No cockpit has been specified within the URL.
In beta versions of the NWBC runtime, the usage of a cockpit within the URL was enforced. When calling NWBC with the URL /sap/bc/nwbc, an exception was raised to indicate that no cockpit is available. This error is always an indicator that the ABAP system is at a level that is not supported.
See INSTALL.03 On which SAP NetWeaver Versions is NWBC v3.0 supported?and update the service pack level to a minimum level supported.
