What is the trick to 'exec' UNIX commands from within IDM?

Hellos...
We need to change the permissions of a file which an IDM script writes.
Basically I call this rule to write bytes to a file. The write method works but the exec fails.. I dont see permissions set to "666".
<block trace='true'>
<defvar name='retBuff'/>
<invoke name='writeFileUtf8' class='com.waveset.util.Util'>
<ref>fileName</ref>
<ref>xmlData</ref>
</invoke>
<set name='retBuff'>
<invoke name='exec' class='com.waveset.util.Util'>
<concat>
<s>chmod 666 </s>
<ref>fileName</ref>
</concat>
</invoke>
</set>
</block>
What is the correct method (or any way which works) to run shell commands from within IDM??????

Ok. There is no 'trick' just an appreciation of what is being executed, where.
This rule works. I was foolish in testing it via the BPE.
I start the BPE on my laptop which connects to a UNIX server. Silly me was trying to run a UNIX command on my laptop. oops.
Opening an xwindows session and starting the BPE on UNIX gives the expected results. Not sure when the BPE is finally killed off (we are on IDM 7.1) how does NetBeans handle this situation.

Running unix commands from within a procedure

Oracle 11.1, AIX 6.1
================
A developer would like to know what the commands are to execute from within a procedure to run unix commands on the database server and capture those results back to the procedure for parsing & manipulation.
Thanks.

Don't take this as the correct way to do it, but this is merely 'a' way to do it:
have a db procedure thats executes a db function
create or replace procedure csproc(p_cmd in varchar2)
as
x number;
begin
x:=csfunc(p_cmd);
dbms_output.put_line('x is: '||x);
end;
/The function calls a piece of java to execute the os command and return the return code of the os command
create or replace function csfunc( p_cmd in varchar2) return number
as language java
name 'csclass.RunThis(java.lang.String[]) return integer';
/Here is the java class to run the os command
create or replace and compile java source
named "csclass"
as
import java.io.*;
import java.lang.*;
public class csclass extends Object
public static int RunThis(String[] args)
   Runtime rt = Runtime.getRuntime();
    int        rc = -1;
    try
       Process p = rt.exec(args[0]);
      int bufSize = 4096;
       BufferedInputStream bis =
       new BufferedInputStream(p.getInputStream(), bufSize);
       int len;
       byte buffer[] = new byte[bufSize];
       // Echo back what the program spit out
       while ((len = bis.read(buffer, 0, bufSize)) != -1)
          System.out.write(buffer, 0, len);
       rc = p.waitFor();
    catch (Exception e)
       e.printStackTrace();
       rc = -1;
    finally
       return rc;
/and finally the os command - in this case its a very simple shell script
#!/usr/bin/ksh
echo "Hi" >> /app/oracle/workdir/cs.logwill have to grant privileges to my user 'CS' to run the various os commands
exec dbms_java.grant_permission('CS','java.io.FilePermission','/app/oracle/workdir/cs.ksh','read,execute');
exec dbms_java.grant_permission('CS','java.io.FilePermission','/app/oracle/workdir/cs.log','write');
exec dbms_java.grant_permission('CS','SYS:java.lang.RuntimePermission','*','readFileDescriptor');
exec dbms_java.grant_permission('CS','SYS:java.lang.RuntimePermission','*','writeFileDescriptor');and finally can run the procedure from within the db
set serveroutput on
exec dbms_java.set_output(1000000);
exec csproc('/app/oracle/workdir/cs.ksh');
x is: 0
PL/SQL procedure successfully completed.to prove it works ok the logfile shows an entry:

Permission denied when I execute a unix command from within my java applet.

