- The simplest way to show a large output string?Hi,
What I want to do is quite simple: I want to show a large output String.
The user then will press "OK"; then the output window disappears, and
the program continues.
The following code would be ok for me, but the real String I want to
show is very long (let's say 1000 characters and 100 lines), so I need
scrollbars...
Could you please tell me the simplest way to achieve this? Thanks in
advance for your help.
==========================
package gui;
import javax.swing.*;

public static void main(String[] args) {
String s = "hello";
JOptionPane.showMessageDialog(null, s);

- Download file problem in netscapeConsider this example..
I have a pdf file which is embedded in the browser and I have a
download link which is used to download that pdf file. When I click on
the download link, it is not functioning since it is the same url as
the embedded pdf and because the adobe reader is already there in the
browser it will automatically opens or the embedded pdf will goes off.
To prevent this scenario, we can use a mechanism. First create a
hidded iFrame in the same window using the following code..
<iframe style="DISPLAY: none" name="iframe1" src="">
Now make a small change to your download link so that the url target
is pointing to the hidden frame as shown below..
<a href="..." target="iframe1">Download</a>
This will solve the problem. However this method will not work with
Internet Explorer. For IE we can use another method and that method
can be choosen automatically by the browser.

- JSplitPane/JScrollPane Problem?Hey,
I'm writing an interface that has a verticle split pane, the top
and bottom of which both contain JScrollPanes with JEditor panes inside
each scrollpane. It sits within a JTabbedPane which is in a
JInternalFrame on a JDesktopPane.
JDesktopPane --> JTabbedPane --> Tab --> JSplitPane --> 2 ScrollPanes
--> 2 JEditorPanes.
The first EditorPane is a source area and the second is an error
output area. It's been working fine for me, which makes my current
dilema even worse.
I need to do the same format of error for an output tab so that
the output area is on top and the error output is on bottom. I took
the code from the previous working implementation and ported it and for
some reason it didn't work. The top component JScrollPane-->
JEditorPane does not show, but the bottom one does. Also, if I just
add the JScrollPane instead of the JSplitPane to the tab, it still
doesn't show, leading me to believe that it is a problem with the
implementation of the JScrollPane. Here are the code snippets of the
working and non-working portions of my code.
-----Working-----
source = new JEditorPane();
sourceError = new JEditorPane();
sourceError.setEditable(false);
JScrollPane scrollPane = new JScrollPane(source,
JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
scrollPane.setBorder(BorderFactory.createEmptyBorder());
JScrollPane errorScrollPane = new
JScrollPane(sourceError);
errorScrollPane.setBorder(BorderFactory.createEmptyBorder());
sourceSplit = new JSplitPane(JSplitPane.VERTICAL_SPLIT,
scrollPane,
errorScrollPane);
sourceSplit.setBorder(BorderFactory.createEmptyBorder());
-----Not Working-----
expressionOut = new JEditorPane();
outputError = new JEditorPane();
expressionOut.setEditable(false);
outputError.setEditable(false);
JScrollPane outputScroller = new
JScrollPane(expressionOut,
JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,
JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
outputScroller.setBorder(BorderFactory.createEmptyBorder());
JScrollPane outErrorScroller = new
JScrollPane(outputError);
outErrorScroller.setBorder(BorderFactory.createEmptyBorder());
sourceSplit = new JSplitPane(JSplitPane.VERTICAL_SPLIT,
outputScroller, outErrorScroller);
outputSplit.setBorder(BorderFactory.createEmptyBorder());
-----How They Are Added-----
tabFrame.addTab("Source", sourceSplit);
tabFrame.addTab("Output", outputSplit);
---------------
Any Ideas on why it isn't showing expressionOut?

- how do I encode image as stringI am trying to pass an image that I am manipulating in a java applet to
a javascript fuction, to be used there as either the source for an img
tag, or to save and/or print. Another possibility is to pass the image
up to a php script for further processing on the server. I know that
you can use ImageIO to save the image to a ByteArrayOutputStream, and
then use the stream's toString to get a string, but passing that string
to javascript truncates the image after the first 4 characters, due to a
null character (hex 0). I have been able to encode the string to
base64, but I do not know if anything more is needed to be done for the
javascript function to use it as an image.
I know that you can embed images in HTML by storing a special string
representation of the image in a javascript variable, but I do not know
what this format is. If I knew this format, I could encode the image in
Java, and then pass this string on. Any one know anything that could
help me?

- In Swing, using the RTFEditorKit, how to copy/cut Formatting *and* text to the Clipboard?Hi Folks:
Any idea on the best approach to support copy/cut of all style/formatting as
well as plain text for a JTextPane? I googled quite a bit and located a
word processing program that supports JTextPane but they specifically
mention it only places "plain text" to the Clipboard and ignores the
formatting information when transfering.
I was thinking about implementing the Transferable interface and using the
Clipboard.setContents(..) method but I'm not sure yet by which procedure I
implement the getTransferData() as it wants to return an Object. I could
use a byte[] stream and return a ByteArrayOutputStream who's contents would
be filled with the Document's data (ie, plain text *and* the control/style
information). I just don't know if that would work yet but I plan to try
that.
Seems like there's very little (if anything) mentioned in the sun
developer's forum on how to do this as well as in google...
First of all, is Java's support for RTF still somewhat "primative"??? I
have a full blown word processor going which looks like Word and supports
font changes, size changes, find/replace operations, etc... It's just that
the cut/copy only transfers the plain text (despite my attempts to call
setContentType("text/rtf")) to the clipboard and not the style information.
thanks for any insight, Theron

- help with multidimensional arraysHi
I am a newbie in the world of Java programming. I have recently started
learning the language. Apart from other hickups one which has been on
my nerves is the concept of multidimensional arrays. As far as my
understanding goes these are array of arrays.
1. WHAT DOES THIS MEAN?
2. ARE ARRAYS RESTRICTED TO THREE DIMENSIONS ONLY OR THERE IS ANY OTHER
LIMIT AND HOW DOES THREE DIMENSIONAL OR HIGHER DIM ARRAYS WORK?
Does two dim arrays represent a pigeon hole type thing in which you
find a particular hole by giving row and column address e,g. box
located at row 5 and column 2.
3. IF THIS CONCEPT OF TWO DIMENSIONAL ARRAYS IS CORRECT THEN HOW DOES
THREE DIMENSIONAL OR HIGHER DIM ARRAYS WORK.
Presently I am going through a book written by Herber Schildt known as
Java 2 complete reference, Following is a program which demonstrates
the two dim arrays. I am unable to understand the make of the program
may be so many loops are troubling me. I am especially confused about
the functioning of the question mark steps please help me out there.
// Demonstration of concept of two dimensional arrays
class twoD {
public static void main (String args [ ]) {
int [ ][ ] twoD = new int [4][5];
int i,j,k = 0;
for (i=0; i<4; i++)
for (j=0; j<5; j++) {
twoD [i][j] = k; ?
k++; ?
}
for (i=0; i<4; i++) {
for (j=0; j<5; j++)
System.out.println (twoD[i][j] + " ");
System.out.println();
}
}
}
4. HOW AND WHY SO MANY LOOPS ARE FUNCTIONING TOGETHER?
(While replying please be patient and keep in mind that u r talking to
an absolute beginner in the world of Java programming)

Can't you just add a (custom) annotation, e.g. "@JavaBean", and use
apt to generate the getters/setters? (Or possibly the newer
javax.annotation* stuff?) You could add options to such an
annotation e.g., read-only.
Then add the one extra line in your ant script to build code.
Note JavaEE defines many such annotations, including for an
MX Bean. Adding a standard annotation "@JavaBean" doesn't seem
like it would be that much effort, for a large convenience payoff.
<waffle>
Like Lew I use an IDE that does that for me. Still, I don't like
dependencies on particular tools that provide special features, if
the language could easily support them with little effort.
OTOH as others have pointed out in previous threads, the JavaBean
spec is rarely used, so maybe adding more standard annotations
isn't worth it.
If the OP thinks it should be used, create or modify a JSR for this
feature; if enough others agree it will be added.

