- JDBC QuestioComing from the world of VisualBasic, I'm not find Java too hard to catch on
to. After just a couple of weeks of real coding, I'm even cranking out some
code to access a MySQL database. I've got something of a conceptual hill to
jump over, and that's about the Statement class. In VB, I'm used to using
ADO, and just opening a connection and then running queries against it
(either record sets or update-style queries). Is it just the case that any
code I'm translating I just need to insert the lines dealing with the
Statement class, and that's it? What is the purpose of Statement?

I'd like to change the L&F of the JTable Header but I'm not sure how to do

- retrieving CPU Usage and Memory Usage information in JAVAHi All,
I 've been searching through this group for information on CPU and
Memory usage retrieval on Windows machine using JAVA. After following
so many previous threads on the same subject, the possible solution I
've observed was using JNI calls to native libraries for these OS
specific information retrieval.
Later I found that java management libraries already has it, native
libraries and some jmx classes.
Sharing the code, hope this may help group members in their
requirements.
Code:
com.sun.management.OperatingSystemMXBean mxbean =
(com.sun.management.OperatingSystemMXBean)
ManagementFactory.getOperatingSystemMXBean();
System.out.println("********* CPU & MEMORY USAGE OF \\harsh
*********");
System.out.println("OS : "+mxbean.getName());
System.out.println("Available Processors :
"+mxbean.getAvailableProcessors());
System.out.println("Commited Virtual Memory :
"+mxbean.getCommittedVirtualMemorySize());
System.out.println("Free Physical Memory :
"+mxbean.getFreePhysicalMemorySize());
System.out.println("Free Swap Space Size :
"+mxbean.getFreeSwapSpaceSize());
System.out.println("Process CPU Time : "+mxbean.getProcessCpuTime());
System.out.println("Total Physical Memory Size :
"+mxbean.getTotalPhysicalMemorySize());
System.out.println("Total Swap Space Size :
"+mxbean.getTotalSwapSpaceSize());
Problem:
getProcessCpuTime() method returns the CPU time used by the process on
which the Java virtual machine is running NOT the '%CPU Usage' time
which i was hoping to get.
If anyone is having idea about how to obtain '%CPU Usage' of windows
machine using java program, kindly post the message.
Regards,

- Need help creating a grid.Hello I am new to Java AWT/Swing and have a question.
I would like to create a 10x10 grid, where each "cell" can handle mouse
events. So if I click on cell with a coord A4 then it would change color.
I was thinking of using JButtons but I want the "cells" to look more like
Excel-like in appearance. I also found a component called JTable but I do
not think that it can handle mouse events. Any suggestions??

Thanks in advance

- How to get mozilla to download a jar file?
I can download jar files without difficulty using Internet Explorer,
but Mozilla instead "displays" them (i.e. fills the screen up with
gibberish).
Does anyone know how to configure Mozilla to download jar files
and save them to disk?
Or is this a server-side problem? (FWIW, I noticed that the server
serving the jar files in question put "text/plain" in the Content-Type
field.)
TIA,

- Offset not calculated properlyI'm trying to move a second window so that it is directly above another,
hugging it closely. I'm using the below code, but for some reason, its not
always consistent.. sometimes my second window falls just below the title
bar, sometimes its pretty far below the title bar.
void resetPositionComboTD()
{
Point loc = this.getLocationOnScreen();
int newY = loc.y - sw.getHeight();
int newX = loc.x;
sw.setLocation(newX, newY);
}
I tried playing with insets, but no matter what I did, it didn't seem to
help much (or at all)
Any help is appreciated, I'm driving my self nuts with this

