Java is a language that has a variety of projects that is perfect for many application and website designs. When programmers or learners work using Java, they end up with different errors as soon as they compile the program, which is obviously common. The exception ‘error: the unable to create requested service [org.hibernate.engine.jdbc.env.spi.jdbcenvironment]’ is one among those errors. You may encounter this warning when compiling a long code, which is frustrating.
No need to worry as you are here. We provide quick solutions that can make your code work perfectly with no error warning popping up. Let’s check out the code that causes the error
How the error warning shows up
When coding the following program, you get the error warning
hibernate.cfg.xml file
<?xml version='1.0' encoding='utf-8'?>

How to Fix ‘error: the unable to create requested service [org.hibernate.engine.jdbc.env.spi.jdbcenvironment]’
The error warning shows up when hibernate was unable to connect to the database. And that’s the reason you get the error warning.
Solution 1 – Remove Quotes
At the time of coding, a single quote can cause a problem. You need to see the example
Use this without quotes
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/hi5</property>Instead of
<property name="hibernate.connection.url">"jdbc:mysql://localhost:3306/hi5"</property>Solution 2 – Add a file name
Adding a file name can easily solve the issue in most cases.
You need to add the xml file name, like this
SessionFactory sessionFactory =
new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();instead of
SessionFactory sessionFactory =
new Configuration().configure().buildSessionFactory();Solution 3 – Database setting
To solve the error, you need to do a bit of setting. This can help you fix database issues. Follow the steps below
· You need to ensure your database is on the server that is declared in the configuration file. For example, ‘hibernatedb’.
· Make sure the username and password are correct that is used to connect to the database.
· Check the required jars are mapped to the project for the connection.
Solution 4 – Check for any double lines
Make sure you have not added any double lines in the code between the properties. It is important to be carefully when coding. The main connection properties should be coded careful and correctly.
Conclusion
We have highlighted the solutions to fix the‘error: the unable to create requested service [org.hibernate.engine.jdbc.env.spi.jdbcenvironment]’. I hope this will help!
