Per http://www.oracle.com/webfolder/technetwork/hcl/hcts/device_detect.html#use , the Device Detection tool, ddtool_23.jnlp, is supposed to work directly from the noted URL on Linux systems with Kernel 2.6.x. It does not.
To get the tool working, I have to run the java ddtool_23.jnlp command. Once it starts, I see that it has apparently not been updated for Solaris 11.
So I suggest that
1) the documentation should be changed
2) the tool should be revised for Solaris 11, including the HCL for the new OS version.
