how can a bean access the XML data

[m-rao]

Hi,   Using Cocoon 1.8 I am calling an xml page. On the click of a button I wish to call a java bean to process the data. How will the bean access the data? In a JSP we do the same using the get-set methods. In XSP how does the bean have access to the data and how should the bean be called from the xml?   Thanks,   Raju
