DrJava is an integrated Java development environment that supports interactive evaluation of expressions. It is available for free, and it is available under an open source license (GPL).
On Mac OS X, the DrJava Mac application is a better choice than the jar file because it wraps the jar file in a 'Mac app' that conforms to the user-interface conventions of the Mac platform. To install DrJava: If you have not already installed a Java SE Development Kit (JDK), version 5 or 6, downloadand install one from the Sun Microsystems.

DrJava for Mac is a lightweight development environment for writing Java programs. It is designed primarily for students, providing an intuitive interface and the ability to interactively evaluate Java code. It also includes powerful features for more advanced users. The tool is available for free under the BSD License, and it is under active development by the JavaPLT group at Rice University. DrJava requires a Java 2 v1.4 or later virtual machine. (Note: The JDK, not the JRE, must be installed to have access to compilation in the app.) If you need to download a JVM, we recommend Sun's JDK 5.0 for Solaris, Linux and Windows. Other users should use the Java virtual machine that comes with their operating system (including macOS). Also, DrJava for macOS uses two Java Virtual Machines (one for the main program, and one for the Interactions Pane) that use Java's Remote Method Invocation (RMI) to communicate with each other. RMI uses TCP/IP as the default transport mechanism, so you must have those drivers installed. Without TCP/IP, Dr Java will not start properly. Also Available: Download DrJava for Windows

hi, i have been using drjava for a while and i am pretty happy with its interface and overall preformance. drjava compiler is using verstion 1.4.x however i would like to change that to 1.5 which is installed on my machine. i am writing codes that takes advantage of new classes in 1.5 and it does not compile via drjava (compiler v.1.4.x) however through terminal which is set to compile via 1.5 version, those codes compile and work just fine! i looked at drjava preferneces but i see no options to change the compiler version? by the way i am using mac os x tiger, drjava version 20050814-223. thanks for your help in advance.

Install Drjava
I've just downloaded 'drjava-stable-20050814-2234' and started the App 'DrJava.app' - closed it again - and I got a '.drjava' file in my home dir. My default java version is 1.5 !! Therefore I then modified the '.drjava' file as described in the user guide. added this line: 'javac.location=/System/Library/Frameworks/JavaVM.framework/Versions/1.4/Classes/classes.jar' I then reopened 'DrJava.app' - and I got both Compiler 1.4.x and 1.5.0 You should also be able to add the new java.location via the GUI under 'Resource Location->Tools.jar Location' Rene [ November 17, 2005: Message edited by: Rene Larsen ]

alright i came up with a solution. i was under the impression that spotlight searches for the hidden file as well. i used thinkertool utility to identify .drjava file which was located in my home directory. the instructions in the documentation is not very clears on how exactly change the compiler version! instead, i used the java preferences utility located in /Applications/Utilities/Java/J2SE 5.0/. from there i just had to change the order of java verstions that appls used in my system. before it was set to 1.4.2 then 1.5. now the order is the other way around and everything is working great.

Actually, I've found that if I just set the Java Applet and Application Runtime settings to J2SE 5.0 in the Java Preferences.app in /Applications/Utilities/Java/J2SE 5.0, DrJava will use 5.0 on it's own. However, this is interesting because I would love to use DrJava to compile LeJOS code, and if possible I'd like to get DrJava to include the LeJOS Compiler in the compiler list. BTW, I love DrJava for a Java development IDE on the Mac. It is powerful yet easy to learn and use. http://drjava.org/ [ December 02, 2005: Message edited by: Scott Spencer ]
