Error while trying to execute a unix shell script from java program
Hi
I have written a program to execute a unix shell script in a remote machine. I am using J2ssh libraries to estabilish the session connection with the remote box.The program is successfully able to connect and authenticate with the box.
The runtime .exec() is been implemented to execute the shell script.I have given below the code snippet.
try {
File file_location = new File("/usr/bin/");
String file_location1 = "/opt/app/Hyperion/scripts/daily";
String a_mib_name = "test.sh";
String cmd[] = new String[] {"/usr/bin/bash", file_location1, a_mib_name};
Runtime rtime = Runtime.getRuntime();
Process p = rtime.exec(cmd, null, file_location);
System.out.println( "Connected to the server1" );
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = br.readLine();
while(line !=null)
System.out.println(line);
line = br.readLine();
br.close();
p.getErrorStream ().close ();
p.getOutputStream().close();
int retVal = p.waitFor();
System.out.println("wait " + retVal);
//session.executeCommand("ls");
catch (IOException ex) {
I get an error message
Connected to the server
java.io.IOException: Cannot run program "/usr/bin/bash" (in directory "\usr\bin"

I am sure of the file path where the bash.sh and test.sh are located.
Am i missing something? Any help would be greatly appreciated.
Thanks
SenthilHi, I am using a simple program to connect to a RMI server and execute shell script. I use the Runtime.exec aommand to do the same.
The script is sh /tmp/pub/alka/test.sh /tmp/pub/alka/abc/xyz/ul ul
The script when run from the server, gives no errors. But when ran using rthe above method in java, gives errors as follows,
Mycode:

Is it possible to execute SAPGUI scripts from java program?
Hi everyone..
I need to develop an java applications that executes the SAPGUI script or any technique that execute set of transaction as client.
Is it possible to execute SAPGUI scripts from java program? if so, how it can be achieved? is there any other technique to achieve above mention scenario?.
it will be more helpful, if docs related to that are shared..
Thanks in advanceOh, bummer. Would be much more convenient if I could just use iTunes for everything. Can't stand WMP. I wonder if WinAmp might be a good compromise?

Execute ConcurrentRequest from java program
In order to execute concurrent request from java program are this 3 lines enough :
1)ConcurrentRequest concurrentrequest = new ConcurrentRequest(oadbtransaction.getJdbcConnection());
2)int i = concurrentrequest.submitRequest("some value", " some value", "some value", null, false, vector);
3)oadbtransaction.commit();
*******************************8
I am asking because while executing ConcRequest from PL/SQL I have to call a functin : fnd_global.apps_initialize(user_id ,resp_id, app_id) prior to executing FND_REQUEST.SUBMIT_REQUEST.
Is there any equivalent in java for apps_initialize?
thanks in advance.hi
u can call the FND_global using callable statement
DBTransaction txn = getDBTransaction();
CallableStatement cs =
txn.createCallableStatement("begin fnd_global.apps_initialize(:1, :2,:3);end;");
try
cs.setString(1, getOADBTransaction().getUserId() );
cs.setString(2, getOADBTransaction().responsibilityId());
cs.setString(3, getOADBTransaction().getApplicationID());
cs.execute();
cs.close();
catch (SQLException sqle)
try { cs.close } catch (Exception(e) {}
throw OAException.wrapperException(sqle);

