soa-createUDD.py execution error

Hi, I'm trying to setup SOA HA on a linux environment

when I try to execute soa-createUDD.py ((I’m referring Enterprise deployment guide for Oracle SOA Suite > Section 5.5)

=============
Before you can start the WLS_SOA1 managed server on SOAHOST1, you must run the
soa-createUDD.py script. You run the script using WLST offline:
1. Run the setDomainEnv.sh script to set up the environment:
SOAHOST1>. ORACLE_BASE/admin/<domain_name>/aserver/<domain_name>/bin/
setDomainEnv.sh
2. Run the soa-createUDD.py script, which is located in the ORACLE_HOME/bin
directory:
SOAHOST1> MW_HOME/jrockit_160_14_R27.6.4-18/bin/java weblogic.WLST ORACLE_
HOME/bin/soa-createUDD.py --domain_home ORACLE_BASE/admin/<domain_
name>/aserver/<domain_name> --soacluster SOA_Cluster
=============

but my execution fails...below are the two way I tried
