How to execute an external file in java ?

How to execute an external file , where the file name of the external file is in unicode character. (i,e, may be in Chinese character).

Process p = Runtime.getRuntime().exec("/path/to/executable");
This is write. But my question is while the file name is in Chinese font.
It means while a file name is in Chinese font or any unicode character that are supported by window but not in the command prompt. In this case the file name is changed to ??????.doc like.
So, while trying to execute this it shows File not found message.

1) it's not "taking more time to execute", whatever that's supposed to mean.
2) there's no other way to execute something. Not that you should every use even that way anyway

How to execute a .cmd file in java

I can execute an .bat or a .exe file.
But .cmd file is not getting executed in java.
Pls tell me how to do this

You can solve this problem by using the following method:
private String[] getEnvironmentVariables() {
    final Map<String, String> env = System.getenv();
    final String[] result = new String[env.size()];
    final StringBuilder buf = new StringBuilder(100);
    int i = 0;
    for (Entry<String, String> e : env.entrySet()) {
      buf.setLength(0);
      result[i++] = buf.append(e.getKey()).append('=').append(e.getValue()).toString();
    return result;
}You just have to execute your command like this now:
Runtime.exec("cmd /C " + getMyCommand(), getEnvironmentVariables(), getMyExecDirectory());The reason why "start" didn't work is, that it is a command executed in a shell, thus you need "cmd /C" to execute start in the cmd. So you can do this as well:
Runtime.exec("cmd /C start " + getMyCommand(), getEnvironmentVariables(), getMyExecDirectory());If you want to to execute "myCommand" in an own process.

HOw to create a Batch file for java application and whats the use of this ?

HI,
How to create a Batch file for java application ?
And whats the use of creating batch file ?
Thanks in advance

First of all, you're OT.
Second, you can find this everywhere in the net.
If you got a manifest declaring main class (an classpath if needed), just create a file named whatever.bat, within same directory of jar file, containing:
javaw -jar ./WhateverTheNameOfYourJarIs.jar %*By the way, assuming a Windows OS, you can just double click the jar file (no batch is needed).
Otherwise use:
javaw -cp listOfJarsAndDirectoriesSeparedBySemiColon country/company/application/package/className %*Where 'country/company/application/package/' just stands for a package path using '/' as separator instead of '.'
Don't specify the .class extension.
Javaw only works on Windows (you asked for batch, I assumed .BAT, no .sh), in Linux please use java.exe (path may be needed, Windows doesn't need it 'cause java's executables are copied to system32 folder in order to be always available, see PATH environment variable if you don't know what I'm talking about) and use ':' as classpath (cp) separator.
The '%***' tail is there in order to pass all parameters, it only works on Windows, refer to your shell docs for other OSs (something like $* may work).
This way you have a command you can call to launch your code (instead of opening NetBeans just to see your app working). You could schedule tasks on it or just call it in any command prompt (hope you know what it is 'cause there have been people in this very same forum with no clue about it, if not just hold the 'Windows button' and press 'R', then type 'cmd' and run it).
Finally add dukes and give 'hem away.
Bye.

Executing mysql script file in java

Hello,
I am working on a research project that involves the creation of anywhere from 50 to 200 MySQL databases at a time. So far I am able to execute CREATE DATABASE commands successfully using the Statement.execute() command.
So onto my problem.....
I have the script files needed to create the tables for each database, but I cannot figure out how to run them through java. I am trying to execute a SOURCE /file_location/ statement, but I am getting "you have an error in your mysql syntax....".
Does anyone know if there is a way to execute a script file from java?

How to execute a SELECT statement in java??

How to do this

hello kylas
actually i didnt get why this program example?? wats
its executing ??? Look at reply #3 in your other thread:
http://forum.java.sun.com/thread.jspa?threadID=713289&messageID=4126346
Notice the similarity? You've now asked "How to delete a record in Java" and "how to execute a select statement in java". You may have noticed that, aside from the SQL and the call to execute and executeUpdate (for delete) it's the same code. This is because you don't so much do these things in Java, you do them in SQL. The Java code simply asks the Driver to execute whatever SQL you write. So, I really hope your next post isn't "how do I execute an UPDATE statement in Java".

Hi,
You can make an executable jar file such that when you double click on that it starts running. Just follow the steps.
1. Open a notepad and write the following
Main-Class: XXXXXXXX
XXXXXXX means Your Main Class name. Don't forget to press Enter after you write your class name.
2. Save the file as Mani.mf
3. In the commant prompt ( your directory ) type following lines.
jar cmf Mani.mf Demo.jar *.*
4. This will make a jar file which is executable jar file
Hope this will help you.

How to read a text file using Java

Guys,
Good day!
Please help me how to read a text file using Java and create/convert that text file into XML.
Thanks and God Bless.
Regards,
I-Talk

     public void fileRead(){
             File aFile =new File("myFile.txt");
         BufferedReader input = null;
         try {
           input = new BufferedReader( new FileReader(aFile) );
           String line = null;
           while (( line = input.readLine()) != null){
         catch (FileNotFoundException ex) {
           ex.printStackTrace();
         catch (IOException ex){
           ex.printStackTrace();
     }This code is to read a text file. But there is no such thing that will convert your text file to xml file. You have to have a defined XML format. Then you can read your data from text files and insert them inside your xml text. Or you may like to read xml tags from text files and insert your own data. The file format of .txt and .xml is far too different.

How to execute a .sql file from a batch file

Hi all
I've to take backup of a database weekly twice on every wednesday & Friday @ 5pm IST. I've written a hot backup script, which works every well.
now i want to automate the script. ie i want this script to run on wednesday & friday @ 5pm without any human interfearance ie with out actually any1 executing this script.
i created a batch file prod.bak with the following lines
@echo off
set oracle_sid=testdb
set oracle_home=d:\oracle\ora92
sqlplus /nolog
connect sys as sysdba/oracletest@testdb
this batch file when eexecuted connects me to sql prompt.
Now i want to execute my backup script bkp.sql automatically when it is connected to sql prompt.
(i tried with these lines in the above batch file...
call bkp.sql---it just opens the bkp.sql file in notepad & displays the script
start bkp.sql---same as call
connect / as sysdba/pwd@[email protected] --- does not work simply remains a the sql prompt.
At 17:00 /Every:w,f "d:\bkp.sql"---does not work simply remains at the sql promt.)
Can any1 let me know what should i write in the batch file that will execute the bkp.sql file automatically after it gets connected to sql prompt. M using oracle 9i.
I'll manage he time through windows utility of scheduling task.. Let me know how to execute the .sql file from a batch file.
Thanks
Tripti

Try
sqlplus "sys/oracletest as sysdba" @bpk.sql
Working locally, and having set the ORACLE_SID, you don't need to specify the SqlNet alias (@testdb).
Remember to put an exit at the end of the bpk.sql script.
