Launch Acrobat Reader with Runtime.exec() under WINNT4, without absolut pat

Hi,
I would like to launch Acrobat Reader from a Swing application. This works fine with Runtime.exec() as long as I provide the full path to the AcroRd32.exe. The problem is that I cannot predict the location of this exe on the systems of the users. Athough is in the Windows PATH, since I can launch from the windows execute-dialog, the Runtime.exec() is not able to locate the file.
How can I solve this problem?
Thanks a lot!
Horst

hey BIJ, thank you so much man. start really does wonders!! i was stuck with invoking a fortran program for last couple of days and now i went through your postings and tried with start. it did work!!
thanks again,

Problem with Runtime.exec()

Hi,
I'm having a problem with Runtime.exec() . I have a batch file with debug option to FTP the desktop file to mainframe. When I executed this in Windows it's shows me the responce from the server (like ' Transfer Completed' ) for my FTP commands. But when I launch this through java it's only shows the errors not the normal responces from the server. I need this responses to confirm the proper transfer of file.
My Java Code:
String strCommand = "cmd.exe /c " + outdirectory + batchfilename;
boolean bWait = true;
Runtime r = Runtime.getRuntime();
Process pr = r.exec(strCommand);
BufferedInputStream bis =new BufferedInputStream(pr.getInputStream ());
int c=0;
/** Outlet for IO for the process **/
while (c!=-1) {
c=bis.read();
/**Now wait for the process to get finished **/
if(bWait == true){
pr.waitFor();
pr.destroy();
My Batch file is :
FTP -n -d -s:C:\IT2.cmd > C:\tIT2.log
EXIT
Thanks
Sathiesh

Ahh, you are redirecting the standard out from the ftp command to a file, therefore no output is sendt back to your java code,
you have to redirect the stderr stream, not the stdout stream in your batch file;
FTP -n -d -s:C:\IT2.cmd 2> C:\tIT2.log(notice the "2>" instead of ">")
Now your batch file should direct the error stream to the log, and the standard output back to the java program.
(I'm used to UNIX streams, not NT, but the "2>" redirection should work on NT also I guess)

Killing Internet Browser opened with Runtime.exec

I am running Win NT 4.0 and I am successfully opening my HTML help using the following code:
String command = new String("cmd /K ");
command = command.concat("G:\editor\help\index.html");
Process p = Runtime.getRuntime().exec(command);
However, if I run p.destroy(), the browser window does not close. This means that the help remains open after the program exits and also that multiple help windows can be opened.
Does anyone know how to kill a browser opened with Runtime.exec()?
Thanks for any help you can offer,

Thanks jmschrei,
I tried System.exit(0) and Runtime.getRuntime().exit(0) and neither succeeded in closing the internet browser process. I suspect that process.destroy() and runtime.exit(0) both are killing the instance of the command interpreter spawned by runtime.exec("cmd /K URL") and not actually the browser opened by that command. Therefore, I think that the process refers to the "cmd" and not the browser, which probably opens completely independently of my Java program, thus can't be closed by it.
Unforetunately, I don't know another way to open a browser.
If anyone has any additional suggestions, I would appreciate it. Many people in the forums seem to have asked this one, and there are no solutions I could find.

Launch Command Line Scanner with Runtime.exec()

Hi im trying to develop all the process of a common Antivirus ,
I have a command line anti-virus. But when i try to scan a single file mi code doesnt work.
I made the following code:
Runtime runtime = Runtime.getRuntime();
commands = new String[] {"cmd.exe", "/c","C:\\KAVCLineScanner\\kavecscan.exe","C:\\anfed\\a.txt"};
Process p =runtime.exec(commands);
BufferedReader b =new BufferedReader(new
InputStreamReader(p.getInputStream()));
String line=null;
while( (line=b.readLine())!=null){
System.out.println(line);
I think the problem is my parameter where i send the file to scan "C:\\anfed\\a.txt", because if i execute this instruction from MSDOS, the process doesnt have problems.
I also made a .bat file with the instructions but i have the same problem :(
Thanks for any advise

I think java naming is from programmer's point of view, so the output stream of the process would be the inputstream to the programmer, hence I am trying to write to my outputstream, which is actually the process' inputstream.

