Jboss EAP7/Wildfly Oracle datasource error: Services with missing/unavailable dependencies - wildfly

Question

I'm using Jboss EAP 7.1 now, recently I add the Oracle datasource to the server as the datasource I correctly configured before. But I got the error message:
Services with missing/unavailable dependencies" => [
"org.wildfly.data-source.CreditDS is missing [jboss.jdbc-driver.oracle11g]"
CreditDs is my JNDI name and oracle11g is the driver name. Here are my configuration:
<!-- standalone.xml -->
<datasource jndi-name="java:jboss/datasources/CreditDS" pool-name="CreditDS" enabled="true">
<connection-url>jdbc:oracle:thin:#***</connection-url>
<driver>oracle11g</driver>
…… …… ……
</datasource>
<drivers>
<driver name="oracle11g" module="com.oracle.ojdbc14">
<xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
</driver>
</drivers>
Here is the modules.xml in modules/com/oracle/ojdbc14/main
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="com.oracle.ojdbc14">
<resources>
<resource-root path="ojdbc14-10.2.0.4.0.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
What's wrong?

Answer 1

I guess your oracle module is not recognized correctly.
The procedure for adding oracle JDBC module is as follows:
1 create folder com/oracle/ojdbc14/10.2.0.4.0 withing JBOSS_HOME/modules directory
2 copy your oracle jar file to the folder and add a module.xml with the following contents
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="com.oracle.ojdbc14" slot="10.2.0.4.0">
<resources>
<resource-root path="ojdbc14-10.2.0.4.0.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
3 Create driver definition in standalone.xml
<driver name="oracle14" module="com.oracle.ojdbc14:10.2.0.4.0">
<xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
</driver>
Couple of things to note:
Do pay attention to correct version of JBoss modules XMLNS - you tagged your questions with EAP7 - so you should use xmlns 1.3.
Note the slot value in both modules.xml and driver definition. This could be any value, but it is a good practice to use the lib version.
After adding any modules into JBoss, you need to restart it completely(restart JVM).
Lastly, you should use an up-to-date version of Oracle JDBC driver as ojdbc14 are not supported anymore, so it should be like this:
Module.xml
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="com.oracle.ojdbc7" slot="12.1.0.2">
<resources>
<resource-root path="ojdbc7-12.1.0.2.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
Folder modules/com/oracle/ojdbc7/12.1.0.2
Driver:
<driver name="oracle7" module="com.oracle.ojdbc7:12.1.0.2">
<xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
</driver>
