Hi anilkumar2508,

The piece of server log you attached shows that you missed to specify the name of Data Adapter in the adapter.xml file, so that "DEFAULT" is taken as Data Adapter name (not "HELLOWORLD").
In a case like this when a LSTableInfo instance is created the dataAdapter property must not be valued so that if it is nil, the "DEFAULT" name is used.
"HELLOWORLD" is the name of the adapter set and you set it in the adapter property of LSConnectionInfo.

Please refer to the adapter.xml file in /adapters/Demo folder of Lightstreamer distribution for a more complete example of Adapter Set deploy.

Hope that help.