java-programmer, Servlet-to-JSP using Tomcat 4.1
Im running Tomcat 4.1 with JDK 1.4.2 on Win XP SP1
I have made a simple database search page (using MSAccess) that fetches
records using jdbc odbc drivers.
A servlet does the database processing, puts the finished search results
into a vector (each result is represented by a javabean) and i use the
following code in doPost():
session.setAttribute("results",l_vecTmp); // l_vecTmp is the vector
ServletConfig sc=getServletConfig();
ServletContext sx=sc.getServletContext();
RequestDispatcher rd=sx.getRequestDispatcher("/results.jsp");
rd.forward(req, res); //the 2 params are the standard httpservlet request
and response objects that were passed to the servlet
In the JSP, I use the following code:
<%! int i;
Vector l_vecTmp;%>
<%! SearchResultBean l_srb;
int l_iSize=l_vecTmp.size(); %>
<% try
{
l_vecTmp=(Vector)request.getAttribute("results");
}
catch(Exception e)
{
e.printStackTrace();
}
%>
The directory structure is as follows-
Location of results.jsp:
<tomcat-root>\webapps\studentsearch
Location of servlet:
<tomcat-root>\webapps\studentsearch\WEB-INF\classes
When I run the application, I get a JasperException in the servlet, at the
requestdispatcher line.
Does it mean the servlet cant find the JSP?
Do i have to add the JSP to the web.xml deployment descriptor?
ANy help appreciated

java-programmer >> Servlet-to-JSP using Tomcat 4.1
I have packaged my classes, and put them where you mentioned. The bean and
servlet belong to the same package.(com.rex.studentsearch)
The JasperException is thrown when I forward the request from the servlet to
a JSP page. The servlet executes the database query (on Access, using the
odbc bridge), puts the results into a vector, adds it to the HttpSession,
and then calls getRequestDispatcher().forward() with the jsp as the target.
I separated the code into separate method invocations-
ServletConfig sc=getServletConfig();
ServletContext sx=sc.getServletContext();
RequestDispatcher rd=sx.getRequestDispatcher("/results.jsp");
rd.forward(req, res); --->This is where the exception is thrown.
The JSP compiled without problems the first time round.
Perhaps the path to the JSP is wrong? It is placed in the application
folder, in this case webapps/studentsearch.
So i suppose the correct invocation would be ./results.jsp, relative to
studentsearch

- How to create an object of a given class NAME?I got the following piece of code:
static private Idiom determineIdiom(Locale region) {
if (region==null) region=DEFAULT_REGION;
String language=region.getLanguage();
if (language==null) language=DEFAULT_LENGUAJE;
Idiom myIdiom=null;
if (language.equals("es")) { myIdiom=(Idiom)new
Idiom_es();
} else if (language.equals("en")) { myIdiom=(Idiom)new
Idiom_en();
} else if (language.equals("ca")) { myIdiom=(Idiom)new
Idiom_ca();
} else if (language.equals("fr")) { myIdiom=(Idiom)new
Idiom_fr();
} else {
myIdiom=(Idiom)new Idiom_es(); //default
}
return myIdiom;
}
All the Idiom_* classes extend Idiom, which in turn implements an
interface. If I want to add support for a new language (say, finnish),
I
have to write a Idiom_fi class AND I have to put a new if sentence in
this method:
} else if (language.equals("fi")) { myIdiom=(Idiom)new
Idiom_fi();
I'd like to get rid of the second requirement, and for that I'd need to
be able to
compose the name of the class I want to instance, sorta like this:
myIdiom=(Idiom)new {{"Idiom_"+language}}();
I'm not sure if this can be done in Java. Can it?
Thanks in advance.

- How to let a user put objects in a scene?x-no-archive: yes
Hello, all.
I'm about to write a 3D-editor for neuronal morphologies.
Picking in existing morphologies works, now I'm trying to get it
to enable an user to interactively create and place new objects
in the scene, thus building new models from scratch.
When clicking at the Canvas3D, I receive 2D-coordinates, as expected.
But for placing a new object, I'd obviously need 3D-coordinates.
Is there any way for me to have the objects appear at a "somehow
reasonable" depth regarding any existing morphology? It does not
necessarily have to be the exactly correct placement, since the user
will be able to adjust it after it has been created.
But in most cases one will of course want to add a new object close
to an other.
I could imagine to create any new object in a given distance to
the near clipping plane (or just half the distance 'tween the near
clipping plane and the model itself) as a quick hack.
Is there any better way to solve this?
Can one somehow determine the SGO that is closest to where the
MouseEvent occurs /without/ picking? Picking (of course) only works
when clicking on SGOs that are already present.
In my case, I'd have to calculate some position in 3-space without
the picking engine, since I've got nothing to click on, but the raw
Canvas3D.
Thanks in advance for any answers.
Regards,
Andr?

