How to get and disply dynamic values on the fly and display in applet

hello all ,
i have a problem in refreshing a applet.
i have a scrolling applet which will get the share values from the database and display in a scrolling applet in the browser . i am getting the values and displaying it.
but the problem is , if i enter a new record in the database, until and unless i press refresh button of the browser, i am not getting the new values . please help me if anybody having the idea. please mail me to [email protected]
thank you all.

You want a database update to trigger an applet refresh? Can't be done.
However, you can have the applet periodically re-query the database and update its display with the information it retrieves. Just kick off a Thread that sleeps for a bit, wakes up, queries the db, updates the display, and goes back to sleep.

How to get system Environment variable?

How to get system Environment variable without using jni?
just like "JAVA_HOME" or "PATH"...
Any reply is help to me!! :-)

Thx for your reply...
I get it!!!
Read environment variables from an application
Start the JVM with the "-D" switch to pass properties to the application and read them with the System.getProperty() method. SET myvar=Hello world
SET myothervar=nothing
java -Dmyvar="%myvar%" -Dmyothervar="%myothervar%" myClass
then in myClass String myvar = System.getProperty("myvar");
String myothervar = System.getProperty("myothervar");
This is useful when using a JAVA program as a CGI.
(DOS bat file acting as a CGI) java -DREQUEST_METHOD="%REQUEST_METHOD%"
-DQUERY_STRING="%QUERY_STRING%"
javaCGI
If you don't know in advance, the name of the variable to be passed to the JVM, then there is no 100% Java way to retrieve them.
NOTE: JDK1.5 provides a way to achieve this, see this HowTo.
One approach (not the easiest one), is to use a JNI call to fetch the variables, see this HowTo.
A more low-tech way, is to launch the appropriate call to the operating system and capture the output. The following snippet puts all environment variables in a Properties class and display the value the TEMP variable. import java.io.*;
import java.util.*;
public class ReadEnv {
public static Properties getEnvVars() throws Throwable {
Process p = null;
Properties envVars = new Properties();
Runtime r = Runtime.getRuntime();
String OS = System.getProperty("os.name").toLowerCase();
// System.out.println(OS);
if (OS.indexOf("windows 9") > -1) {
p = r.exec( "command.com /c set" );
else if ( (OS.indexOf("nt") > -1)
|| (OS.indexOf("windows 2000") > -1 )
|| (OS.indexOf("windows xp") > -1) ) {
// thanks to JuanFran for the xp fix!
p = r.exec( "cmd.exe /c set" );
else {
// our last hope, we assume Unix (thanks to H. Ware for the fix)
p = r.exec( "env" );
BufferedReader br = new BufferedReader
( new InputStreamReader( p.getInputStream() ) );
String line;
while( (line = br.readLine()) != null ) {
int idx = line.indexOf( '=' );
String key = line.substring( 0, idx );
String value = line.substring( idx+1 );
envVars.setProperty( key, value );
// System.out.println( key + " = " + value );
return envVars;
public static void main(String args[]) {
try {
Properties p = ReadEnv.getEnvVars();
System.out.println("the current value of TEMP is : " +
p.getProperty("TEMP"));
catch (Throwable e) {
e.printStackTrace();
Thanks to W.Rijnders for the W2K fix.
An update from Van Ly :
I found that, on Windows 2003 server, the property value for "os.name" is actually "windows 2003." So either that has to be added to the bunch of tests or just relax the comparison strings a bit: else if ( (OS.indexOf("nt") > -1)
|| (OS.indexOf("windows 2000") > -1 )
|| (OS.indexOf("windows 2003") > -1 ) // works but is quite specific to 2003
|| (OS.indexOf("windows xp") > -1) ) {
else if ( (OS.indexOf("nt") > -1)
|| (OS.indexOf("windows 20") > -1 ) // probably is better since no other OS would return "windows" anyway
|| (OS.indexOf("windows xp") > -1) ) {
I started with "windows 200" but thought "what the hell" and made it "windows 20" to lengthen its longivity. You could push it further and use "windows 2," I suppose. The only thing to watch out for is to not overlap with "windows 9."
On Windows, pre-JDK 1.2 JVM has trouble reading the Output stream directly from the SET command, it never returns. Here 2 ways to bypass this behaviour.
First, instead of calling directly the SET command, we use a BAT file, after the SET command we print a known string. Then, in Java, when we read this known string, we exit from loop. [env.bat]
@set
@echo **end
[java]
if (OS.indexOf("windows") > -1) {
p = r.exec( "env.bat" );
while( (line = br.readLine()) != null ) {
if (line.indexOf("**end")>-1) break;
int idx = line.indexOf( '=' );
String key = line.substring( 0, idx );
String value = line.substring( idx+1 );
hash.put( key, value );
System.out.println( key + " = " + value );
The other solution is to send the result of the SET command to file and then read the file from Java. ...
if (OS.indexOf("windows 9") > -1) {
p = r.exec( "command.com /c set > envvar.txt" );
else if ( (OS.indexOf("nt") > -1)
|| (OS.indexOf("windows 2000") > -1
|| (OS.indexOf("windows xp") > -1) ) {
// thanks to JuanFran for the xp fix!
p = r.exec( "cmd.exe /c set > envvar.txt" );
// then read back the file
Properties p = new Properties();
p.load(new FileInputStream("envvar.txt"));
Thanks to JP Daviau
// UNIX
public Properties getEnvironment() throws java.io.IOException {
Properties env = new Properties();
env.load(Runtime.getRuntime().exec("env").getInputStream());
return env;
Properties env = getEnvironment();
String myEnvVar = env.get("MYENV_VAR");
To read only one variable : // NT version , adaptation for other OS is left as an exercise...
Process p = Runtime.getRuntime().exec("cmd.exe /c echo %MYVAR%");
BufferedReader br = new BufferedReader
( new InputStreamReader( p.getInputStream() ) );
String myvar = br.readLine();
System.out.println(myvar);
Java's System properties contains some useful informations about the environment, for example, the TEMP and PATH environment variables (on Windows). public class ShowSome {
public static void main(String args[]){
System.out.println("TEMP : " + System.getProperty("java.io.tmpdir"));
System.out.println("PATH : " + System.getProperty("java.library.path"));
System.out.println("CLASSPATH : " + System.getProperty("java.class.path"));
System.out.println("SYSTEM DIR : " +
System.getProperty("user.home")); // ex. c:\windows on Win9x system
System.out.println("CURRENT DIR: " + System.getProperty("user.dir"));
Here some tips from H. Ware about the PATH on different OS.
PATH is not quite the same as library path. In unixes, they are completely different---the libraries typically have their own directories. System.out.println("the current value of PATH is: {" +
p.getProperty("PATH")+"}");
System.out.println("LIBPATH: {" +
System.getProperty("java.library.path")+"}");
gives the current value of PATH is:
{/home/hware/bin:/usr/local/bin:/usr/xpg4/bin:/opt/SUNWspro/bin:/usr/ccs/bin:
/usr/ucb:/bin:/usr/bin:/home/hware/linux-bin:/usr/openwin/bin/:/usr/games/:

