The following table is a mapping between Java types and Tuxedo parameter types required by a Tuxedo service. Use the appropriate Java types for the value of the DataSet or ServletDataSet. If you specify any parameter as a Java String, it is translated automatically to the appropriate type according to the service definition in the Metadata Repository.

This feature is also used to convert all data inside an HttpServletRequest object, because all parameters associated with the request are represented in string format. Otherwise, use the type specified in the table below. Providing the correct data type may improve efficiency because no lookup is required to convert from a string.

A Tuxedo CARRAY is specified in a Java string by describing each byte value as a two-digit hexadecimal number. You specify multiple bytes by concatenating these hexadecimal digit-pairs together. For example, the string "FF0A20" would represent the Tuxedo type CARRAY {255,10,32}.