- Fixing and Continuing feature for Java IDE?I read that NetBean have it, I try simple main code:
public static void main(String[] args) {
// TODO code application logic here
int a=3;
a=9; <<<<<<<
}
I try to change the Value assignment to "a" at last line. and I realize
that no way to execute this line again. in short no way to step
reverse. so for this cases we need to change current value in watches
window and change the source code for next run. it's true?
but what we can do if have a complicate algorithm and have fix with
some parameters, how we suppost to use with this featurse?
I read about stack call, but I try this code:
static int aa(){
return 6;
}
public static void main(String[] args) {
// TODO code application logic here
int a=3;
a=9;
a=aa();
a=5;
}
but the call stack on run menu stil grayed and not available. and bad
from this, the debugger point to wrong line when i step into aa()
function?
Have some one to help? or have another group for NeBean
Maybe have some another IDE with this feature?
thanks

After days of researching, reconfiguring, reinstalling etc and it not

- static hashtable with conent?Did not find out the answer after some google:
how can we create a static hashtable with some initial values there?
static Hashtable ht = new Hasthable();
will only create a empty one. Suppose I want to put some Integer
values as keys and values of this hashtable, how can I do that?
The reason for it is that I am writing a "utility" class, with all the
functions as static. These functions will need to check a fixed
hashtable for some operations.
Thanks a lot. :-)

- Accessing cvs from a java applicationHi all,
I am writing a small image processing application using java. All of
my image data is currently stored in a cvs repository so the java
application needs to be able to checkout files from the repository and
then check them back in when done with the processing.
Any suggestions on the easiest way to do this? (Hopefully with an
example somewhere ;-) I spent a little while searching the newsgroups
but there is a lot of conflicting info out there.
Thanks,
Stu

- Quick question on polymorphism and instanceofPlease consider:
===================
public class ClassA {
public void someMethod(ClassB objB) {
//...
}
}
===================
public class ClassB {
}
===================
public class SubClassB extends ClassB {
}
===================
public class Main {
private static class SubClassA extends ClassA {
public void someMethod(ClassB objB) {
if (objB instanceof SubClassB) { //<------ see question
below
//...
} else {
super.someMethod(objB);
}
}
}
private ClassA objA = new SubClassA();
public ClassA getClassA() {
return objA;
}
}
====================
Question: Can I avoid the use of the "instanceof" operator, if yes how?
With thanks,

- tomcat 5 and apacheHi all;
Can anyone point me to the documentation for getting Tomcat 5 to work with
Apache? I have just gotten Tomact running on my test server (RH Linux 7.3),
Apache's there also. I Can't find the Docs on the jakarta site. The links
that come with tomcat point to the download page. All the documentation I
can find is about Tomcat 4. Is Tomcat 5 too new to use? Am I losing my
mind? Perhaps.

- HttpUnit throws java.lang.NoSuchMethodError as soon as I attempt to create a WebConversation.On 14 Aug 2003 02:14:33 -0700, email***@***.com (thomas) two-finger

Normally, you would need the source code of NekoDOMParser to be able to see
what is going on exactly.
But I think that the version of nekohtml.jar you are using requires a
specific minimum version of either the servlet engine, the JDK, or perhaps
another library it needs and is available in an older version only.
What is happening here, is that NekoDOMParser is using a method in a class
that does not exist in the actual class you have on your system.
Example:
JDK 1.02 would throw the same error on Button.addActionListener(), because
it did not have the listener system implemented yet.
JDK 1.1 would run it fine, however.
So: check your requirements for that library.

- Hotkeys questionAll,
I am currently looking at doing the following. Using a JtextArea/field
create a box that will allow the users to enter hotkeys/shortcut keys.
When you click the box it will only take in the key pressed and display
that (e.g. if you press "a" A will appear, if you press crtl, alt,
shift and b "Crtl + ALT + SHIFT +B" would be displayed.
Does this class exist already (GPL pref).

- Embedded DB or XML storage optionsHi,
We are trying to determine what is the best storage method for our
application. We are partial to XML and would prefer a solution based on
this format.
Or maybe going from an RDBMS, like this one:
http://hsqldb.sourceforge.net/ to XML (through a Save operation or
Export) is a better choice for speed? (storing XML data on the fly is
probably slower then RDBMS?).
Any suggestions would be appreciated.
Thanks,
