WildFly 8.1.0.Final上Firebird数据源的“无法加载模块”错误

Question

The server startup error message is:

16:08:37,829 ERROR [org.jboss.as.controller.management-operation] (ServerService
 Thread Pool -- 27) JBAS014613: Operation ("add") failed - address: ([
    ("subsystem" => "datasources"),
    ("jdbc-driver" => "firebird")
]) - failure description: "JBAS010441: Failed to load module for driver [org.fir
ebirdsql]"

Content of module.xml :

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="org.firebirdsql">
  <resources>
    <resource-root path="jaybird-2.2.5.jar"/>
  </resources>
  <dependencies>
    <module name="javax.api"/>
    <module name="javax.resource"/>
    <module name="javax.transaction.api"/>
  </dependencies>
</module>

Driver definition in standalone.xml :

<driver name="firebird" module="org.firebirdsql">
  <driver-class>org.firebirdsql.jdbc.FBDriver</driver-class>
</driver>

(Based on http://masterjboss.blogspot.de/2014/03/how-to-configure-mysql-jdbc-driver-in.html )

Answer 1

在依赖项部分中将<module name="javax.resource"/>替换为<module name="javax.resource.api"/> 。

Answer 2

I have installed WildFly 8.1 and added the module under:

<wildfly-root>\modules\org\firebirdsql\main\
                                            module.xml
                                            jaybird-2.2.5.jar

Note that this doesn't match the location used in the tutorial you link to. The tutorial - incorrectly - roots user modules in modules\\system\\layers\\base instead of modules\\ , but when I place the module there it works as well.

My module.xml definition has content:

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="org.firebirdsql">
  <resources>
    <resource-root path="jaybird-2.2.5.jar"/>
  </resources>
  <dependencies>
    <module name="javax.api"/>
    <module name="javax.transaction.api"/>
    <module name="javax.resource.api"/>
  </dependencies>
</module>

I added the driver entry to standalone.xml exactly as you posted. And then added a datasource in the management console, and tested the connection.

This works. My earlier theory in the comments that it isn't working for you due to the Web Profile not including Resource Connectors seems to be wrong. I have also tested using a Java 8 version of Jaybird when WildFly is running on Java 7, but this gives an UnsupportedClassVersionError as expected.

The only way I have been able get the error in your question is to intentionally misplace the module (eg deleting it entirely, having a spelling error in the folder names, or putting it in the wrong location). I would suggest that you carefully check your module location (see above).

See the answer by asohun for the solution to your specific problem. I will leave this answer in place as it contains the correct config and an alternative failure mode that produces the same error.
