Can we connect Applet to a database using JDBC without using any Web Server. My programme is working using Web Server but not without it. The error it gives is
com.ms.security.SecurityExceptionEx[AppletJdbc.init]

a jdbc connection is not permitted for untrusted applets, thus the security exception. u can make your applet trusted for achieving this. see another thread at http://www.javaranch.com/ubb/Forum23/HTML/001052.html for making your applet trusted.

Also, jdbc connections frequently use tcp/ip ports that get blocked by firewalls

"privilege" comes from the Latin words for "private" and "law" (legal) and dates to feudal times. To "claim privilege" meant that you were above the laws that applied to the common people.

It is normally difficult to connect an applet to a database 'coz applets have a high security model. However, it is possible thru the careful use of code............sometimes this throws a security exception esp when u r asking the applet to communicate with the system outside the java environment
