Method Detail

findConfigDescriptorMatchingEdr

public ConfigDescriptor findConfigDescriptorMatchingEdr(EdrData edr)

Finds a descriptor given the specified Edr.

Parameters:

edr - The Edr data

Returns:

descriptor The descriptor if any

onEdr

public void onEdr(EdrData edr,
                  ConfigDescriptor descriptor)

Handles an EDR. The ConfigDescriptor parameter will be set depending on the following scenarios: (1) If an EdrFilter was specified in register(), it will be null if it does not match the filter; otherwise it will be of the correct subclass. (2) if no EdrFilter was specified in register(), it will be null if it does not match any tag specified by the WLNG; otherwise it will be of the correct subclass.

Parameters:

edr - The EdrData

descriptor - The type of EdrData or null if no EdrFilter specified

onException

public void onException(javax.jms.JMSException jmsException)

Subclasses need to overwrite this method to receive the JMSException if there are any serious connection problems.

Parameters:

jmsException - JMSException

onMessage

public void onMessage(Message message)

processEdr

public void processEdr(EdrData edr)

Processes an individual EdrData object. This method is called by default by the processEdr(EdrData[]) method if it has not been overriden by a subclass.

Parameters:

edr - The EdrData to process

processEdr

public void processEdr(EdrData[] datas)

Processes a batch of EdrData. Can be overriden by a subclass to handle the batch more efficiently. Note: This batch of EdrData is not filtered according to the specified EdrFilter.

Parameters:

datas - The list of EdrData to process

register

public void register(Context context,
                     JMSListener.TYPE type,
                     EdrFilter filter)
              throws Exception

Registers the JMS listener to the EDR topic. The listener can be registered within or outside the WLNG because the EDR topic is available in the JNDI tree.

Parameters:

context - The javax Context

type - Type of registration (see TYPE enum)

filter - An optional EDR filter string

Throws:

Exception - An exception during registration of the listener

register

public void register(String url)
              throws Exception

Registers the JMS listener to the EDR topic. The listener can be registered within or outside the WLNG because the EDR topic is available in the JNDI tree. This method uses the "tag" filtering mechanism.

Parameters:

url - URL of the server where the WLNG is running

Throws:

Exception - An exception during registration of the listener

register

public void register(String url,
                     EdrFilter filter)
              throws Exception

Registers the JMS listener to the EDR topic. The listener can be registered within or outside the WLNG because the EDR topic is available in the JNDI tree.

Parameters:

url - URL of the server where the WLNG is running

filter - An optional EDR filter string

Throws:

Exception - An exception during registration of the listener

register

public void register(String url,
                     JMSListener.TYPE type)
              throws Exception

Registers the JMS listener to the EDR topic. The listener can be registered within or outside the WLNG because the EDR topic is available in the JNDI tree. This method uses the "tag" filtering mechanism.

Parameters:

url - URL of the server where the WLNG is running

type - Type of registration (see TYPE enum)

Throws:

Exception - An exception during registration of the listener

register

public void register(String url,
                     JMSListener.TYPE type,
                     EdrFilter filter)
              throws Exception

Registers the JMS listener to the EDR topic. The listener can be registered within or outside the WLNG because the EDR topic is available in the JNDI tree.

Parameters:

url - URL of the server where the WLNG is running

type - Type of registration (see TYPE enum)

filter - An optional EDR filter string

Throws:

Exception - An exception during registration of the listener

unregister

public void unregister()
                throws JMSException

Unregisters the JMS listener from the Edr topic.

Throws:
