how to access database in applet

HI... I'm having an applet where we should display the database values in the applet... It works fine in the local system(same network)... but when its in the server, we r getting null values in the local system.. I created a policy file and also added that url in java.security but came error below... java.sql.SQLException: JZ006: Caught IOException: java.net.UnknownHostException: ICEBOX55 at com.sybase.jdbc3.jdbc.ErrorMessage.raiseError(Unknown Source) at com.sybase.jdbc3.jdbc.ErrorMessage.raiseErrorCheckDead(Unknown Source) at com.sybase.jdbc3.tds.Tds.a(Unknown Source) at com.sybase.jdbc3.tds.Tds.a(Unknown Source) at com.sybase.jdbc3.tds.Tds.login(Unknown Source) at com.sybase.jdbc3.jdbc.SybConnection.a(Unknown Source) at com.sybase.jdbc3.jdbc.SybConnection.handleHAFailover(Unknown Source) at com.sybase.jdbc3.jdbc.SybConnection.(Unknown Source) at com.sybase.jdbc3.jdbc.SybConnection.(Unknown Source) at com.sybase.jdbc3.jdbc.SybDriver.connect(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at QueryBuilderApplet$1.run(QueryBuilderApplet.java:221) at java.awt.event.InvocationEvent.dispatch(Unknown Source) at java.awt.EventQueue.dispatchEventImpl(Unknown Source) at java.awt.EventQueue.access$000(Unknown Source) at java.awt.EventQueue$3.run(Unknown Source) at java.awt.EventQueue$3.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)
