How to switch from default H2 DB of jBPM to another Database like MariaDB?

I've installed MariaDB connector in jBPM 7.53 Final with .jar file and configured MariaDB database locally. Checked in management console and saw that datasources and JDBC connectors look good (MariaDBDS is enabled), but an error showing in runtime "Boot errors occurred during the start of server".
Failure description: {"WFLYCTL0412: Required services that are not
installed:" =>
["jboss.jdbc-driver.mariadb-java-client-2_7_1_jar"],"WFLYCTL0180:
Services with missing/unavailable dependencies" =>
["jboss.driver-demander.java:jboss/MariaDBDS is missing
[jboss.jdbc-driver.mariadb-java-client-2_7_1_jar]","org.wildfly.data-source.MariaDBDS

I have configured MariaDB Java connector in the jBPM standalone.xml
<subsystem xmlns="urn:jboss:domain:datasources:5.0">
<datasources>
<datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">
<connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url>

<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
</driver>
</drivers>
</datasources>
</subsystem>
and I have copied the MariaDB Java connector to JBPM_HOME/modules/com/mariadb/main/mariadb-java-client-2.7.1.jar and configured the module.xml like this:
<module xmlns="urn:jboss:module:1.1" name="org.mariadb">
<resources>
<resource-root path="mariadb-java-client-2.7.1.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
Also, in Business-Central to new process instance appeared this attention:

What I am missing or change in these steps? Any idea if jBPM works with the external DB or not?

#KrenarR have you set up these properties under system-properties as well?
<property name="org.kie.server.persistence.ds" value="java:jboss/MariaDBDS"/>
<property name="org.kie.server.persistence.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>
You can also add the driver as a core module by means of jboss_cli:
module add --name=org.mariadb --resources=mariadb-java-client-2.7.1.jar --dependencies=javax.api,javax.transaction.api
Also check this line in the datasource:
<driver>mariadb-java-client-2.7.1.jar</driver>
I think it should be just the driver name you have defined:
<driver>mariadb</driver>

You can refer to the documentation Switch to another database
from jbpm.org for detailed steps.

connection pool on jboss 7.0.2 don't work

I trying to do a pool connection on JBoss, I saw many things on the internet about this, but nothing work....
<?xml version="1.0" encoding="UTF-8"?>
<subsystem xmlns="urn:jboss:domain:datasources:1.0">
<datasources>

<xa-datasource-class>com.microsoft.sqlserver.jdbc.SQLServerDriver</xa-datasource-class>
</driver>
</drivers>
</datasources>
</subsystem>
when I enter on JBoss admin db_test don't apear
what is worng?

Please refer the link.
https://access.redhat.com/documentation/en-US/JBoss_Enterprise_Application_Platform/6/html/Administration_and_Configuration_Guide/Example_Microsoft_SQLServer_Datasource1.html
Select appropriate database drivers and you will get the correct configuration.
Following is the configuration for MS SQL Server
The example below is a Microsoft SQLServer datasource configuration. The datasource has been enabled, a user has been added, and validation options have been set.
<datasources>
<datasource jndi-name="java:/MSSQLDS" pool-name="MSSQLDS">
<connection-url>jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=MyDatabase</connection-url>
<driver>sqlserver</driver>
<security>
<user-name>admin</user-name>
<password>admin</password>
</security>
<validation>
<valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.mssql.MSSQLValidConnectionChecker"></valid-connection-checker>
</validation>
</datasource>
<drivers>
<driver name="sqlserver" module="com.microsoft">
<xa-datasource-class>com.microsoft.sqlserver.jdbc.SQLServerXADataSource</xa-datasource-class>
</driver>
</datasources>
================================================================================
The example below is a module.xml file for the Microsoft SQLServer datasource above.
================================================================================
<module xmlns="urn:jboss:module:1.1" name="com.microsoft">
<resources>
<resource-root path="sqljdbc4.jar"/>

How to get JBOSS'S datasources programmatically

I am using JBOSS 7.0 application server. I have declared my datasources in standalone.xml as follows,
<datasource jndi-name="java:jboss/datasources/ltmsfleettrackingds" pool-name="ltmsfleettrackingdspool" enabled="true" jta="true" use-java-context="true" use-ccm="true">
<connection-url>
jdbc:mysql://localhost:3306/fleettrackingdb?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf-8
</connection-url>
<driver>
mysqldriver
</driver>
<transaction-isolation>
TRANSACTION_READ_COMMITTED
</transaction-isolation>
<pool>
<min-pool-size>
10
</min-pool-size>
<max-pool-size>
50
</max-pool-size>
<prefill>
true
</prefill>
<use-strict-min>
false
</use-strict-min>
<flush-strategy>
FailingConnectionOnly
</flush-strategy>
</pool>
<security>
<user-name>
root
</user-name>
<password>
</password>
</security>
<validation>
<validate-on-match>
false
</validate-on-match>
<background-validation>
false
</background-validation>
<useFastFail>
false
</useFastFail>
</validation>
<statement>
<prepared-statement-cache-size>
100
</prepared-statement-cache-size>
<share-prepared-statements/>
</statement>
</datasource>
Is it possible to get the mentioned datasource jndi name declared in standalone.xml programmatically in java language.

