Publish / Find / Bind for EPSG Authority

This page represents the current plan; for discussion please check the tracker link above.

Description

Use of an EPSG Authority implementation in a Java EE container.

  • Need to supply a Hint that an EPSG Authority can use to look up a DataSource using JNDI
  • Create seperate EPSGAuthorityFactory for this use

Status

Initial research completed J2EE and Connection Pools, this first proposal only touches on the use of data source with respect to EPSG Authority.

API Changes

Before this change GeoTools relies on a javadoc comment - to wit: use of the the hard coded JNDI look up String "epsg/authority".

This change involves the introduction of a new Hint to control the lookup string used.

BEFORE

This functionality was based on a documented behaviour - previously the JDBC EPSG Authority implementations would be connected based on:

  • which one was included in the classpath
  • lookup of "epsg/authority" in JNDI

For the above to work only a single epsg authority plugin is allowed to be on the class path, for example "epsg-postgres".

AFTER

We expect the following to work regardless of which epsg authority plugins are included on the classpath.

Example.java

It appears that we should control the "default" (ie when Hints is null) by use of a System property.
