HI I am a novice in forrest. I have a problem when i try to follow the installation instructions ..

When  I start with forrest run

It says

 Warning: JAVA_HOME environment variable is not set.
  If build fails because sun.* classes could not be found
  you will need to set the JAVA_HOME environment variable
  to the installation directory of java.

ERROR
=====

Unable to retrieve the org.apache.forrest.plugin.output.pdf plugin.
There may be more information about the reason for this in output
above. The usual cause is that Forrest has been unable to download
the plugin descriptor file that indicates where this plugin is to be
downloaded from. If you are behind a firewall then set the proxy.host
and proxy.port values in the forrest.properties file.

You may also like to check the value of the
forrest.plugins.descriptors property in the forrest.properties file
and ensure that the locations indicated by that value are accessible
(note there should be no spaces in this property).

1) I would like to know what is the settings i need to change for environment variables
2) I would also be happy to have a sample forrest.properties file with proxy editing. As many ppl i use proxy thru our organization's Intranet.

Help me to solve the issue.. Thanks  in advance.
