- Sun's WTK2.5 is asking for permission to contact network every timeI've just started using the final release of Sun's wireless toolkit
(WTK) 2.5. It's asking for permission to contact the network each and
every time network access happens - I'd like to switch it to asking only
once times (or never, if possible), but can't find the option in the
docs or via the tools in WTK2.5/bin. Can anyone shed any light on this?
thanks,

- SSL HostnameVerifierWas getting "hostname wrong" when connecting via HttpsURLConnection.
Setup my own HostnameVerifier, returned true, and problem went away.
However, exactly what problem did I solve, and did I introduce a
security risk? When the substitute HostnameVerifier was called, first
argument "String urlHostName" was identical to second argument
"SSLSession session.getPeerHost()", i.e., the IP address of the server
from whom the certificate was obtained. What mismatch triggered the
call to the substitute HostnameVerifier?
Thanks.

- Strange problem!!(it is, atleast to me!!)Although, this is not a programming or development problem instead its
an end user problem which im facing and thought programmers /
developers could help.
I have Win XP SP2, JRE 1.5 installed with IE. Now for certain sites my
applets dont refresh after i click them (well ofcourse i click where a
click is expected :) this happens when i connect using my cable
broadband connection.
(I am connected to a local provider via LAN who provides me connection
to the primary ISP). On the other hand evrything works as expected
when i use dial up connection(using the phone line). Ive tried with
many browsers and it doesn work. Ive tried everything i could. And the
same site works well at my frnds place who has the same broadband ISP
but hes on a different LAN and rest all settings are the same.
The error i see on the console- " java.lang.NullpointerException Could
not send message".
I know the error wouldn be of much use but hope the explanation of the
problem may have some solutions.
Kindly help me.

- encoding troublesHi all!
I have a byte array of data which I want to post to an php script. So I send
the representing string of the byte array using a post with utf-8 encoding.
I figured java works with UTF-16BE internally, but after receiving the utf-8
encoded post in php and converting it to back to UTF-16BE it was not the
same...
I wrote a little test and it turns out if i conver a byte array to utf-8 and
back it wont match the original byte array, but the string representing it
is the same:
String test="some test";
byte[] dest,temp;
dest = test.getBytes();
try {
temp=new String(dest).getBytes("UTF-8");
}catch(Exception e) { System.out.println(e); }
try {
test=new String(temp,"UTF-8");
System.out.println(test);
dest=test.getBytes();
} catch(Exception e) { System.out.println(e); }
if(dest==temp) System.out.println("Success!");
else System.out.println("failed");
How can I convert the UTF-8 bytes back to the original byte array? And will
this work when posting to php? Its important the binary data remains intact
instead of the string representation...
Thanks in advance,
Matthijs

- inner classes and static membersCan somebody please tell me a practical reason why you couldn't have
static members (not constants) within an inner class? I know that this
is forbidden, but I haven't found a practical, concrete reason for
this... I was wondering if this was just a whimsical decision from the
designers of the language.
Thanks a lot in advance...

java-programmer, Browser shuts down....
I am having some problems with sites that have certain Java features. At
some web sites I get a grey box with an X... other web sites the browser
shuts down and goes away completely. It also puts a Notepad text doc. on my
desk top every time the browser disappears. (copy of this is below)
I have done everything I can think of to resove this situation... MS JVM and
also Sun.... Uninstal - install.... I have almost given up. It is sad that I
can only access half of the internet. I have gone to the web sites listed in
this forum that checks Java. Some say I am Java enabled, some have the greay
box and others shut my browser down.
I am running XP and IE 6.0.2800.1106xpsp2.030422-1633
An example of a web site that shuts down my browser is here. This is just
the web site to our local news program. www.katu.com
I have been to the brink of frustration and back again more times than I can
count trying to troubleshoot this situation.

- Displaying SIGNED SHORT images in Java,Hello,
Given an array of SINGED shorts gray values, how can I create a corresponding
BufferedImage. In the java docs I only see support for unsigned short? I don't
even see support for creating a BufferedImage from (int) gray level data?
Any help or pointers would be greatly appreciated.
Thanks,

- WMA compatible handsetsHello,
does anyone have an idea where I can get a complete list of handsets
that support WMA 1.0 and 1.1.
I had a look at:
http://developers.sun.com/techtopics/mobility/device/pub/device/ but it
look quite outdated.
Also if the handset support wma - does it mean the j2me app will be
able to send sms messages?
Thanks in advance,

- Sams Teach Yourself Java 6 in 21 Days - Installation ErrorHi,
I have just bought the book Sams "Teach Yourself Java 6 in 21 Days",
and am getting an error installing the JDK supplied with the book.
After running "start.exe", I select the AMD 64 installation package.
After the InstallShield package loads up, I get an error, "This
installation package is not supported by this processor type. Contact
your product vendor.".
The installation then aborts and I cannot get any further.
I have an HP PC with AMD Athlon 64 X2 processor, running Windows
Vista.
Has anyone installed the software successfully on a similar platform,
or knows what might be wrong?
Thanks in advance for any help.

