 Yeah, I think the policy should be consolidated, since java 1.1 is (for all I
 know) not packaged or availiable in Debian. Java-package supports nonfree
 runtimes starting from 1.3 and above. I assume that most of the software
 packaged in Debian these days will require a pretty modern runtime anyway.
 
 So, I'd suggest that the java(X)-runtime virtuals are removed in favour of a
 general "j-word-runtime" virtual to be provided by all runtimes capable of
 running programms written in the Java programming language.
 
 I propose using "j-word" instead of "java", because that is a time-honoured way
 of abbreviating four letter words that can not be said freely in English.[1]
 
 cheers,
 dalibor topic
 
 [1] As Sun Microsystems holds and and actively defends their Java(TM) trade
 mark, I would not recommend calling Kaffe a Java(TM) runtime, because, frankly,
 according to Sun Microsystem's rules for the usage of the trade mark, it is not
 a Java(TM) runtime.
 
 And that's fine by me, I don't feel that trying to rub off Sun's trade mark
 investment is a fair thing to do.[2] You can see on the kaffe.org web site how
 the Kaffe project tries to draw a clear line between Kaffe and Sun Microsystem's
 implementation. In order to avoid confusing people who dearly want the "Java(TM)
 Desktop System" GNU/Linux distribution, for example, rather than a free software
 runtime environment for programms written in the Java programming language (that
 is a safe use of the term "Java", btw. ;).
 
 [2] Just like I don't feel that Sun Microsystems attempts to market some of
 their clearly proprietary software as Open Source are a fine thing to do, like
 they tried to do with Java3D or JAI. See my comment at
 http://weblogs.java.net/blog/editors/archives/2005/02/working_with_th.html for a
 reference.

 - Why do JARs made with JBuilder 2006 Enterprise not work outside IDE???Hi all,
 
 I have written a program in JBuilder 2006 Enterprise (Win NT, JRE 1.5)
 which works perfectly within the IDE.
 
 However, when I use JBuilder to create a JAR of my project and then try
 to run in from the command line it throws the run-time exception
 below...
 
 Exception in thread "main" java.lang.SecurityException: class
 "Com.package.MyPackage.MyExcpetion"'s signer information does not match
 signer information of other classes in the same package
 
 I have used JARs before but never come across this sort of error, maybe
 worth adding that the program uses JavaMail to send emails.
 
 More confusing, why does it work in JBuilder, but not outside?!?
 
 Any help would be greatly appreciated, i am stumped!

 - hasNext?What is hasNext? I know you use it when you are reading from a file
 and it will stop when it has nothing more to read, but how would you
 use it? I have seen a couple of different examples of it, but all
 they do is make me more confused. I just can't seem to understand
 it...can anyone help?

 This is handled by the JSP container, i.e. on the server side.
 
 The path is hence relative to the JSP application.

 css is not JSP includes, but is part of the plain webbrowsing, i.e. handled
 from the *client* side.
 
 css is "requested for" by the the browser, i.e. the path is relative to the
 visible url.

 - Action selected state in JDK 1.5Hello all!
 
 Does anyone know of or have a solution of how to have automatic
 updates for buttons and menu items created from Action's FOR JDK 1.5?
 I know that automatic support for it was added in JDK (1.)6.0, however
 the requirements for the software I'm developing is Java 5...
 
 When calling new JMenuItem(Action) or JButton(Action), basically any
 radio button or checkbox AbstractButton component, calling setEnabled
 an the action turns the button AND menu items to gray. I would simply
 like to achieve that for the selected state as well: Whenever the user
 clicks on a toolbar button OR menu item, the selected state shall be
 reflected in the other GUI component, too. As stated above, a solution
 is inside the "too new" JDK6.
 
 So, has anybody implemented a solution for this? Maybe some
 AbstractAction subclass?
 
 Any help on this appreciated! (directions etc.)
 
