Wildfly Required services that are not installed:\

Question

im trying to deploy a JPA rest application and getting the following error trying to deploy on Wildfly 10.

Error:

persistance.xml

<persistence-unit name="app-pu" transaction-type="JTA">
    <jta-data-source>java:/newDevConnection</jta-data-source>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties/>
</persistence-unit>

datasource in standalone.xml

<datasources>
        <datasource jndi-name="java:/newDevConnection" pool-name="secret" enabled="true" use-java-context="true">
            <connection-url>jdbc:mysql://secret...</connection-url>
            <driver>mysql</driver>
            <security>
                <user-name>secret</user-name>
                <password>secret</password>
            </security>
        </datasource>
 <drivers>
        <driver name="com.mysql" module="mysql.mysql-connector-java">
          <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
        </driver>
        <driver name="mysql" module="org.mysql">
            <driver-class>com.mysql.jdbc.Driver</driver-class>
        </driver>
     </drivers>
</datasources>

Edit: mysql jdbc driver is located in project/WEB-INF/lib folder

And what is the difference in an "xa-datasource" and "non-xa-datasource"?

Am i on the right track here? thanks in advance / Marcus

I know it's a year old but in case somebody else hits this question I'll post what I have done for this problem. This took me forever to figure out as new JBOSS Admin.

Short story is the ExampleDS holds a default section in the profile which is where your error is coming from. I normally work with Domain profiles so I'll show the example I have, but Standalone is the same just drop the profile name in front. Default-Bindings is the section in ee subsystem.

<default-bindings context-service="java:jboss/ee/concurrency/context/default" datasource="java:jboss/datasources/ExampleDS" managed-executor-service="java:jboss/ee/concurrency/executor/default" managed-scheduled-executor-service="java:jboss/ee/concurrency/scheduler/default" managed-thread-factory="java:jboss/ee/concurrency/factory/default"/>

The default datasource="java:jboss/datasources/ExampleDS is the source of the problem.

You can remove and set the default DataSource to undefined.

/profile=Profile_NameHere/subsystem=datasources/data- 
 source=ExampleDS:remove()
/profile=Profile_NameHere/subsystem=ee/service=default-bindings:write- 
 attribute(name=datasource,value=undefined)

OR

You can set your own DataSource as the default.

/profile=Profile_NameHere/subsystem=ee/service=default-bindings:write- 
 attribute(name=datasource,value=java\:\/jboss\/datasources/name)
