Hi Pradeep,
I see your problem is not yet resolved. In your logs it is still showing the same error.
Caused by: java.sql.SQLException: ORA-01017: invalid username/password; logon denied
Execute this command correctly:
brconnect [-u system/<system_password>] –c –f chpass –u <user_name> –p <new_password>
For clarification check this link:
Changing Passwords for Database Users with BRCONNECT - Oracle on Windows - SAP Library
Check your database profile parameter password_life_time:
select * from dba_profiles;
You can set it unlimited.
