- Graphics2D and setScale problemHello,
I have a question about using setScale to scale a Graphics2D context. I was
designing an icon editor and I wanted to show a blown up verion of the icon
with grid and all, so I used setScale(), which works, except that when I
draw lines or circles or ovals, any sort of shape that isn't a rectangle,
the lines cut through the pixel locations, almost as if it's doing some kind
of anti-aliasing, but it's not doing any such thing. So I found that I had
to write my own drawLine function, which works, but now all my shapes,
except rectangle, have to use this. Is there another way other than using
setScale() to blow up an area so that I can maipulate the pixels directly
using the build-in drawing methods?

- log4j JDBC loggingI have a various different packages within this web application that I
am writing and I am attempting to set up log4j to log directly to a
database. So each class is calling just a generic logger:
Logger.getLogger("generic");
and I have the PropertyConfigurator read in some properties from a log
file that define the database connection, the user, pass, ...
The logging to the database works, but it does not log every statement
it comes across. I have defined numerous logger.debug() statements
throughout the code and the first 6 statements throughout various
classes will be logged, but other logging statements will not.
So I set up just a stupid Logger that logs to a file on the system and
placed log statements after each log4j statement that I have in each
class. The stupid logger will successfully log all of the statements,
but the log4j statements stop logging after a bit.
Why would this be? Are statements getting lost because I am
connecting to the database? The database is on the local machine so I
couldn't imagine that being the case...does anyone have any ideas?
Thanks for your thoughts...

- Validating XML using the Xerces DOM parserI have a web app that reads an XML file uploaded by a user, parses it
and adds the information inside it to a database.
To make sure that the users aren't putting invalid data into the
database, I thought the easiest way to do this would be to write an
XML schema to validate it.
I want all documents uploaded to be validated by this particular
schema. I'm only interested in processing documents that conform to
this schema. I want the parsing to fail for any other file.
I've checked my XML file and my schema by validating them using XML
Spy. XML Spy has no problems applying the schema to the xml file and
picking up any deliberate errors that I put into the file.
I'm using the Xerces DOM parser (version 2.6.2) to read the XML. When
I run the code with valid XML, it works fine, but if I include errors
in the XML file it doesn't pick them up.
DOMParser parser = new DOMParser();
parser.setFeature("http://xml.org/sax/features/namespaces", false);
parser.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",
"http://localhost:8080/assetDB/schema/assetList.xsd");
Parser.setFeature("http://apache.org/xml/features/validation/schema-full-checking",
true);
parser.parse(xmlSource);
parser.setErrorHandler(this);
Document assetDoc = parser.getDocument();
What I really want to do is this:
get XML file
Validate xml file
If valid
process file
else
give helpful error messages
end if
Am I even going about this the right way?
I appreciate any help (or even pointers to good java/xml resources)

- API Design QuestionHi,
I'm designing an API of container objects such that:
there is an abstract ContainerObject,
ContainerObjectA extends ContainerObject, and stores:
ContainerObjectB, which extends ContainerObject, and stores:
ContainerObjectC, which extends ContainerObject, and stores:
ContainerObjectD, which also extends ContainerObject.
However, I wish to make ContainerObjectD an abstract class that must be
extended by the API user to allow for customization of the final level of
containment. This may seem a little odd, but the data is organized in
such a way that the upper levels of containment objects will be identical,
but the lower objects will differ (i.e. ContainerObjectD will contain
one or more customizable objects). So, my question is, how do I handle
ContainerObjectC? - it will only ever access the interfaces in
ContainerObjectD defined by the abstract ContainerObject, not any of the
extended elements. But, I won't know what the name or location of the
extended object of ContainerObjectD will be. Do I just leave it to the
API user to edit ContainerObjectC and insert the name of the new extended
class, or is there a way to approach this is a more structured manner?
Also, can an abstract class be extended by an abstract class? Should I
use an interface instead? That will still leave the problem of how I
should refer to the abstract class within a non-abstract one. I hope this
makes sense, and thanks for any advice!
Best Regards,

- GUI testing - open source toolsHi,
sorry if this has already been discussed.
I've been attempting to automatize a test sequence using the
following tools: Abbot and Marathon. However, Abbot happens to crash the
VM up to JDK 1.5.0_09 and Marathon runs unbelievably slowly (to the
extent that it's useless).
I wonder if there are any other GUI open source (!) tools, not listed
at http://en.wikipedia.org/wiki/GUI_Testing#Java_Test_Tools, allowing
record and replay.
What tools do you use?

