application that references
both the Forms service and Signature service using a service reference.
Both service references will contain a
BLOB
class.
To use a
BLOB
instance, fully-qualify the
BLOB
object
when you declare it. This approach is shown in the following code
example. For information about this code exampe, see
Digitally Signing Interactive Forms
.
The following C# code example signs an interactive form that
is rendered by the Forms service. The client application has two
service references. The
BLOB
instance that is associated
with the Forms service belongs to the
SignInteractiveForm.ServiceReference2
namespace.
Likewise, the
BLOB
instance that is associated
with the Signature service belongs to the
SignInteractiveForm.ServiceReference1
namespace.
The signed interactive form is saved as a PDF file named
LoanXFASigned.pdf
.
