Getting Firefox and Java to work with jnlp files

Comments

If you are having trouble opening a jnlp file (e.g., for IPMI console access) you can try some of these steps.

Tell Firefox to allow pop-up windows for this site

Tell Firefox how to handle the filetype .jnlp

Tell it to open it with /usr/bin/javaws

Tell Java to allow the site to run applications

If you get "Application Blocked by Java Security" you can fix that by editing an exceptions list. Modify file ~/.java/deployment/security/exception.sites Each line in this file should be a protocol and domain name or IP address for the exception, e.g.:

http://172.20.0.19
http://172.20.0.20
