- Graphics for ChessAppletHi Dears
I am developing chess game written as an JavaApplet.
Using Borland JBuilder 9 Personal Edition.
I use the following Code
void this_mouseDragged(MouseEvent e)
{
}
class Chess_this_mouseMotionAdapter extends
java.awt.event.MouseMotionAdapter
{
Chess adaptee ;
Chess_this_mouseMotionAdapter ( Chess adaptee )
{
this.adaptee = adaptee ;
}
public void mouseDragged ( MouseEvent e )
{
adaptee.this_mouseDragged ( e ) ;
}
}
But it seems that it still fire when the mouse button is released.
The Applet are on the following URL
http://w1.201.telia.com/~u20100003/Chess.html
Verry Thankfull for Tips or Advice.
Sincerely
Urban Avierfj?
Gotland, Sweden

- JNI: COM event sinks in a DLLhello,
I have created an Event-Sink class in C++ to handle COM-Events and it
works well in a MFC-application.
But if I create a DLL to use this Event-Sink-Class with the JNI then
the callback function of the event-sink is not called. The COM-Server
tells me that it is "overloaded" when it fires the event. It seems to
me that it "hangs" somehow in the JVM.
here some pseudo code:
in Java:
class Test {
public static native void nativeFunction();
public static void main(...) {
nativeFunction();
//during sleeping I fire the "event"
Thread.sleep(30000);
}
}
in the DLL:
class EventSink : public IDispatch
{
...
HRESULT __stdcall Invoke(...) {
//just exit application
exit(0);
return S_OK;
}
...
};
JNIEXPORT void JNICALL ...nativeFunction(...)
{
//initialize COM
CoInitializeEx(NULL, COINIT_MULTITHREADED);
//create COM object with CoCreateInstance(...)
//get IConnectionPointContainer of the object
//get IConnectionPoint* connectionPoint
//advise sink to connectionPoint
EventSink* sink = new EventSink();
connectionPoint->advise(sink, &cookie);
...
}
what is wrong in the code?
thanks in advance!

- OnLoad kicking off processGood Morning,
A friend of mine asked me a question the other day and I am fairly stumped.
Is there a way to use the onLoad function to kick off a process on the
server while the page is being painted? Want to send a message to a servlet
and then send the form to the servlet once the user has filled in the
values.
I did some webapp stuff a while back and we used the onload function to help
the page paint a little easier, I wondered if we could use it to send a
message, or if there was something in JSP or HTML that I overlooked.
Thanks,
M@

- Global Servlet FilterI'm writing a servlet filter that will keep track of the number of hits
for my site but the site is composed of several web applications. I'd
like to write it in such a way as to allow it to work with all of the
applications at one time, instead of tallying individual counts by hand.
Any pointers or suggestions are appreciated.
Thanks,

- looking for an open source java charting libraryHi All,
I am evaluating open source java charting libraries for use

JFreeCharts seems to fit the bill.

- in my applet I can't get the stop() and the start() to fireI cannot seem to see when the stop() and start() methnods fire when using
this applet. I thought when the focus moved away from IE6, the stop would
fire and then when it got the focus again the start() would fire. Is that
not the case?
Any ideas on what I could be doing wrong? Thank you.

- Eclipse - White space causing all text files to show up as having conflictsWhen we do a CVS synchornization in Eclipse, the Java files work well,
but ALL (dozens) of text
files show up as having conflicts, apparently because white space is
NOT being ignored. When
we ignore white space on a file by file basis, the conflicts disappear.
But we have not been
able to ignore white space globally, so we have to go through our
dozens of text files one by one, which
is very tedious and time consuming.
How do we GLOBALLY avoid white space characters causing text files
looking like they have
conflicts when doing an Eclipse CVS synchronize.

- Embedded underscoresI noticed Ruby has a convention I wish Java would implement. I think
it could be done without breaking existing code.
You simply permit the _ character to appear embedded in numeric
literals in Java source code. The lead _ would not be permitted, so
you still have no trouble telling a number apart from an identifier.
Then you might write a numeric literal like this:
2006_12_31
or
123_456_679
or
0x1234_5678
or
250_361_9093
or
1000_99
The _ is simply ignored. You use it to break the number up in
whatever way you choose to make it more readable.

