jschell,
ODBC shell is the odbc.ini or odbcinst.ini? No.
The shell is something that you explicitly installed. Just like you installed Apache, or perl, or a C++ compiler, or even a CD driver.
If yes,
What is the difference between odbc.in and
odbcinst.ini? No idea. But on a windows box those are ini files that specify odbc info. I don't think ini files are going to help on linux.
Which of them will be execute when i
want to establish a connection using "jdbc:odbc:...."
in DriverManager.getConnection?I am rather sure that neither of them would 'execute'
>
Is it MS Access ODBC linux driver is the file like
libodbc.so, libmdbodbc.so, libmdbsql.so and so on?No idea, but I doubt it.
What makes you think that you even have a MS Access ODBC linux driver on your box?
Then, can u tell me which is MS Access ODBC linux
driver or what is the driver file name for MS Access
ODBC linux driver?Nope.
If you installed a MS Access ODBC linux driver, then the ODBC shell will know where it is.
And if you did install such a driver you should post the link where you got it here, because as far as I know, there is no such driver (nor is there one for MS SQL Server.)

Hi.. I found the JDIC binary files. There are different binaries for all the plateform. Is there any solution which is independent of plateform.Yes, and we already told you: Use JDK6, which has those libraries built into the standard class library.
How can I use these binaries in my existing project. does it work, If I place them at same place where other .class files are kept.Read the documentation of the JDIC project. I'm sure they answer this question in their FAQ.

URGENT Creating database in Linux using RMAN dump of windows

Hi Everyone,
I'm having a problem in creating a database in Oracle Enterprise Linux using a database dump of Windows platform.
I Have the following-
-->RMAN Backup (for windows database)
-->Archive log files.
Using these i've to create the same database (clone) in linux.
But when i'm try to do this ,everything goes fine except the datafile structures remain same as in windows( like C:\oracle\datafiles\system.dbf instead of /home/oracle/datafiles/system.dbf)
And also i'm not able to restore the full database.
Please suggest me the way to accomplish the task.

Hello
You posted in the wrong forum, you'd better use one of the database forums : http://forums.oracle.com/forums/category.jspa?categoryID=18
Anaway, regarding your datafile name strucyture you should look after db_file_name_convert in RMAN documentation. As for your other question, please be more precise (which version, what happens, etc).
But again, post in the right forum and you'll get a ton of answers

How to run SQL script file on Linux using Java ?

Hi,
I need to execute .sql file using java. I used following approach for this.
private void runScriptEvent(java.awt.event.ActionEvent evt) {
 String sqlOutput = "";
 String sqlPromptLines="";
 String currentFunctionName = "";
 if(con!=null){
 String userName = jTextField4.getText();
 String password = jPasswordField1.getText();
 String databaseName = jTextField3.getText();
 try {
 String script_location = "";
 ProcessBuilder processBuilder =null;
 Process process = null;
 //File file = new File("C:/ScriptFile");
 File file = new File("./SQL_Script");
 //File file = new File("E:\\install\\SQL_Script");
 if(file.exists()){
 File [] list_files= file.listFiles(new FileFilter() {
 public boolean accept(File f) {
 if (f.getName().toLowerCase().endsWith(".sql"))
 return true;
 return false;
 int count = 0;
 for (int i = 0; i<list_files.length;i++){
 script_location = "@" + list_files.getAbsolutePath();//ORACLE
//currentFunctionName = list_files[i].getName();
StringTokenizer st = new StringTokenizer(list_files[i].getName(), ".");
while(st.hasMoreTokens()) {
currentFunctionName = st.nextToken();
String extention= st.nextToken();
System.out.println("Function Name = "+currentFunctionName + "\t Extention = " + extention);
processBuilder = new ProcessBuilder("sqlplus",userName+"/"+password+"@"+databaseName, script_location); //ORACLE
processBuilder.redirectErrorStream(true);
process = processBuilder.start();
BufferedReader in = new BufferedReader(new InputStreamReader(process.getInputStream()));
String currentLine = null;
while ((currentLine = in.readLine()) != null) {
sqlPromptLines = " "+sqlPromptLines + currentLine +"\n";
count ++;
System.out.println(count+" " + currentLine);
if(currentLine.equalsIgnoreCase("Function created.")){
sqlOutput = "\n" sqlOutput currentFunctionName + " " currentLine"\n" ;
break;
}// end while
in.close();
process.destroy();
}//end for
}//end if file exists
} catch (IOException e1) {
jTextArea1.setText(e1.getMessage());
System.out.println("Script Done");
jTextArea1.append(sqlOutput);
}// end id Connection is not null
Above code working appropriate on Windows but not on Linux.
is there any changes needed ?
Regards,
Ajay

