Re: Java Linux and Signal Handlers
Juergen, Many thanks for the info. It is not my desire to mix java and native code in the way you describe, but the following: I am working in a C environment, and I need to be able to call subroutines in a number of (pluggable) languages, of which one is Java. Some of those languages run-times (such as Java) like to install signal handlers, and thus I have the additional problem of ensuring that there are no conflicts. If there were some way for me to disable Java signal handlers and simply install my own, and then invokes Java's handling routines from my signal handler, that would be one solution.

Native Java applications
I would like to program with the JFC. But on the opposite I prefer native Java applications because performance reasons. What kind of possibilities do I have today? Thanks and Kind Regards.

Problem downloading JDK1.2
Hi there This isn't a bug, but I'm hoping you might be able to help me. I've tried twice to download the JDK1.2, from two different mirror sites (both the UK ones). But I can't uncompress the file. I've downloaded the latest version of BZip2, but when I try to uncompress, I get a message saying the archive is corrupted. bzip2 -tvv gives the following; jdk1_2pre-v1.tar.bz2: [1: huff+mtf jdk1_2pre-v1.tar.bz2: data integrity (CRC) error in data I'm downloading the jdk to my Win95 PC at work (hey, it's not _my_ fault they chose a sucky OS!), and transferring it onto a CD to take it home to my Linux box. Both downloads have the same byte count (24,551,380). I've also tried using bzip2 for win95, and I get the same message from bzip on the Win95 PC, and on my Linux box. I would really appreciate any help you might be able to give.

Sorry I mean native code Java application. Wait I'm confused. Isn't JFC just Swing? Why isn't that "native Java"?

RE: native code Java application.
The only solution that I found the is plausable today is to use ibms native code compiler. You have to purchase visualage for java enterprise edition. I was using it under the beta versions of it with swing 1.1. It works very well and it speeds up swing significantly.

Use the Apache Jserv - a module you can compile for use as a servlet engine with Apache. Check out java.apache.org Other than that you just need the JSDK classes which you can download from Sun.

kernel 2.0.37 with Alan Cox's ac9 patch?
Hello team, I already worked with your port of jdk 1.1, and it was really excellent. Now I'd like to work on the jdk 1.2. But I had no chance to find kernel patch 2.0.37 and Alan Cox's ac9 patch. Do you have any idea where to find them ?

glibc 2.1
I have been a happy user of jdk 1.1.7 until I tried out redhat 5.9 (trying out 5.9 because of new hardware I just bought). My question: is a glib 2.1 version of 1.1.7 going to be compiled ? I know most people are yelling for jdk 1.2 but I would think recompiling 1.1.7 wouldn't be too much of a hassle ? Any help would be greatly appreciated as I really love using jdk on linux instead of windoze95.

Drag & Drop
Dear all, I have been fiddling unsuccessfully with the Drag and Drop (dnd) features in Java. So far I have been able to do nothing since the only demo application I have (http://java.miningco.com/library/weekly/aa011299.htm if you are interested) does not run. I get an InvalidDnDOperationException exception with the message : " The operation requested cannot be performed by the DnD system since it is not in the appropriate state " I was wondering if anybody has managed to get dnd running and if so if she or he could enlighten me and the rest of the Java Linux community the the way to do it? If not : has anybody managed to get the click and selected mechanism with X to cooperate with Java LINUX ?

Parameter value weirdness
I'm seeing some weird behaviour with parameters that are passed to servlets
as blank strings, ie in a URL such as
http://machine/zone/servlet?param1=¶m2=. These parameters end up having
the value "null" (ie a 4-character string) rather than either a blank
string or a null pointer, which is what I would expect.
Here's the code -
Enumeration parmNames = inRequest.getParameterNames();
while ( parmNames.hasMoreElements() )
{
String key = (String) parmNames.nextElement();
String value = inRequest.getParameter( key );
// value == "null" here
// in case where parameter is passed as ?name=&name=value
}
Any ideas anyone? Thanks in advance.
