Why DBMS_LOB.CONVERTTOBLOB gives me exception?

Hi, guys:
I have a task to implement a download link in apex to download RTF file. I have finished the APEX part, however, I got the problem in the PL/SQl part. Here is my code:
      procedure downloadTest is
                strLetter clob;
                strLetter_len number;
                v_mime varchar2(48) := 'application/msword';
                v_blob      BLOB;
                v_blob_offset integer;
                v_clob_offset integer;
                v_blob_csid integer:=DBMS_LOB.DEFAULT_CSID;
                v_lang_context integer:=DBMS_LOB.DEFAULT_LANG_CTX;
                v_warning integer;
                l_server sor_email_config.server%type;
                l_sender sor_email_config.sender%type;
                error_message varchar2(500);
      begin
              strLetter:='Test if this file downloadable!';
              --strLetter_len:=DBMS_LOB.GETLENGTH(strLetter);
              strLetter_len:=DBMS_LOB.LOBMAXSIZE;
              v_blob_offset:=1;
              v_clob_offset:=1;
              v_blob:=null;
              DBMS_LOB.CONVERTTOBLOB(v_blob, strLetter, strLetter_len, v_blob_offset, v_clob_offset, v_blob_csid, v_lang_context, v_warning);
              OWA_UTIL.mime_header (NVL (v_mime, 'application/pdf'), FALSE);
               HTP.p ('Content-length: ' || strLetter_len);
               OWA_UTIL.http_header_close;
               WPG_DOCLOAD.download_file (v_blob);
      exception
          WHEN OTHERS THEN
                  error_message:=substr(SQLERRM, 1, 400);
                  raise_application_error(SOR_ERROR_CONSTANTS_PKG.errnum_GENERAL, 'SOR_COMPLIANCE_ADMIN.downloadTest when generating document '||SOR_ERROR_CONSTANTS_PKG.errmsg_GENERAL||error_message);
      end downloadTest;however, I got exception as follows:
ORA-06502: PL/SQL: numeric or value error: invalid LOB locator specified: ORA-22275 for Execute PL/SQL Code.
I know the problem occurs during DBMS_LOB.CONVERTTOBLOB. Could anyone give me a hint about this problem?
Thanks a lot!

Thank you for all help you guys provided! I finally made it. It looks APEX 4.1/11GR2 conflicts with wpg_docload.download_file, I have to raise APEX internal exception by calling apex_application.stop_apex_engine, and call the download process in a application process. check Blob download via wpg_docload is not working
for anyone's convenience:
      procedure downloadTest is

If image file not exist in image path crystal report not open and give me exception error problem

Hi guys my code below show pictures for all employees
code is working but i have proplem
if image not exist in path
crystal report not open and give me exception error image file not exist in path
although the employee no found in database but if image not exist in path when loop crystal report will not open
how to ignore image files not exist in path and open report this is actually what i need
my code below as following
DataTable dt = new DataTable();
string connString = "data source=192.168.1.105; initial catalog=hrdata;uid=sa; password=1234";
using (SqlConnection con = new SqlConnection(connString))
con.Open();
SqlCommand cmd = new SqlCommand("ViewEmployeeNoRall", con);
cmd.CommandType = CommandType.StoredProcedure;
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd;
da.Fill(dt);
foreach (DataRow dr in dt.Rows)
FileStream fs = null;
fs = new FileStream("\\\\192.168.1.105\\Personal Pictures\\" + dr[0] + ".jpg", FileMode.Open);
BinaryReader br = new BinaryReader(fs);
byte[] imgbyte = new byte[fs.Length + 1];
imgbyte = br.ReadBytes(Convert.ToInt32((fs.Length)));
dr["Image"] = imgbyte;
fs.Dispose();
ReportDocument objRpt = new Reports.CrystalReportData2();
objRpt.SetDataSource(dt);
crystalReportViewer1.ReportSource = objRpt;
crystalReportViewer1.Refresh();
and exception error as below

First: I created a New Column ("Image") in a datatable of the dataset and change the DataType to System.Byte()
Second : Drag And drop this image Filed Where I want.
private void LoadReport()
frmCheckWeigher rpt = new frmCheckWeigher();
CryRe_DailyBatch report = new CryRe_DailyBatch();
DataSet1TableAdapters.DataTable_DailyBatch1TableAdapter ta = new CheckWeigherReportViewer.DataSet1TableAdapters.DataTable_DailyBatch1TableAdapter();

DataTable dt = GetImageRow(table, "Footer.Jpg");
report.SetDataSource(dt);
crv1.ReportSource = report;

