Java Forum / General / December 2007what platform do you code on?
I am attempting to figure out what platforms I need to test a program I am developing on and thus am interested in finding out what platforms people are using on x86 hardware. Please answer the following and send it to me privately at aryeh.friedman@gmail.com: 1. Do you use Linux to develop Java? If so what distro and JDK version? 2. Do you use FreeBSD to develop Java? If so what version (i386 or amd64?) and what JDK version? Do you use JavaVMWrapper from ports? 3. Do you use Windows (XP or Vista) to develop Java? If so what version and what version of the JDK? 4. Do you use Eclipse? If so what version and on what OS's? 5. Do you use NetBeans? If so what version on what OS's? 6. Do you use command line based Java development? If so on what OS's and what command shell do you use? > I am attempting to figure out what platforms I need to test a program > I am developing on and thus am interested in finding out what [quoted text clipped - 3 lines] > 1.

All of my work and home java projects build from the commandline, though I usually use the IDE for the code/test cycle. Ant works nicely on windows and linux. I do have some bash and perl scripts for deployment of webapps to tomcat, or for installation of daemons on the server at home. At work, the deploy process is more complex than is worth documenting here. -- Mark Rafn dagon@dagon.net <http://www.dagon.net/> > I am attempting to figure out what platforms I need to test a program > I am developing on and thus am interested in finding out what > platforms people are using on x86 hardware.

The program I am asking about specifically is an extension to my company's unit testing framework and basically was attempting to figure what configs I needed to test it against... the main things is adding plugin support for eclipse and maybe nb and making it localization ready (it will only come with american english but people are free to make their own resource bundles) 2. At some point in the future we plan to offer our own change management (better term then version control because it incompasses more) system and thus we ask about stuff then. But I would like to know: 1. If there was a commerical unit testing that was reasonable priced (less then $50... currently priced at $10) that had the following features (plus the ones listed above) would intrested: * Ability to set the type of test at run time and test method by test method (i.e. unit, integration, system, "all", etc.) * Flexible in report format and frontend UI * Complete source (user modifiable [see my blog noted below for more info] at essencially the same level as any open-source product) * Localization * Maintains most of jUnit's semantics * Specifically designed to be a component of a larger development system Whould you be willing to buy it instead of staying with something like jUnit? 2. What other features can you think of that would work well?

Not really... just identify any obvious front runners... linux mostly because I am developing on FreeBSD so that is covered and I already have vista installed and for the purposes of this product that is close enough to for testing purposes to XP (I can run it in XP compat mode)... beyond that I was just figuring out what jvm to compile for and it looks like 1.5 is pretty safe (I use 1.6 for development) and what IDE's to write plugins for (with eclipse and nb being the only canidates) On Dec 7, 1:09 pm, "Aryeh M.

I know that is the case for the 3 major clients I've worked with over the last 3 years. Fedora 8 at home and work. RHEL, Solaris, XP at work. 1.4 and 1.5. Major app is BEA WebLogic 8.1 on 1.4 but nobody here uses WebLogic Workshop. A few use netbeans or others but most use Eclipse. Whatever version we want. Usually the latest. I know my prior client used WSAD but maybe they have moved on to Eclipse now. WSAD had an integrated queue tester and integrated wsdl2java tools and ws test tools. I've seen and do little to no cmd line Java dev. Tim > I attended a Borland talk at a JUG this summer where it was stated 80% > of Java projects still run on 1.4.

Some of the applications are starting to migrate to Java 5 (and in the nick of time, too).

No. But if I mark it for uninstall in the package manager, it complains about missing dependencies for ooffice. The first ‘it’ is java-1_4_2-gcj-compat. Reading the below, I think it is because I am on a 64-bit architecture and somehow, Yast thinks Sun’s java6 does not provide a 64-bit version, though it does. There are some problems there, e.g. it is also troublesome to deinstall java-1_5_0-sun and set java-1_6_0-sun instead, I had to run update-alternatives --config=java to fix broken links afterwards. And of course, no Firefox plugin, but that is Sun’s issue. I pasted some of the Yast conflict messages below, it goes on for about every OOO component, and for gnome-office and kde-office. I’m afraid it is in Dutch, but if you’re really interested, GIYF.

Out of courosity are there any decent java to native compilors that are: a) portable as to what platforms the compilor will run on b) Fully support 1.5+ c) Output x86 (any other processor is a plus) code d) Allow for multi lang mixing in the same executable >> I use Fedora 7.

It would require a lot of effort to create and there would probably be little interest.

I seem to remember they briefly had something called JavaOS which was actually a Linux distribution. There may have been several unrelated efforts of the same name, just to confuse the issue even more. Nevertheless JNode is one you can go and play with now. Mark Thornton On Dec 8, 5:25 pm, "Aryeh M.

