Runtime- set_right_to_left( ) Problem

Hi Experts,
I am using the runtime->set_right_to_left( ) in the Event Handler to change the RIGHT to LEFT alignment , but nothing is getting reflected. Please suggest me how to acheive right to left alignment change without logging of the BSP pages.
I know we can change the alignment before the Page display using the parameter SAP-RTL
Regards
Vikranth

Hello,
Assuming it is text for alignment -
I would suggest you to use SPAN HTML command to achieve this:
Example:
<span class=*left/right">Left hand text</span>
You can control left/right through ABAP code based on condition....
Thanks

Runtime casting problems

The following code gives me runtime casting problems:
package edu.columbia.law.markup.test;
import java.util.*;
public class A {
   protected static Hashtable hash = null;
   static {
      hash = new Hashtable ();
      hash.put ("one", "value 1");
      hash.put ("two", "value 2");
   public static void main (String args []) {
       A a = new A ();
       String keys [] = a.keys ();
       for (int i = 0; i < keys.length; i++) {
           System.out.println (keys );
public String [] keys () {
return (String []) hash.keySet ().toArray ();
The output on my console is:
java.lang.ClassCastException: [Ljava.lang.Object;
        at edu.columbia.law.markup.test.A.keys(A.java:37)
        at edu.columbia.law.markup.test.A.main(A.java:29)I can not understand why is it a problem for JVM to cast?
Any ideas?
Thanks,
Alex.

return (String []) hash.keySet ().toArray ();This form of toArray returns an Object[] reference to an Object[] object. You cannot cast a reference to an Object[] object to a String[] reference for the same reason that you cannot cast a reference to a Object object to a String reference.
You must use the alternate form of toArray instead:
return (String []) hash.keySet ().toArray (new String[0]);This will return an Object[] reference to a String[] object, and this reference can be cast to a String[] reference.

Java.lang.Runtime.exec problem in ubuntu 9.10

Hi:
I tried to run some command in the java code , for example "grass64 -text /home/data/location", this command works well in the terminal, however when I call it in the java code I got some excepetions.
My code is :
public class Grass {
     public static String grassBatJob="GRASS_BATCH_JOB";
     public void run(String cmd,String jobPath) {
          //set the environments variables
          Map<String, String> env=new HashMap<String, String>();
          env.put(grassBatJob, jobPath);
          String gisDataBase="/home/kk/grass/GrassDataBase";
          String location="spearfish60";
          String mapset="PERMANENT";
          cmd=cmd+" "+gisDataBase+"/"+location+"/"+mapset;
          CommandLine line=new CommandLine(cmd);
          //the real cmd should be >>grass64 -text /home/kk/grass/GrassDataBase/spearfish60/PERMANENT
          System.out.println("start line=="+line.toString());
          DefaultExecutor de=new DefaultExecutor();
          try {
               int index=de.execute(line,env);
               System.out.println(index);
          } catch (ExecuteException e) {
               e.printStackTrace();
          } catch (IOException e) {
               e.printStackTrace();
     public static void main(String[] args) {
          String jobPath=Grass.class.getResource("grass.sh").getFile();
          new Grass().run("grass64 -text", jobPath);
The real cmd I want to execute is "grass64 -text /home/kk/grass/GrassDataBase/spearfish60/PERMANENT" with the envrionment variable "GRASS_BATCH_JOB=jobPath",it works well in the ternimal ,however in my application I got the exception"

I wonder why?

