Unable to install/run SQL Server driver in WildFly 10 - sql-server

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>
<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>

Answer 2

The driver is wrong, use
<driver name="mssql" module="com.microsoft.sqlserver">
<xa-datasource-class>com.microsoft.sqlserver.jdbc.SQLServerXADataSource</xa-datasource-class>
</driver>
or
<driver name="mssql" module="com.microsoft.sqlserver">
<driver-class>com.microsoft.sqlserver.jdbc.SQLServerDriver</driver-class>
</driver>

Answer 3

You can add sqlserver as global module as shown below
<subsystem xmlns="urn:jboss:domain:ee:4.0">
<global-modules>
<module name="com.microsoft.sqlserver" slot="main"/>
<module name="com.sql.mysql" slot="main"/>
</global-modules>
.
.
</subsystem>
