Issue with multiple Demantra Schema on same local machine

  I had demantra installed in my localmachine. I created a new schema and changed the username and password in the server.xml file. I am able to connect to the new schema from Business Modeller and SQL Developer. But I get errors while starting the tomcat server and on logging into Collaborator Workbench and Workflow Manager I get the error "Invalid Username and Password". Could you please help me with your solutions
