Urgent Help Required : Java Runtime.exec
Hello,
We are using the java Runtime.exec in the AIX 4.3.3 environment. Java version 1.1.8. We are consuming the output of the Runtime.exec without using the threads. i.e we are doing a readline on the output stream of the runtime and printing it to th standard output in a loop. When this is over we take the error stream and do the same.
We have two problems.
1. A ksh that is run using the java Runtime.exec is showing up multiple processes with the same as a tree structurre when we do a ps.
Why is this ?
2. Also whatever we consume from the standard output/error of runtime and print it to system.out is not being output/error. Any pointers on this ?
Thanks in advance,
Raj.
thanks !
1. we have single thread executing the command. And there are no multiple processes spawned inside the shell script also.
2. I am sorry about the phrasing. Eventhough we are catching the output stream and error stream and dumping the output correspondingly, the process ( the shell script ) hangs ! And this behaviour is sporadic. Please let us know why the process should hang !
Thanks,
rajesh.

*URGENT HELP REQUIRED* java.sql.SQLException: Invalid Oracle URL specifed
Hi all,
In the middle of the last week for my final year project and having to convert to an Oracle database due to compatibility problems with university Tomcat Server and MS Access. I'm having trouble connecting to the Oracle database and would appreciate some help please.
Running on Windows 98 in the lab here, and the Oracle 9i, release 9.2.0.2.0, J2SDK1.4.0, Classes12.zip installed OK.
Code for connection looks like this inside the constructor of my class:
Class.forName("oracle.jdbc.driver.OracleDriver");
cardSaleConnexion = DriverManager.getConnection("jdbc:oracle:[email protected]:1521:sid","user_name","pwdt");
System.out.println("Connection Successful ");
And I'm getting the following error when calling the constructor in a driver program:
java.sql.SQLException: Invalid Oracle URL specified

Please reply on a very urgent basis.
Kind regards,
PeterTry ojdbc14.jar as the JDBC driver instead of classes12.zip.

Database Driver
This section describes the known database driver issues and associated solutions.
ID Summary
4700531 On Solaris, an ORACLE JDBC driver error occurs.
This new Java Database Connectivity (JDBC) driver is for Oracle (R) working with JDK1.4. The problem is caused by a combination of the Oracle 9.1 database and ojdbc14.jar. Applying the patch will fix the problem on Solaris 32-bit machine, running an Oracle 9.0.1.3 database.
Solution
Obtain and apply the patch to your server from the Oracle Web site for Bug 2199718. Perform the following steps:
1.��Go to the Oracle web site.
2.��Click the 'patches' button.
3.��Type 2199718 in the patch number field.
4.��Click the 32-bit Solaris OS patch.Go to Metalink.oracle.com.
5.��Click patches.
6.��Under patch number, enter 2199718.
7.��Click the 32 bit Solaris OS patch.
4707531 On Solaris, accessing an Oracle 9.1 database with an Oracle 9.2 Client may cause data corruption.
If you use an Oracle (R) 9.2 client to access an Oracle 9.1 database, data corruption might occur when a number column follows a timestamp column.
The problem might be caused by using the ojdbc14.jar file with an Oracle 9.1 database. Applying the patch might assist in addressing the situation on Solaris 32-bit machines, running an Oracle 9.1 database. This JDBC driver is for Oracle working with JDK1.4.
Solution
Obtain the patch that Oracle might make available from the Oracle web site for Bug 2199718 and apply it to your server.

[Solved] Update of one of the packages requires java-runtime-openjdk
Hi.
I wanted to perform a system update today but what I encountered is that one of the packages wants specifically a java-runtime-openjdk instead of java-runtime.
I wonder what package and why. I don't want to install openjdk since I use an Oracle JDK.
How do I find out what package wants openjdk?
The list of outdated packages is a bit long.

