- Bug in java.net.Socket close() behavior?According to the API for java.net.Socket close():
"Any thread currently blocked in an I/O operation upon this socket
will throw a SocketException."
http://java.sun.com/j2se/1.5.0/docs/api/java/net/Socket.html#close()
I have observed that java 1.5 on FreeBSD does not follow this while
the Windows and Linux ones I have tested do. On the FreeBSD runtimes
that I have tested, a thread blocked on reading a socket just hangs
forever if the socket is closed.
Attached is a simple program that tests this behavior. It just
connects to a port on one of my servers and has a reader thread
watching input from the socket and closes the socket in a different
thread to see if the reader thread gets an exception.
Java runtimes that I have tested this on:
# java -version
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build diablo-1.5.0-b01)
Java HotSpot(TM) 64-Bit Server VM (build diablo-1.5.0_07-b01, mixed mode)
# java -version
java version "1.5.0-p2"
Java(TM) 2 Runtime Environment, Standard Edition (build
1.5.0-p2-root_07_mar_2006_02_41)

The link has gone stale. The site itself still exists. Last time I

I spent 20 minutes unsuccessfully last night trying to find a new

- Generics and returning specific subclass from methodI have an abstract class called say Base and two subclasses, say Sub1 and
Sub2. Let me define a method in Super which I want to return a new instance
of the superclass itself but I want to access this without having to cast.
IE,
public class Super {
public <E extends Super> E partialCopy() {
return this; // return this for example
}
}
public class Sub1 extends Super { }
Then I want to do this without the cast.
Sub1 s1 = new Sub1();
Sub2 s2 = s1.partialCopy();
Can I do this with generics ?

- Exec() Help!Hi,
I'm trying to start an external applet from an applet I'm writing. I know
Exec() Is the key, but I don't know how to use it. I know how to execute
external native programs (I.e. programs I have written in BASIC and
compiled). But starting an applet from an applet totally throws me. I have
tried searching the net, and that has a lot to say about executing shell
scripts, and natives - which I know how to do.
What classes do I need to import? what line of code invokes an external
applet? I don't need to grab output from the applet I want to execute, or
send input. I just want it to run.
Pleeeeeeez can anyone help, my project has to be handed in soon :-(
Thanks,
Dafydd.

- Toward a generic Disk Sort for JavaI was thinking how you might go about writing a sort that could handle
more data than could fit in RAM. It handled the problem is Abundance
by checkpointing the app to disk to free up maximum RAM, then spawning
a copy of Opt-Tech sort. My records were roughly like DataOutputStream
would produce, so I could automatically generate the command script
sort the fields in any way I wanted.
I thought you might pull it off in Java this way.
1. You write a comparator as if you were going to sort Objects in an
ArrayList.
2. the external sort has an add method that also takes collections.
It accepts a "chunk" of records, and sorts them using Sun's sort.
Then it writes them out as SERIALISED objects in heavily buffered
stream. There may be some way to do a partial reset after each object
to speed it up.
Then you repeat collecting, sorting and writing another batch to
another file.
When you have created N files, you recycle, appending. (Optimal N to
be determined by experiment). Ideally each file would be on a
different physical drive.
Then when all the records have been added, you start merging chunks
into longer chunks, and writing out the longer chunks. Each N-way
merge cuts the number of chunks by 1/N and increases the length of the
chunks N times.
on the final merge pass does not happen until the user invokes the
Iterator to hand over the resulting records.
Another way it might be done is the records to be sorted must by byte
arrays, chunks effectively produced by DataOutputStream. You specify
offset, length and key type e.g.
int, byte, short, float, double, String.
This would require a detailed knowledge of the bit structure of the
records, the way you did in the olden days of assembler and C.
This would be clumsier to use, but would avoid the overhead of
pickling and reconstituting records on every pass.
Then of course, there is the possibility someone has already solved
this and done it well.
The universe has a sneaky habit. Problems start out small, and it
looks like a purely in RAM solution is perfectly adequate. Then they
bit by bit grow and grow and start pushing the limits of the RAM
solution. Suddenly you are faced with a major redesign.

