CICS web services - use of COMP and COMP-3 Cobol fields into WSDL with a soap interface

We have a CICS application hat we intend to use without modifications with a CICS web service.  In the DFHCOMMAREA there are COMP and COMP-3 fields,  when generating the WSDL they are defined as short but this causes an Execution error : file 'CAS0CWSU'
error code: 114, pc=0, call=1, seg=0
114 Attempt to access item beyond bounds of memory (Signal 11) .  Are these data types supported and if yes how to describe them?  Thanks
