I am getting following error:
Could not open JPA EntityManager for transaction; nested exception is javax.persistence.PersistenceException: org.hibernate.exception.JDBCConnectionException: Cannot open connection
Tell me how to resolve it?
You application is not able to get the database connection. Check if your application is consuming large number of database connection.
If you are facing any programming issue, such as compilation errors or not able to find the code you are looking for.
