I have somme problem with largeobjects setting in a preparedstatement, here is the code with the problem in comment // :
[...] db.setAutoCommit(false); [...] LargeObjectManager lobj = pgdb.getLargeObjectAPI(); //pgdb is a PGConnection int loid = lobj.create(); System.out.println("loid : " + loid); //this give 359648 LargeObject image = lobj.open(loid); int s, count = 0; byte buf[] = new byte[2048]; while ((s = affiche.read(buf, 0, buf.length)) > 0){ //affiche is an InputStream count += s; image.write(buf, 0, s); } BlobInputStream b = new BlobInputStream(image); addDVD.setBinaryStream(4, b, count); //addDVD is an PreparedStatement //addDVD.setNull(4, java.sql.Types.BINARY); // --> all work well if I decomment this and comment the preceding image.close(); affiche.close(); [...] System.out.println("addDVD : " + addDVD.toString()); // <stream of 6503 bytes> for the fourth prm (bytea) int update = addDVD.executeUpdate(); // -->deadlocking here !!! System.out.println("update = " + update); //never pass here db.setAutoCommit(true); [...]
Am I setting the bytea in the rigth manner ? Else, how may I do that , where are my mistakes ?