Error in opening a file with name in chinese characters with Runtime.exec

The issue at hand is when I try to open a file with file name containing chinese characters in a localized environment in Windows through the following java code:
Runtime.exec("rundll32 SHELL32.DLL,ShellExec_RunDLL {File_With_FileName_containing_Chinese_character}");
the following error is thrown by windows.
Cannot open file "C:\??.txt".
with the exception

When I try to use the same command (shown below) from the Windows Run command, the file opens sucessfully
rundll32 SHELL32.DLL,ShellExec_RunDLL {File_With_FileName_containing_Chinese_character}
Please suggest.
Thanks in advance

This may be a file association problem. To solve that:
In Windows 7:
1. Right-click the file,
2. Select "Open With"
select [Your Program Here]
3. Check always use this program.
In Windows XP:
1. Locate the file as you have described above
2. Right click the file
3. Select Open with from the pop-up menu
4. Click Choose default program…
5. Select Excel in the Recommended Programs box
6. Check Always use the selected program to open this kind of file
7. Click on OK.
1. Make Excel not available from Office 2007 listed under Programs and Features in Control Panel.
2. Take a registry backup using the steps given here
3. In the registry editor window expand HKEY_CLASSES_ROOT and navigate to .xls right and delete it.
4. Exit Registry Editor
5. Undo Step 1 to make Excel available.
6. Restart the computer and verify it the issue is fixed.

Runtime.exec() under a specific user account ???

Hi there,
I cann't figure out how to run a script on Unix under a specific user account using the Runtime.exec(). Currently whoever run the java program, the script is ran under that user account.
The code is like:
public class javarun {
public static void main(String[] arg) {
String str = "myunixscript";
// check the arg[1] to decide the appropriate environment.
Runtime r = Runtime.getRuntime();
try {
Process pr = r.exec(str);
pr.waitFor();
int exitstatus = pr.exitValue();
} catch (...) {...}
We have two user accounts: unixusr1 and unixusr2. Now I need to have unixusr1 run the java program ( ie. unixusr1$ java javarun), while the "myunixscript" be executed under unixusr2. One further step is to the unix account name as a parameter so the unixscript could be run under different account.
Any help will be highly appreciated. Thanks.
Edward.

I'm not sure if I have a solution, but here are some questions:
a) have you tried writing additional input to the OutputStream of the process? Although I have not tried it, I would imagine that Process.getOutputStream() exists for commands that require the invoking resource to send additional input to the process- like an su command that requires a password check.
b) can you just write a shell script that takes the needed information as an argument. That is, write a shell script that takes the username and password as an argument and then you can use Runtime like,
Runtime.exec("myScript", new String[] { "hisId", "hisPasswd" });Obviously, you would need to think through the security concerns of such a script, but, if it complies with the security structure of your environment, it might allow you to avoid the problem by using the shell script to invoke the destination command with the proper UID and password, rather then using the JVM to invoke it. Basically, the script becomes a proxy for the JVM to invoke that command.

Any problem with Runtime.exec()

I am required to launch a local exe from an applet. At present I am using AppletContext.showDocument().The problem with this is that in netscape a box is popped up forcing the user to save that exe file. The requirwment is to run it directly without any message being asked.
A workaround is to use Runtime.exec(), it works, however I have heard that it is not platform independent.
(1) Is there a better solution than Runtime.exec() ?
(2) If not could you give me some info on Runtime.exec() and the problems associated with it ?
(3) Is there a way to use AppletContext.showDocument() without the message being asked ?
Shikari.

First of all, Java is platform independent language, and has many security restriction in it's applets.
so from an applet you can't excute a program using "Runtime.getRuntime().exec()".
coz. there is security restriction on that.
for the "AppletContext.showDocument()" this methid is for displaying the specified document on the client browser, so it can't excute a client program.
if u need to use Runtime.getRuntime().exec() you have to get the client agreement for that.
see the applet security restriction for more info.

Color saturation problem in Acrobat Reader 7.0.9 under Linux

Hi,
I'm working with a guy who is producing PDFs of my work with Indesign.
Using acrobat reader under Linux (version 7.0.1 and also 7.0.9), the colours in these PDFs always appear very saturated. This is a big problem for me because I cannot see with the reference viewer the results of PDFs to be sent to print.
I tried the same pdf file under OS X & Windows, it appears OK with Acrobat reader. Other free pdf readers under Linux also show the right colours (but not always the transparency ;-).
Does anybody has an idea to help me?
@Adobe people: in case you want to test, I drop a copy of my PDF file at: http://cardot.net/files/pdfcolours.pdf (2.24 MB)
Thanks in advance
Jean-Christophe Cardot

We are able to reproduce color saturation problem at our end. We have noted down and will work on this.
Thanks.

Problems with Runtime.exec inside OC4J in OAS!!! help!!