Thanks for all of your reply, and now I can run the command, however I met some problems when I tried to get the result of the exec.
The core codes are shown below:
String cmd="g.version";
String[] exe={"bash","-c",cmd};
Process p1=Runtime.getRuntime.exec(exe,env); // the env has been set
GrassThread outThread=new GrassThread("out", p1.getInputStream());
outThread.start();
GrassThread errorThread=new GrassThread("error", p1.getErrorStream());
errorThread.start();
int exitVal = p1.waitFor();
String resu=outThread.sb.toString();
System.out.println("==========the output start========");
System.out.println(resu);
System.out.println("==========the output end========");
System.out.println("ExitValue: " + exitVal); //------------------> line one
public class GrassThread extends Thread{
     public StringBuffer sb=new StringBuffer();
     public GrassThread(String type,InputStream is) {
          this.type=type;
          this.is=is;
     public void run() {
          try {
               InputStreamReader isr = new InputStreamReader(is);
               BufferedReader br = new BufferedReader(isr);
               String line = null;
               while ((line = br.readLine()) != null) {
                    System.out.println(type + ">" + line);
                    sb.append(line).append("\r"); // ----------------------------> line two
}I define a StringBuffer in the GrassThread to save the output (see the code where I marked by "line two"), and when the process complete, I check the StringBuffer to get the output (see code where I marked by "line one"), however the output in the console of the IDE are :
----------- output in the console of the IDE start -------------
==========the output start========
==========the output end========
ExitValue: 0
out>GRASS 6.4.0RC5 (2009)
----------output in the console of the IDE end--------------------
I can not understand, in the code "line one", I first get the output using "System.out.println(resu);",then I print the exitvalue,but why the order of the output in the console is not what I expected?
Another question, the code above assume the output can be got from the Process's getInputStream, however sometimes the output maybe come from the Process's getErrorStream, so how to handle it?

Runtime.exec problem

we have a c program which does the encryption on the input files.
IF we ran this program in unix os, it will take 30 secs to finish.
But if we call this program using java by calling Runtime.getRuntime().exec(command)
it takes 20 minutest to finish.
We wonder why does it take this much time to finish.
We are having thought that when the program runs in unix os it can get all the resources it want.
but when run this through java, it is limited to JRE / JVM memory size. --->Am I right?
Could you please clarify my doubt on the memory size. If I wrong, how can we fix this problem.
Thanx

In the case of unix
u will just run the executable using a.out. For processor its just the execution of the executable, so 30 secs
In case of java
step1: It has to interpret the java program line by line after doing required loading, linking and initialization
of the required libraries and class files.
step2: It has to create a separate process using Runtime.getRuntime().exec() and wait for the result
of that process
so the total time will be step1 + step2 = some time + 30 sec = 20 minutes.

Runtime error problem - Premiere Pro CS5

Just ran into a problem when trying to export a timeline as an .avi file. The process goes much more slowly than usual and when the progress bar gets to 95% an error message window opens. The title of the error is: Microsoft Visual C++ Runtime Library. The message is: This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. Then, I have no choice but to close Premiere.
I foolishly downloaded and intalled some Windows 7 updates over the weekend and am assuming they might be the culprit(s). I rolled by the system to a restore point immediately before the download, but still have the problem. Any ideas on how to correct this? Of course this happens as I'm trying to export two finished videos to show to a client today. I'm running Windows 7, 64-bit.
Thanks, Steve Pender

This may help:

I've also noticed that bearly all instances of this error come from bad versions of third-party components like drivers, so I recommend updating your drivers.

Runtime.exec() - Problem when using cvs-command

I have a problem with the Runtime.getRuntime().exec() - Command. I try to execute a command to export files from our cvs-repository. As you hopefully know, cvs produces a lot of output.
When I start my 'cvs export ... '- command from the console-window of windows, everything works perfect. But when I try to use the Runtime.getRuntime().exec("CVS export ...") the created cvs-subprocess stops after the export of the first three files. When I close the main-window, where the cvs-process was started from, the cvs-process continues working.
I could see, that many others had the same problem, but I couldn't find a real solution there.
Is there a possibility to clear/delete the output-buffer of the cvs-subprocess, because I don't really need the information, that cvs gives me. It is enough for me when cvs stores the files :-)
My source:
public void executableTest()
Runtime run = Runtime.getRuntime();
try
Process cvsProcess = run.exec("cvs export .... ");
cvsProcess.waitFor();
BufferedReader in = new BufferedReader
          ( new InputStreamReader(cvsProcess.getInputStream()) );
     String line;
     while ((line = in.readLine()) != null)
          System.out.println(line);
     catch (Exception e)
     System.out.println(e.getMessage());
Thanks for your help.

if the buffer is overflowing, then you don't want to do the waitfor until after you've hit the end of the inputstream, me thinks.

