The repository is the location in the file system where all the uploaded files are stored.
When you use image or file properties, the forms generated by JRapid take care of the upload process without any need of manually coding the details. The JRapid application stores all the uploaded files in the directory specified by the repository property.
This property is configured in the jrapid.properties file using the default.repository property. You should not change this property value when running your application in the development environment provided in the JRapid servers.
