Yes, you can, though I don't really thing it's the right way to go. Basically you use the body content of the <s:set> tag to set the variable to the value of a scriplet expression like so:
<s:set value="fred"><%= myVar%></s:set> Again, there are much better ways of coding modern web applications that resorting to scriplets and I would certainly take the time to eradicate all scriplets from your code as soon as you can, you will be happy you did.