It's probably due to it hadn't updated for a while so I found it out only now.
I've had openjdk before and it probably installed icedtea-web as a dependency.
Some time ago I forced-removed openjdk and installed Oracle JDK from AUR instead assuming that all the packages that required java-runtime won't get their dependencies twisted.
I did not know that there is a java-runtime-openjdk dependency as well.
Now it makes sense.
Thanks

Urgent Help Required for Connect Four Game
Hi all,
I am a student and I have a project due 20th of this month, I mean May 20, 2007 after 8 days. The project is about creating a Connect Four Game. I have found some code examples on the internet which helped me little bit. But there are lot of problems I am facing developing the whole game. I have drawn the Board and the two players can play. The players numbers can fill the board, but I have problem implementing the winner for the game. I need to implement the hasWon() method for Horizontal win, Vertical win and Diagonal win. I also found some code examples on the net but I was unable to make it working. I have 5 classes and one interface which I m implementing. The main problem is how to implement the hasWon() method in the PlayGame class below with Horizontal, vertical and diagonal moves.
Sorry there is so much code.
This the interface I must implement, but now I am only implementing the int move() of this interface. I will implement the rest later after solving the winner problem with your help.
Interface code..............
interface Player {
void init (Boolean color);
String name ();
int move ();
void inform (int i);
Player1 class......................

System.out.println ("What is your Number, player 1?");
player1 = scan.nextInt();
System.out.println ("Hey number"+player1+" are you prepared to CONNECT FOUR");
System.out.println();
return player1;
//Player.move();
//return player1;
}//end move method
public void init (Boolean color)
public void inform (int i)
public String name()
return "Koonda";
}//end player1 class
Player2 class...........................

//Hi,
Thanks for your help but I really don't understand the table lookup algorithm. Could you please send me some code to implement that.
I will send you the formatted code as well
Thanks for your help.

Hi all,
I am a student and I have a project due 20th of this month, I mean May 20, 2007 after 8 days. The project is about creating a Connect Four Game. I have found some code examples on the internet which helped me little bit. But there are lot of problems I am facing developing the whole game. I have drawn the Board and the two players can play. The players numbers can fill the board, but I have problem implementing the winner for the game. I need to implement the hasWon() method for Horizontal win, Vertical win and Diagonal win. I also found some code examples on the net but I was unable to make it working. I have 5 classes and one interface which I m implementing. The main problem is how to implement the hasWon() method in the PlayGame class below with Horizontal, vertical and diagonal moves.
Sorry there is so much code.
This the interface I must implement, but now I am only implementing the int move() of this interface. I will implement the rest later after solving the winner problem with your help.
Interface code..............
interface Player {

int player1;
System.out.println ("What is your Number, player 1?");
player1 = scan.nextInt();
System.out.println ("Hey number"+player1+" are you prepared to CONNECT FOUR");
System.out.println();
return player1;
//Player.move();
//return player1;
}//end move method
public void init (Boolean color)
public void inform (int i)
public String name()
return "Koonda";
}//end player1 class
Player2 class...........................
import java.util.*;

import javax.swing.*;
public class Player2 implements Player
public int move()
//int cup0,cup1,cup2,cup3,cup4,cup5,cup6;

MarinaHi,
You are very lucky that I'm currently boored. You should never tag a question as urgent. It might be urgent to you, but not to us who answer. And you should also use code formatting when you post code (see the formatting tips, or use the code-button).
I made some changes to your Graph class. The most important thing is the abstract draw method that I added to the GeomFigur class.

Urgent HELP required on forming the Matrix of data using PL/SQL
Hi All,
I'm new to this thread and require your urgent help in this regard.
I've got a requirement for building a 5000 X 5000 matrix using PL/SQL. My original data tables have 5000 rows each and I need to do a correlation analysis using this data and need to store in a physical table and not in-memory. Is this feat achievable using mere PL/SQL? I understand that Oracle DB has a limitation of 1000 columns(but not sure) and hence I'd like to know whether there is any work-around for such scenarios. If not, what are the other alternative method(s) to achieve this feat? Do I need to use any 3rd party tools to get this done? An early reply from the experts is highly appreciated.
Thanking you all Gurus in advance.

