SAS 9.3 BI Web Services
no longer includes a .NET version. The benefit of Web services is
that the technology of the server does not matter to the client. Because
of differences in the underlying technologies between previous .NET
and Java versions of SAS BI Web Services, the format for input and
output messages differed significantly between the two products. This
meant that clients created for one version were typically not compatible
with the other version. To encourage interoperability and further
innovation in SAS BI Web Services, SAS 9.3 does not include a .NET
version.
SAS 9.3 BI Web Services
for Java is fully backwards compatible with both the Java and .NET
versions of SAS 9.2 BI Web Services. When you perform a migration
using the SAS Migration Utility and the SAS Deployment Wizard from
SAS 9.2 to SAS 9.3, any generated Web services are also migrated.
If the generated Web service being migrated was created with SAS 9.2
BI Web Services for .NET, the migrated SAS 9.3 version is fully compatible
with clients that were created for the SAS 9.2 .NET version. The migration
process sets a flag on the generated Web service metadata that Web
services can use when generating and displaying the WSDL and processing
a Web service invocation. You need to modify only the endpoint of
the generated Web service in the client code to point to the new endpoint
in the migrated system. You can retrieve the new endpoint of the migrated
service by using the SAS Configuration Manager or by locating the
Web service in
/System/Services in
SAS Management Console.
If you regenerate a
Web service that was migrated from a .NET installation, then the Web
service is no longer compatible with clients that were previously
created. You can force .NET backwards compatibility by passing the
dotnetMode=true query parameter when retrieving WSDLs
and invoking Web services. For example, to retrieve a .NET-backwards-compatible
WSDL file, use a URL similar to
http://host:port/SASBIWS/services/yourServiceName?wsdl&dotnetMode=true. To invoke the Web service, send requests to the endpoint
http://host:port/SASBIWS/services/yourServiceName?dotnetMode=true.
