- Please help for a LinkBinaryTreeInJavaI am new in this group,I don't know how far it would help me.
I tried to make a linked based binary tree following the book "data
structures and algorithms in java" By goodRich and tamassia.I did all
but I wanted to implement a function to determine whether a particular
node exists or not.All I want to implement a function boolean
exists(node n).Can anyone help??My program is as follows:-
import java.io.*;
interface Node {
Object getData();
int getID();
}
class TreeEmptyException extends Exception {
TreeEmptyException(String message) {
super(message);
}
}
class LinkBinTree {
BinNode root;
int size;
LinkBinTree(Object O) {
root = new BinNode(0);
}
class BinNode implements Node {
int id;
BinNode left;
BinNode right;
Object data;
BinNode(int iden) {
id = iden;
left = null;
right = null;
data = null;
}
BinNode(Object O) {
id = 0;
left = null;
right = null;
data = null;
}
public Object getData() {return data;}
public int getID() { return id;}
void addLeft(Object obj) {
BinNode b = new BinNode(obj);
left = b;
}
void addRight(Object obj) {
BinNode r = new BinNode(obj);
right = r;
}
BinNode addLeft(Node n,Object O) throws TreeEmptyException
{
if(!exists(n)) throw new TreeEmptyException("Tree doesn't
exists");
return n.addLeft(O);
}
BinNode addRight(Node n,Object O) throws TreeEmptyException{
if(!exists(n)) throw new TreeEmptyException("Tree doesn't
exists");
return n.addRight(O);
}
void preOrder(Node n) {
LinkQueueApp<Integer> q =new LinkQueueApp<Integer>();
int p=n.getID();
q.enqueue(p);
while(!q.isEmpty()) {
p =q.dequeue();
System.out.println("The pre-order is : "
+n.getData());
for(int i=p;(i==p+1) || (i==p+2)&&i<=size;i++)
q.enqueue(i);
}
}
void boolean exists(Node n) {
if(Node == root) return;

- MVC Framework for Swing?Hello:
I'm looking for an MVC framework for Swing apps. I'm thinking of
something similar to Struts, but for desktop apps. I keep on writing
controllers for each Swing app I develope, and I can't believe there's not
a framework out there to expedite this.
Has anybody invented this yet?
Thanks

- Blog Musing: "contextual usage patterns"An interesting post by Andy Roberts, CTO of Bowstreet.
"One of the things lacking with any OO programming language like Java is the
idea of capturing 'contextual usage patterns'. By this I mean the ability
to capture the essence of how an object is to be used in the context of
various environments. I use the term "contextual usage pattern" to mean the
usage pattern of an object in some context....

- dragging graphics in a JTableI am interested in creating a graphics object (for example, a big dot)
creating it such that it can be moved within a cell and then moved
across cells. I had something working outside of a JTable (using
Point2D) and overiding paintComponent such that the drawing routine
looks like:
public void paintComponent(Graphics g)
{
super.paintComponent(g);
Graphics2D g2d = (Graphics2D)g;
g2d.setComposite(makeComposite(.5f));
}
I have two questions at this point. First, is it feasible? and Second,
if feasible, how would one generally go about it (custom editor, firing
events when it the object gets near a cell border, etc.?)?

- How to disable automatic scrolling of JScrollPane / JTextPane (Swing)Hi,
I want to be able to enable / disable the automatic scrolling performed when
adding text to a JTextPane. A JScrollPane has a viewport set to the
textpane. The text is added within a thread invoked using
SwingUtilities.invokeLater(...). Only the automatic scrolling should be
disabled, the user must still be able to scroll using the scrollbars etc.
and be able to enable the automatic scrolling again. (I'm using
jdk1.5.0_03.)
Here is how some parts my code look like:
...
<init>
...
jTextPane = new JTextPane();
JScrollPane jScrollPane = new JScrollPane();
jScrollPane.setViewportView(textPane);
...
<some-method>
...
StyledDocument styledDocument = (StyledDocument)jTextPane.getDocument();
...
<call addText-method>
...
<addText-method>
...
Runnable r = new Runnable() {
public void run() {
try {
styledDocument.insertString(styledDocument.getLength(), text,
style);
} catch (BadLocationException e) {
e.printStackTrace();
}
}
};
SwingUtilities.invokeLater(r);
...
Every time the <addText-method> is called the JScrollPane scrolls to the end
of the document. How can I enable / disable that automatic scrolling and
still use a thread / invokeLater to add the text?

