###################end install.log###################
After downloading the .jar I used javac -jar on the file, and it launched
the installer window. I clicked all the appropiate buttons and the
graphical installer even said netbeans was now installed. The install.log
file disproves that, unfortunately.
what went wrong pls?
thanks,

PS: I posted this again to add "netbeans" to the subject line.

- Running compiled programs in command promptHi, I should know how to do what it says in the subject of this post,
but I don't. I've almost finished Sams Teach Yourself Java in 24 Hours
3rd Edition and now I need to pass some arguments to the program via
command prompt but the book only covers 1.4.
java program [arguments] when i cd it to the directory containing the
class
doesn't work.

- error starting java .jar app - classpath issue?I'm reluctant to post to a developers list, but this question
got no help at debian-user in the past 2 days. It seems to be
debian-related more than generic java-related.
This is likely a very simple issue. I've never tried to run a
java .jar library on debian before.
For all commands discussed below, no CLASSPATH environment
variable has been defined.
No errors if I switch to the .jar file directory and issue this
command:
$ java -jar tt.jar
But if if try either of the following commands from another
directory, the errors shown below commands appear:
$ java -jar /usr/share/java/tt.jar
$ java -classpath /usr/share/java/tt.jar -jar /usr/share/java/tt.jar
Exception in thread "main" java.lang.NullPointerException
at javax.swing.ImageIcon.<init>(ImageIcon.java:161)
at com.taubler.timebox.submit.SubmitExtensionWidget.<init>(SubmitExtensionWidget.java:16)
at com.taubler.timebox.submit.SubmitManager.<init>(SubmitManager.java:52)
at com.taubler.timebox.TimeTracker.<init>(TimeTracker.java:54)
at com.taubler.timebox.TimeTracker.main(TimeTracker.java:1115)
I wonder if it may just be a matter of learning how to correctly
set the CLASSPATH before issuing the java command on .jar
libraries held in /usr/share/java/. I could not find any
clear guidance about the usual CLASSPATH practice on debian.
(I run sarge. Java is from blackdown j2re1.4 and j2sdk1.4.
Installed without a hitch.)
(App in question is a timekeeper program. See
http://www.taubler.com/timebox/.)
Thanks.

- [Off-topic] cvsHello,
sorry for the off-topic question but I think this is a good
place to ask. I plan to develop open-sourced web application
which integrates CVS browser, a bug tracking system and some
more interesting features to support development both
open-sourced and commercial projects. I would like to know
whether it is worth to invest my free time for such a tool.
CVS is rather an old system and I have no idea how widely is
used in development teams. So my question is easy: Do you use
CVS in your development?
Thank you,
jozef

- Please test the new 1.6.0 patchsetAll,
If you're not afraid to build the JDK from scratch without a port,
please try the "current" (new) JDK 1.6 patchset (see
http://www.eyesbeyond.com/freebsddom/java/jdk16.html). This is based
on the 1.6.0 Update 1 Build b06 JRL source.
Unless I get some showstopper reports I plan to release this as
patchset 1 sometime next week. The raw patchset itself will have
problems if you don't have the /usr/X11R6 symlink, but this will be
fixed in the port.
I haven't yet created the jdk16 port, which is why you'll have to
build it from scratch ;). It should be reasonably similar to the current
jdk15 port though.
If the build is successful you should see something like this:
> /usr/local/jdk1.6.0/bin/java -version
java version "1.6.0_01-p1"
Java(TM) SE Runtime Environment (build 1.6.0_01-p1-glewis_19_may_2007_14_14-b00)
Java HotSpot(TM) Client VM (build 1.6.0_01-p1-glewis_19_may_2007_14_14-b00, mixed mode)
(This is on i386 -- you'll see the Server VM on amd64).
Note that I'll be out of town until Tuesday evening, so I may be unable to
respond to any problems before then.

