    Question about academic license

    Thanks for your answers. Please apply for a free license when your project is ready for a public release. We would also write about it in our blog to help it gain some popularity.

    Question about academic license

    Excelsior-Jet would allow organizations using JUIBrowser to deploy the runtime to a shared-folder - and therefor would allow to run it without any 3rd party software installation. An app-private JRE is not really well suited for this task, because of the large working set which has to be transmitted over network.. So the code running on the client is the same regardless of the application, correct? If yes, it indeed makes sense to precompile it. However, a ULC app may run as either applet or JNLP app, but Excelsior JET does not support either. How would your end users launch their apps?

    Support for Jre, SE 1.4.2_02

    Excelsior JET 4.8 was the last version with J2SE 1.4.2 support. We still have it available for purchase. If your app does not work on Sun JRE version 5.0 nor 6, but works on 1.4.2, we could provide you with a trial package of Excelsior JET 4.8. But you won't have the latest features introduced in Excelsior JET 5 and 6...

    Question about academic license

    Sure Its a framework called (at least for now) JUIBrowser. Its some kind of remote-interface-interpreter, which means you can run swing-like code on the server, however the server just creates an UI description and sends it down to a small client which interprets the result. Very much like SAP interfaces, but much more flexible. So is it something like Canoo ULC (Ultra Light Client)? Where does Excelsior JET fit in your framework?

    Question about academic license

    I am not sure. My project is not one of those show-case projects, it has not even really started up with many users, which is stated as requirement for the free non-commercial license. I have not decided yet, but would the academic license also be allowed to use for this case? Would you mind telling us a bit more about your project so that we could advise you better? It is a bit difficult to judge without knowing any details.

    Usage in Open Source

    You mix compilation and distribution. Simply put, GPL permits you to do whatever you want with the source code, the restrictions are on distribution. You may only redistribute GPL apps compiled with VC++ if you link to the VC++ runtime dynamically. The Excelsior JET Runtime contains our proprietary code and Sun code licensed under SCSL Commercial Use, which is not GPL-compatible.

    Question about academic license

    First of all, the Excelsior JET Runtime license is not GPL-compatible. LGPL, BSD, CPL, and many other open-source licenses are all fine, but not GPL. If you own the copyright, you may dual-license your project or change the license. The free non-commercial license would be more appropriate. Yes, absolutely. No. Yes, it has all features of the Professional Edition, only the license is different. If you break all links with the academic environment, the executables will remain legal, but you must stop using the Academic Edition. Thanks.
  8. Can you reduce the problem module to the smallest piece of code that still exhibits the error and post it here?

    How do I suppress the warnings?

    From our previous porting/migration efforts, I would suggest you to switch warnings off one by one, and only after reviewing the respective pieces of code. Warnings may indicate problems. Even if there is one real problem for 100 warnings, debugging it with warnings disabled is likely more expensive than reviewing all warnings.

  16. We have released Excelsior JET 6.0, featuring the long-awaited support for Java SE 6. Other news are: - support for Windows Vista and RHEL 5, - support for version information and post-install actions, added due to popular demand, - Difference Tracker in JetPackII to help you create updates, and, as usual, - application performance improvements. Full information on new features and improvements Download Excelsior JET 6.0 Evaluation Package
  17. snowman

    Usage in Open Source

    No, it is not. The evaluation license does not allow redistribution. And in any case, the evaluation package produces executables that time out on a fixed date. We do grant free licenses to authors of non-commercial Java apps (not necessarily open source) in return for some promotion for our product. However, the Excelsior JET runtime license is not GPL-compatible. You would have to change the license for the natively compiled version, which is only possible if you own the copyright for all GPLed pieces code in your app. LGPL is ok, as well as many other open source licenses. Please feel free to email our Sales Dept. with more questions.

    Apple OS X Support?

