How does the JVM call Windows GDI Text functions?

I need to find out how the JVM calls Windows GDI functions for Java running on Windows. I am a programmer at an imaging software company and we "hook" to client applications to extract information for searching and indexing. Basically what we do is tell the app to refresh itself and then we intercept the text output functions to the GDI. Recently, when trying to image enable an Oracle app (Sun JVM or bastard version thereof), we failed to capture any text output. None of the documented MS GDI text output functions are being called to display that text. Does anyone with an intimate knowledge of the workings of the JVM on a Windows platform know how this is accomplished. I currently have calls pending at Sun and Microsoft, but sometimes these forums have more info than they do. Thanks in advance for any help you can provide. ([email protected])

I would venture to say that SUN is generating its own
text. That would be necessary in order to handle all
of the sizing and layout management issues which
happen in Java real time, as opposed to Windows once
at compile time.Not likely. Font rendering is always done at runtime and it would be generally unwise to do it yourself given the availability of TrueType fonts and the highly optimized rendering engines. I would be shocked if Sun tried to do it themselves.

How does the JVM recover from a java.lang.StackOverflowError?

As far as I know that whenever a java.lang.OutOfMemoryError is thrown, the application is in an unknown state and only a restart of the JVM can fix this. How about java.lang.StackOverflowError? If uncaught, the calling thread is terminated for sure, but the other threads? Are there side-effects?

In windows OS that thread will die and thats all.
I think that in some unix systems the whole process
is likely to fail.Not exactly. It's not nearly as dependent on the operating system as it is on the quality of the JVM implementation. StackOverflowErrors are tricky to handle correctly in all cases, but most JVMs (including Sun's) now properly handle the vast majority of them. FWIW, most unix-based or unix-like operating systems make it somewhat easier to deal with StackOverflowError than Windows, particularly Windows versions prior to Win2K.
A thread that triggers a StackOverflowError can actually catch it and recover; the important thing to note is that if you want to keep executing code on that thread, you have to allow many or most of the activations (i.e., function calls) on the stack to be unwound. Otherwise, you'll quickly provoke another StackOverflowError since you will still be close to the end of the stack.

How does the JVM handle private class parameters in a utility class?

If I have a class that is public and not labeled as static, but it's constructor is private so that it cannot be instantiated, and all of its parameters and methods are both private and static. The methods modify the private parameters. In this case, the code explicitly is avoiding a singleton pattern, so there isn't even a class being instantiated, so this is a true utility class.
However, the static methods are accessible from multiple objects, and as far as I can tell, the JVM is persisting the parameters in memory beyond the specific thread that called the static method to begin with.
The question I have is how the JVM handles this? Are these private parameters assigned memory and are indeed persisted independent of thread, since there is no class reference. I am working with byte code injection, and the assumption is that a direct reference to a static parameter is much faster to call than having to go through an object reference. Of course, from a programmer point of view, I much prefer the singleton pattern since I am so used to hang my hat on a class reference.
Thanks.

Are these private parameters assigned memory and are indeed persisted independent of thread, since there is no class reference. There is a class reference. It refers to the class, and is obtainable via the class literal; e.g., MyClass.class.

How does the jvm handle drawing images outside an applet window?

I have a question about an applet I want to optimize.
Essentially the applet allows the user to scroll through a large map while viewing only a small portion of the map through the applet window.
The map has a large array of circles with coordinates on the map that are drawn in their appropriate place in the applet window when the user scrolls the map.
As it stands, the paint method loops through every circle in the array to draw them, but most of them are not visible in the window and end up getting drawn in a negative coordinate or a very large coordinate.
My question is are these circles that are not seen in the applet window but are still calling drawCircle in the paint method putting a strain on the computer's graphics card?
Would it be better if I looped through all circles and only called the drawCircle method on circles whose coordinates would be visible? Or would the extra step of checking each circle's coordinates before drawing be not worth as efficient?
Any help would be appreciated.

If the amount of stuff being rendered outside of the clip rectangle is small then it's usually not worth it to attempt to figure out what's being clipped and not draw it. If the clip rectangle represents only a small portion of the entire canvas that can be drawn, however, it's usually worthwhile to put in some logic to only draw what is necessary.
Take JTextArea, for example. It could be displaying a text document thousands of lines long. Instead of rendering every line of text on every repaint operation, it contains the following logic:
1. Get the current clip bounds (i.e. what part of the text area is "dirty" and must be repainted).
2. Figure out what lines are displayed in the clip bounds. Some lines may be only partially visible (a line "halfway" scrolled down), but they need to be repainted too. If word wrap is disabled this is a very quick and cheap operation, but if word wrap is enabled, it's a little more complex.
3. Only repaint those lines.
This way, in the best-case scenario JTextArea only repaints a single line (the line the user is typing in). Worst case, it repaints the number of lines that can fit on the screen. But it never repaints too much.
Anyway, I guess my advice would be: If it's cheap and easy to determine if something is out of the clip bounds, do it. If it's difficult to determine, do it only if you have a noticeable performance issue in your rendering code.

