- Looking for Feedback on New Project - ChaiDBHi,
I'm one of the developers working on a new project: ChaiDB.
I am trying to get feedback on it, and looking to see if there might
be a good fit for your projects. We're currently exploring ways we
can add functionality to ChaiDB such as an indexing mechanism for
caching web data. I would appreciate any feedback/advice I could get
from this group and if you are interested, you can find details at
http://chaidb.sourceforge.net Below is a brief description of the
project.
ChaiDB is an embedded database developed at the kernel level using
Java and B-Tree implementation for data storage. It's very simple to
use without any administrative overhead for high performance read/
write operations. It provides Java, JCA, JTA interfaces and database
administration tools such as backup and restore, etc. ChaiDB is ideal
for applications utilizing caching, archiving, queuing and buffering
capabilities.
Thanks,
Jim

- Recommend a good programming environment for beginner?Howdy. I'm taking a java class, and they unfortunately just have us
using the DOS cmd liine and notepad to program. I'd like to use a good
environment. I used to use Codewarrior. Netbeans came with the Java
download from Sun, but it overwhelmed me, seems like I'd have to invest
a lot in learning it. Does anybody know of a sleeker, easier to get
used to environment?
Alternatively, anyone know of a good, simple, easy to follow tutorial
to get one up an running in netbeans?
Thanks a heap....

- Creme 3.27 and AWT framesHi!
I working on a problem. We have an application in which a signature can
be captured. This works perfectly on a PDA (Windows CE, Creme 3.25) but
since the upgrade to Windows CE Second Edtion, Creme 3.27 it fails to
work.
The problem is, the created frame will not be shown after the
frame.show() method. It looks like this thread is killed because the
code after the frame.show() isnt executed.
The (partial) code:
frame = new Frame();
frame.setBackground(Color.white);
frame.setSize(dimension);
saveButton.setLabel("Save");
saveButton.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e)
{
saveButton_actionPerformed(e);
}
});
frame.add(saveButton, BorderLayout.NORTH);
clearButton.setLabel("Clear");
clearButton.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e)
{
clearButton_actionPerformed(e);
}
});
frame.add(clearButton, BorderLayout.SOUTH);
frame.show();
frame.addMouseMotionListener(this);
frame.addMouseListener(this);
frame.addWindowListener(this);
}
//////////////////
frame.pack() before frame.show() doesnt help, frame.setVisible(true)
instead of frame.show() doesnt help. Anyone an idea ?

- JDK BSD NewBeeHi all,
I'm a BSD newbie with a couple of simple questions.
Does the 1.4 jdk implementation implement the hotspot optimizer? And
are the threads green or native - and what is the difference? I've
read that the jdk1.3 binary does not implement hotspot and uses green
threads and I'm trying to decide if upgrading to the jdk 1.4 will
improve my servlet application's performance.
Also, I've noticed that there are ports for things like tomcat and
other java third party extensions. Can anyone tell me the difference
between the ports version and those that I would download from say
jakarta.apache.org? I've compiled mod_jk from the apache source using
the mac os X compile instructions, as those were the only that I could
get to work, will my compiled mod_jk work better if I use the ports?
I'm new to the ports system as I come from the land of RedHat LInux and
Mac OS X.
Thanks for all of your help.

- Robot.java low level help followupMy quest to emulate Robot.java in C# continues......
I was not able to use SendKeys, SendInput, keybd_event, or the
WH_JOURNALPLAYBACK hook to reproduce Robot.java's key sending ability
for apps that poll the asynch key state.
Since I was not able to get any info about the low-level code
Robot.java uses to execute the keyPress and keyRelease methods (any
info still appreciated :) ), I ended up creating a java app that runs
minimized that has a socket to accept keys, and uses robot.java to
send them. Any app of any kind can send the keys to this app and
utilize Robot.java's functionality.
Hope this info helps someone looking to use the wonderful Robot.java
in another platform.

