- AccessControlException
The following is a snippet from a method in an applet RSSTree:
private Document getOPMLFile(String OPMLFileName) {
Document OPMLFile = null;
try {
URL u = new URL(getCodeBase(), OPMLFileName);
try {
BufferedReader br = new BufferedReader(new
InputStreamReader(u.openStream()));
if (br != null) {
try {
Builder parser = new Builder();
OPMLFile = parser.build(br);
}
.
.
.
This method is called out of RSSTree.start(). Document & Builder are
classes in the open source XML processor com.nu.xom. I get the following
error when parser.build(br) is executed:
java.lang.ExceptionInInitializerError
at RSSTree.getOPMLFile(RSSTree.java:63)
at RSSTree.start(RSSTree.java:31)
at sun.applet.AppletPanel.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
Caused by: java.security.AccessControlException: access denied
(java.util.PropertyPermission
org.apache.xerces.xni.parser.XMLParserConfiguration write)
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)
at java.lang.System.setProperty(Unknown Source)
at nu.xom.Builder.<clinit>(Unknown Source)
If I replace the bad line with a loop to read the the stream myself and
write out the lines, I get the XML I expect.
Without seeing the source for XOM can someone give me an idea as to why I
have an access problem when going through XOM but don't when the applet
reads directly?
Thanks.

- Learning Apache Ant, problems with Swing(?)I'm attempting to learn Apache Ant (apache-ant-1.6.1); OS Linux Fedora
Core 2; j2sdk1.4.2_04. I appear to have problems with Ant + Swing, but
each work separately.
The following is my first build file (copied from the web).
<?xml version="1.0"?>
<!-- build file for lesson 1 -->
<project name="tutorial" default="build" basedir=".">
<target name="build">
<javac srcdir="." />
</target>
</project>
Works fine on a simple Java program, e.g.
import java.io.*;
public class Hello {
public static void main(String args[]) {
System.out.println("Hello");
}
}
However, when I progress to anything involving Java Swing, I get
compilation errors like:
[javac] /home/jc/java/classes/anttest/GuiScreens.java: In method
`GuiScreens.main(java.lang.String[])':
[javac] /home/jc/java/classes/anttest/GuiScreens.java:24: error:
Can't find constructor
`javax.swing.JFrame(Ljava/lang/String;Ljava/awt/GraphicsConfiguration;)'
in type `javax.swing.JFrame'.
[javac] frame[j][i] = new JFrame("Config: " + i,
gc[i]);
/This program compiles okay using javac./
(BTW jc@localhost~/java/classes/anttest>$ echo $ANT_HOME
/usr/apache-ant-1.6.1
jc@localhost~/java/classes/anttest>$ echo $JAVA_HOME
/usr/java/j2sdk1.4.2_04)
Any ideas?
TIA,

- database connection pooling in tomcat 3.3.1Hi,
I have a webapp which uses database connection pooling setup just like
the tomcat how-to suggests. But, I can't seem to get it to work on
tomcat 3.3.1. I couldn't even find any how-tos or guidances on it
anywhere. Is it supported ?
I get a javax.naming.NoInitialContextException: error when I set it up
in the conf/app-myapps.xml like the 3.3.1 doco suggests.
Appreciate any help on this.
Regards,

- jsp servlet code seperation confusionI posted this on the .help NG but I believe you folks could probably
provide more of an accurate answer considering the help group is
targeted towards true beginners.
Okay, where I am employeed I have the options of programming with
Microsoft Technologies and Java specifically J2EE. I have been
investigating the task of learning Java for about the last 3 to 4
months. I am a ASP.Net developer fulltime at work with C#. I was new to
OOP when I started into .Net about a year ago and am getting better.
However, our corporation uses Java as a National standard and I am
looking to advance some day and need to learn Java. Furthermore, where I
live, KY there are very few jobs for technologies other than .Net and
Java. No PHP or ColdFusion.
In the last couple of years this code seperation theory has overloaded
the programming world. .Net does it with what's called code behind. In
my research of Java the only things I see that reference code seperation
is servlets (I am sure J2EE and EJB contribute also). However,
everything I have read on servlets reference outputing HTML back to the
browser via the HttpServletResponse and Request objects.
My question, why in the world do they consider outputting HTML back to a
browser via a servlet considered code seperation. Furthermore, it
seems very time consuming and difficult to hand code complex layouts in
HTML and incorporate/format it for a servlet.
Can someone please explain or direct me to a resource where I can
understand why using servlets at any point in an application would be
better than jsp or even applets? Sometimes it's hard enough to design
complex layouts with the assistance Dreamweaver for example.
Thanks for any insight you can provide, I have read hundreds of pages of
information concerning this and trying to compare it with the my current
knowledge in the .Net world.

