How to call statement's execute function to execute procedure in Oracle?

Question

I made a very simple procedure in oracle logged as internal user.
the procedure as the following:
create or replace procedure temptest
as
begin
insert into indextab(idx) values(100);
commit;
end temptest;
in Java program,I use Oracle's jdbc driver to connect database, still connect as internal user.
I can call statement.executeUpdate("insert into indextab(idx) values(100)"). and 100 row was added in database.
then,I delete this row, try to run procedure in java,
but the call of statement.execute("temptest") throw a exception
the error message is:"java.sql.SQLException: ORA-00900: invalid SQL statement"
then, I write the same procedure in sql server.
all things work right.( I use jdbc-odbc bridge connect to sql server database)
who can tell me what's the reason?
I'm so urgent, please help me as soon as fast, thank you very much

Answer 1

Instead of a Statement object, use a CallableStatement. CallableStatement is the JDBC wrapper for a stored proc. JDBC requires that the vendor specific call be wrapped in a {CALL ....}.
So, your code would look like the following:
Connection con = some connection;
CallableStatement cs = con.prepareCall("{CALL temptest}");
cs.execute();
Take a look at the Javadoc. You can set both IN and OUT parameters using a CallableStatement.
