Re: [Jtreeview-users] Java issue with OSX 10.4.8?

[Alok S. <al...@ca...>]

Dear Leonard,

The error typically indicates some java version incompatibility.
If you open Terminal (In Applications->Utilities) and type:

> java -version

you should get something like:

> java version "1.5.0_06"
> Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-113)
> Java HotSpot(TM) Client VM (build 1.5.0_06-68, mixed mode, sharing)

Could you cut and paste your version info?

Thanks,
Alok
