jar file execution

Thu, 8 May 2008 21:18:57 MDT

I have developed a swing application and executing under linux environment. jar file is present under /deo/temp/testing.jar. I have two issues to share now.

1. If I execute my jar file under /deo/temp> java -jar testing.jar, I am able to see my application start running. But if I try like /deo>java -jar /temp/testing.jar, I get the error message "Main method not found"
How do I resolve this problem?

2. How do I create an icon so that when the user clicks the jar file, it starts executing. In windows, as I have developed using netbeans, if I double click the ajr file found under dist folder, the program starts executing. As the users are not aware of using command line prompt, I am supposed to make an icon ...

jar file execution in linux.

Thu, 8 May 2008 21:14:57 MDT

I have opened a topic under http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=33&t=026491, (http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=33&t=026491,) but then realised this might be an apt place.

I have created a swing application under windows enviroment using netbeans. It works perfectly fine when I double click the jar file. Then I moved my source code under linux machine /home/userrig/temp/testing.jar. If I chane my dir to cd /home/deo/temp and start executing jar like

code:

java -jar testing.jar

, swing application starts executing. But if I try to start the swing application under /home like

code:

Default web user

Wed, 7 May 2008 11:24:53 MDT

In Windows, the default web user is IUSR_*****. If I'm setting up permissions for the internet user for a Linux machine what is the typical username in there that would correspond to that? Is there additional steps needed for Linux setups?

What command to call app for mimetype

Wed, 7 May 2008 09:12:53 MDT

What command/program can I execute in a script to call the application associated with a mimetype/file extension? Like when you are in a File browser and you "open" a file.
The syntax in a script file would be:

The coding would be: $1

For example, if were: Something.html
then would start a browser and have it open Something.html

Another example, if were: Picture.jpg
then would start an image program and have it open Picture.jpg

Thanks,

Environment variables in geany

Wed, 7 May 2008 09:12:52 MDT

Is it possible to use Enviroment variables when using the Execute button in geany?
I have a script: /home/me/bin/nt with /home/me/bin being on the PATH variable.
The nt script uses several environment variables. I've tested it from a terminal commandline and it works.
But when I use it from geany via the Execute button, the environment variables come up empty.

Skinny Java IDE for Linux (Ubuntu)

Sat, 3 May 2008 11:58:31 MDT

Can you recommend a skinny Java IDE for Java?
I installed netbeans but its way to big and structured.
All I need is an editor that knows and highlights Java syntax and that has commmandline access that I can prime to compile and execute programs.

thanks,

I like Ubuntu 8.04

Fri, 2 May 2008 05:58:28 MDT

I just installed the heron on an external drive and I like it. It is fast, clean and easy so far. Running noticeably faster than my 7.10 installation, although it isn't really fair to compare a clean install to an old one.

Running ANT on Linux

Thu, 24 Apr 2008 10:40:03 MDT

Hello everyone!

I need your help on running the ant task on Linux box. It might sound simple (and so it was for me), however, things turned out to be rather ugly. Any kind of help is appreciated. Now, here's what I'm trying to do:

Suppose I have a build.xml script, which includes a following task:
destdir="..."
includes="*.*"
extension=".xml
style="ContentCleanup.xsl"/>

Basically, what it supposed to is to grab all the XML files from the base directory, run it through the aforementioned XSL file and output the results to the destination directory. Short and simple. However, there are thousands of these files to process and to get...

Linux/J2EE questions

Thu, 24 Apr 2008 09:54:03 MDT

Hi,

First of all, let me preface my questions by saying that I have tinkered with various versions of Linux over the years, but this is the first time that I've done anything like install j2ee on Linux. But, I've installed j2ee on several Win machines so I do have experience there. Having said all this, let's get on to the questions that I have.

1. This is more of a basic Linux question, but applies because of the situation. Do you have to uninstall j2ee from Linux if you want it to exist in another folder or can you just move it lock, stock and barrel?

2. As I stated, I've often installed j2ee on a Win machine, so I'm familiar with the necessary configurations that have to be set up in order for Java to ...

Using Java in Linux

Thu, 10 Apr 2008 20:33:06 MDT

I have downloaded JDK6 and installed it, but when I try to do javac I get this.

The program 'javac' can be found in the following packages:
* gcj-4.1
* jikes-sun
* jikes-sablevm
* gcj-4.2
* kaffe
* jikes-classpath
* java-gcj-compat-dev
* ecj
* j2sdk1.4
* jikes-gij
* jikes-kaffe
* sun-java5-jdk
* sun-java6-jdk
Try: sudo apt-get install <selected package>
bash: javac: command not found

I have tried it at my desktop(where the java file is saved) and I have tried it in the bin folder where javac is actually found and it still does not work. Any Ideas? I have used Netbeans and it compiles fine so I'm pretty sure ...

Get memory usage of a pid....

Thu, 10 Apr 2008 09:15:05 MDT

I have an application, called BASE, running on a Unix machine. I have second application, called TESTER, running on a Windows machine. TESTER provides load testing for BASE.

Is there a way, from within TESTER, to use Java to get the CPU Usage and memory footprint of BASE from UNIX remotely?

Thank you for your advice and response in advance!