- CVS checkout doesn't work in Eclipse v3.0.1Hi,
Since the CVS functionality of NetBeans doesn't appear to work for
me, I'm trying Eclipse. However, the CVS functionality of Eclipse
doesn't appear to work either. When I try to do a CVS checkout in
Eclipse, a "project" does get created in my workspace, but the
contents of the CVS modules aren't actually in the project. Now, the
contents of the module are only directories to this point, because I
was looking to work on the module with Eclipse. Should this be a
problem? Should I add a least one file to the project before Eclipse
will properly checkout the module with all its subdirectories?
Thanks,
Jason

- How Can I put XSL tag inside HTML form tag?Hello Dudes,
Sorry I couldn't find a XML/XSL group
I can only post these groups close to my subject.
In JSP (Java Server Page) you can do something
like this
<%
String v = myBean.getValue();
%>
<form .... >
<input name="myTag" value="<%= v %>">
</form>
You can do the similar thing in PHP.
But when I try in XSL I got error.
I have an XML file
<myTag attribute1="value1" />
Now I want to transform it into HTML form tag used XSL template
But XSL doesn't like this
<input name="myTag" value='
<xsl:value-of select="@attribute1" />
'></input>
How can I solve this problem?
Thank Q very much in advance!

- Critical Problem with Tomcat 3.3.1 and SSLHello,
I am having a serious problem trying to set up SSL on Tomcat 3.3.1 on
Windows 2000. I am following the jakarta guidelines exactly as they
propose, but I am having absolutely no luck. What am I doing wrong?
Here is the procedure I follow:
First, I run the following command -
keytool -genkey -keyalg rsa -alias name -keystore name
- I then answer the questions. I tried setting the common name as
my name, and a second time as the the URL used to access the site in
question, ie: sitename.com
Then, I issue the following command -
keytool -certreq -keystore name -alias name -file name.csr
Next, I send the name.csr file to the CA, and recieve 3 certificates.
The 3 certificates I receive are RootCert.cer, IntCert.cer and
NewCert.cer. So, I then issue the following commands in this order:
keytool -import -trustcacerts -file RootCert.cer -alias rootcert
-keystore name
keytool -import -trustcacerts -file IntCert.cer -alias intcert
-keystore name
keytool -import -trustcacerts -file NewCert.cer -alias newcert
-keystore name
After each command I receive confirmation that the certification was
properly inserted. I then copy the 'name' file to TOMCAT_HOME/conf
and edit the server.xml file. I add the following lines to the
server.xml file:
<Http10Connector
port="8443"
secure="true"
keystore="c:\tomcat\conf\name"
keypass="password"
clientauth="false"/>
Now, I restart tomcat and assume that everything should be in order.
When starting tomcat via the batch file, I see that an Http10Connector
is correctly sitting on port 8443. So, I try accessing the site
normally, and everything works fine. However, if I attempt an HTTPS
request to the site, I receive a page cannot be displayed error. This
is strange, because I figured that at this point it should work.
Well, I then attempted to access it manually by addressing
localhost:8443 .... this is where I noticed a problem. Once the
request is sent to Tomcat, Tomcat throws the following exception:
PoolTcpEndpoint: Handshake failed
javax.net.ssl.SSLException: Unrecognized SSL handshake.
at com.sun.net.ssl.internal.ssl.InputRecord.read(DashoA6275)
at com.sun.net.ssl.internal.ssl.SSLSocketImpl.a(DashoA6275)
at com.sun.net.ssl.internal.ssl.SSLSocketImpl.a(DashoA6275)
at com.sun.net.ssl.internal.ssl.AppOutputStream.write(DashoA6275)
at java.io.OutputStream.write(Unknown Source)
at com.sun.net.ssl.internal.ssl.SSLSocketImpl.startHandshake(DashoA6275)
at org.apache.tomcat.util.net.JSSESocketFactory.handshake(JSSESocketFactory.java:270)
at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:479)
at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:516)
at java.lang.Thread.run(Unknown Source)
ThreadPool: Caught exception executing
org.apache.tomcat.util.net.TcpWorkerThread@3a8602, terminating thread
java.lang.NullPointerException
at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:498)
at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:516)
at java.lang.Thread.run(Unknown Source)
What is going on? Luckily, I have access to a CA, so this process
isn't costing me anything, however I have attempted this multiple
times with various certificates and various settings on the
certificate and I always get this same exception. What's more, I
tried creating a self signed certificate and I still get this
exception. Am I doing something wrong? I have scoured the net
countless times and it seems like all the instructions say the same
thing. When I search for this error, none of the recomendations fit
my situation. If no one knows how to fix this, could someone please
recomend where I can go so that I can find the answer to this problem?
Please help me out, this is driving me nuts. Thanks in advance,
Dan

