```
public class AS400
extends java.lang.Object
implements java.io.Serializable
```
Represents the authentication information and a set of connections to the IBM i host servers.
If running on IBM i or an older version of that operating system, the system name, user ID, and password do not need to be supplied. These values default to the local system. For the system name, the keyword localhost can be used to specify the local system. For the user ID and password, *CURRENT can be used.
If running on another operating system, the system name, user ID, and password need to be supplied. If not supplied, the first 'open' request associated with this object will trigger a prompt to the workstation user. Subsequent opens associated with the same object will not prompt the workstation user. Keywords localhost and *CURRENT will not work when running on another operating system.
For example:
```
    AS400 system = new AS400();
    system.connectService(AS400.DATAQUEUE);   // This causes a password prompt.
    ...
    system.connectService(AS400.FILE);        // This does not cause a prompt.
 
```

```
public boolean isConnected()
```
    Indicates if any service is currently connected through this object.
    A service is considered "connected" if connectService() has been called, or an implicit connect has been done by the service, and disconnectService() or disconnectAllServices() has not been called. If the most recent attempt to contact the service failed with an exception, the service is considered disconnected.
    
    Returns:
    true if any service is connected; false otherwise.
    See Also:
    isConnectionAlive()
  - isConnected
```
public boolean isConnected(int service)
```
    Indicates if a service is currently connected through this object.
    A service is considered "connected" if connectService() has been called, or an implicit connect has been done by the service, and disconnectService() or disconnectAllServices() has not been called. If the most recent attempt to contact the service failed with an exception, the service is considered disconnected.
    Parameters:
    service - The name of the service. Valid services are:
    
    FILE - IFS file classes.
    PRINT - print classes.
    COMMAND - command and program call classes.
    DATAQUEUE - data queue classes.
    DATABASE - JDBC classes.
    RECORDACCESS - record level access classes.

  - isConnectionAlive
```
public boolean isConnectionAlive()
```
    Tests the connection to the system, to verify that it is still working. This is similar in concept to "pinging" the system over the connection. If no services have been connected, this method returns false; it doesn't implicitly connect services.
    Note: This method is not fully supported until IBM i 7.1. If running to IBM i 6.1 or lower, then the behavior of this method matches that of isConnected(), and therefore may incorrectly return true if the connection has failed recently.
    Note: If the only service connected is RECORDACCESS, then this method defaults to the behavior of isConnected().
    
    Returns:
    true if the connection is still working; false otherwise.

  - isMustUseSockets
```
public boolean isMustUseSockets()
```
    When your Java program runs on the system, some Toolbox classes access data via a call to an API instead of making a socket call to the system. There are minor differences in the behavior of the classes when they use API calls instead of socket calls. If your program is affected by these differences you can check whether the Toolbox classes will use socket calls instead of API calls by using this method.
    
    Returns:
    true if you have indicated that the services must use sockets; false otherwise.

    isConnected(int), getDDMRDB()
  - setDefaultSignonHandler
```
public static void setDefaultSignonHandler(SignonHandler handler)
```
    Sets the default sign-on handler, globally across the JVM. The specified handler object will be called at runtime if any AS400 object needs to obtain additional signon information, and a sign-on handler has not been set on the AS400 object via setSignonHandler().
    Users are advised to implement the default sign-on handler in a thread-safe manner, since it may occasionally be in simultaneous use by multiple threads.
    If a default sign-on handler is not set, then the name of the default sign-on handler class is retrieved from the com.ibm.as400.access.AS400.signonHandler system property.
    If not specified, an internal AWT-based sign-on handler is used.
    Note: This property may also be set by specifying a fully-qualified class name in Java system property com.ibm.as400.access.AS400.signonHandler
    
    Parameters:
    handler - The sign-on handler. Specifying null will reset the default sign-on handler to the internal AWT-based handler.
    See Also:
    getDefaultSignonHandler()
  - setDefaultUser
```
public static boolean setDefaultUser(java.lang.String systemName,
                     java.lang.String userId)
```
    Sets the default user for a given system name. The default user is the user ID that is used to connect if a user ID is not provided for that system name. There can be only one default user per system name. Once the default user is set, it cannot be overridden. To change the default user, the caller should remove the default user and then set it.
    
    Parameters:
    systemName - The name of the IBM i system.
    userId - The user profile name.
    
    Returns:
    true if default user has been set; false otherwise.

  - setGSSCredential
```
public void setGSSCredential(java.lang.Object gssCredential)
```
    Sets the GSS credential for this object. Using this method will set the authentication scheme to AUTHENTICATION_SCHEME_GSS_TOKEN. Only one authentication means (Kerberos ticket, profile token, identity token, or password) can be used at a single time. Using this method will clear any previously set authentication information.
    
