Unable to install/run SQL Server driver in WildFly 10

Question

I am running my application on a WildFly 10 server. I do not wish to place my connection details on my application src codes thus am trying to place it inside WildFly 10 server itself.

However I am facing issues.

Under [WILDFLY_HOME]\modules\system\layers\base\com\microsoft, I created the following directory sqlserver\main and I place my JAR file and my XML file inside the main folder.

The JAR that I am using is sqljdbc.jar.

module.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!-- JDBC Drivers module.xml file to configure your JDBC drivers-->

<!-- SQL Server 2014 example -->
<module xmlns="urn:jboss:module:1.3" name="com.microsoft.sqlserver">
  <resources>
    <resource-root path="sqljdbc.jar"/>
  </resources>
  <dependencies>
    <module name="javax.api"/>
    <module name="javax.transaction.api"/>
  </dependencies>
</module>

Next under [WILDFLY_HOME]\standalone\configuration, I modified the standalone.xml. Under the subsystem datasource section, I add the details for SQL Server.

standalone.xml:

<subsystem xmlns="urn:jboss:domain:datasources:4.0">
    <datasources>
        <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">
            <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>
        <datasource jndi-name="java:/TestDS" pool-name="TestDS" enabled="true" use-java-context="true">
            <connection-url>jdbc:sqlserver://localhost\test:1433;databaseName=test</connection-url>
            <driver>mssql</driver>
            <security>
                <user-name>sa</user-name>
                <password>Password123!</password>
            </security>
            <pool>
                <min-pool-size>5</min-pool-size>
                <max-pool-size>50</max-pool-size>
                <prefill>false</prefill>
                <use-strict-min>false</use-strict-min>
                <flush-strategy>FailingConnectionOnly</flush-strategy>
            </pool>
            <validation>
                <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.mssql.MSSQLValidConnectionChecker"></valid-connection-checker>
            </validation>
        </datasource>
        <drivers>
            <driver name="h2" module="com.h2database.h2">
                <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
            </driver>
            <driver name="mssql" module="com.microsoft.sqlserver">
                <xa-datasource-class>com.microsoft.sqlserver.jdbc.SQLServerDriver</xa-datasource-class>
            </driver>
        </drivers>
    </datasources>
</subsystem>

The error that I am facing now is as per below when I start running my WildFly:

15:19:51,098 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([

Answer 1

I managed to resolve the issue with this.

Since I place the file under this directory: [WILDFLY_HOME]\modules\system\layers\base\com\microsoft

Then the correct module location should be as per follow for normal datasource:

<driver name="mssql" module="system.layers.base.com.microsoft.sqlserver">
    <driver-class>com.microsoft.sqlserver.jdbc.SQLServerDriver</driver-class>
</driver>

or

if you are using xa datasource:

<driver name="mssql" module="com.microsoft.sqlserver">
    <xa-datasource-class>com.microsoft.sqlserver.jdbc.SQLServerXADataSource</xa-datasource-class>
</driver>
