I wrote a project in NetBeans IDE in my computer, and I ran it. That was OK. I transferred it into my Friend's computer. I ran it with NetBeans, but I got these errors:

It's not the same error. Your friend has an older Java version. Here's how to target older Java versions in NetBeans: Target JDK for Java Applications.
You are running your program incorrectly. You need to do
java friendspro.Server.RunServer -ORBIniti ...
in your main directory (probably bin or src).
On your computer, open CMD, cd to your source directory and then, as Banthar specified,
java friendpro.Server.RunServer ...

I just installed apache-ant using MacPorts:
sudo port install apache-ant
When I type ant -version, I get the following:

How can I fix this?
you need to upgrade the JRE you're running it with - the jar is compiled with 1.8
let's say in a package using Java we are using 4 files.
First one say StudentModel.java ,second one say studentView.java,the third studentController.java and fourth studentMain.java.
Then I compiled these files in these order in one line studentModel.java , studentView.java , sudentController.java and studentMain.java.
But I received the following runtime error while running this command :
java studentMain
in spite of having the respective .class files in the folder :

RunTime Error while setting the classpath
I'm trying to run a simple unit test to my project at https://github.com/cdwijayarathna/oj4j.
I added both junit-4.12.jar and ant-junit4.jar to the lib folder.
But when I ran "rake run_tests", I'm getting following error at the report location I have given.

What's the reason for that? how can I solve this?
I had the same exception running junit through ant on Debian. By including the junit4.jar in the $CLASSPATH environment variable I was able to get it running. Which means the jvm was not picking up on the junit4.jar. The /usr/share/java/junit4.jar path is specific to Debian's junit package, so you will need to replace as appropriate.
$ export CLASSPATH=/usr/share/java/junit4.jar
$ ant test
I use specific jars to run tests on a project, here is the command line which solve this issue:
$ CLASSPATH=lib/hamcrest-core-1.3.jar:lib/junit-4.12.jar ant my-junit-target
I've wrote a small shell to encapsulate this command.
Set ANT_HOME your $CLASSPATH environment variables.
When I want to start Kettle:
$ cd ../kettle/data-integration
$ spoon.sh
The following error appears:

What's wrong? Can anyone help?Many thanks.
Kettle is currently (5.0) supported using Java 7, please try with JDK or JRE 7
That class should be in the pentaho-xul-core jar located in your lib folder, there's a pretty serious problem with your classpath if it can't be found
Please edit spoon.sh to echo the command it's about to run on the last line (add "echo " at the beginning of the last line, exclude the quotes) and post what it comes out with.

By the looks of it the Groovy libs are not being found or something.
The problem is that I was using a symlink that pointed to /usr/local. The error was fixed by changing the classpath to use the direct path of /usr/local instead of a symlink.
tl;dr: Don't set your classpath in IntelliJ using a symlink.
