- Ant multi OS <exec> adviceHi,
I have the following Ant code which I would like to also use on Linux:
<target name="build.XmlJaxb">
<exec dir="${checkout.dest}/XmlJaxb" executable="cmd">
<arg line="/C ant -logger org.apache.tools.ant.XmlLogger
-logfile ant_log_dist.xml dist" />
</exec>
</target>
For Linux I woul dneed to replace "cmd" and "/C" with "bash" or something?
I know there is the <exec> OS option but then I would need to copy the
<exec> tags with a Windows and Linux version. Gives maintenance errors.
I know I could make variables for "cmd" and "/C" and use the <if>
contrib to look at the os Java system property.
I cannot use <ant> task because I do not seem to be able to specify the
Xml logger and the output file.
any ideas?
thanks,

- 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 ?

- JSP upload - detecting file type by mime type? what is application/octet-stream?I'm uploading a file via servlets or JSP, using the O'Reilly
MultipartWrapper, and was hoping that to be able to determine the file
type (eg. Excel spreadsheet, Word document, Powerpoint, PDF) depending
on the Mime Type.
Simple enough using the O'Reilly servlet package ~
<%@ page import="com.oreilly.servlet.*" %>
<%
if (request instanceof MultipartWrapper) {
try {
// Cast the request to a MultipartWrapper
MultipartWrapper multi = (MultipartWrapper)request;
// The file upload field on the submitting form is called
'upfile'.
String mimeType = multi.getContentType("resourcefile");
...
%>
Strange thing though is that I'm not getting the expected Mime Type.
For example, I just uploaded a Microsoft Word document and the
mimeType String is "application/octet-stream" instead of the expected
"application/msword".
However, uploading Excel spreadsheets and PDF files provided the
expected results of "application/vnd.ms-excel" and "application/pdf".
(see http://www.bc.edu/bc_org/tvp/email/helpers.shtml or
http://www.yolinux.com/TUTORIALS/LinuxTutorialMimeTypesAndApplications.html
for lists of mime types)
So, does anybody know why the Microsoft Word documents send the wrong
mime type ? Should I instead just use the file extension to determine
file type perhaps ?
Thanks in advance,

Otherwise the JDialog is very very wide when the text is long.
How can I do that?

- Static class - one per JVM or one per app?I have a class called MyClass that contains a static variable (myVar).
I have two J2EE apps running on WebSphere under the same JVM,
MyFirstApp and MySecondApp. From MyFirstApp i set the value of myVar by
doing MyClass.setMyVar(3).
....what will be the value of MyClass.getMyVar() when run from
MySecondApp?
ie - will the static var have scope across the whole JVM or just the
web app?
Thanks

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.

- 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?

You can't - that's the source of the problem and where

- 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,

- array initilization and memory usageI'm a little new here, so please bear with me if this sounds like a
goofy
question!...
let's say that I have an class with 15 or so members, each taking up a
fair
amount of space - we'll call this class bars
If I create an array of 400 empty bars objects, but only instantiate
the
first five or so then am I still setting aside the memory for the other
395?
I hope that made sense!
Thanks

- Memory issueHi All,
I have a problem with memory when I use a connection to a database. I have
also posted the question in the database group but as I suspect that it has
to do with garbage collection I also post the question here.
I have a problem with memory using SQLserver on a server running WIN2K
Advanced Server with 2 GB! of internal memory. We limmited the SQLserver
memory to 1 GB and 512 MB for JVM (version 1.4.2_01). The OutOfMemory error
is always at the same place in the jdbc driver as shown below.
java.lang.OutOfMemoryError
at com.microsoft.util.UtilPagedTempBuffer.compressBlockList(Unknown Source)
at com.microsoft.util.UtilPagedTempBuffer.getBlock(Unknown Source)
at com.microsoft.util.UtilPagedTempBuffer.write(Unknown Source)
at com.microsoft.util.UtilPagedTempBuffer.write(Unknown Source)
at com.microsoft.util.UtilByteArrayDataProvider.receive(Unknown Source)
at com.microsoft.util.UtilByteOrderedDataReader.receive(Unknown Source)
at com.microsoft.jdbc.sqlserver.tds.TDSRPCRequest.submitRequest(Unknown
Source)
at com.microsoft.jdbc.sqlserver.tds.TDSCursorRequest.openCursor(Unknown
Source)
at com.microsoft.jdbc.sqlserver.SQLServerImplStatement.execute(Unknown
Source)
at com.microsoft.jdbc.base.BaseStatement.commonExecute(Unknown Source)
at com.microsoft.jdbc.base.BaseStatement.executeQueryInternal(Unknown
Source)
at com.microsoft.jdbc.base.BasePreparedStatement.executeQuery(Unknown
Source)
.............................................. Truncated from here
.................................................
If I run (using same database & JVM) on a computer (W2K prof.) with 512 MB
internal memory and no limmit set for MS-Sqlserver but for JVM 128 MB doing
the same stuff, there is no problem at all.
I suspect it has something to do with a late "kicking in" of the Garbage
Collection causing memory segmentation. So when a big chunk of memory is
required (a large result-set from the database) no contigouis memory block
of memory is availble in the current heap. The JVM claims more memory to
expand the heap, grows and grows until it cosses the limmit. But I also
tought that garbage collection takes care of that too.
I hope some one has seen this behaviour and can point me in the right
direction.
TIA.
Frank.

