Install the JDK Development Version on CentOS

If you want access to Java tools like jar and javac, install the development version of the JDK.

# yum install java-1.7.0-openjdk-devel

Add the bin directory to your PATH so you can run the Java programs from anywhere.

# PATH=$PATH:/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.25.x86_64/bin

View the classes in a jar file.

# jar tvf dt.jar

Description: vncserver is used to start a VNC desktop. vncserver is a Perl script which simplifies the process of starting an Xvnc server. It runs Xvnc with appropriate options and starts a window manager on the VNC desktop. Here is a good implementation of VNC: TigerVNC http://tigervnc.org/ Install the server software on the Linux host. Install the server on the Linux host. I use CentOS 7. I did this as root. You can use sudo if it makes you happy. yum install tigervnc-server.x86_64 View documentat
