Properties¶

Under the etc/ directory in both the source and the binary distributions, several files are provided which help to configure OMERO.server:

etc/omero.properties: Since 5.5, the following repositories now have a properties file with the properties used in the repository itself. See omero-model.properties, omero-common.properties, omero-server.properties, omero-blitz.properties.
etc/hibernate.properties: Required by Hibernate since some properties are only configurable via a classpath:hibernate.properties file
etc/logback.xml: Logging configuration
etc/build.properties: The properties that you will most likely want to change
etc/local.properties: Local file overriding etc/build.properties (used by build only)

The most useful of the properties are listed in a glossary.

On creation of an OmeroContext, the lookup for properties is (first wins):

Properties passed into the constructor (if none, then the default properties in config.xml)
System.properties set via “java -Dproperty=value”
Configuration files in order listed.

This ordering is defined for the various components via “placeholder configurers” in the following file in omero-server:

Once configured at start, all values declared in one of the mentioned ways can be used in Spring configurations via the syntax:

<bean id=…>
  <property name="mySetter" value="${property.name}"/>
</bean>
