The thing is, that netscape will complain if there is anything else but java40.jar in your classpath (because of classes.zip that contains diffrent versions of the same classes). Try only havoing java40.jar in it, and add other classes and archives one by one. You should also use a script to start up netscape. This script will just set the Classpath, then start netscape. Since a script is ran in a subshell, it will not affect any other processes that use java Papi -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

A little help
Hi I'm trully a newbie to Java. I've been reading the Java tutorial available at java.sun.com but i need to make a quick presentation of a small applet and I need a little beet of help. If you point me in the direction of specifics docs i will appreciate equally, waht i need are just examples. My applet needs to present a jtree with rootVisible=false. THe children might not exist, but if they do they will be retrieved thorugh JDBC (This is not important). I would like to use the JTree constructor that accepts an array of objects so that it wouldn't show the root node. The question is : (i feal really stupid about asking this, but i really need it) How do I create the array of objects ? Let's say i have a tree structrure like this: Child1 Grandcilhd1 GrandGrandchild1 Grandchil2 Child2 Child3 Can you please help me? Thanks P.S.: How do I create a empty array of objects.

CLASSPATH problem unresolved
hello, I have a problem by making some programs runs on Java for Linux (I have the jdk1.1.7 and glibc, with SuSE Linux 6.0 (KDE)). I have seen in the mail archive that there are very often some informations about the way the CLASSPATH must function, it has been very usefull for me, but in spite of these explanations, I haven't been able to make run my programs. I get 'can't find class org.w3c.rdf.SiRPAC' or 'unable to initialize threads'. I want to run the SiRPAC class that is in the directory $JAVA_HOME/lib/org/w3c/rdf/. when I type the java execution commant, I'm in $JAVA_HOME/lib. I have tryed the following things and traced the execution of the .java_wrapper script: 1) java org.w3c.rdf.SiRPAC -> the classes.zip is found but the result is 'can't find class org.w3c...' that's ok, the path to this class is not given 2) java -classpath $CLASSPATH org.w3c.rdf.SiRPAC with a CLASSPATH containing .:$JAVA_HOME/lib/classes.zip:/$JAVA_HOME/lib/org -> the classes.zip is found but the result is 'can't find class org.w3c...' 3) i have tryed also to change the .java_wrapper and put the directory $JAVA_HOME/lib/org in the CLASSPATH of this script, but it still don't work. I really don't know what to do, I have tryed really a lot of things without success. What do you think it could be. thank you Claude Le Berre -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

Trouble? Contact [EMAIL PROTECTED] You simply need to get a copy of the libstdc++etc. on your system. The docs distributed with JDK1.2 describe that it was built using a Debian system, and that it may not work for you if your binary environment is very different from this. Go to the Debian site and download the latest version of their libstdc++ package. Then unpack it using undeb if you need to, and copy the libraries from the usr/lib subtree which is created to your usr/lib. That should take care of this error. -- Paul Gangwisch [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

Re: CLASSPATH problem unresolved
Claude, Try this: unset CLASSPATH java -classpath $JAVA_HOME/lib/classes.zip:$JAVA_HOME/lib org.w3c.rdf.SiRPAC I don't think that you need $JAVA_HOME/lib/org, just $JAVA_HOME/lib so that the JVM can then fine org.w3c... You shouldn't need the '.' in your classpath, unless there are additional classes that you are trying to execute, after SiRPAC is running. In general it's best to avoid setting CLASSPATH. I do it myself but I've read that you should never have the CLASSPATH environment variable set. Make sure that the org/w3c/... dirs and class files are readable by the user you are using to execute.

Well, the problem is that you have the CLASSPATH wrong here. If org is in the class name "org.w3c" then it should not be directly in the classpath. Since you have actually placed something into the JDK directories you may wish to put the class tree in the $JAVA_HOME/classes directory as this is automatically part of the CLASSPATH (unless you use -classpath option) >> 3) i have tryed also to change the .java_wrapper and put the directory >> $JAVA_HOME/lib/org in the CLASSPATH of this script, but it still don't >> work. Again, you are pointing to the wrong place. You would need $JAVA_HOME/lib since the "org" part is part of the class names themselves. Again, if you are putting things into the JDK directory tree, do so in the $JAVA_HOME/classes directory and the wrapper will automatically find it.

