Help needed: java / fedora printing

A java print test program which used to work on fc4 and xp, now simply does not work on fedora core 5 (fc5). The test programs are here:
http://www.apl.jhu.edu/~hall/java/Swing-Tutorial/Swing-Tutorial-Printing.html
I am using a samsung ml-1750 with the hpijs driver although I do not think this matters.
The app attempts to print a jpanel image first bringing up the print dialog box, and then printing.
When the 'print' button is pressed nothing happens. If 'print to file' is chosen, an empty file is written out.
"regular" printing .e.g of a web page, kedit document etc works fine
Any and all help is appreciated. Thanks
Lou

you can try the following this fine works at my end on CentOS 4
String strCommand = "lpr#"+masterpath+"/"+filename;
                              System.out.println("Cmd="+ strCommand);
                              String[] command=strCommand.split("#");
                              p = rt.getRuntime().exec(command);

Urgent help needed(java frames)

Hi,
I need urgent help for correcting a piece of code.
I have written a piece of code for building a gui with some buttons, drawing some geometric shapes.The code consists of two files called Graph and Frame.
The problem I suppose in the last part of the Graph file, which Rectangle and Circle are called together, the only shape that the program draws is rectangle.Here is the code:

Hi,
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.
import java.awt.*;
import javax.swing.*;
import java.util.*;
public class Graph extends JPanel {
    LinkedList figures;
    public Graph() {
        setBackground(Color.white);

            super(c);
            this.p1 = new Point(p1);
            this.p2 = new Point(p2);
        public String toString() {
            return "Line from " + p1 + " to " + p2;

            g.setColor(color);
            g.fillRect(p1.x, p1.y, 20, 20);

Help needed setting up print server

i got 2 printer:
1 usb inkjet epson 1290
1 hp5100 network
i have 1 server:
serving epson for our col proof using powerripx as driver and shared via os x print server
i have 2 network interface card on the server.
my problem is: the position of the server in the office has only one network interface port, i want to have my HP connected to the 2nd network interface of the server and the server connected to the only available network point there and thus have the server serving both printer.
have set up the en1 interface, enable NAT, dhcp, firewall, but the server itself does not recognised the hp which is connected to the 2nd ethernet interface. when i move it on top of the ethernet list in system preferences it does recegnised it but the the whole print server is not accessible on the network.
can someone with more experience help me set this up.
thx

I didn't say it's impossible. I just offered an easy solution to your problem that will save you and you users some hassle in the long run (eg. when you come to troubleshoot you wn;t have to look at 2 networks and a firewall). I guess I just like easy solutions. And ,dude, 20 bucks...
If you want to go the hard(er) way you need to:
1. set up a second network address range on the second card
2. give the printer a fixed IP address within that range
3. ensure firewall is not blocking packets from/to the printer
4. config the printer on your print server & clients

Help needed with existing printer for MacBook

Apologies if this question is in the wrong section of the forum - please feel free to move it!
I am new to the "Apple Experience" and have had this superb MacBook for a couple of week now. I need to connect my existing laser printer, a Samsung ML-1750 to the MacBook and so far, I have had no joy. The Samsung website is not a lot of help with regard to downloading a Mac driver and while the MacBook seems to have found the ML-1750, when printing, the printer just outputs a load of garbage! From where do I obtain the correct driver!
Please help!
Thanks, Dan

Hi Dan,
welcome to macbook forum,
Try gimp-print as suggested by Kappy and or you can choose either the nearest model to your samsungs or generic post scripts printer.

You're still blank. Not even close to correct. You don't seem to know Java well enough to tackle this. You will NOT be able to accomplish this by asking questions here. Go back and learn more basics.

In the main up top, i can get the connection to open/ Oarcle1.Open works and it gives me no compile errors
but when i try to do the same thing in the createTables it gives me the evil red line under open and says
"The method Open() is undefined for the type Object"Where are you calling the createTables method ? How will the compiler know that it has to start off with the createTables ?
Open() is not a static method either ...?!?!?!?
what are you trying to do ?

[HELP NEED] Delivery Note Printing

Printouts are printing in the correct device, but Delivery notes are still printing in the old device.
Can anyone suggest where we could configure the output device for the Delivery notes printing?
Checked already in SPAD/UNIX and the printer (output device) is already pointing to the correct and new IP address.
Appreciate any help on this! Thank you!

Hi Mariel,
Please validate following points
1) Check the nace configuration for the output type used. you normally specially the default printer name for the output type in nace.
2) Check which printer is selected for your output type in VL02N.
3) In the driver program check which printer is passed to NAST-DEST
4) Also check which is you default printer on your computer. if you have set up locl as the printer type in nace then it will always pickup the default printer on your computer.
Hope this helps.
Thanks
Sumit

Bing-Bar help needed for Smart Print activation

I attempted to install Bing bar, but get the message that my computer will only install in Explorer,which is what I am using. I have a Windows xp, and an HP Photosmart printer

You don't need the Bing bar for smart print any longer. I'm using IE9 and have uninstalled the Bing bar.

