Hello again everyone! I've got myself a problem trying to run a java application (with calls to Windows native libraries) on Wine 1.2. That aside, the problem is explained with this little example: Code: $ wine java -version java version "1.6.0_20" Java(TM) SE Runtime Environment (build 1.6.0_20-b02) Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode) $ wine java -xmx1024 -version Unrecognized option: -xmx1024 Could not create the Java virtual machine. A question : How does Wine report the free ram and virtual memory?? Any suggestions??? Thanks in advance. java version "1.6.0_20" Wine 1.2~rc6~0ubuntu1~karmicppa1 Linux Ubuntu 9.10 Karmic Koala 2GB ran ddr 4GB Swap space Intel Pentium 4 2.8GHz Ext4 Disk partition
