Linuxhelp _ Programming in Linux _ Java In Linux

Posted by: qBANG Jul 3 2005, 08:28 AM

I am a 100% total n00b to this forum, I picked up a version of Mandrake (now "Mandriva") a long time ago and tried to learn it. I'm still in high school, where they use Windows XP Pro, so I don't boot Linux often. After taking a Java Programming class (Because I wanted to take the AP Exam), I was like "Hey, why not try my final project in Linux? I hadn't ever tried any Java in Linux. My server program worked fine, no problems. As soon as I opened the client, the JOptionPane.showInputDialog opened, asking for the IP as it should. However, there was no box to enter the IP address of the server in, is this a problem with Linux, or is it because I coded it in Windows to work with Windows? Any help is greatly appreciated. A link to a Mandrake Java compiler would be nice too.

thanks,
qBANG

Provided you are using official Java runtime environments from Sun, then java programs should run axactly the same on any platform.

I think the offical Java development kit (JDK) is available for Linux (having said that, I cant find any version of it on the sun website...)

How did you install java?

I installed the Java JDK in Windows, coded and compiled it using Windows, and then I put it on a ThumbDrive, booted Mandrake, and tried it out there. As far as I know, Mandrake comes bundled with some form of java, because I didn't install it, and when I typed "java" in the konsole, it gave me a list of arguements. I followed it like it said to, and then my showInputDialog showed up, but it was more like a showMessageDialog . I'll probably just recode it and add in a new class file to the program to create a login screen if I can't figure it out.

Thanks for checking though.

Is it a boxed version (ie bought from mandrakestore or a supplier)? The download edition doesnt come with Java etc. Try downloading a newer version of java from www.java.com (install instructions can be found at: http://www.goland.org/Installing_Java_in_Mandrake_9_1/

You should be able to uninstall the old version using the package manager in the control centre.

Thanks for your help man, I did download a version of Mandrake off the site, but the program did run for some reason, I'll try that and get back to you.
