4.1.3. Database Access

Any database with a JDBC driver can be used with JOnAS. Sample properties files are provided for
Oracle, InstantDB, Interbase, and PostgreSQL. If you want to setup a new database, you can modify
one of those configuration files to suit your database driver requirements. Here is the PostgreSQL
example:
###################### PostgreSQL DataSource configuration example
#
#####
# DataSource configuration
# Replace db_jonas and jonas by appropriate values.
#
datasource.name
datasource.url
datasource.classname
datasource.username
datasource.password
datasource.mapper rdb.postgres
#####
# ConnectionManager configuration
#
# JDBC connection checking level.
# 0 = no special checking
# 1 = check physical connection is still open before reusing it
# 2 = try every connection before reusing it
jdbc.connchecklevel 1
# Max age for jdbc connections
# nb of minutes a connection can be kept in the pool
jdbc.connmaxage
# Test statement
jdbc.connteststmt select 1
Note that
postgresql_ds
to reference this datasource. Also, if you called this file
jdbc_1
jdbc:postgresql://localhost:5433/db_jonas
org.postgresql.Driver
jonas

is the name that you will have to use in your beans deployment descriptors
