Configuration assistant "Oracle Web Services Inspection Language Configuration Assistant" failed

This post is on an issue which we faced during the BPEL installation (10.1.3.1.0). While installing the 10gAS J2ee Component we got the following error at the end of the installation where the Universal Installer runs the various configuration assistants:

The wsil.txt under $ORACLE_HOME/cfgtoollogs reported the following issue:
init: [echo] Initializing Variables
install-wsil:
install-wsil_nonjsso: [echo] Deploying WSIL App with JSSO disabled
[java] Failed at "Could not get DeploymentManager".
[java] This is typically the result of an invalid deployer URI format being supplied, the target server not being in a started state or incorrect authentication details being supplied.
[java] More information is available by enabling logging -- please see the Oracle Containers for J2EE Configuration and Administration Guide for details.

BUILD FAILED/apps/dvbef/product/AS10gR3_BPL/webservices/lib/wsil-install.xml:29: The following error occurred while executing
this line:/apps/dvbef/product/AS10gR3_BPL/webservices/lib/wsil-install.xml:35: Java returned: 1
===================================================================================
Fix: The culprit turned out to be the /etc/hosts file where the entry looked like this:
127.0.0.1 localhost localhost.domain ifdv-11 ifdv-11.acme.com
The entry should look like this:
127.0.0.1 localhost localhost.domain
172.168.10.4 ifdv-11 ifdv11.acme.com
Once you get the above entry, kill any running processes from the oracle home and delete the BPEL oracle home and restart the installation using OUI.
