DateFormat df = new SimpleDateFormat("HH");
TimeZone tz = TimeZone.getTimeZone("GMT");
tz.setRawOffset(cal.getTimeZone().getRawOffset());
df.setTimeZone(tz);
System.out.println(df.format(cal.getTime()));

- [Struts] Composite actions using include?Hi,
I have a Struts 1.1 based webapp. A new requirement has come
up, which I can satisfy by executing the existing actions A, B, C
and forwarding to a new page xyz.jsp. The idea would be to
write an action X and from there include (not forward) the
existing actions, do some additional magic, and finally return
an ActionForward poiting to xyz.jsp.
How can I define an ActionMapping that allows me to do that?
Or must I hardcode includes to A, B, C in X using
RequestDispatcher.include()?
Is this even feasible?
What are the alternatives? Perhaps I could define A', B', C' in my
struts-config, such that A' forwards to B' forwards to C' forwards to xyz.
(But this would require changing existing code, too, because there would
be no place for X's extra magic).
Any thoughts?

- Passing by reference, more confusion...I have an object that's passed in to a function as a parameter i.e public
boolean getProjectTitle(ProjectHeader_DTO obj) {...}
If I then call a method on this object inside the function i.e
obj.setTitle("test") then using obj.getTitle() from outside the function it
displays the property set correctly!
But doing something like this inside the function doesn't -
ProjectHeader_DTO x = new ProjectHeader_DTO();
x.setProjectTitle("test");
obj=x;
As long as I explictly set the properties it works but why not when
assigning another object?
Tried using the clone() method aswell & inside the function its works fine
until after the return!
I do not want the object to be return'ed from the function!
Any ideas?
thanks

- Force Reload on JSP Pages?I've noticed this odd behavior when working on my Web application, where if
a JSP page was cache-able then the servlet would never run. I guess this is
normal since the browser assumes the page doesn't change, so it doesn't put
a request in to the server.
But I'm curious. Is there some command or perhaps a server config that would
allow all JSP pages, whether cached or not, to always reload? I hope this
makes sense, if more is required, I'd be glad to explain more. Thanks for
any assistance in advance!
Emery.

- Why jsp can't get the Vector fill with user-defined class by the Remote interface?Because It is a big project so i provide a model to express my
question,
Qestion is:I want get the Vector full fill with the a Object in Jsp.
but I can't get it,There will problem will return test return,but we I
Choose String but no class a 's object ,It can be return successful.It
seems that jsp Can't recognize the class a,,but I really include the
Ejb module in jsp's lib.and editor alse prompt a's information.
I alse test it in JBoss server It alse occur Exception!
I cant understand why,
so come to here ask why?Please help me,3ks very much!!!

- HP/UX Java 1.3.1.02 date/time differencesHi!
We seem to have differences between the unix system time (coming from
an NTP server) and the time our java application has (as it produces
timestamps).
At the start of the app the time is synchro and after about 2 weeks
the time is 20secs ahead of the system time...
Does the Java VM calculates the current time by its own (i.e. counting
secs from start)? Or should it better get the time (if
System.currentTimeMillis() is called) from the host system?
Regards,
Steffen

- float to int conversionSystem.out.println(new Float(21082007.0).intValue()); // -> 21082008
System.out.println(new Double(21082007.0).intValue()); // -> 21082007
Why?
System.out.println(new BigDecimal(21082007.0F).intValue()); // ->
21082008
System.out.println(new BigDecimal(21082007.0D).intValue()); // ->
21082007
Again, why?
And what's the proper way of doing it, using always a double?
Thanks in advance

