| Hello,
|
|   Can Java Servlets be developed on a Linux box? We are setting up a

| web server and want to use Java Servlets if possible. Is there a Linux
| version of the Java Servlet Development Kit or do I need something like

If you run the apache web server you should plug in mod_jserv 0.9.11 
available at:
http://www.apache.org/java/

I manager to get servlets up and running with apache 1.3.0 and mod_jserv 0.9.11

Good luck,

I use the benchmarks which are included in the Kaffe distribution (at

Re: JDK1.1.6v4a can't find library libXp.so.6

[A . KLOS]

I have the same setup as Wim does (RedHat4.2) and encounter the same 
problems: can't load library libXp.so.6 .
Upgrading to a newer version of XFree86 should be easy with the RPM 
mechanism of RedHat. Unfortunately RedHat 4 is linked against libc5 and 
RedHat 5.x is linked against libc6 (a.k.a. glibc).
I am afraid that the only RPM of XFree86 3.3.2 I can find will be 
linked against glibc or is there anybody that knows of a  XFree86 3.3.2 
RPM linked against libc5?

There *IS* a plug-in port available for Linux. I've got one somewhere. 
Don't remember where I got it from and I didn't find the time to give 
it a try. I think it even has the name beta-version: Activator...

 I did try the windows version though, and that one worked once pretty good.
Nowadays, I can't use the plug-in anymore, since upgrading/uninstalling

for win32 and picked out the stuff related to CORBA (something like

and re-zipped it as OMGCORBA.zip). I used this class archive

Maybe it has something to do with class access modifiers. Is you main

Indeed, you need to generate the java source code with the windows
JDK. Some other things

You also will need to have a C/C++ compiler on Windows, since JavaIDL
use the preprocessor of any existing C/C++ compiler (however they recommend
MS VC++ 4.2 or higher I think :-(  )

I was not able to start the nameserver on Linux. I can't remember what 
the error message was, but it just didn't work.

| Certainly not from me -- I'm very tainted in a lot of different areas wrt
| Java.  I view that the Linux community has two choices:
|
|a) we wait until completely open source versions of the Java VM, including
|   all the bells and whistles (in the meanwhile not being able to
|   develop Java applications on Linux)
|
| - or -
|
|b) we have some members of the community make available state of the art
|   versions of Java, and, *in parallel* others in the Linux/open source
|   community work on catching up with open source versions of Java.
|
| The second alternative is what we have now.  I think it's the best of both

I completely agree with Steve's point of view. There are a lot of 
companies that are less open than Sun and they try to get as much 
feedback as they can from the IT Community. I think Sun is doing pretty well!

| Hello,
|
| We have been able to get the JDK1.2beta CORBA implementation to work on
| our Linux box.  All we did was unjar the jdk1.2beta classes.zip and then
| jar up all the org/omg stuff into a new archive.  Put the new archive in

| we've experienced no problems with it; it even runs fine using the

| however :(

I did exactly the same and worked perfectly for me as well, but I 
didn't try it with JIT compilation switched on.
Please note that you won't have an IDL compiler under Linux, because 
that part of JDK1.2 isn't written in Java :-(
The problem I experienced (with JDK1.2b2) is that I couldn't start the 
TransientNameServer under Linux, although this should be pure Java. It 
simply set something like:
"Not supported under Linux"
Maybe this was politics

| Hi,
|
| Has anyone seen this strange problem?  Happening under both solaris
| jdk1.1.6 and linux jdk1.1.3.
|
| For a class named package.Name javah is generating stubs named
| package_0005fName.c and package_0005fName.h
| What do these '0005f' strings mean?

I had the same problem when I decided to put my classes into a package  
with a name containing an underscore (com.origin_it.)

0005f is probably either the unicode or ascii code for the underscore.  
IU asked a question to the guys at JavaSoft if this is normal behaviour  
or not, but I did not get any reply yet.


Regards, Addy.


P.S.: please let me know if it indeed has something to do with an underscore.


|
| The strangest thing is this is happening for only three distinct classes

| Hi,

Im am using Swing 1.0.2...

Which version of JDK do you use? Because JDK1.1.6 for Win32 has got a 
JIT and use that one by default (unless you explicitly disable the JIT 
with java -nojit...)
JDK1.1.6v2 hasn't got a JIT built in, but you could use one called TYA 
(v0.7: http://www.dragon1.net/software/tya/) and takes only 50K.

It improves the speed quite a bit (aprox. 3 times faster), but not as 
dramatically as the JIT that comes with JDK1.1.6 for Win32 (symantec JIT).

Furthermore TYA is not entirely stable yet, but is definitely worth to try!

For Java3D you will need a shared llibrary that will interface between

Mesa...). You could download either the Solaris version or the Win32 
version of Java3D and rip the classes from there, but you still need 
the native library..
For Java2D I am not really sure, but I think more or less the same

You have to put your stuff in a JAR-file and sign that JAR-file using a

JDK1.1.x ships such a tool called javakey. javakey uses an alogorithm, 
called DSA, which is a public domain encryption algorithm.
Netscape however doesn't understand DSA, but only RSA instead, which is 
patented by RSA Inc.
Netscape delivers a free tool called SignTool (formerly known as 
Zigbert, I believe), which you can download somewhere from 
developer.netscape.com with which you should be able to sign your 
applets in a way the Netscape browser understand it.

The Internet Exploder is a totally different story, which I don't know 
to much about

Re: Java DB browsing utility

[A . KLOS]

I know of a guy who developed a utility called SQLExplorer.
Don't ask me where I got it from, but you try to search with this name 
as a keyword.

Cheers,

Addy.
