## appclient(1)

NAME | SYNOPSIS | DESCRIPTION | INTERFACE STABILITY | OPTIONS | EXAMPLES | SEE ALSO

#### NAME

appclient – launches the Application Client Container and invokes the client application packaged in the application JAR file

#### SYNOPSIS

`appclient` ––client client_application_jar [––mainclass client_application_main_classname| ––name display_name] [––xml sun-acc.xml] [––textauth] [––user username] [––password password]

#### DESCRIPTION

Use the `appclient` command to launch the application client container and invoke a client application that is packaged in an application JAR file. The application client jar file is psecified and created during deployment either by the deploytool or by using the `asadmin` `deploy` command.

The application client container is a set of java classes, libraries and other files that are required to execute a first-tier application client program on a Java Virtual Machine (JVM). The application client container communicates with the Application Server using RMI-IIOP.

The `client.jar` that is retrieved after deploying an application , should be passed with the `-client` option while running the `appclient` utility. The `-mainclass` and `-name` options are optional for a single client application. For multiple client applications use either the `-classname` option or the`- name` option.

#### INTERFACE STABILITY

Sun often provides developers with early access to new technologies, which allows developers to evaluate with them as soon as possible. Unfortunately, new technologies are prone to changes and standardization often results in interface incompatibility from previous versions.

To make reasonable risk assessments, developers need to know how likely an interface is to change in future releases. To aid developers in making these assessments, interface stability information is included on some manual pages for commands, entry-points, and file formats.

The more stable interfaces can safely be used by nearly all applications, because Sun will endeavor to ensure that these continue to work in future minor releases. Applications that depend only on Standard and Stable interfaces should reliably continue to function correctly on future minor releases (but not necessarily on earlier major releases).

The less stable interfaces allow experimentation and proto-typing, but should be used only with the understanding that they might change incompatibly or even be dropped or replaced with alternatives in future minor releases.

"Interfaces" that Sun does not document (for example, most kernel data structures and some symbols in system header files) may be implementation artifacts. Such internal interfaces are not only subject to incompatible change or removal, but we are unlikely to mention such a change in release notes.

#### OPTIONS

`––client`

  required; the name and location for the client application jar file. The application client JAR file is specified and created during deployment, either by the `deploytool` or by the `asadmin deploy` command.

`––mainclass`

  optional; the full classname of the main client application `main()` method that will be invoked by the Application Client Container. Used for a single client application. By default, uses the class specified in the `client jar`. The class name must be the full name. For example, `com.sun.test.AppClient`

`––name`

  optional; the display name for the client application. Used for multiple client applications. By default, the display name is specified in the client jar `application-client.xml` file which is identified by the `display-name` attribute.

`––xml`

  optional if using the default domain and instance, otherwise it is required; identifies the name and location of the client configuration XML file. If not specified, defaults to the value of `$AS_ACC_CONFIG` identified in `asenv.conf` file.

`––textauth`

  optional; used to specify using text format authentication when authentication is needed.

#### EXAMPLES

##### Example 1 Using the `appclient` command

    appclient -client appserv/bin/myclientapp.jar
    -mainclass com.sun.test.TestAppClient -xml sun-acc.xml scott sample

Where: appserv/bin/myclientapp.jar is the full path for the client application `.jar` file, com.sun.text.TestAppClient is the full Java package name of the main client application, `scott` and `sample` are arguments to pass to the application, and sun-acc.xml is the name of the client configuration XML file. If sun-acc.xml is not in the current directory, you must give the absolute path location; otherwise the relative path is used. The relative path is relative to the directory where the command is being executed.
