Appendix B: Application Properties

This appendix describes all available application properties in alphabetical order.

cuba.additionalStores

Default value: anonymous

Stored in the database.

Interface: ServerConfig

cuba.automaticDatabaseUpdate

Determines whether server should run DB update scripts at application start.

Default value: false

{language_code} – corresponds to language code returned by the Locale.getLanguage() method. Used as a suffix for message pack file names. For example, messages_fr.properties.

The first language listed in the cuba.availableLocales property will be selected in the list of available languages by default if the list does not contain the user’s operating system language. Otherwise, user’s operating system language will be selected by default.

Default value: English|en;Russian|ru;French|fr

Interface: GlobalConfig

Used in all standard blocks.

cuba.backgroundWorker.maxActiveTasksCount

Interface: ClientConfig

Used in Web Client.

cuba.bruteForceProtection.enabled

Enables a mechanism for the protection against password brute force cracking.

Default value: false

Stored in the database.

Interface: ServerConfig

Used in the Middleware block.

Default value: 5

Stored in the database.

Interface: ServerConfig

Used in the Middleware block.

cuba.checkPasswordOnClient

When set to false (which is the default), LoginPasswordLoginProvider of the client block sends user’s password as is to the middleware AuthenticationService.login() method. This is appropriate if the client and middleware blocks are co-located in the same JVM. For a distributed deployment when the client block is located on a different computer on the network, the connection between the client and middleware in this case should be encrypted using SSL.

If set to true, LoginPasswordLoginProvider loads the User entity by the entered login and checks the password itself. If the password matches the loaded password hash, the provider performs login as a trusted client using the password specified in the cuba.trustedClientPassword property. This mode saves you from setting up SSL connections between clients and middleware in trusted networks, and at the same time does not exposes user passwords to the network: only hashes are transmitted. However notice that trusted client password is still transmitted over the network, so the SSL-protected connection is still more secure.

Default value: CUBA.Platform

Interface: ServerConfig

Used in the Middleware block.

cuba.numberIdCacheSize

When an instance of entity inherited from BaseLongIdEntity or BaseIntegerIdEntity is created in memory via Metadata.create() method, an identifier value is assigned to the entity right away. This value is obtained from the mechanism that fetches the next id from a database sequence. In order to reduce the number of middleware and database calls, the sequence’s increment is set by default to 100, which means that the framework obtains the range of ids on each invocation. So it "caches" this range and yields the ids without going for the next value to the database until the whole range is used.

The property defines the sequence’s increment and the corresponding size of the cached range in memory.

If you change the value of this property when there are already some entities in the database, recreate also all existing sequences with the new increment (which must be equal to cuba.numberIdCacheSize) and the starting values corresponding to the maximum values of existing ids.

Do not forget to set the property on all blocks used in the application. For example, if you have Web Client, Portal Client and Middleware, you should set the same value in web-app.properties, portal-app.properties and app.properties.

  • If the User entity instance has a language attribute defined, the system will use this language.

  • If the user’s operating system language is included in the list of available locales (set by the cuba.availableLocales property), the system will use this language.

  • Otherwise, the system will use the first language defined in the cuba.availableLocales property.
