| Package | Description | 
|---|---|
| java.awt.image | Provides classes for creating and modifying images. | 
| java.math | Provides classes for performing arbitrary-precision integer
 arithmetic ( BigInteger) and arbitrary-precision decimal
 arithmetic (BigDecimal). | 
| java.security.cert | Provides classes and interfaces for parsing and managing
 certificates, certificate revocation lists (CRLs), and
 certification paths. | 
| java.security.interfaces | Provides interfaces for generating RSA (Rivest, Shamir and
 Adleman AsymmetricCipher algorithm)
 keys as defined in the RSA Laboratory Technical Note
 PKCS#1, and DSA (Digital Signature
 Algorithm) keys as defined in NIST's FIPS-186. | 
| java.security.spec | Provides classes and interfaces for key specifications and algorithm
 parameter specifications. | 
| java.sql | Provides the API for accessing and processing data stored in a 
data source (usually a relational database) using the 
JavaTM programming language. | 
| java.text | Provides classes and interfaces for handling text, dates, numbers, and messages
in a manner independent of natural languages. | 
| java.util | Contains the collections framework, legacy collection classes, event model,
date and time facilities, internationalization, and miscellaneous utility
classes (a string tokenizer, a random-number generator, and a bit array). | 
| javax.crypto.interfaces | Provides interfaces for Diffie-Hellman keys as defined in
RSA Laboratories' PKCS #3. | 
| javax.crypto.spec | Provides classes and interfaces for key specifications and algorithm
parameter specifications. | 
| javax.management.openmbean | Provides the open data types and Open MBean descriptor classes. | 
| javax.sql | Provides the API for server side data source access and processing from
the JavaTM programming language. | 
| javax.sql.rowset | Standard interfaces and base classes for JDBC  RowSetimplementations. | 
| javax.sql.rowset.serial | Provides utility classes to allow serializable mappings between SQL types
and data types in the Java programming language. | 
| javax.xml.bind | 
        Provides a runtime binding framework for client applications including
        unmarshalling, marshalling, and validation capabilities. | 
| javax.xml.crypto.dsig.keyinfo | Classes for parsing and processing  KeyInfoelements and structures. | 
| javax.xml.datatype | XML/Java Type Mappings. | 
| org.omg.CORBA | Provides the mapping of the OMG CORBA APIs to the JavaTM
programming language, including the class ORB, which is implemented
so that a programmer can use it as a fully-functional Object Request Broker
(ORB). | 
| org.omg.CORBA.portable | Provides a portability layer, that is, a set of ORB APIs
that makes it possible for code generated
by one vendor to run on another vendor's ORB. |
