Accessing Rational Rose from Java

 Java/J2EE COM Interoperability Products Page

This example demonstrates how to access Rational Rose from Java. J-Integra® for COM is a Java interoperability component that bridges Java and Rational Rose. It provides bi-directional access of Java objects and COM components. 

/* 
 * This example shows how you can access Rational Rose running under MS Windows from a 
 * pure Java client running on any operating system that supports a standard JVM, by 
 * using the J-Integra® pure Java-COM bridge (see http://j-integra.intrinsyc.com/). 
 * 
 * The program takes as a parameter a Rose model and from this model it creates an 
 * HTML file listing all the classes as an index with reference to their descriptions,  
 * and operations. 
 * 
 * To run this example, create a 'rose' subdirectory, and run J-Integra®'s 'com2java' 
 * tool, specifying the Rose type library (RationalRose.tlb from the Rose installation 
 * directory) as the input type library, 'rose' as the package name, and the rose subdirectory 
 * you created as the output directory. 
 * 
 * This Java client will run on any machine which has a standard JVM, such as a UNIX machine. 
 *
