If you honestly believe that posting a subject as "urgent" is rude then you
seriously have not been in newsgroup long enough to realise that it is
common practice. Whether you respond to a urgent posting is your perogative,
but making absurd comments is simply a reflection of your stupidity. That
said, continuing to respond to this thread will only prove me right.

- JAI rotate problem (change of brightness)hi!
I'm developing small image processing software, I would like to rotate a
grayscale image.
I have a delcaration of the image inside class CMyImage:
public BufferedImage workImage;
int width, height;
Having source code:
public void process(CMyImage image, int angle)
{
float radiansAngle = (float)Math.toRadians(angle);
// rotation center
float centerX = (float)image.width / 2;
float centerY = (float)image.height / 2;
ParameterBlock pb = new ParameterBlock();
pb.addSource(image.workImage);
pb.add(centerX);
pb.add(centerY);
pb.add(radiansAngle);
pb.add(new javax.media.jai.InterpolationBicubic(10));
// create a new, rotated image
PlanarImage rotatedImage = JAI.create("rotate", pb);
// display the rotated image
...
}
image is rotated, I can see the result but... it has changed brightness!
when I rotate 0', 90', 180' or 360' - this problem doesn't occur, image
has the same intensity, but for other angles, like 1' image is just more
bright, histogram also shows this change.
what do you think about this problem? I'm not sure how rotation in JAI
is implemented - maybe this is just some problem of the ATI Radeon
driver? my system: WindowsXP, Eclipse 3.2... I can provide images if
it's required. Waiting for your help!

- vim, java and javadocVim using java coders:
Has anyone made, or know of, a way to use Vim's lookup feature with the
javadoc system? I like how when I'm editing a C file I can put my cursor on a
function and hit K to bring up a man page! I figured out how to fine-tune
this feature and made it work for Perl functions.
I would love to be able to put my cursor on, say, "String" and have vim jump
to lang/String.html in the html documentation, or something similar. If it
isn't already done then I may want to do this myself.
Thanks!

- upgrade Axis 1 to 2Hello,
I have running an Axis1-Webservice, which is used by some clients. Now I
want migrate to Axis2. The clients shall run further without any
modifications.
Is this generaly possible?
I made some experiments and got the following problem:
The old Axis 1 - WSDL contains the following lines. (here the code without
types, namespaces, etc.)
<types>
<schema>
<complexType name="MyParam">
<sequence>
<element name="paramDetail_1" />
<element name="paramDetail_2" />
</sequence>
</complexType>
<complexType name="MyReturn">
<sequence>
<element name="returnDetail_1" />
<element name="returnDetail_2" />
<element name="request" type="MyParam" />
</sequence>
</complexType>
<element name="MyFunctionParam" type="MyParam" />
<element name="MyFunctionReturn" type="MyReturn" />
</schema>
</types>
<message name="MyFunctionParamMsg">
<part element="MyFunctionParam" name="MyFunctionParam" />
</message>
<message name="MyFunctionReturnMsg">
<part element="MyFunctionReturn" name="MyFunctionReturn" />
</message>
With Axis 1 the following code for the "main"-function is gerenated by
java2wsdl:
MyParam myFunction(MyParam param0) {...}
With Axis 2 the following code is generated:
MyFunctionReturn myFunction(MyFunctionParam param0) {...}
With Axis 1 the name of the complexType> is used, with Axis 2the name of the
<element>.
Now I modified the WSDL for Axis 2:
<types>
<schema>
<element name="MyParam">
<complexType>
<sequence>
<element name="paramDetail_1" />
<element name="paramDetail_2" />
</sequence>
</complexType>
</element>
<element name="MyReturn">
<complexType>
<sequence>
<element name="returnDetail_1" />
<element name="returnDetail_2" />
<element name="request" type="MyParam" />
</sequence>
</complexType>
</element>
<element name="MyFunctionParam" type="MyParam" />
<element name="MyFunctionReturn" type="MyReturn" />
</schema>
</types>
<message name="MyFunctionParamMsg">
<part element="MyParam" name="parameters" />
</message>
<message name="MyFunctionReturnMsg">
<part element="MyReturn" name="returnType" />
</message>
without the line
<element name="request" type="MyParam" />
wsdl2java creates the equal signature for the "main"-function like Axis1.
But when the wsdl contains this line above, there are exceptions.
The problem is, that at Axis 1 MyParam is a <complexType>
and at Axis 2 an <element>
Has somebody any idea, what I can do?