When creating a table why should we give promary key

when creating a table why should we give promary key

Hi Rambabu,
Primary key is needed so as to avoid duplicate entries and ensure that there are unique entries in the table.
For some applications, it is useful to uniquely identify the rows in a table by one or more columns so that you can process them in a specified sequence, for example. You can do this by assigning a primary key. The column names that are to create the table key are represented by the keywords PRIMARY KEY. The input values of the key columns defined in this way must not be a NULL value.
You can use the primary key to insert rows in a table in the same way as you insert rows in a base table when no primary key is defined. However, the system outputs an error message if you attempt to insert an existing value into the primary key column a second time, since the uniqueness of the column is ensured by defining the primary key.
A primary key can consist of multiple columns. However, it is unusual for a key to be constructed from more than five columns, since this makes it difficult for users to enter unique values. The arrangement of the columns behind the keywords PRIMARY KEY defines the key sequence.

Sekhar

Why we should give currency type 30 in 2nd local currency ?

Hi,
why we should give currency type 30 2nd local currency in Define Currencies of Leading Ledger. Here 30 indicates EUR only. I want to give USD as 2nd local currency.
Please suggest.
Thanks,
Gangaraju

Group currency is unique at client level, i.e. this is same for all company codes.
go to scc4
Check the currency of your client.
This currency comes by default for group currency and you can't give as your own.
If you have any requirement, then you can give it as third local currency.
Also remember third local currency you have to maintain at first country level.

Why the system gives 1st priority to doc type for shipping con value

Hi gurus
I want to know one thing,
When we create a sales order the system take the shipping condition value from the doc type first,if it does not get any value then only it serch customer master for the value.
I just want to know that why the system gives first priority to doc type shipping con value?
What is the reason behind it?
it was asked me in an interview
Please give me the ans.
Thanks And Regards
Babi
Edited by: babisap on Mar 30, 2010 7:26 AM

Hi Babi,
Mostly SAP systems are built in such a way that it gives you control for same functionality at various levles.In your case if you configure the shipping conditions at the document type then (irrespective of what shipping conditions are maintainned at customer master)they are defaulted .This is required to default shipping conditions for some perticular business scenarios like all rush orders to be shipped from express shipping point.
But if yoiu do not want the more generic control then the same can be at customer master level.

On top of that, of the 143 questions, 112 of them are still showing as unresolved, indicating that they are either not asking questions in a way that people can answer them, or that they are not marking their questions as answered when they receive an answer. There's a thing called Forum Etiquette, and this member is clearly showing that they are not following it.
Also, sb92075 is not preventing anyone else from providing valuable suggestions or stopping anyone from learning. If anything, asking questions to which the answers can be found easily on the internet ( http://lmgtfy.com/?q=where+1%3D1 ) could very easily be seen as an abuse and waste of the volunteers time, and detracting from other members with valid issues to be resolved.

When adjusting the audio volume in a selected region, why does it give me a curved line instead of straight and why cant I change it like i can with a fade in our out?

When adjusting the audio volume in a selected region, why does it give me a curved line as a transition instead of straight, and why cant I change the fade shape like i can with a fade in our out? When I slide thet volume all the way down it makes a very abrupt down curve. It's audibly noticdible.
Thank you.

Use the range selection tool and select the portion of the clip you want to change the volume on. Drag the volume line down and FCP will create keyframes which you can adjust as you want to get a fade shape.

I have a local LAN DNS server. My preferences point to that server. Why does dig give me 8.8.8.8 as my DNS server?

I have a local LAN DNS server. My preferences point to that server. Why does dig give me 8.8.8.8 as my DNS server?
Something is/was modifying my DNS preferences to 8.8.8.8 It seems to be pointed correctly now (at my local LAN DNS server), but why was it pointed at 8.8.8.8 before? I never want it pointed to 8.8.8.8

You've hit the nail on the head Ben. For point to point communications, the IP addresses should be fixed, therefore there is no need for DNS. If a DNS is configured, the NIC (Network Interface Card) drivers will try to contact it.
In my test system, I need DNS for the test computer, but I am communicating with a dedicated Spectrum Analyzer over TCP/IP. So I added a second NIC. The main NIC is configured for DNS and all that jazz. The second NIC (plugged into PCI slot) is configured with a hard coded address, no DNS, no Gateway, nothing else. I connect that NIC to the spectrum analyzer using a crossover cable. The analyzer is configured with a hard coded address also. Now my computer can get on our company network, and the spectrum analyzer is isolated from the network, so it can't catch any viruses, etc., and it still talks to the computer. When using a configuration such as this, it is best to use a dedicated address for the 2nd NIC and spectrum analyzer in the range of 192.168.100.0 to 254
