Installing Netbeans on a remote virtual server

[TomFoolery408]

I have a remote virtual server running CentOS 6. When I try to install netbeans it throws the following exception:

java.lang.NoClassDefFoundError thrown from the UncaughtExceptionHandler in thread "main"

I attached the install.log file.

Additional info:

which java => alias java='java -Sms8m Xmx64m'
/usr/bin/java

$JAVA_HOME = /usr/bin/java

I'm accessing the virt via PUTTY.

Putty Config info is as follows:

X11 forwarding is enabled, X display location is "localhost:0"
Remote X11 authentication protocol is MIT-Magic-Cookie-1

I also have an XMing server running on my local windows machine.
