After surfing java.sun.com following your suggestion, i found it quite easy (theoritically) to run Java in 64 bit environment. These are the following steps :
1. Install the OS, i hope SUSE 9 already supports itanium 64 bit
2. Install the 32 bit SDK/JRE for Solaris SPARC Platform or the 64 bit SDK/JRE for Linux or others
3. Complete the VM installation with the files for 64 bit support (for Solaris SPARC Platform)
Here is the url :
SDK/JRE download page Thanks for the info !
