Document

Creates a FileInputStream by using the file descriptor fdObj, which represents an existing connection to an actual file in the file system.

Usage

From source file:CachedRS.java

public static void main(String[] args) throws Exception {
    FileInputStream fis = new FileInputStream(CRS_FILE_LOC);
    ObjectInputStream in = new ObjectInputStream(fis);
    CachedRowSet crs = (CachedRowSet) in.readObject();
    fis.close();/*from   www  . j  a  va  2  s .c o  m*/
    in.close();

    Class.forName("oracle.jdbc.driver.OracleDriver");
    crs.setUrl("jdbc:oracle:thin:@localhost:1521:ORCL");
    crs.setUsername("yourName");
    crs.setPassword("mypwd");
    String sql = "SELECT SSN, Name, Salary, Hiredate FROM Employees WHERE SSN=?";
    crs.setCommand(sql);
    crs.setInt(1, 111111111);
    crs.execute();

    FileOutputStream fos = new FileOutputStream(CRS_FILE_LOC);
    ObjectOutputStream out = new ObjectOutputStream(fos);
    out.writeObject(crs);
    out.close();
    crs.close();

    fis = new FileInputStream(CRS_FILE_LOC);