- which data structure best fits this?hi,
i am looking for a data structure for fast retrievals... and here is my
scenario.
this table is about foreigncy exchange. i will have a buy currency,
sellcurrency, levels, and rate.
A transaction involves from a BUY currency to Sell currency, and it can
have multiple levels, meaning... if the sell amount is 1000, the rate
is 1.1, but if the sell amount is 2000, the rate is 1.2..etc...
Say there is a fixed amount of currencies that I need to maintain (say
10 type only) And I need to store all these rates in a structure, for
fast retrieval..
More concrete example.
Sell : USD Buy: EUR Level: 1 - 1000 rate: 1.1
Sell : USD Buy: EUR Level: 1000 - 5000 rate: 1.2
Sell : USD Buy: EUR Level: 5000 - 99999999 rate: 1.3
Sell : USD Buy: CAD Level: 1 - 1000 rate: 1.1
Sell : USD Buy: CAD Level: 1000 - 5000 rate: 1.2
Sell : USD Buy: CAD Level: 5000 - 99999999 rate: 1.3
Sell : USD Buy: GBP Level: 1 - 1000 rate: 1.1
Sell : USD Buy: GBP Level: 1000 - 5000 rate: 1.2
Sell : USD Buy: GBP Level: 5000 - 99999999 rate: 1.3
------ So, Sell for USD type is finished here.
Sell : EUR Buy: USD Level: 1 - 1000 rate: 1.1
Sell : EUR Buy: USD Level: 1000 - 5000 rate: 1.2
Sell : EUR Buy: USD Level: 5000 - 99999999 rate: 1.3
Sell : EUR Buy: CAD Level: 1 - 1000 rate: 1.1
Sell : EUR Buy: CAD Level: 1000 - 5000 rate: 1.2
Sell : EUR Buy: CAD Level: 5000 - 99999999 rate: 1.3
Sell : EUR Buy: GBP Level: 1 - 1000 rate: 1.1
Sell : EUR Buy: GBP Level: 1000 - 5000 rate: 1.2
Sell : EUR Buy: GBP Level: 5000 - 99999999 rate: 1.3
------ Sell for EUR is finished here.
so on with GBP, and CAD.
my requirements:
Say, someone tell me, what are all the rates for all the levels and
BuyType from EUR as sell?
Then that means I have to send back all the EUR as sell type.
Or, if someone say, what are all the rates for all the buytype for USD
from EUR as sell?
Then that means i have to send back all the EUR as sell, and USD for
Buy.
Or, if someone say, what are all the rates for all the buytype as GBP?
Then, i will have to send back all the buytype as GBP (including all
levels)
Or someone can just ask for a specific level as well for any buy type
of sell type, or both.
I was thinking about hash of hash... but if i have the Sell type as key
of the outer hash... then the inner hash will need to have a buytype as
the key... but then, i will have multiple levels...if i put the
multiple levels in an array of an object, and this object as the value
of this inner hash, that should be fine... but i am worry about the
speed.
Ideas?
thanks,

- Application StoppingI have an application I am working on that keeps shutting down. There
seems to be no rhyme or reason for the shutdown. It happens randomly.
Sometimes it will work other times it won't. I'm starting to think it
might be a windows problem, possibly a process that is running. As my
App is running, Windows thinks the program is not responding. No big
deal, but I'm starting to think that this might be the problem. Here
is the error code it is getting in the Event log.
Faulting application gl.exe, version 1.0.0.0, faulting module
msjava.dll, version 5.0.3810.0, fault address 0x000c4a7e.
It doesn't seem to have anything to do with memory, or the volume of
data I'm processing.
I don't know if anyone will have any advice, I'm grasping at straws.
I'm running Windows XP pro if that helps.
Thanks to anyone with any advice.

- Reading a line from a fileHi to all, I'm trying to read from a file, line by line, and parse out
the data, by using the line.split(" ") function, and I have a file that
has 8 entries total per line, which means that it supposed to read up
to , array[7], but for some reason, when I run it , it says array
outofboundaries. The only thing here that is to notice, is that the
value at 7 might be either a string or an empty string, can that be a
problem?
Thanks

- How to ignore invalid SSL CertificatesHi everybody :-)
I'm trying to build an application that serves as a Client Side
frontend for a webpage using HttpClient 2. Because I have some security
problems I decided that using https would be nice, but my SSL
certificates continue to fail validation and I'm wondering wether it is
possible to let HttpClient ignore Certification Failures? And if yes,
could you please give me a working example?