- Ant complaintHaving spent the past several hours trying to solve what ought to have
not even been a problem to begin with, I've noticed something about
Ant.
It appears that Ant as it is delivered comes with a bunch of optional
tasks that it knows about inherently, such as the Scp task.
It also appears that while Ant ships knowing what these tasks are, it
does not ship with jars they depend upon, such as jsch. The
documentation tells you to go out and get these jars on your own, and
put them in your Ant lib folder.
Here's the part I don't like. When Ant starts, it appears to try to
load optional tasks like Scp. When such tasks fail to load the first
time, due to the dependencies not being there, it is then impossible
to recreate a task with the same classname later using a taskdef
element, even if you include your own path containing all the jars it
needs.
Let me explain why this is a big issue. I work in a team. X number of
developers on my team share the same build script, on far-flung
machines.
I want to add Scp to the build script. I cannot simply manually put
the jsch jar in my own Ant lib folder. It won't work when anyone else
on my team tries it.
Instead, I need to check the jsch jar into my project along with the
ant script. Then, every developer on my team who gets the new script
will also get the jar to go with it. So far this seems fine.
The problem is that when the developer runs Ant, I still cannot
instantiate the Scp task because the jsch jar is not in the classpath
when ant starts. And, for some bizzare reason, I cannot even define a
new scp taks using a taskdef element with a classpath (the way you'd
do it if you were deploying your own task). Why this fails I don't
know. My guess is that Ant somehow keeps track by class name that the
task failed to load when Ant started, and refuses to try to load it
again.
I tried many ways to solve this problem, including copying the jsch
jar into Ant's lib folder. Nothing works because before I can do
anything Ant has already decided that Scp is an unloadable task.
This is terrible behavior. Ant should either not come with "optional"
tasks predefined that won't load, or it should at least offer the
chance to reload them with a specific classpath later.
Can anyone think of any way around this problem?

- Slashdot says Nyet to MonoNot that I particularly care anymore, especially given the very strong
push by Java in open source circles (e.g. Apache's planned J2EE
Geronimo app server and Red Hat's plan to create an open source Java),
but it seems a lot of open source advocates in slashdot seem to feel
the same way I do - Mono is a useless and doomed project that is also
rendered dangerous for Linux by the Microsoft patents hanging over it.

Hi,
Call me stupid but where can I find the messagebox in Java?? Or do I have to
create one myself? What I need is a simple function just like Alert( "I'm
annoying!" ); in JavaScript.
Greetings,
Rick

Take a look at the JOptionPane class. I have used this to display messages.

Do you mean a pop-up message?
AWT - Dialog.
Swing - JDialog, JOptionPane.

In Swing, try JOptionPane. It has static methods to do convenient and
simple messages. For AWT, unfortunately, you have to write your own.

You must use a scripting language such as javascript to do this on the
client side. You can register the script from your code behind pages...
this.Page.RegisterClientScriptBlock("ShowMessageBox","<script
language='javascript'>window.alert('This is a message
box!')</script>");
...or...
this.Page.RegisterStartupScript("ShowMessageBox","<script
language='javascript'>window.alert('This is a message
box!')</script>");
...or...
you can plant the script directly in the aspx page.
I sure there are many other options as well...

Hi!
I've created a simple ASPX form that displays a record from a SQL Server
table. I have a "Delete" button on the form. When the user clicks it,
I want to prompt the user with
a message ("Are you sure you want to delete... ?").
I realize the Yes/No Messagebox can be done via Javascript -- but how do
I retrieve the Messagebox return value in my .ASPX page?
so I can act on it (i.e., to perform the delete)?
Thanks in Advance
Mac

return confirm('Are you sure you want to delete this record?');

Hi Mac,
You can add the confirmation messagebox in aspx page as shown below.
You have to wirte the following code on the page load event , which adds an
onclick event to the asp.net button to
display a message box. When u click ok it will proceed to the delete
operation.
protected void Page_Load(object sender, EventArgs e)
{
bnDelete.Attributes.Add("onclick",
"return(confirm('Are you sure to delete?'));");
}

Well, thats a bit vague. If the user clicks no/cancel, the form isn't
POSTed to the server so nothing changes. If the users clicks yes/ok,
then the form is POSTed back.
You can then assume that if the form is POSTed then the user clicked the
yes/ok button. If the user has javascript disabled, obviously you
cannot determine this.

Here's some server side code that uses javascript to display a confirmation
message.
myDeleteButton.Attributes.Add("onclick", _
"return confirm('Are you sure you want to delete?');")
In this example, the Delete button will post back only if the person
confirms they want to delete. Otherwise the server code is never called in
response to the button click.
Here's more info:

When I run my ASP.NET app in the debugger,
System.Windows.Forms.MessageBox.Show works when running on the server.
It does not work when I actually upload my web site to the web server.
That is really annoying! I wish it would not work in the debugger!
Things should not work differently like that.
Anyway, I am looking for alternatives. I can do something like:
Response.Write("<script>alert('hello');</script>");
from the server side, but I cannot specify the title, and there is no
return value. Yes/No MessageBoxes are useful! Is there any better
option? I really would like something that can be launched from the
server side that displays some text and can post back some kind of
result. Is that possible?
BTW, I don't think that I've seen a mention of the ASP.NET faq at:
http://www.syncfusion.com/faq/aspnet/default.aspx
That really is a useful document.