Hi all,
I have a method on my webapplication and the same call a script .cmd on windows and a .sh on unix using Runtime.exec command, inside this script have a call to a java program ie.
java JMSAdmin < jcajms.txt
OK, this is fine in OC4J Standalone 10.1.3 in windows and linux but in OAS 10.1.3 the same not run and not throw any error. Its is a BUG ?? limitation ?? OAS ignore a call to another java ??
please help.
Tanks

Normally, you must prepend the command with a call to the command shell (eg /bin/sh).
But I suspect that this call isn't allowed due to Java EE specification restrictions.

Why are you posting hundreds of lines of code not related to the problem??? 99.9% of the code you posted has absolutely nothing to do with using the Runtime.exec() method.
Create a simple test program that simply tries to invoke the Runtime.exec() method. Once you get that working, then you incoporate it into you real program. Don't clutter the forum with unnecessary code.
public class WindowsFileProtocolHandler
     public static void main(String[] args)
          throws Exception
          String[] cmd = new String[4];
          cmd[0] = "cmd.exe";
          cmd[1] = "/C";
          cmd[2] = "java";
          cmd[3] = "YourClassHere";
          Process process = Runtime.getRuntime().exec( cmd );
}

Intermittent Error with Runtime.exec()

I have a Windows Service for an Adaptive Server Anywhere database server that is built upon install of our application.
One of the new things we're trying to do with our app
requires us to shutdown this service using Java (1.4.2_06) code. This
shutdown is done by using the runtime.exec("dbsvc -x
ASA_SERVICE") command. Sometimes this works fine, but
others it fails. I got the error output from the java
command which is: Overlapped I/O operation is in progress.
Error stopping service "ASA_SERVICE". When I try and
shutdown the service via the Windows Service dialog I have
no problems anytime. I see no errors in the ASA log
file. Can someone tell me what might be
causing the error sometimes when running this using the Java
runtime.exec(...) command?
Thanks,
Cory Musselman

Try running the command a couple of dozen times from the command line, not from Runtime.exec() but just from a plain old command line. That should give you a better idea of whether Runtime.exec() is part of the problem or not.

Issue with Runtime.exec() or ProcessBuilder pb.start()

I am having problem with running a separate JVM process. The finished code must be able to start and forcibly stop the spawned process. The problem I am having is that the spawned process seems to hang. I have tried reading all output from the process with no luck. The java program opens a ServerSocket on a separate thread right away. However, when this is started through Runtime.exec() or ProcessBuilder the socket does not open until the first process is terminated. I have have been looking high and low for an answer that will fix this. I could write this all as a multithreaded application, however I would really like to isolate the second process in terms of the JVM settings. I would like to be able to monitor this process directly and indirectly for failure or early termination and restart it automatically. Other Java program I run with this method experience the same problem--a hang at a variable point in execution that is not relieved until the originating process ends.
        try {
            ProcessBuilder pb = new ProcessBuilder("\"C:\\Program Files\\Java\\jre6\\bin\\java.exe\" -jar -server \"PATHTOJAR\"");
            Process p = pb.start();
            java.io.InputStream is = p.getInputStream();
            while(running) System.out.print(is.read());
        catch (java.io.IOException ioe) { ioe.printStackTrace(); }

The finished code must be able to start and forcibly stop the spawned process.Process.destroy().
I have tried reading all output from the process with no luck.No you haven't - see below.
The java program opens a ServerSocket on a separate thread right away. However, when this is started through Runtime.exec() or ProcessBuilder the socket does not open until the first process is terminated.Which of these programs is which?
ProcessBuilder pb = new ProcessBuilder("\"C:\\Program Files\\Java\\jre6\\bin\\java.exe\" -jar -server \"PATHTOJAR\"");That should be
ProcessBuilder pb = new ProcessBuilder("C:\\Program Files\\Java\\jre6\\bin\\java.exe", "-jar", "PATHTOJAR", "-server");
java.io.InputStream is = p.getInputStream();
while(running) System.out.print(is.read());(a) call ProcessBuilder.redirectErrorStream(true);
(b) the loop must stop when is.read() returns -1, and you shouldn't print that value.

Launch Acrobat Reader 8 not-maximized

I have a flex 3 app (not AIR) for which I am launching the
acrobat reader 8 with a pdf that the user selects from a tree
control. The code looks like....
var pdfUrl:URLRequest = new URLRequest("
http://server/pdftest/1.pdf");
navigateToURL(pdfUrl,"_blank");
I have set the Internet options in the Adobe Acrobat Reader
to not launch in the browser. The problem is that every time the
reader launches it is maximized....is there a way to launch it so
that it is not maximized (even if it will use its last window size
would be good).
Thanks

Acrobat/Reader 9 were the first version to incorporate AES-256 code, so if you want to remain backwards compatible with Reader 7 or 8 you need to continue to use AES-128. I believe this is documented in the help for the section that describes how policy edit works.