- Waiting For A Synchronized MethodSay thread1 begins executing a synchronized method.
While it's executing, both thread2 and thread3 call the synchronized
method, in that order.
When thread1 ends executing and gives up its lock, is thread2
guaranteed to execute next (because it's been waiting longer than
thread3), or is it possible that thread3 executes first?
My experiments seem to point to thread2 always running first in the
above situation, but I'd like to verify this.
Thanks,
John

java-programmer, 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....

Hell yeah Bill J! Just try Blue J: http://edu.netbeans.org/bluej/
It's like NetBeans but without the girth. This was developed
originally by university professors and students and is geared for
those learning java. Give it a try. ;)

I can't tell from briefly glancing at your headers if you use windows or
not.
If you do I suggest GEL - it is the most no frills GUI environment (just be
sure to turn off smart tabs cause they don't work)
Sometimes it crashes - so I guess it is not perfect, but for small learner
projects where you don't want code that you don't understand being
autogenerated and/or hidden - it is the best out there.
I have historically used Netbeans to make my dialogs, and then used GEL to
implement my project. Really though, once you get the basics down (after
about 60 hours of coding) you will want to make GUI apps and the integrated
environments can't be beat. I actually like NetBeans when I have a
"project" but when I have a single class/single file (usually console
based) I use GEL all the time.
On the other hand using the console and notepad or VI with a couple nice
batch files is not a bad learning tool.

It might be better to stick with what the class is using, you'll be able
to get more help from the prof and fellow students.
Try this quick start guide:
http://www.netbeans.org/kb/50/quickstart.html
Then see if this tutorial is useful:
http://www.netbeans.org/kb/50/using-netbeans/index.html
There are more like that here:

As long as it's not Eclipse, it can't be all bad. ^_^ I've never tried
this, I might check it out tho.

Yes Bill, what Mark and Luc said is very good. I use GEL for quick stuff
but now a days have been hanging around Eclipse for Java and PHP.
Netbeans BlueJ Edition is nice if migrating up to the big boys toys
lol... You may want to look at Just BlueJ. Since you are learning the
language this may be the better approach. It will help you learn Java
with a OOP and OOD orientation.

Many thanks. I did try BlueJ, but it wasn't much better than NetBeans.
It just didn't make sense to me. I'm sure if I invested a little time
to read the docs it would, and I like the idea of taking a step towards
netbeans, but I just didn't have time and in fact submitted my
assignments late, 50% off.
After an hour I gave up and tried jGRASP. It was immediately
intuitively familiar, from other IDEs, and I got the programs written
pronto. So I'll stick with it until such time as I have time to check
into BlueJ a bit more.
Thanks much...

You are right, JGRASP is more intuitive. I normally do recommend JGRASP
but was caught up on the Netbeans thing. They are both from academia
so you can't go wrong. JGRASP has the older IDE feel from days gone by...

Dudes.........
you are missing the point!!! netbeans is no way considered
to be user friendly. JCreator is an excellent editor for
beginners.........(but its windows based :( ) . Anyway Eclipse is the
best of the best of the best . you cant beat this IDE . really once you
get to know what is a workspace and what is a package.........you are
on cloud 9 with eclipse....Besides it looks so much better on linux
than netbeans !!!
either go for JCreator or eclipse .Dont bother yourself with netbeans.
Netbeans (i use it for just the matissa thing which rocks! )

avoid these netbeans stereo types....... as a beginner you are better
off with eclipse....netbeans has so many bugs (null pointer exception ,
overflow exception ) to name a few . !

A very nice GUI editor (aka "form" designer) for particular tasks, which
is part of NetBeans.
May I provide some general suggestions? Instead of listening to the
fanboys ("the best of the best" ha, ha, ha)
a) you accept the fact the there is no such thing as "the best" tool,
IDE, computer language, etc.
b) many depends on individual preferences, the task at hand, experience,
education, requirements, etc. And, yes, even it seems many depends on
the mental health and sanity of the user
c) Which, as a consequence, means you, and only you can decide what is
"the best" in your particular circumstances, with your particular
background.
d) In other words: Try them. Try them all, or at least try as much as
you can get your hands on
e) Select at least two you like best and use them. Two, or more, so you
don't get dependent on a certain IDE. So you aren't helpless, don't look
stupid, and don't have to whine should you have to work in an
environment where your "best" tool is not available. So you can look
beyond your own nose and don't have to utter nonsense like "the best of
the best oft the ..."
f) Learn to use the command line tools, too. For the same reason as
above. In fact, I in general suggest to first master the command line
tools and all the basics around them before starting with an IDE.

Power? Another meaningless term in this discussion. It depends on what
you need.

You are aware that many people here don't like to be called "dude"?

Each and every word of yours is right.............. I
agree totally . As you said beginners should first know how to use the
command line options before going for IDE. this is the suggested to the
person who started this topic . do try out the command line option and
then switch over.......... As you say , it avoids people from getting
dependent on IDEs when they are not available .The command line is
always there for you!

- 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

- 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?

- 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.

- 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.
Alden

- WebSphere 4.0 and VisibrokerI 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!

- 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

- 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

- Failover pattern
2 or more hosts, each running the same application.
Each Java application on each host is assigned a specific task.
Say:
App on host1 does task X
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 ?
