Depending on the data mappings used in your application, exceptions other than rwsf::Exception may be thrown. For example, for services generated with default mappings and with the -STL option, message text is returned for exceptions derived from std::exception and rwsf::Exception, so you should be prepared to catch these exceptions. For -sourcepro generated services, message text is returned not only for std::exception and rwsf::Exception but also for RWxmsg, so there will be three types of exceptions your application will want to handle.

If you are using any custom datamapping via the -datamap option when generating code, you may have other exceptions that should be caught. For more information on this option, see “Creating Customized Mappings,” in the HydraExpress XML Binding Development Guide.
