j2sdk-1.3.0-Sparc Problems!
Hello Everyone, are there any Processor-Requirements with this Version of j2sdk for Sparc-Linux? We made a short try on an old Ultra 2 and did not get any Standard-Demo to work. Mostly we got ArrayIndexOutBounds-Exceptions. Is this a Problem with the old Ultra2 or does our Distribution (Suse7.1 on Sparc with Kernel 2.2.x glibc2.2) not meet the requirements ?

Installing JRE 1.3.1 on CF-device (Compaq Ipaq)
Hi all I'm new to this list, and I don't know if this has been discussed earlier. I tried searching the archives, but didn't find it there. My question is about the possibilities of installing Blackdown 1.3.1 on a CF pcmcia storage device on a Compaq Ipaq. Can it be done? I'm running Familiar .4, 16 MEGS Flash, 64 RAM and plan to use a 128MB CF pcmcia card. A brief howto would be nice... :) Best regards Jøran -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

hi all, i have some code which is as below : public interface AccountSearch extends AccountSearchBusinessInterface, EJBObject the extends keyword is followed by two class names. is this valid java. this code is from a project i'm trying to understand which is written for the J2EE platform. Is there some other java compiler which accepts multiple classes after extends keyword. please help me if you can. thanks in advance, vijay >From: Jøran Barkhald Sandberg <[EMAIL PROTECTED]> >To: <[EMAIL PROTECTED]> >Subject: Installing JRE 1.3.1 on CF-device (Compaq Ipaq) >Date: Wed, 27 Jun 2001 14:19:25 +0200 (MEST) > > >Hi all > >I'm new to this list, and I don't know if this has been discussed earlier. >I tried searching the archives, but didn't find it there. > >My question is about the possibilities of installing Blackdown 1.3.1 on a >CF pcmcia storage device on a Compaq Ipaq.

The dynamic linker does not require this and trying to execute a shared library usually results in a core dump.

Problem with 1.3 and J2EE1.2.1
Hi,
A few days ago I installed on Debian 2.2 the j2sdk1.3 from the debian
file.
$ java -version
java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build
Blackdown-1.3.0-FCS)
Java HotSpot(TM) Client VM (build Blackdown-1.3.0-FCS, mixed mode)
I also JAVA_HOME set.
$ echo $JAVA_HOME
/usr/lib/j2sdk1.3
I was previously running 1.2.2 tarball from Sun and had no problems.
Here is the error (typed from dialog box) when I tried to deploy some
working apps.
There was a deployment error. java.rmi.ServerException: RemoteException
occured in server thread; nested exception is: java.rmi.RemoteException:
Error processing ejb jar: access denied (java.io.FilePermission
/usr/lib/j2re1.3/lib/ext read)
>From deploytool window
...
Remote message: Deploying Ejbs
Remote message: Processing beans
Remote message: Generating wrapper code for BankAccountEJB.
Remote message: Compiling wrapper code
No hints in server window.
I tried messing with the jre java.policy.
# cat java.policy
grant {
permission java.security.AllPermission;
};
No luck. The server.policy and client.policy for the J2EE both have
FilePermission for the ext dir.
Any help appreciated,
Eric

This was the problem, as someone on a different list also informed me. I had been given access to a machine remotely and didn't know what processor was being used. Is there some way to check this remotely perhaps? [quick check of system properties] I guess typing printenv HOSTTYPE might help. It all sounds so simple after the event ... Anyhow, thanks to Alan, Franz and Amol for various helpful comments on the java library issues which have helped advance my understanding of the issue.

