■ Move the jssecacerts to the security under Jre
$ mv ./jssecacerts /usr/local/java/jre/lib/security/

Gradle - Quick start web - new!

@ This is new version
@ If you want to develop your project in localhost,
     I recommend JettyRun in Gradle.

■ It can make your project deploy automatically.
■  File>New>Project
■  Gradle>Gradle Project


   ■ Project name: gradleJetty
   ■ Sample project: Java Quickstart


■  Open the build.gradle and Add the follew plugins
  (Delete sourceCompatibility = 1.5)
   ->apply plugin: 'war'
     apply plugin: 'jetty'
     sourceCompatibility = '1.7'
     targetCompatibility = '1.7'

■  Make the directory webapp


■  Make the index file index.html


■  Move to the project home
$ gradle jettyRun


■  Can access the follow URL
http://localhost:8080/gradleJetty

■  If you want to change http port, add this into the build.gradle

jettyRun {   httpPort = 9000
  reload = 'automatic'
  scanIntervalSeconds = 2
  // Change http://localhost:9000/gradleJetty for http://localhost:9000 
  contextPath = ''
}

■  You need to change the Classpath compiled like this.

@ Enjoy to develop your project