Add new Datasource (mysql) wildfly

I'm trying to add new datasource mysql jdbc driver to my wildfly server
I created folder wildfly.x.x.x/modules/system/layers/base/com/mysql/main
I've got here jdbc jar file and module.xml
<module xmlns="urn:jboss:module:1.3" name="com.mysql">
<resources>
<resource-root path="mysql-connector-java-5.1.34-bin.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
</dependencies>
</module>
then added dataresource code into standalone-full.xml (under datareources tag)
<datasource jndi-name="java:jboss/datasources/MySQLDS" pool-name="MySQLDS" enabled="true" use-java-context="true">
<connection-url>jdbc:mysql://localhost:3306/test</connection-url>
<driver>MySQLDriver</driver>
<security>
<user-name>root</user-name>
<password></password>
</security>
</datasource>
but when i go to wildfly control panel http://localhost:9990/console/
dataresource doesnt appear , what did i missed?
also i'm trying to add it manually from interface i'v got this error
Unexpected HTTP response: 500
Request
{
"address" => [
("subsystem" => "datasources"),
("data-source" => "mysql")

"failure-description" => "JBAS010440: failed to invoke operation: JBAS010447: Connection is not valid",

}

Did you add a driver definition? Your datasources subsystem should look something like this:
<subsystem xmlns="urn:jboss:domain:datasources:2.0">
<datasources>
<datasource jndi-name="java:/jdbc/myds" pool-name="myds" enabled="true" use-java-context="true">
<connection-url>jdbc:mysql://localhost/mydb</connection-url>
<driver>mysql</driver>
<security>
<user-name>foo</user-name>
<password>bar</password>
</security>
</datasource>
<drivers>
<driver name="h2" module="com.h2database.h2">
<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
</driver>
<driver name="mysql" module="com.mysql">
<xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>
</driver>
</drivers>
</datasources>
</subsystem>
The driver element in the data source definition must reference a driver element by name. The module attribute must match the name of your MySQL driver module.

Actually I meet the same problem (I could add the datasources and test connection successfully before) So I'm just confused and I find a way works for me:)
See my services and I find it stopped,and I started it then tried again,It works well again! Even though your service does not stop, maybe just restart it.
I have to say it may not work for you if you never success to connect before,good luck~

There are three ways using which you can simply create datasource into wildfly
Using admin console
Manually adding into standalone.xml
Creating datasource file that is xml file.
Go to WildFly directory/standalone/deployments
Simplest way to create datasource xml with following content
<datasources xmlns="http://www.jboss.org/ironjacamar/schema">
<datasource jndi-name="APP_DS" pool-name="APP_DS" enabled="true" use-ccm="false">
<connection-url>jdbc:mysql://localhost:3306/DB_NAME</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<driver>mysql</driver>
<!-- sql to call when connection is created -->
<new-connection-sql>SELECT 1</new-connection-sql>
<pool>
<min-pool-size>5</min-pool-size>
<max-pool-size>50</max-pool-size>
</pool>
<security>
<user-name>username</user-name>
<password>password</password>
</security>
<!-- sql to call on an existing pooled connection when it is obtained from pool -->
<validation>
<check-valid-connection-sql>SELECT 1</check-valid-connection-sql>
</validation>
<timeout>
<blocking-timeout-millis>300000</blocking-timeout-millis>
<idle-timeout-minutes>5</idle-timeout-minutes>
</timeout>
<statement>
<track-statements>true</track-statements>
</statement>
</datasource>
</datasources>

Also create the database that you will use. Sometimes the reason for this error is that the database is missing.

Adding pooled connection datasource in JBoss 7

I am changing from Glassfish to Jboss 7. I have configured a datasource in the Glassfish server which is pooled at the server, but not XA. I am trying this, but each time I open admin web gui the driver element is truncated to <driver name="postgresql" .. />. Something must be wrong since I can't log on to my application. How can I configure a datasource which is pooled on JBoss 7?
<drivers>
<driver name="postgresql" module="org.postgresql">
<datasource-class>org.postgresql.ds.PGConnectionPoolDataSource</datasource-class>
</driver>
</drivers>
This is the module.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"/>
</dependencies>
</module>

In you domain.xml/standalone.xml you can specify your datasource:
<subsystem xmlns="urn:jboss:domain:datasources:1.1">
<datasources>
<datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">
<connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1</connection-url>
<driver>h2</driver>
<security>
<user-name>sa</user-name>
<password>sa</password>
</security>
</datasource>
<drivers>
<driver name="h2" module="com.h2database.h2">
<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
</driver>
</drivers>
</datasources>
</subsystem>
