The code you listed is the DE API for getting design values not runtime
values. Can you give some more details one what you are trying to do?
Is this app web based, client/server?

Are you using a data set parameter for the nested table?
Take a look at this example video:

If you create a data set parameter on the nested table and set it in the
binding like the video showed, you can access its value in Java in the
beforeOpen like:
dataSet.getInputParameters().get("param_1");

You can not get it from the reportContext object. You have to use the
dataSet object.
public void beforeOpen(IDataSetInstance dataSet,
IReportContext reportContext) throws ScriptException {
Object val = dataSet.getInputParameters().get("param_1");