 TIA

 - Database and java.sql.SQLException QuestionsHello everyone!! I am back for some more much need advice and assistance! I
 am creating a database for the first time. I am changing some programs I
 recently wrote to work with this database that have to do with Salesmen. I
 am getting the below error when I compile CreateDatabase.java. In that I am
 creating the database SalesDatabase and then creating 5 tables (Users, SType,
 Salesman, Sales, Product). The first thing I do is create those tables and
 then insert informtion into the SType table and Product table. SType is the
 SalesType of a salesman, meaning Entry, Junior or Senior that also has the
 bonus in there as another field (.05, .10, .15) and then product has product
 1, 2, 3, 4, and 5 with the corresponding price of each. After I do this I
 need to read in a text file (SalesInformation.txt) and calculate the sales
 based on the information in the database. So here are my questions:
 
 (1) What is the below error telling me, have I not set the database up
 correctly?
 (2) Am I on the right track with what I have below, should I be reading the
 text file as I am or should I change it to be its own method (anything you
 tell me would be apprecaited!!)?
 (3) Also, other than it not compiling...lol...I am unsure of the salestype
 part with element 6 on line 124. I read in ENTRY, JUNIOR or SENIOR from the
 salesinformation.txt file so how do I relate that with retrieving the bonus
 number from the database?
 
 Ok, I think that is enough questions for now. If anyone needs any additional
 information as to what I am trying to do, just let me know and I would be
 happy to fill you in!! I appreciate any hints or tips you may be able to
 give and I look forward to getting this thing working :)!! Thanks everyone!

 AGLOCO- this worries Google
 Bill Gates thinks Google should be worried!
 -------------------------------------------
 You must have heard by now about Agloco and how many people think it
 is going to be bigger than Google... Now Bill Gates is on record
 saying they have a great business model and that Google should be
 worried.
 
 Google search result produce - 1,400,000 web pages for Agloco.
 
 Google makes billions of $$$ and keeps it all for itself... Agloco
 one
 day is going to also make billions of $$$ except it will be completely
 shared out to its members!
 
 You make money with Agloco by using your computer as you would
 normally!
 
 Plus Agloco has a great referral pakage!
 So start building your network!

 It's all over the blogosphere and Bill Gates has been quoted as
 saying he believes it "will be the next big thing to hit the
 internet", so
 what is Agloco and will they really pay you for surfing the net?
 
 I too was sceptical when I heard about it but after spending a few
 hours googling and reading about it, I have not only come round to the
 idea but am now thinking it could really work and could really make
 us (that's me and all of you who are reading this) some money.

 - What is a "dirty read" ?Hi group,
 
 I am new to JDBC but have idea about Oracle transaction management. I
 am confused about JDBC documentation saying "dirty read"s allow
 changes made by a trasaction visible to another before it is
 committed. What does this mean ? Does it mean that the concurrent
 transaction can be from different connections ? If so how is it
 possible ? I believe read dirty reads are reads from dirty blocks
 which is accessible only by this session.
 
 TIA

 - j2ee request resource is not available hello1Hi all,
 I have found a solution to a problem that I would like to share.
 
 I am running WindowsXP and J2EE sdk 1.3.1.
 I was trying to run the Hello1 servlet example from the J2EE examples
 from sun. I found this error message: j2ee request resource is not
 available
 
 Then I solved this problem by opening the application in deploytool:
 Filling in the following fields:
 Hello1App: WebContext-> WAR File = Hello1WAR; ContextRoot = hello1
 GreetingServlet -> aliases = /greeting
 ResponseServlet -> aliases = /response
 
 This solved the problem and it was running fine.
 
 Hope it helps,

 - Can't avoid "References to generic type List<E> should be parameterized" warning here can I ?Hi,
 I'm writing some kind of gateway between 2 packages, whose a
 few classes have the same name (I need to bind these classes).
 
