My JApplet contains a JPanel called jpanel1 size 210x210. I created a class myPanel which extends JPanel and I set its size to 210x210. myPanel contains a Canvas called canvas1 and its size is 210x210.But when I run the applet and draw an image to the canvas1, it isn't visible.

A scaled down version follows: public void write(String filename) throws IOException { int idx = filename.lastIndexOf('.'); if (idx >= 0) { File file = new File(filename); String format = filename.substring(idx + 1).toLowerCase(); ImageIO.write(image, format, file); } } The image has been instanciated using: image = new BufferedImage(w > 0 ? w : 1, h > 0 ? h : 1, BufferedImage.TYPE_INT_ARGB); ...where 'w' is the width and 'h' is the height. And given "img.png" I get a very nice PNG image. But "img.jpg" gives a weird result.

Message from Benny Dein Most recent post: 8/24/2007 3 authors and 5 replies. Hi I want to create a servlet or something similar by which im able to create virtual webservices. Lets say I would like to create a webservice with a method called 'getDate' which returnes the current date. This could be done by making a wsdl file (or whatever the name is) and via a wizard in some JAVA tool make a real webservice. This webservice'd be static since it creates a class in which I can make my code to return the date. The servlet should be published to a server and the behaviour cant be changed without compiling the class again and publish again. In that way it is static. I'd like to implement the same thing, but in af dynamic manner. By this I mean that I will create the wsdl file dynamically, when a client requests for that and I would dynamically construct the soap response, when the client makes a request on my method. So to the client it should seem exact as a static normal webservice but the implementation on the server is totally dynamic, and any xml returned from calls to my 'webservice' should be created dynamically. Can anyone guide me in how to implement this? Which .jar files do I need, where do I get them from, which classes can help create wsdl files and soap webservice responses? Can it be implementet in a normal servlet or do I have to code my own http server? Links to guides'd be appreciatet. Thanks in advance, Benny read more about How to create virtual webservices?
Message from Mothra Most recent post: 8/16/2007 2 authors and 2 replies. ... is that it doesn't return the length of the bit set. For example, if I create a new 8-bit set: BitSet eightBits = new BitSet(8);Running eightBits.length() returns zero, rather than eight. The problem is that I want to be able to convert the bit set back to an integer at some point. I thought the easiest way'd be to iterate backwards over the bit set thus: private static int bitsToInt(BitSet bits) { int myInt = 0; int binColumn = 1; // loop over the bitset backwards, adding up the true values for (int i=(bits.length()-1); i>=0; i--) { myInt += (booleanToInt(bits.get(i)) * binColumn); binColumn = (binColumn * 2); } return myInt; } But because BitSet.length only returns the length from the highest bit that's set to "true", this does not work for any binary numbers that start with zeros in the full bit set (e.g. an 8-bit set of '00111000'). I suppose my method could take in a 'length' parameter that I coul define, but is not there a neater way of getting the true length of a BitSet? read more about Problem with BitSet.length()...

Message from jupiter Most recent post: 7/1/2007 3 authors and 4 replies. The Collections class is supposed to, among other things, return type safe collections from existing collections with static methods such as .checkedList(). My question is: What is so special about these static methods since we can do the same thing by declaring the original list generically with a type like <String>? I mean, once you create the list with <String> the compiler will no longer allow you to add, say, Integer to the list. So what purpose does .checkedList() provide in that context? Maybe it's all about backward compatibility? read more about Collections.class methods anachronisms?

Message from mlw Most recent post: 6/29/2007 4 authors and 15 replies. Don't take anything about this, it isn't a flame or troll, while I'm not new to JAVA I favor C++. However, I may need to use it in a contract position, and am concerned that the restrictions it places on application code. Take, for instance, this C++ construct: class foo { char *m_name; .... void * operator new(size_t size, char *string); }void *foo::new(size_t size, char *string) { size_t cbstr = strlen(string)+1; size_t cb = cbstr + size; foo * t = (foo *) malloc(cb); char * name = (char *) &t[1]; strcpy(name, string); t->m_name = name; } The above example is a methodology that can be used to reduce the CPU and memory overhead of malloc. You my argue that this isn't a valid concern, but if you've 10 or 100 million objects, the malloc block overhead, alone, make this worth while. Hint: This is actually a simplification, some times malloc isn't used at all, and a big array is pre-alocated and work through it with each new.Is there a way to create 10 to 100 million objects in JAVA with a reasonable system configuration? read more about C++ vs JAVA "new" (no flame war please!)

When I run a game applet and then reload the page, two instances of the game are running in the same VM. I have verified this with JMP (http://www.khelekore.org/jmp/), and as the more recent games use lots of memory (up to 42 megs), they run out of memory and throws a: Exception in thread "Image Fetcher 0" JAVA.lang.OutOfMemoryError: JAVA heap space JAVA.lang.OutOfMemoryError: JAVA heap space If not on the first reload then on the second or third.

I have the following in the applets destroy() method: public void destroy() { System.out.println("Applet destroyed"); applet = null; appletAdapter = null; if (engine != null) { engine.destroy(); engine = null; } System.gc(); } 'applet' is a reference to the applet itself. 'appletAdapter' is a proxy for calling methods on the applet (games can also run as an application so this object implements methods for getting "host", "applet parameters" and calling JAVAScript without the need for an actual applet).
