http://askubuntu.com – I got a warning message: jvm uses the client vm, make sure to run java with the server vm for best performance by adding -server to the command line In fact, when i run java -version i get: OpenJDK Runtime Environment (IcedTea7 2.3.2) (7u7-2.3.2a-0ubuntu0.12.04.1) OpenJDK Client VM (build 23.2-b09, mixed mode, sharing) How does one go about and change OpenJDK's defaults to always start under the server VM? (HowTos)

Yet I can't see any applets in Firefox. What's the problem?

I have a 64-bit server with only 1 GiB of RAM (VM at Rackspace). I need to run a few instances of the JVM, and the 64 bit VMs are consuming too much RAM. I can't seem to find anyplace that tells me how to install the 32-bit packages of openjdk.

I searched askubuntu and tried the suggestions but failed .I try this question:How to completely uninstall/reinstall Java