    Parameters:
    gssCredential - The GSS credential object. The object's type must be org.ietf.jgss.GSSCredential, the object is set to type Object only to avoid a JDK release dependency.
  - setGSSOption
```
public void setGSSOption(int gssOption)
```
    Sets the option for how the JGSS framework will be used to retrieve a GSS token for authenticating to the system. By default, if no password or profile token is set on this object, it will attempt to retrieve a GSS token. If that retrieval fails, a sign-on dialog can be presented, or on the system, the current user profile information can be used. This option can also be set to only do the GSS token retrieval or to skip the GSS token retrieval.
    Parameters:
    gssOption - A constant indicating how GSS will be used. Valid values are:
    
    GSS_OPTION_MANDATORY
    GSS_OPTION_FALLBACK

Using this method will clear any previously set authentication information.
    
    Parameters:
    gssName - The GSS name string.
  - setGuiAvailable
```
public void setGuiAvailable(boolean guiAvailable)
                     throws java.beans.PropertyVetoException
```
    Sets the environment in which you are running. If guiAvailable is set to true, then prompting may occur during sign-on to display error conditions, to prompt for additional information, or to prompt for change password. If guiAvailable is set to false, then error conditions or missing information will result in exceptions. Applications that are running as IBM i applications or want to control the sign-on user interface may want to run with prompting mode set to false. Prompting mode is set to true by default.
    Note: This property may also be set by specifying 'true' or 'false' in Java system property com.ibm.as400.access.AS400.guiAvailable
    
    Parameters:
    guiAvailable - true to prompt; false otherwise.
    
    Throws:
    
    java.beans.PropertyVetoException - If any of the registered listeners vetos the property change.

public void setLocale(java.util.Locale locale)
```
    Sets the Locale used to set the National Language Version (NLV) on the system. Only the COMMAND, PRINT, and DATABASE services accept an NLV. This method will set the NLV based on a mapping from the Locale object to the NLV.
    
    Parameters:
    locale - The Locale object.
  - setLocale
```
public void setLocale(java.util.Locale locale,
             java.lang.String nlv)
```
    Sets the Locale and a specific National Language Version (NLV) to send to the system. Only the COMMAND, PRINT, and DATABASE services accept an NLV.
    
    Parameters:
    locale - The Locale object.
    nlv - The NLV.
  - setMustAddLanguageLibrary
```
public void setMustAddLanguageLibrary(boolean mustAddLanguageLibrary)
```
    Sets this object to attempt to add the appropriate secondary language library to the library list, when running on the system. The default is false. Setting the language library will ensure that any system error messages that are returned, will be returned in the appropriate national language for the client locale. If the user profile has insufficient authority to call CHGSYSLIBL, an error entry will appear in the job log, and the Toolbox will disregard the error and proceed normally.
    Note: This property may also be set by specifying 'true' or 'false' in Java system property com.ibm.as400.access.AS400.mustAddLanguageLibrary
    
    Parameters:
    mustAddLanguageLibrary - true to add language library; false otherwise.
  - isMustAddLanguageLibrary
```
public boolean isMustAddLanguageLibrary()
```
    Indicates whether this object will attempt to add the appropriate secondary language library to the library list, when running on the system.
    
    Returns:
    true if you have indicated that the secondary language library must be added; false otherwise.
  - setMustUseSockets
```
public void setMustUseSockets(boolean mustUseSockets)
```
    Sets this object to using sockets. When your Java program runs on the system, some Toolbox classes access data via a call to an API instead of making a socket call to the system. There are minor differences in the behavior of the classes when they use API calls instead of socket calls. If your program is affected by these differences you can force the Toolbox classes to use socket calls instead of API calls by using this method. The default is false. The must use sockets property cannot be changed once a connection to the system has been established.
    Note: This property may also be set by specifying 'true' or 'false' in Java system property com.ibm.as400.access.AS400.mustUseSockets
    
    Parameters:
    mustUseSockets - true to use sockets; false otherwise.
  - isMustUseNetSockets
```
public boolean isMustUseNetSockets()
```
    Indicates if Internet domain sockets only will be used.
    
    Returns:
    true if must use Internet domain sockets only; false otherwise.
  - setMustUseNetSockets
```
public void setMustUseNetSockets(boolean mustUseNetSockets)
```
    Sets this object to using Internet domain sockets only. When your Java program runs on the system, some Toolbox classes create UNIX domain socket connections. Using this method forces the Toolbox to only use Internet domain sockets. The default is false. The must use net sockets property cannot be changed once a connection to the system has been established.
    Note: This property may also be set by specifying 'true' or 'false' in Java system property com.ibm.as400.access.AS400.mustUseNetSockets
    
    Parameters:
    mustUseNetSockets - true to use Internet domain sockets only; false otherwise.
  - isMustUseSuppliedProfile
```
public boolean isMustUseSuppliedProfile()
```
    Indicates if only a supplied profile will be used.
    
    Returns:
    true if must use a supplied profile only; false otherwise.
  - setMustUseSuppliedProfile
```
public void setMustUseSuppliedProfile(boolean mustUseSuppliedProfile)
```
    Sets this object to using a supplied profile only. When your Java program runs on the system, the information from the currently signed-on user profile can be used. Using this method prevents the Toolbox from retrieving the current user profile information. The default is false. The must use supplied profile property cannot be changed once a connection to the system has been established.

  - setProxyServer
```
public void setProxyServer(java.lang.String proxyServer)
                    throws java.beans.PropertyVetoException
```
    Sets the name and port of the middle-tier machine where the proxy server is running. If this is not set, then the name is retrieved from the com.ibm.as400.access.AS400.proxyServer system property. The ProxyServer must be running on the middle-tier machine.
    The name of the middle-tier machine is ignored in a two-tier environment. If no middle-tier machine is specified, then it is assumed that no middle-tier will be accessed. The name of the middle-tier machine cannot be changed once a connection to this machine has been established.
    
    Parameters:
    proxyServer - The name and port of the proxy server in the format serverName[:port]. If no port is specified, a default will be used.
    
    Throws:
    
    java.beans.PropertyVetoException - If any of the registered listeners vetos the property change.
  - setServicePort
```
public void setServicePort(int service,
                  int port)
```
    Sets the service port in the service port table for the specified service for this system name.
    Parameters:
    service - The name of the service. Valid services are:
    
    FILE - IFS file classes.
    PRINT - print classes.
    COMMAND - command and program call classes.
    DATAQUEUE - data queue classes.
    DATABASE - JDBC classes.
    RECORDACCESS - record level access classes.
    CENTRAL - license management classes.
    SIGNON - sign-on classes.
    port - The port to use for this service. The value USE_PORT_MAPPER can be used to specify that the next connection to this service should ask the port mapper server for the port number.
  - setServicePortsToDefault
```
public void setServicePortsToDefault()
```
    Sets the ports in the service port table for all the services for this system name to their default values. This causes the connections to this system name to use the default ports for those services rather than querying the port number through a port mapper connection. The use of this method can reduce the number of connections made to the system.
  - setShowCheckboxes
```
public void setShowCheckboxes(boolean showCheckboxes)
```
    Indicates if checkboxes should be shown on the sign-on dialog.
    
    Parameters:

  - setSignonHandler
```
public void setSignonHandler(SignonHandler handler)
```
    Sets the sign-on handler for this AS400 object. The specified handler will be called at runtime if the AS400 object needs to obtain additional signon information.
    By default, an internal AWT-based implementation is used, if no sign-on handler has been statically set via setDefaultSignonHandler().
    
    Parameters:
    handler - The sign-on handler. Specifying null will reset the default sign-on handler to the internal AWT-based handler.
    See Also:
    getSignonHandler(), setDefaultSignonHandler(com.ibm.as400.access.SignonHandler)
  - setSocketProperties
```
public void setSocketProperties(SocketProperties socketProperties)

