ApacheDS on windows 64 bit?

[Carlo.Accorsi]

Hi,
I'm looking to allocate ~3GB of memory to the JVM apache ds runs in  but I 
can't do that on 32 bit. The tankui 64bit service wrapper is not a free 
software.
I'm looking for free alternative to run apacheDS 2.0 on windows 64 bit. I see 
how one could perhaps use procrun, the wrapper used for managing,  starting & 
stopping tomcat to achieve this.
Although I have not found working examples of this anywhere. Anyone have ideas 
about this? Thanks and have a nice weekend. Carlo Accorsi.
