Starting BIEE on Windows

Question

Hi,
I've installed BIEE on a windows machine and everything worked fine until a reboot of the server.
When I try starting BIEE, I get the following errors in a DOS window:
C:\Oracle\OraHomeBI\oc4j_bi\bin>oc4j.cmd -start

Anyone knows what this means? I'm really not into BI, so any help will do :)
Thanks!

Its purely a warning tell you that there are a set of java classes in the jar files http_client.jar,ldapjclnt10.jar and toplink.jar in two different places on your path which have different versions of the classes (and file sizes).
I have had it before on windows, but it didn't cause any issues with the actual running of OBIEE.
