pg_dump from Java or SQL?

Is it possible to access backup and restore functionality from SQL or Java?
I am attempting to allow some this functionality from a webapp.

The best I have so far is the following Java code.

Runtime runtime = Runtime.getRuntime();

String[] cmd = { "cmd",

"/c",

"C:/PostgreSQL/8.0/pgAdmin_III/pg_dump.exe -i
-h localhost -p 5432 -U postgres -F c -b -v -f C:/"

+(new Date()).getTime()

+".backup mydatabase" };

Process p = runtime.exec(cmd);

Thank you for your time,
