Configuration Specification Settings
Export uses a configuration specification to determine the data to include in the JAR file. You select the configuration specification in the following manner:
If you select a configuration specification, the configuration specification determines the objects that are exported. That configuration specification is saved as a modifiable default for future export operations.
If you do not select a configuration specification and you are performing an export operation for the first time, the preference for configuration specification determines the objects that are exported. The preference for configuration specification is saved as the modifiable default for future export operations.
If you do not select a configuration specification and you have performed an export operation in the past, the default configuration specification is used. You can modify the default.
