About java.lang.Process class?

hi, i am executing one batch file (it contains 2 executable statements) through java.lang.Runtime class exec method like this..Process p1=r.exec("cmd /K start .\\Skeletons\\reports\\FormatFiles\\"+strDTab+".bat");.. i want to get the output of this process is it success, failure or suspect?. how to use the waitFor() method of Process class in this situation?. and also the execution of the batch program will give some status (if fail it will throw some exception), i want to catch the status. depending on the status i will decide proceed to further statements or not?..

You use waitFor() by calling it on the process you get back from the exec()
If you want examples use google to find them.

Java.lang.Process.exec()

I have read a article about the "java.lang.Process.exec()" (url:http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html)
Having some questions with the example in it.
The example code:
import java.util.*;
import java.io.*;
public class BadExecJavac
    public static void main(String args[])
        try
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec("javac");
            //int exitVal = proc.exitValue();
            int exitVal = proc.waitFor();
            System.out.println("Process exitValue: " + exitVal);
        } catch (Throwable t)
            t.printStackTrace();
}The process can run but never complete.
Why? Just because when invoke the javac.exe without any argument,it will product a set of usage statements that describe how to run the program and the meaning of all the available program options.So the process is in deadlock.
The question is, when i change the exec("javac") to exec("javac a.java"), in which the "a.java" is not exist, so the jvm should product error:
error: cannot read: a.java
1 error
But after i changed the code and run the class, at this time the process can run and complete.
The two codes both product some statements,but why the first one never complete,but the second did. Why?

import java.util.*;
import java.io.*;
public class A
    public static void main(String args[])
        try
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec("javac");
            InputStream is = proc.getErrorStream();
            int i=0;
            while ((i = is.read()) != -1)
                System.out.print((char)i);
            // int exitVal = proc.exitValue();
            // int exitVal = proc.waitFor();
            // System.out.println("Process exitValue: " + exitVal);
        } catch (Throwable t)
            t.printStackTrace();
}usng this modification, i could see some error messages.
because exec(cmd) executes the command in a separate process, it will not display the results on the current console. If you want see the results, you should use getInputStream() and getErrorStream().
good luch ^^

Get complete output from java.lang.Process

How do I get the complete output from java.lang.Process?
By the time I've started reading from Process.getInputStream() the process has already terminated...

I solved the problem:
private int exec(String pArguments[], OutputStream pOut, OutputStream pErr) throws IOException {
     class ProcessOutputPrinter implements Runnable {
          private InputStream ivIn;
          private OutputStream ivOut;
          public ProcessOutputPrinter(InputStream pIn, OutputStream pOut) {
               ivIn = pIn;
               ivOut = pOut;
          public void run() {
               try {
                    for(int tByte; (tByte = ivIn.read()) != -1; ) {
                         ivOut.write(tByte);
                    ivOut.flush();
               catch(IOException e) {
                    e.printStackTrace();
     // Start process
     Process tProcess = Runtime.getRuntime().exec(pArguments);
     // Create out printer
     Thread tOutPrinter = new Thread(new ProcessOutputPrinter(tProcess.getInputStream(), pOut), "NamingAdmin out-printer");
     tOutPrinter.start();
     // Create err printer
     Thread tErrPrinter = new Thread(new ProcessOutputPrinter(tProcess.getErrorStream(), pErr), "NamingAdmin err-printer");
     tErrPrinter.start();
     // Wait for process and printers to finish
     try {
          tProcess.waitFor();
          tOutPrinter.join();
          tErrPrinter.join();
     catch(InterruptedException e) {
     // return process exit value
     return tProcess.exitValue();

Error: invalid file 'java/lang/Object.class' (wrong version: 48, expected 45)
anyone has any idea abt this.
im stuck :( pls help.

Did you uninstall 1.3 completely? Completely in the sense both jdk and jre.
You may get this error if you use javac of one version and the rt.jar of another version.

Is it possible to use the java.lang.ProcessBuilder to execute a Java process pointing it to jvm.dll instead of java.exe? I'm using the JavaFX self contained application packaging and it creates a runtime/jre/bin directory that contains jvm.dll, but not java.exe.I don't get the line of questioning of this thread. If you're using the JavaFX stuff the answer must lie in the JavaFX documentation. It seems to indicate that it generates an executable of its own which will likely wrap the jvm DLL, so you should be invoking the generated executable in ProcessBuilder.

          Sorry, I didn't look very closely - the exception is for
          javax.servlet.ServletConfig - should be in weblogicaux.jar.
          Is there anything wrong with it? What service pack are you
          using? Could be a problem with weblogic.policy.