DSC runtime engine problems

Hi,
I recently started a project which involves DSC runtime engine. This being my first contact with runtime engines, i obviously ran into some problems. Hope someone can shed some light. Here goes: I developed a project on my work laptop on which I have LV / DSC 8.6 installed. The project is then built into an EXE application and then run on a desktop computer with DSC runtime engine.The desktop computer receives data from a PLC through an OPC server (which is not NI OPC server). At first, I imported a csv file containing the list of variables in my project with the correct path of the OPC server from the desktop. When I ran the EXE application on the desktop, I got an error (PSP Led was red) saying that the variables could not be read / written. This was because the variables were not declared in the Distributed System Manager. And so my first question is this: is there a way to import my list of variables from a csv file or something similar, and if so, how can i achieve this? Because so far, all I was able to do was to manually enter only one variable at a time in the Distributed System Manager, and after about 50 of them I decided I would really hate to enter almost 800...
My next question regards the Citadel Database. As I told you before, I entered a few variables in the system manager and played with them for a brief amount of time. I set them T / F, I got the correct readings from OPC server, my PLC leds light up, the works. Now I wanted to see my actions in the Citadel DB, but when i ran MAX, there was no Citadel DB, only Default DB, and I could not find any of those variables which I entered and chaged states. Is there a problem with the Citadel DB not showing up? Am I not declaring correctly the variables in the System Manager? (i followed the help directions to the letter). Anyone has an idea as to why I cannot see the varaibles in my DB?
And now for a final problem.. In the LV front panel, i have some boolean buttons which are set to switch when pressed Mechanical Action. When I have the PLC connected sometimes when I press a button, it remains stuck on the TRUE state, thus screwing up my logic scheme (e.g. for a feed mill conveyor motor I have two buttons - start, stop. If i sometimes press the start button and it gets stuck, i can no longer SHUT DOWN that conveyor, which is really a big problem. I found a so-called 'fix' - right click on the stuck button and select Reinitialize to default value, but I was looking for an answer to understand this problem, not a silly little fix).
Hope I have been clear enough and you have not got tired of reading so much,
Cheers,
Sabin

Hi Andrew and thanks for the reply!
I don't think I deployed the library file, because I didn't know exactly how to do it. In the Source Files Property Page on Build Specifications I only selected VIs. I never selected lvlib files, so this may be the case. On the Source File Settings I saw that .lvlib files had the property Include if referenced and I thought that was the property which deployed the library. I will change the build specifications at once and keep you updated, but it could take 1 or 2 more days, because the computer with DSC runtime is in another city, and I have to get there first maybe tomorrow.
I have several buttons set on Mechanical Action Switch Until Released. They are all Shared Variables which are connected through OPC server to memory locations in the PLC CPU. In my LV Block Diagram, they are NOT connected to anything. They are just located in a While Loop, to get their state. The preffered action is that when I press a button on my Front Panel, I get to change a memory location in my PLC and then something happens in Ladder Logic. So, the boolean values are just there, in my Block Diagram, alone and not connected to anything. Do you have an idea as to why I get that kind of behaviour (I mean the buttons get stuck on True state)?
And finally, someone told me that the Citadel 5 might be missing because of incorrect option checking at install. However, I remeber that on the desktop, I installed the DSC runtime engine FULL INSTALL, I mean I checked each and every tick box, everything, examples and the like. One thing I was told was to insert the install CD once again and perform a re-install. I will of course try this, but let's not consider this for a second. Do you have another idea as to why the Citadel DB wouldn't show up?
And no, in the EXE Build Specifications, I did not check the option Enable Enhanced DSC Run-Time support. What does it do? Could you please elaborate?
Looking forward to your answer,
Sabin

J2SE Runtime update problem (win32/Firefox)

I am installing the J2SE Runtime Environment 5.0 Update 6 for Firefox 1.0.6 and am getting the error:
Error 1335. The cabinet file `jc150000[1].cab` required for this installation is corrupt and cannot be used. This could indicate a network error, an error reading from the CD-ROM, or a problem with this package.
The update is being downloaded live and yes I quit Firefox before proceeding.

