- list jar contentsI am trying to list the contents of a jar file.
I should be able to run
jar -t -f myjar.jar
but when I run this the command does not return and does not display
any thing.
I have to ctrl-c to terminate the app.
I can get the contents if I use the command line version of winzip.
I have tried
jar -t myjar.jar
and
jar -t -f myjar.jar
thanks for the help

See http://www.well.com/user/xanthian/java/TravellerDoc.html ;
sadly that links to a jar file containing a version about
1/3rd the size of the one I'm running now, which contains a lot
more featuritus captured as Java, but is nowhere near ready to
publish. If you want a "warts and all" copy of the current work
in progress, I can send one to you by email.

Funny you should say that. When I was
courting my current wife, she showed the
secretaries working for her a picture of
me, with an earlier incarnation of the
same beard (this was 1991) , and to a
one they responded: "You're marrying ZZ
Top!?!" I was a lot cuter then.

Posting unworkable URLs doesn't much
help. In anycities rabid insistance
that you get a chance to read one of
their misleading and deceptive "improve
your website" ads, before seeing
anything useful, they disable direct
access to anything that isn't an HTML
file they can corrupt.
To see the above picture thus takes
two steps:
Click here:
http://www.anycities.com/user/xanthian/KentImages/KentImages.html
Then choose the top link "this" to see
the above picture. If you look at some
of the others, you'll notice I've added
a bit of fur.
> TELL ME WITH A STRAIGHT FACE YOU CAN
> TELL THE DIFFERENCE!!!!!!!!
How to tell it's Dusty and not Kent the
man from xanth:
1) Dusty still has a lot of orange color
in the sides of his beard; mine is snow
white except for a score of black hairs
in my moustache.
2) No time in my entire life have I had
a babe like that on my arm, counting two
wives and a daughter all in wedding gowns.

- color palletI'm coding up a routine to dispaly a stacked bar graph using
Graphics2D. Each bar is made by a bunch of rectangles representing
each contributor. The color of each contributor should be different.
I need a way to assign these colors. The number of contributors can
change at runtime. Sequential colors should be well differentiated.
Does anyone have any suggestions for accomplishing this? I'd rather
not make the user specify colors at runtime.
Thanks,
Rob

- JSP vs XSLT?Which is better JSP or XSLT? I prefer JSP for two reasons performance
and less complicated to learn.
JSPs are compiled one time, then cached, unless the code changes. This
not the case with XSLT, as I understand it.
XSLT is very complicated to learn, in my opinion.
See this article by IBM on JSP vs XSLT:

- Sending XML as a String through a web service (Tomcat/AXIS)?Hi, I have a web service written with Tomcat/AXIS. One of my
methods receives a String. Is it possible to send a String of
XML through this method? Will the XML tags confuse the
underlying web service system? Or will the XML be "escaped"
(with the <, > characters rewritten somehow)?
Thanks.

- Runtime.exec and socketsI submitted this as a bug, but no response. Can anyone help?
FULL PRODUCT VERSION :
java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-b21)
Java HotSpot(TM) Client VM (build 1.4.1-b21, mixed mode)
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows 2000 [Version 5.00.2195]
A DESCRIPTION OF THE PROBLEM :
Runtime.exec() to start a new java program. The new java program
should create a socket connection to another program.
The socket will connect if created and used from the static main
method. It will also work if placed in a static method called from
main. It will not work if I create an object and have the object
execute the same code (which is what I need); it fails both times if
the method is static or not static.
If I run the java program from the command line and not by using
Runtime.exec, it works beautifully.
If while it is blocking I kill the first vm, then the second vm
continues.
ACTUAL -
Blocking
REPRODUCIBILITY :
This bug can be reproduced always.
---------- BEGIN SOURCE ----------
public class ProgA {
public static void main(String[] args) throws Exception {
Runtime rt = Runtime.getRuntime();
Process p = rt.exec("java ProgB");
p.waitFor();
System.out.println("Process Returned");
}
}
///////////////////////////////////////////////////////////////////////
import java.net.*;
import java.io.*;
public class ProgB {
public void service() throws Exception {
//If I move this body of code to main or another static method,
//the program works.
Socket s = new Socket("127.0.0.1", 5000); //Blocking
OutputStream o = s.getOutputStream();
o.write("test data".getBytes() );
s.close();
}

