I have ASA 5510 running version 8.0.4 and ASDM image 6.1.5.(51). I had java ver 6 update 13 and I faced usual ASDM connection error. Downgraded to ver 6 update 7 and I can launch ASDM but the right pane is blank. Removed all other Java versions, reinstalled java 6 update 7 same issue. Removed java 6 update 7, reboot, installed Java "Version 1.6.0 (build 1.6.0-b105)" and the issue is the same. Its very frustrating. Has anyone faced a similar issue. Whats the fix, I am sure it is java, any pointers in the right direction pls.