Hi Gang,
Forgive me if this is not the appropriate forum for this problem. I'm posting this problem on this forum since I got no answers on the other forum I posted on.
I've written a simple java applet that runs a unix command and then displays some information. The applet compiles fine, and runs perfectly from the command line on my unix system.
However, when I point a browser at the applet from my desktop PC I get the following error as taken from the java console:
Exception in thread "AWT-EventQueue-2" java.security.AccessControlException: access denied (java.io.FilePermission <<ALL FILES>> execute)
This is of course the first line in a long line of error messages. It appears that I am not able to execute a command on the unix system through my applet. I know the problem is with trying to execute a unix command since commenting it causes no error in the web browser. This is the command I'm using in java to execute the unix command:
p = Runtime.getRuntime().exec("ps");
Here's the html file on the unix system:
<html>
<head></head>
<body>
<appletcode=G.class height="250" width="400">
Your browser does not support the applet tag.
</applet>
</body>
</html>
I won't list the java code since it is compiling and working on the command line. But, if you want to see it I'll provide it.
I've done quite a bit of research on this and it seems that a great number of people have similar problems reading or executing files through java. I have yet to find a solution to this problem.
Here are some details about my setup:
Server:
HP9000 running HP/UX 11.23
Apache Web Server 2.0.35
Java 1.5
Desktop PC:
Win2K Pro
Internet Explorer 6
Java 1.6
If you have a solution I would be very grateful! This problem is keeping me from writing my application!
thanks!

Is there a way to change the VNC password thru unix command in ARD2?

In a local network, I get access denied errors from macs that have the vnc password different than the Administrative login user password. I needed to change the Admistrator password which I did thru the Unix command in ARD2.
Now.
Is there a way to change the VNC password thru unix command in ARD2?
Example:
remote computer setup
Panther 10.3.9
vnc password - gopher
user ID - testARD with admin rights
user password - backdoor
ARD2 Computer setup
10.4.10
login ID - testARD
password - backdoor
I get the blue icon but get an 'access denied' error.
I change the password from backdoor to gopher.
I get the red with dash icon but, can get access to the computer.
What is going on? Is ARD2 using the VNC resource instead of ARDs resources?

A quick search of Google finds this <http://www.macgeekery.com/tips/cli/settingremote_desktops_vnc_password_interminal>. I have not tested this myself.

The built-in Send UNIX Command templates include 'Login User'

On page 144 of the Administrator's Guide.pdf is the title The built-in Send UNIX Command templates include:
Under Miscellaneous it has as the first command "Login User" however it isn't listed for me.
Upon further investigation I discovered in /Applications/Remote Desktop.app/Contents/Resources/English.lproj/UnixCommandTask.strings on line 75 presetLoginUser = "Login User";
Also noted in the MacEnterprise video 2006-04-18_hres.mov at 00:23:07 it is not listed.
I'm aware of the the scripts capable of doing this, I would just like to know why it is not available in the built-in commands or am I missing something?
Thanks to anyone who can help me answer this question.

No, you're not missing anything. The missing template was reported as a bug (or incorrect documentation) several times, but for some unknown Apple didn't fix the problem, either by including the template (missing perhaps because the script is unreliable with Mac OS X 10.4) or removing the reference from the manual, before ARD 3 was released.

Running Unix Command from WEB-APPLICATION

Hi all,
I want to run unix command from a java-based web application. the basic code part is this ---
public class RunCommand
      public String runIt()
          String s = null, returnString = "";
          Process p=null;
          try
                   Runtime rt = Runtime.getRuntime();
              p = rt.exec("sh testPOC.ksh");
              p.waitFor();
              BufferedReader stdInput = new BufferedReader(new
                   InputStreamReader(p.getInputStream()));
              BufferedReader stdError = new BufferedReader(new
                   InputStreamReader(p.getErrorStream()));
              // read the output from the command
              returnString += "Here is the standard output of the command:<br>";
              while ((s = stdInput.readLine()) != null) {
                  returnString += s;
              // read any errors from the attempted command
              returnString += "Here is the standard error of the command (if any): <br>";
              while ((s = stdError.readLine()) != null) {
                  returnString += s;
          catch (IOException e)
              returnString += "exception happened - here's what I know: ";
              returnString += "error-> " + e.getMessage();
          catch(Exception e)
            returnString += "exception happened - here's what I know: ";
              returnString += "error-> " + e.getMessage();
          return returnString;
}this class is kept as an inner class. The control comes to its outer class, from servlet, from which the runit() is called. but the exception is occuring at line of p=rt.exec(.....). it tells "<command name> : not found transaction completed" [got this using getMessage() method].
i am unable to show(and see, too) the stacktrace, because i don't have access to that test environment and its log. i can't run this in local because its windows one.
now can anyone tell me, where is the problem. is there any limitation in web application server/container? this was successful when i used command prompt writing a .java file. Please help me. Thanks in advance...