How to get system idle time

Hello Sir,
I am Udhaya. I don't know how to capture system idle time using java. Please any one help me how to get system idle time. Any class is available in java to get idle time?

the moment you ask the system for its idle time that idle time becomes 0, so just returning a constant value of 0 would always yield the correct answer.But when you don't call this constant method the value it would return is wrong. This is the sort of thing that keeps me up at night.Except of course that when you don't call it it doesn't return it and therefore still behaves properly.
Or were you thinking of philosphical problems like "what does a method do when it's not called?"?Actually I was trying to see if I could get the OP to say boo to a goose.

How to get system status and user status ?

how to get system status and user status for the given production order?
In which PP table we can
find these?
Thanks&Regards
Satish

Hi Ram,
Use the FM "STATUS_READ" to read both the system and user statuses for an Order.
Alternatively, the following tables store the user and system status info:
JSTO- Status object information
JEST- Individual Object Status
Hope this helps.
Let me know if u need further information.

[ASK] How to get system date and substring / concate in data manager dynami

Hello guys.
I want to run package DM with the input have default value.
The selection is look like this :
Dimension : CATEGORY
Source : PLAN_2011
Destination : FORECAST_2011
Dimension : TIME
Source : 2011.JAN,2011.FEB,2011.MAR,2011.APR,2011.MAY,2011.JUN,2011.JUL,2011.AUG,2011.SEP,2011.OCT,2011.NOV,2011.DEC
Destination : <same>
How to get system date year and do the substring / concate ?
So dimension category source will be PLAN_<YYYY>, destination = FORECAST_<YYYY>
Dimension source = <YYYY>.JAN,<YYYY>.FEB,<YYYY>.MAR,<YYYY>.APR,<YYYY>.MAY,<YYYY>.JUN,<YYYY>.JUL,<YYYY>.AUG,<YYYY>.SEP,<YYYY>.OCT,<YYYY>.NOV,<YYYY>.DEC
Depend on year system date.
Thank you.