- data synchronisation - java server side or www server side?I develop the application, which consists of the following:
- java server module (database connection, query execution, data update)
- www server module (www clients handling, data exchange with java server)
- many www clients (changing data, and need to have all data updated, so
synchronisation is required)
The question is:
To decrease the need of working with database and network load, where should
I keep
synchronised data taken out of database? At the java server side or at the
www server side?

- Learning J2ee, got newbie question.Hello. I picked up a Beginner's J2ee book. I'm going through the
examples, but one of the examples I am stuck on. I cannot get past the
error message:
404 - Resource Not found.
I am running Tomcat, I believe 5.5.8. Here's the directory structure
that I have:

Here's the login.html:

My browser complains that Login resource is unavailable. Here's
Login.java, which is compiled and in the same directory.

} catch( Exception e) {
e.printStackTrace();

Anyways, does anyone know what I'm doing wrong here? (I just typed the
example pretty quickly, so there might be typos, but the above compiles
without complaint.) Thanks.

- "package own.examples": necessary for NetBeans?Hello together
I am learning java and for my beginning, I just used a simple editor to
write the example codes. Now I wanna try NetBeans, but unfortunately all my
codes aren't working! I found out, that NetBeans need at the beginning of
the source file: "package own.examples" (i.e. where the source is stored).
Of course none of the sources I've written contains this add-on (because I
didn't need it). So they don't work with NetBeans. Why? If I am adding this
small "sentence" to the source code, I can compile it with NetBeans without
any problems, -> but not any longer with the command prompt (I am using
WinXP Pro at the moment).
What am I doing wrong? Is this sentence really necessary? I am asking,
'cause I want to implement a CMS (maybe JSF or Struts) and therefore I want
to know:
1) if it is better to use Eclipse or jEdit (do they need this extra
sentence, too?),
2) and if I am using an Application Server, it always needs "package
own.examples" or not? (so that maybe it is better not to use NetBeans 'cause
of this "lack")
thanks and cheers

java-programmer, JTable cell selection event
Greetings,
I have an application that uses a JTable. When the user changes the
value in one of the cells and moves to another cell (with either the
mouse or keyboard), I want to do something with the new value of the
changed cell, any idea how I can capture this event?
Thanks in advance,

java-programmer >> JTable cell selection event
You must implement this method (in table model):
public void setValueAt(Object val, int row, int col) !
Whenever user exits the cell, this method is called.
Does it works?

java-programmer >> JTable cell selection event
You can use the quicktable verison of JTable, it generates an event
whenever a user modifies a cell and exits the cell. You have the
option to accept the user changes or set a new value to the cell.
http://dbtable.hypermart.net/doc/quick/dbtable/DBTableCellListener.html
java.lang.Object cellValueChanged(int row, int col, java.lang.Object
oldValue, java.lang.Object newValue)
For more information have a look at QuickTable
(http://dbtable.hypermart.net)
Cheers,
Liz.

Thanks Liz,
That sounds like just the job - I'm new to Swing, and coming from a
Delphi backgound (all bow), I find it frustratingly difficult to
accomplish what ought to fairly straightforward tasks such as this.
Thanks Again,

- How many JRE versions are OK?I have a 2 year old HP notebook running XP HE that has two versions,
1.3.1_03
1.4.2
of the JRE installed on it, and I have two questions.
1. The older version was installed when I bought the
notebook, and the
1.4.2 version was installed when I installed
StarOffice. Is there any
reason to keep the older version, or should I
un-install it? I do not know which app, if any, uses this older version.
2. A new application that I use, wants to install a
slightly newer
version,
1.4.2_03
How should I do this, i.e. should I un-install either
or both of the
older installed versions first or install a third
version? FYI, the
installed 1.4.2 version does not have an Update tab.
I noticed that some info at
http://mindprod.com/jgloss/flipping.html
suggested that more than version should not be installed. My guess is
that StarOffice will work with something newer, i.e. 1.4.2_03 or even
1.5.1.
Thanks,

- Plotting 2D grpah in JavaI was wondering if there is some package available that can plot 2D graphs
in Java? I have developed a piece of software whcih simulates behaviours of
models and at the moment I save the data to file and use Excel to view it.
I was hoping to interface something directly with my Java program to view
the results. Is there anything out there?

without invocation of JVMPI and makes dump only when exception occurs.

