- vector.containsIf I write a class and have a vector containing various instantiations of it,
and I want to see if the vector contains another,i.e.
theVector.contains(theClass)
What do I need to overload/write/tweak to make sure "contains" finds the
vector element if it is equal to the "theClass"?
Is there some method I add to myClass to make the contains work?
Thanks

- Novice Java Pasters question / conflictsI have been experimenting with several java and javascripts on my website. I
was doing pretty good until I notice that the script to display the time had
vanished. I tried running this on a fresh web page and it worked. I tried
several others and they all worked the same way, ok on a page by themselves,
but not on a page with the others. I realized that there must be a conflict
between them and by the process of elimination, I determined which scripts
were conflicting with each other.
Here are the 2 scripts that refuse to run on the same page together:
Dynamic Day'n'Night Worldmap by Urs Dudli and Peter Gehrig
http://www.24fun.com
and
The JavaScript Source: Clocks: Universal Clock
The JavaScript Source!! http://javascript.internet.com
<!--By: Rakesh Jain (email***@***.com) -->
<!-- Web Site: http://www.bhabus.com -->
I believe that day n nite is the main problem because I tried several clock
and date scripts with it, and none would work except without it, [or on
pages by themselves]
Could anyone on this group know what causes this, if there is a cure, or
another group to try? I'd really like to have them both work!

- Trees in javaHi !
Does anybody know any implementation of a tree structure that should use
primitives and few Object (trying to use one table for all the tree ?).
I want to create a word dictionary by factorizing common letters. At the
moment, each node is a letter with a Hashtable to list the chidren. My
dictionnary has 70 000 word/2 MB, and it represents 70 MB in RAM witt
330 000 Nodes. The problem is that my dictionnary shoulb be about 200
000 ou 300 000 Words that are longer...
Can somebody help me ?
Thanks !

- Help with web services client codeI think I have successfully deployed a web service with Axis, but I can't
figure out how to test it.
Here's the WSDL document:
http://www.public.asu.edu/~wsmoak/xml/webauth.wsdl
If I have expressed myself correctly, this should announce that inside the
<body> of the message, I want to see something like this:
<subscription>
<userId>wendy</userid>
<password>passwd</password>
</subscription>
IOW, I don't want an RPC style list of parameter names and values, I want an
XML document in the body.
The client code I'm playing with is here:
http://www.public.asu.edu/~wsmoak/xml/SubscriptionClient.java
Either the client code or Axis is still uncooperative... if I manually
construct the XML above in the body, Axis insists there is No such operation
'subscription'. So maybe I haven't deployed it correctly yet. :(
Can't say I'm having much fun yet! This reminds me of getting started with
Struts... sparse documentation, very few examples that matched what I was
trying to do. Give it a few months and I'll know what I'm doing, right now,
I'm LOST!

- free java datetimepickerhi,
if you need a datetimepicker-control for java,
you can find one on my side:
http://www.software47.de/eng/software/datetimepicker/datetimepicker_en.htm
it's absolutely free, you can use it as you like.
since i was looking for a free datetimepicker myself, but found nothing, I
wrote one the last days...
If you find bugs or have ideas to better it up, let me know.
Java 1.4 is needed! (because of frame.setundecorated...)

This is a problem of the GCJ installation on the system. in Etch
libgcj7-awt is recommended by gij which is not very likely to be
installed by the local admin as we tell users to install
java-gcj-compat. In Sid/unstable we solve this by letting
java-gcj-compat recommend libgcj8-1-awt. As we depend on users
installing recommendations that is no problem. This is *no* problem of
freeguide. Its discussable if we should add a recommends on libgcj7-awt
to java-gcj-compat in stable. But thats a decision to be made by the
stable release managers.
Cheers,
Michael

- How come DefaultTreeCellRenderer's behaviour changes when called from different directories ?!?Hi,
I use the following lines in a TreePanel class I've written:
> DefaultTreeCellRenderer rend = new DefaultTreeCellRenderer();
> rend.setLeafIcon(null); rend.setClosedIcon(null); rend.setOpenIcon(null);
> tree.setCellRenderer(rend);
to see to it that when displayed, my tree will be as plain as can
be (no icon at all, no default small picture on the line where you
click to expand the node etc.).
When I use this class with a certain app., it works, I get what I
want, the tree appears in a thin black dotted line, with a little
squares containing a '+' sign when the nodes are closed, and a '-'
when they're expanded; but in another app. (I use THE VERY SAME
CLASS, the same .class file) instead of the small square with '+'/'-'
I have the Sun default small picture of a node you see ?, a tiny
circle with a dot in its middle and a little hyphen, and the line
is blue pale.
Anyone can explain me this behaviour ??
Thanks...

