java.sql.SQLException: Io exception: The Network Adapter could not establish the
connection???


plz any1 can help me???		Up0Down

 

this sort of error can happen when connection url is wrong or something wrong with your network setup

if you are doing like

jdbc:oracle:thin:@localhost:1521/xe

then do like..

jdbc:oracle:thin:@localhost:1521:xe


if it is firewall problem.you should disable it.		Image Created0Down
