First of all, I don't quite get what you mean by tabular data.Please explain in detail.

Anyway, if you want to send huge amount of data from the jsp to an ejb via servlet what you can do is write a data-object class where you declare a certain number of instance fields and define getter and setter methods for those fields. Now in the JSP, set the values of those fields in hidden variables. In the servlet, extract the values of those fields using request.getParameter("param-name"). Create an object of the data-object class that you had written earlier and use the setter methods in that class to set the values of the parameters that you have extracted in the servlet.Now pass this object to the ejb (session bean) method. In the ejb, you can get the values of the fields using getter methods of the data-access object.

By tabular data if you mean, that the same form field can contain multiple values, then in the servlet use request.getParameterValues("param-name").

yes u create a class that implements serializable interface. make public attributes equals to fields u want and set values in attributes this make a complete row and pass it to jsp/servlet/bean methods.if u want to send multiple rows then create a ArraList and add objects of ur class in it and receive as Collection. :-)