- Can a java program know what kind of server it is running on?Is there a pure java way to find the identity of the web server that
the application is running on?
A system property? A JMX query? Anything?
I want to have my webapp behave differently based on the webserver
being used. Is there a way to tell what the server is (tomcat,
websphere, weblogic, etc)?

- Azureus ... forced to use Windows Version ...
The other day, I posted about download issues with Azureus ... today,
figuring to see if it was my network, or FreeBSD, I installed it on one of
my Windows boxes, and am currently downloading at ~85kb/s ;(
Please note that this Windows box is sitting *behind* the same FreeBSD box
that I'm lucky to get 1kb/s on ... the FreeBSD is the router ...
I don't know if this is a java issue, or freebsd issue ... but I really
don't have any ideas on how to debug why ...
Other then the machine its running on, I have Azureus setup the same,
including using java 1.5.0 ... but, of course, the version on the FreeBSD
is the new diablo binary ...
thoughts?

- Pls advice: Best OpenSource Java Framework/Portal for this requirements?Hi all,
I'm looking at different frameworks like JBoss Portal, GridSphere,
etc. but some opinion of any of you who has an experience with
frameworks would be helpful.
The most important requirement for the final system that will be
built on the framework is an easy way that the end-user can create his
own 'sub-portal' with predefined pages and an access to the predefined
'components' he can embed on those 'sub-portal' pages. Both - pages
(i.e. home, guestbook, history) and 'components' are predefined by the
system (portal, framework) but the user can fully customize their look
and feel even by replacing the default HTML code with his own.
The idea is similar to the way the blog platforms work: you can create
your own blog, once you do it, you get a list of predefined pages like
main, new comment, guest book, archive, etc.
The important thing is that you can completely change the HTML code of
those predefined pages within your blog.
You also get a set of 'components' or 'tags' like {blog}, {nick},
{guestbook}, etc. and you may embed them in your predefined pages
using HTML - as you wish. The content provided by these 'components'
is of course predefined by the blog platform so you can change only
look and feel of them.
So - which of the available opensource java-based frameworks/portals
could be the best to implement the functionality described above?
Thanks in advance for your opinions,
Tomasz

- fixing image sizeI realise there have been several posting on this subject already.
However, despite these, I still can't quite work out how to do this.
I need to take the image from a file (.gif .jpg etc), ensure that the
entire image fits on a JPanel of some size, then put this JPanel onto
another Jpanel.
From what I could gather, it looked like I had to extend JPanel and
override paint(). The problem comes when I try to use drawImage().
Here's the code.
//relevent imports
public class Picture extends JPanel
{
private String fileName;
/** Creates a new instance of Picture */
public Picture(String file)
{
fileName=file;
}
public void paint(Graphics g)
{
super.paintComponent(g);
}
}

- J2EE architecture questionHello.
Iv read a spec from a firm which wants to build a J2EE application,
but the application is not supposed to be web based. The reason for
this is mostly a very complex UI.
From what ive read about the J2EE architecture ,the presentation layer
has always been servlets or jsp.
Is it a posibility / option to build a J2EE application without the
web based presentation layer?

> to flush after every write.
There is nothing in the Javadocs to indicate that System.err is unbuffered.
Like System.out, System.err is a java.io.PrintStream. The docs for
PrintStream imply that instances are buffered, else the flush() method would
be meaningless. So it is not accurate, or at least not safe to say that
System.err is unbuffered.
That leaves auto-flushing. Nothing in the Javadocs for System.err indicates
that it's created with autoFlush on. Did you check the source for your
particular flavor of Java to see if it is?
In my installation, the source shows:
setErr0(new PrintStream(new BufferedOutputStream(fdErr, 128), true));
Whaddaya know? System.err is buffered in my installation.
Sun Java JDK 1.6.0_10b25, 64 bit, Linux.
Are you quite certain that System.err is unbuffered in your Java installation?

- File creation in the web applications' rootHello all.
Is it possible to get the path at which my application root is placed
by means of either the ServletContext or the ServletConfig object?
What I am trying to do here is to dynamically create a Javascript file
on the fly and put in the script directory of my web application. But
since the working directory in a web applications case is the
directory which contains the app servers' executable, any new file
created would be created there and I don't want to hard code the path
to my script folder. I want everything to be relative to the
applications' root as far as possible.
Can it be done without any special configuration, the way I can get a
resource present in the application root by the getResource() method?
Any kind of help would be greatly appreciated.
Regards,
sasuke.

