Accessing Applinx Fields from previous jsp pages

How can I access field data from previous jsp pages in Applinx/Java within the same Session? I am not a java wiz, so I would appreciate any assistance in how to structure a call to retrieve a field value from previous jsp pages. Does Applinx have the equivalent of Global data available anytime in the current Session? This relates to my previous entry on Applinx.

Please discuss ApplinX topics in the Application Modernization forum to
get a chance that they will be answered,
