To represent text data, Java programs always use the Unicode character
set, while CICS TS programs use EBCDIC. When a Java program or enterprise
bean calls a CICS TS server program, any text values in the communications
area of the server program must be converted from Unicode to EBCDIC on input,
and from EBCDIC to Unicode on output. The enterprise bean in the EJB Bank
Account sample uses the CCI Connector for CICS® TS, which handles this data conversion automatically—see
Data conversion and the CCI Connector for CICS TS.
Note: Only the text data returned by COBOL program
DFH0CSTD is converted from EBCDIC to Unicode . (No conversion is necessary
for server program DFH0ACTD, nor on input to DFH0CSTD, because there are no
text values in the communications areas.)
