Installed Cell Manager but no Omnisv ? DP7

HI, 

Im about to make a Projekt with DP for my trainee finals.

Now i try to get skill with dp but nothing realy works.

i use VirtualBox an have 1 Centos VM an a Windows7 VM.

Both have a static IP and can  ping eachother. I Install the Cell Manager on the CentOS Machine 

./omnisetup.sh -CM

On the Windows Machine i Install the Client. Now i want to connect to the cellmanager from the Windows Client, but it dont works.

Check if the Cell Manager host is up and running. Check if it is accessible on 
the network (use ping command). If not, check the configuration of  
network services and routing (use nslookup command). 

I start xinetd on the Cellmanager Host and set the 5555 Port. But i think the manager is not Running. I read a lot in this Forum but every command like omnisv -?? gave me the respond "command not found".

update:

When i try to start the omnisv.sh i get the error 

1053 cannot start uiproxy

I stuck now for 2 Days, would be great if somone have a idea.
