9.2.2 Data types
The gateway functionality can send and receive data types that can be specified in IDL.
The in attribute is the only argument that can be specified in the EJB remote interface. You can use only Java arrays and classes for which the Serializable interface is implemented as structure types that can be used for arguments and return values. Java-provided objects cannot be handled as communication data.
When you issue requests from OTM, take account of the handling of the string and char types. Note that IDL code generation commands provided by CTM generate IDL code that can be used in OTM. For details about the handling of the string and char types, see 9.3.2 Handling characters and strings in OTM. For details about IDL, see the manual TPBroker Object Transaction Monitor Programmers Guide.