- It don't work with "PBEWithHmacSHA1AndDESede". What wrong?Hi.
In the following source, I got the exception :
"java.security.NoSuchAlgorithmException:
Cannot find any provider supporting PBEWithHmacSHA1AndDESede"
<source>
Cipher cipher;
SecretKey secretKey;
PBEParameterSpec parameterSpec;
try {
PBEKeySpec keySpec = new PBEKeySpec(password.toCharArray());
cipher = Cipher.getInstance("PBEWithHmacSHA1AndDESede");
SecretKeyFactory secKeyFac = SecretKeyFactory
.getInstance("PBEWithMD5AndDES");
secretKey = secKeyFac.generateSecret(keySpec);
parameterSpec = new PBEParameterSpec(salt, iteration);
} catch (NoSuchAlgorithmException e) {
} catch (NoSuchPaddingException e) {
} catch (InvalidKeySpecException e) {
}
</source>
The source above work with "PBEWithMD5AndDES". But, not
with "PBEWithHmacSHA1AndDESede". In the Sun's JCE API
Reference Guide, the "PBEWithHmacSHA1AndDESede" is the
standard name ( I use JDK 1.5 RC ).
What wrong? Thank you for your help.

- Is heavy client dead? Is swing applet dead?Today most Java UI developers are focusing on solutions like Struts,
Taperstry, and JSF. It seems that noone care about Swing applet as a
choice as rich client.
Is heavy client dead? I think heavy client solution like swing applet
is still good for business application. Especially for many internal
business projects. In internal business environment, the download speed
is usually not a problem. Swing also provides better GUI than html.
Swing has the ability to cache information on the client side which
save a lot of network calls to server.
Do you agree? Should we all forget about Swing and heavy client
solution, and vote for Struts and JSF?
Thank you

- Making the most of codeI have a web site that uses JSP and some back end classes to manage
data in a MySQL database. It does okay and has run well for about 3
years. It has, however, grown to the point where I need to redesign
some of it to be more dynamic. I've recently started incorporating
Hibernate and JavaServer Faces to ease the development now and make it
easier for me to make changes later on. Or at least that was my plan.
Each database table maps to a Java class. I will easily have 25-30
tables before I am done. I am okay with 25-30 classes to represent
the data, but my concern is when it comes to the associated classes
needed to manage the data connections and such. I find that I am
cutting and pasting way too much similar code into these separate
classes.
For example.
I have a HibernateDAO class that manages the Hibernate session.
Each class then has its own DAO class that extends the HibernateDAO
class and the code within the extended DAO classes is virtually
identical.
Here is one method from my clientDAO class.
public Client add( Client client) {
try {
begin();
getSession().save(client);
commit();
return get(client.getClientId()); //not every class
will have a clientId member
} catch (HibernateException e) {
rollback();
System.out.println( "Could not add client: " +
client.getClientId() + " : " + e); //message hard coded for client
class
return new Client();
}
}
And then in my ContactDAO class I have this.
public Contact add(Contact contact) {
try {
begin();
getSession().save(contact);
commit();
return get(contact.getId()); //not every class will have
an Id member
} catch (HibernateException e) {
rollback();
System.out.println( "Could not add contact: " +
contact.getId() + " : " + e); //Message hard-coded for contact class
return new Contact();
}
}
Note that the code is virtually identical.
The begin(), getSession(), rollback(), and commit() methods are all
from the HibernateDAO superclass.
I tried using Generics to make the return type and parameter <T>, but
this only gets me so far. I cannot declare a new instance of <T>, or
at least I don't know how to. And the method uses values that are
specific to the class in question. I.E. not every data class will
have a getId() method.
I am not sure if any of that made sense, but the crux of the issue is
I am trying to avoid cutting and pasting code and then having to
remember to update it in 25 different places when I make a change. I
feel like there is a way to do what I want, but I just don't have the
experience to see it.
If anyone can point me toward some documentation that might help set
me straight, I would appreciate it.
Thanks.

- Java SoundI am intersted in building an applet that can both play and record
sound files. I would like this to work on the widest range of platforms
(MAC, Linux, WinXP, WinNT, etc) and browsers. What would be the best
file format for the sound files to accomplish this? Would it be MP3,
WAV, or what? I am looking to have this work without any added packages
over and above JDK 1.4.x.
Thanks for any and all info.
