JNIPort preview for Pharo available on SqueakSource
I have made a preview release of JNIPort for Pharo/Squeak available on SqueakSource: http://www.squeaksource.com/JNIPort.html 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. If you want to know what can be done with JNIPort, see http://philemonworks.wordpress.com/2010/04/29/google-api-access-from-smallta lk-using-jniport/ for an example. Installation instructions are on the Wiki at SqueakSource. See http://jniport.wikispaces.com/ for more information about JNIPort. The current state of the Pharo/Squeak version of JNIPort (as of 7 June 2010): * Callbacks from Java to Smalltalk are not yet supported. * In contrast to VisualWorks and Dolphin, JNIPort does not create ghost classes as wrappers for Java classes, but creates ³real² classes which can be seen in the system browser. It also does not copy prototypes of CompiledMethods when a wrapper class or a Java class is created, because this causes VM failures in Pharo 1.0. Instead, methods are compiled from source code. This has a performance impact, of course. * Another difference from the VisualWorks and Dolphin versions is that wrappers for Java methods without arguments don¹t have selectors ending with an awkward ³_null² suffix. * JNIPort has been developed and tested with Pharo 1.0 on Mac OS X 10.6.3. If it works in Squeak and on other operating systems has yet to be tested. * I have briefly tested JNIPort with Pharo 1.1 beta 11367, but this needed some manual modifications of Alien  without them Alien causes problems in Pharo 1.1. * In Pharo 1.1, starting a JVM needs 11 seconds vs. 4 seconds in Pharo 1.0. I don¹t know yet why. * I don¹t have a Metacello configuration yet. The next steps will be: * Adding support for callbacks from Java to Smalltalk. * Testing it on more platforms. * Reorganization of the documentation on the JNIPort wiki, and addition of Pharo/Squeak specific documentation similar to the documentation for the VisualWorks version. * Release of JNIPort 2.0 for VisualWorks and Pharo/Squeak when everything is stable. This will be after the release of Pharo 1.1. If it works in Squeak 4.1 or on Linux or Windows, please let me know, especially if you had to do something which might be worth mentioning in the installation instructions. Have fun with JNIPort, and let me know if it works! Joachim Geidel

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.
If you want to know what can be done with JNIPort, see

Installation instructions are on the Wiki at SqueakSource. See http://jniport.wikispaces.com/ for more information about JNIPort.
The current state of the Pharo/Squeak version of JNIPort (as of 7 June 2010):
- Callbacks from Java to Smalltalk are not yet supported. - In contrast to VisualWorks and Dolphin, JNIPort does not create ghost classes as wrappers for Java classes, but creates ârealâ classes which can be seen in the system browser. It also does not copy prototypes of CompiledMethods when a wrapper class or a Java class is created, because this causes VM failures in Pharo 1.0. Instead, methods are compiled from source code. This has a performance impact, of course. - Another difference from the VisualWorks and Dolphin versions is that wrappers for Java methods without arguments donât have selectors ending with an awkward â_nullâ suffix. - JNIPort has been developed and tested with Pharo 1.0 on Mac OS X 10.6.3. If it works in Squeak and on other operating systems has yet to be tested. - I have briefly tested JNIPort with Pharo 1.1 beta 11367, but this needed some manual modifications of Alien â without them Alien causes problems in Pharo 1.1. - In Pharo 1.1, starting a JVM needs 11 seconds vs. 4 seconds in Pharo 1.0. I donât know yet why. - I donât have a Metacello configuration yet.
The next steps will be:
- Adding support for callbacks from Java to Smalltalk. - Testing it on more platforms. - Reorganization of the documentation on the JNIPort wiki, and addition of Pharo/Squeak specific documentation similar to the documentation for the VisualWorks version. - Release of JNIPort 2.0 for VisualWorks and Pharo/Squeak when everything is stable. This will be after the release of Pharo 1.1.
If it works in Squeak 4.1 or on Linux or Windows, please let me know, especially if you had to do something which might be worth mentioning in the installation instructions.
Have fun with JNIPort, and let me know if it works!

The problem with the Moose and reasoning about Java thing (I think this is what you are thinking about) is to keep the importer maintained, as Doru convinced me. In the end the infusion way works OK for me, so right now I am not looking for another solution. If one presents itself I am happy to give it a try :-) On 08 Jun 2010, at 11:13, Stéphane Ducasse wrote:

Hi Johan, It is not only reasoning about Java. A connection to Java is very useful to communicate with Java libraries (for example, graph libraries). Also, what Johan Brichau did in VW was to directly query Eclipse for reasoning about Java. Pretty cool :) Cheers, Doru On 8 Jun 2010, at 23:27, Johan Fabry wrote:

True, I was just considering my point of view because my name propped up :-)

Yes, penumbra is very cool. We used it in the first version of AspectMaps built on VW. Penumbra is what I wanted Irish to be in my time, but at that time Eclipse did not have sub-method granularity for the Java code. The difficulties with the penumbra way is that Eclipse is a horrible beast to work on because of its complexity (I have some nice plugin horror stories). So Respect to JohanB for getting it working in the first place, and I understand why there is nothing like this for Pharo (yet). -- Johan Fabry jfabry@dcc.uchile.cl - http://dcc.uchile.cl/~jfabry PLEIAD Lab - Computer Science Department (DCC) - University of Chile
