WildFly 31.0.0.Final datasource config fails with MySQL driver not found (as module) when launched from IntelliJ

I think I've done this dozens of times. Install a local WildFly, add a MySQL driver as module for WildFly to connect to a local DB instance. This is for WildFly 31.0.0.Final.

Here's the standalone.xml:

    <subsystem xmlns="urn:jboss:domain:datasources:7.1">
        <datasources>
            <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true" statistics-enabled="${wildfly.datasources.statistics-enabled:${wildfly.statistics-enabled:false}}">
                <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;MODE=${wildfly.h2.compatibility.mode:REGULAR}</connection-url>
                <driver>h2</driver>
                <security user-name="sa" password="sa"/>
            </datasource>
            <datasource jndi-name="java:jboss/datasources/BBStatsDS" pool-name="BBStatsDS">
                <connection-url>jdbc:mysql://localhost:3306/bbstats</connection-url>
                <driver>mysql</driver>
                <security user-name="root" password="yippieyahey"/>
            </datasource>
            <drivers>
                <driver name="h2" module="com.h2database.h2">
                    <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
                </driver>
                <driver name="mysql" module="com.mysql">
                    <driver-class>com.mysql.cj.jdbc.Driver</driver-class>
                    <xa-datasource-class>com.mysql.cj.jdbc.MysqlXADataSource</xa-datasource-class>
                </driver>
            </drivers>
        </datasources>
    </subsystem>

I installed the MySQL connector driver to WildFly under com/mysql/main:

module.xml:

<?xml version="1.0" encoding="UTF-8"?>

    <resources>
        <resource-root path="mysql-connector-j-8.3.0.jar" />
    </resources>
    
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api "/>
    </dependencies>
</module>

I double-checked the driver in the admin console, which seems to be OK:

But when I launch the server (from IntelliJ), I get:

EDIT:

Launching via standalone.sh doesn't make any difference from what I see:

Q:

What's wrong?

Is the server too new for the driver?

Solution

  • Instead of adding mysql driver as a module try adding to your pom file.

    <dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.33</version>
</dependency>

    I also suggest defining datasource with @DataSourceDefinition annotation that way your code will be Application server agnostic and it is lot easier if you work with Docker. configuration as code.

    import jakarta.annotation.sql.DataSourceDefinition;
import jakarta.ejb.Singleton;

@Singleton
@DataSourceDefinition(
    name = "java:app/deneme2DS",
    className = "org.h2.jdbcx.JdbcDataSource",
    url = "jdbc:h2:mem:test;DB_CLOSE_DELAY=-1",
    user = "sa",
    password = "sa"
)
public class DataSourceConfig {

    // This class can be empty, as it only serves to define the DataSource
    // The DataSource will be automatically registered when this class is loaded

}

    Finally remove the driver and datasource definitions from your standalone.xml and also remove the MySQL driver JAR from the modules dir.
