T24: Server Connection Method= INSTANCE is not working

[Arif-ndc]

Hi,

I m configuring T24 browser component (T24.war) to connect to TC
Server. Three files are included in this configuration
i) browserParameters.xml
ii) browserConnection.xml
iii) channels.xml

in browserParameters.xml when i used T24CONNECTOR as Server Connection
Method it works fine but when i used INSTANCE it is not communicating
to Server. [Reason using INSTANCE is that i want to specify two
channels in channel.xml file so that if ther is no response fron one
channel other channel will be tried ]
