GetMimeType()

Hi Everyone!,
I want to upload any random file into my table in form of BLOB and simultaneously want to fill the respective another column with its MimeType. Earlier I used Oracle Apex for this, but due to my new requirement I need to make this happen with the help of PL SQL and/or Forms. Could you add some input in this? If you could put example also then it would be awesome.
Thanks
Harbinder

There are (Java) procedures that check the mime type, but they almost all rely on known file extension names. It is practically impossible to check the contents of a file to see what the mime type is. I use this procedure:
function get_mime_type(i_filename in varchar2)
return varchar2
is
   cursor c_mte(b_ext in varchar2) is
      select mime_type
      from   a_mime_types
      where file_extension = lower(b_ext);
   v_file_extension    a_mime_types.file_extension%type;
   v_mime_type         a_mime_types.mime_type%type;
begin
   v_file_extension := substr(i_filename,instr(i_filename,'.',-1));
   open c_mte (v_file_extension);
   fetch c_mte into v_mime_type;
   close c_mte;
   return v_mime_type;
end get_mime_type;where the table is defined like this:
a_mime_types
mte_id          number(10)                    not null,
file_extension varchar2(10 byte)             not null,
mime_type       varchar2(100 byte)            not null
) [here|http://www.feedforall.com/mime-types.htm] So, when you upload a file, call this function too.
Oh, I got my mime types list here .

It's the name file (or with the relative path ) of the file that reside on the context path of the web aplication (in the servlet container where it is deployed).

FacesContext ,getMimeType,setContentType

I need to know the mimetype of a know file to doanload it, how can I do this?
I need this response.setContentType(file.type);
Edited by: dimis on Dec 10, 2009 2:00 AM

If you're using JSF 2.0, then you can call ExternalContext.getMimeType().
If you're using a version of JSF prior to 1.2, then you'll need to call ExternalContext.getContext() and downcast to ServletContext and call getMimeType() from there.

OrdDoc.getMimeType() null

The following doc is loaded successfully and later added to the database successfully, but for some reason the mime type is always null. Any ideas?
OrdDoc doc = (OrdDoc) rset.getORAData(1, OrdDoc.getORADataFactory());
doc.loadDataFromFile(path + mf.getRef());
System.out.println(doc.getMimeType()); // null

Hi Mavris
Thanks for the reply.
In my example the reason i did not invoke setProperties() method is because the setProperties method exposed in OrdDoc class is not same as the setProperties method in OrdAudio or OrdImage.
In OrdDoc class setProperties(byte[][] ctx,boolean setComments) takes two arguments where as setProperties() in OrdAudio and OrdImage does not take any arguments.
byte[ ] ctx[ ] = new byte [4000][1];
When i tried to use setProperties(ctx,true) in OrdDoc i was getting an error.
Can you please tell if this is the correct way to invoke setProperties on OrdDoc in Java Program?
Regarding the list of format that Intermedia Understands, the Appendices A, B and C in Intermedia Refererence talks only about Audio, Image and Video. It doesnt have any details about Document (pdf, txt, doc) files. Can you please tell where can i look for the list of formats that intermedia understands for OrdDoc?
Since the dataType is OrdDoc in my table. How do i check the LOB length?
I tried it using Intermedia Java API by calling getContentLength method after retreiving the OrdDoc column from resultset but it has a value of '0'. So am not sure why the document is not getting loaded.
Please help me resolve this issue.
Thanks

DOC.getMimeType() is null

Hello Gurus,
Getting DOC.getMimeType() as null when using ORADOC after Import , Unable to find the document type.
Importing is done through a URL using ordsys.orddoc.import(), the filename is an ID, we call the document using that ID, will not know the filetype until Opened.
Any Suggestions.
Thank you

Sorry Its ORDDOC not ORADOC

Hi Sambo44,
Thanks for your posting!
I am not totally understanding your meaning. How did you get this error?Did you want to login on Azure form your VS? From your error message, I am not sure you can login on Azure portal using your account. Please make sure your account is right.
Or did you try to use ACS or WIF in your project for authorization? If it is , I suggest you can post this issue on Azure AD forum for more details.
Any question about this issue, please feel free to let me know.

