Installing Translator if Spark 1.1.1 or prior has no direct internet connection. Spark 1.1.2 (not yet available) includes the fix SPARK-225 and uses the proxy.
i was assuming that, i see JBother is using this too, but for scale deployment i would like to have plugins in one place (like with Wildfire) for offline install.
For now though, as I am sure you are aware (but this is for others who might look at the forum), you can install the plugin from within Spark, then browse to the spark folder \plugins, and take the .jar file (without needing the folder of the same name) that corresponds to the plugin out of there. You can then use it for scale deployment to your heart’'s content.