Friends, i've got, where the problem is.
when we run a class file directly from a command prompt, we get an environment with that shell window. but for a servlet application running these kind of commands from a class creates kind of child processes. each and every command is executed as a child process of jvm and don't get those environment. we have 'PATH' variable in the environment. when a command (say, 'dir' or 'sh' or 'ls', etc.) is executed, the shell first search for that executable file (i.e. dir / sh / ls) in the given paths in the variable 'PATH'. this is not available for the child commands of jvm. hence the basic commands are searched in the current directory of the jvm and they are failed.
i solved the problem giving full path of the commands. like :
p = rt.exec("/bin/sh runningScript.ksh")

Execute unix commands from Java

Hi,
I have a client application running on windows. This client should connect to a unix server and check for the existence of a file and display the result as "File found/File not found". In order to connect from windows to the unix server, I used the sockets and the connection is successfully established. The second part is to check for the presence of the file in unix server. I searched in google.com and the option I found to execute a unix command from java is the "Runtime.exec()". Runtime.exec is considered as the less effective (not a favorable) one.
Is there any other option available (other than the Runtime) to execute the unix command from java? Can you please let me know.
Thanks a lot
Aishu

So, please let me know how I can execute the above unix commands without Runtime.exec()You have a client and a server.
You want something to run on the server, not the client.
That means that something must in fact being running on the server before the client does anything at all.
For example telnet. Or a J2EE server application.
So is something like that running?
If not then there absolutely no way to do what you want, even with Runtime.exec().
If yes then what you do depends on what is running. So Runtime.exec() would be pointless if a J2EE server was running.

Call an interactive UNIX command from java

Hi,
I want to call a UNIX command from java. When issue the command 'htpasswd -c filename username' on UNIX terminal, it asks for the new password and the then confirmation password again (yeah, unfortunately the htpasswd installed on our system does not allow you proivde the password on the command line. So have to work interactively ). Now, I have written a simple java program RunCommand.java. I am hardcoding the password for the htpasswd command in the file (in the real situation, password will be generated dynamically). I want to issue 'java RunCommand' on the UNIX command line and get back the command prompt without being asked for the password twice. The code is below, but the Outputstream does not work as expected. It always asks for inputs. Any idea? Many thanks.
import java.io.*;
public class RunCommand {
public static void main(String args[]) throws Exception {
String s = null;
try {
String cmd = "htpasswd -c filename username ";
// run a Unix command
Process p = Runtime.getRuntime().exec(cmd);
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
OutputStream stdOut = p.getOutputStream();
String pswd = "mypassword";
while ((s = stdInput.readLine()) != null) {
     s = stdInput.readLine();
     stdOut.write(pswd.getBytes());
     stdOut.flush();
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null) {
System.out.println(s);
stdOut.close();
stdInput.close();
stdError.close();
System.exit(0);
catch (IOException e) {
System.out.println("exceptions caught: ");
e.printStackTrace();
System.exit(-1);

There are only about 9 billion responses a day on how to do this. Use the search feature.

text_io.put_line (v_arqlog, v_txt);
text_io.fclose (v_arqlog);
SRW.SET_AFTER_FORM_HTML(SRW.FILE_ESCAPE, :p_file);
rt := RUNTIME.GetRuntime();
proc := RUNTIME.exec(rt,'rm ' || :p_file);
return (TRUE);
end;
The problem is that there isn't a "synchronize" command, and the
RUNTIME.exec(rt,'rm ' || :p_file) don't works (it does nothing) because
the SRW.SET_AFTER_FORM_HTML has a large delay and the following
command is ignored.
How can I solve it?
thanks,
lmprestes