Linux Java IDEs
It is with a heavy heart that I post this... IBM has just announced VisualAge Java 4.0 with availability in late July, and guess what? There is still no Linux version! Wow, I'm so surprised! All we *still* have is the incomplete and known-to-be-buggy 3.02 that uses JDK 1.1 with Swing 1.0 (gag me with a spoon...) But I'm not posting to whine about that; rather I want to ask you guys which IDE our company should use instead, since IBM is obviously not interested in license revenue from shops that use Linux. We are evaluating JBuilder and Forte/NetBeans. My impression of JBuilder is that it's somehow... I don't know, *quirky*. It may seem strange for a programmer to rely on gut feeling when evaluating an IDE, but something about that product just makes my skin crawl. Forte looks promising, but when trying it, I encountered the most spectacular windowing bugs I have ever seen. For example, when switching to a different desktop and back again under KDE, the source editor started to drift... and the window actually slid right off the desktop, never to be seen or heard from again. It would actually have been quite comical if our company hadn't already invested thousands in VisualAge... but that's another story. So I downloaded NetBeans 3.2. I had seen NetBeans before Sun bought them out, back in the JDK 1.1 days, and it was just unusably slow. Now, with faster JVMs and faster machines, it's definitely worth a look. I haven't gotten very far with it yet, but what advice can you guys offer? What IDEs should shops with Linux coders consider? Let me give some background first: our two top Java programmers (oh, is that me?) are total penguinistas; apart from the pride issue, it would result in an unacceptable loss of productivity for either of us to switch operating systems (in fact, I just turned down a machine upgrade because it would be too disruptive). This despite the fact that over the past few years we have put out tens of thousands of lines of Java using only a text editor (jEdit RULEZ!). However, we are trying to train some BASIC and RPG programmers to use Java in the hope that we can all just get along and maybe even share some code, and they run W**. So the criteria are that the IDE has to be relatively easy to learn (yes I know, then why were we considering VisualAge in the first place) and yet full-featured enough to offer help to these poor lost RPG souls in their quest to write PC applications that access data on our AS/400s. Oh, yeah, and it has to be available on both W** and Linux. What should we do? P.S. Don't get me wrong, I have spent the last couple months intensively studying VisualAge (including taking IBM course OB75), and got to the point of infatuation, even obsession with VisualAge before realizing that IBM was going to "OS/2" the Linux version. In an ideal world, that is the choice we would have made, but we can't wait any longer. It was a major tussle to convince these new Java programmers that they should learn by hand-coding and only then pick up an IDE; we definitely can't wait any longer to put IDEs on their desktops. -- == Glenn Holmer ([EMAIL PROTECTED]) -- You can now flame me, I am full of love, and will ignore any insults, because that is how good my Gnus filter is. -- -Miguel deIcaza == -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Perhaps if you were a little more specific, we could remove the creepy critters. JBuilder is an all-java application, so it is very dependent upon having a stable JVM. You don't say which JBuilder you tried, but if it was JB4, the bundled IBM JVM was absolute crap. Replace it with Sun's 1.3.0 or 1.3.1 and the thing works great. Borland has since released a port of Delphi for Linux, Kylix. I'm confident they plan to support Linux into the forseeable future. I selected JBuilder for myself over a year ago because at the time it was the *only* IDE which had a Linux client *and* JKD 1.2.2 support. IBM was still in the 1.1 dark ages, and there was no other downloadable eval for Linux available. Borland seems to be on a 8-month release cycle, so new versions some out regularly. JBuilder 5 just hit the streets a few weeks ago. The free 'Personal' edition isn't available for download yet, but you can order an Eval version of Enterprise to try out. (JB5 has a Sun JVM bundled this time, no more broken IBM junk!) -- Joi EllisSoftware Engineer Aravox Technologies [EMAIL PROTECTED], [EMAIL PROTECTED] No matter what we think of Linux versus FreeBSD, etc., the one thing I really like about Linux is that it has Microsoft worried.

At the moment I use vim (for the syntax highlighting) and Ant. Works on both Windows and Unix. Some people prefer Emacs and from what I can tell it can be a pretty awesome development environment: http://www-106.ibm.com/developerworks/java/library/j-emacs/?open&l=302,t=grj,p=Emacs Other people use Make instead of Ant but I find Ant easier to use and it's extensible too. I don't know why I keep going back to vim but I guess I have never found those gui building features helpful and never had luck doing complete code cycle stuff with them. Besides I almost exclusively write server side code and not any Swing. Also, I use a Pentium II 266MHz laptop so it's a little underpowered for most modern IDEs. This probably doesn't really help you but I wanted to raise my hand and say that there are people how are very productive even without using one of those bloated IDEs.

I suppose it does have it's quirks, but I have yet to find and IDE that doesn't. Perhaps it's a matter of finding the one with quirks that are most agreeable to one's own. Borland also has news groups you can get just about any question answered via. I use JBuilder on both Linux and Lose2K.

Oops did I say that? This is one of those dirty little secrets that tends not get mentioned in the 'minimum system requitements'. And thank you for pointing it out. Goodness knows I've also written plenty of code with NEdit/JEdit/XEmacs. Side note, if you have the system for it, a good IDE has tools that speed just about any kind of coding, not just UI building. ~Rob -- wYRd.:|:[EMAIL PROTECTED]:|:.prohibitions void where offered de recta non tolerandum sunt -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