I didn't quite understand. Let me clarify what I said, just in case you
thought I was talking about something people do every day with Eclipse:
I meant it's virtually impossible to create a _whole_ workspace (with
Eclipse, plugins, projects, settings, just press play on tape...)
programmatically. Individual project settings (and a lot of them) can be
commited to version control and many typical settings work out of the box
after checking them out.

I have never written anything under the jre/jdk directory. The whole
thought of stabbing installed software makes me feel sick :)
Fortunately, I don't think there's ever any need for that, either.

- stable java environment on FreeBSD 5.2-RELEASE
--lrZ03NoBR/3+SXJZ
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Content-Transfer-Encoding: quoted-printable
Hi freebsd-java@,
I would like to setup a stable java environment on a FreeBSD 5.2-RELEASE
system. The primary goal for this is to coding java programs with
eclipse. I have read all information I found on google.com and
freebsd.org/java, but I don't get all answers for the questions I have.
;)
I had tried the installation of jdk-1.3 but the only version I get to
work was the 'linux-sun-jdk1.3'. I am a little bit confused about these
many versions around. So here are the questions. :)
1. Which JDK you'll prefer on a 5.2-R focused on stability?
2. Which steps are needed to install the prefered JDK?
3. Are there issues on the threading model (kse||thr)?
best regards,
Gordon

- Changing the value of Boolean?Sure I've read somewhere (but can't find it now) that you cannot change the
value of a Boolean tyep variable. You have to set it each time like this -
////////////////////////////////////////////////////////////
Boolean b = new Boolean(true);
b = new Boolean(false);
////////////////////////////////////////////////////////////
Is this correct?

java-programmer, WebSphere 4.0 and Visibroker
I have written an application that uses Visibroker to communicate with
a remote CORBA server. I have put the vbjorb.jar and other required
JARs under WEB-INF/lib. However, since vbjorb.jar contains classes
also contained in rt.jar, I also add the WEB-INF/lib directory to ws.ext.dirs.
This WSAD configuration works just fine. This is WebSphere 4.0
application.
However, when I attempted to deploy my application to WAS 4.0, I
persistently got a NoClassFoundError. Adding a ws.ext.dirs system
directory specifying the directory containing the JARS didn't yield the desired
effects. Even specifying the absolute directory path did not work.
Is there some other "trick" in order to deploy such an application
successfully to WAS 4.0?
Thx!

- java.util.Properties strange behaviourHello all,
I am facing a weird problem with java.util.Properties. I am trying to
store the Log4J configuration from a Properties object into a file
using Properties.store(OutputStream) method.
All the key-value pairs are written properly to the file except for
one: The JDBC URL.
This URL is of the form
jdbc:postgresql://my_server:myport/dbName
When this URL goes into the file, it becomes
jdbc\:postgresql\://my_server\:myport/dbName
The colons (:) get escaped. I dont know why this is happening, but
this URL is simply not recognized as a valid URL by Log4J when
encountered. How do I get rid of this problem ?
Please help.
Thanks in advance.
Best regards.

- Struts & Scaffold questionHi !
I've started to explore struts recently and now i'm looking into Artimus
example . So what i see is that through all this aplecation a lot of
Jakarta Commons pacages are used and one of them is Scaffold . It hides
original struts implementation . So i bump into several questions is it
common practice to use this pacage or there there are a lot of
alternatives or it's more recomendet to use struts and write my own
implementation. If Scaffold is a good thing to use where can i found
more matireal about it ?
Thanks a lot in advance !

