Executing batch file from Java stored procedure hang

Dears,
I'm using the following code to execute batch file from Java Stored procedure, which is working fine from Java IDE JDeveloper 10.1.3.4.
public static String runFile(String drive)
String result = "";
String content = "echo off\n" + "vol " + drive + ": | find /i \"Serial Number is\"";
try {
File directory = new File(drive + ":");
File file = File.createTempFile("bb1", ".bat", directory);
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
fw.write(content);
fw.close();
// The next line is the command causing the problem
Process p = Runtime.getRuntime().exec("cmd.exe /c " + file.getPath());
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null)
result += line;
input.close();
file.delete();
result = result.substring( result.lastIndexOf( ' ' )).trim();
} catch (Exception e) {
e.printStackTrace();
result = e.getClass().getName() + " : " + e.getMessage();
return result;
The above code is used in getting the volume of a drive on windows, something like "80EC-C230"
I gave the SYSTEM schema the required privilege to execute the code.
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'java.io.FilePermission', '<<ALL FILES>>', 'read ,write, execute, delete');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
GRANT JAVAUSERPRIV TO SYSTEM;
I have used the following to load the class in Oracle 9ir2 DB:
loadjava -u [system/******@orcl|mailto:system/******@orcl] -v -resolve C:\Server\src\net\dev\Util.java
CREATE FUNCTION A1(drive IN VARCHAR2) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'net.dev.Util.a1(java.lang.String) return java.lang.String';
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
The problem that it hangs when I execute the call to the function (I have indicated the line causing the problem in a comment in the code).
I have seen similar problems on other forums, but no solution posted
[http://oracle.ittoolbox.com/groups/technical-functional/oracle-jdeveloper-l/run-an-exe-file-using-oracle-database-trigger-1567662]
I have posted this in JDeveloper forum ([t-853821]) but suggested to post for forum in DB.
Can anyne help?

Dear Peter,
You are totally right, I got this as mistake copy paste. I'm just having a Java utility for running external files outside Oracle DB, this is the method runFile()
I'm passing it the content of script and names of file to be created on the fly and executed then deleted, sorry for the mistake in creating caller function.
The main point, how I claim that the line in code where creating external process is the problem. I have tried the code with commenting this line and it was working ok, I made this to make sure of the permission required that I need to give to the schema passing security permission problems.
The function script is running perfect if I'm executing vbs script outside Oracle using something like "cscript //NoLogo aaa1.vbs", but when I use the command line the call just never returns to me "cmd.exe /c bb1.bat".
where content of bb1.bat as follows:
echo off
vol C: | find /i "Serial Number is"
The above batch file just get the serial number of hard drive assigned when windows formatted HD.
Same code runs outside Oracle just fine, but inside Oracle doesn't return if I exectued the following:
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
Never returns
Thanks for tracing teh issue to that details ;) hope you coul help.

PROBLEM while using URL in order to open a file from a servlet

Hi,
I am having a problem while trying to open a file from my servlet by using URL connection. Following is my code sample. what happens is when I first run my project it opens the file but after that when I rerun it again and again it sometimes opens it and sometimes not. if it can't open it it gives an error saying "the file is damaged and couldn't be repaired". I don't get any exceptions. if you guys can help me I will appreciate it so much... thanks.
here is my code :
URL url = new URL("http://demobcs.ibm.com:81/test.pdf");
resp.setContentType(getContentType("http://demobcs.ibm.com:81/test.pdf"));
          ServletOutputStream sos = null;
          BufferedInputStream bis = null;
          try {
               sos = resp.getOutputStream();
          } catch (Exception e) {
               System.out.println("exception !!!!");
               e.printStackTrace();
          System.out.println("burada2");
          try {
               byte[] bytes = new byte[4096];
               //bis = new BufferedInputStream(conn.getInputStream());
               DataInputStream in = new DataInputStream(url.openStream());
               //DataInputStream in = new DataInputStream(conn.getInputStream());
               bis = new BufferedInputStream(in);
               int j;
               while ((j = bis.read(bytes, 0, 4096)) != -1) {
                    try {
                         sos.write(bytes, 0, 4096);
                         System.out.println("file is being read ...:");
                    } catch (Exception e) {
                         e.printStackTrace();
               in.close();
               bis.close();
               //sos.close();
          } catch (Exception e) {
               System.out.println("exception :"+e.toString());
               e.printStackTrace();
          }

You are writing (<filesize> mod 4096) bytes of crap at the end of the file. Use your variable j instead for the number of bytes to write in your loop.

Using a thread to write a file from a servlet

Does anyone have some code that can help out my problem:
I am writing a file from a servlet, but the servlet completes and loads another page prior to the file writing to disk being completed.
I have tried using threads to stop the serlvet until the file has been completely written, but I am not experianced using threads properly, and so far have been unsuccesssful.
I would sure appreciate some/any code to reference to overcome this problem.
Thanks to any responses.
Dale

Hi the best idea for you is not to use thread, so that the file processing gets completed before your servlet start doing anything else..
something like this.
public void doGet(     HttpServletRequest request,HttpServletResponse response) throws ServletException, IOException
System.out.println("Called Repo");
BufferedInputStream res = new BufferedInputStream((request.getInputStream()));
     File f= new File("img.jpeg");
     FileOutputStream fo = new FileOutputStream(f);
          byte b[]=new byte[64];
          int line=res.read(b);
while(line!=-1)
     fo.write(b);
     line=res.read(b);
fo.close();
//your remaining processing from here...

