You should use CallableStatement.
import java.sql.*;
class StoreProc
public static void main (String args [])
throws SQLException {
try {
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn =DriverManager.getConnection ("jdbc:oracle:thin:@testing:1521:test1", "scott", "tiger");
//create procedure and call it in java (testproc)
CallableStatement cstmt = conn.prepareCall("{call testproc(?,?)}");
cstmt.setString(1, "teststore");
(2, "testagain");
cstmt.executeUpdate();
cstmt .close();
conn.close();
catch(SQLException e)
System.out.println("SQLException caught: " + e.getMessage()+" "+e.getErrorCode());
null

How to do this

hello kylas

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".
Good Luck

How to execute a script(.sql) file from a PL\SQL procedure

I would like to know how to execute a .sql file from a stored procedure and the result of it should update a table. My .sql file contains select statements.

Hi!
just go through the following piece of code -
SQL> ed
Wrote file afiedt.buf
1 declare
2    str varchar2(200);
3 begin
4    str := '@C:\RND\Oracle\Misc\b.sql';
5    execute immediate(str);
6* end;
SQL> /
declare
ERROR at line 1:
ORA-00900: invalid SQL statement
ORA-06512: at line 5ORA-00900: invalid SQL statement
Cause: The statement is not recognized as a valid SQL statement. This error can occur if the Procedural Option is not installed and a SQL statement is issued that requires this option (for example, a CREATE PROCEDURE statement). You can determine if the Procedural Option is installed by starting SQL*Plus. If the PL/SQL banner is not displayed, then the option is not installed.
Action: Correct the syntax or install the Procedural Option.

Let me guess, you want your web application to run a program on the client and to your surprise that's not working?
Ain't gonna happen.
its taking more time to execute .... that's y is there any other option to execute .exe file other than Runtime.getRuntime().exec("filename");Write proper English and you may be taken more seriously.
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
3) whenever you start thinking of executing external programs from Java, start thinking of not using Java in the first place.

How to execute external spawned process using java

Hi,
I am executing PGP from command line using java.
For adding the public key I use Runtime object like this
Runtime rt = Runtime.getRuntime();
Process process = rt.exec("pgp -ka "+"d:/Mangesh/pubkey/sandy.asc "+"C:/PROGRA~1/NETWOR~1/PGPNT/keyrings/pubring.pkr");PGP is executing this but inbetween it asked for confirmation "Do you want to add public key (y/n)"
I am providing data to process this way:
PrintWriter pw = new PrintWriter(new OutputStreamWriter( process.getOutputStream()));
pw.write('y');
pw.flush();But after this their is no execution from PGP and console remains until I closed it.
PGP is waiting for ENTER KEY
How can I provide ENTER KEY from java
This is right method ??? or any other options are available??
I am awaiting for your valuable suggestions .
Regards
Man479

On Windows the "enter key" consists of two characters: carriage return and a line feed (\r\n). You may have to send both. If that doesn't work, pgp is not reading the reply through stdin, only through the console, and there's no way to pass the 'y' to it through Java.

How to execute any cmd command from java application?

Hi all,
How to execute or call any command of cmd from java application??
Is there any method to do so??
Or, is it possible to do it using Runtime.exec() ??? And if so, how to use it, please explain with ab example...

Thank you.

If google would be the best option, then I would not be on Sun's forums and I would not have asked experts like you, sir !! :-)
Neway, I got the solution from PhHein !!

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.

How to execute procedure in SQL Worksheet ?

Hi, anybody know, how I can execute procedure here?
I try EXEC sec_roles, EXEC security_admin.sec_roles, EXECUTE - there is a SQL statement error. When I use CALL - there is no such procedure (I have execute previleges).
Although in SQLPlus EXEC works, but there are problems with standard SQL commands (all of them returns "2" no matter what content is).
Any ideas?
Regards
Krzysztof

exec procedure(parameters) is a sql plus (and a few others) shortcut for
BEGIN
procedure(parameters);
END;So try that then pressing/clicking whatever it is in sql worksheet that makes a statement run.
Note that if your procedure has parameters defined as OUT or IN OUT, you will need to supply a variable to accept the returned value(s).

How to execute unix command from the Java program running on Windows

Hello,
I need to
1. Execute a unix shell script from a Java program running on the Windows.
2. I also need to capture the output of this shell script in my program.
Please suggest me how to achieve this.
Thanks in Advance.

Hi...
Something is missing here
If you want to execute a shell script in windows that not posible unless you find or develop a unix shell script parser for windows.
But if you are trying the execute a unix shell script on a remote unix computer from your java program running on a windows platform you can do that by logging on to the UNIX terminal which is running on port 23 I think.
You can test this using telnet tool on windows
just type on command prompt
telnet <ip of the unix pc> <port number this case 23>
you should get the unix terminal. If that works you can do the same through java or you can directly conect to port 23 of that pc using sockets that way your program will be platform independant

How to execute a Unix Command in java

Hi, Iam trying to execute a unix command on Sun Solaris by passing that command to a java program. How can I achieve this?
Thanks in advance.

Have a look at the javadoc around the Runtime.exec() method. If the command is a shell command then you might have to execute a shell as well as the command.
For example, if you wanted to run a unix command 'ls -l > output.txt' the you might have to pass the following string into the exec() method,
"/bin/sh ls -l > output.txt'

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.
Kind Regards,
