As the envjs site http://www.envjs.com/ expired, and I want to access the doc and guides of envjs, I will setup a local envjs-site server.

First I need to download appengine java sdk with version 1.2.1, from maven repository http://mvnrepository.com/artifact/com.google.appengine/appengine-java-sdk/1.2.1, as it does not exist on google appengine official site.

Then I need to clone or download envjs-site project, and put it under /opt/webapps/

Then I need to modify the dev_appserver.sh, add

--jvm_flag=-Dappengine.user.timezone=UTC

to the java command at last line.

Run it on local:

sudo dev_appserver.sh --address=0.0.0.0 path-to-envjs-site Done.