    socketProperties - The set of socket options to set. The options are copied from this object, not shared.
  - setSystemName
```
public void setSystemName(java.lang.String systemName)
                   throws java.beans.PropertyVetoException
```
    Sets the system name for this object. The system name cannot be changed once a connection to the system has been established.
    
    Parameters:
    systemName - The name of the IBM i system. Use localhost to access data locally.
    
    Throws:
    
    java.beans.PropertyVetoException - If any of the registered listeners vetos the property change.
  - setThreadUsed
```
public void setThreadUsed(boolean useThreads)
                   throws java.beans.PropertyVetoException
```
    Sets whether the IBM Toolbox for Java uses threads in communication with the host servers. The default is true. Letting the IBM Toolbox for Java use threads may be beneficial to performance, turning threads off may be necessary if your application needs to be compliant with the Enterprise Java Beans specification. The thread used property cannot be changed once a connection to the system has been established.
    Note: This property may also be set by specifying 'true' or 'false' in Java system property com.ibm.as400.access.AS400.threadUsed
    
    Parameters:
    useThreads - true to use threads; false otherwise.
    
    Throws:

                       throws java.beans.PropertyVetoException
```
    Sets the indicator for whether the default user is used. The default user is used if a system name is provided, but a user ID is not. If a default user is set for that system, then the default user is used.
    
    Parameters:
    useDefaultUser - The value indicating if the default user should be used. Set to true if default user should be used; false otherwise. The default is true, indicating that the default user is used.
    
    Throws:
    
    java.beans.PropertyVetoException - If any of the registered listeners vetos the property change.
  - setUsePasswordCache
```
public void setUsePasswordCache(boolean usePasswordCache)
                         throws java.beans.PropertyVetoException
```
    Sets the indicator for whether the password cache is used. If password cache is used, then the user would only have to enter password once within a Java virtual machine. The default is to use the cache.
    Unless the application is running in its own private JVM, users are advised to turn off password caching, in order to ensure that another application within the same JVM cannot create a connection using the cached password.
    
    Parameters:
    usePasswordCache - The value indicating whether the password cache should be used. Set to true to use the password cache; false otherwise.
    
    Throws:
    
    java.beans.PropertyVetoException - If any of the registered listeners vetos the property change.
  - setUserId
```
public void setUserId(java.lang.String userId)
               throws java.beans.PropertyVetoException
```
    Sets the user ID for this object. The user ID cannot be changed once a connection to the system has been established. If this method is used in conjunction with a Kerberos ticket, profile token, or identity token, the user profile associated with the authentication token must match this user ID.
    
    Parameters:
    userId - The user profile name.
    
    Throws:
    
    java.beans.PropertyVetoException - If any of the registered listeners vetos the property change.
