Japanese Technotes
For the convenience of our Japanese developers, many of our Technical Notes have been translated into Japanese.

Mac OS TN1158: Levatatus Interruptus By George Warner The use of floating point instructions is usually handled by a development system's libraries. One special case not properly handled by these libraries is the saving and restoring of the volatile floating point registers for interrupt routines. Floating-point assembly code will need to be written for this case. This Technote will address this topic. TN1157: Don't println to a Socket By Jens Alfke A common cause of deadlocks in client-server Java applications when running on Mac OS stems from improper use of the println method when writing to an OutputStream connected to a Socket. Here's why, and what you can do about it. TN1156: Scribbling Into AWT Components By Jens Alfke This Technote describes how to draw into an AWT Component by means other than the Java AWT Graphics API. In particular, by discovering the QuickDraw GrafPort, origin, and clipping Region corresponding to the Component’s visible area, you can use any means at your disposal (most likely QuickDraw) to draw things inside the Component. TN1155: JNI Tips: Building Your Native-Method Libraries For MacOS By Jens Alfke JNI (Java Native Interface) is a cross-platform standard for implementing Java methods in native code. MRJ 2.0 and 2.1 support JNI; however, some developers run into trouble getting their JNI libraries to work correctly on Mac OS. For the most part these are build- and installation-related issues. This Technote is designed to put you at ease. TN1154: Debugging Java Code With MacsBug By Jens Alfke MacsBug, the low-level debugger for the Mac OS, seems unlikely to be useful for debugging a very high-level language like Java. Au contraire! The MRJ plug-in 'dcmd' for MacsBug adds a number of commands that can help you debug everything from deadlocks to memory leaks. This Technote introduces MacsBug for those not familiar with it, and shows how to use the MRJ commands to debug your Java code.

In addition to our recent Technical Notes, all previous Technical Notes are also available. A quick, easy-to-scan Table of Contents includes all of these Technical Notes in an itemized list sorted by date published on the Web. A more robust Table of Contents, which includes a descriptive passage on each Technical Note, is also available.
