There are several other ways to pass values between struts actions but for your case , those wont prove good. I'll tell you anyway
1. Use OGNL expressions in your struts.xml file to pass parameter from one action to another
2. Use the hidden value strategy
3. Make user of the ValueStack to pass paramters using JSTL and OGNL between the action classes.