I'm currently updated my linux system with glibc based one and found big problem in my Swing based JAVA program. It simply stops responding when I open dialog and close it. Then the frame does not respond me and is related, I think, glibc problem.

So, the question is that wherer can I find glibc 2.1 based or compatible jdk 1.1.7v1a with native thread ? I hope I can get this because it simply faster than my previous green thread based 1.1.7v1a.

Re: (Slightly) off topic: Piping output from std err to file
Just like I said: java MyClass 2>error.log "2" stands for "stderr" in shell redirection, same as "1" is for "stdout" and "0" for "stdin" So if you want to put both System.out & System.err in the same log, you may use: java MyClass 2>1 1>error.log If u r interested in, I wrote a small class that replaces System.err and has some useful features: - writes everything from System.err to console, logfile, message dialog, or any combination of these three. - any time an uncaught exception occurs, it pops up a message dialog (JOptionPane) showing the stack trace. - notifies your application each time an uncaught exception occurs.

Re: A little help
Your import statement (in your teste code) must be wrong; otherwise, java
would pick it up.
To determine if its a CLASSPATH issue, try this:
javax.swing.tree.DefaultTreeModel model = new
javax.swing.tree.DefaultTreeModel(root);
That'll tell you if you left out the import, got the import wrong, or your
CLASSPATH is screwed up somehow. (Honestly, though, if the CLASSPATH were
screwed, you'd be getting a lot more errors than this one--I'm betting my
money on the import statement.)

What I can suggest is that you write a custom ClassLoader that uses java.net.URL to connect to a given web server, check dates (against the .jar in your local path), download the .jar if necessary, then proceed with normal class loading (which is probably your "SmartUpdate" idea in a nutshell). Are your jars compressed? JDK 1.1 had a problem with compressed .jars, as I recall, but I'm not 100% sure of that. Alternatively, I don't see any reason why you couldn't pull the source for URLClassLoader out of 1.2, put it into your own "java2" package, and use it within java 1.1. You'd have to make a few source modifications to adjust for the changed ClassLoader rules in 1.2, but that shouldn't be rocket science. >Any past experience in this area would be helpful... > I haven't done this precise thing, but I've done a lot of work with ClassLoaders; I'll be happy to help as best I can.

Re: Possible to add a horizontal scrollbar
> Hi
>
> Is it possible to create a horziontal scrollbar in a JComboBox? Any idea
> and
> help will be much appreciated!
You can add your own cell renderer by using the setRenderer()
method on JComboBox(). Here is an example renderer:
import java.awt.*;
import javax.swing.*;
public class BasicListCellRenderer extends JTextField implements ListCellRenderer
{
public BasicListCellRenderer()
{
super(25);
setOpaque(true);
}
public Component getListCellRendererComponent(
JList list,
Object value,
int index,
boolean isSelected,
boolean cellHasFocus)
{
if(value == null)
return this;
setText(value.toString());
return this;
}
}
So instead of extending a JTextField you might extend another
component that is a textfield contained in a ScrollPane which
is limited to horizontal scrolling only.

Re: JARs and performance...
Thanks for the reply. I have thought about pulling the class out of 1.2, but was not certain of the affects. Additionlly, I thought of just rewrting their code in 1.1.7. Either way that is an option. The Jar will consist of classes the will be run as an application/applet/serialized bean. But for the performance part the applet is the big concern. Such a big jar, start off with big problems.

JDK 1.1.7 green threads problem?
I'm trying to install and try out an XML app server called Enhydra ( http://www.www.enhydra.org ); it requires a JDK be installed. With jdk117_v1a installed, I get the following error wjen I try to start it: > B./run_demos /usr/local/jdk117_v1a/bin/../bin/i486/green_threads/java: error in loading shared libraries: /usr/local/jdk117_v1a/bin/../lib/i486/green_threads/libjava.so: undefined symbol: _dl_symbol_value system has RedHat 5.2 installed. If I try it against jdk1.2prev1, it fails becuase it can't find classes.zip. Is that file gone from 1.2? Unrelated - the Java-lInux FAQ suggests running a test with appletviewer to verify a working jdk. Did the stand-alone applets dissapear between JDK 1.1.6 and 1.1.7? Thanks.