- Determining interface implementations during runtime ?Hi All,
Hope all is going well!
I was wondering if anyone had any ideas how I might be able to determine
reasonably efficiently what implementations of a given interface are
available within the current scope of available jars/classfiles during
runtime in my application?
Anyone done something like that before using reflection or similar?
Any ideas/etc appreciated.
Cheers,
Marcus

- J2ME: Transferring RMS Data from Emulator to Mobile DeviceWe are planning to use the RMS to store our mobile application's
resource data (plain text), which are mainly used for populating the
drop downs (a.k.a. Choice Group) in the GUI. We have a lot of files
that need to be deployed with the mobile application. One of them has a
size of about 300K! It is fast to just download the file(s) via http.
However, it takes a very long time to process the downloaded data. By
"process", I mean by first storing the downloaded data in an RMS record
store and then place the data to different RMS record stores according
to certain criteria. We do this "process" because the requirements
state that we cannot show hundreds of data item in the drop downs at
any given instance for the sake of usability.
I would like to know if it is possible for us to use the J2ME emulator
to first load the resource data into the emulator's RMS, and then
deploy the emulator's RMS to the mobile device. If possible, how to do
it?
Thanks!
Simon.

- Pros and Cons of Static MethodsOkay, I'm in a debate over whether or not static methods are a good idea in
a general domain class.
I'm personally not a fan of static methods but we seem to be using them to
load an object. For example if you have an Employee class rather then
instantiating an instance you call a static method 'GetEmployees' and it
returns a List of Employee objects.
I'm looking for what other people are doing and if you feel this is a good
or bad idea.
Thanks

- JBoss/Tomcat or sth else?I greet,
(sorry for my english language + translator)
In relationship from this that I would like to learn to programme in
J2EE my
question is such:
I from what server should begin science JBoss / Tomcat or another one.
It what server was it been proper was to learn at the beginning if in
I would like to look for near future work as programmer Java.
Programming J2SE, applets is me already familiar { in some part
obviously). And even dust already first (rather successful) start take-
off from J2EE /
JavaMail :P and I tried to create own JSP + servlet'y.
As well as second question, what technology/framework to learn on
beginning and what of them are uses in work. I read recently
post that it does not it bribe to learn Struts'a because oneself him
already rather it
it uses.
Spring, Struts, Seam, Hibernate, JSF, EJB3.0, SOAP, RMI ... ?
I will add that they wake up that the technology of realization be

- Can someone explain this to me?Hello,
I have a very strange problem here. I have found the solution, but I would
like to know what is happening.
I load a file from a JAR file, using the following code :
InputStream stream=this.getClass().getResourceAsStream(name);
if (stream!=null)
{
int size=stream.available();
byte data[]=new byte[size];
stream.read(data);
}
stream.available() returns the correct size, the size of the file in the jar
file (0x1610E).
But the above code does not work! Only the first 0x3111 bytes of the stream
are read, the rest of the array is still 0!
But it works if I do the following code !
int c;
for (c=0; c<size; c++)
{
data[c]=(byte)stream.read();
}
Could it be that the stream cannot handle such a massive data output at
once?
Have you got any idea about this?
Thanks!

- Cannot load image in applet after placing it in a packageThis has been a much discussed topic in several newsgroups, but I still
cannot figure it out.
I got this class: htmledit.class. Normal website linking to this class as an
applet. Several image files (gif&bmp) for toolbar images.
/
| -htmledit.class
|
|-image1.gif
\-image2.gif
Applet loads, no problem. images are used in the toolbar. Applet tag calls
"htmledit.class"
Trying to get the class in a package (due to OO reasons and java 1.4 jdk) I
get:
/
|-/main
| \-htmledit.class
|
|-image1.gif
\-image2.gif
Changed the header of the htmledit.class to main package, changed the html
code to call the class "main.htmledit.class". Applet loads, get null values
from getResource() call. No images are loaded.
This applet is not (yet) part of a jar file. Tried copying the image files
to the main directory, add codebase, place them in a jar with archieve
attribute in the applet tag, calling image file with a "/" in front of it.
Why is the main applet class no longer able to access the image files when
placed in a package?

App on host2 does task Y
App on host3 does task Z
Only one app can do any specific task.
Now, if app on host1 shutsdown for whatever reason, either app on host2 or host3 should take over task X.
I was thinking of implementing this with UDP ... but someone may have already done this ... without using a database.
Is there a design pattern for the above ... basically a failover pattern ?
