- javax.mail truncated urlHi!
I use javax.mail to send http mails that include urls. On some mail
clients, including Lotus iNotes, urls contained in the mail are
truncated. For example:
http://www.crappysite.com/index.html?param1=foo¶m2=bar
becomes
http://www.crappysite.com/index.html?param1
Encoding in the email is set to "quoted-printable". I tried to set it
to "base64" but it didn't resolve the problem.
Thanks!

- HTTP creepIf you look at the packet headers going back and forth to your HTTP
server, you will discover a HECK of a lot of blather that really is
not doing much.
It is made worse by it all being human readable without abbreviations.
Add this overhead up on all packet headers being transferred each day
and you see a stupendous waste of bandwidth.
HTTP should be put on a diet, with rigid defaults, bitfield headers,
and compressed messages.
The original protocol was designed for maximum flexibility. Now we
have some experience, we can tighten it up.
It matters now that you have tiny handhelds trying to surf the net
over limited bandwidth.

- Together J 5.5Hi,
once there was a "community version" of TogetherJ. I have a 5.5 on CD
from a Together Presentation long ago but I am missing the community
"licence.tg". It was free (long time ago) but no longer available now.
Anybody out there with one of theses files?
Thx,

- evaluating the computers TCP and UDP socket statesI am looking to be able to read the TCP and UDP socket states of the
computer using Java2.
I want to be able to determine when a certain TCP socket is listening
vs. connected, etc.
Does the java2 API cover this sort of ability?
thanks,
Dave Haga
p.s. just to be clear, I want to understand the state of ALL sockets,
not just the ones opened by Java. for instance, "netstat -a" on a
windows platform provides the status of all TCP and UDP sockets.

- SendMailServlet example & server setup ?I tried this example :
// import the JavaMail packages
import javax.mail.*;
import javax.mail.internet.*;
// import the servlet packages
import javax.servlet.*;
import javax.servlet.http.*;
// import misc classes that we need
import java.util.*;
import java.io.*;
public class SendMailServlet extends HttpServlet {
String smtpServer;
public void init(ServletConfig config) throws ServletException
{
super.init(config);
// get the SMTP server from the servlet properties
smtpServer = config.getInitParameter("smtpServer");
}
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
// get the message parameters from the HTML page
String from = req.getParameter("from");
String to = req.getParameter("to");
String subject = req.getParameter("subject");
String text = req.getParameter("text");
PrintWriter out = res.getWriter();
res.setContentType("text/html");
try {
// set the SMTP host property value
Properties properties = System.getProperties();
properties.put("smtp.mail.yahoo.com", smtpServer);
// create a JavaMail session
Session session = Session.getInstance(properties, null);
// create a new MIME message
MimeMessage message = new MimeMessage(session);
// set the from address
Address fromAddress = new InternetAddress(from);
message.setFrom(fromAddress);
// set the to address
if (to != null) {
Address[] toAddress = InternetAddress.parse(to);
message.setRecipients(Message.RecipientType.TO, toAddress);
}
else
throw new MessagingException("No \"To\" address specified");
// set the subject
message.setSubject(subject);
// set the message body
message.setText(text);
// send the message
Transport.send(message);
out.println("Message sent successfully.");
}
catch (AddressException e) {
out.println("Invalid e-mail address.<br>" + e.getMessage());
}
catch (SendFailedException e) {
out.println("Send failed.<br>" + e.getMessage());
}
catch (MessagingException e) {
out.println("Unexpected error.<br>" + e.getMessage());
}
}
}
and got this:

- Basic Struts loggingI'm learning Struts and I've got a simple example app running. I wanted
to get logging working, so in the perform() method of my Action I put
the code:
ActionServlet as = getServlet();
as.log("hello world");
This compiled with no errors and ran without any problem; but the string
was not written to either of the log files catalina.out or
localhost_log.2004-09-21.txt (this is on Tomcat).
Any hints or clues about how to get simple logging working? I looked at
log4j and commons-logging but I want to start simpler.

