Apache Ignite datasource in WildFly

I am trying to setup Apache Ignite Cluster with WildFly 10.1.0, so I'm able to use JPA with Ignite. I have issues configuring the JDBC driver.

What I have done so far:

standalone-full.xml

<datasource jta="false" jndi-name="java:jboss/datasources/IgniteDS" pool-name="IgniteDS" enabled="true">
   <connection-url>jdbc:ignite:thin://172.X.X.146,172.X.X.147,172.X.X.148</connection-url>
   <driver>ignite</driver>
</datasource>

Later in the same file I set-up the driver

<driver name="ignite" module="org.ignite.jdbc">
    <driver-class>org.apache.ignite.IgniteJdbcThinDriver</driver-class>
</driver>

Ignite Module

In {WILDFLY_HOME}/modules I created following structure enter image description here

module.xml

<?xml version="1.0" ?>
<module xmlns="urn:jboss:module:1.1" name="org.ignite.jdbc">
    <resources>
        <resource-root path="ignite-core-2.6.0.jar"/>
    </resources>
    <dependencies>
        <module name="javax.api"/>
        <module name="javax.transaction.api"/>
    </dependencies>
</module>

Unfortunately I get following error in WildFly log when I start the server

11:43:31,253 ERROR [org.jboss.as.controller.management-operation] 
(Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address:

        "org.wildfly.data-source.IgniteDS is missing [jboss.jdbc-driver.ignite]"
    ]
}

        "org.wildfly.data-source.IgniteDS is missing [jboss.jdbc-driver.ignite]"
    ]
}

Your help is highly appreciated

  1. Beware you have 2 kinds or drivers, the regular one (driver-class), or the XA one (xa-datasource):

      <driver name="h2" module="com.h2database.h2">
      <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
  </driver>
  <driver name="postgresql" module="org.postgresql">
      <driver-class>org.postgresql.Driver</driver-class>
  </driver>

  2. I've sometimes seen conf where the driver class name is...repeated inside the datasource declaration (but do not ask me why ;-)):

 <datasource jta="false" jndi-name="java:jboss/datasources/sqlDataSource" pool-name="sqlDataSource" enabled="true" use-ccm="false">
     <connection-url>... </connection-url>
     <driver-class>com.sybase.jdbc4.jdbc.SybDriver</driver-class>
     <driver>sybase</driver>

  1. Ultimately, give a try with jta="false" (on datasource level) in case it makes some differences (I doubt but)

May be not the root cause, but the namespace of your "module.xml" file is not correct (urn should be of version 1.3 for WF 10):

<module xmlns="urn:jboss:module:1.3" name="org.ignite.jdbc">

This may prevent the module from being loaded ?

The problem was in the folder structure I've used in {WILDFLY_HOME}/modules. My path is org/ignite/main which means the name in module.xml should be changed from name="org.ignite.jdbc" to name="org.ignite"

Same change applies in driver tag in standalone-full.xml