    Dave, I regret we cannot promise the Mac OS X version to become available any time soon. I am sure however that your Windows users would appreciate that huge benefit you are mentioning. Dmitry
  19. New Maintenance Packs are available for all four Excelsior JET 4.x releases: Excelsior JET 4.0 Maintenance Pack 3 Excelsior JET 4.1 Maintenance Pack 2 Excelsior JET 4.5 Maintenance Pack 4 Excelsior JET 4.8 Maintenance Pack 3 Please refer to the Release Notes sections on the above linked pages for details.
  20. Given the broadness of your question, I could say that we are working on it right now. However, that is going to be a custom Modula-2 compiler targeting a CPU architecture other than x64, and an operating system other than Windows or Linux... Then, the core components of Excelsior JET, namely the AOT compiler and the JVM (except the fast JIT compiler), are written in Oberon-2 and Modula-2 respectively. So if we ever decide to do a 64-bit version of Excelsior JET, we would have to either convert the runtime to C++ or retarget XDS Modula-2 to x64. In that sense, there is a chance that there will be Native XDS-x64. However, the compiler we are using for Excelsior JET development is again a Native XDS-x86 branch customized for our specific needs, so I do not think we'll ever release it to the public. In short, we are not going to finance a complete port of XDS to x64 or, for that matter, any other platform, ourselves.

    Excelsior JET 5.0 Released

    Excelsior JET 5.0 introduces Java Runtime Slim-Down, a new deployment model that may help you significantly reduce the download size of Java SE applications. With it, you may exclude certain components of the Java SE platform from the installation package, namely AWT/Java2D, CORBA, JDBC, JNDI, JSound, Management, RMI, Swing, and XML, provided they are not used by your Java application. This release also delivers a major performance increase over the previous versions. As measured with two standard benchmark suites (SciMark2 and SPEC JVM98), the composite scores have improved by a factor of 1.7 compared to Excelsior JET 4.x. Full information on new features and improvements Download the fully functional Excelsior JET 5.0 Evaluation Package Vote for Excelsior JET now! Voting for 2007 Java Developer's Journal Readers' Choice Awards ends on May 31st. Excelsior JET is nominated in the "Best Java Virtual Machine" category. This is your last chance to support our nomination. Please vote for us today!

    Please make JET compatible with upx

    Maybe this can be worked-arround some time in future, as it effectivly destroys the ability to decompress in-location. I guess this is also the reson why aspack works (but needs exectly the size of the compressed executable more RAM). Is it possible to instruct UPX or any other packer to compress executable sections selectively?

    Please make JET compatible with upx

    . . . By the way the "Global optimizer" has the same disadvantage. If applications would be linked only dynamically all jet-dlls could be shared every time an jet-compiled application is launched. However you also give the developer the choice here to reduce download size and enhance performance. This is not quite the same disadvantage. You can optimize several Java apps sharing most of their classpaths together into one EXE, adding a main() method that would dispatch control to one of those apps' main() methods accoring to the command-line arguments. Well personally I would like to be able to compress jet-executable because of real use-cases: * Deploy jet compiled demo's on an USB stick which should be able to run right out of the box. Every MB is quite expensive if you deploy hundreds of sticks. This is a very good point. I have no idea why USB sticks and flash memory cards escaped my attention when I was writing my previous post... OK, yet another point taken. Have you used the Executable Image Optimizer? It may substantially reduce the startup time, especially combined with the Global Optimizer. The disk footprint of the complete Sun JRE 5.0 is 70MB and you cannot remove much from it without violating the Sun license. We have no idea what all those packers expect to find inside the executable, and have no resources to investigate. Most likely, this segfault is not the only problem and finding all of them will likely take much more than 10-15 minutes. What we could possibly do and what I think would actually work much better than reverse engineering all those packers on our side is us providing packer authors with a document describing the parts of a JET-compiled executable that must not be compressed, under a non-disclosure agreement. But again, this will take much more than 10-15 minutes and we have other commitments right now. After we figure this one out, there will likely be more "interesting things to find out". We have gone through this more than once, with our own products and with third-party software. I have not heard back at all from authors of quite a few Java tools and applications whom I contacted in the hope that they might be interested in what we are doing here at Excelsior. You have to ask the packer authors whether they would be willing to help; without that, your statement is worth nothing. Sure. However, there are just a few users asking for this feature (maybe one user less, as LinuxHippy and JavaJulia post from the same IP address ). In particular, we have many paying customers asking for Java 6 support, that's a #1 request. I do not think we'll be able to work on anything else except Java 6 plus some features that we did not finish in time for Excelsior JET 5.0 release, schedule for next week.