- java script problems XP dpreview and other sitesMainly on the popular digital photo site dpreview.com but
unfortunately not restricted to this site I sooner or later run into
the problem that the site navigation and posting does not work any
more: Normally a list of available sub items is displayed on the left
side, when positioning the cursor on any a specific pull down pops up.
But every other week or so the site is displayed with an empty
background where the menu normaly is and therefore no further
navigation ist possible. I Opera I get the menus but when I click the
javascript enabled send button for posts nothing happens too.
I am running Windos XP Home with all current updates with Norton
Internet Security 2002 and Norton System Works 2002. Even after a
clean reinstall of all apps with all updates I don't get a stable
system. My only rescue so far is to load a system partion image of a
good status some weeks ago. But as I said, this does not last for
long.
I tried reinstalling Windows Script 5.6, but it did not help.

- jdbc commit issueHi,
I'm facing some problems with the JDBC connection commit.
I'm using an Oracle8i client and server.
The jdbc library is classes12.jar
My application uses eclipse3.1 as an IDE and the jdk version is
jdk1.5.0_01
The flow of logic is such that I acquire 2 to 3 connections to my
database repository. On each of these connections some update/insert
statements
are executed (through jdbc PrepareStatement->executeUpdate())
After the update statements I issue a connection.commit() on each of
the connections where update statements are fired.
I have noticed sometimes that although connection.commit has been
issued, my DB does not have any data.
If anyone has any clue to this please let me know.
Thanks for your time.

- 360degree rotation in Java2DI have a bit of a problem rotating Shapes using the Graphics2D function
rotate(theta).
My high-school trig lessons indeed tell me that sine and cosine functions go
between -90 degrees and +90 degrees (or 0 and 180, if you like), and I can
see why this means that when I call the rotate(...) function, it will not
rotate the object all the way round the whole 360 degrees.
Currently, I have a duplicate Shape object which is flipped so that for one
half of the rotation the original shape is drawn, and for the second half,
the other...
There must be a better way!
Any ideas?
Cheers :o)

- awt default toolkitThe following will not show the image nor will it throw any exceptions. Not
throwing exceptions doesn't surprise me because the documentation show that
it won't. That is a little surprising in itself. I am not using Swing
components.
public void paint(Graphics g){
String fileName = "dir/a.gif";
Toolkit toolkit = Toolkit.getDefaultToolkit();
Image img = toolkit.getImage(fileName);
// an awt panel's Graphics context doesnot show the image
g.drawImage(img, 0,0, null);
//this works fine
g.drawString("aString",50,50);
}

- Using wildcard character in web.xml in Tomcat 5I am trying to achieve the following:
<url-pattern>/a*</urlpattern> then go into servlet A. This would
include /a, /aa, /abc/123 etc.
I notice that servlet 2.4 doesn't treat * as a wildcard character in
this case. Therefore, servlet A would only be called if the URL is
exactly /a*.
I need to create this pattern for all characters and numbers except
when the path starts with '/_'. Therefore, I can not use a '/*'
notation. Can anyone suggest a workaround to this issue?
Thanks,
TC

java-programmer >> [Static Classes]
it's pretty simple
static class methods or fields mean that the code modified by the keyword
can be used without having to instanciate the class.
is it ok?
write back if you have any others questions

- Tomcat4: Default Page Encoding UTF8Hi,
I am using Tomcat 4.1.27 running servlets which worked
perfectly under Tomcat 3. The problem is: (unfortunately)
the special characters (like german umlaute) are not
html encoded. Under tomcat 3 this was no problem, but with
the new tomcat the page-encoding is wrong. When I manually
change the page encoding in the browser to utf-8 everything
is OK. I could now go through all servlets and change the
content-type to charset utf-8, but I try to avoid this.
(as there where not written by me).
Is there any possiblilty the change the default page encoding
to utf-8? (like in the server.xml or so)
Thank you for any help!!!