- Getting HTML title using HTMLEditorKit.ParserCallbackI am parsing an HTML file using ParseDelegator and a ParserCallback. I am
trying to get the document title and the HREF links. The ParserCallback is
successfully getting the HREF, so I know it is basically working. However,
when I try to get the title, I always get back null. Here is the relevant
code of the ParserCallback subclass. Anyone have any clue as to what I'm
doing wrong?
public void handleStartTag(HTML.Tag tag,
MutableAttributeSet attrSet, int pos)
{
if (tag == HTML.Tag.TITLE)
{
urlTitle = (String)attrSet.getAttribute(HTML.Attribute.TITLE);
System.out.println("attrSet: " + attrSet); // prints ""
System.out.println("found title: " + urlTitle); // prints null
}
if (tag == HTML.Tag.A)
{
// This successfully gets the target URL
String targetURLStr =
(String)attrSet.getAttribute(HTML.Attribute.HREF);
}

- Threads not running in starting order (?)Hi!
Below I do start Thread t1 before t2. t1 tries to call print1() on a
Printer object and t1 print2() but only the first will success since it
obtains a lock on the Printer object. I'm surprised that although t1 is
started first the code prints "2". If I put a sleep(5) between the
starting of the threads t1 wins the race.
Can somebody explain?

- right click menu not highlightingIm working with a jtree and I have added the jpopupmenu to the jtree
object.
When I right click a node the menu comes up appropriately, it even
accepts clicks and performs the appropriate action. The only thing
that isnt working is the right menu highlighting when I have the mouse
over the menu items...
Im wondering if there is some place in my code where I perhaps overrode
some code that would typically be responsible for highlighting the
right click menu... I implemented a little drag and drop functionality
for the jtree, could this be messing with the highlighting of the menu?
Thanks

Presumably anyone who thinks that Rush Limbaugh is not The Voice Of God. :-)
Although in all fairness he more likely was referring
to those individuals who think, among other things, that
socialism/communism cures all ills, admires/admired Mao
Zedong and Lenin (*not* Stalin, who corrupted the notion),
and thinks that $100M/yr CEOs are obscenely overpaid.
(I've wondered, though: in a communistic economy, why would there
be any need of money at all, except for dealing with the other
countries? The existence of the ruble appeared to be a kludge;
of course now that Russia's capitalist, it's a moot point.
Not sure regarding the CEOs; I'd have to look. I wouldn't mind
$100M a year but I'm not a CEO...and I know which system works
better. If it's not obvious, look at N Korea and S Korea, and
then tell me which one's starving :-) . The weird bit is, the
US Prez only gets about *$400K*....)

- Most Java apps are flawed on my systemI'm using a couple of free Java applications that easiliy outperform free native windows application. I'm very upset that those Java application share a common set of problems on Windows due to bugs in the Java libs and the authors are not willing to investigate and work around the problems. If I were a Java programmer I would probably send some patches to the authors or at least point to some resources but unfortunately I'm not a Java programmer. The reason why I post here is I hope to find some resources like code exmples that I can forward to the authors to work around the bugs. First issue is the Java applications save their settings in the root directory of my D partition.
D:\.entagged
D:\.LimeWire
D:\.Phex
Pretty much all Java apps got this all wrong because people get very upset if applications trash their system while they are supposed to write either xcopy style (windows power users prefer unanimously xcopy apps according to a poll I made because of the ultimate simplicity and transparency) to the startup dir where the application is located or to the user context as defined in Microsoft's design guidelines which would be 'C:\Dokumente und Einstellungen\Frank\Anwendungsdaten\' on my system and would translate to 'C:\Documents and Settings\Frank\Application data\'. Please note that the windows explorer wouldn't even allow to create a dir with preceding dot manually and no Windows user would want to use a name with esoteric characters, abreviations or casing. I've summarized the technical reasons for the problem here:
http://www.gnutellaforums.com/showthread.php?s=b443bdda9ec96e6db7a54aed0858e8f9&threadid=44579
The second problem is that strings like "ain't" are saved as "ain-t" in filenames, this is unacceptable for a MP3 tagger and for any other reasonable application, on top of that there are casing problems as well. Nobody is willing to work around these bugs, it appears they stop to read my crys for help as soon as they read Windows, am very disappointed about Java, I got a couple of GTK+, QT, wxWindows and XUL apps working here on Windows starting rocket fast, looking beautifully and working amazingly well, some of 'em much better than most native apps.
It's OK when a crossplatform app is a little out of the norm, I close the application and it's all good but messing with my files, folders and system is something I find very annoying.