- <defunct> processesI've got a problem with <defunct> (zombie) processes on Linux...
I'm running child processes using Runtime.exec() and it usually goes well.
But just sometimes (undefined sometimes), process finishes as defunct. Is
there anything I can do about it? I suck out both inputStream and
errorStream, check Process.exitValue(), but it stucks on Process.waitFor().
I even try to suck these streams in separate threads, but it doesn't help.
I had the idea to detect if the process has stucked, and then try from
another thread to Process.destroy(), but it didn't help! Destroy does
nothing, process is still defunct, and waitFor() blocks it again... There
are no more methods in class Process to try, and I've already tried all the
combinations of existing ones...
Newsgroups and web are full of similar questions, but no answer. They all
say that a process is zombie if it is finished, but parent process hasn't
yet read the exit code. But I do read exitValue, and I also do
Process.waitFor(). Can I consider this a bug in Java VM?
Where could find the solution? Which direction should I go? I've been trying
for months, but no results...
Now, this is the latest version of code, as seen on java.sun.com...
{
...
Process process = Runtime.getRuntime().exec(commandLine);
inputVacuum = new TextVacuum(process.getInputStream());
errorVacuum = new TextVacuum(process.getErrorStream());
process.waitFor();
int exitValue = process.exitValue();
...
}
public class TextVacuum extends Thread {
private BufferedReader reader;
private StringBuffer buffer = new StringBuffer();
...
public TextVacuum(InputStream inStream) {
reader = new BufferedReader(new InputStreamReader(inStream));
start();
}
public void run() {
try {
char[] cbuf = new char[4096];
int numRead = reader.read(cbuf);
while (numRead != -1) {
buffer.append(new String(cbuf, 0, numRead));
numRead = reader.read(cbuf);
}
}
catch (IOException e) { }
finally {
try { reader.close(); }
catch (IOException e) { }
reader = null;
}
}
...
}
Thanks!

- JSP questionshave some questions about JavaServer Pages to ask
1. I made several input fields for user to input the height, width and
other stuff to create a table. how can I make the font in color red in
first row and first column automaticly and font in other rows and
columns remain the same color?
2. I want to add a title inside the table that need to colspan the
rest of the table. Becasue I don't know what # the user will input for
columns, so I can't set it before user input. so plz help me on this.
3. Randomly place an input field in one of the cells ?a different
cell on each refresh. If the user enters the correct product there and
changes the focus (by clicking outside the field), a Javascript
provided by the jsp page checks the answer and makes appropriate alert
My jsp file looks like this:
<HTML>
<head></head>
<BODY>
<%
String s2 = request.getParameter("Bsize") ;
s2 = s2.trim();
out.print("<table bgcolor=silver border= ");
out.print(s2);
out.print(" ");
String s3 = request.getParameter("Bcolor") ;
s3 = s3.trim();
out.print("bordercolor= ");
out.print(s3);
out.print(">");
String m1 = request.getParameter("mName") ;
m1 = m1.trim();
int M = Integer.parseInt(m1);
String n1 = request.getParameter("nName") ;
n1 = n1.trim();
int N = Integer.parseInt(n1);
String s = request.getParameter("FullName") ;
s = s.trim();
out.println("<font color=red size=6>");
out.println(s);
out.println("'s table is: </font>");
out.println("<tr colspan= ");
out.print(m1);
out.println(">");
out.print("<th> Numbers </th> </tr>");
for (int i =1; i<= M; i++ )
{
out.println("<tr width= 10 >");
for (int j =1; j<= N; j++ )

out.println("<th >");
out.println(j * i);
out.println("</th>");

Oh, probably the one where in the US at least, the National Institutes
of Health do exactly that, every business day.
Tim lives in one of the civilized countries where they have Public
Health for all, and of course there, the government is money ahead
if new drugs cut down the total balanced cost of treating the ill and
compensating for the other disbenefits to society that illness causes,
even at the tax base level, and if they had any brains would realize
that and fund research accordingly.

Uh no, because those leave control with the language. Most people who
defend the goto so vehemently,are, with modern languages like Java,
simply are using it to emulate something else available within the language.
Let's see, in the last 10 years, I have written about 1,000,000 lines of
C code, the number of actual goto's in there, none. During that time, I
viewed probably 40,000,000 more lines, which contained maybe 20 gotos.
Shows how little goto is actually needed. Of those 5, were code that
was complex trying to do something simple, usually the reason I was
looking at it, was because it wasn't working (poor design). Five more
were instances where you had the jack-of-all-procedures, where the
programmer had written a bunch of procedures in one block of code (again
poor design). They used goto to make the thing work. The remaining
ones, were places where the programmer had written themselves into a
corner, and under pressure of getting the thing to work, used goto to
bail out (again poor design).

