1.JDK must be installed in the system first..if./bin file
is there then JDK is not necessary(platform dependency).if
you are going for generic then JDK must be installed in
your environment.
2. All the ports should be opened between webserver and
application server and also between application sever and
database.
3.check the diskspace in the filesystem.you need min of 1gb
of hardware memory for 1 installation.and remeber there
will be logfiles and stackraces to occupy memory so min of
10gb is required
4.check for the file permission issues and access to root
for installing JDK.