Stuart,How are you storing OnSaleDate. If you are using OnSaleDate as an attribute dimension then you can write a Custom Defined Function to either:1- query your system for the current date and return the number of seconds that have elapsed since 1/1/1970. This is by definition the begining of the Epoch and how Essbase treats Attribute Dimensions of the Date type.public static long getDateInSeconds() { Calendar cal = Calendar.getInstance(); return cal.getTime().getTime()/1000;}2- Write a Custom Defined Function that will accept the OnSaleDate and return the number of days sincepublic static double daysSince(double myDate) { return (getDateInSeconds()-myDate )/86400;}

How to get system date and time?

Can someone show me a code on how to get system date and time.
Thanks!

there is one really easy way to get system time, the api gives a great example of code on this. use gregorian calendar, which you'll find in the api under GregorianCalendar. You only need to create one instance of GC, ie Calendar time = new GregorianCalendar();
you save seconds, minute and hours into int values, so you don't have to access the system time every second, you can create a thread which adds one to the int second value, if oyu see what i mean, for example, i have saved the hours, minutes and seconds as int values;
int hour, minute, second;
i can then create a thread (Thread thread = new Thread(this) and run it like:
Calendar time;
int hour, minute, second;
Thread thread = null;
public MyTime() {
hour= time.get(Calendar.HOUR_OF_DAY);
minute = time.get(Calendar.MINUTE);
second = time.get(Calendar.SECOND);
if(thread == null) {
thread = new Thread(this);
thread.start();
public void run() {
Thread t = Thread.currentThread();
while(thread == t) {
thread.sleep(1000);
second++;
if(second > 59)
minute++;
if(minute>59)
hour++;
formatTime();
public void formatTime() {
second = (second > 59? 0 : second);
minute = (minute > 59? 0 : minute);
hour = (hour > 23? 0 : hour);
System.out.println(hour+":"+minute+":"+second);
public static void main(String[] args) {
new MyTime();
I know this looks like gibberish but it should work. If not, try to fix the problem, i have written from memory really but i guarantee you, this gets the time then every second, simply adds one to the second and then formats time. You can also access the day, month and year then format them using the above code. I don't like giving code since you should really do these things yourself but it is 2:04am, i have nothing better to do and i am not tired so i did you a favour - i have become what i always did not want to, someone ho stays upall night writing code.

How to find out web-inf path from the physical drive?

How to find out web-inf path from the physical drive?
I have some user profiles in web-inf directory.SO I want to know the path from root directory like
d:/program files/allaire/jrun/appname/web-inf/profiles/username like that.
Presently I am able to get the path upto the application directory and from that I am concatinationg web-inf/profiles/username .
But it is giving problems when it is deployed under unix or linux.Because web-inf there it treats as WEB_INF
SO I want to get the path of web-inf directory with out hard coding.
Thanku

String path = application.getRealPath("/WEB-INF/profiles/username");
Note sure why you need this, but you don't need the real path to read the file - you can get an InputStream using the relative path. See ServletContext getResource() and getResourceAsStream().

How to get an better screen-update? The view on the remote Mac is nearly static.

You can try reducing the bit depth of the screen image via the slider in the upper-right of the Control window. If that doesn't help, you may just not have a sufficiently fast network connection to correctly handle the data transfer necessary. This is often the case if you're connecting across the Internet. What is your network speed between the administration system and the client?

How to get online apps to work with the Verizon DSL modem firewall set at "Medium" level, not "Low?"

How to get online apps to work with the Verizon DSL modem firewall set at “Medium” level? Xbox 360 Live, FTP, and the Windows sntp Time checker native to Windows XP WON’T WORK unless the Verizon firewall is first reset down to “Low.” Then all works well, but I then risk low firewall protection. Setup: · Westell 6100 DSL modem (Software Version: VER:4.04.03.00 Transceiver Revision: 7.2.3.0 Model Name: C90-610015-06), · D-Link DIR-655 wireless router (Hardware Version: A3, Firmware Version: 1.21), For Xbox 360 Live the “canned” port forwarding rule for provided in Verizon’s drop-down list for the Westell 6100 modem forwards ports 88 and 3074 for both TCP and UDP. This does not meet Microsoft’s forwarding recommendations for Xbox 360 Live stated at http://support.microsoft.com/kb/908874. Instead, for the Verizon modem (Westell) I made a new port forwarding rule to comply with those Microsoft instructions. It forwards ports 53, 80 and 3074 for TCP and ports 53, 88 and 3074 for UDP. These same ports are also forwarded in the D-Link router configuration. For FTP, port 21 is also forwarded for TCP and UDP in both modem and router. But they don’t work until I first cripple the Verizon firewall down to “Low.” How to get them to work with the Verizon firewall up to Medium?

While I do not know the answer to your question, BUT since you have this modem and another router - you could just follow.