- Hooking up jdbc to a local access databaseThe driver I am using, the default jdbc/odbc driver, in netbeans is
not working for connecting to an access db on my hard drive. The

up I get a "unable to obtain schema" warning. then on the icon for
the database after im connected in netbeans, the link to the tables is
broken. Thanks

- Absolute layout manager dimensionsHi again.
Is there any way to create a layout manager consisting of two cols where
the left has a width of 100px and the right one uses the rest of the
space available?
Something like HTML's <frameset cols="100,*"....>

- Why isn't new used in the following.In the following:
public class toupper {
private static void upper(){
String a = "chad";
System.out.println("Upper Case is:" + a.toUpperCase());
}
public static void main (String[] args) {
upper();
}
}
Why isn't the line
String a = new String();
Necessary? I thought this line might be omitted because for whatever
reasons I was thinking toUpperCase() was a static method. It isn't.
Because when I change the line:
System.out.println("Upper Case is:" + a.toUpperCase());
to
System.out.println("Upper Case is:" + String.toUpperCase());
I get the following:
$javac toupper.java
toupper.java:6: non-static method toUpperCase() cannot be referenced
from a static context
System.out.println("Upper Case is:" + String.toUpperCase());

- Tiers, Layers, Models and Design Patterns (Model-2 of Struts)Hi,
I'm busy investigating the Implementation View of the 4+1 architectural
views of RUP.
I'm getting a bit confused about the difference between Tiers and Layers and
how to
get my business logic model + struts into it. I would like to invite you to
join a discssion
of what is actually meant by layers and tiers, how they relate to eachother
and how
for example struts, consisting of a servlet controller, an action, a form,
and a JSP view,
is "resting" on the layers and partitioned over the tiers. Besides that
assuming that the
system in integrating via XML to a back-end system I wonder how this in
reflected in
tiers and layers.
The tiers I'm thinking of are:
- Presentation (= on the browser)
- Web (= JSP and servlets on the server)
- Business Logic (=EJBs on the server)
- Enterprise Information System (=system to integrate with)
- Database (=back-end database)
Hope this is not enough to discuss in one thread and that the problem I have
is clear.
Kind regards,
Jan

- Design qq... is it better to have a program with, say, 10 methods
and then call each 10 from the mainline OR have the mainline call
the first which calls the second which calls ... the second

- JSP NTLM extraction of windows usernameI found this username extraction code on "Real's How to..." site. The code
work great, but I
need help with getting it to work in my jsp/servlet
What I have done is put this code into a jsp of my own. the jsp has a form
on it. this form gets submitted to a java servlet, but the parameters
(fields from the form) are all null. If I remove the NTLM username
extraction code from the jsp, the jsp works perfectly.
I am not sure how this java scriptlet is interfering with the field values
of my form submission.
I use the hidden field 'action' to determine what happens in the servlet...,
but when i get the parameter in the servlet, its value is null, despite
having the JavaScript set it just before
submitting.
Any help or insight would be greatly appreciated!

- NetBeans IDE 3.5 does not runHi all,
I've installed NetBeans IDE 3.5 on Windows XP. But if I try to start it,
a message box shows "cannot load jvm.dll". This library does exist in
a subdirectory. My questions are:
1) Is NetBeans IDE 3.5 a stand-alone software, i.e. can it run without
other software, or should a java SDK be installed?
2) If NetBeans can run without java SDK, maybe one must set the path for
jvm.dll. How can it be done?
Many thanks!

- Java facade to Ada code?Hi. My team has a bunch of legacy Ada code. Our new code is being
written in Java. However, we still have many complex algorithms
written in thousands of lines of Ada. Rather than rewriting the
tested/validated Ada code in Java, we'd like to create a Java facade
that would delegate to the Ada code, thereby making the Ada code
available to newer Java client objects. Is this reasonable (as opposed
to rewriting everything in Java)? Anyone know what
mechanisms/libraries would support such an approach?
Thanks!

- login username from databaseHi,
I have a login window with a username and password fields. The
program checks the username and password from a mysql DB table. If I
enter a username that is not in the database, how do I get it to
display a message that the username does not exist.
Thanks

- Is Set faster than ListHello everyone,
is Set faster than List for most of the operations? I implemented
prime number Generation by "Sieve of Eratosthenes" algorithm. One
method uses List other Set. After Benchmarking both the algorithms, I
find that List are faster than Set for if the number of elements to be
generated is small. But for larger it is Set that is significantly
faster than List.
Is this due to, how Set and List are implemented? and is it a general
rule to use Set over List where element repetition is not significant?
Why benchmarking in Eclipse are slower as compared to console(while
running the benchmark in console, I keep eclipse open, and vice
versa)? I presume that foreign process that could effect the benchmark
in both the cases remain the same.
Thanks