Runtime.exec problems

Hi
I would like to open a chm file from my "help" menu.
I got two problem related to that:
1.The first time the menu is clicked i start the process and the help is opened on top of my application frame.
but - the second time It is opened - the only wat to recognize i sthe process is still active is to call exitValue (if it get an exception - process is still active) but - how can i make the frame on top of my application frame( the current active frame)
2.when the application is closed the help application does not "die" with the rest of the application.
I will be happy to get some ideas of how can i control it.
this is my code:
Runtime runtime= Runtime.getRuntime();
        try {
            if(process==null){
                 process=runtime.exec(new String[] {"cmd.exe","/c" , helpLink});
            else{
                try {
                    process.exitValue();
                    process = runtime.exec(new String[]{"cmd.exe", "/c", helpLink});
                    if (log.isDebugEnabled())
                        log.debug("process finish working");
                } catch (IllegalThreadStateException e1) {
                    if (log.isDebugEnabled())
                        log.debug("process still working");
        } catch (IOException e1) {
            if (log.isErrorEnabled()){
                log.error("could not open help file"+ helpLink);
                log.error("exception:",e1);
            WorkingAreaManager.getWorkingAreaManagerInstance().displayErrorMessage(COULD_OPEN_HELP);
        }thanks,Liat

1.The first time the menu is clicked i start the
process and the help is opened on top of my
application frame.
but - the second time It is opened - the only wat to
recognize i sthe process is still active is to call
exitValue (if it get an exception - process is still
active) but - how can i make the frame on top of my
application frame( the current active frame)Sorry I don't know the answer to that. What happens if you invoke it a second time... does it bring up a completely new frame?
2.when the application is closed the help application
does not "die" with the rest of the application.
I will be happy to get some ideas of how can i
control it.process.destroy()?

Runtime exec() Problem, change working dir

Hi!
I have following problem:
I want to call an executable from my home-directory under Linux this way:
Runtime rt = Runtime.getRuntime();
Process pr = rt.exec("/home/tom/prog/exec-command");
Unfortunately I'm getting either exception "file not found" (but it's there) or no complain but no program run...
perhaps something's wrong with the path-name?
If I call the program in the directory with a shell it works fine.
Would be very happy if anybody can give a hint!
Thanks a lot,
Manuel

You are interested in the programs output? Does it write to stdout or stderr or both? In any case, my advice is to go multithreading and use one thread to wait for the program to exit, one to read stdout and one to read stderr. If you just use one thread for reading, the program might block. I normally use something like this:
final int BUFFER = 2048;
final Process p = Runtime.getRuntime().exec(args);
//read standard out output of the external executable
//in seperate thread to avoid I/O deadlocks
new Thread()
    public void run()
     try
       BufferedInputStream in = new BufferedInputStream (p.getInputStream());
       int i;
       byte[] buf = new byte[BUFFER];
       while ( (i = in.read(buf, 0, BUFFER)) != -1 )
          System.out.write(buf, 0, i);
       in.close();
     catch (IOException e)
       e.printStackTrace();
}.start();
//read standard error output of the external executable
//in seperate thread for symmetry
new Thread()
    public void run()
     try
       BufferedInputStream in = new BufferedInputStream (p.getErrorStream());
       int i;
       byte[] buf = new byte[BUFFER];
       while ( (i = in.read(buf, 0, BUFFER)) != -1 )
          System.err.write(buf, 0, i);
       in.close();
     catch (IOException e)
       e.printStackTrace();
}.start();
//Wait for the external process to finish
int exitCode = p.waitFor();
if ( exitCode != 0 )
    throw new IOException("Executable stopped with error code "+exitCode); Cheers, HJK

