Maybe use java-config instead of eselect. Something like "java-config -s 1"

the system-vm and the user-vm can be the same. 
So in this case just set the user-vm to sun-jdk-1.6.0.26 by running

eselect java-vm set user 1

assuming you have only one vm as you say.

Unfortunately not can be user and system vm the same according to
output of eselect commands below.

sa-home sayusi # eselect java-vm list
Available Java Virtual Machines:
  [1]   sun-jdk-1.6  system-vm

sa-home sayusi # eselect java-vm set user 1
!!! Error: Sorry, you cannot set a user vm as root. Set the system vm instead
exiting
sa-home sayusi #

java-config is not appropriate.

sa-home sayusi # java-config-2 -L
The following VMs are available for generation-2:
*)      Sun JDK 1.6.0.26 [sun-jdk-1.6]

sa-home sayusi # java-config-2 -s sun-jdk-1.6
!!! ERROR: The user 'root' should always use the System VM

sa-home sayusi # java-config -s sun-jdk-1.6
!!! ERROR: The user 'root' should always use the System VM
sa-home sayusi #

you have to run the command as a normal user not the root user. 
Same goes for java-config as Paul suggested.

Apparently, though unproven, at 21:03 on Friday 10 June 2011, András Csányi 
did opine thusly:

That is incorrect.

java-config is quite appropriate. Using it to try and set a user vm for root 
is not, as the output clearly shows.