I understand and sympathize with what you are trying to achieve, but I
believe you are barking on the wrong tree here. Eclipse on FreeBSD has
been in a rather good shape for at least the last two years that I have
been using it:
- The IDE port gets updated a few days or weeks after the official release.
- The various milestone releases from the development version are
usually ported as well.
- Many different plugins exist in the ports tree for Eclipse.
I also believe that people do get help when posting to freebsd-java
about eclipse and I'll make sure the same thing happens on
freebsd-ports. There are some things that could be improved however, like:
- Faster response to open PRs.
- More people working on porting the platform or the plugins.
- Official support from the eclipse.org site.
The first two are not going to be improved by a new mailing list, since
a mailing list by itself does not spark new interest on a topic. I'm
afraid that they may be harmed instead, since there might not be many
(or any at all) subscribers to that list that are also ports committers.
The way things usually work in FreeBSD-land for contributors without a
commit bit, is that you submit an improvement, try to get the attention
of a committer and then work with him through any details. The committer
attention is not something you get very easily, especially if you
consider how many lists these people are usually subscribed to.
Don't get me wrong, I will subscribe if such a list is created, but I
fail to see the need for it. Check out the archives of freebsd-apache,
freebsd-rc, freebsd-python and freebsd-perl for examples on the nature
and the amount of postings I expect we will get. Do we need a new list
for such an amount of e-mails?

Apache Tomcat Web Server
MySQL database
JSP with Java for writing the web page
But unfortunately, I encountered some problems in properly linking my
JSP to the mysql database. I have installed the JDBC connector
interface already.
I would apperciate if anyone can give me some hints on the proper set
up and configuring of the architecture.
Thanks a lot.

- Regex GroupsHi,
I have a question concerning the behavior of regular expressions in Java. I
have a text: "text-123-234-535-235"
I use a regular expression to get the text: "text(-[0-9]*)*".
The problem is that I don't how many number blocks there will be. It can one
or twenty. Java only delivers me the last matched block as group. How can I
get all?
I can't use String.split because the regex is configued in a config file and
the regex can change as can the text. So the Java code needs to be flexible
what to do.
Is there any way to do this?
Thanks,
Andreas

- Short question about JSliderHi,
I have a problem with the font of JSlider labels.
This code compiles but does not work and I am wondering how I can set
the label font :
JSlider s = new JSlider(JSlider.HORIZONTAL,min,max,value);
Font f = new Font("Monaco", Font.PLAIN,9);
s.setFont(f);
...
Thanks for your help and suggestions

- Applet Canvas / Panel ProblemHello,
I have written a threaded tree control which is displayed in an
applet.
The way it works is that the reusable control is a canvas.
The control is created in an applet and the canvas is drawn onto a
panel.
Things work great when the content is static, however when the tree
structure
is changed - i.e. someone adds a folder or deletes a file problems
creep in.
I have no problem updating the tree (which is the canvas) but after
every change the new canvas needs to be placed on the panel.
I have tried
Panel.remove(tree);
Panel.add("Center", tree);
(there are three panels in total - the other two have scrollbars in
them)
But this does not appear to update when changes are made.
So I have tried
Panel.removeAll();
Panel.add("Center", tree);
Panel.add("South", horizontalScrollbar);
Panel.add("East", verticalScrollbar);
This does the update perfect however I get a flickerwhen the update
occurs.
So basically my question is in two parts?
Can anyone suggest how I can update the panel to avoid it flickering?
Or anyone suggest an alternative way of organising my tree so it
remains a generic control but has a better method of updating?
does that make sense?
Any suggestion greatfully recieved.
Regards
Lloyd

- TCP Keep Alive probesHi All,
I have a java client app and want to send TCP Keep Alive probes to my
server every 10 minutes as opposed to the default 2 hours. I see a
setKeepAlive() call in the API, but that only turns on whether you want
to send Keep Alives or not. How do i specify the Keep Alive probe
interval?
Thanks,
Grant.