SaiWelcome to OTN!
I'll get to your quesiton in a moment, but first some welcome information. Many OTN posters consider it impolite to mark threads as "urgent". We are volunteers and have jobs of our own to do without people we don't know making demands. You are brand new and deserve some patience but please understand this. It is very likely before I finish this post someone will complain about the word "urgent" in your subject.
On to more interesting things :)
You can do the matrix, but are out of luck with a 5000 x 5000 table because Oracle only allows 1000 columns per table. There are ways to work around this.
How do do the matrix depends on what you want to do. You can do this different ways. You can create a table beforehand and use PL/SQL or simple SQL to populate it, or use the CREATE TABLE AS syntax to create and populate it in one step if you can get the underlying SQL to work the way you want, something like
create table my_table as
select a.*, b.*
from table1 a, table2 bcan populate a matrix from 2 tables with an intentional cartesian join (the WHERE clause was left out intentionally, provided your data is already in the data base.
If not you can use a PL/SQL routine to populate the data.
There are a couple of ways to solve the 1000 column limit. The easiest way might be to have 5 collections of 1000 columns each. A more complicated but more elegant soltion would be to have nested collections, allowing 2 colliections that you can loop through - a collection of collections. Nested collections can be hard to work with. A third way would be to use nested tables in the database but I personally do not like them and the insert, update, and delete statements for nested tables are hard to use.
I'm not going to give a code example because I am not sure which solution is best for you. If you have further questions post them. -
Urgent Help required! - Storing the XML as String instead as a file
Hi,
I need urgent help on this.
I have an XML file. I have used org.w3c.dom to build dom and manipulate the XML file.
I have updated the values for some of the nodes and I have deleted some of the unwanted nodes.
I am able to save the output of the DOM as another XML file using
either transform class or XMLSerializer with OutputFormatter class.
But my requirement is to save the output of the DOM into a String instead of a file.
When I save it in String, I need to have the following XML decalration and DOCTYPE declration also with it.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Test SYSTEM "Test.dtd">
Can anyone pls help me in this??
Thanks in Advance. Expecting some inpputs pls....!
Regards,
Gayathri.hi,
i think this is what u want
public static String getXmlString(Document d) {
StringWriter strResponse = null;
try {
OutputFormat format = new OutputFormat(d);
strResponse = new StringWriter();
XMLSerializer serial = new XMLSerializer( strResponse, format );
serial.asDOMSerializer();
serial.serialize(d.getDocumentElement());
catch (Exception e) {
System.out.println(e.toString());
return strResponse.toString();
}HTH

Urgent help required: Query regarding LC Variables
Hi All
Sometime earlier I was working on a performance issue raised by a customer. It was shell script that was taking almost 8-9 hrs to complete. During my research I came across a fact that there were some variables which were not set, the LC variables were impacting the sort funnel operations because of which the script was taking a long time to execute.
I asked them to export the following commands, after which the program went on smoothly and finished in a couple of mins:
export LC_COLLATE=en_US.ISO8859-1
export LC_MESSAGES=C
export LC_MONETARY=en_US.ISO8859-1
export LC_MONETARY=en_US.ISO8859-1
export HZ=100
export LC_CTYPE=en_US.ISO8859-1
export LANG=en_US.UTF-8
Later I did recover that setting the LC_COLLATE to C, is not helping and the program was again taking a lot of time. Few questions that I want to ask are:
1. Can someone please tell me, what each of these variable mean and how these values make a difference.
2. When I exported LC_COLLATE=en_US.ISO8859-1, it worked fine, but when i tried with the defalut value LC_COLLATE=C, then why the program didnt work.
As this issue is still going on, hence I would request All to provide their valuable inputs and let me know as much as possible.
Appreciate your help in this regard.
Thanks
Amit
Hi All
A new development in this regard. The customer has send us a screen shot in which they were trying to export the locale variable using the commands which I have pasted above. I can see in the screen shot that while exporting LC_COLLATE and LC_TYPE, they get a message that ""ksh: export: couldn't set locale correctly"".
Request everyone to please give their inputs as it's a bit urgent.
Thanks for all the help in advance.
Thanks
Amit