java-programmer, UK Postcodes anyone know of a service ?
Hi
My latest web application provides a search facility.
You sign up as a member and get a free entry in a searchable database.
I would like to offer a postcode search so that if someone is looking for a
particular service they can enter a postcode and return results within a number
of miles of the input postcode(s). I have seen this sort of search on a number
of sites to date and I was wondering if anyone knows of a web service or other
online service that will accept a post code (and some other params of course)
and return a list of postcodes within a parameters distance.
Once I have the list I can search my own database for results.
The service must be available over the network, I'm not intetested in static
databases that I have to install on the server (well I might be if they were
FREE :-).
Has anyone implemented such a thing ?
Does anyone know of such a service ?
Has this got anything to do with the group ? well I suppose not other than I
write in Java.
Cheers
anyway
Duncan

I think you have to get this data from Royal Mail
(http://www.royalmail.co.uk). They have a variety of services that you
can view on their website (I think the one you need is called Postzon).
However, I don't think they have a networked service. You have to buy
CDs/DAT tapes with the data on. This data doesn't change all that quickly
but you can get a subscription for yearly or quarterly updates. I don't
think it is particularly expensive.

That information is copyright, and you will have to pay for it. The Post
Office don't want people going around using their service, and if they
do, they certainly shouldn't be addressed properly. The organisation
knows where its strengths lie, and delivering letters ain't amongst them.
They have a Postcode/Address Finder page that is gracious enough to
permit twelve searches in any 24 hour period, if you go through the
registration procedure (I haven't bothered). All the links for further
information on the page appear to link straight back. Genius.
https://www.postoffice.co.uk/portal/po/addressfinder?pageId=pol_login&catId=20700386&_requestid=53918&cs=1
The common commercial solution used to be QAS' QuickAddress Nearest. In
addition to locations of postcodes, it would also take into account
natural barriers. So it didn't suggest somewhere in Newport for someone
who lives in Clevedon, say.

Yea, I saw that, OK if I only get 12 hits a day on my search engine I guess
otherwise useless.
>The common commercial solution used to be QAS' QuickAddress Nearest.
Nice one, actually it appears that they have something called QuickAddress
nearest for the web
http://www.qas.com/uk/products/internet/web-nearest.asp
Guess I'll have a look at that.

There was a discussion of this very topic on one of the MySQL mailing lists
just the other day. I didn't follow it very closely but I seem to recall
that the people involved listed a few possibilities, although I don't think
any of the satisfactory ones were free. If you go to http://lists.mysql.com/
and enter the following in the search box, you should find the discussion:
Search term: "UK postcodes"
within: all lists
matching: all of the words
since: 30 days ago

I bought a file with all uk postcodes mapped to co-ords which you can then
use to get straight line distances in your searches. It cost me ?50 which
is far cheaper than you'll get by a per-search fee via a web service.

