Used the following to correct the 1st Issue:
RULE catch.DVSRoundRobinScheduling.updateServerConnectionPool
CLASS com.nokia.tpapps.cenotificationservice.nsAlgortihm.scheduling.DVSRoundRobinScheduling
METHOD updateServerConnectionPool
BIND
TPA_LOGGER:Logger = com.alcatel.tpapps.common.common.TPAResources.getLogger();
COMPILE
AT ENTRY
IF ($aInServerList == null || $aInServerList.size() == 0)
DO
$aInServerList = java.util.Arrays.asList(new Object[] {"abc", "xyz", "123"});
TPA_LOGGER.info("[BMAN] DVSRoundRobinScheduling: updateServerConnectionPool aInServerList [" + $aInServerList + "]");
ENDRULE
and it is working.
Need answer to 2nd issue.