- Earth to Sun: When will Java support closures now?Vitaly Lugovsky <email***@***.com> writes:
> No. It was added to make source files more readable.
How can something be more readable when anything in effect can be
replaced by a macro? You are perhaps focusing on #include and the
like; but the following is bad:
/* In some header file included somewhere while resolving
a source file */
#define foo fie
/* In the source file - will end up as fie()*/
int foo() {
}
To quote Wikipedia: "The use of preprocessors has been getting less
common as recent languages provide more abstract features rather than
lexical-oriented ones. Indeed, the overuse of the proprecessor might
yield quite chaotic code. In designing a new language based on C,
Stroustrup introduced features such as inline and templates into C++
in an attempt to make the C preprocessor less relevant."
> > Yes, again because they avoid strong typing.
>

Because the template has no idea whether the type parameter actually
supports the operations used inside it, e.g. a method call. In Java,
you cannot use an operation on a parametrized type unless you declare
that yes, this type shall conform to this interface/class.
> C and C++ are not strictly typed.
Not C, but every resource I've seen on C++ claims it is (by default),
though how strong anything is when it can be cast away as will is a
different question. Maybe you define "strong/strict typing"
differently from the makers of C++ and Java?

I am getting the impression "Lisp" is a mis-spelling for "Elitist".

You mean uninstall it again if you have
problems?
That would make sense, pity that is almost
impossible with Internet Explorer istelf,
or I suspect most people would remove it.
I do not think you will have any
problems with Mozilla, ..let us know.

Hi April,
Have you updated the PATH environment variable in XP? You should add the
path that points to the "bin" directory of your java installation. If
not, windows can't find the java.exe which is needed to execute any java
programs.
In addition (if your installer hasn't done it already) you should create
a new environment variable called JAVA_HOME (all uppercase), which
points directly to the directory of your java installation.
How to change/create environment variables in XP:

..yeah. That would probably be the relevant
question at this stage [ though I am glad to
hear you got the rest set up.. ]
NOTE: if you downloaded the 'no java'
version (hope you did not) you might
have to download it ..again.
Once you have, point it to the
quick-check link for applets..
<http://www.physci.org/pc/properties.jsp>
It should report java.vendor as
'Sun Microsystems Inc.'

...errrr. (whispers) I actually only use
Mozilla for testing my web-pages..
Unfortunately, since I do so much work at
trying to correct the way IE destroys
Java, I have to understand all its quirks,
and use it as my regular browser! :-(
Glad to hear I could point one more person
to a *good* browser though.. :-)

Make no apologies April, and thank you.
With the two donations I have received recently
(1 from a student in Ireland) I now have almost
half what the *huge* ads on my site have earned
over 4 months!
All the best with your new Java

Is the web service shown in bold in the solution explorer? Then it is set as
the startup project. Select the web project, right-click and choose "Set as
startup project" from the menu. You'll also need to select a page within
that project, right-click it and choose "Set as startup page".

- Compiling Java code using Ant within EclipseHi,
I am using Eclipse 3.0 to create a number of Java projects all located
within the same workspace. I had everything building ok but decided to
migrate to using Ant to try and manage things a bit better.
Now when I try and compile my app using Ant it does not find references
to external libraries. Now I suspect I need to specify the classpath in
the build.xml file, but is there a way of telling it to use the set of
libraries I have allready specified via Project->Properties->Java Build
Path->Libraries?
I currently have a build.xml file for each of the projects in my
workspace. Is there a way of creating a build.xml file which invokes
each of these in turn so that I can just do one big build?
Thanks for your help.

- String exceeding length - Getting absolute string lengthHello,
I am having a problem when inputting very long strings into a database.
The application I am writing can use different databases (thanks to
the wonders of JDBC) so this issue has been causing problems on both
Oracle and SQL Server.
Because one of the design objects was to support any JDBC compatible
database, a concern was raised about text widths. It was therefore
decided that the maximum column width for a VARCHAR would be a
configurable value. We theoretically knew that data could be more than
a single line so we introduced a sequence number to allow multiple
rows. (Don't ask me why we didn't use CLOBs instead, this is the
schema I'm stuck with.)
We now need to store base64 data in the same fields. The problem is
that in an example 4000 characters as defined by the Java string
object, its physical size is approximently 4430. This seems to be
because of the amount of mark-up involved, either in the base64 data or
possibly with the text between.
It occurs to me that while a non-ASCII value many be only a single
character in a unicode string, it is 6 characters in UTF-8. Therefore
I'm looking for a way of calculates the absolute length, rather than a
count of characters.
Is this possible or will I have to change the schema?