- Baffling class not found problemHello, I'm using Java 1.3 with WebLogic 5.1 on Solaris. I have these
files:
cms/system/CMSException.class
cms/system/Constants.class
cms/system/InitServlet.class
cms/system/Log.class
When I include this line on my JSP page
<%@ page import="cms.system.*" %>
everything compiles fine. As does this line
<%@ page import="cms.*" %>
but when I try
<%@ page import="cms.system.Constants" %>
(r using any of the 4 class names above) I get the error:
Compilation of '/tmp/support/jsp_servlet/_www/__temp.java' failed:
/tmp/support/jsp_servlet/_www/__temp.java:16: Class
cms.system.Constants not found in import.
probably occurred due to an error in /www/temp.jsp line 1:
<%@ page import="cms.system.Constants" %>
How can this be? The perms on the files above are all 775. Can anyone
think of an explanation for why these files can't be found?
Thanks, - Dave

- Whatever happened to PvdL?My curiosity about Hotjava now sated, what of Peter van der Liden? I recall
that he used to be pretty active on Usenet and quite a prolific author and
Java advocate.
As I recall he used to author the Java FAQ (which now 404's). I liked his
writing style (dating to the ugly fish book) and the Just Java series. The
6th edition came out in 2004 and no errata has published since January
2005.
Is Mr. van der Liden still active in the Java community? I realize he's no
longer with Sun and without treading into personal matters, did he have a
falling out with the people there? In spite of being published by Sun, his
Java books did contain quite a few barbs about misfeatures in the language.

- Grab common name from https://[ip]Hello,
I checked around on here a bit, and was unable to find an answer to
this one by searching for the error message. I'm hoping someone here
can help me with this issue.
I am attempting to gather the common name from an SSL certificate for a
given IP address. Following is the code I am using thus far (two
classes being used):
IP_Justification.java:
import java.net.*; //for https connection
import java.io.*; //for input parsing
import javax.net.ssl.HttpsURLConnection;
public class IP_Justification
{
private String IP; //IP address to search
private String domain; //common name returned by viewing IP via
https://ip
//default constructor
public IP_Justification()
{
throw new IllegalArgumentException("Please provide IP and domain");
}
//create with IP provided
public IP_Justification(String ip)
{
IP = ip;
domain = "";
}
public void getDomain() throws IOException
{
String urlToCheck = "https://" + IP;
URL techURL = new URL(urlToCheck);
System.out.println("URL created: " + techURL);
HttpURLConnection techUrlConn =
(HttpURLConnection)techURL.openConnection();
System.out.println("HttpURLConnection created" + techUrlConn + "\n");
techUrlConn.connect();
}
}
IPJustMain.java
import java.io.*;
public class IPJustMain
{
public static void main(String[] args) throws IOException
{
IP_Justification testing;
testing = new IP_Justification("64.233.167.99");
testing.getDomain();
try
{
}
catch(Exception e)
{
System.out.println("Start of output - Exception block");
System.out.println(e.getMessage());
System.out.println("End of output - Exception block");
}
}
}
Following is the output received when running IPJustMain:

Press any key to continue . . .
I fully expect to have an exception thrown, and am hoping to be able to
parse that for the information I require. The problem I am running
into is the exception itself:
Exception in thread "main" java.io.IOException: HTTPS hostname wrong:
should be
<64.233.167.99>
It seems to be responding with the URL I pass to it, and not the common
name for the SSL at the specified IP address.
Anyone happen to know if there is a way around this or if my code is
flawed in someway?
Thanks for any help that can be provided!

- Midlet TextBox-------------------
TextBox tb = new TextBox("title", null, 5, TextField.DECIMAL);
tb.addCommand(new Command("Ok", Command.BACK, 0));
tb.setCommandListener(this);
Display dis = Display.getDisplay(this);
dis.setCurrent(tb);
-------------------
The code above shows (in my mobile Sony Ericsson K300i) a TextBox with 2
Commands "Ok" and "Ok".
If TextBox is empty of chars, first "Ok" is grayed but second not.
I suspect that the first Command "Ok" is part of TextBox (Screen) and
when I press it, it does nothing and commandAction method does not run.
Only when I press the second Command "Ok" commandAction method runs.
So, first "Ok" is "feature" of my mobile or it is in MIDP Specification?
If the second, how can I get access to this Command?

