Transforming UML models into Java code

Use the UML-to-Java transformation to create a Java™ project from Unified Modeling Language (UML) specifications and to generate Java code from a UML model.

Important: The UML-to-Java 1.4 transformation is deprecated, and is now called the UML-to-Java (deprecated) transformation. No functionality is being added to the UML-to-Java (deprecated) transformation, and the transformation behavior is different from the UML-to-Java 5.0 transformation, which is now called the UML-to-Java transformation. You should use the UML-to-Java transformation, whether an application contains code that is compatible with Java 2 Platform, Standard Edition (J2SE) 5.0 or J2SE 1.4 or later.

Java transformation profile
The UML-to-Java transformation profile contains several stereotypes that you can apply to validate elements in the source model, and stereotypes that control how the transformation generates Java code.
Applying the UML-to-Java transformation profile
You can apply the stereotypes in the UML-to-Java transformation profile to validate source model elements, or to control how the UML-to-Java transformation generates Java source code.
Specifying exceptions in UML operations
To represent Java exceptions in a UML model, you can specify UML classes in the RaisedException property of a UML operation. When you run the UML-to-Java transformation, the transformation creates a Java method that corresponds to the UML operation. The method signature contains a throws statement that contains the class or classes that you specify in the RaisedException property.
Setting preferences for UML-to-Java transformations
You can specify whether the transformation displays a warning message before replacing source UML model elements with pointers to the generated elements.
Creating or editing UML-to-Java transformation configurations
To generate output such as code from a source model, or to generate a model from code, you can run a transformation. To run a transformation, you must create a transformation configuration. A transformation configuration specifies information that a transformation requires to generate the expected output.
Running and rerunning UML-to-Java transformations
You can run a transformation on an entire UML model or on a subset of model elements to generate output such as code. When you rerun the transformation after you change the source model or the generated code, you must identify the sections of generated code that you do not want the transformation to overwrite, and then protect them. Rerunning a transformation involves the same steps as running a transformation for the first time.
