Importing Java projects

• Start by selecting “File → Import…” in the Eclipse menu.
• Select “Jar2UML Import → Import Java projects to UML Models” and click “Next”.
• The Jar2UML Import Wizard dialog appears.
• At “Enter or select the parent folder”, select the folder in the workspace where you want to save your UML model. This folder must be – or reside in – a Java project!
• At “New File Name:”, choose a file name for your UML model.
• If the UML model already exists, a warning is displayed, and an option to update the existing model becomes available. Check the option to keep the existing UML model and update its contents. Leave the option unchecked to overwrite the UML model.
• If you don't want to include any referenced projects and jar files in the Eclipse workspace, then uncheck the “Include referenced projects and jar files in workspace” option.
• If you don't want to import operations and attributes, then uncheck the “Include operations and attributes” option.
• If you only want to import packages starting with “java”, “org.omg”, “org.ietf”, “org.w3c” or “org.xml”, then select “Only Java API packages”. You only want this when reverse engineering the Java class library itself!
• By default, only named public and protected elements are imported. To include all elements, select “Include anonymous and private elements”.
• Jar2UML has to introduce references to dependencies in the UML model to provide an accurate model of the jar file. If you want Jar2UML to exhaustively search for dependencies in the bytecode instructions themselves, select “Include elements referenced by bytecode instructions”.
• Click “Finish” to create the UML model from the selected jar files.

If you also have UML2Tools installed, you can right-click the generated UML model and select “Initialize …_diagram file” to create a visual representation for the UML model.