Runtime Environment Problems

Hey all -
new to Java and I have been able to run most of my applications / applets however, my first attempt at accessing a database I continually get the following error:
Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion'
has value '1.3', but '1.4' is required.
Error: could not find java.dll
Error: could not find Java 2 Runtime Environment.
Don't know why all of a sudden I am receiving this error. Any help would be appreciated.
Thanks

You have (at least parts) 2 different JRE's in the machine. I'm guessing that you installed an IDE with an older version of java on top of a newer version? If, not you might explain what was done, to facilitate additional diagnosis.
However, the problem is that a Registry key - the one mentioned - has the wrong value. You can correct the key if you know what it should be and know how, or you can uninstall in reverse order of installs, and then reinstall the version you want.
Search these forums for the error, there are many threads with much detail.

4D Runtime 2004 - problems with Leopard

I have major problems with 4D Runtime 2004 on Leopard.
Does anybody know if/when 4D (2004) will be compatible with Leopard ?

Its easy to blame OS X without giving a reason why - in cases like this the easiest thing to do is to lay the blame at the feet of OS X without any substantiation.
Is your OS fully updated or are are there further updates you can download? There may be, for example a keyboard firmware update you need to install.
There may also be some updates for Office you can install.
Also bear in mind that Office 2004 is not Intel native and uses [Rosetta Emulation|http://www.apple.com/rosetta>. Upgrading to Office 2008 may also be worth considering as it is Intel ready.

Runtime.exec Problem with setting environment

Hello
I will run a command with a new process environment. As example I take "ls". If I use the "exec(String)" method it works fine (like it should; my PATH is ...:/usr/bin:...).
Next when I use "exec(String cmd, String[] env)" with cmd = ls and env = {PATH=} then the programm also prints out the listing of the current directory. In my opinion this shoudn't work.
I have the problem using jdk1.2.2 (Solaris VM (build olaris_JDK_1.2.2_10, native threads, sunwjit)) on Solaris 8.
As I understand the exec the method should work like this:
1. fork a new Process
2 set environment for the new process
3 exec the new Programm in this process
Is this statement right?
On Solaris 2.6 the program works fine and I get an IOException.
Some hints way the env for the process isn't set?
Thanks

Runtime.exec--problems writing to external file

Hi. I went to http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html, and am still quite confused regarding the use of Runtime.exec, for my purposes. I want to decompile a CLASS file using javap, and then write that to a TXT file, for easier reading/input to JAVA. Now, I use the following code (a modification of what I got from http://www.mountainstorm.com/publications/javazine.html, as the "traps" article's sample code is WAY too confusing--they say the compiler had the output sent to text.txt, without even showing how in the source code they did that), but it hangs up. Modifications to the string array cause different results, such as showing the javap help menu, or saying that the class wasn't found, but I think the way I did the array here is right:
import java.util.*;
import java.io.*;
public class Test {
        try {
         String ls_str;
            String[] cmd = {"C:\\j2sdk1.4.2_04\\bin\\javap", "-c", "-classpath", "H:\\Java\\metricTest", "metricTest > blah.txt", ""};
            Process ls_proc = Runtime.getRuntime().exec(cmd);
         // get its output (your input) stream
         DataInputStream ls_in = new DataInputStream(
                                          ls_proc.getInputStream());

          System.exit(0);

         System.err.println(e1);

}

Also, jesie, I realize that's what I need...the only
problem is, the name "test.txt" is nowhere to be found
in the source code! lolLooks like I have to explain this, then.
When you look at a Java program you'll notice that it always has a "main" method whose signature looks like this:public static void main(String[] args)When you execute that program from the command line, it takes whatever strings you put after the class name and passes them to the main program as that array of strings. For example if you run it likejava UselessProgram foo bar hippothen the "java" command takes the three strings "foo", "bar", and "hippo" and puts them into that args[] array before calling the "main" method.
That means that inside the "main" method in this case, "args[0]" contains "foo", "args[1]" contains "bar", and "args[2]" contains "hippo".
Now go back to the example and see how it lines up with that.
