How to insert and retreive zip files in to blob column in oracle database?

Question

This is the code to retrieve               
while (rs.next() ) {
                    Blob fileBlobContent = rs.getBlob(1);
                    String fileName = rs.getString(2);                    
                    String value = rs.getString(3);
                    long fileNum = new Long(value).longValue();
                    java.io.InputStream is =
                         ((oracle.sql.BLOB) fileBlobContent).getBinaryStream();
                    FileOutputStream fos =
                         new FileOutputStream("c:\\temp\\"+fileName);
                    int c = -1;
                    while ((c = is.read()) != -1) {
                         fos.write(c);
This is the code to insert into the row aftre inserting empty blob
               // step 3 - now put the contents of the file
               int length = 0;
               int buff_size = 1024;
               //Writer out_clob = ((oracle.sql.CLOB)fileCobContent).getCharacterOutputStream();
               OutputStream outstream = ((oracle.sql.BLOB) fileBlobContent).getBinaryOutputStream();
               long chars_read = data.length();
               byte[] buffer = new byte[buff_size];
               while ((length+buff_size) < chars_read) {
                    outstream.write(buffer, length, buff_size);
                    length += buff_size;
                    //outstream.flush();
               // write remaining data
               int remaining = (int)(chars_read-length);
               outstream.write(buffer, length, remaining);
               // steps 4-5:
               outstream.flush();
Any help is greatly appreciated. Thanks!

String localStrFile = importFormFileArg.getFileName();
try
localStrFileExt = localStrFile                    .substring(localStrFile.indexOf(".") + 1);
     localInputStream = importFormFileArg.getInputStream();
     localBr = new BufferedReader(
     new InputStreamReader(                         localInputStream));
          /** Read line by line and count the tokens present */
     while ((localStrReadLine = localBr.readLine()) != null)
     localIntRecords++;
                    /* parse the file contents with the delimiter comma */
                    if ("xls".equalsIgnoreCase(localStrFileExt))
                         localIsMandatoryPresent = isMandatoryFieldsPresent(
                              localStrReadLine, ',');*/
                         System.out.println(localStrReadLine+" first \n\n\n ");
                         localStk = new StringTokenizer(
                              localStrReadLine, "\t");
                         StringTokenizer localStk1 = new StringTokenizer(
                              localStrReadLine, ",");
// here i am unable to getting the records pls any body helpme                                             }
