Deploying Postgresql JDBC into JBoss 7.1.1 Final as a module according to the instructions given in How to connect Jboss-as-7.1.1 with Postgresql .
Created the path $JBOSS_HOME/modules/org/postgresql/main
In $JBOSS_HOME/modules/org/postgresql/main/modules.xml
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.postgresql">
<resources>
<resource-root path="postgresql-9.2-1002.jdbc4.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
<module name="javax.servlet.api" optional="true"/>
</dependencies>
</module>
Into the same directory placed postgresql-9.2-1002.jdbc4.jar
Opened jboss-cli by running $JBOSS_HOME/bin/jboss-cli --connect and ran the command:
/subsystem=datasources/jdbc-driver=postgresql-driver:add(driver-name=postgresql-driver, driver-class-name=org.postgresql.Driver, driver-module-name=org.postgresql)
After it got this error:
Failed to get the list of the operation properties: "JBAS010850: No
handler for operation read-operation-description at address [
("subsystem" => "datasources"),
("jdbc-driver" => "postgresql-driver") ]"
Try to define profile where you want to append a driver. This command appends a new driver in the full profile:
/profile=full/subsystem=datasources/jdbc-driver=postgresql-driver:add(driver-name=postgresql-driver, driver-class-name=org.postgresql.Driver, driver-module-name=org.postgresql)

My setting is the following:
I got an application, which I deploy in /standalone/deployments
The jboss-deployment-structure.xml of my deployment in /standalone/deployments looks the following:
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<dependencies>
[...]
<module name="org.postgresql"/>
</dependencies>
</deployment>
</jboss-deployment-structure>
To drop the jboss-deployment-structure.xml completely (because it must not be used if there are no classloading issues), doesn't work. I use more dependencies (keycloak) beside the driver, which can't be found then.
My module.xml in my module org/postgresql/main looks like this (like described in https://www.keycloak.org/docs/4.8/server_installation/index.html#package-the-jdbc-driver)
<?xml version="1.0" encoding="UTF-8"?>
<module name="org.postgresql" xmlns="urn:jboss:module:1.5">
<resources>
<resource-root path="postgresql-42.2.5.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
My requirement is, to allow different types of jdbc-drivers, e.g. postgres, oracle, mssql.
First option:
I can change my jboss-deployment-structure.xml to
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<dependencies>
[...]
<module name="org.postgresql" optional="TRUE"/>
<module name="com.oracle.ojdbc6" optional="TRUE"/>
[...]
</dependencies>
</deployment>
</jboss-deployment-structure>
(added the optional-parameter)
Then I have to allow all drivers explicitly. Seems to be not the best way.
The idea comes from the standard documentation.
Second option:
I change my module-path to driver/jdbc/main (instead of org/postgres/main) and the module.xml to
<module name="driver.jdbc" xmlns="urn:jboss:module:1.5">
[...]
</module>
(changed name of module)
and go with the module-reference in my jboss-deployment-structure.xml like
<jboss-deployment-structure>
[...]
<module name="driver.jdbc"/>
[...]
</jboss-deployment-structure>
Now I force my customers to name the driver-module like I proposed. They can't name the module like mentioned in every standard-documentation.
The idea comes from this question.
I am doing this in context of a keycloak installation with a self-implemented User-federation to access a separate (legacy) user-database. Therefore dropping the jboss-deployment-structure.xml is no option as mentioned above.
Whats the correct way to achieve my goal of being flexible with the jdbc-driver?
EDIT: mentioned, dropping jboss-deployment-structure.xml is not working.
Keycloak have a very well designed container. You can get inspiration from it for your deployment. Just take a look at how the Dockerfile installs database driver modules and later how to activate those modules using jboss_cli.
Of course, if you can, maybe you can use the container instead. Just make sure to include the module.xml for your driver and activate it on start-up by providing your own entrypoint.
I would suggest you should install all database drivers individually as modules. Individual modules will help you to track and upgrade driver jars easily in the future.
As long as you don't have any classloading problems with your application you don't need to mention these drivers in the jboss-deployment-structure.xml file. They are static modules and will be loaded on server startup.
Moreover, after installing the driver modules, you have to add entries in the standalone.xml file. For example, if I have installed Oracle driver then
<driver name="oracle" module="com.oracle">
<driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
</driver>
within the tag.
Add a datasource definition within the tag (next to ExampleDS):
<datasource jndi-name="java:/[NAME]" pool-name="OracleDS" enabled="true">
<connection-url>jdbc:oracle:thin:#[HOST_NAME]:1521:[SID]</connection-url>
<driver>oracle[has to match the driver name]</driver>
<pool>
<min-pool-size>1</min-pool-size>
<max-pool-size>5</max-pool-size>
<prefill>true</prefill>
</pool>
<security>
<user-name>[USER]</user-name>
<password>[PWD]</password>
</security>
</datasource>
At least I went with a hybrid solution of my two above mentioned approaches for the jboss-deployment-structure.xml like as follows
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<dependencies>
<module name="org.postgresql" optional="TRUE"/>
<module name="com.oracle.ojdbc6" optional="TRUE"/>
[...]
