We use Struts 1.3.8.

We use velocity to render the output for each individual operation.  In 
the operationsV7.xml file there is an attribute on the operation element 
called output_template.  When the product is finished, the Struts 
servlet passes control to the 
gov.noaa.pmel.tmap.las.view.LASVelocityViewServlet.  This renders the 
output into the correct form using the template defined in the 
output_template attribute and passes it back to the requesting client.  
In the UI most of the actual display logic is JavaScript populated with 
data retrieved via Ajax calls, but the lower right pane that display the 
plots is the place where the output from the Velocity template is 
typically rendered.

We've been having some discussion about what it is you might be trying 
to accomplish.  If you want to add a regression fit line to a particular 
product display for particular data sets, your best bet might be to 
modify the existing script to calculate the fit and display the line 
based on the value of a property.  Then you could control whether it 
appeared for a particular variable by adding a property to the variable 
definition in las.xml.

This would be easier than creating an entirely new operation.