How to execute batch file from JSP

hi frens !
i wanna know how to execute batch file from my JSP.i am using exec() method to get call the batch file. but its not working ....plz help
here mine code:-
File F = new File("C:/var.bat");
     try{

}Thanks and Regards
Allwyn

You might improve your chances of getting help if you do two things:
1) Explain what "not working" means.
2) ChangeSystem.out.println(IOEx); to IOEx.printStackTrace(); (in the eventhat is in fact related to "not working").

How to execute .msi files from java program

Hi friends,
i have written a java program which invokes and thereby execute any executable files like .exe and .bat.
So its working fine with .exe and .bat files, but it is not working with .msi files.......can you please help me how can i execute .msi files as well??
public class Executeexe {
     public static void main(String ar[])
          try
          Process p=null;
          Runtime rt=Runtime.getRuntime();
          p=rt.exec("D:\\mysql-essential-5.0.83-win32.msi");
          p.waitFor();
catch(Exception e)
}here is the program

Make sure that the command that's being exec'd works from the cmd line.
Then read this article and do what it says:
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
Then if you still are having problems explain what "...it is not working with .msi files..." really means, and provide a [SSCCE Example program|http://mindprod.com/jgloss/sscce.html]

Executing batch files from websevice using ODI OS Command

Hi,
Is it possible to execute the batch files using odi os command from webservices.
We have developed a webservice, which passess some parameters to one batch file and after that we executing the same batch file in package using odi os command. In opeartor is showing as running, it never ends.
But if we run the same package from designer, it is executing successfully. Also the same web service is working fine for executing non batch scenarios.
what could be the problem??
We got one possible reason for failure...
For executing the batch from web services, we need read and executable permissions on the drive where batch sits.
We are logging into ODI using SUPERVISOR. How to give the permissions to SUPERVISOR as we are having windows authentication.
Edited by: Naveen Suram on Dec 17, 2009 8:07 PM
As a work around, can we use ODIOSCommand instead of OS Command. But it is asking for starting event? Whether both the commands does the same functionality??

From the FAQ:
2. How do you launch an external program on a Microsoft Windows platform from a program developed on the Java [tm] programming language?
The following will launch notepad in Microsoft Windows NT:
Runtime.getRuntime().exec("cmd /c notepad.exe");
To launch a program in Microsoft Windows 95/98 use:
Runtime.getRuntime().exec("c:\\windows\\notepad.exe");
The Runtime class allows interaction between a program and its environment. The first string command instructs the command line interpretor, cmd to open up the calculator application.
The exec() methods do not use a shell; any arguments must have the full pathname to the shell as well as the command itself.
For example, to run a shell on the UNIX� platform, type:
Runtime rt = Runtime.getRuntime();
Process p = rt.exec("/usr/bin/sh -c date");
To run a batch file under Microsoft Windows 95/98:
Process p = rt.exec("command.com /c c:\\mydir\\myfile.bat");
To run a batch file under Microsoft Windows NT:
Process p = rt.exec("cmd /c c:\\mydir\\myfile.bat");
where 'cmd' and 'command.com' are the command-line interpreters for Microsoft Windows machines.
The Runtime.exec() methods might not work effectively for some processes on certain platforms. Special care should be taken with native windowing, daemon, WIN16/DOS process or some shell scripts.

Download any type of files from JSP/Servlet

Hi,
I understood that if I want to download a file from a JSP or a Servlet I have to set the content type to the MIME type of the file itself.
And then I have to set the Content-Disposition to "attachment; filename=\"" + file_name + "\";" if I want the Open/Save window displaied by the browser (otherise the "inline;...").
How can I download a file if I don't know its MIME type? Am I suppose to use the "application/octet-stream" MIMETYPE?
Where can I find documentation and sample code for doing it?
Are there any free packages available to do so?
Thank you very much

Look at http://www.javaworld.com/javaworld/javatips/jw-javatip94.html for the basic method. This article also refers to the RFCs on MIME types which should answer your questions on what type to use for unknown or binary data.

Execute sql file from forms

Hello, how is it possible to execute a sql file from forms without using sqlplus, because we have only the forms runtime on our pc.
We can't use forms_ddl because we have a very big sql script for creating a package.
Please help,
GJ

Strange, whenever I have installed forms I got sqlplus too without asking for it. If it is not installed, wouldn't your best bet be to install it ?

Executing .air file from vc++

The above is working fine.
But my problem is that

I want setup should be run in silent mode so I tried with "-silent" parameter but It did not worked.
My Problem:
1. How to hide the setup screen from user.
2. Because I am hiding the setup screen from user. I want that the destination folder should also be specified by paramaters of ShellExecute command.
Actually I am taking the destination folder in C library. I want my application should be install at the location where my C library wants.
