Re: Experiences with JBuilder?
From: Carl E Tallis@ERS_TYSONS on 05/21/98 07:47 AM (Sorry in advance for the format - I'm on Notes, now.) I've used V. Cafe, and found it somewhat lacking. Version 2.5 (the latest) doesn't work well with Swing, and the visual/textual editing correlation is primitive (to say the least) compared to, say, what I became used to with Inprise's (nee Borland's) Delphi. I have JBuilder 2 on order now, and hope/expect that to become my standard IDE on Windows. As for databases (I'm guessing your V. Cafe didn't come with SQLAnywhere and DBAnywhere), I found a free, mostly JDBC compliant database called InstantDB (www.instantdb.co.uk). You could try that. [EMAIL PROTECTED] on 05/21/98 02:02:25 AM To: Carl E Tallis/ERS cc: Subject: Experiences with JBuilder? I want to develop a database application using Java. I want a tool that has database aware widgets. I can't find anything like this on Linux so I may need to use a Windows development tool and then run the Java code on Linux. There seems to be two commonly used Java/Database application development tools and they are Visual Cafe and JBuilder. Here are my questions: 1. Has anyone tried to use the code they generate on Linux? 2. Will they hook up to a JDBC database on Linux like SOLID Server or PostgreSQL? 3. Is Java on Linux (or Windows 95 for that matter) at the point where I can expect to develop end-user commercial software and have the stability and ease of use I need? 4. Are there other options besides Visual Cafe and JBuilder? I'm leaning towards JBuilder since the company that used to be known as Borland seems to be more open and states on their web page that they embrace all operating systems and are not Windows centric. The new version (2.0) just came out and I'm waiting for any sort of press reviews before purchasing. I have a demo copy of Visual Cafe but haven't got far into it since it doesn't like the SOLID Server I just downloaded (Windows95 version). SOLID says its a Winsock 2.0 problem and I've got to downgrade to Winsock 1.? for it to work. Any other databases supporting JDBC that I can download for evaluation so that I can test Visual Cafe?

The enterprise version is quite expensive. I didn't noticed your site wasn't an educational one, as IBM gives VAfJ for free for academic purposes (Even the enterprise version). You may post your questions at the ibm.software.vajava.ide discussion group at the news.software.ibm.com newsgroup.

We currently develop a commercial package entirely in java under linux, deploying on NT and Win95 for the most part (with one deployment to an Alpha running Digital Unix). Works great; stability is good, "ease of use" is of course entirely subjective but I find Linux easier to develop under than Win32. I don't use an IDE, so consider that in your evaluation. We've been doing the java thing for almost two years now, and 1.0 shipped more than a year ago (I'm coding 2.1 as I write). Only 8 customers so far, but at $50-$80K apiece not a bad living. :-) So yeah, there are issues, but it works for us and I'm loving it.

ported jdk installation instructions?
So maybe I'm being completely clueless here, but aren't there some instructions somewhere on how to do the installation of Steve Byrne's port? My first problem is that not being a Linux expert I have no idea whether I should use the glibc or the libc5 version and I can't find any helpful files that explain how I'm supposed to know which to use. Can I choose whichever I want, and if so why would I choose one vs. the other, or do I have to get the one to match my system (Redhat4.2), and if so how to I tell which one matches? So I grabbed both and looked around (1.1.5v7). There is the README file from Sun which has no Linux specific information but does have installation instructions for the platforms Sun supports. There is README.linux, which talks about various things but doesn't have specific installation instructions, and there's README.linux.src which has instructions for re-porting from Sun's full source distribution, but no instructions for installing Steve's prepared port. If we are just supposed to follow the instructions for Solaris from Sun's README, it'd be good if it said that somewhere. Maybe I just missed it. Perhaps it is as easy as untar'ing and moving the resulting jdk1.1.5/ directory tree to the appropriate place in the file system? But again, I didn't see that written anywhere. Am I just supposed to know that? -Karl Karl Pfleger [EMAIL PROTECTED] http://www.stanford.edu/~kpfleger/

Re: Experiences with JBuilder?
> There seems to be two commonly used Java/Database application > development > tools and they are Visual Cafe and JBuilder. Here are my questions: I can't help you directly, but we went with Borland's C++ Builder Client/Server a year ago. It cost $2k for 1.0. Now they've come out with 3.0 (I don't know what happened to 2.0) and they want $1700 for the upgrade. All we want is for some of the bugs to go away, but we're going to live with them because I'll be damned if I'm going to pay for the product twice in hopes that some dumb bugs are squashed. I don't know about Symantec, but perhaps their pricing is more reasonable. I'm sure the free-software world is behind a bit, but are they really that far behind?

Karl, Yes, http://www.blackdown.org/java-linux/docs/libraries.html is a start. Can I choose whichever I want, and if so why would I choose one vs. the other, or do I have to get the one to match my system (Redhat4.2), and if so how to I tell which one matches? The latest version includes its own loader, but as far as I know, you still should try to match what you download to your system's native libc. RedHat 4.2 is "old libc" rather than glibc (new libc). Perhaps it is as easy as untar'ing and moving the resulting jdk1.1.5/ directory tree to the appropriate place in the file system? But again, I didn't see that written anywhere. Yes, that's right. The wrapper scripts that are provided with the JDK discover what a good value for JAVA_HOME and CLASSPATH should be, and then set that for you (if you haven't set them already). They try to modify those environment variables if they're already set, but you should be OK at first to run without setting them yourself. Stephen

There isn't much functionality, but the Scribble application from the Java Nutshell handbook works. So far, Panel, Graphics, Font, and the mouse events are the only things working. If you run it under kaffe, you get a memory footprint of 6 megs vs 22 with the jdk. Anybody want to pitch in? =) . . . Sean.