How does the so-called duplicated data saved?

I am confused with this question now.
If a DB supports duplicate data. My question is: if I put 10 record, their data with same key, would BDB save key once and data 10 times, or 10 (same)key and 10 data?
I mean, the same key is "100001", different data are "a1", "a2", "a3", ..., "a10".
How they were kept in DB file?
like:
Type A:
"100001", "a1"
"a2"
"a3"
"a10"
or Type B:
"100001", "a1"
"100001", "a2"
"100001", "a3"
"100001", "a10"
If they are stored in "Type A" style, that must mean we can save a lot of disk space. And I would like to use a complex key rather than simple key.

Hi Lesslielee,
If your db is configured to allow duplicate data items, only one such equivalent key (the first) is stored in the database.
Best Regards,
Bogdan Coman

How does the interclass call the outerclass's method?

Compile the following code,
public class q extends JFrame
class c2 implements ActionListener{
public void actionPerformed(ActionEvent e7){
System.out.println(q.getTitle());
Get the errors:
non-static method getTitle() cannot be referenced from a static context
System.out.println(q.getTitle());
What can I do next step?
Thanks.

Accessing outer class
public class q extends JFrame
    class c2 implements ActionListener{
        Object outerClass;
        // constructor
        public c2(Object o) {
             outerClass = o;
        public void actionPerformed(ActionEvent e7){
            System.out.println(((q) outerClass).getTitle());
} example to create an instance of c2:
c2 c = new c2(this);

Isn't Outlook simply an email client or a software application on a computer? You can add an email account - whatever email provider that you use - right on the iPad. You can sync your Outlook contacts and calendar if that is what you are asking about, but Outlook itself has nothing to do with the iPad.

How does the "Windows 10 is free for its 1st year" offering affect licensing for enterprise customers paying Software Assurance?

At the keynote on 21 January 2015, there was an announcement that Windows 10 was going to be a free upgrade for the first year of its release.
As an enterprise customer, I'd like to know about the impact of this announcement on Software Assurance. How is the cost of Windows changing for the enterprise?

You are entitled to your opinion, that doesn't make it correct.
Personally, I'll go with Ed Bott since he has a much closer relationship
with Microsoft than you do:

"One thing's for certain: you won't have to pay Microsoft an additional

perpetual license that's good for the supported life of the PC, and there's
no plan at this time to offer Windows as a subscription."

How does the remote object connect to the correct host

i have had a small doubt on how the remote reference manages to find the correct host to call the subsequent methods after a sucessful lookup.
given a rebind or bind to the registry, the registry only stores the alias and the remote reference, now imagine a client calling a lookup on the registry would only get the remote reference, and not in which machine the remote object is found.
what i wanted to know is how does the client or atleast the remote reference returned by the registry correctly connects to the machine where the remote object is located. i dont think its stored in the stub bcos the stub is a complie time stuff.
i would be pleased to have a comprehensive answer for this.

The membership in the group communication framework is always accurate and upto date.Up to date to the moment when you check. Not up to date to the moment when you make the RMI call.
i could basically chk if this ip is available in the membership list.Complete waste of time. It doesn't matter what you check ahead of time, you are still trying to predict the future.
And you still have to deal with ConnectException etc from the actual remote method call. And the way you will deal with that in your situation is exactly the same as what you were going to do if your ahead-of-time check failed.
So just catch the exception(s) and deal with the problem there.

How does the iPod organize content?

When I manually add content to my video iPod, how does the iPod know where to put it? Does it go into Movies, Music, TV shows, podcasts, etc? Does it rely on the mp3 id tags??? If yes, can I force a movie to go into the music folder my simply changing mp3 id3 tags?
30G video ipod Windows XP Pro

1 I by its tag
2 depends on the files tag
3 No...mp4 and m4a files have diffrent tags then mp3s
In iTunes 6.0.5 if you change the "VIdeo Kind" it will sort correctly. Just right click file, and in the options tab change the setting under "VIdeo Kind".
Besides iTunes if you want to change a tag you have to use a mp4/m4a tag editor program like "YAMB ver 2 preview" it can change your tags and much more and its free http://yamb.unite-video.com/
you can try YAMB ver 1.6 but I don't think it works very well with tags.
