Desperately need some help with client-server java programming

Hi all,
I'm new to client server java programming. I would like to work on servlets and apache tomcat. I installed the apache tomcat v 5.5 into my machine and i have sun java 6 also. I created a java applet class to be as a client and embed it into an html index file, like this:
<applet code="EchoApplet.class" width="300" height="300"></applet>However, when I try to run the html file on the localhost, it print this error: classNotFoundException, couldn't load "EchoApplet.class" class. On the other hand, when I open the index file on applet viewer or by right clicking, open with firefox version 3, it works.
I thought that the problem is with firefox, but after running the applet through the directory not the server, i found that the problem is not any more with firefox.
Can anyone help me to solve this problem. I'm working on it for 5 days now and nothing on the net helped me. I tried a lot of solutions.
Any help?

arun,
If the browser is going to execute $myApplet, first it must get the $myApplet.class from the server, right?
So it follows that:
1. $myApplet.class must be acessible to server, and
2. the server must know exactly where to find $myApplet.class
So, the simplest solution is to is put the $myApplet.class in the same directory as the HTML file which uses it... then your applet tag is simple:
<applet height="200" width="400" code="$myApplet.class" ></applet>* The height & width attributes are required
* Note the +.class+ is required in the code attribute (a common mistake).
* This works uniformly (AFAIK) accross all java-enabled browsers.
* There are incompatibilities with the codebase attribute. Poo!
Cheers. Keith.

I need some help with my server's permissions asap!

Well, I am here for a reason as you can tell from my subject. Before I ask my question, I will explain my setup so you have a better understanding of what I am trying to do.
I have an intel iMac running Mac OS X Server 10.5. It is setup at home with about 4-5 services running for personal use. It is an Open Directory Master machine. I have clients setup to connect to the server and everything is running well, except for USER permissions. I have TWO partitions on the machine. One is smaller than the other. The first one has my system files along with applications/local users. The second one is used for network home directories and backup storage. So there is only a bootable system on the first partition. Now for my questions:
I know as time goes on, user permissions or even system permissions modify and need to be "repaired" using Disk Utility. I am able to successfully repair the system permissions, but I CANNOT repair network user home folders on the second partition because there is no OS installed on it. If you see what I am trying to do here, please advise the best possible solution. No, I cannot start over. I just want to repair permissions for the users located on another partition other than the one where the OS system files are located.
Thank you.

I didn't say it didn't check user permissions... (if by user permissions you are talking about who owns a file.) I'm saying it won't check user home directories or backup directories.
From Apple's knowledge base article: http://support.apple.com/kb/HT1452
{quote}Files that aren't installed as part of an Apple-originated installer package are not listed in a receipt and therefore are not checked.{quote}
Also in that KB article it explains what Disk Utility does, which is to verify the ownerships and permissions of every file and directory installed from an Apple-originated installer package. Things like iTunes library files aren't installed from a package, they're created by iTunes.
To see all the files and directories that might be checked by Disk Utility run:
find /Library/Receipts -name '*.bom' -exec lsbom {} ;
The command above doesn't distinguish between Apple originated or third party packages, so it actually shows more than what Disk Utility checks. If you limit the output to what gets checked under /Users there is only this:
./Users/.localized 100644 0/0 0 4294967295
./Users/Shared 41777 0/0
./Users/Shared/.localized 100644 0/0 0 4294967295
Now, regarding the "iTunes Library file is locked..." problem, I'll assume that you've already verified the user owns 'iTunes Library' and 'iTunes Music Library.xml' in their ~/Music/iTunes folder and that they have read/write access to these files. If there is a chance that iTunes crashed before this problem occurred, it's possible there is still a lock on one or both of the files. The simplest fix is just to reboot the client machine. If you want to fix it the hard way, you can copy the two files to another directory, delete the originals (which have the locks), then copy the backup files to the ~/Music/iTunes folder.

I need some help with sound in Java

hi, i`m new to java. i`m having a through problems with a program i`m writing. i`ve added a song to an applet but it does not play. The code for this is:
private AudioClip music;
music = getAudioClip(
getDocumentBase(), "titantic.wav" );
Can some 1 tell me is that the write code. please help.

2 things.
1. You must also send a command to play the music file.
2. I'm not certain, but I think that you can only load .au files this way.