Thanks for that, lot's of interesting points there.
It does seem that these days, in this country, EVERYTHING has to have a price.
You would have thought that Postcodes are (or should be) public property.
Ho Hum

- passing RequestPath to error page from web.xmlHi,
I have pointed any errors to Error.jsp in my web.xml file (as shown).
<error-page>
<error-code>500</error-code>
<location>/Error.jsp?id=500</location>
</error-page>
As you can see I also pass the type of error, is there any way I can
pass the RequestPath that resulted in the error in the first place?
Cheers,

- Tomcat on Windows: JAVA_HOME & -Dsun.io.useCanonCaches'Apologies for posting this here, but I couldn't find any Tomcat user
forum.
A colleague is currently trying to run Tomcat 4.1.30 on Windows 2000
Professional. She first installed JRE2 1.4.2_08, and set %JAVA_HOME%
to the directory C:\j2re1.4.2_08 - I've run "java -version" and it
works fine.
(%JAVA_HOME%/home is in the path correctly).
She then installed Tomcat to C:\jakarta-tomcat-4.1.30.
However, when she runs catalina.sh start, she gets the following
error:
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
Using CATALINA_BASE: C:\jakarta-tomcat-4.1.30
Using CATALINA_HOME: C:\jakarta-tomcat-4.1.30
Using CATALINA_TMPDIR: C:\jakarta-tomcat-4.1.30\temp
Using JAVA_HOME: C:\j2re1.4.2_08
'-Dsun.io.useCanonCaches' is not recognized as an internal or external
command,
operable program or batch file.
I've even tried adding the following to catalina.bat without success:
if not "%JAVA_HOME%" == "" goto gotJavaHome
set JAVA_HOME=C:\j2re1.4.2_08
:gotJavaHome
Can anyone see where we might be going wrong?
Cheers,

You should simply use UrlClassLoader and have the system classpath not
include your code that needs to be reloaded, and the URLClassLoader
have the path that DOES need to be reloaded (creating a new instance
of that class loader every time you need to reload the class)
That way, Result will be properly loaded by the System class loader,
and your reloadable class wont.
Hoep this helps,
Daniel.

Change the path setting so it reads:
PATH=C:\Program File\java\Jdk1.5.0_09\bin;C:\oracle;...
The OS looks for commands on the PATH from left to right, so starting
with java, then oracle, and so on.
Besides this. The classpath setting isn't really needed. This is a
general note which might bring in problems later. If you don't have a
real need for it, simply remove the classpath setting. You can still
pass it to the java command using the "-classpath" switch.

- Problem in configuring SSL in Tomcat5.5Hi,
I have Tomcat5.5 and J2sdk5 installed on my system. I wanted turn on
SSL services in tomcat. I went through the Tomcat Documentation and
did it exactly. I modified server.xml as below,
<!-- Define a SSL HTTP/1.1 Connector on port 8443 -->
<Connector port="8443" maxHttpHeaderSize="8192"
maxThreads="150" minSpareThreads="25"
maxSpareThreads="75"
enableLookups="false" disableUploadTimeout="true"
acceptCount="100" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS" />
I also created certificate using keytool with default password as
"changeit" and alias as "tomcat".
I restarted the tomcat services too, and then tried to access the page
but i am not able to access it using https connection. Where as i am
able to access same page using Http connection.
Secondly, I am not able to access default tomcat Page too using Https
connection. Everything works fine in case of HTTP connection.
Following is the way iam trying to acces the page,
https://localhost:8443
Can any one help me out to find the problem.
I have IE 6 with SP2 installed on my system.
Thanks

- Getting JAVA_HOME at runtimeHello,
The Java ports infrastructure provides JAVA_HOME on build-time to
port's Makefile. But is it possible to get this variable from
/usr/local/bin/java at runtime?
How to change the Java version for a port at runtime in the rc
script? It is possible to set the preferred JDK in
/usr/local/etc/javavms but then JAVA_HOME still needs to be
set manually.
I would like to avoid hard-coding the JAVA_HOME at build time in
the rc scripts.
Any idea?