 So I'm retrieving the attributes of my source class1 and set my
 equivalent class2 in the other pkg with these attributes when
 methods names -and attributes- match.
 
 Excerpt from my method:
 1 public my.persistent.Pst mapFromProtocol(my.protocol.Pst src)
 2 {
 3 my.persistent.Pst target = new my.persistent.Pst();
 4 for (Iterator<my.protocol.Remark> it =
 src.getRemark().iterator(); it.hasNext(); )
 5 target.getRemark().add(it.next());
 6
 7 ... //many other attributes/objects to set too
 8
 9 return target;
 10 }
 
 In RAD the line 5 is underlined in yellow and it says "Type safety:
 The method add(Object) belongs to the raw type List. References
 to generic type List<E> should be parameterized".
 
 Is there a way to avoid this warning in my case, as I can't
 instantiate
 a List<Remark> lr = new ArrayList() of course... (because I have no
 method setRemark() in target)
 
 Thanks.
 Regards,
 Seb

 - Drawing on TabsHi all - I have an application where my main frame has a tabbed interface,
 and each tab has a JPanel.
 
 I would like to draw a line graph on the second tab (the first tab is where
 data is entered) and a bar graph on the second tab.
 
 The problem I have is how to draw on the second or 3rd tabs.
 
 I googled and one solution was to subclass the JPanel and then override the
 paintComponent() method. I tried but it doesn't seem to work. I am probably
 just doing it wrong.
 
 How would I go about defining/extending the JPanel class? or is there some
 other container that would serve this purpose better?
 
 Any help is appreciated.

 - Jedit: Error about MouseWheelListenerI installed the same Jedit archive on Windows and on HP-UX (with
 JavaVM-1.3). On
 Windows, it runs fine. On Unix, I get the following error message on
 startup:
 
 java.lang.NoClassDefFoundError: java/awt/event/MouseWheelListener
 
 Could it be that something is missing in my CLASSPATH? Where is the
 MouseWheelListener
 supposed to be? I thought this class was added in 1.4, but note that
 the
 installation notes for JEdit say that it can run under Unix with Java
 1.3.

 I think you're clutching at straws here, so what if people using dotnet were
 using VB6 or C++ in the past to do development?

 - "no cmp field defined in cmp ejb"I'm so boring I know... this is my problem...
 
 I wrote the following entity bean, it rappresents something like this:
 
 primary key id (managed by the container)
 foreign key formulation_product (cmp relationship field)
 foreign key ingredient (cmp relationship field)
 
 public abstract class FormulationComponentBean implements EntityBean {
 
 /* Relationship field getters */
 public abstract FormulationProduct getFormulationProduct();
 public abstract Ingredient getIngredient();
 /* Relationship field setters */
 public abstract void setFormulationProduct(FormulationProduct product);
 public abstract void setIngredient(Ingredient ingredient);
 
 [...create methods and others ejb* methods...]
 
 }
 
 When I try to autogenerate database table with Sun Deploytool I get this
 error message: "no cmp field defined in cmp ejb".
 
 I really do not need any persistent field, but only relationship field...
 should I insert a fake persisten field just to satisfy that silly utility?
 Or I am wrong on something?
 
 Thanks a lot for any help...

 - Reverse Engineer UML Diagrams From Source CodeI'm looking for a good tool that can automatically generatre UML
 diagrams from source code.
 
 I know Together can do this, but it's rather expensive....
 
 I was hoping for something open source. What are my options? What
 should I be considering? I plan to use it mainly for personal use for
 building medium sized applciations.
 
 I also found this one:
 
 http://jrefactory.sourceforge.net/
 
 Has anyone used it?
 
 TIA,

 - Preventing URLConnection from buffering entire output streamIn my client application, I upload huge files via HTTP.
 The URLConnection class seems to automatically buffer
 the entire contents, then when the OutputStream associated with
 the URLConnection is closed, it computes the length
 and prepends a Content-Length header before actually sending
 any bytes to the web server.
 