ProgB b = new ProgB();

- Interrupt on Java thread..I have two threads, one reading from stdin and writing to a socket
(requestThread),
one reading from a socket and writing to stdout (responseThread).
When the response thread gets a msg from server that an error occurs, it
closes the socket and calls interrupt() for it's thread group before
exiting.
But requestThread never seems to get the interrupt.
It is blocked(?) on a readLine() from the BufferedReader omn stdin.
What am I doing wrong?

- i18n in Swing, trouble.Hi,
I am building my first Gui with Swing, and in the same time I need to
use the i18n to make it work in Japanese and English.
I use Eclipse and its great Visual Editor to save time, all my files are
utf8 encoded. And, I am under WinXp...
My trouble is the following :
-> If I make a jMenu with some japanese hardcoded text, it appears fine
in my application.
-> If I use a ResourceBundle to get the text, I have garbage. I use the
following line: myMenu.setText(myBundleResource.getString("myTest"));
The .properties files for the japanese is also in Utf8
Do you have any idea why the text in the .properties file is not passed
correctly ? Any help would be really appreciated.
Best Regards,
Schlum

- Logging APIHello,
I have been using the logging API to log HTTP requests. I have an
object, which resembles a HTTP request and has methods to extract the
typical fields of a HTTP request.
Now, I have noticed that you can only pass log messages as a String and
not as an object. Also I saw that Formatters format "around" this
String. I think that is quite a limitation for my purpose.
What's if I have different Log Formats, which I would like to apply.
For example, there are different levels of verbosity. The apache log
format "combined" sends more output then "common". Maybe I also want to
define my own custom ones.
Then I would like to have a Formatter for each output Format. Do do
that, however, Formatters would have to be able to work on those HTTP
objects, which contain the fields.
That does not seem to be possible under the current logging API or am I
missing someting here? I really don't understand, why the message is
not being stored as an Object but a String - that only limits the use
of the Formatter.
Can somebody elaborate on this. Maybe it should be brought up with Sun?

java-programmer, JDialog (or any window) sizing
I would like my JDialog to pop up with a size that is just adequate to
contain what is within, which includes various components and layouts in
the hierarchy. I'm hoping someone can tell me in a nutshell what
sequence of operations to perform.

java-programmer >> JDialog (or any window) sizing
Thank you so much for the instant response. It works fine for two of
three cases. The third case still leaves me with a question. The
containment hierarchy in question has a JTable in a JScrollPane. I'd
like to set that portion of the composition to a particular size and
allow the containing JDialog and other elements to be sized around it
automatically. If I simply call pack(), the JTable area is much too large.
Your recommendation, please?

Preferred size of JScrollPane with JTable inside is:
Component c = new JScrollPane(new JTable());
System.out.println(c.getClass().getName()+ ": " +c.getPreferredSize());
javax.swing.JScrollPane: java.awt.Dimension[width=453,height=403]
You may change JScrollPane preferred size before calling pack()

Much to my embarrassment, I tried setPreferredSize(int,int) on the
JScrollPane and assumed that the method did not exist for the class when
the compile failed. I didn't think of using a Dimension object until I
read your post. I have it working reasonably well now.
Thanks again for helping. I know this is basic stuff, but it gets
pretty frustrating sometimes.

The JavaDocs (or an automplete IDE) are much handy here..
<http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/JScrollPane.html>
Do a search on 'setpref', and click the link.
'Voila' - setPreferredSize inherets from JComponent and
accepts a Dimension.

setPreferredSize came in with JDK 1.5. Prior to that you must
override getPreferredSize (and brothers).

I haven't been thinking in those terms, but I'm catching on as I scrape
the rust off my Java lobe. Thanks for the clue...

