Hello, yesterday I tried to connect to our ASA 5520 using ASDM Launcher, which has alwasy worked before. For some reason ASDM Launcher is no longer working from both my Win XP desktop and Win XP laptop. I can open ASDM through the browser but not the launcher. Both desktop and laptop have Java 7 U 6. I'm not sure if I can back rev my Java.
an other solution is, if you have installed both versions (6 and 7) of Java, to change the properties of the launcher. Try
"C:\Program Files (x86)\Java\jre6\bin\javaw.exe" -Xms64m -Xmx512m -Dsun.swing.enableImprovedDragGesture=true -classpath lzma.jar;jploader.jar;asdm-launcher.jar;retroweaver-rt-2.0.jar com.cisco.launcher.Launcher
if you have installed Java 6 in the standard folder
Bernd, thank you. I don't have the jre6. I must have un-installed it because the jre6 folder structure is empty. But I have the jre1.6.0_18. I pointed the ASDM property to this directory and now my ASDM is happy.
