Ho to execute dbschema command in jsp

hi
i am using informix as database server.In that dbschema is a utility that gives schema of table
This command i have to excecute in jsp but i dont how?

hey. Im actually using servlets and i know this isnt the right forum but i was given this url to come look here as it is similar to something i need.
I just need to execute a batch file that sync's down a load of files and directories from perforce. i dont need to print them or see them i just nned it down so im assuming i will need more than just
Process p = Runtime.getRuntime().exec("C:\\sync.bat");
at the top of my code to run the batch file. does anyone have any idea what else i will need.

Execute Linux Command via JSP

How can I execute Linux commands through a JSP page on a Red Hat Linux 6.1 Machine using Tomcat 3.0
Please Mail your answer
[email protected]

Hi Nick,
Thankx a lot, for suggestion,
I wanted to make a page which gives me a text box to write a command and below it shows the result of that command,
Say , I m in directory "/home/dhiraj"
and I write in command text box : "pwd"
it should give me the currrent path in result , which I can show in form of HTML as Results ,
(may be in a String form..)
same way if I write in command box : "ls -l"
it should Return me (say a String) the directory listing of the current path in result,
I have already tried the Runtime & Process class ,
Runtime rt = Runtime.getRuntime();
Process p =null;
p = rt.exec("command here");
p.waitFor();
it has following problems:
1) This way I m not able to get the result ..
2) I tried to make a zip file via my program it did not threw any exception , but could not execute...
I was confused is it 'coz of permission ( rights problem) or some programmatical error as the same program runs via a Java Class file ..
desperately waiting for ur suggestions

I think you might need the java 'robot' class.
However, a JSP page displayed on a browser is running in a secure enviornment that will probably not let you access the computer its running on. Instead, create a serlvet back on the server that runs the robot class. The servlet will send the data to the jsp page for display. The jsp page can send commands to the servlet which will execute it via its robot class.

Executing javascript command in jsp method

here's the situation....
          I have a jsp page with three buttons at the bottom. One button reads
          "Save and Continue", another reads "Save and Quit" and the third reads
          "Quit". OnClick the page executes a java method that does
          verification for form objects, etc. THe problem here is the only way
          I know to close a window is self.close(); in javascript.
          Does anyone know how I may be able to excecute the method on click and
          then have that method close the window? IS this possible?


No, I was not getting an error, but the file that I was executing was suppose to create two files and the two files were not created.
However, I have since discovered that I needed to have write permission on the directory that I was writing too. So, it is working now, but thanks for responding.

Executing batch File from Jsp

I want to execute a batch file which is located at d:\build from a jsp
I also want to give parameters to batch file.
Actually my batch file is demo.bat and i want to execute this command via jsp
demo Compile dev

in a word - don't. that's not what jsps are for.
you sound confused about where jsps actually run. get client and server straight in your head and then think about it again.

Executing "at" command of UNIX through JSP

Friends,
1. "at" command in UNIX execute Unix command at a scheduled time. 2. For each user there will be a table maintained internally which can be accessed by "at" with "-l" argument.
3. A mail will be sent to the owner with the output of the commands as a message.
I tried to run the "at" command of Unix in JSP, which gets succesfully executed in Oracle 10g App Server container (Installed in Solaris machine). I have tested the successful execution of command with the log file. But I haven't got any mail for the output. If anyone had any idea, please help me.
The code I have wtitten is
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec(new String[] {"sh","-c","at 2115 Dec 7 < /export/home/usr1/abc.sh"});
InputStream stderr = proc.getErrorStream();
InputStreamReader isr = new InputStreamReader(stderr);
BufferedReader br = new BufferedReader(isr);
String line = null;
logger.info("<ERROR>");
while ( (line = br.readLine()) != null)
logger.info(line);
logger.info("</ERROR>");
int exitVal = proc.waitFor();
logger.info("Process exitValue: " + exitVal);
My doubts are:
1. Who is the owner of the output of "at"command, which gets executed under Oracle 10g App Server container?
2. If no one is the owner, then where will the output of "at" command will go?
3. Is there any other way to execute "at" command of UNIX in java program? If so, then please help me.
Thanks in advance.

Nandha Kumar.M

I would imagine the process call out will be under the guise of the process owner of the OC4J instance which executing the call.
Have you seen anything different.

Need help with Telnet command in JSP

Here is the code I have been working on but it will not display the buffer to the page..
String [] cmd1 = {"cmd.exe","/c","telnet hqsun1.xx.xxxxx.com"};
          Process n;
          String T = "" ;
          n = Runtime.getRuntime().exec(cmd1);
          BufferedReader in1 =
          new BufferedReader(new InputStreamReader(
          n.getInputStream()));
          while((T=in1.readLine()) != null)
          out.println(T+"");
Maybe someone has done this before? I am trying to acomplish a telnet net session to the screen with some exicuted commands, because this tool is going to be used to help determine system status when the help desk needs to check on something.
Thanks

