I'm reading the examples from here, and I found an interesting piece:
<datasources>
<datasource jndi-name="java:jboss/PostgresDS" pool-name="PostgresDS">
<connection-url>jdbc:postgresql://localhost:5432/postgresdb</connection-url>
<driver>postgresql</driver>
<security>

<exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLExceptionSorter"></exception-sorter>
</validation>
</datasource>
<drivers>
<driver name="postgresql" module="org.postgresql">
<xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
</driver>
</drivers>
</datasources>
It's not a xa-datasource, but the driver is declaring a xa-datasource-class apontando using org.postgresql.xa.PGXADataSource.
Why not use org.postgresql.Driver? What are the diferences? And why not use driver-class instead of xa-datasource-class?

I am using WildFly 11, I am trying to understand when we configure a data source with a specific driver and we don't set the data source class name explicitly, which actual implementation of javax.sql.DataSource does WF ends up using ?
<datasource jndi-name="java:jboss/datasources/myDB" pool-name="myDB" enabled="true" use-java-context="true" spy="false">
<connection-url>jdbc:mysql://localhost:3306/db?useUnicode=true&characterEncoding=utf8&useSSL=false</connection-url>

</datasource>
my application certainly works and I can see the interaction with the DB just fine, however I am not sure which actual datasource implementation is in use, I tried to configure a logger against MySQL packages that contains the default data sources, but nothing seems to get logged as a result.
WildFly is using ironjacamar (http://www.ironjacamar.org/) as its datasource implementation.
I'm migrating some projects from JBoss 6.4 to JBoss 7.2, these projects needs different datasources to configurate DB connections. I added the datasources to the JBoss server config file (standalone.xml):

Can someone give me and advice?
It is obviously caused by the fact that the listener was not accepting connections, Could you connect your database through sqlplus? Also, you can navigate through the Jboss admin console/localhost:9990 by default/ and click test connection button to check your configuration. Maybe your database client version and DB version are not compatible. You may have connection leak that means there is no room for your pool size of respective datasource or at the database. And check out this link http://www.dba-oracle.com/sf_ora_12519_tns_no_appropriate_service_handler_found.htm
I am trying to use postgres with keycloak. following Doc

The error i am getting.
error
06:13:39,430 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 32) WFLYCTL0013: Operation ("add") failed - address: ([

("jdbc-driver" => "postgresql")
]) - failure description: "WFLYJCA0115: Module for driver [org.postgresql] or one of it dependencies is missing: [org.postgresql]"
How can i resolve this?
Can I suggest another way to configure this that is less likely to have an issue? I use the following to configure PostgreSQL and Keycloak and it has been working well. The key is to run this against a stopped Keycloak (using a fresh install). Save the below to something like setup-keycloak.cli:
embed-server --server-config=standalone.xml --std-out=echo
batch
#
# remove the default provided datasource
#
/subsystem=datasources/data-source=KeycloakDS/:remove
#
# add them
#
module add --name=org.postgres --resources=/path/to/postgresql-42.2.10.jar --dependencies=javax.api,javax.transaction.api
/subsystem=datasources/jdbc-driver=postgres:add(driver-name="postgres",driver-module-name="org.postgres",driver-class-name=org.postgresql.Driver)
/subsystem=datasources/data-source=KeycloakDS/:add(connection-url=jdbc:postgresql://localhost:5432/keycloak_database,driver-name=postgres,jndi-name=java:jboss/datasources/KeycloakDS,initial-pool-size=4,max-pool-size=64,min-pool-size=4,password=keycloak_user,user-name=keycloak_pass)
run-batch
Then run this with $KEYCLOAK_HOME/bin/jboss.sh --file=setup-keycloak.cli. This removes the KeycloakDS datasource, adds the PostgreSQL module, and recreates the KeycloakDS datasource with your parameters. You can use this to reproduce the configuration any time as long as you have a local copy of the PostgreSQL JDBC driver.
I think your problem is that you named the settings config.xml and should be module.xml.
Second you have to download postgresql jar to that location:
curl -O https://jdbc.postgresql.org/download/postgresql-X.X.X.jar > /opt/keycloak/modules/system/layers/keycloak/org/postgresql/main
just replace the X.X.X with your version.
Then restart the server.
PS: you should use a vault for your password.
This works for me.
create PostgreSQL module.xml (not config.xml) inside base directory (keycloak-11.0.2/modules/system/layers/base/com/postgresql/)
update standalone.xml
<datasource jndi-name="java:jboss/datasources/KeycloakDS" pool-name="KeycloakDS" enabled="true" use-java-context="true"

I've got some issues with MySQL module my local JBoss.
In $JBOSS_HOME I created com/mysql/main
There, I dropped mysql-connector-java-5.1.26-bin.jar and module.xml
I then configured my datasource.
In the Netbeans project, persistence.xml was configured as attached via the Persistence Unit wizard and Netbeans automatically recognizes the configured datasource which is cool.
The issue now is that when I want to "Create Entity Classes From Database", I get this error.
I've checked all over the web. I think I have a good config but this error still persists.
Netbeans: 7.3.1; Mysql connector: 5.1.26; App Server: JBoss EAP 6.1.0; Mysql: 5.6.14; Windows 7; Java 7
Kindly advise.
Thanks.
In $JBOSS_HOME I created com/mysql/main There, I dropped mysql-connector-java-5.1.26-bin.jar and module.xml
Can you make sure the folder is under $JBOSS_HOME/modules location