Need some help with tools for java projects

Hi Friends,
I just want to know what software release management tool do you use.Is there any free tool available on net??
I do not need a subversion tool( cvs,svn etc) or a automation build tool ( luntbuild, cruisecontrol, anthill) , I am looking for some tool,that helps you manage the release after its made.For example,i would like to track down which release was made to which customer on which date,how many releases were made to any particular customer,what source code was shipped to the customer..and so on....
Is there any such tool that can accomplish this???
Thanks

Please I need some help with a table

Hi All
I need some help with a table.
My table needs to hold prices that the user can update.
Also has a total of the column.
my question is if the user adds in a new price how can i pick up the value they have just entered and then add it to the total which will be the last row in the table?
I have a loop that gets all the values of the column, so I can get the total but it is when the user adds in a new value that I need some help with.
I have tried using but as I need to set the toal with something like total
    totalTable.setValueAt(total, totalTable.getRowCount()-1,1); I end up with an infinite loop.
Can any one please advise on some way I can get this to work ?
Thanks for reading

Need some help with threads...

Hello all,
I am working on a project at work, and I am not the best programmer in the world. I have been trying to get my head around this for a couple of days and just cannot get it to work.
I am writing an instrumentation control program that will have three threads. One is the GUI, one will receive control information and set up the hardware, and one will check the hardware status and report it to the GUI periodically. I plan on using the invokeLater() method to communicate the status to the GUI and change the status display in the GUI. Communication from the GUI to the controller thread and from the status thread to the controller thread I had planned on being piped input/output stream as appropriate. I have a control class and a status class that need to be communicated over these piped streams. In some trial code I have been unable to wrap the piped input/output streams with object input/output streams. I really need some help with this. Here is the main thread code:
package playingwiththreads1;
import java.io.*;*
*public class PlayingWithThreads1 {*
public static void main(String[] args) {*
* PipedOutputStream outputPipe = new PipedOutputStream();*
* ObjectOutputStream oos = null;*
* ReceiverThread rt = new ReceiverThread(outputPipe);*
// Start the thread -- First try*
* Thread t = new Thread(rt);*
t.start();*
// Wrap the output pipe with an ObjectOutputStream*
try*
oos = new ObjectOutputStream(outputPipe);*
catch (IOException e)*
System.out.println(e);*
// Start the thread -- Second try*
//Thread t = new Thread(rt);*
//t.start();*
/** Send an object over the pipe. In reality this object will be a
class that contains control or status information */
try
if (!oos.equals(null))
oos.writeObject(new String ("Test"));
catch (IOException e)
try
Thread.sleep(5000);
catch (InterruptedException e)
I read somewhere that it matters where you start the thread relative to where you wrap piped streams with the object streams. So, I tried the two places I felt were obvious to start the thread. These are noted in the comments. Here is the code for the thread.
package playingwiththreads1;
import java.io.*;
public class ReceiverThread implements Runnable {
private PipedInputStream inputPipe = new PipedInputStream();
private ObjectInputStream inputObject;
ReceiverThread (PipedOutputStream outputPipe)
System.out.println("Thread initialization - start");
try
inputPipe.connect(outputPipe);
inputObject = new ObjectInputStream(inputPipe);
catch (IOException e)
System.out.println(e);
System.out.println("Thread initialization - complete");
public void run()
System.out.println("Thread started");
try
if (inputObject.available() > 0)
System.out.println(inputObject.read());
catch (IOException e)
System.out.println(e);
Through testing I have determined that no matter where I start the thread, the thread never gets past the "inputObject = new ObjectInputStream(inputPipe);" assignment.
Could someone please help me with this? There are other ways for me to write this program, but this is the one that I would like to make work.
Many thanks in advance,
Rob Hix

Thanks for the help, but that did not work. I tried flushing the ObjectOutputStream and it is still hanging when initializing the thread.
Here is a better look at the code since I was helped to figure out how to insert it:
The main method:
package playingwiththreads1;
import java.io.*;
public class PlayingWithThreads1 {
    public static void main(String[] args) {
        PipedOutputStream outputPipe = new PipedOutputStream();
        ObjectOutputStream oos = null;
        ReceiverThread rt = new ReceiverThread(outputPipe);
        // Start the thread -- First try
        //Thread t = new Thread(rt);
        //t.start();
        // Wrap the output pipe with an ObjectOutputStream
        try
            oos = new ObjectOutputStream(outputPipe);
            oos.flush();
        catch (IOException e)
            System.out.println(e);
        // Start the thread -- Second try
        Thread t = new Thread(rt);
        t.start();
        /* Send an object over the pipe. In reality this object will be a
         * class that contains control or status information */
        try
            if (!oos.equals(null))
                oos.writeObject(new String ("Test"));
                oos.flush();
        catch (IOException e)
            System.out.pringln(e);
        try
            Thread.sleep(5000);
        catch (InterruptedException e)
}The thread code:
package playingwiththreads1;
import java.io.*;
public class ReceiverThread implements Runnable {
    private PipedInputStream inputPipe = new PipedInputStream();
    private ObjectInputStream inputObject;
    ReceiverThread (PipedOutputStream outputPipe)
        System.out.println("Thread initialization - start");
        try
            inputPipe.connect(outputPipe);
            inputObject = new ObjectInputStream(inputPipe);
        catch (IOException e)
            System.out.println(e);
        System.out.println("Thread initialization - complete");
    public void run()
        System.out.println("Thread started");
        try
            if (inputObject.available() > 0)
                System.out.println(inputObject.read());
        catch (IOException e)
            System.out.println(e);
}Does anyone else have and ideas?