Hi gimbal2,
about code
jTextArea1.setText(e1.getMessage());I am using this code so that the user will be prompted with a message rather than stack trace.
About the issue I am getting on linux i believe its because of following statement.
processBuilder = new ProcessBuilder("sqlplus",userName+"/"+password+"@"+databaseName, script_location); //ORACLERegards,

Trouble creating a database in MySQL using java

Hi all,
I am trying to create a program that connects to MySQL and can create databases, tables etc. I can connect to MySQL using the program but I cannot create a database (however if i create the database with the command line i can create tables in the database).
When I try to create a database i get the error
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown database 'persondatabase'Here is the code:
import java.sql.*;
class Connect {
public Connect() {
public Connection connectToMySQL(String database_name) {
Connection con = null;
try {
   Class.forName("com.mysql.jdbc.Driver").newInstance();
   con = DriverManager.getConnection("jdbc:mysql:///persondatabase", "", "");
catch(ClassNotFoundException e) { System.out.println(e); }
catch(InstantiationException e) { System.out.println(e); }
catch(SQLException e) { System.out.println(e); }
finally {
   return con;
public void createDatabase(String database_name) {
Connection con = null;
Statement stmt = null;
try {
   con = connectToMySQL(null); //connect to mysql but not to any one databases
   con.setAutoCommit(false);
   if(!con.isClosed())
    System.out.println("Connected to MySQL. Creating the Database " + database_name);
   String str = "CREATE DATABASE " + database_name;
   stmt = con.createStatement();
   stmt.executeUpdate(str);
   con.commit();
catch (Exception e2) { }
finally {
   try {
    stmt.close();
    con.close();
   }catch (Exception e3) { }
public void createPersonDetailsTable(String database_name, String table_name) {
Connection con = null;
Statement stmt = null;
try {
   con = connectToMySQL(database_name);
   con.setAutoCommit(false);
   if(!con.isClosed())
    System.out.println("Connected to " + database_name + " creating the table " + table_name);
   String str = "CREATE TABLE " + table_name + "(id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, first_name VARCHAR(25), last_name VARCHAR(25), address VARCHAR(40), suburb VARCHAR(20), state VARCHAR(3), post_code INT(1), contact_number INT(10), email_address VARCHAR(40));";
   stmt = con.createStatement();
   stmt.executeUpdate(str);
   con.commit();
catch (Exception e2) { System.out.println(e2); }
finally {
   try {
    stmt.close();
    con.close();
   }catch (Exception e3) { }
}I am wondering if anyone can see where im going wrong? I am currently connecting with an anon account to MySQL.
Here is the program I am using to test the above:
class ConnectionTester {
public ConnectionTester() {
Connect s = new Connect();
s.createDatabase("PersonDatabase"); //this throws the error
//s.createPersonDetailsTable("PersonDatabase", "PersonDetails");
public static void main(String[] arg) {
ConnectionTester start = new ConnectionTester();
}

you should rethink whether you need to create a database using java. personally i think it's a bad idea. your database should exist and the schema should be ready to go when your app starts. why do you think you need to create one?

Executing WINWORD from both Windows and linux using Java

Dear All,
I have a problem when trying to use Runtime class to execute a winword document. My code is as follows.
Runtime r= Runtime.getRuntime();
try{
r.exec("rundll32"+" "+"url.dll,FileProtocolHandler"+" "+"WINWORD"+ " "+"file://C://welkom.doc");
catch(Exception ex){
System.out.println("Unable to open the doc file:"+ex);
When I execute this swing application with the above, the program is unable to open the specific file. And it says "Problem with the short cut, unable to open the file". When I run the program without the file name, it opens a new doc file.
Attn: what I want to do here is I need to open the winword file from both windows and linux. So I cannot use the relative path of the WINWORD.exe file.
Can anyone help me?
Thanks in advance.
Regards,
Bala

If you take a look at the api, there's an exec(String[]) method. This is the one you should use when calling a command with multiple parameters.
so something like...
String[] cmd = new String[] {"rundll32", "url.dll,FileProtocolHandler", "WINWORD", "file://C://welkom.doc"}
r.exec(cmd);

