首先，您不包括该包，而是包括一个包中的类.您可以使用通配符，因此例如可以使用以下内容:

Firstly you don not include the package, but classes from a package. You can use the wildcard, so for example something like this will work:

import com.plumtree.openfoundation.security.IXPCrypto; // import the single class
import com.plumtree.openfoundation.security.*; // import the entire package

您还需要将jar文件放在您的库路径中.

You also need to have the jar file in your library path.