- Java Component SchedulingIn my system I have a java component which I want to activate only
within a certain time window.
It is a distributed system consisting of a jobproducer which hands out
tasks to the workers. Each worker runs on a different host. I want a
worker to start up and process jobs only if the time is right.
I am currently thinking along the following lines:
- pass in a time-window argument to the worker program e.g. 1900-0600
(7pm to 6am)
- if the current time is valid, it registers with the job producer and
starts receiving/processing jobs
- if the current time is not valid, it sleeps for a bit and tries
again.
- after completing a job, it checks whether it can take on another job
at the current time. If it can't it sleeps.
I don't really like the idea of the sleeps. I also don't want the
producer to be burdened with the task of activating workers at certain
times. Is there a better way?
Does anyone have any experience of doing something like this? Any help
would be appreciated.

?Converting the EDI 96A Message Type to an XML document.
?Using the Stylus Studio XSLT Mapper to get the converted XML
into a more formal XML standard.
?Using the EDIFACT to XML Schema wizard to generate an XML
Schema based on the EDI 96A Message Schema.
?Configuring the EDIFACT to XML Schema Wizard.
?Browsing a converted EDIFACT data model in the XML Schema
Editor.
?Validating a converted EDI document against an XML Schema.

stupid as setting the col value as the row value and vice versa
well there went my day anyway :)

- Outputting value of variable during executionI am using word pad to write the java codes.
Suppose i need to find out the value of a certain variable during execution.
What's the best way to do it? I am clueless.
I have many classes in my java program and I don't suppose I have to pass a
Label member to each class constructor, just to output the class variable to
the Label.
btw, in VC++, I may just use a messagebox to show the value, simply.
Hope I am clear. Thanks.

Newbie

java.util.ArrayList, don't use java.util.*, why we have to do this.
just for good code style ? or ....

- Vista/Java security test - applets/jwsBugs reported* against Java under the new Vista/IE
security model affect signed applets, and also
trusted JWS applications.
<http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6548078>
<http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6504236>
The basic gist is that Vista imposes a more
restrictive security environment (particularly
to do with file access) than the original
trusted app. would receive.
It had earlier been noted that some JWS/browser
interaction problems can be sorted by 'disconnecting'
the launch from the browser and any security model
it might impose, so that led me to wonder if a new
ability of the JNLP API's BasicService in Java 6 might
help here.
The BasicService.showDocument(URL) method will
normally show the URL in the user's default browser,
but Java 6+ will hand an URL for a JNLP file
directly to javaws.
So I have a test..
Here is an unsigned web start application that
should not be affected by the bug.
<http://www.physci.org/jws/jwsapp.jnlp>
It is intended to display details of launch files,
and also offer to launch them - so it is running as
Java 6+.
Here is a *signed* web start app. that requests
full permissions, if launched from IE, it should
trigger the bug..
<http://www.physci.org/giffer/giffer.jnlp>
However, if my theory is correct (I don't have
access to machines running Vista), the first app.,
the launcher, should be able to launch the second
app., the Gif encoder**, just fine.
** Or it's 'big brother' listed below it..
<http://www.physci.org/giffer/giffer0512.jnlp>
Can anyone with Vista tell me if it works to
get around this bug, by launching trusted JWS
apps. directly from a sandoxed JWS app.?

- No X11 DISPLAY variable was set, but this program performed an operation which requires it.Hi all,
I am trying to run my program on the server. I connected to the server
through ssh and typed the run command. But I get the following
message. This is the first time that I tried to the program in my
laptop, so I don't know what's going on. Could anyone please let me
know what is going on here and suggest how to solve that problem?? I
am using Fedora Core 4. And the program that I am trying to run is a
java program with RePast simulation package. Thank you.
