I did a new install of GF 3.0.1 on a laptop, and elected not to install the update tool as this was a fixed demo environment.
I found that when connecting to Glassfish admin, login was very slow, easily taking a minute or more longer than normal. After login, the main screen displayed a count of available updates at the top left, which I had not seen in the past. This looked suspicious and I wondered if the slowness was due to checking for available updates.
It turned out that this was indeed the case. This post discusses the issue and various workarounds, including disabling network access for Glassfish and removing a jar – neither of which I particularly liked. The post indicated that you could set preferences in the update tool, but as I had not installed it I was stuck.
I then tried reinstalling GF from scratch, this time selecting the update tool as well during install, but not selecting the check box for ‘checking for updates’. After doing this, I discovered that the problem was no longer present – login was quicker and the count of available updates was not displayed. It was also possible to use the update tool to configure preferences, but in my case automatic update checking was off anyway.
The solution to this issue, somewhat paradoxically, is therefore, if you want a fixed installation with no update checking, make sure you still select the update tool when installing, but do not enable checking for updates. This solves the problem, and also allows you to configure update preferences later if you wish.
