- Can javac do macro (conditional) compilation?In C/C++ we can do
for example:
#ifdef VERSION_1
// write version 1 codes here
...
#else
// write version 2 codes here
...
#endif
Then when we compile the code with -D option
gcc -DVERSION_1 input_filename.c -o output_filename
This will compile the codes in version 1
gcc input_filename.c -o output_filename
This will compile the codes in version 2
I am just wonder can I use -J option in javac?
If I can, then how do I write the syntax in java codes?

- Azureus wont compile coz of 4E4D4554484F440E4350500525Hello people...
So, after dodging Azureus dependancies, this might be the final hurdle
to get Azureus to compile :/
Anyway... I got an internal error (4E4D4554484F440E4350500525)
I got that error when I was installing something called "sed"
(/usr/ports/net/sed ?), but that got resolved once I mounted
linprocfs...
But Azureus refuses to compile...
I googled further more and one site tells me to add -Xint to my java
command line... I added that in the last line of work/azureus file
that was created. And thats how the number of files mentioned in the
output below reduced from 2000 something to 1476... Good thing/bad
thing???
Any ideas how to get this working?
Below from BEGIN to END is the exact console output...
PS: please CC your replies to me coz im not on the list....

- editing nodes in JTree, icon problemI have a JTree with a child node that has a dropdown list in it. When I
click on the node to make the list appear, then make a selection, the
icon changes to what looks like a document icon.
My problem is that the document icon stays there after I make the
selection in the dropdown list until I click on another node. It's like
the process of making a selection is unfinished.
Anyone know what that is?

- [struts] ActionForm design questionHi,
I've wrote a java application (not a web application) which containg
some bean used extensively in the application.
Now I would like to reuse those bean inside a struts based web
application.
In struts a bean supporting a form must extend ActionForm. I would like
to reuse the beans written for the first application. Is it possible in
some way???
The only way that i saw is to use Bean.Utilis.copyProperties in order
to copy a bean into another.

- Application wide variables with Tomcat/AxisHello,
I have installed axis on Tomcat and a few WebServices.
My Problem: I want to have a >>APPLICATION WIDE OBJECT<<, which you can
reach from a WebService as well as a Java Application which is running
on this server.
I would like to have something similar to the Session Object on a Web
Page where you can add and remove items.
Scenario:
-------------
The Programm Codes who share a Class called MyQueue, which is a Class
which holdes
all the processes.
WebService1(Pseudo Code)/**Fills Queque with new Datasets*/
public boolean fillQueue(int GUID, String ProcId){
MyQueue myqueue = getLivingQueue(); //This function shell give
me the actual queque,
//NOT a new one!!
MyQueueDataset oneDataSet= myqueue.create() ;//Create a new
DataSet
//in the Queue.
oneDataSet.setProcId(ProcId);
oneDataSet.setGUID(GUID);
oneDataSet.setStatus("InQueue");
...
return true;
}
WebService2:(Pseudo Code)/*Find out Status of certain Queque*/
public String getStatusOfGUID(int GUID){
MyQueue myqueue = getLivingQueue(); //This function shell give
me the actual queque,
//NOT a new one!!
MyQueueDataset oneDataSet = myqueue.getByGUID(GUID);
return oneDataSet .status;
}
A Job:(Pseudo Code)/*Try to proceed DataSets which havent proceede
yet*/
Class Watcher(){
int static main(){
...
MyQueue myqueue = getLivingQueue();
while(1==1){
ArrayList allJobsNotDone =
myqueue.getAllDataSetsWhichAreNotSuccessFullProceedd()
while(allJobsNotDone.hasNext() ){
MyQueueDataset notJetSuccesfullProceedeJob =
allJobsNotDone.next();
//Now we call a function which lets say try to put the values
//of notJetSuccesfullProceedeJob into a database.
proceed(notJetSuccesfullProceedeJob );
}
}
}
}
Is this possible just with Tomcat?
Do I need a Messaging System (JMS) or something?
I would appreciate help very much.
Thanks in advanced,
Peter

- unsigned shift confusionHi, I'm testing the unsigned shift operator in Java. Unfortunately, the
value I predicted for the output is 2^17 (131072), not 2^17 - 1
(131071). See below:
"""
class unsignedshift {
public static void main(String args[])
{
int a = -10;
String bs1;
a = a >>> 15;
bs1 = Integer.toBinaryString(a);
System.out.println(bs1);
System.out.println("The length of the binary string is " + bs1.length());
System.out.println("a = " + a);
}
}
"""
Output is:
"""
11111111111111111
The length of the binary string is 17
a = 131071
"""
Where is the difference of one coming from?
Thanks.