- What happensHi,
Am a newbie to CORBA. What happens when a CORBA object is destroyed? I
heard that its ORB reference becomes invalid? If this' true, what
exactly is meant by 'invalid'? What if I try to refer the object after
it is destroyed? And also how do I come to know if the object is
destroyed?
Thanks.

- class data sharing subjective test resultsHi all,
I made some tests with the new "Class Data Sharing" function
provided by the JVM (since version 1.5.0 / 5.0) and decided
to share my class data sharing discoveries with the group
(this topic is not often discussed here).
The tests were made on an Un*x system (Linux Fedora Core 3).
First of all, the performance gain is very real, especially
when launching lots of small apps.
Basically, it comes down to using the parameter/value
"-Xshare:off", "-Xshare:on" or "-Xshare:auto" (which is
the default) when calling the JVM.
The command line: "java -Xshare:dump" can be used to
force the creation of the memory-mapped archive file
(the shared classes). (btw this step is apparently
necessary on some Un*x systems!?. My system would
/not/ default to using the sharing, I had to
-Xshare:dump once and then add -Xshare:on to force my
application sharing the classes.)
I had some "text file utilities" I wrote in Java which I'm
used to call from the command line (or from shell scripts).
This is clearly one area where the JVM's startup time
is a problem. I noticed gain of about 30% in this case
(using a non-scientific approach repeated many case, with
and without CDS).
If the JVM is installed in userland, each user will have his
own "cached" file (classes.jsa, about 11 Mb on my machine).
If only one JVM is installed for all the users, all the
users will share the same classes.jsa file (JSA for "Java
Shared Archive").
It may be possible to force different identical JVM
installed in different userland to use the same classes.jsa
but I didn't try to do this (simply copying the classes.jsa
file from one user on top of the classes.jsa file of another
user doesn't work, although the files have the same
length [but different checksums]).
I was pleasingly surprised by those first results and I
decided to force all my apps to use the JVM 1.5.0 and its
class data sharing feature, including IntelliJ IDEA (which
comes with its own JRE and refuse to run with an 1.5 JRE
without some hacking).
After days of "switching" to an 1.5 JVM and forcing all my
apps to use class data sharing, I can tell that overall
everything "Java related" is a little bit more responsive.
It is particularly noticeable when calling Java utilities
from the command line (which is no surprise) but also when
running unit tests (I tend to launch my test(s) quite often).
The memory footprint is also reduced compared to 1.4.2
(when running several apps).
I'm curious about your results too :)
See you all very soon (and "hi" to the c.l.j.p. regular
I met on freenode's #java saturday ;),
Jean
P.S : If I understood correctly, Apple made their
own class data sharing "hack" for Java (way before 1.5)
and Sun basically copied their "idea". Whatever... This
means that developers using MacOS X benefits automagically
from "class sharing" since quite some time and have
nothing particular to do in order to use it.

- Problem with update Manager in eclipseHi
I have been trying to access the eclipse update site.
Unfortunately when I go on the newly created eclipse item
in the feature updates pane things seem to stop. A
message
Connecting... Connecting to
"http://update.eclipse.org/updates"
appears but nothing happens and the screen kind of hangs
until i press the red button (cancel current operation
option). I work from behind a proxy. I did the
appropriate settings in the preferences (entering the proxy name and
port). I expect to be asked for my username and password and
subsequently
be shown the builds. But nothing seems to be
happening.
But if I go to the eclipse item, right click and in
the properties select "website" instead of the "update
site" everything seems to work fine....as in i access the site
(updates still missing)
What is the reason of this behavior could i be doing
something wrong? I am new to eclipse....could anybody please help.
regards

- how to map from display metrics to physical metrics...Suppose I have a screen which is 1024x768, how can I map this rectangle in
pixels into physical world dimensions in meters or in inches? Actually I
want to know the physical size of the viewable area of the monitor...
Please help me...

