Using Enterprise DB edb-jdbc-42.2.12.1.jar , the driver is com.edb.Driver which is in META-INF/services/java.sql.Driver.
Bundle-Description: Java JDBC 4.2 (JRE 8+) driver for EnterpriseDB database
Implementation-Title: EnterpriseDB JDBC Driver - JDBC 4.2
This configuration:

You can also specify <driver-class>com.edb.Driver</driver-class> and get the same error.
The error is misleading because it is saying the driver class com.edb.Driver is wrong, but the actual issue is a <datasource> is being defined but the driver only has <xa-datasource-class> , so it is wanting the <datasource-class> to be specified such as this:
<driver name="enterprisedb" module="com.edb"> <datasource-class>com.edb.ds.PGSimpleDataSource</datasource-class> <xa-datasource-class>com.edb.xa.PGXADataSource</xa-datasource-class> </driver>
com.edb.xa.PGXADataSource implements XADataSource but not DataSource. Some other jdbc datasources implement both such as
org.h2.jdbcx.JdbcDataSource implements XADataSource, DataSource ...
Since H2 does not complain, it is probably IronJacamar using the xa-datasource-class and casting to DataSource , though we would have to check the code.
<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</connection-url>
<driver>h2</driver>
<security>
<user-name>sa</user-name>
<password>sa</password>
</security>
</datasource>
<drivers>
<driver name="h2" module="com.h2database.h2">
<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
</driver>
</drivers>
For this error, it should say something more like com.edb.xa.PGXADataSource does not implement javax.sql.DataSource
