javax.jnlp

The JNLP API is designed to provide additional services to JNLP applications running in the Java Plugin or launched by Java Web Start.

Use the ServiceManager to determine which services are available and to gain access to those services.

Since:: 1.4.2

Interface Summary
Interface	Description
BasicService	The `BasicService` interface provides access to the codebase of the application, if an application is run in offline mode, and simple interaction with the native browser on the given platform.
ClipboardService	`ClipboardService` provides methods for accessing the shared system-wide clipboard, even for applications that are running in the untrusted execution environment.
DownloadService	`DownloadService` service allows an application to control how its own resources are cached, to determine which of its resources are currently cached, to force resources to be cached, and to remove resources from the cache.
DownloadService2	Provides cache query services to JNLP applications.
DownloadServiceListener	The `DownloadServiceListener` provides an interface for a callback object implementation, which may be used by a DownloadService implementation.
ExtendedService	`ExtendedService` provides additional support to the current JNLP API, to allow applications to open a specific file or files in the client's file system.
ExtensionInstallerService	The `ExtensionInstallerService` is used by an extension installer to communicate with the JNLP Client.
FileContents	`FileContents` objects encapsulate the name and contents of a file.
FileOpenService	`FileOpenService` service allows the user to choose a file from the local file system, even for applications that are running in the untrusted execution environment.
FileSaveService	`FileSaveService` service allows the user to save a file to the local file system, even for applications that are running in the untrusted execution environment.
IntegrationService	Provides desktop integration for JNLP applications.
JNLPRandomAccessFile	Instances of this class support both reading and writing to a random access file.
PersistenceService	`PersistenceService` provides methods for storing data locally on the client system, even for applications that are running in the untrusted execution environment.
PrintService	`PrintService` provides methods for access to printing functions, even for applications that are running in the untrusted execution environment.
ServiceManagerStub	A `ServiceManagerStub` object implements the particular lookup of JNLP services by the JNLP Client.
SingleInstanceListener	`SingleInstanceListener` is a interface which should be implemented by a JNLP application if they wish to support single instance behaviour.
SingleInstanceService	`SingleInstanceService` allow applications launched under Java Web Start to register themselves as singletons, and to be passed in new parameter sets when user attempts to launch new instances of them.

Class Summary
Class	Description
DownloadService2.ResourceSpec	Specifies patterns for resource queries as arguments and holds results in `DownloadService2.getCachedResources(javax.jnlp.DownloadService2.ResourceSpec)` and `DownloadService2.getUpdateAvailableResources(javax.jnlp.DownloadService2.ResourceSpec)`.
ServiceManager	The `ServiceManager` provides static methods to lookup JNLP services.

Exception Summary
Exception	Description
UnavailableServiceException	The `UnavailableServiceException` is thrown by the `ServiceManager` when a non-existing or unavailable service is looked up.
