How to Stop JNLP file from being downloaded every time

JNLP that launches the client always downloads the client jar. I want it 开发者_运维技巧to only download the client jar if the version is newer than the local cached version.

To overcome this problem, you need to have two files on the "lib" directory under your JRE directory. "deployment.config" and "deployment.properties". this will make the jws understand that its a system deployment and not a deployment every time it is launched.

Code for "deployment.properties" file :

deployment.system.config.mandatory=true
deployment.system.cachedir=JWS 

Code for "deployment.config" file :

deployment.system.config=file:/D:/Program Files/Java/jre1.5.0_22/lib/deployment.properties
deployment.system.config.mandatory=true

Hope this helps, please update your own JRE lib directory on the deployment.config file above.

Thanks