JDBC help needed ; java.lang.NoClassDefFoundError:test1

hi, everyone, i had a problem when i run my own app to connect javadb in embedded mode
i ve added the ~/javadb/lib/derby.jar to CLASSPATH
and ~/javadb/lib/derby.jar:~/javadb/lib/derbytools.jar to DERBY_HOME
but there is a problem said my own application class cannot be found.
here is my code:
import java.sql.*;
class test1
public static void main (String args [])
       throws SQLException
     try {
        Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
    } catch (Exception e) {
        System.out.println("ERROR: failed to load javadb JDBC driver.");
        e.printStackTrace();
        return;
      Connection conn = DriverManager.getConnection("jdbc:derby:testdb");
try{
     Statement stmt1 = conn.createStatement();
        ResultSet rset1 = stmt1.executeQuery( "SELECT * FROM PART" );
     long counter1 = 0;
        double price1;
     while ( rset1.next() )
         price1 = rset1.getDouble(8);
         if (price1 == 1306.4)
          counter1++;
     System.out.println( counter1 );
     stmt1.executeQuery("SHUTDOWN");
     conn.close();
   catch (SQLException e )
     String errmsg = e.getMessage();
     System.out.println( errmsg );
}and i ve followed one Derby JDBC tutorial on the internet,

      System.out.println("\nDriver for jdbc:derby://somehost/somedb");
      System.out.println("   "+driverClass.getClass().getName());
      listDrivers();
    } catch (Exception e) {
      System.err.println("Exception: "+e.getMessage());
private static void listDrivers() {
    Enumeration driverList = DriverManager.getDrivers();

The output below confirms that the DriverManager class is able to load any JDBC driver classes as long as their JAR files are included in the classpath.

the ij works well
and the other java app(without jdbc) works well.
anybody can help me to solve this problem?

but on my machine , it keep telling me the massage
Exception in thread "main" java.lang.NoClassDefFoundError: SimpleApp
Exception in thread "main" java.lang.NoClassDefFoundError: test1
Exception in thread "main" java.lang.NoClassDefFoundError: AutoLoadJdbcDriverI assume you get these messages when you try and run the three programs mentioned (SimpleApp, test1 and AutoLoadJdbcDriver).
What commands do you use to do this? What does the command line report the CLASSPATH to be (using the echo command)?
The simplest cause would be that you have the derby jar mentioned as part of CLASSPATH, but not the current directory.

Help needed for wireless printing.

Hi
I have tried to set up my printer via the USB connection on the TC and the printer shows up in the Airport Utility, but won't print. When I run network diagnostics, it shows that everything works OK and then the server goes from green to red.
The odd thing is that the printer then prints ' Internal error- incomplete session by time out'.
When I go through the diagnostics I get the following. message. NetworkDiagnostics was able to connect to the internet but not to the server "Samsung SCX-4500 Series.riousbprint.tcp.local
Can anyone suggest a way to get the printer working.
I am new to Mac's and networking so an 'idiots guide' type fix would be much appreciated.
Thanks

When I go in to do a design with a customer, I make sure I understand the devices that need to use the wireless. Some things you already know about (the usual wireless devices). Devices that might impact business, you need the customer to provide info on that device or a contact for that device. This way you can make sure their requirements are meet. It doesn't really matter what AP's you use as long as you know what you need to configure to make things work.
I would go with a WLC 5508 and the 3500i (internal antenna). This WLC has various options for license and depending on how many AP's you need, you can satifiy that with a base license or adding license if you add more later. YOu can also look at the 1142 AP's, but the 3500 will provide you with the capability of doing CleanAir.
WLC 5508 Licesne (table 3): http://www.cisco.com/en/US/prod/collateral/wireless/ps6302/ps8322/ps10315/data_sheet_c78-521631.html

Help Needed - Java Threads

Hi there,
It's related to Threads in Java, I have the following code and it doesnt compile using NetBeans. While it compiles and runs fine in command prompt i.e. using javac testthreads.java.
class test implements Runnable{
public void run(){
System.out.println("this is from test class");
class testthreads{
public static void main(String args[]){
test t=new test();
Thread tt=new Thread(t);
tt.start();
I get the following error when trying to compile.
init:
deps-jar:
Compiling 1 source file to C:\myjavacode\ExtendThreadClassTest0\build\classes
C:\myjavacode\ExtendThreadClassTest0\src\MainClass.java:13: cannot find symbol
symbol : constructor Thread(test)
location: class java.lang.Thread
Thread tt=new Thread(t);
1 error
BUILD FAILED (total time: 0 seconds)
If I use extends Thread instead of implements Runnable the above source code compiles fine in NetBeans as well.
Any idea what's wrong..... Pls suggest!!
Thanks!

but this seems to be the issue with netbeans ide.... any idea if I need to change any setting etc. in IDE?

Help needed in report printing output

I am trying to put that line on my report out put in my procedure which customers are getting .

I have already write one proceduce with the name of
CREATE OR REPLACE procedure fax_conf_gen_files_WF_order (cur_date date default trunc(sysdate)) is
I want to put that address at the end of my procedure, & how i can test that?
Arif

It's the statement you're using to print to the console:
println() means print, then go to next line.
print() doesn't go to the next line.
So:
System.out.println("1");
System.out.println("2");
Gives
1
2
But System.out.print("1");
System.out.print("2");
Gives
12