I'm certain using the alternatives is a good solution to avoiding the gcj problems, but how well will it survive a clean install in FC8? I ask because I only use alternatives to replace Sendmail with Postfix and don't understand its internals. I use another approach. I don't claim my solution is the best, but it only requires minimal work (copying one file, replacing one symlink) to reinstate the JDK after a fresh Linux install, e.g the upcoming move from FC7 to FC8: - the precondition is that /home must be in a separate partition from those that contain the the system. This means that I can reformat the partitions that will contain Linux (/, /boot, /var, /usr) without losing files I've created or installed under /home. - I installed the Sun Java JDK and associated stuff (ant, JavaMail, etc.) in /home/java. /usr/java is a symlink that points to /home/java. - I put a file, java.sh, in /etc/profile.d which sets up the classpath, etc. to refer to the Sun JDK. On every login this will be found and run by the /etc/profile script. I keep a copy of java.sh in a directory under /home - That left the annoyance that, unlike FC6, in FC7 the gcj commands (java, javac, etc) have been put in /usr/bin, so I made sure that java.sh puts the java JDK before /usr/bin in the default PATH. - After a fresh install I copy java.sh into /etc/profile.d and recreate the /usr/java symlink. Job done: Java is back how I want it. Signaturemartin@ | Martin Gregorie gregorie. | Essex, UK org | >>> Lew schreef: >>>>> Also an old gcj1.4 somewhere, because OpenOffice needs it. [quoted text clipped - 45 lines] > - After a fresh install I copy java.sh into /etc/profile.d and recreate > the /usr/java symlink. Job done: Java is back how I want it. alternatives works by creating symlinks to what you want. You can override all the little /usr/bin/ links with --slave options to the alternatives command. So in my case, /usr/java/java is always a symlink to the current JDK installation ($JAVA_HOME), or at least the one in which I'm currently interested. # alternatives --install /usr/java/java jdk /opt/java/jdk1.6.0_03-32 1603 \ --slave /usr/java/jre jre /opt/java/jdk1.6.0_03-32/jre Right now, "1603" is the highest number for any "jdk" alternative, so it's the default when in "automatic" mode. I replace all the /usr/bin symlinks thus: # ln -s /usr/java/java/bin/java /usr/bin/java # ln -s /usr/java/java/bin/javac /usr/bin/javac # ln -s /usr/java/java/bin/javadoc /usr/bin/javadoc # ln -s /usr/java/java/bin/jar /usr/bin/jar # ln -s /usr/java/java/bin/javaws /usr/bin/javaws # ln -s /usr/java/java/bin/jarsigner /usr/bin/jarsigner # ln -s /usr/java/java/bin/javah /usr/bin/javah # ln -s /usr/java/java/bin/appletviewer /usr/bin/appletviewer # ln -s /usr/java/java/bin/rmic /usr/bin/rmic When I want to use a different JDK, I use alternatives --set jdk /opt/java/ibm-java2-i386-60 This puts alternatives into "manual" mode and forces the JDK to the desired one. All the other symlinks follow perforce. # alternatives --display jdk jdk - status is auto. link currently points to /opt/java/jdk1.6.0_03-32 /opt/java/jdk1.5.0_13 - priority 1513 slave jre: /opt/java/jdk1.5.0_13/jre /opt/java/jdk1.6.0_03 - priority 1600 slave jre: /opt/java/jdk1.6.0_03/jre /opt/java/jdk1.6.0_03-32 - priority 1603 slave jre: /opt/java/jdk1.6.0_03-32/jre /opt/java/ibm-java2-i386-60 - priority 600 slave jre: /opt/java/ibm-java2-i386-60/jre Current `best' version is /opt/java/jdk1.6.0_03-32.

Whenever a quick fix is needed, or if I need advanced editing (rectangles, macros, query replace using regexp, re-encode source files) I sometimes use emacs. I use a lot of command line utilities in everyday programming. Any decent bash with unix utilities does the job. To maniputate text, i use things like perl, awk, join, sed, grep, etc. To test communications, telnet. Sometimes I also use maven or ant directly without opening any IDE. I produce patches using diff from the command line when i need more control. I just posted because i didn't see anybody like me posting so far. :) Regards Marcelo Morales > 1.

Hmm. According to: http://java.sun.com/javase/6/webnotes/version-6.html then: #while 1.6.0 is the developer version. and: #Version 1.6.0 Used by Developers # #Java SE keeps the version number 1.6.0 (or 1.6) in some places that are #visible only to developers, which I read as that 1.6 is fine for developers (while managers and sales people should use 6). Or in other words 1.6 should be OK in c.l.j.p ! Arne >>> jdk 16 >> [quoted text clipped - 21 lines] > > Or in other words 1.6 should be OK in c.l.j.p ! Yes, it should, but he didn't say "1.6".

Certainly it does for someone like me who hasn't used FreeBSD. Stay with the regular version numbering and it will be clearer.

Richard Stallman elaborates a little more on http://www.gnu.org/gnu/why-gnu-linux.html //Roger Lindsjö >>> here is what I plan to do for linux: >> [quoted text clipped - 3 lines] > most users (even programmers). Richard Stallman elaborates a little more > on http://www.gnu.org/gnu/why-gnu-linux.html That's an extremely good point. However, people have gotten so colloquial with saying just "Linux" that it's come to be understood as a synonym for "GNU/Linux". Stallman is famous for insisting on all sorts of things that people ignore. Similarly, although Sun has tried to insist that as a trademark, "Java" only be used as an adjective ("the Java language"), people insist on using it as a noun. (Which, since as such it's a proper noun, must be capitalized, even if the trademark didn't require it.)