- Multiple installs of JDKWhen you do a silent install of the JRE you have the option to pass
PRIVATE=1, resulting in an install which doesn't check the registry
for a prior installation, and doesn't update the registry. You can
therefore have more than one install of the same JRE.
I need to find a similar capability for the JDK, but can't seem to. We
get rc=1603 on the second JDK install.
How can this be done...?
JDK >= 1.5.

- Running server-side Java on FreeBSD in production environments
So, I've seen a few mentions here of folks using Java server apps on
FreeBSD in production. I've been very happy to watch the progress by the
Java team on the native JDKs from the sidelines, as well as the
improvements to libc_r and such that have been MFC'd, but I'm curious as
to whether the consensus on this list is that it's ready to be used for
production. Anyone want to share good success or horror stories? We're
trying to determine whether the apache.org box can start to run our own
software. :) Speed is definitely less important than proper functioning.

- JTable and Custom Default Cell Editors
From: "Erica Wheatcroft" <email***@***.com>
Subject: JTable
Date: Thursday, January 20, 2005 4:17 PM
HI -
I have a jtable that uses two custom default cell editors to create combo
boxes for two of the the 4 columns. If the user selects another value from
either of the combo boxes i want to know that so i can indicate a save must
occur. I'm not sure what event i should listen to? Does any one have any
suggestions?
Thanks in advance.

- An efficient computation idea. Please commentHi,
In my program I evaluate long trigonometric polynomials a lot! For example,
final int N = 1000;
double[] c = new double[N];
// Populate c
double x = .5, sum = 0.0;
for (int i = 0; i < N; i++)
sum += c[i]*cos(i*x);
And this function is evaluated very many times (about 100,000). So why not
create a java snippet, compile it, load it as a class and use the compiled
version. So I would have something like;
String sum = "0"; // A String buffer, of course...
for (int i = 0; i < N; i++)
sum += "+" + c[i] + "*cos(" + i + "*x)";
sum += ";";
I think it's a pretty cool idea. But before I implement it, I would like to
know what you think about it!
Thank you in advance!

OK, I had never done this before -- built a package from a port. So
I did this on the base machine and then copied it into the jail and
did a pkg_add like so
# pkg_add -P /usr/public -v jdk-1.5.0p4_1.tbz
as I wanted it installed in my local policy dir /usr/public (which
gets mounted RO in every jail). My 1.4.2 java on my other jail
server is installed like this (but was built inside the jail many
moons ago).
Now, when I try to run java I get
# java -version
Error: could not find libjava.so
Error: could not find Java 2 Runtime Environment.
#
Java is in /usr/public/jdk1.5.0/ (the same as my 1.4.2 on the other
server which is in /usr/public/jdk1.4.2/). libjava.so is inside the
lib dir and I thought that java was referential to itself so it could
find its libraries.
I also tried setting JAVA_HOME and JRE_HOME though I have not had to
do that in a long time.
The new 1.5 jdk is registered in the javavms file .
When I run the javavm script with /bin/sh -x it does run the correct
java and running it with an explicit path does not help.

- Initialize managed bean with header information?We use Netegrity's SiteMinder for SSO security on all web apps.
Although SiteMinder handles security for accessing the application
itself, restrictions to certain functions and data are handled within
the application based on user type.
The user information (such as name, type, etc.) are passed in from
SiteMinder via header variables. ie:
hddr_user = Joe Blo
hddr_group = Admin
hddr_phone = 555-555-5555
I'm looking at different designs to capture all of this user
information from the headers at one time and store as a bean in the
user's session (so as to not need to continually reference the header
information).
Does anyone know if you can create a managed bean (ie. User) that is
initialized with header information (by using the configuration file
w/ value-binding expressions)?
