Check if site2pstoretoken is valid
Hi to all,
i'm writing my custom login page in sso environment (Oracle AS 10.1.2).
When i get from querystring parameter site2pstoretoken , i would like to check if it is valid or not (it come from sso server, but user could change it manually and then recall the login page).
When i submit page with a not valid site2pstoretoken (for example with site2pstoretoken="THISISNOTVALID") I get a 500 internal server error.
I would like to check its validity when i get it from querystring.
Is ther a method java (or another way) to check if it is valid or not? (Now i just check if it is null or not, but it is not enough).
Please help...
Thanks in advance