I've been looking for a way to provide users of my software with a "SmartUpdate" feature. Your idea sounds great, the only problem is when your want to save the new JAR in place of the old one: under Unix it should work, but under windows the original JAR is locked and it is impossible to squash it with the new one. Would you have any idea on how to replace a JAR in-place and circumvent file locking under some platforms? This problem has been bugging me for more than a year.

You can use JNI Invocation to create the java VM, inside the Java app drop the .jar into a new directory (call it "incoming" or something), then copy the .jar over to the Java directory when the java VM exits. Beyond that, I'm not sure--it really depends on how the Win32 JNI code is opening the file for use--if they're using exclusive locking, then I think you're SOL unless somebody knows of a Win32 API call that can work around or break an exclusive lock. Give me a bit (can't at the moment--busy), and I'll see if I can't figure out how they're doing it under the hood.

Re: java versus c++ or perl
Oh, Lord, what, you WANT a flame war? Look, here's my bottom line: With Power Comes Complexity. Perl is simpler than Java, Java is simpler than C++. With that simplicity you lose a corresponding amount of power. But the end result is that it doesn't matter--you can accomplish just about any project in just about any language. C++ will be fastest, Java will come in second (due to the presence of JITs and the like), and Perl will be last. The "best" language to use is the one that (a) everybody feels comfortable with, (b) has the capacity to easily do what the project demands, both now and in the future, (c) produces maintainable code that, when everybody on the project leaves and Management wants an update later, can easily be understood by the poor schmuck who inherits it all. My personal preference is for C++ and Java, since (a) those are the two languages I know the best, and (b) I'm adept enough with either one that I can produce reusable code that can be used in a variety of situations. If I had to choose one vs. the other, I'd lean towards Java, simply because it's a nice compromise between a high-level language like Perl and an object-oriented language like C++--not too much power sacrificed to get some nice simplicity. Java also has the advantage that Perl (AFAIK--I'm not even a Perl newbie) lacks in that Java has JNI, which would allow you to "call down" to C++ code if necessary. C++ code can also create a Java VM within it (again via JNI), so using one doesn't exclude the other, and I think Perl can also be fired up within a C++ process via library calls--why not use all three?

Re: After RedHat 6.0 Install, JDK Error !!!
Hello, I just fixed the exact same problem. Go get jdk-1.1.6 from blackdown. It will work (take the latest version). If you are a user of jfc, it will get broken. Because, for some reason, .jar files written in a later version are broken. To fix this, find a box that is able to decompress it (jar works almost exactly as tar, so to extract, just type jar xfv file_name.jar). Then zip it.

Re: (Slightly) off topic: Piping output from std err to file
Hey, this is an easy one. You could have found the answer with man bash (but who the heck wants to read the whole thing!!!). I will first give you the little recipe, then explains what it does (in case you don't care). some_command 2> some_path_to_a_file Bash (and like most shells) uses 2 streams. stdout and stderr. stdout is 1 and stderr is 2. You can create more streams if you like, but, I am not sure how, since I do not use (and do not understand what I would do with) more than these streams anyway. You can also redirect a stream to the other one like this some_comand 2>&1 >/dev/null This will make any command truely shut up. It is important to note that if you use pipes, only stdout is redirected, and if you redirect stderr at the end of the pipe, if the first command gives an error, it will be printed on the screen.

Hey, I think splitting this file into more than one is a VERY good idea to start with. There is a programm called fastjar that is available from freshmeat.net.

Trouble? Contact [EMAIL PROTECTED] > Well, this has a lot to do with want you want to accomplish. Once you get to know perl, it is faster to develop many things (such as databases) than any other languages. The advantage java has over other alternatives is the fact that it takes cpu cycles from the users, not your machine. The user also doesn't have to wait for the new page to be downloaded. Everything will be displayed in real time. If you think a user will have to do many requests before he leaves your site, use java. It is longer to load, but, it does the job on the spot after that. On the other hand, it is realy long to load compared to html. So, if you think the user will do simple requests then leave, a good old cgi is the way to go. The problem, is that if you think too many users could log in at the same time, the cpu cycles used are yours, not theirs, to then again, java/javascript still has some advantages. In my experience, java is at it's best off web pages. I've seen very few sites that use java that SOULD use it. If there is an alternative that does the jobs usually, the other alternative is best (from the user's point of view).