Spendius

- Jan 8, 2006 session bean questionI have a design issue. I am working on making a J2EE application as
training/practice. I will have a GUI client as a that allows users to
login, register, deposit etc for a bank. At the back end I have a
database with currently 3 tables and above that 3 Entity EJBs to
represent the tables (trying to keep this simple). The Entity EJBs are
customer, checking, savings.
Now in between the GUI client and the Entity EJBs I plan on having
session EJB(s).
My Q is should I have (a) session beans for each type of business
transaction such as "register", "deposit", "withdraw" or should I have
(b) one session bean with methods such as "register", "deposit",
"withdraw"? Does it make a difference?
Thanks for all advice.

- How to structurre the GUI for this MetronomoHello,
I have necessity to realize a metronomo in java,
it is also an occasion in order to understand something of user
interfaces considering that until now I just be occupied in J2EE.
I have to use use java.swing.Timer in order to color one of N circles,
the problem is that N it is defined from the user and unlimited so I
don't know how to arrange this in a modular project.
My idea is the following:
Frame with:
BorderLayout South a JPanel with the inputs for metronomo
BorderLayout Center a JScrollPane in which to design all the circles
but I don't know if it is best to design every circle in a different
Jpanel, I do not have clear ideas, someone can give me an help on
structuring this application?
Thanks

java-programmer, Java Delegate and Visitor Pattern examples ...
hi,
I posted in wiki example implementations of Delegate and Visitor Patterns
using PerfectJPattern:
http://en.wikipedia.org/wiki/Visitor_pattern#Java_Example_using_PerfectJPattern
http://en.wikipedia.org/wiki/Delegate_(.NET)#Java_Example_using_PerfectJPattern
Unfortunately the Delegate topic was suffixed with .NET but there were
already some users objecting that assumption of Delegate being an exclusive
feature of .NET
I hope these examples are helpful and any feedback will be welcome.
best regards,
Giovanni

- Storing a sound as an objectHi,
I'd like to load a sound file, store the sound as an object, and then
play it back at some later time. What are the classes appropriate
for that scheme? I have a lot of experience programming Java, aside
from audio, so really all I need is a pointer to the right approach,
and I think I can figure out the rest.
Thanks for your help. I found a lot of stuff about Java audio
programming,
but I didn't see (or couldn't recognize) a solution to this problem.

Those numbers sound suspiciously like a DNS timeout. Do the
machines know about each other? That is, do they each have
DNS entries or entries in each others host files?
Even if the originating machine uses an IP address rather
than a name, the destination could be attempting a reverse
DNS lookup, IP to name. It sure sounds like your network
configuration, however.

- SWT and SVG in standalone bpplicationHello!
I am developing a standalone application using the SWT framework;
however, the application will not be based on the eclipse rich client.
I like to integrate SVG graphics into my application; more precisely, I
would like to render SVG graphics to arbitrary positions on a Canvas. Is
there a convenient way to do so? I already checked the Apache Batik
project, but this one does not integrate with SWT. The Holongate project
does only provide plugins for Eclipse, which I can not use when I do not
use the Eclipse platform.
Thank you for hints!

Yes and no - even if the original poster is a cheater type, a good

Also true, but if they are such, they will come back to the well if they
get good, but insufficient, information.

an input type as "file" and made it hidden. i have then called it
using a bit of java script ( uploadObj.click(); )linked to my image,
used to represent the button.
Problem occurs when you go to submt the form. IN IE, running on xp
home, with service pack 2 installed, it empties the textfield. THe
file must be put through as type file, so filling a textfield with the
text is not allowed.
I have included a reduced version of the problem in the code below ( i
have made the file upload visible for test purposes)
<html><head> Form Test </head><body>
<SCRIPT LANGUAGE = "JavaScript">
function BrowseForFile() {
var browseObj = document.getElementById("thumbNail");
browseObj.click();
}
</SCRIPT> </body>
<form Action = "here.html" name="myform" method="post"
enctype="multipart/form-data">
<a onClick="BrowseForFile();">Browse</a>
<input type="file" name="thumbNail" >
<input type="submit" name="sub" value="send now" >
</form>
</html>
Notice how using the default browse button and pressing "send now"
posts the form off to the location requested.
Now try pressing the browse text to the left, upon selecting the file
and pressing the "send now" button it simply empties the text field,
WHY???
Thank you in advance
