JNIPort is a Smalltalk library which allows Java code to be invoked from Smalltalk. It acts as a bridge between the world of Smalltalk objects and a Java Virtual Machine (JVM) where Java code is executing. For more information see http://jniport.wikispaces.com JNIPort 2.0 for VisualWorks can be loaded from the Cincom Public Store Repository and from the JNIPort wiki at http://jniport.wikispaces.com/Downloads JNIPort 2.0 for Pharo and Squeak is available from SqueakSource at http://www.squeaksource.com/JNIPort.html and from the JNIPort wiki. The changes from JNIPort 1.9 are: - JNIPort can now be used in Pharo and Squeak. - Packages have been renamed such that the can be shared between Store and Monticello. - Platform specific code has been moved to separate packages to make the core packages portable between VisualWorks, Pharo, and Squeak. - The much-critized _null postfix used for selectors of wrapper methods which don't have arguments is gone. - A few bugs have been fixed. Installation instructions for VisualWorks are on the JNIPort wiki, instructions for Pharo and Squeak are on the wiki of the JNIPort project page of SqueakSource. I strongly encourage you to read the instructions before installing and using JNIPort. JNIPort 2.0 has been tested with: - VisualWorks from 7.5 to 7.8 (trent dec10.3) on Mac OS X 10.6.6 and Windows XP SP 3 - VisualWorks from 7.7 to 7.8 (trent dec10.3) on Ubuntu 10.04 (64bit) with both the 32-bit and the 64-bit VisualWorks VMs - Squeak 4.2 on Mac OS X 10.6.6 and Windows XP SP 3 - Pharo 1.1.1 and 1.2 on Mac OS X 10.6.6 and Windows XP SP 3 Known issues: - In Pharo 1.1.1, you may encounter an error when JNIPort tries to register a new Java object in an internal weak dictionary. This is a bug in Pharo's implementation of this collection class. I can't do anything about it. If you can't live with it, please upgrade to Pharo 1.2. - JNIPort for Pharo and Squeak currently cannot be used with the Cog VM. - Callbacks from foreign operating system threads cannot be used in Pharo and Squeak. The Alien foreign function interface does not yet support this feature. When you run the unit tests, three tests will fail because of this restriction. These failures are expected and do not indicate bugs. Best regards, Joachim Geidel
