Installing Apache Derby to WildFly
TweetPosted on Saturday Jan 10, 2015 at 02:29PM in Technology
This post describes how to install Apache Derby 10.11.1.1 as Embedded Server to WildFly 8.2.0.Final. following instructions are intended to use with jboss-cli.
- Install jars of Derby as a module into WildFly (assume jar files are located in /tmp)
module add \ --name=org.apache.derby \ --resources=/tmp/derby.jar,/tmp/derbynet.jar,/tmp/derbytools.jar \ --resource-delimiter=, \ --dependencies=javax.api,javax.transaction.api
- Register JDBC Driver named "derby-embedded"
/subsystem=datasources/jdbc-driver=derby-embedded:add(driver-name=derby-embedded, \ driver-module-name=org.apache.derby, \ driver-class-name=org.apache.derby.jdbc.EmbeddedDriver, \ driver-datasource-class-name=org.apache.derby.jdbc.EmbeddedDataSource, \ driver-xa-datasource-class-name=org.apache.derby.jdbc.EmbeddedXADataSource)
- Deploy a MBean which executes the shutdown procedure of Derby
git clone https://github.com/lbtc-xxx/derby-shutdown-service cd derby-shutdown-service; mvn clean package cp target/derby-shutdown-service.jar $WILDFLY_HOME/standalone/deployments
- Define a system property which triggers Derby to listen a port
/system-property=derby.drda.startNetworkServer:add(value=true)
- Define a system property to specify the port Derby will be listening
/system-property=derby.drda.portNumber:add(value="1527")
- Define a system property to specify where log file of Derby will be wrote
/system-property=derby.stream.error.file:add(value="${jboss.server.log.dir}/derby.log")
- Define a system property to append derby.log to exist one
/system-property=derby.infolog.append:add(value="true")
- (For Hibernate user) Add following dependency to
modules/system/layers/base/org/hibernate/main/module.xml
<module name="org.apache.derby"/>
This prevents following warning:WARN [org.hibernate.dialect.DerbyDialect] (ServerService Thread Pool -- 72) HHH000328: Unable to load/access derby driver class sysinfo to check versions : org.apache.derby.tools.sysinfo from [Module "org.hibernate:main" from local module loader @11028347 (finder: local module finder @14899482 (roots: /Users/kyle/servers/wildfly-8.2.0.Final/modules,/Users/kyle/servers/wildfly-8.2.0.Final/modules/system/layers/base))]
- Define a DataSource
- Test connection
/subsystem=datasources/data-source=DerbyEmbeddedDS:test-connection-in-pool
For Regular DataSource:
data-source add \ --name=DerbyEmbeddedDS \ --driver-name=derby-embedded \ --connection-url=jdbc:derby:${jboss.server.base.dir}/derbydata;create=true \ --jndi-name=java:jboss/jdbc/DerbyEmbeddedDS \ --user-name=app \ --password=app
For XA DataSource:
xa-data-source add \ --name=DerbyEmbeddedXADS \ --driver-name=derby-embedded \ --jndi-name=java:jboss/jdbc/DerbyEmbeddedXADS \ --user-name=app \ --password=app \ --same-rm-override=false \ --xa-datasource-properties={ \ "DatabaseName" => "${jboss.server.base.dir}/derbyxadata", \ "CreateDatabase" => "create"}
Also you need to ensure that shutdown script such as /etc/init.d/wildfly
to not execute forcing termination (kill -9
) unexpectedly. it will be triggered by exceed timeout of 30 seconds as default and it may bring database corruption in case that executing force shutdown during shutdown process of Derby. I think that longer timeout would be considerable for poor environment.
References
Works like a charm. Very helpful step-by-step guide. Maybe one last point: I had to restart Wildfly in order to get a "Success" message in the last step (Test connection).
Thanks a lot for this post.
