Not exactly sure what you expect as you don't really provide anything useful ...

Start looking at log files, everything is logged so into the log file you will probably find something a bit more explicit.

PS: this doesn't mean to post here 2000 rows of logs, try to identify the interesting bit and if it isn't explicit enough post back that bit.

I must be missing the point:

Why don't you stay with the script then?

As you don't say what OBIEE version you use I guess it's the one with the provided ant script, so if you look into the script which work you find all the details on how to successfully start weblogic (can be because of missing env variables or permissions, but if weblogic doesn't start the logs can't be fine, it will say weblogic is going down at some point and there around you will have the reason).