- How to get file name from URL objectHi,
I am trying to save web pages to file but sometimes the URL doesn't
have the file name with it as www.google.com doesn't for example. In
this case I don't know how to get the file name of the web page since
it is not specified. If there is way to use the URL class or other
classes to get the URL to look like so http://www.google.com/index.html
then my problem would be solved.
Is there anyone here who can help me,
Thanks,

- Swing Alignment ProblemsI have had this problem a number of times, and I've always had to hack
around to fix it, and I'm not sure what is actually going on. Due to work
agreements, I don't have code I can show at the moment, but I've seen this
so often I'm hoping it's not unique to me.
I have a JPanel, and within that, a JLabel, and within that, of course,
text.
I've set the layout for the panel like this:
JPanel myPanel = new JPanel();
myLayout = new BoxLayout(myPanel, BoxLayout.Y_AXIS);
myPanel.setLayout(myLayout);
Then I have 3 or 4 or more JLabels, each set up like this:
JLabel myLabel = new JLabel("Here is my text.");
myLabel.setAlignmentX(JLabel.LEADING); //Sometimes try LEFT instead
myLabel.setHorizontalAlignment(JLabel.LEADING); //Sometimes LEFT
And I still end up with all my labels aligned to the RIGHT. (Remember, I've
tried LEFT instead of LEADING in all cases!)
I've had this happen many times. I even set the alignment on myPanel to
LEFT. I simply cannot figure it. I've set the alignment on the panel, and
on every element in the panel and on the text in every element (using both
setHorizongalAlignment and setHorizontalTextPosition(JLabel.LEADING)) and
it STILL aligns things to the right.
I've had this happen on a number of Swing panels and windows. I've heard
people comment, at times, that Swing can do screwy things like that, but
I'm not sure if they were serious or just frustrated at the time.
So does this happen for a reason? Is there something else I should align
that I haven't mentioned?
Thanks!

Ack, I was hoping I was wrong. And I was, although only slightly so:
"The fix, then, is for us to take advantage of the disk cache to make
sure that the memory pages on disk that we must read at startup have
already been loaded before we need them. How do we do this? We cannot
magically pre-load the pages just prioir to launching; unfortunately,
the VM currently lacks the ability to see into the future to detect
when the user will be launching Java (we would love to have this
feature in the future, but it is not yet present). But we can
pre-load at some earlier time, such as Windows boot or login
time. And we can keep the pages warm in the disk cache as machine and
memory conditions allow."
From <URL:http://weblogs.java.net/blog/chet/archive/2007/05/consumer_jre_le.html#Quickstarter>
They do load everything into memory, only cache memory instead of
program memory. And they then keep hitting the pages to ensure that
no cache algorithm gets to do its job.
That's just being egoistical. I bet every application wants to be
loaded from RAM. Well, at least I get to turn it off.

- How do I get the paint Rectangle in paintComponent()Help! I have been stuck on this problem for hours.
How do I get the Rectangle of the original repaint() call
in a components paintComponent(Graphics graphics) method?
For example. Say a repaint(0, 0, 10, 10) is called somewhere
in the code.
Say my JComponent has a bounds of Rectangle(9, 9, 5, 5)
In the components paintComponent(Graphics graphics) method
I can call:
graphics.getClipBounds() and that will return (0, 0, 1, 1)
Basically it returns the intersection of the original repaint rectangle (0,
0, 10, 10)
and my bounds (9, 9, 5, 5) relative to my components coordinates, which
gives 0, 0, 1 1.
But I want a way to get the 0,0,10,10 rectangle from the paintComponent
method. Is there a way to do this?
Thanks,
Bill

java-programmer, Date and Time conversion
I have an Integer variable which contains date in YYYYMMDD format. I want to
convert it first to a Date variable and then to a String variable with
format MM/DD/YYYY. How can I do that?
I also have an Integer which contain time in HHMMSS format. I want to
convert it to a String variable with format HH:MM:SS. How can I do that?

java-programmer >> Date and Time conversion
One thing I would suggest for the first one (I assume you mean it's
stored in an int variable), I would convert it to a String, and then
left pad with 0s to make sure you have four numbers at the beginning.
Then the year would be substring(0,4), then month would be
substring(4,6), and the day would be substring(6).
If the second form is stored in an int, you could do somethind like
seconds = time % 100
time = time/100
minutes = time % 100
hour = time/100
Then you could concatenate them
hour + ":" + minute + ":" + seconds

- 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?

Steffen

- 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.

- 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!

- 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?

- 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!!!
----------------------------------------------------------------------------------------------------
I use Netbean 6.1,Glassfish.Ejb3
import javax.ejb.Stateless;
1.
@Stateless(mappedName="T")
public class vectorBean implements vectorRemote {
//Vector v;
//@PostConstruct
//public void Init(){v=new Vector}
public Vector test(){
Vector v=new Vector();
v.add(new a("alex",14));
return v; }
}
2. a is a simple class
public class a {
public String m;
public int n;
public a(String m, int n) {
this.m = m;
this.n = n;
}
getter,and setters!
}
3.Jsp
InitialContext ctx=new InitialContext();
//ShoppingCartRemote
s=(ShoppingCartRemote)ctx.lookup("shopcart");
vectorRemote s=(vectorRemote)ctx.lookup("T");
Vector v=s.test();
Enumeration e=v.elements();
while(e.hasMoreElements()){
a p=(a)e.nextElement();
out.println(p.m);
}

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?
-- Sebastian
