Hi Yatish,

In Java you can call this way,

ParameterPage newParamsPage = new ParameterPage();

newParamsPage.putString("EmployeeName", "Mahesh"); -> This is the parameter which my GetEmployeeData activity will take as input

HashStringMap params = new HashStringMap();
params.putString("pxObjClass", "Rule-Obj-Activity");
params.putString("pyClassName", "Mahesh-Case1");
params.putString("pyActivityName", "GetEmployeeData");
tools.doActivity(params, null, newParamsPage);

Hope this is clear to you.

Regards

Mahesh
