# FX Professional JNDI configuration

This page lists the JNDI environment entries that must be present in FX Professional’s J2EE web container context.

FX Professional’s deployment descriptor (`web.xml`) contains definitions for the full set of required JNDI entries. The environment values in the deployment descriptor are not suitable for production use, and you must override these values in the web container context as part of deploying FX Professional.

## JNDI environment entries

If any of the JNDI environment entries below are missing from the J2EE web container’s context, then FX Professional will raise an error.

* **CAPLIN.DEV.MODE**\
**Datatype:** `java.lang.String`, **Default:** `false`

  Set to true to allow a liberator host and port to be specified at run time in the query string of the web application URL like this: `?liberatorHost=lib3.example.com&liberatorPort=18081`

  **❗ IMPORTANT**\
  Do not enable CAPLIN.DEV.MODE in production environments.
* **CAPLIN.LOGIN.ENABLED**\
**Datatype:** `java.lang.String`, **Default:** `true`

  Enable FX Professional’s built-in login page.
* **CAPLIN.LOGOUT.REDIRECT**\
**Datatype:** `java.lang.String`, **Default:**

  The login page URL to redirect unauthenticated users to.
* **CAPLIN.LOGOUT**\
**Datatype:** `java.lang.String`, **Default:** `/logout`, **Since:** FX Professional 3.30

  The URI of your logout endpoint.
* **LIBERATOR.DOMAIN**\
**Datatype:** `java.lang.String`, **Default:** `caplin.com`

  Domain on which the Liberator servers are deployed.
* **LIBERATOR.PRIMARY.ADDRESS**\
**Datatype:** `java.lang.String`, **Default:** `localhost`

  Fully-qualified hostname of the primary Liberator server.
* **LIBERATOR.PRIMARY.PORT**\
**Datatype:** `java.lang.String`, **Default:** `18080`

  Primary port of the primary Liberator server.
* **LIBERATOR.PRIMARY.HTTPS.PORT**\
**Datatype:** `java.lang.String`, **Default:** `18081`

  HTTPS port of the primary Liberator server.
* **LIBERATOR.SECONDARY.ADDRESS**\
**Datatype:** `java.lang.String`, **Default:** `localhost`

  Fully-qualified hostname of the secondary (failover) Liberator server.
* **LIBERATOR.SECONDARY.PORT**\
**Datatype:** `java.lang.String`, **Default:** `18080`

  Primary port of the secondary (failover) Liberator server.
* **LIBERATOR.SECONDARY.HTTPS.PORT**\
**Datatype:** `java.lang.String`, **Default:** `18081`

  HTTPS port of the secondary (failover) Liberator server.
* **KEYMASTER.LOCATION**\
**Datatype:** `java.lang.String`, **Default:** `servlet/StandardKeyMaster`

  The URL of the KeyMaster servlet. The URL can be absolute or relative.
* **SESSION.POLL.LOCATION**\
**Datatype:** `java.lang.String`, **Default:** `servlet/Poll`

  The URL of the KeyMaster poll servlet. The URL can be absolute or relative.
* **caplin.keymaster.privatekey.filename**\
**Datatype:** `java.lang.String`, **Default:** `/WEB-INF/cfg/keymaster/privatekey.pem`

  Name of the private key that the KeyMaster servlet uses to sign authentication tokens.
* **TRANSLATIONS_DIR**\
**Datatype:** `java.lang.string`, **Default:** (none), **Since:** FX Professional 3.27.0

  Optional path to an external directory containing translation files that override the default translations in the WAR.   

  Translation filename format: `<locale>.properties`, where `<locale>` is a two-letter country code in lower case. For example, `en.properties`.

  The translation files are served by the web application’s i18n servlet and are requested by FX Professional at startup. The i18n servlet monitors the translation files for changes and always serves the latest versions. After changes are made to a translation file, users see the new localised text when they next sign in.

## Example configuration for Tomcat

This section shows `Environment` entries in an example or an FX Professional web-application context in Apache Tomcat.

The `override` attribute of each `Environment` element is set to `false` to prevent the `value` attribute from being overridden by an equivalent environment entry in FX Professional’s web application deployment descriptor (`web.xml`). For more information on the `override` attribute, see [The Context Container](https://tomcat.apache.org/tomcat-7.0-doc/config/context.html) on the Apache Tomcat website.
