You can create new Cartridge projects in Design Studio. For example, you may create a Cartridge project that contains all characteristics, another that contains all specifications, and so forth. Everything you create in Design Studio (characteristics, specifications, and rule sets, for example) resides in a project. The name you choose for a Cartridge project becomes the name of a JAR file, and everything you create within that project is automatically placed in the JAR file.
See "Creating New Cartridge Projects" for more information about creating cartridge projects in Design Studio.
See "Project Editor" for information about the tabs you use to define an Inventory cartridge project. See "Reviewing the Error Log" and "Problems View" for more information about resolving project errors and warnings.