Need some help with MDX formula

Hello, I am not finding any good documentation on MDX formulas, there is a specific one that I need some help with....could someone please elaborate what exactly does this formula mean? thanks.
(MEASURES.[SIGNEDDATA],
CLOSINGPERIOD([%TIMEDIM%].
[%TIMEBASELEVEL%]))

If new MEASURE gets added to Measure's table , in BPC Client , etools->client Options-> Refresh Dimensions should get the new measure into the CurrentView .IF not try etools->client Options-> Clear Local application information .
Formula 2 :
(MEASURES.SIGNEDDATA,
CLOSINGPERIOD(%TIMEDIM%.
%TIMEBASELEVEL%))
This formula is used to retrieve AST & LEQ account values.
If current time member is at monthlevel ,ie ClosingPeriod of 2011.FEB is the current member it self ,and would retrieve 2011.FEB value.
If Current time member is at quarter level then ClosingPeriod of 2011.Q1 is 2011.Mar ,and would retrieve 2011.MAR value.
If Current time member is at year level then ClosingPeriod of 2011.TOTAL is 2011.DEC ,and would retrieve 2011.DEC value.
Formula 1 :
MEASURES.SIGNEDDATA
Irrespective of the level of the Time , MEASURES.SIGNEDDATA would retrieve current Time member value.This formula is used to retrieve INC & EXP account values
if current time member is at month level,2011.FEB , 2011.FEB value is retrieved.
if current time member is at quarter level,2011.Q1 , 2011.Q1(JANFEBMAR) value is retrieved.
if current time member is at year level,2011.TOTAL , 2011.TOTAL(JAN,FEB,....,DEC) value is retrieved.
Hope this helps.

Error 1603: Need some help with this one

When installing iTunes I first get an error box saying
"Error 1406: Could not write value to key \Software\classes\.cdda\OpenWithList\iTunes.exe. Verify that you have sufficient access to that key, or contact your support personnel."
The second one (after I click on Ignore on the last box) I get it this one:
"Error: -1603 Fatal error during installation.
Consult Windows Installer Help (Msi.chm) or MSDN for more information"
Strange thing is that I do have full access to my computer (or atleast in all other cases I have had since I am the only one with an account on it).
I have done my best in trying to solve it myself but I'm running out of ideas. I have downloaded latest versions from the website and tried installing Quicktime separately. I have also tried removing Quicktime using add/or remove programs though I just I didn't dare to take full removal because it said something about system files.
Anyway I really need some help with this, anyone got any ideas?

Do you know how to count backwards? Do you know how to construct a loop? Do you know what an autodecrementor is? Do you know how to use String length? Do you know Java arrays start with index 0 and run to length-1? Do you know you use length on arrays too? Do you know what System.out.println does?
Show us what you have, there isn't anything here that isn't easily done the same as it would be on paper.

Need some help with a Macally enclosure and a spare internal drive

Need some help with a Macally enclousure

Aloha:
I have a Macally PHR-S100SUA enclousure that does not recognise,my WD 1001fals hard drive. It has worked just fine with other internal drives, but not this one?
This is a spare internal drive that I am trying to make an external drive to store back ups for a lot of data. But so far I can not get it recognized by the computer. Maybe I need different drivers?
Any suggestions?
Dan Page

Hi-
Drivers aren't typically needed for external enclosures.
Macally has none listed for that enclosure.
The same is true for the WD drive, internal or external; no drivers.
With the exception of high end PM multi drive enclosures, I can't think of any that use drivers.
How is the external connected?
Have you tried different cables, different ports?
Bad/damaged cables are fairly common.
Have you verified connections inside of the enclosure?

Need some help with putting a folder in users directoryI recomend using System.getProperty( "user.home" ) not a hard-coded value.
This will use the users home folder ( C:\My Documents ) on Win9X (I guess), C:\Documents and Settings\<current user> on Win2K +, and ~ on Unix-a-likes.

Need some help with downloading PDF's from the net.

need some help with downloading PDF's from the net. Each time I try to click on a link from a website, if it takes me to a new screen to view a pdf, it just comes up as a blank black screen? any suggestions?

Back up all data.
Triple-click the line of text below to select it, the copy the selected text to the Clipboard (command-C):
/Library/Internet Plug-ins
In the Finder, select
Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
From the folder that opens, remove any items that have the letters “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari, and test.
The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present.
If you still have the issue, repeat with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again.

