Error while trying to Insert a pdf file in database

Hi All,

Thanks

Hi there,
I tried to insert a pdf file in to Informix database. I followed the guidelines
given in the "InformixJDBC Driver
Programmer's Guide". Actually my program works if i use
PreparedStatement.setBytes method. But why
PreparedStatement.setBinaryStream method is not working????.
Here is the code snippet.....
Connection conn = null;
PreparedStatement ps = null;
try
File ff = new File("C:\\test.pdf");
InputStream value = null;
FileInputStream fileinp = new FileInputStream(ff);
value = (InputStream) value;
int len = (int) ff.length();
System.out.println("len: " + len);
conn = connect();
String sql = "INSERT INTO dbep04m@inf10004:pg_wip_t (c_db,n_object,u_img) VALUES (\"2\",?,?)";
if (conn != null)
long stTime = System.currentTimeMillis();
ps = conn.prepareStatement(sql);
for (int ii=1;ii<=10000;ii++)
ps.setInt(1,ii);
ps.setBinaryStream(2,value,len);
int rtVal = ps.executeUpdate();
//System.out.println("return value" + rtVal);
ps.close();
conn.close();
long endTime = System.currentTimeMillis();
System.out.println("Total time taken for this run: " + (endTime-stTime)/(1000) + " seconds");
catch (FileNotFoundException ex)
ex.printStackTrace();
catch (IOException ex)
ex.printStackTrace();
catch (SQLException ex)
ex.printStackTrace();
finally
try
if (ps != null)
ps.close();
if (conn != null)
conn.close();
catch (SQLException ex)
ex.printStackTrace();
I am getting the following error message.......

Here is the example given in the "Informix JDBC Driver Programmer's Guide". In the line maked bold, the blob size was hard coded as 10. Then
why you are trying to find the file length???.
try
stmt = conn.createStatement();
stmt.executeUpdate("create table tab1(col1 byte)");
catch ( SQLException e)
System.out.println("Failed to create table ..." + e.getMessage());
System.out.println("Trying to insert data using Prepare Statement ...");
try
pstmt = conn.prepareStatement("insert into tab1 values (?)");
catch (SQLException e)
System.out.println("Failed to Insert into tab:" + e.toString());
File file = new File("data.dat");
int fileLength = (int) file.length();
InputStream value = null;
FileInputStream fileinp = null;
int row = 0;
String str = null;
int rc = 0;
ResultSet rs = null;
System.out.println("Inserting data ...\n");
try
fileinp = new FileInputStream(file);
value = (InputStream)fileinp;
catch (Exception e) {}
try
pstmt.setBinaryStream(1,value,10); //set 1st column
catch (SQLException e)
System.out.println("Unable to set parameter");
set_execute();
public static void set_execute()
try
pstmt.executeUpdate();
catch (SQLException e)
System.out.println("Failed to Insert into tab:" + e.toString());
e.printStackTrace();
Best Regards

Answer 1

sorry!!!. There is an error in the code
old code :
value = (InputStream) value ;
should be code :
value = (InputStream) fileinp;
