Missing Frame Title

[mitesh_agg]

I am a starter in java programming.
I learned to create the GUI frame usin java awt package.
the code is as follws:

import java.awt.*;
public class Ex1 {
private Frame f;
public Ex1() {
f= new Frame("hello");
}
public void launchFrame() {
f.setSize(400,300);
f.setVisible(true);
}
public static void main(String a[]) {
Ex1 gw=new Ex1();
gw.launchFrame();
}
}

The code works fine in Windows XP but in Ubuntu when class file runs the title "hello" of frame is missing.
I am using JSDK 1.5 update 9 in both operatin syatem and all paths are well defined as all of my codes tried bfore run properly on both systems.

Please help me out.

Running your posted code I get the title "hello". Are you sure you are using Sun's java and not gnu's? See this post (http://ubuntuforums.org/showthread.php?t=201378) for setting up the repository version of Sun's java and making it the default on your system (just ignore the Eclipse stuff unless you want to install eclipse too)

As per ur reply i checked the compiler version "javac -version" and jre version "java -version".
Both of them are jdk1.5.0_9.
I do want to mention that, being ignorant about previously installed packages -GJC and jdk1.4, jre1.4 (as checked in Synaptic), i downloaded and installed suceesfully (without errors) SDK 1.5 update 9 with netbeans.
After installing the downloaded package I set the $PATH variable as
PATH=/opt/jdk1.5.0_9/bin:$PATH in .bash_profile successfully.
Still I am getting the mentioned problem.
Can u guide me if there is someting wrong installations or conflicts that i should modify.:confused:
