RE: tag doesn't recognize Struts dataBean property's
value
Yes Geeta. I do need trim() and that makes it work. That is so strange
even though when I printed out "ShopOrderExist" to confirm it has no
trailing blanks. Thanks.

Jumping in here.. yes, I think you need to trim() before you check. Also,
if that too doesn't work, can you check for something "positive" (like if
"ShopOrderExist" is equals to "false" rather than "ShopOrderExist" is not
equals to "not exists"..?).
Another thought, try to get this to work just using oridinary jsp tags and
java code (<% java code here %>) and see oif things work. Than you can
narrow the problem down to tag issues..
Good luck!
