ArgoUML is a pure Java open source UML CASE tool that provides cognitive support for object-oriented design. ArgoUML provides some of the same editing and code generation features of a commercial CASE tool, but it focuses on features that enhance usability and support the cognitive needs of designers. Uses XML file formats: XMI and PGML.

Slime UML (SLIm Modelling Environment) is a slim, fast, and powerful UML plugin the Eclipse platform. It makes it simple to document Java code, reverse-engineer existing source code, and visualise complex Java libraries, even without source, as well as perform modeling with use cases, packages, and class diagrams. It features drag and drop classes and packages from the Package Explorer, automatic layout of diagrams, multiple inheritance, diagram updates when the Java code changes, exporting to Word, EMF, and SVG formats, a class diagram wizard and diagram perspective for diagram creation, and much more.
Visual Paradigm for UML is a Unified Modeling Language (UML) design tool that supports all UML diagrams, SysML diagrams, and entity relationship diagrams. Visual Paradigm for UML provides extensive use case modeling features, including full function UML use case diagram, flow of events editor, use case/actor grid, and activity diagram generation. Visual Paradigm for UML produces system documentation in PDF, HTML, and MS Word formats. A developer can design system documentation with the template designer. A system analyst can estimate the consequences of changes with impact analysis diagrams, such as matrix and analysis diagram. Visual Paradigm for UML generates Java code.
SDE for Eclipse is a UML modeling environment tightly integrated with Eclipse IDE. It lets you draw all types of UML diagrams (use case diagrams, class diagrams, component diagrams, etc.) in Eclipse, reverse source code (Java, C++, XML, XML Schema, CORBA IDL, etc.) to UML models, and generate Java source from UML diagrams. It features the latest UML notation support, a Rational Rose importer, an XMI importer, Microsoft Visio integration, HTML/PDF documentation generators, and plug-in and template support.
DB Visual Architect (DBVA) is a powerful tool that provides support for Object Relational Mapping (ORM) and Entity Relationship Diagrams (ERD), which assist with realizing UML designs as relational database implementations. By drawing a class diagram for the system, you can generate the required database tables and persistent source code for database manipulation. It can also be used with existing software.