- Encrypt Text?What's the best method of text encryption if I wanted to store passwords in
an XML file? Are there any in-built functions of the API which would allow

java-programmer, Java Bytecode to Native executable to Protect IP
Hi
Looking for a java bytecode compiler that will compile java byte code to a
windows self executable file. Reason is to protect intellectual property. I
realise that JET may be able to do that, but the full version is not free
and seems too taxing on the hard drive space. So anyone know of a free
bytecode compile that is simple to use.
Thanks in advance

- Sun JVM and memory requirementsHi everybody,
For maximum separation of environment we want to run multiple java
instances (each running a webserver). now at peak moments I want these
to use the maximum heap, however, if the peak moments are passed, it
should free up the heap it doesn't use. Is this possible? Is it even
nessesary? What are the alternatives. I must be able to shut one JVM
down without it affecting the others.
Thanks in advance,

No. I had an editor, Brief. I didn't have lisp-syntax supporting editor
in 1988. The first syntax supporting editor I saw was Emacs in '91, I

- InvokeLater does not update in timeHi everybody,
I'm working on a small application that scans a lot of files for
information.
To let the user know what is going on, I update the following components:
- a JList containing log messages
- a JProgressBar indicating the progress in the current file
- a JProgressBar indicating global progress
The scan progress is a separate thread. I noticed that the JList was not
getting updated correctly, and after some Googling I found out that this
was because I was not updating it in the Event Dispatching Thread. So I
added the following piece of code:
--- code ---
if (SwingUtilities.isEventDispatchThread())
{
sv.showMessage(message);
}
else
{
Runnable run = new Runnable()
{
public void run()
{
sv.showMessage(message);
}
};
SwingUtilities.invokeLater(run);
}
--- /code ---
"sv" is the JFrame containing the JList. This would ensure that a) the
JList would get updated, and b) that the results would be displayed in
the EDT.
So far so good - but as a result of the amount of files, there will be
thousands and thousands of Runnables, each waiting their turn to get
executed.
The end result is a display in which both JProgressBars are both at 100%,
and the JList still is updating a list of what's going on.
How can I let the update process for the JList keep pace with the
JProgressBars?
Thanks in advance,
Ikke

- Web-Launched Export to PowerPointIntroduction and Objective
Chalkwaves is a partnership of 240 school districts, Missouri, Kansas
and Illinois public broadcasters and educational service centers. We
offer services that assist teachers in meeting learning objectives and
engaging students in meaningful learning experiences. Our instructional
video collections come in two packages; which can be purchased
separately or bundled together. Chalkwaves provides these services to
the schools via a proprietary software player and a web interface. This
RFP is for additions to the web interface.
The current software player has the ability to do what is called "export
to power point". This is the feature that we require to be programmed
for our web interface.
Goals:
1. To be able to play one of our videos ( which is already working on
the web launcher software) and click a button that will allow the user
to select a start time and end time in hours, min, seconds. Once the end
user has entered this information. A power point page is brought up with
windows media player embedded into a new power point presentation.
2. The use of javascript or the java language to accomplish this task,
rather then active-x controls.
Requirements:
1. The export to power point feature needs to actually embed a windows
media player object and not use the standard power point embedding
function. This is critical since the embedded player does not have some
of the features required to play properly.
2. The use of javascript or the java language to accomplish this task,
rather then active-x controls. Since the web was created to be platform
agnostic, we need to create this using software that is platform
agnostic. Active-x does not meet this requirement.
3. All source code will be delivered to KCPT upon completion.
4. We can send a sample of the player software that shows how this
feature works.
Provided materials:
1. A copy of the software program showing how the feature works.
2. Access to a web site for testing of the features.
3. Access to php programming knowledge about how the current web
launcher works if needed.
Application Process:
Please develop a document containing the following information and send
it to Amy Long (email***@***.com). The length of the proposal should be
three pages or less and include a time and price estimate.

If you don't want to use mouse functions, the way you discover
keyboard shortcuts is to click Help | Keyboard and they are all there
for you, including F2.
If you wanted to put F2 on a menu, you can reconfigure the menus.
There is not much point. You can click the address bar with the mouse
faster than you could a menu item.
If you don't like clicking new page to get started, you can configure
some dummy home page.
There are two sorts of problem with a browser -- initial getting

- JTable Display doesn't match TableModel ??Hi All,
I have a Jtable & Tablemodel.
When I clear the tablemodel, rows in the JTable are still visible, what
am I missing ?
TIA
Bill
// clear the data
datalist.clear();
fireTableDataChanged();
// rows are still visible in theJTable !!!
.....do lots of processing to get more data....
// at the end of all the processing - change the data in the model
datalist.clear(); // initialize the list
datalist.addAll(list); // add the data
fireTableDataChanged(); // fire the data changed event
// now the JTable matches what is in the Tablemodel..