- [J2ME] UI /freezes/ after IOExceptionHi,
I have a MiDlet that starts a Thread through a Runnable, in which
there is IO activity:
Runnable runner = new Runnable() { // some IO stuff there };
Thread thd = new Thread(runner);
thd.start();
The application runs well, until I need to close the IO channels that
are opened in that separate Thread.
Of course, I catch the IOException in my Thread, and the Thread
completes properly (and dies...).
But after this catch, the UI is not responding: if I press a button the
menu will not show, and if I do some programmaticaly changes in the UI
it does not display and the call blocks (i.e. if I add an item in the
current screen, nothing happens and the next line --System.out.println--
doesn't execute).
I know the application didn't die, cause I have another Thread running a
'while' loop and printing "I am alive!" even when the UI freezes.
And also if I don't perform UI changes I can print stuff in the main Thread.
Any idea to help me ? Thank you.

- JRE installation woesHi All
I have installed the latest version of Sun's JRE on my Windows XP Pro PC.
However, its "performance" is somewhere between abysmally slow and not at
all. If I e.g. open the Java Control Panel module and click on one of the
tabs, it takes over two minutes for that tab to display - this on a 3.4 GHz
dual-processor 4 GB memory PC. Java aplications run no better. It does seem
to "speed up" if I Alt-tab to another program and then Alt-tab back.
CPU load is negligible so clearly, the JRE is waiting for something that
occurs only rarely. But I have no idea where to look.
Any help will be very much appreciated.

java-programmer, Expanding on Video Formats
I'm wondering if somebody with java knowledge will be able answer my
question.
Would it be within the realms of possibility to create a web-based
video editing suite? (Which media format -- Windows, Quicktime, etc. --
might best lend itself to such a task?)
Also, I imagine that this application may require a desaturation
process to bring down the memory size for the raw footage.
I don't know enough about java programming to even guess about this;
but with the current prevalence of digital editing software, an online
version has convenience written all over it.
Thanks,

Short and simple answer: no. And the answer has nothing to do with
Java, the amounts of data are simply WAY too high.

Very unlikely, since video resolutions (i.e. data volume) is going
to grow as well, not just network bandwidth.
Besides, I really don't see the advantage.

It could be useful to assist in an online edit job without actually
having a program yourself.
Still, if you need to work with large numbers of takes, it might help
to have footage in a lower sized format.

- Eclipse doesn't behave like built-in help says...Hi,
I'm a Java command line programmer.
I started step-by-step with the tutorial in the built-in help, Europa
release.
>From the Content view:
Workbench User Guide ->Getting started -> Basic Tutorial -> Task and
markers -> Associated Task.
All goes fine until point 7.
It says:
[...]
5. After the new task has been added, click in the editor on the first
line or any other line above the line with which the new task is
associated.
6. Add several lines of text to the file at this point.
7. Notice that as lines of text are added above it, the task marker
moves down in the marker bar in order to remain with the associated
line in the file. The line number in the Tasks view is updated when
the file is saved.
[...]
Actually task marker in the marker bar disappeared, and the line
number in the task view never update...
Now I'm thinking what will happen with brakpoints or something else in
debugging...

No - this optimization cannot be done statically for runtimes that
support dynamic code loading, as the CLR and JVM do. If the compiler
tries to replace 'callvirt' with 'call', the assembly will no longer be
verifiable, and if the assembly is dynamically loaded into the context
of another application, the virtual call semantics will be violated.
For example:
---8<---
using System;
public class B
{
public virtual void M()
{
Console.WriteLine("Hello from B");
}
}
public class App
{
static void Main()
{
CallM(new B());
}
public static void CallM(B instance)
{
instance.M();
}
}
--->8---
Compile this App.cs to App.exe, then disassemble with:
ildasm App.exe /out:App.il
Then edit App.il so that CallM is written thusly, applying the
"optimization":
---8<---
.method public hidebysig static void CallM(class B 'instance') cil
managed
{
// Code size 9 (0x9)
.maxstack 8
IL_0000: nop
IL_0001: ldarg.0
IL_0002: call instance void B::M()
// (above was 'callvirt')
IL_0007: nop
IL_0008: ret
} // end of method App::CallM
--->8---
Assemble with:
ilasm App.il
Verify with:
peverify App.exe
Observe error:
---8<---
Microsoft (R) .NET Framework PE Verifier. Version 3.5.21022.8
Copyright (c) Microsoft Corporation. All rights reserved.
[IL]: Error: [c:\proj\cli-callvirt\App.exe : App::CallM][offset
0x00000002] The 'this' parameter to the call must be the calling
method's 'this' parameter.
1 Error Verifying App.exe
--->8---
For a concrete example of virtual method call semantic violation,
consider a second application, App2.cs:
---8<---
using System;
public class D : B
{
public override void M()
{
Console.WriteLine("Hello from D!");
}
}
class App2
{
static void Main()
{
App.CallM(new D());
}
}
--->8---
Compile this with:
csc App2.cs /r:App.exe
Run App2.exe when App.exe is the version assembled from App.il modified
to use call instead of callvirt, and observe:
---8<---
Hello from B
--->8---
Recompile the original App.cs from source, then run App2, and observe:
---8<---
Hello from D!
--->8---
- the "obvious optimization" has broken virtual method call semantics.
Implementing the "optimization" for strictly private classes is not
useful either, as reflection with appropriate permissions, along with
runtime code generation, can see through such visibility constraints.

