OpenMRS showing database connection error

@mozzy I have lately been trying out this Standalone instance but it happens to be the same problem of the database connection still popping up. I have followed up the links provided above but still not getting helped out. I have tried to create an openmrs data base and also create the server3 database as suggested here Unable to find a runtime properties file by @dkayiwa and it showed some bit of success. but on logging in it failed out suggesting openmrs_user@ localhost denied. I tried creating a user in the above names but still failed. and the other thing, it being a war file, a failing to locate the openmrs property file. any further suggestions?