<module name="driver.jdbc" optional="TRUE"/>
</dependencies>
</deployment>
</jboss-deployment-structure>
I listed all the relevant database divers as optional modules and listed another one with flexible naming if a driver is desired, which is not mentioned in the list above.
I am having difficulty installing the postgres driver. I've tried a bunch of things:
https://docs.jboss.org/author/display/WFLY10/Application+deployment
a. tried "deploying" the JAR (both from CLI and admin console UI)
https://sites.google.com/site/jmdstips/jboss-wildfly/postgresql-on-wildfly---xa-datasource
a. tried putting module definition in modules/org/postgresql ...
b. tried putting module definition in modules/system/layers/base/org/postgresql
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="org.postgres">
<resources>
<resource-root path="postgresql-9.4.1212.jre7.jar" />
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
<module name="javax.servlet.api" optional="true"/>
</dependencies>
</module>
And:
<drivers>
<driver name="h2" module="com.h2database.h2">
<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
</driver>
<driver name="postgresql" module="org.postgresql">
<datasource-class>org.postgresql.Driver</datasource-class>
<xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
</driver>
</drivers>
After all of that, I get this error. So, I think wildfly can "see" the module, but something is awry.
23:24:15,889 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 33) WFLYCTL0013: Operation ("add") failed - address: ([
("subsystem" => "datasources"),
("jdbc-driver" => "postgresql")
]) - failure description: "WFLYJCA0041: Failed to load module for driver [org.postgresql]"
short answer: put the driver in the /wildfly/standalone/deployments folder, it will deploy the driver automatically
It turns out I used "org.postgres" for the module name in standalone.xml instead of "org.postgresql" which is what I declared it as inside the module.xml
I also encountered this error and it was due to the module.xml not having the correct resource-root
I'm attempting to add an Oracle DB datasource to Wildfly 10. Here's what I have:
<wildfly-home>\modules\com\oracle\ojdbc6\main\
module.xml
ojdbc6.jar
module.xml
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:Wildfly:module:1.0" name="com.oracle.ojdbc6">
<resources>
<resource-root path="ojdbc6.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.resource.api"/>
<module name="javax.transaction.api"/> <!-- See * below -->
</dependencies>
</module>
* I have tried both with and without the line <module name="javax.transaction.api/>. Some examples I've found online include it. Some do not. It seems to make no difference with whether the error occurs or not.
ojdbc6.jar was copied from <oracle-home>\jdbc\lib\ojdbc6.jar.
I have modified <wildfly-home>\standalone\configuration\standalone.xml to include this within the <drivers> tag:
<driver name="oraclethin" module="com.oracle.ojdbc6">
<xa-datasource-class>oracle.jdbc.xa.client.OracleXADataSource</xa-datasource-class>
</driver>
This error message is being spat out when I cd into <wildfly-home>\bin and run .\standalone.bat:
15:17:13,415 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 33) WFLYCTL0013: Operation ("add") failed - address: ([
("subsystem" => "datasources"),
("jdbc-driver" => "oraclethin")
]) - failure description: "WFLYJCA0041: Failed to load module for driver [com.oracle.ojdbc6]"
I've triple checked the spelling on everything. I've tried taking out some lines (and putting them back when nothing changes). Is anyone seeing what I'm missing?
Use xmlns="urn:jboss:module:1.0"
As described in https://docs.jboss.org/author/display/MODULES/Module+descriptors
what solve the issue for me was to enlarge the timeout connection on the standalone.xml file on jboss
<system-properties>
...
<property name="jboss.as.management.blocking.timeout" value="6000"/>
</system-properties>
I'm trying to deploy an EAR file in my local server but it seems it's still trying to use hibernate 4 (the default option, I guess).