- Show a bean property in jsf....it's so difficult?????Hi....
i'm a simple problem but i don't found a working solution....
I have a jsf application and i have to show a bean value into a jsp
page.
I show you my passes...please correct me where i go wrong,,,
For the first i declare property in backing bean
private String[] arraylinee;
In my application an user clicks a button, the application calls bean's
method and creates this array of string,that's what i want to show in
my jsp page.
I've developed in my backing bean getter and setter methods..
public String[] getarraylinee(){
return arraylinee;
}
public void setarraylinee(String[] arraylinee){
this.arraylinee=arraylinee;
}
1a Question)
It's not needed that bean return property?
That is...my bean's method is
public String retrieveblob()throws
IOException,SQLException,NullPointerException{
Database2 db2 = new Database2("nomeDB","root","shevagol");
if (db2.connetti())
k=1;

even if its just for testing. and does anyone know if its difficult/time
consumeing to sign applets?
Thanking you niall

- Apache Axis, XML document, errors aboundI just wrote a simple java program that uses a web service call from
the internet, and attempts to save it to a file.
I have run a very similar program (actually used the same code) from a
different machine, and it worked fine, though for somereason running it
now is giving me errors. I have never seen this type of message
before, so I am a bit confused.
Here is the error:<error>
Exception in thread "main" AxisFault
faultCode:
{http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode:
faultString: org.xml.sax.SAXParseException: Content is not allowed in
prolog.
faultActor:
faultNode:
faultDetail:
{http://xml.apache.org/axis/}stackTrace:
org.xml.sax.SAXParseException:
Content is not allowed in prolog.
</error>
I use this almost exact same code in another program that is running on
a web server that is running fine right now, so am not sure what to do.
I have all the axis libraries and the xerces libraries in my jre ext's
folder. Below I will include the pertinent code:
I assume this is an error from axis and not from the code that I am
running, but am lost.
**Assume this is the only code used. I use other code, but it is
provided in the packages. Any suggestions?
<code>
String xmlFile;
// Needed for the web service with NOAA
WeatherParametersType typeArray;
typeArray = new WeatherParametersType();
typeArray.setMaxt(true); //works
typeArray.setMint(true); //works
typeArray.setPop12(true);
typeArray.setWspd(true);
typeArray.setWx(true); //works
typeArray.setIcons(true);
String[] argst={"here","there"};
//I assume this constructor has no bearing on anything
Options opts=new Options(argst);
NdfdXML ndfd = new NdfdXMLLocator();
opts.setDefaultURL(ndfd.getndfdXMLPortAddress());
URL serviceURL = new URL(opts.getURL());
NdfdXMLPortType info = null;
if(serviceURL!=null)
{
info = ndfd.getndfdXMLPort(serviceURL);
}
Calendar now = new GregorianCalendar();
now.add(Calendar.DAY_OF_YEAR,0);
Calendar next = new GregorianCalendar();
next.add(Calendar.DAY_OF_YEAR,+7);
//<latitude>38.84N</latitude>
//<longitude>077.03W</longitude> is for zip 20001
BigDecimal lat = new BigDecimal(38.84);
BigDecimal lon = new BigDecimal(77.03);
info.NDFDgen(lat,lon,(ProductType.value1),(now),(next),(typeArray));
</code>
I know this probably seems vague, so I will add any other code or help
needed. Thanks for the help.

- J2ME Server on a PCI have a question about J2ME using bluetooth. I am trying to implement
a client server applicatin between my phone (Nokia 6630) and my PC. I
can send data over bluetooth to the PC on a virtual serial port but I
need a way to "catch" the data I sent on the PC end and turn it back
into an image. Are there any applications out there that do this
already? Can I run a J2ME server on my PC? Thanks