 This results in an OutOfMemoryException when the file is huge.
 
 My application uses Transfer-Encoding: chunked, but
 that doesn't help when the entire stream gets buffered anyway.
 
 Is there a way around this without writing my own URLConnection
 clone based on Sockets? Calling flush() on the OutputStream
 seems to have no effect.
 
 I understand that a workaround would be to use the new features
 of Java 1.5, but that's too new to expect end users to have.
 
 Any help would be appreciated.
 
 Thanks!

 - my JEditorPane.read() method is never referenced, why?[code]
 public class SimpleHTMLRenderableEditorPane extends JEditorPane {
 
 // borrowed from http://www.java2s.com/Code/Java/Swing-JFC/JEditorPaneandtheSwingHTMLPackage9.htm
 
 protected String getNewCharSet(ChangedCharSetException e) {
 String spec = e.getCharSetSpec();
 if (e.keyEqualsCharSet()) {
 // The event contains the new CharSet
 return spec;
 }
 
 // The event contains the content type
 // plus ";" plus qualifiers which may
 // contain a "charset" directive. First
 // remove the content type.
 int index = spec.indexOf(";");
 if (index != -1) {
 spec = spec.substring(index + 1);
 }
 
 // Force the string to lower case
 spec = spec.toLowerCase();
 
 StringTokenizer st = new StringTokenizer(spec, " \t=", true);
 boolean foundCharSet = false;
 boolean foundEquals = false;
 while (st.hasMoreTokens()) {
 String token = st.nextToken();
 if (token.equals(" ") || token.equals("\t")) {
 continue;
 }
 if (foundCharSet == false && foundEquals == false
 && token.equals("charset")) {
 foundCharSet = true;
 continue;
 } else if (foundEquals == false && token.equals("=")) {
 foundEquals = true;
 continue;
 } else if (foundEquals == true && foundCharSet == true) {
 return token;
 }
 
 // Not recognized
 foundCharSet = false;
 foundEquals = false;
 }
 
 // No charset found - return a guess
 return "8859_1";
 }
 
 public void read(InputStream in, Object desc) {
 System.out.println("do you see this?");
 try {
 super.read(in, desc);
 } catch (ChangedCharSetException e) {
 String charSet = getNewCharSet(e);
 System.out.println("charSet = " + charSet);
 try {
 in.reset();
 InputStreamReader reader = new InputStreamReader(in,
 charSet);
 super.read(reader, desc);
 } catch (ChangedCharSetException ee) {
 System.out.println("huh?");
 } catch (IOException ee) {}
 } catch (IOException e2) {}
 }
 
 }
 [/code]
 
 Per reference in http://kickjava.com/348.htm I am having to overwrite
 JEditorPane.read() with my own method, I still get
 ChangedCharSetException thrown when it should have been captured and
 you should have at least seen something in output, yet you see noting
 whatsoever except the ChangedCharSetException when you do this line:
 
 [code]
 // browser IS OF TYPE
 SimpleHTMLRenderableEditorPane
 
 browser.read(
 new BufferedReader(new
 StringReader(browser.cleanHTML(getURL()))),
 browser.getDocument()
 ); // SimpleHTMLRenderableEditorPane HAS
 METHOD cleanHTML(URL url) WHICH NEVER THROWS ChangedCharSetException
 [/code]
 
 Why is it that my method appears to never be referenced and the
 default read() method in JEditorPane is referenced instead? Ideas?
 
 Thanks

 - Write PNG from MemoryImageSourceI have an application which dynamically generates images using
 MemoryImageSource to produce a java.awt.Image object. I'd like to be
 able to write these images out as pngs.
 
 I've found the javax.imageio class which will write out pngs, but only
 from a BufferedImage and not from a basic Image. I've not been able to
 find a way to create a BufferedImage from an Image.
 
 Can anyone suggest how I can write out these images?
 
 Cheers
 
 Simon.
