How can I run other programs using java program

hi experts,
I am trying to execute a set of commands from java program
eg: from command prompt
java CommandExecutor c:\winnt\notepad.exe c:\some.exe c:\onemorecommand.exe
and inside the CommandExecutor main method..
public static void main(String []arg)
for(i = 0; i < arg.length; i++)
Runtime.getRuntime().exec(arg(i));
the above code is executing all the command one after the other, but I want to execute the above commands squentially, i.e I want to execute the second command only after finishing the first command and the third after finishing the second and so on depending upon the arguments passed, how can I acheive this...
I have tried to use the Process which is returned by the exec(arg) method but the exitValue() returns same value before execution and after execution.
thanks,
krishna

Did you try to get the process returned and then try
process.waitFor() method. This waits for the process to finish.
After that try the next execution

InputStreamReader isr = new InputStreamReader(stream);
BufferedReader br = new BufferedReader(isr);
String line = null;
while ( (line = br.readLine()) != null) .....

How to run the program using specific classpath

Recently I installed Javamail 1.2 and JAF1.0.1 on my NT Box and set up the classpath. I can compile my java email code by using: javac myEmail.java. But when I tried to run the code using java myEmail, it always gives the error: Exception in thread "main" java.lang.NoClassDefFoundError: myEmail.
when I use -verbose and found that it always goes to:
C:\Program Files\JavaSoft\JRE\1.3.1\lib\rt.jar to find classes even I use -cp option to point Javamail\mail.jar and activation.jar.
what is wrong with it? Thank you in advance!!!!!!

What does this have to do with JMS. I suggest that this should have been posted to the Java Programming forum where you would have gotten a quick response as this is a simple problem to diagnose.
The problem is that the class myEmail, which you created, is not on the class path so it cannot find it. It has nothing to do with the location of mail.jar and activation.jar, although this may cause problems later.
What you need to do is check the classpath in the environment variables section of the System dialog box. Make sure it refers to . (the current directory) as well as the locations of mail.jar and activation.jar. Also when you invoke myEmail ensure you are in the same directory.
Hope this helps

How to run a program in java by double clicking on it?

hi,
simple question for you all:
normally when i do java programs i am used to compiling it and running it via JBuilder.
However, i saw a java program that had been installed on a desktop and the user double clicked it and it came straight up.
how can this be done?

You can create executable jar files that can start up an application when double clicked. If you want more specifics, search the forums for "executable jar" and I'm sure you'll get more than enough info.

How to run batch programs using SUBMIT command without any interaction need

Hello ABAP gurus,
I have created a batch program in SE38 which calls many other SE38 Programs (Reports).
I have used the command SUBMIT to call the sub programs. There are about 15 sub programs that this main batch program is calling.
It works fine, but after calling each subprogram it stops and I have to manually click on 'Back Button' in green on the sap screen to run the next program in the list. Like this I have to do 15 times to run all the programs in the batch.
Is there a way to avoid this manual intervention and make the program run all the sub programs on its own.
Your feedback will be highly appreciated.
Thanks
Ram

Thanks Sampath for the response.
Yes I am using the option "AND RETURN". So it is coming out of each sub program, and it is at this stage it waits for me to click on 'backward green arrow' to continue to the next.
Here is the code I have used
SUBMIT Z_AS_BI_F0005_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_DIVISION_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_COMPANY_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_CUSTOMER_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_BRANCH_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_BUS_UNIT_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_ADDRESS_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_CUSTOMER_GROUP_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_GROUP_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_PMT_TERMS_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_REGION_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
SUBMIT Z_AS_BI_TERRITORY_EXTRACT WITH S_DATE IN S_DATE WITH P_TEST = 'N' AND RETURN.
Any other suggestions or feedback will be appreciated.

How to read system eventlog using java program in windows?

How to read system eventlog using java program in windows?
is there any java class available to do this ? or any one having sample code for this?
Your friend Zoe

Hi,
There is no java class for reading event log in windows, so we can do one thing we can use windows system 32 VBS script to read the system log .
The output of this command can be read using java program....
we can use java exec for executing this system32 vbs script.
use the below program and pass the command "eventquery"
plz refer cscript,wscript
import java.io.*;
public class CmdExec {
public static void main(String argv[]) {
try {
String line;
Process p = Runtime.getRuntime().exec("Command");
BufferedReader input =
new BufferedReader
(new InputStreamReader(p.getInputStream()));
while ((line = input.readLine()) != null) {
System.out.println(line);
input.close();
catch (Exception err) {
err.printStackTrace();
This sample program will list all the system log information....
