I am working with PlayFramework (2.3.x) application. I wanted to connect to a mysql db. Below is the configuration that I had given in application.conf:
db.default.driver="com.mysql.jdbc.Driver"
db.default.url="jdbc:mysql://localhost/mydb"
db.default.jndiName=DefaultDS
db.default.username=root
db.default.password=root
db.default.logStatements=true
jpa.default=defaultPersistenceUnitName
When I run the application I am getting the following exception
Oops, cannot start the server.

I have my db created and I am able to use with mysql console.
I have my persistence.xml placed in my conf/META-INF. Below is the persistence.xml
I have root user with all privileges.
Could anyone help me with this?
According to the docs for Play 2.3.x, the correct configuration is db.default.user and not db.default.username. That is probably the cause of the exception. So change your configuration to:
db.default.driver="com.mysql.jdbc.Driver"
db.default.url="jdbc:mysql://localhost/mydb"
db.default.jndiName=DefaultDS
db.default.user=root
db.default.password=root
db.default.logStatements=true
jpa.default=defaultPersistenceUnitName
You are not passing a login, as indicated by the line
Caused by: java.sql.SQLException: Access denied for user ''#'localhost' (using password: YES)

Any suggestions?
It looks like you do not have permission to access the PostgreSQL database.
Did you edit pg_hba.conf?
I made a video on installing OpenNMS that you might find helpful. It covers the changes you need to make to PostgreSQL so that OpenNMS can access it.
I'm deploying a JHipster app with the production profile for the first time and i want Liquibase to initialize the database with the correct tables/rows.
However when starting jhipster with the production profile it only results in an exception that say's its unable to connect to MySQL.

The error says it unable to connect for user (replaced it with 'myusername' for this post) and that no password is used for the connection. This is where the problem is, a password should be used for the connection but somehow this is not picked up from the configuration. The relevant parts of the configuration:
spring:
datasource:
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:mysql://localhost:3306/mydatabase?useUnicode=true&characterEncoding=utf8&useSSL=false
name:
username: myusername
password: SuperSecretPassword
hikari:
data-source-properties:
cachePrepStmts: true
prepStmtCacheSize: 250
prepStmtCacheSqlLimit: 2048
useServerPrepStmts: true
liquibase:
contexts: prod
password: SuperSecretPassword
I've added the password to the liquibase.password property myself but that didn't change anything. In other posts the solution was to not set a password for the database user but that is not my preferred option.
Does anyone know how to get this working?
I found out what was wrong. Is used ${spring.datasource.password} to reference the database password in the liquibase.password field but that apparently doesn't work.
These days I do exercise about JDBC.When the Java project connect the MySQL，then it's Ok.But the JavaEE project which run on MyEclipse cann't connect to MySQL,these is the error messages:

The import thing:I try to grand,restart the mysql and so on.But all of them are failed.
MySql default password is root try it, or using the "" for password.
Thanks everyone.I solve my problem.Followings are the ways:
(1:To install a newest MyEclipse software.)
2.To install a newest Tomcat7.0.64.(Warning:this is the most important way I have to solve my problem).
I'm trying to do the project explained enter link description here(the code is at the end of the page), but when I run it is risen the error:

I think that the error could be related at the CLASSPATH but I'm not sure at all. What could be the cause of this error and how could I solve it?
The root cause of this error is quite plainly explained :
SELECT command denied to user 'sqluser'#'localhost' for table 'COMMENTS'
Just be sure to create a mysql user named sqluser and grant it the appropriate rights on the 'COMMENTS' table.
Quick and dirty : GRANT ALL PRIVILEGES ON your_db_name.* TO 'sqluser'#localhost IDENTIFIED BY 'sqluserpw';
I am trying to port my code from linux to mac OSX LION. The following method works on linux just fine.
Connection getConnection() throws SQLException{
String url = "jdbc:mysql://localhost/";
return DriverManager.getConnection(url, "root", "mypassword");
}
But it's not working on my mac. I am using XAMMP so the path to my database is /Applications/XAMPP/xamppfiles/bin/mysql. The error I get reads
Exception in thread "main" java.sql.SQLException:
No suitable driver found for jdbc:mysql://localhost/
at java.sql.DriverManager.getConnection(DriverManager.java:602)
at java.sql.DriverManager.getConnection(DriverManager.java:185)
UPDATES BASED ON FEEDBACK FROM POSTS BELOW:
I downloaded the jar and add it to the project's build path. When I try to add Class.forName("com.mysql.jdbc.Driver") I get compile error so I comment it out. Then I run the program to get the following error:
Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

The JAVA JDK does not come with specific SQL drivers(i.e mySQL, postgre, MS SQL, etc). You need to download and install them separately. The download link for the java mysql connector can be found here:
http://dev.mysql.com/downloads/connector/j/
It says to put the driver in your class path, but you can also put it in your IDE's build path, it might be easier depending on what you are doing.
Make sure the mysql jdbc connector is in the CLASSPATH. You probably also need to load the driver, adding the following line before trying to get the connection:
Class.forName("com.mysql.jdbc.Driver");
You need to have you mysql jdbc connector jar on the classpath for your mac.
