- Web Services without SOAPCan someone point me in the right direction? I am new to Java
(somewhat) but have built many web services in .Net. This time
however, I need to build one in Java without SOAP. I am using eclipse
and have Tomcat and Axis running. Is there a book .... tutorial ...
concept to tearing web services away from the fat envelopes of SOAP. I
need something light and quick. What are my options?
TIA

- Understanding some Java basicsHi experts,
I'm a bit familiar to Java and i want to begin programming under Java
with a good beginner's resource but there are some confusions in my
mind:
1-I know Java applications cannot be run as an executable file, there
must be a interpreter needed, what's the most convenient way to run
and show my projects under computer enviroment? Applet-like class
files inside browsers or mobile emulators? Or JAR archives?
2-I want to learn basics for developing applications for mobile
phones(like modern Nokia phones) and i learnt that there are some
concepts like MIDP, MIDLETs, J2ME (micro edition) and like that. What
concept is the complete and the most convenient standard for beginning
development for mobile phones?
3-.Which IDE is the most easy-to-understand? I heard about Netbeans
with no experience, also i'm familiar to Microsoft's Visual Studio
but don't know if there's VS-like IDEs for Java which also supports
development for mobile area.
4-I have the latest Java run-time installed(Java Standard Edition from
www.java.com), then i need to download Java Development Kit (JDK) to
start programming under JAVA. Right?
As Final:
5- I heard inspirations for Java about being similiar to C++ and low-
level languages. So, how good is to transfer and manipulate C++
syntaxes into Java programming enviroment?
I needed to consult to your big experiences to have a good start with
Java :-) If you help me to understand and recommend the goods, i'd
appreciate.

- Stop logging to catalina.out?Hi
I am using Tomcat 5.5.9 with Log4J. I want to stop using catalina.out
as logging output and only use log4j files instead. However, no matter
what I do Tomcat keeps appending log4j outputs to catalina.out.
According to Tomcat documentation, only System.out and System.err
output goes there. I set up my log4j logging according to this
document:
http://tomcat.apache.org/tomcat-5.5-doc/logging.html
Any help would be greatly appreciated. Thanks.

- Can't locate JavaxHi,
I am using DrJava, and I am writing a program that has the following
statement:
import javax.swing;
It gives me this error when compiled:
File: C:\Program Files\DrJava\CustomJFrame.java [line: 1]
Error: package javax does not exist
I did set my classpath variable to:
c:\j2sdk1.4.2\lib\tools.jar;C:\j2sdk1.4.2_01\src\javax
where C:\j2sdk1.4.2_01\src\javax is where javax is located.
What am I doing wrong?

- tungsten screen sizeHi! This is my first program written for the Tungsten E, which has a
320x320 screen. It prints out 160x144, which is a quarter of actual
with extra space around, and the lines drawn are two pixels wide. Is
there a way to get it to fix this?
package hello;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
public class Hello extends MIDlet {
private Canvas canvas;
public Hello() {
canvas = new Canvas() {
public void paint(Graphics g) {
g.setColor(0);
g.fillRect(0,0,getWidth(),getHeight());
g.setColor(0xffffff);
g.drawString("Pfui! "+getWidth()+"x"+getHeight(), //print size
0,0,Graphics.TOP|Graphics.LEFT);
for(int i = 10; i < getHeight(); i += 10)
g.drawLine(0,i,getWidth(),i); //draw lines
}
public void pointerPressed(int x,int y) {
Hello.this.notifyDestroyed(); //exit
program
}
public void keyPressed(int keyCode) {
Hello.this.notifyDestroyed();
}
};
}
public void startApp() {
Display.getDisplay(this).setCurrent(canvas);
}
public void pauseApp() {
}
public void destroyApp(boolean unc) {
}
}

- Web service : JAX-RPC handler and loggingHello,
I want to log every call to my web services (the logging message must
group the SOAP message and some additional context information). I
will log the request and the response.
Log messaging must be assured by a MQ infrastructure.
I was going to implement the logging with a JAX-RPC handler using JMS.
But the J2EE for Web services spec indicate that :
Handlers run under the transaction context of the component they are
associated to.
So, if I associate my handler with an EJB Session stateless and this
latter one calls setRollbackOnly, my logging actions will also be
rolled back.
Is there a good solution ?
Thanks for your help

- Willing to "Barrow"I don't want to learn Java, but... I'd like to build an AWT-based applet
that takes text input from a user-supplied box (text box) and, if the text
matches my secret phrase, pass the user into my web site. (I know this
isn't perfect security, but it's fine by me.)
Does anyone know where I can get some Java source that is close to
functionality? It's rather barrow this sample source than read a "Teach
Yourself Java in 21 Days" book...
Thanks!

