PROCEDURE PRC_GET_DATA( VAR_ONE IN VARCHAR2, IO_CURSOR OUT data_cursor ) ;
END ;
PACKAGE BODY PKG_TEST IS
PROCEDURE PRC_GET_DATA( VAR_ONE IN VARCHAR2, IO_CURSOR     OUT data_cursor ) IS
MENSAJE VARCHAR2(1000);
CURSOR_AUX DATA_CURSOR;
ERR_NUM NUMBER;
ERR_MSG VARCHAR2(100);
BEGIN
     OPEN CURSOR_AUX FOR
     SELECT ATTRIB1, ATRIB2 FROM TABLE WHERE (CODITION);
IO_CURSOR := CURSOR_AUX;
END PRC_GET_DATA;
END;
and, i have some troubles to call from JSP page...
the java Source is
Connection conn = source.getConnection();
Statment stmt = conn.createStatment();
CallableStatment cs = conn.prepareCall( {CALL PKG_TEST.PRC_GET_DATA( '%') } );
ResultSet rset = cs.executeQuery();
Some can help me?....

I would not know about JAVA call Syntax to Oracle procedure in the code you are showing, Also it is not
the right place for that question. How ever, I can see that your PL/SQL code needs some fixing
before it can compile and run, hence some simple demonstrationSQL> create or replace package test_pkg as
  2  TYPE data_cursor IS REF CURSOR;
  3  PROCEDURE PRC_GET_DATA( VAR_ONE IN VARCHAR2, IO_CURSOR OUT data_cursor);
  4  END;
  5  /
Package created.
-- Please note that you need to put your SQL for ref cursors in single quotes
-- Also look at the passing the WHERE condition to the SQL
SQL> create or replace package body test_pkg as
  2  PROCEDURE PRC_GET_DATA(VAR_ONE IN VARCHAR2, IO_CURSOR OUT data_cursor) IS
  3    l_cursor data_cursor;
  4  BEGIN
  5    OPEN l_cursor for ('SELECT empno, ename from my_emp WHERE '|| VAR_ONE);
  6    IO_CURSOR := l_cursor;
  7  END;
  8  END;
  9  /
Package body created.
-- Then simply use the returned REF CURSOR in any program, I am showing PL/SQL program here
SQL> Declare
  2     myCur test_pkg.data_cursor;
  3     vEmpNum Number;
  4     vEname  Varchar2(20);
  5  Begin
  6     test_pkg.PRC_GET_DATA('Sal > 1000', myCur);
  7     Loop
  8       Fetch myCur into vEmpNum, vEname;
  9       Exit When myCur%NOTFOUND;
10       dbms_output.put_line(vEmpNum || '  ' || vEname);
11     End Loop;
12     Close myCur;
13  End;

PL/SQL procedure successfully completed.Might not be exactly what you are looking for, but from Oracle Forum, this is what is relevant.
Good luck,