java-programmer, Can we change enctype dynamically??
Hello all,
Can we change enctype in the form tag using javascript
document.formname.enctype = 'variable' variable being
multipart/form-data or application/x-www-form-urlencoded. I can do
this in Netscape7 not in IE6 ??
My problem is when I am in the rendered page of type
mulipart/form-data, I have to call another servlet (which process
regular form fields only). When I do that it breaks.
If I use all my servlets to process enctype=mulipart/form-data jsp's
is there any performance or any kind of issues???
Any help will be appreciated.
Thanks - gsr

- jsp:setProperty, java.io.File, and I thoroughly confusedHi,
I'm writing a webapp based on JSP technology. I've been doing
some reading and from what I've read, it isn't possible to use
jsp:setProperty to set a File property. So, I created a BeanInfo class
for the Bean I had the File variable in. I also created a class that
extended PropertyEditorSupport to assign the BeanInfo class to the
Bean. But, those don't appear to get called. I CAN, however with
Tomcat 5.0.28 on Windows XP, simply set a File property with
jsp:setProperty. The Bean ends up looking for the file in the Tomcat
bin directory, and I can thus set a relative path to the file. So, I'm
completely confused. What is going on? Is this expected behavior?
Thanks,
Jason Mazzotta

- Why does this query take forever?For some reason, I have a rather large (to me) query, with numerous inner
joins, accessing a remote server, and it is taking about twenty times longer
than most queries to the same database.
The query itself is built programmatically within my application, and
example of which is below. I am hoping someone in the group may have some
insight into why this query is so slow, suggesting perhaps a better
structure for it, such that I can go back in and rewrite my code that
creates such queries.
Thanks in advance, Ike

- optimizing java compilerHi!
As the -O option of javac does nothing and Sun obviously think it can affort
not to do so, which compiler is known to optimize bytecode well? Jikes?
eclipse? What about AspectJ?

- Vowel Counter ProgramHey,
I am trying to write a basic program that counts how many lowercase
vowels and non-vowels are in a string. I'm trying to use the
StringTokenizer function. Also, I have to prompt the user again by
using a do while loop. The string ends with the string "DONE".
Here's my code. If anyone could help me, please do. Thanks.
import cs1.Keyboard;
import java.util.StringTokenizer;
class vowelCounter;
{
public static void main(String[] args)
{
// Initialize Answer to Zero
int answer = 1;
do // Start the do loop
{
// Declare all variables and set counters to zero
int aCounter = 0;
int eCounter = 0;
int iCounter = 0;
int oCounter = 0;
int uCounter = 0;
int nonVowelCounter = 0;
String line, temp;
int letter;
StringTokenizer tokenizer;
// Prompt the user for String and read string
System.out.print ("Please enter text (Type DONE to quit):
");
line = Keyboard.readString();
while (!line.equals("DONE"))
{
tokenizer = new StringTokenizer (line);
while (tokenizer.hasMoreTokens())
{
temp = tokenizer.nextToken();
letter = temp.length();
for (int i=0; i<=letter; i++)
{
// Increment vowel counters
if (line.charAt(i) == 'a')
aCounter++;
else if (line.charAt(i) == 'e')
eCounter++;
else if (line.charAt(i) == 'i')
iCounter++;
else if (line.charAt(i) == 'o')
oCounter++;
else if (line.charAt(i) == 'u')
uCounter++;
else
nonVowelCounter++;
}
}
line = Keyboard.readString();
}
// Print out number of vowels and non-vowels
System.out.println ("Number of 'a': " +aCounter);
System.out.println ("Number of 'e': " +eCounter);
System.out.println ("Number of 'i': " +iCounter);
System.out.println ("Number of 'o': " +oCounter);
System.out.println ("Number of 'u': " +uCounter);
System.out.println ("Number of non-vowels: "
+nonVowelCounter);
// Prompt the User About Continuing
System.out.print ("Do you want to continue?
(0=exit/1=continue) ");
answer = Keyboard.readInt();
System.out.println ("");
}while (answer == 1);
}
}

- Creating MouseEventsHi,
I'm trying to dispatch interaction with a touch screen as a MouseEvent, but
I can't get java to register an event on components like the drop-down list
from a combo box, or invisble components that accept normal mouse click
events.
Thanks,
Andrew

didnot want to install anything jre like in client )
is it possible.

- Make Java plugin SysTray icon visible ?I have a java plugin (for IntExp) browser which is currently for version 1.4.2_14b05
On some machines I noticed that the plugin shows an icon in the SysTray
on others not. How can I hide/unhide this Java plugin SysTray icon ?
Where are the files for this java plugin physically stored (in which directory) ?

- Open Source quality better then closed?hi...
i just wondered, does the fact you write a product as open source,
forces you to write better code, in the hopes (fears?) that who ever
may see you code in the future will be impressed (shocked?)
