Database configuration with WildFly - postgresql

Question

I intend to configure postgresql in my app, but I don't want to manage access to my db through WildFly. Is it possible to avoid this approach and to chose another way but with jndi?

Answer 1

If you want to connect a postgresql database without abstraction layer such as wildFly, you can use simply jdbc (https://jdbc.postgresql.org/about/about.html) :
PostgreSQL JDBC Driver (PgJDBC for short) allows Java programs to
connect to a PostgreSQL database using standard, database independent
Java code. Is an open source JDBC driver written in Pure Java (Type
4), and communicates in the PostgreSQL native network protocol.
If you prefer a lightweight ORM (Object Relational Mapping), I would advise activejdbc (http://javalite.io/activejdbc).

Answer 2

Here you can find the configuration of Wildfly Wildfly datasource configuration . The datasource can be access with jndi. You have to replace the example-jdbc-driver with postgres driver.
Bellow is my example of configuration of datasource for IBM-informix
<datasource jndi-name="java:jboss/datasources/mvpdb" pool-name="mvpdbpool">
<connection-url>jdbc:informix-sqli://mars.bza-intern.de:30020/demomvp:informixserver=tcpmars;DB_LOCALE=de_DE.8859-1;IFX_LOCK_MODE_WAIT=10;</connection-url>
<driver>informix</driver>
<transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
<pool>
<min-pool-size>1</min-pool-size>
<max-pool-size>3</max-pool-size>
<prefill>true</prefill>
</pool>
<security>
<user-name>abcd</user-name>
<password>efgh</password>
</security>
<statement>
<prepared-statement-cache-size>32</prepared-statement-cache-size>
<share-prepared-statements>true</share-prepared-statements>
</statement>
</datasource>
The datasource can be access ( Spring context ):
with Java Configuration
#Bean(name = "mvpds", autowire = Autowire.BY_NAME)
public DataSource Mvpds() {
logger.info("Mvpds-bean");
final JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
dsLookup.setResourceRef(true);
DataSource ds = dsLookup.getDataSource("java:jboss/datasources/mvpdb");
return ds;
}
or XML definition
<bean id="mvpds" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName"><value>java:jboss/datasources/mvpdb</value></property>
</bean>

Answer 3

The question was not correct because of lack of knowledge. The promblem is that no way to configure db without WildFly but with jndi. Jndi is an instrument WildFly uses to find a datasourse:)
