The Web and JDBC
By default, applets are not allowed to load libraries or read and write files. In addition, applets are not allowed to open sockets to machines other than those they originated from. These restrictions cause a number of problems for those wishing to develop applets that work with databases. For example, many drivers rely on the ability to load native code libraries that actually generate the connection to the specified database. One way around these restrictions is to turn them off in the browser being used. This is acceptable for an Intranet being used within a single organization; however, it is not acceptable as a general solution.
