JDBC connection to HDR group (databases)

Folks, IDS11.50 FC8, Redhat Linux. CSDK 3.70 FC1 IBM Informix JDBC Driver Version 3.70.JC1 We tried to use JDBC to conenct to a HDR databases( primary/secondary) . We specified the server as group name ( not primary or secondary server name) for automatic failover purpose( see attached error). Our sqlhosts files has, g_goesr group - - i=26 nsofgoesrp_tcp onsoctcp franklin-dat online9136 g=g_goesr nsofgoesrs_tcp onsoctcp stephanie-dat online9146 g=g_goesr The Connection clause is wrong format ? Any answer?