Crystal Reports 2013 java-error "java.lang.ClassCastException: class com.crystaldecisions..." when promoting

Hi,
when promoting "Crystal Report 2013" report (with data connectivity BW MDX Query) from BO DEV to BO PROD with BO Promotion Mgmt (LCM), we get the following error message in LCM jobs history:
Resolution Status=Overwritten, Dependency Status=All the required dependencies are included.,
Commit Status=Commit attempted and failed.,
Promotion Status=Failure : Object promoted. Update failed.
Error: java.lang.ClassCastException: class com.crystaldecisions.sdk.occa.report.lib.ByteArray:java.net.URLClassLoader@1d634758 incompatible
with class com.crystaldecisions.sdk.occa.report.lib.PropertyBag:java.net.URLClassLoader@1d634758
The report itself is present on BO PROD, but the overwrite (BW DEV MDX Query-> BW PROD MDX Query) is not applied, so report connectivity still points to the BW Query on the development system :-( .
Moreover, the overwrite itself is detected when the job is "test promoted" ("active overwrite").
Before, we successfully were able to transport crystal reports 2013 with overwrite (the connection then pointed to BW PROD). No idea yet what suddenly changed that...
Any ideas what causes the error and what can fix it (no posts found, no SAP note, google also no hits)?
Best regards
Florian Pitschi

Update:
After more investigation, it looks as if the BO Server "CrystalReports2013ReportApplicationServer"
from time to time has an issue - not only when promoting, but also when viewing publications that contain Crystal Report documents or when executing them, the java class error or similar issue is thrown.
Did sb face similar behaviour and knows what is the root cause for "CrystalReports2013ReportApplicationServer" not working probably and throwing the java-class error? - it was running fine for several months, now, the class error showed up twice in one month.
We need to find out what is causing the issue (aleady checked tomcat and BO-logfiles...).
Best Regards
Florian

Java.lang.Process input stream waiting until process is complete to print

I have tried to simplify this problem as much as possible. Basically, I have a java.lang.Process which executes a simple C program.
test.c
#include <stdio.h>
#include <unistd.h>
int main()
printf("foo\n");
sleep(2);
printf("bar\n");
...The process has an input stream and error stream handler each on a separate thread. I have tried both buffered and unbuffered (BufferedReader, BufferedInputStream, InputStreamReader...) stream handlers. Both produce the same problem of waiting until the process has exited to receive anything from the process's streams.
The only time this does not happen is when I call fflush(stdout); after each printf(). This can't be a solution because the real application calls a massive C application which would require thousands of fflush()'s to be added. What is causing this to happen? This doesn't happen when the C program is executed from the shell. Is there a way the InputStream can be forced to extract from the stream?

hi.....
I have closed the output stream of the process as you told me to do...
The hitch is that, if my program contains only printf() statements,it works fine
as soon as scanf() statement is encountered within the C code,it is totally neglected,and the output comes as if no scanf() statement existed in the C code.
Consequently the thread doesnt wait for input which was bound for scanf() from the thread
the code...

Problem with starting a sqlplus-process via java.lang.Process

Hi,
I want to start a sqlplus-Process from a java-application via java.lang.Process. Works great with XP. On a W2K-Machine, the process is started (I can see it in the Taskmanager), but it doesn't connect to the db - the OS-process hangs, also the java-application which invoked the process.
If I start a sqlplusw.exe-Process instead of sqlplus.exe, it works as well.
Does anybody know what's going wrong ?
I'm using java 1.5.0_11 and Oracle Database 10g Enterprise Edition Release 10.2.0.3.0
Thanks in advance
Jens

java.lang.Process can be used to perform an OS Shell to launch specific tasks. But why are you interested in specifically launching sqlplus from here?

How is the java.lang.StringBuffer class different from the java.lang.String

How is the java.lang.StringBuffer class different from the java.lang.String class?....

Read the API.
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html
"Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings."
Although when possible you should use StringBuilder instead of StringBuffer.
Always read the API at the very least before asking questions in the forums. Ideally you should do some google searching and poke around for an answer too. Otherwise you will get people barking at you.

Error : java.lang.VerifyError: (class: oracle/forms/fd/JCalendarJinit$1,..

Hi,
How to solve this error:
java.lang.VerifyError: (class: oracle/forms/fd/JCalendarJinit$1, method: <init> signature: (Loracle/forms/fd/JCalendarJinit;)V) Expecting to find object/array on stack
at oracle.forms.fd.JCalendarJinit.<init>(JCalendarJinit.java:66) ............
I edited the JCalendarJinit.java file for the JCalendar control for the Oracle Forms, I created the jar file, and when using in the forms, i am getting this error when running the oracle form,
I read, it may be version problem, How can I set the Java version to 1.3 for this java file.
Thanks in advance,

Jacob,
I have received complaints from users, that have got this error on some beans while migrating to Forms 10.1.2.3, even with Sun 1.6 plug-in.
The beans worked fine with 10.1.2

Using java.lang.Float.class causing Cannot format given Object as a Number

hi,
I have table and its model is default table model.
model = new javax.swing.table.DefaultTableModel(data,col) {Class[] types = new Class [] {
                java.lang.Object.class, java.lang.Object.class, java.lang.Object.class, java.lang.Float.class, java.lang.Integer.class
            }; public Class getColumnClass(int columnIndex) {
                return types [columnIndex];
            }};I want to force the user to enter float number to fourth column and integer number to fifth column. but I am gettin an error "Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: Cannot format given Object as a Number" like this. cause of this error is "java.lang.Float.class". and when I use Integer instead of Float the is no problem. Could you please help ?

It depends on model data.

About java.lang.Process class?
