Java.Sql.Sqlexception: No Suitable Driver Found for Jdbc:Mysql://Localhost:3306/Dbname

How to fix: No suitable driver found for jdbc:mysql://localhost/dbname error when using pools?

Try putting the driver jar in the server lib folder. ($CATALINA_HOME/lib)

I believe that the connection pool needs to be set up even before the application is instantiated. (At least that's how it works in Jboss)

No suitable driver found for 'jdbc:mysql://localhost:3306/mysql

In this particular case (assuming that the Class#forName() didn't throw an exception; your code is namely continuing with running instead of throwing the exception), this SQLException means that Driver#acceptsURL() has returned false for any of the loaded drivers.

And indeed, your JDBC URL is wrong:

String url = "'jdbc:mysql://localhost:3306/mysql";

Remove the singlequote:

String url = "jdbc:mysql://localhost:3306/mysql";

No suitable driver found for jdbc:mysql/localhost:3306/world

Syntax for MySQL JDBC URL is:

The general format for a JDBC URL for connecting to a MySQL server is as follows, with items in square brackets ([ ]) being optional:

jdbc:mysql://[host1][:port1][,[host2][:port2]]...[/[database]][?propertyName1=propertyValue1[&propertyName2=propertyValue2]...]

Here is a simple example for a connection URL:

jdbc:mysql://localhost:3306/sakila?profileSQL=true

Your URL jdbc:mysql/localhost:3306/world is missing a :/ after mysql.

Port number defaults to 3306, so your URL should be:

jdbc:mysql://localhost/world

No suitable driver found for jdbc:mysql://localhost:3306/rom (Payara 5, Windows 10)

Looks like I'm able to answer my own question. I asked the exact same question on the Payara Forum and was recommended to define a data source instead of using the driver directly (@Chris pointed in this direction as well). A data source is likely the best way to go anyway but I wanted to avoid the complexity and use the simplest setup .. which clearly didn't work.

For reference, you can find the working setup below:

1. In Payara 5, goto JDBC > JDBC Connection Pools > New: enter a pool name, select javax.sql.DataSource as resource type, and MySql as vendor. On step 2, com.mysql.jdbc.jdbc2.optional.MysqlDataSource should be preselected for Datasource Classname. Fill out the Username and Password (e.g., root, changeit) properties under the Additional Properties header. Select finish. On the page for the newly created connection pool, select PING to make sure it was setup correctly.

2. In your persistence.xml file, make sure the persistence-unit element starts as follows:

<persistence-unit name="ROM" transaction-type="JTA">
     <jta-data-source>java:global/<connection pool name></jta-data-source>

3. Create a web.xml file (this may also be done using Java Annotations):

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
    version="3.1">
    <data-source>
        <name>java:global/<connection pool name></name>
        <class-name>com.mysql.jdbc.jdbc2.optional.MysqlDataSource</class-name>
        <server-name>[host name, e.g., localhost]</server-name>
        <port-number>3306</port-number>
        <database-name>[db name]</database-name>
        <user>[username, e.g., root]</user>
        <password>[password]</password>
    </data-source>
</web-app>

This configuration worked for me at least. Hoping this will help someone else down the road. Note that there are various useful settings for a connection pool - see e.g., here for more options.