requirements
It has to
0) be free to download and use

- Array reference in for loopI have a validate method in a bean class that works and now I want to
condense it into a for loop.
Here is what I have:
//firstname and lastname are declared earlier
public boolean validate()
{
boolean allOk=true;
if (firstName.equals("")) {
errors.put("firstName","Please enter your first name");
allOk=false;
}
if (lastName.equals("")) {
errors.put("lastName","Please enter your last name");
allOk=false;
}
return allOk;
}
My attempt doesnt work because I cant seem to figure out how to put
the array reference in the key part of the errors.put method:
public boolean validate()
{
boolean allOk=true;
String [] myarray = {firstname, lastname}
for(int i=0;i < myarray.length;i++)
{
if (myarray[i].equals("")) {
errors.put(myarray[i],"Please enter your " + myarray[i]);
allOk=false;
}
}
return allOk;
}
The results dont validate any of my data so I assume I have something
wrong with my array. Please advise.

- aliasHi,
I may be jumping guns here. I mean I'm totally new to java and yet, I
feel the need to do something like this for typing much less,
o = System.out.println; // problem, what data type for var of o here?
undefined.
or
alias o = System.out.println; // alias is supposed to be a special
command or the sort?
then, I do something like this
for (int i=0; i < 5; i++) {
switch(i)
case 0:
case 2:
case 4:
o(i + " is an even number"); // instead of System.out.println(i +
" is an even number");
break;
case 1:
case 3:
case 5:
o(i + " is an odd number"); // instead of System.out.println(i + "
is an odd number");
break;
default:
o(i + " is neither an odd nor even number");
// instead of System.out.println(i + " is neither an odd nor even
number");
}
Doable? How? TIA.

- Induction question, help needed.Help needed on this question. Any help is appreciated. Thanks in
advance.
Given a binary string (i.e. a finite sequence of 0's and 1's) we
choose any two digit substring 01 and replace it by a string of the
form 100...0 using an arbitrary (but finite) number of zeros. Prove
by induction that this transformation can not be performed infinitely
many times, i.e. this sequence of transformations must terminate for
any input string.

- "this" statement?The "this" statement that is used in the method "exitRoom" and "explore" is
that synonymous with an "Explorer" object?
public class Explorer implements PlayerBehavior {
private String my_name;
private String my_secret_word;
private RoomBehavior where_I_am_now;
public Explorer(String name, String word){
my_name = name;
my_secret_word = word;
where_I_am_now = null;
}
public String speak(){
return my_secret_word; }
public void exitRoom(){
if ( where_I_am_now != null )
{ where_I_am_now.exit(this);
where_I_am_now = null;
}
}
public boolean explore(RoomBehavior r){
if ( where_I_am_now != null )
{ exitRoom(); }
boolean went_inside = r.enter(this);
if ( went_inside )
{ where_I_am_now = r; }
return went_inside;
}
public RoomBehavior locationOf(){
return where_I_am_now; }

- Is there a startup banner class?Hello,
I have an application to which I would like to add a startup banner.
Much like other applications that display this banner while performing
a somewhat lenghty (by computing standards) process in the background,
I have the same need.
Is there a class that supplies the panel (banner) and methods to
determine when the background process has completed?
Thanks in advance,
Todd

- Bug or featureHi, can someone explain the behaviour of that snip
public class Test
{
public static void main(String[] args)
{
try
{
Class c = Class.forName("BUG");
}
catch (ClassNotFoundException e)
{
}
System.out.println("Everything works?");
try
{
Class c = Class.forName("NotbUg");
}
catch (ClassNotFoundException e)
{
}
System.out.println("Still works?");
try
{
Class c = Class.forName("bUg");
}
catch (ClassNotFoundException e)
{
}
System.out.println("Everything works!!");
}
}
class BUG
{
}
In not works on JDK 1.4.2 but JDK 1.1.4. Bug or feature that question is.
Thanks in advance.

- Hashtable qWhen traversing an Enumeration of Hashtable keys, I know that modifying the
HT can cause problems. But is doing lookups okay? E.g., in the following
code:
<assume ht is a reference to a Hashtable object>
Enumeration e = ht.keys();
Object o;
while(e.hasmore()) {
o = e.next();
System.out.println(o + ": " + ht.get(o));
}
Is this guaranteed to print out all of the key-value pairs?
