hello all,
i've have again a problem with storing a byte[] in a blob under oracle ...
is there a way to store byte[]like this ( or another way any help is great ) ?
byte[] bytedata = null; and then storing it with SqlStatement = INSERT INTO BLOB_TABLE (FILENAME,FILESIZE,BLOBDATA) VALUES (?,?,?); insertstatement.setString(1,filename); insertstatement.setInt(2,filesize); insertstatement.setXXX(3,bytedata); int rows = insertstatement.executeUpdate(); insertstatement.close();
i have an example with a filestream, but no idea how to insert byte[] directly ...

hello rene,
you've been right
pdf.close() and after that pdf.get_buffer() was the error
thanks a lot
andreas spiessl

hello beksy,
i am using ie 4/5 and acrobat 5.
the insert doesn't work correctly,
(maybe the pdflib get_buffer function has an error)
i don't know where my error is ...
i would be nice if i can have a look at your code for insert and displying pdf files

hello rene, hello all
i have tried it with the code and no pdf file is displayed.
i have test my loading servlet with the database an i function, so now i think the error must be in
public final static int writeBytetoBlob( byte [] bytedata, String contenttype, String filename) { try { Connection connection = DataSourceConnection.getConnection(""); connection.setAutoCommit(false); Blob blob = null; Statement statement = connection.createStatement(); OracleResultSet resultset = null; OutputStream outputstream = null; statement.executeUpdate( "INSERT INTO MEDIA values ('1','test.pdf','application/pdf','test.pdf',empty_blob()) "); (OracleResultSet) statement.executeQuery( "SELECT DATA FROM MEDIA WHERE ID='1' FOR UPDATE"); resultset.next(); BLOB blobdata = resultset.getBLOB("DATA"); outputstream = blobdata.getBinaryOutputStream(); outputstream.write(bytedata); outputstream.flush(); outputstream.close(); connection.commit(); connection.setAutoCommit(true); connection.close(); } catch (Exception e) { log4jcategory.error("sqlqueryhelper::writebytetoblob:"+e.toString()); } return 0; }
has anybody an idea

hello all,
i have a big problem with writing a bytearray to an oracle db and display it via a servlet
i have a function to generate a pdf with the pdflib
byte[] bytebuffer=null; try { pdflib pdf = new pdflib(); pdf.open_file("tt.pdf"); pdf.begin_page(842,595); PDFlibHelper.PDF_set_information(pdf); PDFlibHelper.PDF_draw_pageheader(pdf,"",""); pdf.end_page(); pdf.close(); bytebuffer = pdf.get_buffer(); } catch (Exception e) { e.printStackTrace(); }
then i want to store the bytebuffer = pdf.get_buffer(); into an oracle database with this script:
public final static int writeBytetoBlob( byte [] bytedata, String contenttype, String filename) { try { Connection connection = DataSourceConnection.getConnection(""); connection.setAutoCommit(false); Blob blob = null; Statement statement = connection.createStatement(); OracleResultSet resultset = null; OutputStream outputstream = null; statement.executeUpdate( "INSERT INTO MEDIA values ('1','test.pdf','application/pdf','test.pdf',empty_blob()) "); (OracleResultSet) statement.executeQuery( "SELECT DATA FROM MEDIA WHERE ID='1' FOR UPDATE"); resultset.next(); BLOB blobdata = resultset.getBLOB("DATA"); outputstream = blobdata.getBinaryOutputStream(); outputstream.write(bytedata); outputstream.flush(); outputstream.close(); connection.commit(); connection.setAutoCommit(true); connection.close(); } catch (Exception e) { log4jcategory.error("sqlqueryhelper::writebytetoblob:"+e.toString()); } return 0; }
when i then try to display the result with this servlet then i get no pdf file displayed
public void performTask( javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) throws javax.servlet.ServletException, IOException { InputStream in = null; Blob blob = null; java.sql.Connection connection = null; try { connection = DataSourceConnection.getConnection(); Statement stmt = connection.createStatement(); ResultSet rs = stmt.executeQuery("SELECT DATA,CONTENTTYPE FROM MEDIA WHERE ID=1"); if (rs.next()) { blob = rs.getBlob(1); in = blob.getBinaryStream(); response.setContentType(rs.getString(2)); } OutputStream out = response.getOutputStream(); int bufferSize = ((oracle.sql.BLOB) blob).getBufferSize(); byte[] b = new byte[bufferSize]; int count = in.read(b, 0, (int) bufferSize); int pos = 0; while (count != -1) { out.write(b, 0, count); pos += count; count = in.read(b, 0, (int) bufferSize); } out.close(); out.flush(); connection.close(); } catch (Exception e) { } finally { in.close(); } }