Need some help with the Select query.

Need some help with the Select query.
I had created a Z table with the following fields :
ZADS :
MANDT
VKORG
ABGRU.
I had written a select query as below :
select single vkorg abgru from ZADS into it_rej.
IT_REJ is a Work area:
DATA : BEGIN OF IT_REJ,
        VKORG TYPE VBAK-VKORG,
        ABGRU TYPE VBAP-ABGRU,
       END OF IT_REJ.
This is causing performance issue. They are asking me to include the where condition for this select query.
What should be my select query here?
Please suggest....
Any suggestion will be apprecaiated!

I guess this will fix the issue correct?

Need some help with ".png" image.

Good day everyone. Here's the run down. I need to add an
image (image "A") ontop of another image (image"B"). Image "B" is a
paterned background. And Image "A" a logo with a transparent
background.
As it stands I have image "A" as a "png" and as you know....
they are fri**ing huge! Haveing it as a "gif" only presents me with
the IE6 problem of it adding a colored background to the image.
So I'm stuck! Can any one tell me or point me in the
difection of a tutorial to tell me the best way to add an image
with a transparent background in Dreamweaver.
Really need some help with this!
Thanks all!

Before going much further I'd recommend reconsidering the use
of a textured background. They are usually included for the benefit
of the site owner only, and likely to annoy visitors. Studies on
the subject suggest they often lead to usability problems. I do
like to header graphic, but at 200K it's kinda heavy and can
probably be optimized.

Need some help with guitar setup...

jeez, never thought i'd be asking a question like this after playing for like 20 years, but i need some help with a guitar setup for mac. i'm gonna list out a lot of crap here that prolly doesn't affect anything at all, but here goes.
Imac 17inch G4 - latest updated OS X... 10.4, or 5, or whatever. garageband 3.0
digitech gnx-3
alesis sr-16
sure mic's
yamaha e203 keyboard
here's the setup:
yamaha is on its own on a usb uno midi interface, sure's connected to gnx's xlr port, alesis connected to gnx's jam-a-long input, '87 kramer vanguard connected to gnx's guitar input. currently running headphones out on gnx to line in on mac.
here's the problem:
everything works beautifully, but my guitar sounds like crap. if i plug headphones into the gnx, it sounds beautiful. that makes me think its some kind of level issue between the gnx's output, and the mac's input, but nothing seems to fix it.
by sounding like crap, i mean way too much bass. sound is muddy, blurry, not crisp... aka crap. i've tried altering both output and input on mac and gnx, and i cant get a combination that works. the gnx has a s/pdif out, can the mac accept that as input? might that help? short of running the gnx to my marshal half stack and mic'ing that, anyone have any suggestions, or use a similar setup?
any help would be greatly appreciated!

anyone? ... any suggestions? I think it might be an issue with the gnx pre-amping the signal as it goes out, and then the mac amping it on the way in, giving me a buttload more signal than i need, but since i cant find a happy level, i'm not really sure. i really dont want to resort to mic'ing my marshall... even with the volume almost off, my jcm900 is WAY too loud for apartment use. its not like i really NEED the guitar to sound perfect, i only use garageband to sketch out ideas for songs between myself and bandmates, but its really annoying to not have my customary crisp distortion. my bass player keeps telling me to use the built in amps, but, not to dis a practically free program, but the built in amps blow, at least after 10 years of marshall tube amplification they do. if anyone has any suggestions that might be helpfull on how i might resolve this, i would be your best friend for life and go to all your birthday parties

Need some help with computation

Hi, I need some help with the following:
My page 3 is a form thats shows, among other things, a document ID (:P3_DOC_ID). Next to this item I have created a button that calls a document selection form (page 10).
On selection this forms sets 2 items:
P10_SELECTED (Y or N)
P10_DOC_ID (the selected documents ID value)
When the user selects a document he returns to the calling form.
On page 3 I now try to capture the selected values. For a test item I managed to do this by defining this items source as:
[PL/SQL function body]
begin
if V('P10_SELECTED') = 'Y'
then
return V('P10_DOC_ID'); -- selected value
else
return V('P3_TEST'); -- else the original value
end if;
end;
However I want P3_DOC_ID to capture the selected value. I tried using a computation but that did not work. Any ideas?
thanks Rene

You might want to check if the "Source Used" attribute for P3_DOC_ID is set to always or to "only when ..." it sounds like you need it set to "only when ..."
If that does not work try this
Place the following in a pl/sql anonymous block and turn off your
computation.
if :P10_SELECTED = 'Y'
then
:P3_DOC_ID := :P10_DOC_ID; -- selected value
else
:P3_DOC_ID := :P3_TEST; -- else the original value
end if;