I looked for your concept of "Delegation" in the only book that I have
on UML. This is by Craig Larman. Its index does not evennnnn list it.
You should expand your query to other language groups. I can do it
for you. OOP implementation questions have been asked there before

- JSTL concatenateWell.. i wanna to concatenate a string... like:
String x;
while(true)
x += "x";
Then i get xxxxxxxxxxxxxxxxxxxx :)
How do i do that on JSTL?
Here is my code...
<c:set var="valorColuna" value="${rowValues.value}"/>
<c:forEach var="pk" items="${datagrid.primaryKeys}">
<c:set var="pkActual" value="${pk.columnName}"/>
<c:if test="${colunaActual == pkActual}">
<c:set var="pkValor" value="${valorColuna}{$valorColuna}"/>
I have tried without operators but it does not work. JSTL functions
also seem not to help (no concat function!)...
Any sugestions?
Thanks,

- Will MS be less evil now?I don't understand Gates. If he wants to do good deeds and be a
philanthropist, why limit such good deeds to healthcare and
education? Why not also do a good deed in the computer
industry? In this industry he is known less for his innovations
than for tactics such as sabotaging Java and cutting off
Netscape's air supply. He has done the industry and consumers
immeasurable harm, for example, by freezing the development
of web browsers. Here's an idea for Gates: Unfreeze the web
browser. Take web browsing to the next level. Start by
implementing SVG, the W3 standard for vector graphics, in IE.

- Junit: overriding original class private methodsI have a class that when run will call a private sendEfvent() method
that sends data to an external process. I would like to override that
behavior in testing and just report what is set to avoid the
complications, etc of having to use external processes during unit
testing.
I don't think I can just use an assertTrue() because I also want to
know how many times this private method is called (i.e. is it sending
the correct number of copies out)?
Is there a way I can cause Junit to stop the JRE from calling the true
sendEvent() method and instead call something in my test class??

- Preverifier error in Sun Java Wireless ToolkitHi ppl,
I'm using an SDK provided by my client and building a MIDlet
application which does ApiCalls on this SDK. I copied all the jar files
from the SDK and put it into my lib folder of my MIDlet project so that
it could add it to the classpath during build. But when I build it
shows the following error:
Error preverifying class com.myClient.sdk.attributes.AttributesMaster
VERIFIER ERROR
com/myClient/sdk/attributes/AttributesMaster.addErrorElements(Lorg/w3c/dom/Document;Lorg/w3c/dom/Node;[Lcom/myClient/sdk/attributes/model/ErrorSet;)Lorg/w3c/dom/Node;:
Cannot find class org/w3c/dom/Node
If I don't use that particular jar, and the rest of the jars, it
shows this error:
Error preverifying class com.myClient.sdk.call.AddDisputeCall
java/lang/NoClassDefFoundError: com/myClient/sdk/ApiCall
I read that this is because I might be using a class library created
for the J2SE platform and hence it doesn't work for the J2ME Wireless
toolkit which uses a limited JVM and APIs. Is there any way I can merge
it into my MIDlet so that it will use it?
P.S: I'm comparatively new to J2ME :( Also i'm using the Sun Java
Wireless Toolkit 2.3 Beta. Please help...
Thanks in advance,

- Help needed with Realm authorization and AuthenticationDear All
I'm somehow new to weblogic workshop, and i want to have a role based
security for a project.
I used XML based security in web.xml and in web-config.xml . Now i have
a problem, regarding to my project, i want for example, if role A was
logged in, to show him A in one pages of pageflow (for example
index.jsp) and if another role was logged in, not to show him the A.
I mean I want to have access to Roles in the pageFlow, and by knowing
which Role change the sequence of pageflow, do you ever reach this
problem ? any suggestions ?
I think there must be an API for accessing the realm security for
Weblogic.

- Apache Derby : create several instances.Hello.
I am using Apache derby database (Client network).
I see that when I create table it is created on an instance APP
(I don't know if instance is the correct word. sorry of my English).
I see that there are other instances (NULLID, SQLJ, SYS, etc).
Can I create an instance of my own in derby database, and how can I do that
?
(One instance may be used for repository, another for Datawarehouse, ...)
Another thing :
If I create several databases for te above reason (repository may be on
another db), how can I join them, when I am connected to database1, and want
to run a query that join both tables from database1 and database2 ?
Thanks :)

By "here", I assume you mean Germany, based on what you wrote below.
There are no such laws in the US with the exception of some states that
have "blue laws" that only apply on Sundays.
Your suggestion sounds like a nightmare where you never know what is

This is why any environment worth its salt has these routines available
in a standard library. Asking people to forgo a substantial reduction
in energy use for the (supposed) convenience of computer programmers is
ridiculous. Remember that computers are not an end unto themselves,
they are tools here to serve.

- how does picking and intersection works ?hi
I am interested i knowing how does the picking and intersection of shapes.
I am more concerned about picksegment and shape3d intersection. what's the
algorithm used and how effective it is. I am interested in the thoery of
all this than programming.
I am using pick segment to pind the intersection point, I have to find the
distance and than do some maths to find the intersection point, is there
an built-in function for this.
Thanks