Controls the behavior of character handling functions.
LC_TIME
Specifies date and time formats, including month names, days of the week, and common full and abbreviated representations.
LC_MONETARY
Specifies monetary formats, including the currency symbol for the locale, thousands separator, sign position, the number of fractional digits, and so forth.
LC_NUMERIC
Specifies the decimal delimiter (or radix character), the thousands separator, and the grouping.
LC_COLLATE
Specifies a collation order and regular expression definition for the locale.
LC_MESSAGES
Specifies the language in which the localized messages are written, and affirmative and negative responses of the locale (yes and no strings and expressions).
You can use command
# locale -k LC_CTYPE
to see more detail about each type. -
Sending Details -- URGENT HELP REQUIRED! ! !
Hi,
I have a programming problem which I need urgent help with....
1.) I firstly have a HTML file which a user will fill out 3 fields on and submit.
2.) A servlet will get these parameters, validate some information and update a database.
Problem Part Needs to send on these details to another servlet which will be located on a seperate server.
Is there a way of doing a submit like function without an actual submit, as this will all be done away from the user.
Was initially going to use:
ctx = getServletContext();
rd = ctx.getRequestDispatcher("https://localhost:8443/servlet/FileName");But found out you can only do this with files in the same immediate location!
3.) Next servlet will accept in the same details as 2, and do some more functions and database updating. Before again sendin on some details to another servlet! (so same problem as in 2).
4.) Accepts in details from 3 and updaes database!
So does anbody have any ideas how this can be done??
Any help greatly appreciated.

sorry if its such a crime! :o(Should be obvious. You post exact question in forum A and B. Person A answers you on forum A. Person B, not knowing you were already answered because he's looking at the post on forum B, answers you on forum B, thus having wasted his time. -
Not able to open windows application With Java Runtime .exec class
Hi,
We have created a folder with mkdir() function. The folder has some
text and doc files and i want to open them using java runtime API.
I am unable to open the files using the syntax
try {
Process p=Runtime.getRuntime().exec("cmd /c \ "" + file.getPath());
p.exitValue();
catch(Exception e)
e.printStackTrace();
This code works perfectly for folders created directly in Win XP without using
mkdir.
Also the return values of of class Process is 1 which we understood as illegal thread state. But I still havent got a clue how to fix it.
Appreciate quick feedback :) Thanks ;)First off you're missing a quote (add '+ "\"" after file.getPath()). But the larger problem is that this will attempt to execute these files and they aren't directly executable (you said they're text and document files). Do you really want to execute them?
If you just want to read them then something like
BufferedReader ir = new BufferedReader(new FileReader(file))
would be more appropriate. -
Java Runtime.exec running java problem
Hi, I have a simple server application, which I would like to run in the background. The following line works for me:
Runtime.getRuntime().exec("cmd /c start java -jar ..\\server\\server.jar -Dlog4j.configuration=file:src\\test\\resources\\log4j.properties -filename src\\test\\resources\\server.properties");But it displays the cmd window and I am unable to destroy it. So I would like to use
Runtime.getRuntime().exec("java -jar ..\\server\\server.jar -Dlog4j.configuration=file:src\\test\\resources\\log4j.properties -filename src\\test\\resources\\serverIntegration.properties");But it simply doesn't connect to the server. That means, it starts some java process in the background, but my client fails to communicate (i dont know whether the server doesnt respond or the client fails to send the message, but still, with the cmd /c start it works). So why is that?
A related question. How do I end the process? It is a server that "doesn't end". So I have to kill it and I would assume, that running the java only command would be capable to be destroyed, but with the cmd I have no luck there. I have already tried full paths and the overload of exec with String[] params.Read [_When Runtime.exec() won't_|http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html].
One reason why your server doesn't run is that it might be writing stuff to stdout (a.k.a System.out). And if your process doesn't read the newly created process' stdout, then that other process will block until something is read (which will be never).
Read all of the pages of that article and follow its suggestions.