- Connection's Close method, should it be called?Hi,
I am unsure whether it is good Java practise to use Close() to close a
database Connection.
EG:
dbConnection = DriverManager.getConnection(url, user, pass);
Statement sqlStatement = dbConnection.createStatement...
String sql = "SELECT ...
ResultSet results = sqlStatement.executeQuery(sql);
...do stuff with results...
Now that I've finished should I call close() or not?
dbConnection.close();
The API documentation makes it clear it will be closed automatically when
the garbage is collected -- but is it good practise to close it 'manually'
when you've finished with it?
Thanks,
MS
API Doc:
void close()
throws SQLException
Releases this Connection object's database and JDBC resources immediately
instead of waiting for them to be automatically released.
Calling the method close on a Connection object that is already closed is
a no-op.
Note: A Connection object is automatically closed when it is garbage
collected. Certain fatal errors also close a Connection object.
Throws: SQLException - if a database access error occurs

- LISTEN UP EVERYBODY. put your programming skills to use in this new MMORPG game. details listedRun Online is a new MMORPG( massive multiplayer online role playing
game) in progress. I wish for it to be devoloped completley in java,
making it platform independent( able to run on any platform). The game
is set in medivial time(not finalized yet). When i firsted dreamed up
this project i had a huge case of amatures syndrome, as in the game was
so magnificently filled with a 1000nd classes, over a million monsters,
billions of monsters, and large world(I even had planned on putting in
25 other outer space planets)!!!!!! and all of these looked realistic.
Yep, thats the amatures syndrome. I got over it slowly as i realized
the difficulty in creating even the smallest of worlds. I couldnt
possibly even do that on my own, so i desided to put togheter this
dream team of specilists.
1 Project Manager: The project managers job is to over look the project
and organize the events and keep the project rolling.
.
Meeee!!!!
5 java programmers: the game is created completley in java. Im not sure
that 5 people is even enough, but that should do for now. Their job is
to program different segments of the game( each can focus on a
different aspect of the game to program)
.
.
.
.
.
3 graphic designers/ animation experts with basic knowledge of java:
their job is to create teh textures, buildings, and animations of the
world and the character as well as all the items and monsters.
.
.
1 database expert: manages the database part of the job.He/She must
make 100ds of reliable databases for usename, passwords. Items of a
character. Skills and many more. Its a key part of the game to get this
right.
.
1 Network administrator, security monitor: Must create an simple
encryption to code the graphics send over by the graphic people as
well as text written in the forum. This will prevent those outside of
"The Team" from getting into the game files and misusing it. The
network administrator part requires for knowledge in that field. This
person will the one responsible for having the game work smoothly on
the web, and sequerly.
.
3 Researchers/ advertisers: The reserchers must reserch and find
suitable programs, and information relating to the game of aspects of
the game. The advertisers will be responsible for advertising the game
to the public once it's finished. They will have to create cool
banners, and catchy phraces to help make drive the traffic to the game.
.
.
.
2 web designers: The web designers will design the website in which the
game will be hosted. The website must be trendy as well as easy to
navigate and quickly loadable.
.
.
2 Gamers/test players: They test out the game, find bugs, give
suggestions. They will be among the first in line to get a moderator
role.
.
.
If you would like to know more about any of these, or wish to join The
Project Team, plz email me at email***@***.com with your
qualifications and comments. You definetly have a good chance of
getting into the project if you sign up early. I will personaly read
all the applications and put my sincear thoughts into it.
Youc can also view the forum at http://runonline.aceboard.com
( it has no topics at the moment)

- Eclipse path problem while opening file.When ever I try to read/open '.properties' (for that matter any file)
inside my project(for example I try to open system.properties file in
HelloWorld class) it cannot open/find it.
For example if I have a project called project1 which has java source
files in
src folder then and in any of the class files I cant open any of the
files inside the
src folder. No matter where I place the file that has to be read
(inside project1 or src
or build folder) it simply gives me java.io.FileNotFoundException
Instead if I give the complete path it works. How can I read the files
relative to
my project folder without giving the complete path?
It seems that when I run my application in looks in ECLIPSE_HOME/bin
folder, for the
file being read, which of course I don't want to happen.
I am using Eclipse 3.2 (WTP), Windows XP SP2 JDK 1.5.03
Any pointers how to fix this?
