Hi, experts
My backing bean needs to connect to database through connection
pool/DataSource on tomcat (v5.5.16). Now I changed my backing beans
from session to request scope trying to use t:savestate tag, then I made
them serializable, but it started giving exceptions
[NotSerializableException for
PoolingDataSource$PoolGuardConnectionWrapper}. So, Are there any other
options or work around or am I doing something wrong ?
Thanks for your help,
yasushi
