Field Detail

MODE_OFF

public static final short MODE_OFF

Operating mode off means that WfXML is deactivated. It means that incoming requests are not handled. Anyway, outgoing requests can still be sent from this server.

Constant Field Values

MODE_ACTIVE

public static final short MODE_ACTIVE

Operating mode active means that WfXML is fully active. Incoming requests are handled and outgoing requests are sent.

See Also:

Constant Field Values

MODE_PASSIVE

public static final short MODE_PASSIVE

Operating mode passive means that WfXML is activated. Incoming requests are handled but outgoing messages are not sent actively (they require an active communication partner who will request these messages).

Method Detail

requestPartnerStatus

public Page requestPartnerStatus(HttpServletRequest req)
                          throws Exception

This method requests "live" info from a partner and generates a HTML page containing this information. It is called from the Administration.

Parameters:

req - The HTTP request

Returns:

A HTML page containing the information

Throws:

Exception

localStatus

public Page localStatus(HttpServletRequest req)

getPartner

public static Partner getPartner(String id)

Use this method to get a Partner object representing a WfXML communication partner that you know (you must know the id with which the partner has been defined). For enterprise servers, this id is the server id.

Parameters:

id - The id with which the partner has been defined in the enterprise configuration of the local server.

Returns:

A reference to the Partner with the given id, or null if no partner with this id exists.

getAllPartners

public static Partner[] getAllPartners()

This method returns an array containing all defined partners.

Returns:

Array with all defined communication partners. If no partners are defined, the returned array will be empty.

getOperatingMode

public static short getOperatingMode()

Use this method to find out if the local server operates in passive, active, or off mode.

Returns:

A short value representing the operating mode of the local server. This can be one of the constants of this class, e.g., MODE_ACTIVE.

getDomainName

public static String getDomainName()

Returns the fully qualified domain name of the local host, or an empty String if no domain name is available.

Returns:

The domain name or an empty String if no domain name is available.

getPort

public static int getPort()

Returns the port on which the local http server is running. As WfXML messages are sent using the HTTP protocol, also WfXML messages will be received through this port.

Returns:

Port where the local http server is listening for incoming requests.

getContextRoot

public static String getContextRoot()

Use this method to get the context root of the local server. The default value for the context root is wf.

Returns:

The context root of the local server.

getId

public static String getId()

This method returns the id of the local enterprise server. This id is used to identify this server. If you want to add this server to the WfXML configuration of an other enterprise server, you must use this id as id.

Returns:

The id of the local server.

getURI

public static String getURI()

Returns the complete URI to the Receiver's receive method on the local server. The returned value may look similar to:
http://iquitos:8000/wf/servlet.method/com.groiss.wfxml.impl.Receiver.receive/

Returns:

The complete URI to the local WfXML Receiver's receive method.

getVersion

public static String getVersion()

Use this method to find out which version of the WfXML specification is implemented by this implementation.

Returns:

A String representation of the version.

registerMessageListener

public static boolean registerMessageListener(Class<?> listener,
                                              Partner partner)

Use this method to register a message listener that will listen for messages from a specific partner or all partners. If the listener has already been registered for messages from the given partner, nothing will be done and this method returns false indicating that the listener already exists. Otherwise the listener will be registered and true is returned.

Parameters:

listener - The message listener that you want to register.

partner - The listener will be called for all incoming messages of this partner. If you don't provide a partner here (null) the listener will be registered for incoming messages of all partners.

Returns:

true if the listener didn't exist and was inserted now, or false if the listener already existed and nothing was done.

unregisterMessageListener

public static void unregisterMessageListener(Class<?> listener,
                                             Partner partner)

Use this method to remove previously registered message listeners. The following parameter combinations will work:

• no listener (null), no partner (null): All registered listeners for all partners will be removed. Take care, this really removes all message listeneres, so afterwards there will be 0 listeners.
• no partner: the given listener will be removed completely. If it appears for more than one partners, it will be removed for all of them.
• no listener: all listeners that have been registered for incoming messages from the specified partner will be deleted. Listeners that are registered for all partners will not be affected.
• both listener and partner are set: this will remove the given listener if it has been previously registered to listen for requests from the specified partner.

Parameters:

listener - The listener that you want to remove (see text above for more details).

partner - The partner for which you want to remove registered listeners (also see the text above for more details).

dateToWfXMLDate

public static String dateToWfXMLDate(Date date)

Transforms a date to a WfXML date (like specified in the WfXML specification). WfXML dates are in the form YYYY-MM-DDThh:mm:ssZ and always in GMT (Greenwich Mean Time). So this method transforms the given date to this requirements.
For transformations in the other direction, use the wfXMLDateToDate method.

Parameters:

date - A Date object containing a date/time which you want to tranform to WfXML representation

Returns:

a String containing the WfXML representation of the Date object.

wfXMLDateToDate

public static Date wfXMLDateToDate(String dateString)

Transforms a WfXML date to a Java Date object. The WfXML date must be in the specified format YYYY-MM-DDThh:mm:ssZ and in GMT (Greenwich Mean Time). The returned date object will represent the time in the current timezone, depending on where the computer is located. For transformations in the other direction, use the dateToWfXMLDate method.

Parameters:

dateString - A String object containing the WfXML representation of a date/time.

Returns:

A Date object containing the date and time.

Throws:

ApplicationException - if the String dateString is not formatted according to the above mentioned format.

getDefaultUser

public static User getDefaultUser()

getDefaultServer

public static com.dec.avw.core.Server getDefaultServer()

getMaxLogSize

public static int getMaxLogSize()

isLogEnabled