- Associating HashMap values with items in a ListHi, I am iterating through a text file(property file) and storing the
section headers as items in a List. I want to associate specific
property value pairs( that I plan to put in a HashMap) with each
section header in my List, i guess you waould say its kinda of like a
parent child realtionship. I am looking for some guidance in the right
direction on how to properly do this or is this not the way I should be
thinking of the solution? Please let me know? :)

Not at all true. This is the largest difference between the professional
software engineer and the amateur programmer. The amateur tries to optimize
everything. The professional measures first, and optimizes only where it's
worthwhile, and measures again to ensure that the "optimization" actually
helps. When I hear a suggestion to change one of the most widely used
protocols in the world, and consider how many person-hours the
standardization process would consume, the amount of HTTP-processing code
that would have to change, the opportunity for introducing bugs into
currently correct HTTP implementations, the indefinitely prolonged need for
backward compatibility, the expense involved in negotiating the version of
HTTP used in any given conversation, etc, and I don't see even an estimate
of how much useful bandwidth would actually be saved, much less an actual
measurement, it's clearly amateur hour.

- modifying java.lang.String.javaHi,
I'm trying to modify java.lang.String.java and add the modified
String.class to
rt.jar [THIS IS FOR MYSELF ONLY AND WILL NOT BE DEPLOYED].
I cannot add "private final boolean tainted[] = new
boolean[5];" to String.java. If I do, it still compiles and I can add
it to rt.jar and compile a test program against it. However, the JVM
crashes with a strange message:
java.lang.IllegalArgumentException: name can't be empty
at java.security.BasicPermission.init(Unknown Source)
at java.security.BasicPermission.<init>(Unknown Source)
at java.lang.RuntimePermission.<init>(Unknown Source)
at java.lang.Thread.<clinit>(Unknown Source)
I tried various ways of rewriting the above such as adding "private
final boolean tainted[];" and initializing it in each constructor.
Nothing works.
I can add methods to String.java and even the member variable "private
boolean isTainted;" and it works just fine. Do you have any ideas for
why adding a boolean array does not work (or better yet how to get
around this issue)?
Thank you,
Daniel

- Distributed approaches in JavaHi everybody,
I'd like to know your opinion about the current trends and
state-of-the-art of distributed technologies using Java: what is
currently used, why, which technologies are obsolete, etc. from RMI,
CORBA, JavaSpaces/JINI, etc. A reference were the advantages and
disadvantages of each of the approaches would also be great.
Thanks in advance,

java-programmer, loading a resource from a jar file
Hi All,
When I generate the jar file from the command line, loading a resource
e.g. text file or gif works fine but when I "export" the jar file from
within eclipse (or using ant), the loading does not work. What is the
difference? And how can I fix this problem?
Thanks in advance,

Put a '.' in column 21 of the glixleblot file.
If that does not work, try describing a
reproducible problem.

It is a reproducible problem!
getClass().getClassLoader().getResourceAsStream() does not work when I
export the jar from within eclipse but it works fine when I generate the
jar from the command line.

- Java String.replaceAll() not behaving as expectedGiven a string "s", I'd like to convert all the line separators into
their "escaped" string equivalents. i.e. a dos/windows newline gets
converted into the literal string "\r\n".
I tried this in my java code...
s = s.replaceAll("\n", "\\n");
s = s.replaceAll("\r", "\\r");
but I end up with "rn" instead of "\r\n"
I assume the problem has something to do with the regex pattern
replacement but it seems like it should work.
What am I doing wrong?

- J2ME - Newbie questionHi NG,
after I've googled now for several hours, I'm more confused then
before. And I thought, what I want to do is a simple every-day
problem.
I want to write an application, that communicates with a palm device,
in this case the m500. Therefore, I neet the following features:
* write/create files from within the palm device to the memory of the
palm
* read this files from within my desktop application.
Most important in my case would be files in xml format. I think this
is a problem many programmers must find when they want to develop
applications that use a palm device. But it seems that there is
nowhere a useful example. If anybody has developped similar things, or
can give me any hint or url, would be a great help.
What I did already: I installed the WTK2.0, build some examples, tried
to install the PDADemo example on my palm and execute it. I get the
error:
can't load javax.microedition.io.file.FileConnector
I think that would be exactly the thing I would need, but it seems not
to work.
Thanks very much in advance for every kind of help,
Bene

In a a stateful session bean I'm looking up a data source that wraps a
connection pool and using it to retrieve a connection.
How do I return the connection to the pool when I'm done? Is conn.close()
the right thing to do here?
If I just let it go out of scope I eventually get an exception in the pool
with an "out of resources" error.

- Difficulty resizing window inside an AppletHi all,
I have a Java puzzle written as an applet that I've been working on. So far
I've never been able to figure out how to resize it from inside the applet
itself.
So I created a very elaborate HTML file, where I use JavaScript which:
1. queries the screen resolution and browser,
2. dynamically opens a window based on the values returned from (1),
3. dynamically writes the applet/object tag to that window also based on
(1).
I'd love to get rid of this complicated mess of html/js code and do it from
pure Java if I can. For one thing, having two page refreshes is slow for the
user. I've tried setSize() and setBounds from every component level I can
think of. There are never any errors but it never works either. I noticed
that resize() works from inside a JDialog, but not from JPanel. I'd be happy
to use a JDialog to hold the JPEG image, instead of JPanel, but that doesn't
seem to work.
Also, I'd love to be able to resize on the fly. Is it a big deal to trap the
window/resize event to allow the user to set the size?
I'd greatly appreciate any thoughts or ideas you may have.
Best regards,
Dave
