You can also see the tutorial I did at <a href="http://pedrorijo.com/blog/play-slick/" rel="nofollow">http://pedrorijo.com/blog/play-slick/</a>

while both aim to play 2.4.x you should be able to understand what's the error you are having. Still, there's also a PR to upgrade to play 2.5.x at <a href="https://github.com/pedrorijo91/play-slick3-steps/pull/2" rel="nofollow">https://github.com/pedrorijo91/play-slick3-steps/pull/2</a>

Finally this worked for me :-

This error killed my lot of time.

Here is what worked for me,

uncomment these line.

<pre><code> play.db {
 config = "db"
 default = "default" 
 } 
</code></pre>

then 

<pre><code> db {

 default.driver=com.mysql.jdbc.Driver
 default.url="jdbc:mysql://localhost:3306/playdb"
 default.username=root
 default.password="9403678957"
}
</code></pre>

don't need<code>db.default.*</code>, as you already in the db set range.

Lots of thanks to this <a href="https://groups.google.com/d/msg/play-framework/aL_uFk70je0/1qpnzHY0AgAJ" rel="noreferrer">answer</a>.

You must not specify db in the path, you are already in the db section of the config

so: 
db.default.driver=com.mysql.jdbc.Driver 
should be just: 
default.driver=com.mysql.jdbc.Driver
<code>

<pre><code>db {
 default.driver=com.mysql.jdbc.Driver
 default.url="jdbc:mysql://localhost:3306/playdb"
 default.user="root"
 default.password="9413678957"
}
</code></pre>

I am trying to connect MySQL database with Play-framework- Java 2.5.4.

I am getting this error,

<pre><code>either dataSource or dataSourceClassName is required
</code></pre>

These are the connection codes that I am using inside App.conf file,

<pre><code>db {
 db.default.driver=com.mysql.jdbc.Driver
 db.default.url="jdbc:mysql://localhost:3306/playdb"
 db.default.user="root"
 db.default.password="9413678957"
}
</code></pre>

But its giving me following errors while connecting : 

<pre><code>caused by: java.lang.IllegalArgumentException: either dataSource or dataSourceClassName is required
 at com.zaxxer.hikari.HikariConfig.validate(HikariConfig.java:785)
 at play.api.db.HikariCPConfig.toHikariConfig(HikariCPModule.scala:141)

 at play.api.db.DefaultDatabase.dataSource(Databases.scala:121)
 at play.api.db.DefaultDatabase.getConnection(Databases.scala:142)
</code></pre>

When I am connecting to mysql database with same(same as in App.conf) 

<ul>
<li>url (jdbc:mysql://localhost:3306/playdb) </li>
<li>username</li>
<li>password</li>
</ul>

Using Intellij, its working fine.

Please help me by telling me what I am doing wrong.
