    Adding a module in WildFly 8.2.0

    olivier92 Newbie

      Hi all,

       

      I am new in JBoss and I try to add a jdbc driver for derby as a module in Widlfly 8.2.0.

      What I did:

      • I added the org/apache/derby/main folder in the JBOSS_HOME/modules/system/layers/base directory
      • In this new folder, I added derbyclient.jar (from jdk 1.8.0_40, it contains the driver) and a new module.xml file.

        The module.xml file is as follows:


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

      <module xmlns="urn:jboss:module:1.0" name="org.apache.derby">

           <resources>

                <resource-root path="derbyclient.jar"/>

           </resources>

           <dependencies>

                <module name="javax.api"/>

           </dependencies>

      </module>


      Then, I updated the standalone.xml file as follows:

      • addition of this tag (in <extensions>): <extension module="org.apache.derby"/>

      Declaration of my datasource and of the driver:


      <datasource jndi-name="java:/DerbyDS" pool-name="DerbyDS" enabled="true" use-ccm="false">

           <connection-url>jdbc:derby:MyDB;create=true/connection-url>

           <driver>org.apache.derby</driver>

           <security>

                <user-name>demo</user-name>

                 <password>demo</password>

            </security> <validation>

            <validate-on-match>false</validate-on-match>

                 <background-validation>false</background-validation>

            </validation>

           <statement>

                 <share-prepared-statements>false</share-prepared-statements>

            </statement>

      </datasource>

      <drivers>

            <driver name="org.apache.derby" module="org.apache.derby">

                 <xa-datasource-class>org.apache.derby.jdbc.ClientXADataSource</xa-datasource-class>

           </driver>

           <driver name="h2" module="com.h2database.h2">

                <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>

            </driver>

      </drivers>


      I am getting the following error when I start WildFly:


      16:19:49,856 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) JBAS014613: Operation ("add") failed - address: ([ ("subsystem" => "datasources"), ("data-source" => "DerbyDS") ]) - failure description: {"JBAS014771: Services with missing/unavailable dependencies" => [ "jboss.data-source.java:/DerbyDS is missing [jboss.jdbc-driver.org_apache_derby]", "jboss.driver-demander.java:/DerbyDS is missing [jboss.jdbc-driver.org_apache_derby]" ]} 16:19:49,866 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) JBAS014613: Operation ("add") failed - address: ([ ("subsystem" => "datasources"), ("data-source" => "DerbyDS") ]) - failure description: { "JBAS014771: Services with missing/unavailable dependencies" => [ "jboss.data-source.java:/DerbyDS is missing [jboss.jdbc-driver.org_apache_derby]", "jboss.driver-demander.java:/DerbyDS is missing [jboss.jdbc-driver.org_apache_derby]" ], "JBAS014879: One or more services were unable to start due to one or more indirect dependencies not being available." => { "Services that were unable to start:" => [ "jboss.data-source.reference-factory.DerbyDS", "jboss.naming.context.java.DerbyDS" ], "Services that may be the cause:" => ["jboss.jdbc-driver.org_apache_derby"] } } 16:19:49,897 INFO  [org.jboss.as.server] (ServerService Thread Pool -- 28) JBAS018559: Deployed "MyApp.ear" (runtime-name : "MyApp.ear")

      Do you know what I did wrong?

      Thanks in advance

          I finally solved the issue by :

           

          • adding derbyclient.jar in the standalone directory (where my applications are deployed)

           

          • modifying the datasource declaration in the standalone.xml to make it reference the jar name :

           

          <datasource jndi-name="java:/DerbyDS" pool-name="DerbyDS" enabled="true" use-ccm="false">

                              <connection-url>jdbc:derby:MyDB;create=true</connection-url>

                              <driver>derbyclient.jar</driver>

                              ...

          (I deleted the <drivers> tag, I don't use it anymore.)

           

           

          So, I don't have errors anymore when I start WildFly. The derby driver is not declared as a module, but it will be shared among my different applications, so that's ok.
