Processing With Module Definition Files

This method of SQLJ processing, which can be activated in SQL/MX Release 2.x by

using the -createMDF option on the command line or in a properties file, generates

module definition files (.m files) in addition to extended profiles. The SQLJ translator

program, sqlj.tools.Sqlj, produces a module definition file during customization

and automatically SQL compiles the module definition file by invoking the SQL/MX

compiler to produce a module.

Processing an SQLJ program with module definition files involves these steps:

1. Creation of the SQLJ Source File on page 1-11

2. Translation on page 1-11

3. Compilation by the Java Compiler on page 1-12

4. Customization With Module Definition Files on page 1-19

5. Compilation by the SQL/MX Compiler (MXCMP) on page 1-19

For the entire process, see Figure 1-3 on page 1-18.

The first three steps of creating, translating, and Java compiling an SQLJ program are

the same as if you had chosen to process the SQLJ program without module definition

files. For more information, see Default Processing Without Module Definition Files on

page 1-9.

The last two steps of customization and SQL compilation, however, differ from the

default method of processing an SQLJ program without module definition files.