Archiving File on Shared Folder in Linux using java code

Hi All,
I have a requirement wherein I have to ftp a file (Feed.txt) from windows FTP server to Linux machine1 and archive the same file (with timestamp suffixed on file name like Feed.txt_22April) on Linux Machine2. I am
trying to achieve this through java code. I am able to ftp the file(Feed.txt) from windows ftp server to Linux machine1 /opt/ftproot directory and archiving the same file under /opt/ftproot/archive directory of Linux
Machine1 with timestamp suffixed on file name.
My archiving requirement is still not achieved. So, for that I created a shared folder /temp/shared on Linux Machine2 and mounted the /temp/shared folder of Linux Machine2 on /opt/ftproot/archive folder of
Linux Machine1 using following command:
# mount LinuxMachine2: /temp/shared /opt/ftproot/archive
Note: I have given full permission on both the folders.
Logically, archiving the Feed.txt with timestamp in it name under /opt/ftproot/archive folder should create the file in /temp/shared folder of Linux Machine2. But instead of archiving the file on
/opt/ftproot/archive folder, it archive the file on /opt/ftproot folder.
In my java code, I have specified copyDir as /opt/ftproot and archiveDir as /opt/ftproot/archive.
The code is being run from Linux Machine1 as a schedule task.

- You are connecting to a ftp server. I am guessing you didn't write that.
- Get a flexible ftp client, there are many but make sure it shows you the ftp result codes.
- Figure out how and if the ftp server will do what you want.
If it does do what you want then ftp client will let you do the same thing.
If that ftp server doesn't allow you to do it then you must do one of the following
- Find a different server
- Change the requirements
- Find a way to impose the requirements using a tool in addition to ftp like some command executed through telnet.

How to create a ms-access database at runtime using java

hi, this is ravi kiran,
i have a situation where i need to create a new ms-access database with one table in it at runtime(when user clicks on some button).
i have been searching many sites to know how to do this in java, but i didnot find any thing useful.
plz tell me how to do this in java.
plz help me, its urgent
thanx in advance.

Here's how I did it. Research does help, but sometimes looking at others code does too... You do have to have a dummy file that you made with access though. You can't just make a file file.mdb (it will be corrupt)
     public void createDatabase(String database) throws SQLException{
          try{
               // This file needs to have been created with MS Access
               File dbfile = new File(this.dataBaseDir + "dummy.mdb");
               // This is the new database file being made
               File newFile = new File(this.dataBaseDir + database + ".mdb");
               // Copy all bytes from dummy file to new DB file.
               FileInputStream instream = new FileInputStream(dbfile);
               FileOutputStream ostream = new FileOutputStream(newFile);
               int numBytes = instream.available();
               byte inBytes[] = new byte[numBytes];
               instream.read(inBytes, 0, numBytes);
               ostream.write(inBytes, 0, numBytes);
          catch(FileNotFoundException e) { e.printStackTrace();}
          catch(IOException e) { e.printStackTrace();}
          if(DEBUG) System.out.println("creating the " + database + " database");

I am really stuck and do not know how to solve the problem. I appreciate any help or sample (or just some answers...)
Thanks in Advance.
Best Regards,
Ola Aarthun

Hi,
From your code you are just displaying the object rs. You have to handle the display of each record the way you want it(as a table).
You can find a sample code how to build a table from the result object at the following link
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/bfb1ba90-0201-0010-5e97-bd6a8f5022dc

Hi there - I'm new to Java sound, and can't even get my foot in the door on my Linux system. Even thought my speakers and microphone are fully functional on my system (I can record, playback, etc. using other programs) I cannot get Java to find the microphone, speaker, anything. I've tried calling "AudioSystem.isLineSupported(Port.Info.MICROPHONE)", which returns false, as with all the other Port.Info.... objects.
I'm sure there are no programs using my audio devices (used lsof | grep snd and lsof | grep dsp, then killed the only program that had anything open) and I've tried running my Java program as the super-user too, but to no avail.
One thing I CAN do is get sound from /dev/dsp - I can put this into a byte array and play it back later, but I don't know how to find out what sort of codec it uses, how to merge it with Java sound, or anything like that.
Any help would be much appreciated!
If it makes any difference, I'm using Xubuntu 8.10, and I normally don't use a microphone or flashy surround-sound speakers, so I've not touched the sound system since I installed Linux.

Ports are tricky...and by tricky, I don't mean complicated so much as a pain.
Try using Line.Info objects instead of Port.Info objects and see if you can get any lines.