Problem while running dos command from java program
Dear friends,
I need to terminate a running jar file from my java program which is running in the windows os.
For that i have an dos command to find process id of java program and kill by using tskill command.
Command to find process id is,
wmic /output:ProcessList.txt process where "name='java.exe'" get commandline,processid
This command gives the ProcessList.txt file and it contains the processid. I have to read this file to find the processid.
when i execute this command in dos prompt, it gives the processid in the ProcessList.txt file. But when i execute the same command in java program it keeps running mode only.
Code to run this command is,
public class KillProcess {
public static void main(String args[]) {
KillProcess kProcess = new KillProcess();
kProcess.getRunningProcess();
kProcess = new KillProcess();
kProcess.readProcessFile();
public void getRunningProcess() {
String cmd = "wmic /output:ProcessList.txt process where \"name='java.exe'\" get commandline,processid";
try {
Runtime run = Runtime.getRuntime();
Process process = run.exec(cmd);
int i = process.waitFor();
String s = null;
if(i==0) {
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(process.getInputStream()));
while ((s = stdInput.readLine()) != null) {
System.out.println("--> "+s);
} else {
BufferedReader stdError = new BufferedReader(new
InputStreamReader(process.getErrorStream()));
while ((s = stdError.readLine()) != null) {
System.out.println("====> "+ s);
System.out.println("Running process End....");
} catch(Exception e) {
e.printStackTrace();
public String readProcessFile() {
System.out.println("Read Process File...");
File file = null;
FileInputStream fis = null;
BufferedReader br = null;
String pixieLoc = "";
try {
file = new File("ProcessList.txt");
if (file.exists() && file.length() > 0) {
fis = new FileInputStream(file);
br = new BufferedReader(new InputStreamReader(fis, "UTF-16"));
String line;
while((line = br.readLine()) != null) {
System.out.println(line);
} else {
System.out.println("No such file");
} catch (Exception e) {
e.printStackTrace();
return pixieLoc;
} when i remove the process.waitFor(), then while reading the ProcessList.txt file, it says "No such file".
if i give process.waitFor(), then it's in running mode and program is not completed.
Colud anyone please tell me how to handle this situation?
or Is there anyother way to kill the one running process in windows from java program?
Thanks in advance,

errorGobbler.start();
outputGobbler.start();
// any error???
int exitVal = proc.waitFor();
System.out.println("ExitValue: " + exitVal);
} catch (Throwable t)
t.printStackTrace();
}when i execute the above code, i got output as,
Execing cmd.exe /C wmic process where "name='java.exe'" get commandline,processid
and keeps in running mode only.
If i execute the same command in dos prompt,
CommandLine
ProcessId
java -classpath ./../lib/StartApp.jar;./../lib; com.abc.middle.startapp.StartAPP 2468
If i modify the command as,
cmd.exe /C wmic process where "name='java.exe'" get commandline,processid > 123.txt
and keeps in running mode only.
If i open the file when program in running mode, no contents in that file.
If i terminte the program and if i open the file, then i find the processid in that file.
Can you help me to solve this issue? -

SOLVED: How To Use LDAP over SSL (no certs) from java program
Trying to connect to OID from Java program (using Grocery Store demo as a test). Want to use SSL with no server certificate. OID is configured, and ldapsearch -U 1 works.
Tried using URL with ldaps, or adding SECURITY_PROTOCOL,"ssl". In both case the error is 'simple bind failed'.
Samples on OTN say this should be possible, but then only have code for the non-ssl connection.
Posting from others with this same question don't seem to have been answered.
Message was edited by:
user590350
I have found that using ConnectionUtil.getSSLDirCtx() from Oracle will make a no-authentication SSL connection. An example in the sample code would be useful.Even with Java APIs, There is a way to talk through SSL without bothering about certificates. It's just that you will have to write some code and make some changes in settings.
Read following to get further information on the same.
http://kiranthakkar.blogspot.com/2007/04/dummny-certificate-authentication.html
I don't know or I won't comment whether it's the right approach or not but it's definitely a work around.

Execute a Linux konsole command from Java
Hy,I am having problems when trying to execute a command for konsole from java.
This is a part of my code
try {
Runtime.getRuntime().exec("konsole");
catch (IOException ex) {ex.printStackTrace();}this code opens the Linux konsole ; is the a method to append a command for Linux from java??
ThanksOK
this is what I am trying to do : by pressing a button
in a JFrame I want to start Snort (the exact command
is snort -c /etc/snort/snort.conf )
What I want is the following: I press that button
and the Konsole in Linux opens and that command to
be executed I would just use the Process.getInputStream() method to retrieve what Snort said and display that in a JTextArea or something... why bother launching it in a terminal?
I don't know if Snort is a daemon or what... if it's a daemon, you're not going to get much output from it... it'll fork itself into the background and exit.
If it isn't a daemon, then you can either just redirect the output to a file, a la:
konsole snort /etc/snort/snort.conf > /tmp/snort.outand do a "tail" sort of monitoring on the file. You could also just keep that process up in a different thread, and use a timer to periodically update the output into a JTextArea (this would also allow you to be notified when the process ended). Finally, you could wrap your command in a script and execute it that way.
Maybe you are looking for