What I have already done:
I've added a hibernate 3 module in $JBOSS_HOME$\modules\org.hibernate\3 with this module.xml file:
<module xmlns="urn:jboss:module:1.0" name="org.hibernate" slot="3">
<resources>
<resource-root path="hibernate3.jar"/>
<resource-root path="commons-collections-3.1.jar"/>
<resource-root path="jta-1.1.jar"/>
<resource-root path="javassist-3.12.0.GA.jar"/>
<resource-root path="antlr-2.7.6.jar"/>
<resource-root path="slf4j-api-1.6.1.jar"/>
<resource-root path="dom4j-1.6.1.jar"/>
<!-- Insert other Hibernate 3 jars to be used here -->
</resources>
<dependencies>
<module name="org.jboss.as.jpa.hibernate" slot="3"/>
<module name="asm.asm"/>
<module name="javax.api"/>
<module name="javax.persistence.api"/>
<module name="javax.transaction.api"/>
<module name="com.ibm.db2" />
<module name="org.infinispan"/>
</dependencies>
</module>
I've created the data source in standalone-full-ha.xml:
<datasource jndi-name="java:jboss/datasources/txdb" pool-name="txdbDS" enabled="true" use-java-context="true">
<connection-url>jdbc:db2://156.24.30.103:50000/TX_LSPDB</connection-url>
<driver>DB2Driver</driver>
<security>
<user-name> .... </user-name>
<password> .... </password>
</security>
</datasource>
My persistence.xml file has the following entry:
<persistence-unit name="esdb">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:jboss/datasources/txdb</jta-data-source>
<class>com.gtech.commerce.UidBlockPool</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.DB2Dialect"/>
<property name="jboss.as.jpa.providerModule" value="org.jboss.as.jpa.hibernate:3" />
</properties>
</persistence-unit>
And this is what I get when I try to deploy:
Caused by: java.lang.ClassCastException: org.springframework.orm.hibernate3.LocalJtaDataSourceConnectionProvider incompatible with org.hibernate.service.jdbc.connections.spi.ConnectionProvider at org.hibernate.service.jdbc.connections.internal.ConnectionProviderInitiator.instantiateExplicitConnectionProvider(ConnectionProviderInitiator.java:189) [hibernate-core-4.2.0.SP1-redhat-1.jar:4.2.0.SP1-redhat-1] ... 107 more
Any idea about what I am missing?
UPDATE: I haven't found a solution, so I did the obvious workaround: I am using hibernate 3 bundled with the application, ignoring any module
Imho the problem comes from the fact that the jboss datasource built-in connection pool rely on the default persistence implementation provided with the server.
you can try to override the server datasource configuration
see https://access.redhat.com/site/documentation/en-US/JBoss_Enterprise_BRMS_Platform/5/html/BRMS_Administrator_Guide/Configuring_a_Datasource_for_JBoss_Enterprise_Application_Platform_6.html
But i don't know if you can specify the connection pool provider.
You could try otherwise to set up a custom datasource
see http://docs.jboss.org/hibernate/orm/4.1/devguide/en-US/html/ch01.html
please consider than you won't be any more in this case: JDBC connections obtained from a JNDI datasource automatically participate in the container-managed transactions of the application server.
and will have to properly configure the transaction factory.
As a more general comment I'll advise not to override provided implementation when using a Java EE application server.
If you wan't to use hibernate 3 switch to Jboss 6.0 or do not rely on the built-in java EE container features (and in this case switch to something lighter like jetty or tomcat)
I'm trying to set up Spring 3.0.6 libraries as a module in JBoss 7.
I have all of the jars in modules/org/springframework/main along with the following module.xml
<module xmlns:"urn:jboss:module:1.0" name="org.springframework">
<resources>
<resource-root path="org.springframework.beans-3.0.6.RELEASE.jar"/>
...
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.servlet.api"/>
<module name="org.apache.commons.logging"/>
</dependencies>
</module>
I added org.springframework to the Dependencies line in my MANIFEST.MF
When I deploy the app the following exception is thrown while parsing my spring-servlet.xml file (sorry, this is from a system that is not networked)
SAXParseException: ... Cannot find the declaration of element 'beans'
My first thought was that the module is not being used but if I remove org.springframework from my Dependencies line it fails to find org.springframework.web.context.ContextLoaderListener
Everything works fine if I put the jars in WEB-INF/lib instead of using the module.
spring-servlet.xml contains the following schema reference
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
so I put spring-beans-3.0.xsd in the same directory as spring-servlet.xml and modified the xml to
http://www.springframework.org/schema/beans spring-beans-3.0.xsd
but still no luck.
Anybody have an idea of why the class files are found but the xsd files are not?
Just in case the link that was given in the comments goes away, the problem is that
Problem:
The namespace configuration files are in META-INF, but that directory
is not visible (nor is it configurable via
jboss-deployment-structure.xml)
Solution:
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">
<deployment>
<dependencies>
<module name="org.apache.commons.logging"/>
<module name="org.springframework" >
<imports>
<include path="META-INF**"/>
<include path="org**"/>
</imports>
</module>
</dependencies>
</jboss-deployment-structure>
Was facing the exact same issue. Had set up a spring module on JBoss 7 and then when deploying my application, was facing the below warning:
Failed to read schema document
'http://www.springframework.org/schema/beans/spring-beans-3.2.xsd'
I understood the spring context file was unable to access the schema definitions from the spring jars, after reading the link in the comments above. And hence, the application was not getting deployed. But the solution given there did not work for me. But the below code in the jboss-deployment-structure.xml resolved the issue.
Solution
<module name="org.springframework.spring" meta-inf="export" export="true" />
Added meta-inf="export" attribute.