I don't want to be discouraging, but I'm not quite sure you've thought the problem through. You say that you'd like to create a web page capable of providing various pieces of information to the help desk, and you suggest ping and the output of various canned telnet commands as examples.
What is preventing the help desk from just executing those commands at the command prompt?
I realize that the people working the help desk are (ahem) there for a reason, but it is really much faster for me to just simply type "ping www.mpalfrey.com" at the prompt, then it is for me to fire up the web browser and wait for a response that way. You will likewise find that it is a lot more convenient to perform diagnosis on remote machines directly from the command prompt.
Uh, it's kind of like giving someone a screwdriver, then saying, "oh wait a second" and making them wear an oven mitt in order to use the screwdriver.
But, if you really want to do it this way, the best thing to do is create a wrapper class that directly calls the system command and captures the output to a stringbuffer. Then your JSP page simply has to clone that wrapper via a new() command and trigger it if you go the singleton route. The code would look something like this...
<%@ import page="com.mpalfrey.shellcommands.ping" %>
<%
   myPing foo = new myPing( request.getParameter( "victim" ) );
   foo.trigger();
%>
Ping results:
<%=foo.results()%>JSP can do a lot of wonderful things, but that doesn't mean you have to do it that way. :)

Trouble trying to execute a binary from jsp

Hello,
I need to make an http request to a Solaris box that will execute a binary that exports data.
I have been connecting to the Solaris machine using putty and executing a command like this:
/usr/prms/prod/bin/exportEngine -f/usr/prms/run/work/exportEngine/input/Export_Params.xml -s09/07/2008 -e09/08/2008Now I need to let this be available to users that need to do this from a web page. I am able to do a simple move command but executing this binary doesn't work. I have been working on this for hours, I tried dropping this command to a perl script and it will execute the move command but not the binary too. I'm afraid this is a permissions issue that jsp will not let a web page execute an arbitrary binary.
The try/catch doesn't throw an exception, is there any other method that I can use to diagnose this? I'm new to jsp and Solaris, if anyone can help that would be great!
Thanks,
Jason
Here is my code so far:
<%
String myErrors = "";
try{
    // This command doesn't work
    //String[] command = {"sh","-c","/usr/prms/prod/bin/exportEngine -f/usr/prms/run/work/exportEngine/input/Export_Params.xml -s09/07/2008 -e09/08/2008"};
    // This test command works
    String[] command = {"sh","-c","mv /usr/prms/http/WebStationEE/supvops/test /usr/prms/http/WebStationEE/supvops/test_renamed"};
    final Process process = Runtime.getRuntime().exec(command);
catch (Exception e){
    myErrors = myErrors + e.getMessage();
%>
<html>
<body>
<%
out.println("myErrors: " + myErrors);
%>
</body>
</html>

It is automatically run daily but about one or two times a week a clerical staff person makes a mistake and the corrected data needs to be manually exported again. I have inherited this job and now I'm told that this needs to be put on a website (which is hosted on a Linux box lol) for the clerical staff to be able to plug in what day that needs to be rebuilt.

Executing two commands at the same time from Runtime.getRuntime

Hi everybody,
I m executing a command of imageMagic from javacode to crop and for changing the quality of image.The code is as below :
String changeQuality = new String("convert " + originalImage
                    + " -crop " + imageWidth + "x" + imageHeight + "+" + imageX
                    + "+" + imageY + " -quality " + quality + " " + finalImage);
               Runtime.getRuntime().exec(changeQuality);
But before going to next page of jsp I want the size of the finalImage. So I m calling a new function from the base file, from which i m calling the above function, for getting the size of image:
public String getSize(String finalImage) {
               proc = Runtime.getRuntime().exec("identify " + finalImage);
As identify cmd gives the size and various values of image but this command is showing the size zero. and if try to read the file then it shows FileNotFoundException.It means the file is not on the server.
What should i do to execute both the command and getting the right result.
Any help is appreciated.
Thanks in advance.

Executing shell commands from Java.

I want to execute shell commands in Java using the Runtime.exec( String ) method.
The method works fine under Linux OS, but under Windows '98 the method didn't work at all!
For example the following call: Runtime.exec( "dir" ) throws an exception showing that the command was not completed. If I replace dir with ls under Linux all is good. What is the problem with the Microsoft Windows '98 ? Is there any solution at my problem ?!
thx in advance!

hey JSarmis,
You can help me... "ls" doesn't work for me on linux.. using Runtime.exec, some commands work, others don't... you may hold the key to what i need? How did u get "ls" to work?

In the first line of the JSP file include the package
<%@page import="BankrecBC4J.*" %>
and call
it this way:from the jsp page
new GoodWindowsExec ("calc"); //
which should open up the calciulator, and should do for other os commands as well.

How to Execute shell commands in OSB

Team,
My Requirement:
I have two sftp servers name ServerA and ServerB. Need to copy files from ServerA and place it on ServerB and change the file permissions to 777 after placing the files.
The user i am connecting to ServerB has the access to override file permissions.
Steps
1. With help of FTP adapter in OSB I am reading files from ServerA and writing on to ServerB -- Completed and is working.
2. How to override file permissions after placing the file ????? -- Yet to implement.
Please suggest me how can i accomodate 2nd step.
Thanks,
Suman V.

If by "execute shell commands" you mean actually
running a shell process (as opposed to just forking
and executing specified programs) then I'd advise
against it. The last thing you want is for the
clients to be running arbitrary commands on the
server. You don't want to make it possible for the
client to run "rm -fr /" on your server.Right.
I was assuming (perhaps with more optimism than is really warranted) that the OP was going to be in complete control of which commands were executed--that there'd be a small, fixed set in response to certain user actions.
