Unable to upload document in oracle blob

Question

In our project it's needed to attach docs in the oracle DB, so that user can read it from the DB through aplication itself.
my project is running on Weblogic 8.1 & jdk 1.4
I am using the following code for uploading 7 downloading.
public static boolean upload(Connection cncDB, int leadID,FormFile myFile,int pageID){
          boolean flag=true;
          ResultSet rslStDB = null;
          PreparedStatement prpStDB = null;
          try{
               byte[] fileData = myFile.getFileData();
               oracle.sql.BLOB blobObj=null;
               if(pageID==1){
               prpStDB=cncDB.prepareStatement("select pitchdoc from m_deal where leadid="+leadID+" and activeflag=1 for update");
               else{
               prpStDB = cncDB.prepareStatement("select scanDocs from t_file_login_ops where leadid='" + leadID + "' for update");
               rslStDB=prpStDB.executeQuery();
               if (rslStDB.next()){
                    blobObj=(oracle.sql.BLOB)rslStDB.getBlob(1);
               OutputStream out=blobObj.getBinaryOutputStream();
               out.write(fileData);
               if(out!=null){out.close();}
     catch (NullPointerException ne) {
          flag=false;
          logger.error("NullPointerException " + ne.getMessage());
     } catch (Exception e) {
          flag=false;
          logger.error("Exception " + e.getMessage());
     } finally {
          // No need to close the connection
          DBConnectionHandler.releaseConnection(null, null, prpStDB);
     return flag;
     * @param selectedLeadID : leadID of the deal
     * @return
     public static byte[] downloadPitchDocs(String selectedLeadID,int pageID) {
     Connection cncDB = null;
     PreparedStatement prpStDB = null;
     ResultSet rslt = null;
     byte[] fileBytes = null;
     logger.info("Given ID In DAO is:" + selectedLeadID);
     try {
     cncDB = DBConnectionHandler.getConnectionDashboard();
     StringBuffer sbQuery = new StringBuffer(500);
     if(pageID==1){
     sbQuery.append("SELECT PITCHDOC from M_DEAL where leadid='" +
     selectedLeadID + "'");
     sbQuery.append(" and activeflag=1");
     prpStDB = cncDB.prepareStatement(sbQuery.toString());
     else{
          sbQuery.append("SELECT scandocs from T_FILE_LOGIN_OPS where leadid="+selectedLeadID+"");
          prpStDB = cncDB.prepareStatement(sbQuery.toString());
     logger.info("DownLoad:" + sbQuery.toString());
     rslt = prpStDB.executeQuery();
     while (rslt.next()) {
     //InboxVO inboxVO = new InboxVO();
     Blob blob = rslt.getBlob(1);
     fileBytes = blob.getBytes(1, (int) blob.length());
     } catch (NullPointerException ne) {
     logger.error("NullPointerException " + ne.getMessage());
     } catch (SQLException se) {
     logger.error("SQLException " + se.getMessage());
     } catch (Exception e) {
     logger.error("Exception " + e.getMessage());
     } finally {
     DBConnectionHandler.releaseConnection(cncDB, rslt, prpStDB);
     return fileBytes;
when i executed the application it's downloading but not uploading. don't know why.............

Dear Nishad,
Keeping objects in external content repository is not a good idea if there is a possibility that the objects can be transported to another system where they need to be used as well. The transport just copies the link to the new system. So 2 systems then are able to work with same object. When one system changes the object and saves it as the same version then other system will not be able to access it  because it still has the old keys to access the object while the keys have been changed.
Changing the model and saving it basically creates a new PHIO and deletes the old PHIO and object content key is the new PHIO id which is now present only in one system . Hence, the issue in the other system.
You can transport the record model from sandbox to production and then change the repository in sandbox system so that the sandbox system does not access the repository accessed by production system.
If the record model in its current form in sandbox is not required in production( if you need the old record model in production) then please check if there are old versions available for the record model in production system using SRMGS_DOCTOOL OR in any other system(ref: http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/b067767a-4394-2e10-1bbe-f6ab8ec7331f?QuickLink=index&overridelayout=true&51586852254984 ) . You will need to delete later versions so that the version you need is the current version of the record model( and transport to production if the production does not have old versions either).
Best Regards,
Pragya
