Rtdserver data fetching from java program

my project which is written in java requires data from the rtdserver. when the attached excel opens, it reads the data from the rtd server. I want to get the same real time data into my application. opening this excel and reading the data continuously doesn't work as the data is not saving and also excel is open it will crash the opening of the same excel from the java program. It is optimum to fetch the real time data from the rtdserver directly through the java program. Those who are experienced with the rtdserver programs can bid for this project. Attached excel gives the parameters for the RTD call from the excel.
