opmanager - no webserver connection shutting down

Hi.

I see this has been discussed a number of times here, however nothing seems to actually fix the issue in my case.

I am attempting to run opmanager-msp under Debian linux. After installation, running ./StartOpManagerServer.sh "Failed to establish connection with web server. Gracefully shutting down OpManager." occurrs.

As per the troubleshooting, I have ensured that the correct libraries are installed, and running ./StartWebSvr.sh gives me:

Exception in thread "main" java.lang.NoClassDefFoundError: com/adventnet/nms/util/InitWebSvr
Syntax error on line 50 of ./conf/httpd.conf:
ServerRoot must be a valid directory

If I check for the ServerRoot directory, it gives me:
ServerRoot "APACHE_ROOT_DIR" Which doesn't seem right as APACHE_ROOT_DIR is not assigned as a path anywhere that I can find. SHould this have been set to the correct path by the installation script?

There are a large number of these undefined paths throughout the config file, which I would much rather not have to go through and alter myself.

Any ideas?

Thanks,

Brent
