You would define a base action that extends org.apache.struts.action.Action and includes a method execute() or maybe a helper method doSetup().
Your action classes would then extend this BaseAction class and then one of the first things you would do in execute() would be to call super.execute() or super.doSetup(). But, like Frank said, it would be better to decouple your logic from Struts by implementing a servlet filter which will work regardless if using struts 1.2, 1.3, 2.0, or just plain old servlets+JSPs.

Hi Frank, Referring to your response.. you might also be able to have a base Action that all your Actions extend from, and the base action does the transformation before the real work happens. This might work if you don't need the transformation to happen before that point. How does this works ? Theoretically I understand this, but how to implement this? I mean where do we mention our CustomizedBaseAction class name? some where in properties ? Can you tell me..? Anil. -----Original Message----- From: Frank W.

Do the transformation and stuff the transformed content in request as an attribute, then grab it later in your Actions. Which version of Struts are you using? If pre-1.3, modifying the RP is one of the few other options as Dave mentioned... you might also be able to have a base Action that all your Actions extend from, and the base action does the transformation before the real work happens. This might work if you don't need the transformation to happen before that point. If using 1.3.x, you could write a command to do it and modify the RP chain. If 2.x, an interceptor is probably the right answer. However, in all these cases, a servlet filter would work, and would keep your transformation logic abstracted out of Struts itself, so one less thing to worry about if you upgrade versions later :) Frank -- Frank W.
