Capturing verbose output from javac??

I am tyring to capture the verbose output from javac.
From a UNIX shell, I type "javac -verbose Test.java 2> dump.txt" and it works fine.
The trick is that I want to do this within a Java program. I have the following code, but I can't seem to find a solution. Any help is appreciated.
import java.io.*;
public class GetTree {
public static void main(String[] args) {
     try {
     Runtime r = Runtime.getRuntime();
     String options = "-verbose";
     // The java file to compile.
     String fileName = args[0];
     String command = "javac " + options + " " + fileName + " 2>dump.txt";
// This doesn't even create the 'dump.txt' file!?
     Process p = r.exec(command);
     catch (Exception e) {
     System.err.println(e);
-----------------------------------------------------------------------

How to capture graphical outputs from other programs

Does anyone know how we capture the graphical outputs from the other programs and show them
on the swing?
I'd like to use a java program to run gnuplot, capture the outputs, and show them using swing.

Depends on what you mean by "graphic outputs".
Taking a quick glance at the gnuplot homepage, it looks as if you can output to PNG files, so just run the app, and load the png file.

You can set the MIME content type as .doc and try to open the Page.
res.setContentType("application/vnd.ms-excel"); to generate the Page output as Excel
res.setContentType("application/vnd.ms-word"); to generate the Page output as MS Word doc
Hope this helps..

I want write the message generate by script into concurrent log's. is possible ?
Thanks

Hi,
Append the message you want to the log file of the concurrent request - you have control over the command called by the preprocess script already.

Redirecting output from plink

I am currently trying to write a function that runs plink and captures the output from that process. When I try StandardOutput I get nothing and when I try StandardError I get "Unable to read from standard input: The handle is invalid." I can only assume that this means I am trying to read while plink is waiting for input. I am also passing my command via a text file called apCommands.txt. When I run this command manually it works and gives me the required output, I just can't figure out why I can't redirect that output so I can store it in a results file. Here is the code I have right now.
string pArgs = "-m \"" + ABSPATH + "\\apCommands.txt\" -ssh myHost -l user -pw password";
string output;
if (File.Exists(ABSPATH + "\\apTest.txt"))
File.Delete(ABSPATH + "\\apTest.txt");
StreamWriter apTest = new StreamWriter(ABSPATH + "\\apTest.txt");
Process runAP = new Process();
ProcessStartInfo apInfoStart = new ProcessStartInfo(ABSPATH + "\\plink.exe");
apInfoStart.Arguments = pArgs;
apInfoStart.RedirectStandardOutput = true;
apInfoStart.CreateNoWindow = true;
apInfoStart.UseShellExecute = false;
runAP.StartInfo = apInfoStart;
runAP.Start();
output = runAP.StandardOutput.ReadToEnd();
runAP.WaitForExit();
apTest.WriteLine("Standard Output");
apTest.WriteLine(output);
apTest.Close();
runAP.Close();
Thanks,
Joe

I see. I wasn't aware that it wasn't a reliable way to connect to ssh. As for the error message that was from standardError. I think the process may have been waiting for input when I was trying to read from StandardOutput and thats why I got that error message. Also instead of redirecting StandardOutput I tried redirecting the output directly into a file by running a cmd process and passing the commands I wanted to run through StandardInput. The underlined section is all I changed besides running this inside of a cmd process. This did work for me but I would rather know how to do it using StandardOutput.
string dArgs = "cd \"" + ABSPATH + "\"";
string pArgs = "plink -ssh myHost -m \"" + ABSPATH + "\\apCommands\" -l user -pw password > test.out";
Process runAP = new Process();
ProcessStartInfo apInfoStart = new ProcessStartInfo("cmd");
//apInfoStart.Arguments = pArgs;
apInfoStart.RedirectStandardInput = true;
apInfoStart.RedirectStandardOutput = true;
apInfoStart.CreateNoWindow = true;
apInfoStart.UseShellExecute = false;
runAP.StartInfo = apInfoStart;
runAP.Start();
runAP.StandardInput.WriteLine(dArgs);
runAP.StandardInput.WriteLine(pArgs);
I haven't tried reading the StandardOutput from this piece of code, but I will probably try it.
Thanks,
Joe

Capturing Program Output

I have a program in which I want to capture the output generated when I run the class. The function is off in another java file that I have imported into this one. Some of the code is below.
Tester controllerTester = new Tester();
controllerTester.runtest(testArray);
runtest outputs information via System.out.println and I am wanting to capture that information. How do I go about doing this? I have sucessfully captured output in another program that executes an external program with the Process p = Runtime.getRuntime().exec(program) command. I just need to know how to capture the output from runtest above. Any help would be appreciated.
Thanks...Chris

Runtime.getRuntime().exec(program) command. I just
need to know how to capture the output from runtest
above. Any help would be appreciated.[url http://java.sun.com/j2se/1.5.0/docs/api/java/lang/System.html#setOut(java.io.PrintStream)]System.setOut(PrintStream) might be of help. Though it'll capture any output to system out, not only that produced by the method you mention (no problem if the code is executed in a single-threaded environment).

Capturing output from Runtime.exec()

I want to be able to get the jvm version by calling "java.exe -version" from within a java application. The following code executes fine (given all the stuff I left out of this post) except for the fact that the inputstream only reads null from the process.
Anybody have any ideas of why I can't capture the output? This same code works fine if I execute a bat file which calls "java -version".
final private String[] versionInfo ={"cmd","/c","\"C:\\Program Files\\java\\bin\\java\"", "-version"};
try{
               //execute new process
               System.out.println("executing process");
               Runtime runtime = Runtime.getRuntime();
               Process proc = runtime.exec(cmd,env);
               System.out.println("initializing streams");
               //read output
               InputStream inputstream = proc.getInputStream();
               InputStreamReader inputstreamreader = new InputStreamReader(inputstream);
               BufferedReader bufferedreader =     new BufferedReader(inputstreamreader);
               String line;
               System.out.println("reading output");
               while ((line = bufferedreader.readLine())!= null){
                    System.out.println("read something");
                    System.out.println(line);
                    outputText.append(line);
                    outputText.append("\r\n");
                    outputText.update();
               System.out.println("finished reading");
               //check for errors
               try {
                    if (proc.waitFor() != 0) {
                         System.err.println("exit value = " + proc.exitValue());
               }catch (InterruptedException e) {
                    System.err.println(e);
          }catch(Exception e){
               e.printStackTrace();

Where do I find output from verbose:class?

I want to find out where a class is being loaded from. So, using the config tool, I have added "-verbose:class" to the server's Java parameters and restarted. However, I cannot find the logging file that contains the expected output from enabling this option. What file do I look in? It's not in server0/log/defaultTrace.trc nor server0/kernel/classload/default.trc.

hi,
the following link gives u the details about the usage of verbose:class.. its an extract from a book..
it opens only if you a g-mail account.. if u don have i can send u an invite

Unable to output from FCP to Canon XL1.

I have an eMac with Final Cut Pro 4.5 HD. I also have a Canon XL1 3 CCD camcorder.
I have no problem capturing footage from my camcorder to my eMac on FCP. I can also connect my Canon to my VCR and record off my camcorder to my TV, as well as play the tape on my camcorder to watch it on TV.
However, I cannot output from FCP to my camcorder. The 4 to 6 FireWire is attached to both the camera and the eMac and I checked the Log and Capture feature and FCP does recognize a camera or deck is attached. I've been trying to output it using manual record in which I press record on my camcorder and play the playhead on FCP. As I record, there is no picture on my viewfinder, nor any audio being recorded and when I play it back, I just get this blank blue screen, but the timecode is recorded.
Am I missing something here?

ensure the following are set
View>Video Playback>Firewire Apple 720x480 (NTSC or PAL - whatever is appropriate)
View>Audio Playback>Audio follows video
View>External Video>All Frames
If this isn't what you are set to do, you won't be sending video out to your recorder.

Hi Abhay,
      If you go to Transaction code SE93, enter the tcode "CK86_99" and click display, you may see the default value for transaction is "KKBB" and the screen field for P_SCREEN = 0300, P_TCODE = ck86_99.
      You may need to copy the transaction code "KKBB" and go to SE93 again, enter the tcode for "KKBB" then click display, now you may see the program name is "RKKB1000".
      Hope this answer your question.
Thanks

How can I connect my svideo output from my camcorder to my Macbook pro retina?

How cn I connect the s video output from my camcorder to my 13" macbook pro retina?

Buy a video to USB converter.
Buy a more expensive video to Firewire converter (it may give better quality).
Find an older mini DV camera with 'video in' to make transfers to tape to capture from.
