execute a function (ref cursor) in a jsp using jdbc and show the resultset

I am having a database function which its name is get_budget(year_v, usr_v) and accepting two parameters the year and the usr. Now, I am trying to execute this by using the jdbc.

In toad when I am trying to execute using a select statement : select get_budget(2010, maa_maa) from dual, it is diaplaying a cursor. But how do that in the jdbc,开发者_开发技巧 so I can retrieve the data directly and print them.

I guess it is about the same as in dynamic sql, describe the cursor, find the columns and datatypes and print the accordingly. See for example Selecting the ref_cursor from JDBC