- CLASSPATH?WinXP Pro, JRE 1.4.2_03
I've just discovered that according to my Environment Variables section of
the System icon (Control Panel), I don't have a CLASSPATH variable. I used
SET from a command prompt to confirm that this is the case. No such
variable. So how come I can run basic (UI) Java programs OK? Shouldn't
CLASSPATH be pointing to the jar file containing these basic classes I'm
using? The problem is, JMF installation instructions seem to say I should
add the path to the jar file to CLASSPATH, but how can I if I have no such
variable? {:v)
Am I missing something?

- JTextArea SizeHello, I'm writing a java app for a pda and as the screen size is tiny I
want to write a MiniDialog class. I only want a JTextArea and an OK button
on it and I want the JTextArea to fit the size of the modal dialog.
If I pass in a long line of text then the JTextArea appears to get wider and
I have to scroll across the screen to see the text. I want it to wrap onto
the second line etc.
I must be doing something stupid!
Thanks, Kevin.

We're not talking about 1441. France didn't vote against 1441. We're
talking about the invasion "warrant" US wanted to squeeze out of UNSC.
France felt somewhat reluctant to sign that warrant because the
evidence US intelligence (sic!) produced was not so very convincing. At
the time. Later it turned out it was total bullshit. Dubya's setting up
an investigation right now. In 50 years we might get to know the...
conclusions.
> The question remains: Iraq failed to comply with the terms of UN 1441.
> What should have been the consequences of that?
Again? Well, let's hope this time you get it: the terms should have been
enforced. But not under US flag. Maybe (more than likely) under US boot.
But the flag should have been the blue UN.

- java/berkeley-db self-test hangHello!
The newly updated port of java/berkeley-db hangs during self-tests on one of
my machines:
dual FreeBSD/i386 6.1-stable - no hang
single FreeBSD/amd64 6.1-stable - no hang
dual FreeBSD/amd64 6.2-prerelease - hangs
There is little CPU use and all the process is doing, according to ktrace is
the repeated:
[...]

Rebuilding Java did not help... Would any Java and/or thread expert, please,
try to build the port with self-testing enabled and analyze any hang? Thanks

- JTable emulate a HTML Table?Hi,
I want to display a table of user inputted information as a table but I am
having problems formatting the layout as I want it. I have a fixed cell
width and want the cell height to adjust to fit the text entered by the
user.
I can set the widths but can only set a fixed height for a cell and am
unable to get text to wrap within it,
for example. Also with the fixed height, the single line cells would float
to the vertical center of the cell, not stay at the top. Can alignments be
set?
[date textfield][item textfield][description textarea][idenifier
textfield][cost textfield]
[submit button]
Date Item Description
Identifier Cost
12/12/03 Big Pan This is a description field that BPI420
$60
15:30 spans multiple lines an needs
to wrap. The cell height
should dynamically alter to
accomodate the text.
1/1/04 Aspirin This is a much shorter
AS123 $20
description
Am I able to do this and if so how?
Is there a better way to do this than with using a JTable? I tried doing it
with a gridbag layout but the consecutive items wouldn't stay aligned.
Please help!
Cheers

- reading values from JTableI am looking for a working example of a JTable that is constructed
with initial values in the cells, allows the user to change those values,
and reads the values out.
I've got three books on Swing, none of them show a write/read table.
I have no problem creating tables with nothing in some cells, and
reading the values out that the user entered.
Here is how I construct the tables:
DefaultTableModel model01= new DefaultTableModel(rowData,colNames);
JTable table01= new JTable(model01);
Any help greatly appreciated.

- create a bean on webapp startupHi,
Unsuccessfully web browsing makes me come here.
I wonder if it's possible to create a bean (used by <jsp:use-bean>) on
startup, also through web.xml. I've seen it is possible to launch a
servlet with <load-on-startup> xml element, but, as I believe I've
understood, it is NOT a persistent object.
So, i'm asking if :
- is this possible to create a persistent object through a servlet
lauched at startup ?
- is there a different way ?
