TJI has an extensive feature list while being fully integrated and very easy to navigate.

TJI is 100% Java and works on all platforms with JDK 1.3 or higher. Java Guru standalone version also requires Java 1.3 or higher. However, more feature-rich versions are available for Java 1.6 and higher.

There are many example projects available on our resources page, including 'SwingSet2' and 'Duke's Book Store'. Each project downloads as one zip file which can be 'imported' in one simple step, ready to run.

TJI includes an extensive set of guides to the Java language and object oriented programming. These guides are a core part of TJI (and also available on-line). All the example programs can be quickly downloaded as TJI projects from our resources page.

These guides cover the whole range - from the simplest 'Hello World' program, through Turtle Graphics, applets and GUI building with Swing, to an understanding of object oriented terminology and design.

More advanced subjects are also covered, including database programming with JDBC and SQL, and web applications using servlets and JSP.

Use of UML is entirely optional in TJI. However, if you wish to use UML, you can switch between source code view and UML view whenever you like.

You can start a new design in the UML view, in which case the source code for the UML model is written for you, or view in UML an existing project. You can make changes in either view - the two views are automatically kept in synchronisation.

Note that TJI's UML functionality is restricted to class diagrams, but its automatic drawing of these diagrams makes using UML a simple and fast process.

We appreciate all suggestions for improvements and new features, no matter how small.

We aim to fix any bug within a few days (usually within 48 hours) and make that fix available to all immediately.

Simply complete this simple form to send us your feedback (whether you are an existing customer or not).

Because TJI is so easy to use and provides plenty of help on the Java language and Object Oriented design, it is the first choice for the teaching environment.

TJI has an integrated Turtle Graphics functionality that provides a gentle introduction to computer programming.

TJI allows a design to be developed in UML in a straightforward manner. Students can switch between UML and code view at any time as the two views are automatically updated.

There are plenty of examples to help students grasp the basics and apply these to their own designs.

Students can go on to learn how to program web applications with servlets, JSP and databases with the minimum of fuss - and all within the same environment because TJI has both an integrated Webserver and Database Manager (including a JDBC implementation).

TJI allows multiple users to create their own workspace where individual preferences and project files are stored.

TJI allows you to easily develop database applications using its integrated database with a DBMS and JDBC driver - and a graphical database manager.

There are several example projects available from our resources page. One demonstrates the creation of tables, insertion of data and obtaining a result set using SQL. A second illustrates using a database with JSP and HTML forms.

Web applications are an exciting field for programmers to work in - and the skills required are in great demand.

TJI includes all the servlet and JSP packages in its single jar file download, so even if you don't have the 'enterprise edition' Java development kit, you can still develop servlet and JSP programs with TJI.

TJI has its own integrated web server and web browser - and even its own database. So TJI has everything you need to learn and write programs in all these areas.

TJI's 'Smart Server' technology allows you to ride the edit, compile, run cycle without ever needing to manually start the server, reload servlets and JSP pages, or delve into log files to discover run-time exceptions. Our 'Smart Server' technology reloads server code automatically, and indicates the location of run-time errors in your source code.
