- 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

- 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?)

- 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,

- getting starting with ...... Java
I am newbie of sorts: I'm familiar with java to a some extent, but I have
never had the chance to use it. Which means, I'm not as comfortable with
it as I am with other languages (php,asp,python,c,perl,etc). What is the
best way to get comfortable? Is there any particular direction I should be
heading? I never read a book from start to end, unless it's a novel, so
with other programming languages I've learnt the fundamentals, and the
bits and pieces here and there as needed. Database connectivity, web
(server based) apps are of interest as most work I do is related to these.
Current projects include pulling stats from a database (Postgres,mysql) in
python and, a web credit card payment system in php. Im also maintaining
one of our "legacy" systems in perl.
I have lots of time, and I want use doing something productive in java,
that is my aim.
Directions will be helpfull....

- 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);
}

- illegalMonitorStateExceptionhello everybody!
it is well known that one has to be in the monitor of an object to call
myObj.wait(), f. E. by putting it into a synchronize(myObj) block.
my questions:
- is it bad programming style to just catch the exception without doing
the synchronize? because if i do this my program still perfectly does
what it should.
- why does this exception exist?
thanx a lot,
moritz.

- Corrupted JPEG: DataInput/OutputStreamHi!
I download a JPG and write it to disk; this is rather old code which
certainly worked. The only thing I'm aware of that changed is JDK 1.4 ->
1.5b2. The written file is corrupt:
URL u = new URL ("http://foo/bar.jpg");
DataInputStream in = new DataInputStream
(u.openConnection().getInputStream());
File f = new File (foo);
FileOutputStream fs = new FileOutputStream (f);
DataOutputStream out = new DataOutputStream (fs);
for (int b; (b = in.read ()) != -1;)
{
out.write (b);
}
in.close();
fs.close();
out.close();
What's wrong? And, can I repair the corrupt files?

- Eclipse Plug-insI have installed Eclipse 2.0.2. In working through the tutorial I came
upon "Creating Your First Java Project." Step #5 says this:
Click the Browse button next to the Zip file field and browse to
select
<workbenchRoot>/plugins/org.eclipse.jdt.ui.examples.projects/archive/junit/junit37src.jar.
Note: This step assumes that the JDT example plug-ins have been
downloaded and installed.
The closest thing within the IDE is this:
<workbenchRoot>/plugins/org.eclipse.jdt.ui
I have looked all through the Eclipse website. I have found several
plug-ins but not this set. Can anybody point me in the right
direction?

- Reading data from a file using AntHi Everyone,
Im new to Ant and I am encountering some problems.
I have a text file which contains a value in there. I need that value
to be set into another file.
I tried using Javascript but Javascript does not support I/O for files.
Is there any command in Ant that can read a value from a text file (
eg. output.txt ) and then use that value to replace into another file (
eg. jsp ).
Thanks,

- Hiding table columns?Hi,
I'm no professional programmer, but I suppose I know enough about the
Table API to do most of the things I need. Now I'm trying to figure
out a good way to implement a functionality into my apps to toggle the
visibility of table columns.
I wonder if anyone here can provide some tips on how to handle this as
the TableColumn class doesn't seem to provide a setVisible() method.
All my tables use a TableModel, so I suspect that's where I need to do
most of the stuff. I'm thinking of setting up some kind of
two-dimensional array to hold the column names, and a visibility flag
for each column. In the TableModel methods I could then use that flag
to determine what columns and data should be processed.
Any help is much appreciated.

- JDK 1.5.0_05 won't load applets from the Internet?I'm setting up a new PC with a brand-new installation of Windows XP and
Fedora Core 3 (each with all the latest updates).
I'm having trouble with the Java plug-in: it won't load any applets
from the Internet (from the local filesystem works fine). I'm behind a
SOCKS v4 proxy; the browsers and DNS are configures appropriately and
surfing the net works fine, using Mozilla and IE under Windows and
using Mozilla under Linux -- but trying to load a page with an applet
just displays the pretty coffee mug image where the applet should be,
and when I try to leave the page, the browser hangs, presumably because
the JVM is stuck trying to download the applet.
I tried reconfiguring the gateway to use plain NAT, so I could take the
proxy out of the picture, but this did not fix things.
I never had problems like these with JDK 1.4.2.*, but with 1.5.0_05, I
just can't get it to work at all. Web Start doesn't work either -- just
sits there "checking for latest version" indefinitely.
I have Java configured to use the browser's settings; configuring the
proxy settings manually makes no difference. (Of course when I use NAT
on the gateway, there is no proxy involved at all, but that does not
work either.)
N.B. The applets themselves do not appear to be the problem -- I tried
some really simple ones, including samples from the Java Tutorial;
nothing even gets pulled across the network.
I'm hoping someone can shed some light on this -- I'm stumped!
Thanks,

- ANNOUNCE: Ice 2.0 releasedHi,
we've just released Ice 2.0 with quite a lot of new features:
- new language mappings for Visual Basic and Python
- a new light-weight and super-efficient firewall
- a streaming API that allows you to control the encoding and decoding of
objects in arbitrary formats (or the native Ice format)
- dynamic invocation and dispatch interfaces, so you can write generic
clients and server that do not require compile-time type knowledge
- new chapters in the documentation for the new features
- numerous other improvements and bug fixes
See http://www.zeroc.com/vbulletin/showthread.php?s=&threadid=987
for more info.
Cheers,
Michi.

- Protected inner classes and inheritanceApologies if I am missing something obvious, but here's the situation. I have
a top-level class with a protected inner class. I have a second-level class
in a different package that extends the top-level class. For example:
package somePackage;
public class TopLevel
{
protected class Inner
{
protected int intField = 0;
protected Inner()
{
// constructor
}
protected void innerMethod()
{
return;
}
}
}
package somePackage.otherPackage;
import somePackage.TopLevel;
import somePackage.TopLevel.Inner;
public class SecondLevel extends TopLevel
{
public SecondLevel()
{
// constructor
}
public void someMethod()
{
Inner inner = new Inner();
inner.intField = 1;
inner.innerMethod();
}
}
When I compile the second class, I get at least 4 errors:
The type somePackage.TopLevel.Inner is not visible
The constructor TopLevel.Inner() is not visible
The field TopLevel.Inner.intField is not visible
The method innerMethod() from the type TopLevel.Inner is not visible
I thought I read the Java docuementation clearly when is says
"The protected modifier specifies that the member can only be accessed within
its own package (as with package-private) and, in addition, by a subclass of
its class in another package."
and
"You can use the same modifiers for inner classes that you use for other
members of the outer class. For example, you can use the access specifiers --
private, public, and protected -- to restrict access to inner classes, just as
you do to other class members."
If I simply make TopLevel.Inner a public class, the errors go away. But I
don't really want to do that... Anything obvious??
thanks

- Anonymous inner Classes accessing final variables?Hi
When a write an inner class inside a method , it can access the
variables in the enclosing method if and only if they are final ...
Why is the compiler enforcing this ??
What might be the reason for java doing this ?? Is it that these Local
Variables will be cached for Inner class usage ??
Thanks a lot in advance!

- type Map does not take parameters ?Hi all,
I got a strange error message from the java 1.5.0 compiler:
"type Map does not take parameters" which Map certainly does.
The complete code was this mini class:
import java.util.*;
class AAA {
public static void main(String[] args) {
Map<Integer, String> map = new HashMap<Integer,String>();
System.out.println(map);
}
}
NB, it does not compile with the original compiler, but compiles happily
within an Eclipse 3.1 environment.
And it does also compile with the original compiler when I change the
reference type from Map to HashMap.
How can this be?
Yours,
Bu.