Well Well Well..
That would not work...
What you have to do is save the uploaded file content on to a location and then pass the fileName as a request parameter to a deidicated which displays the contents of that file.
Just as an example
<html>
<head>
<title>File Upload Display</title>
</head>
<body>
<%
//ServletOutputStream sout=response.getOutputStream();
StringBuilder strBuilder = new StringBuilder();
int count=0;
String f;
f=request.getParameter("filedb");
DBManager dbm = new DBManager();
//dbm.createTable("mms3");
//log.info("In JSP : "+ f);
//dbm.insert_data(f,"mms3");
%>
<%
if (ServletFileUpload.isMultipartContent(request)){
ServletFileUpload servletFileUpload = new ServletFileUpload(new DiskFileItemFactory());
List fileItemsList = servletFileUpload.parseRequest(request);
strBuilder.append("<?xml version=\"1.0\" encoding=\"UTF-8\" ?>").append('\r').append('\n').append("<xpage version=\"1.0\">").append('\r').append('\n');
String optionalFileName = "";
FileItem fileItem = null;
Iterator it = fileItemsList.iterator();
ServletOutputStream outputStream=null;
while (it.hasNext()){
 FileItem fileItemTemp = (FileItem)it.next();
%>
Name-value Pair Info:
Field name: <%= fileItemTemp.getFieldName() %> 
Field value: <%= fileItemTemp.getString() %> 
<%
if (fileItemTemp.getFieldName().equals("filename"))
 optionalFileName = fileItemTemp.getString();
if(!fileTempItem.isFormFiled()){
 String fileName = fileItem.getName();
 fileItem.write(optionalFileName);
%>
Uploaded File Info:
Content type: <%= fileItem.getContentType() %> 
Field name: <%= fileItem.getFieldName() %> 
File name: <%= fileName %> 
<%
if(fileItem.getContentType().equals("image/jpeg") || fileItem.getContentType().equals("image/pjeg")) {
%>
<img src="FileServlet?fileName=<%=optionalFileName%>"
<%
%>
</body>
</html>a sample code snippet for FileServlet.
String fileName = request.getParameter(fileName);
File file = new File(fileName);
 if(!file.exists())
 return;
// If JSP
String mimeType = application.getMimeType("fileName");
 If you are using servlet
 String mimeType = this.getServletContext().getMimeType(fileName);
 response.setContentType(mimeType);
 response.setHeader("Content-Disposition","inline;filename=\\"+fileName+"\\");
BufferedOutputStream out1 = null;
InputStream in = null;
if(mimeType == null)
 mimeType = "application/octet-stream";
try{
 in = new FileInputStream(f);
 response.setContentLength(in.available());
 BufferedOutputStream out1 = new BufferedOutputStream(response.getOutputStream(),1024);
 int size = 0;
 byte[] b = new byte[1024];
 while ((size = in.read(b, 0, 1024)) > 0)
 out1.write(b, 0, size);
}catch(Exception exp){
}finally{
 if(out1 != null){
 try{
 out1.flush();
 out1.close();
 }catch(Exception e){}
 if(in != null){
 try{in.close();}catch(Exception e){}
} Hope that might answer your question :)
However,this is not the recommended way of doing this make use of MVC pattern.Would be a better approach.
you might think of googling on this and can findout what is the best practise followed for problems of this sort

ý am sending data from remote as a string and want to write it in xml. But it is not working. Where am i wrong?

I fixed it. But now it doesnt write to file and there is no error. So i cant find where am a wrong.
I send a request, it is taking string but it is not writing to file eventhough it is entering the try block.
Why it isnt writing? Is not servlet let it to write to file. My working code is here

What if i want to print content from any file.
So anybody konwing this plz reply

This is covered pretty well in the Java Print Service API Guide.
You could start here http://java.sun.com/j2se/1.4.1/docs/guide/jps/spec/printing.fm1.html
Basically, you have two choices - either you're going to throw a document at the print service, or you're going to print using Graphics2D commands. You also have the choice between printing to a printer, or to a stream. Mix and match for four combinations.
Whether you can just take a raw document and send it to a printer via the document printing stuff depends on what print services you have installed. For the standard J2SE, it's pretty limited.
If you're doing it via the Graphics2D approach, however, you can print anything you can draw. That's nice - it means you can use the same code to display stuff on the screen and print it.

Link Item Style to open a PDF hangs if opened in IE in 30 seconds

Hi,
I am using Jdeveloper version 9.0.3.
I have a page in which, I have an advanced table, in which there is a column, with item style - link.
On the link item there is a PPR event and it should open a PDF file, residing on the server.
I am using java code to open the PDF file.
In Internet Explorer, the link doesnt work, infact the Explorer hangs and the user has to exit the window.
This doesnt happen in Firefox. However, this is critical as , use of firefox is not allowed, and the users have to ultimately use IE.
Below is the java code for opening the PDF file from the server:
public void downloadFileFromServer(OAPageContext pageContext, String file_name_with_path, String file_name_with_ext)
HttpServletResponse response = (HttpServletResponse) pageContext.getRenderingContext().getServletResponse();
if (file_name_with_path == null || "".equals(file_name_with_path)){
throw new OAException("File path is invalid.");
File fileToDownload = null;
try{
fileToDownload = new File(file_name_with_path);
}catch (Exception e){
throw new OAException("Invalid File Path or file does not exist.");
if (!fileToDownload.exists()){
throw new OAException("File does not exist.");
if (!fileToDownload.canRead()){
throw new OAException("Not Able to read the file.");
String fileType = getMimeType(file_name_with_ext);
response.setContentType(fileType);
response.setContentLength((int)fileToDownload.length());
response.setHeader("Content-Disposition", "attachment; filename=\"" + file_name_with_ext + "\"");
InputStream in = null;
ServletOutputStream outs = null;
try{

Hi Kristofer,
We did look at the possibility for using messageDownload bean instead of a link, but we do not want to store the file as a LOB.
The file needs to be stored in the server location.
Any clue as to why the file opened in the browser ( on clicking on the link) hangs and this is happening only in IE.
Thanks,
AJ

Need help with my HttpConnection From Midlet To Servlet...

NEED HELP ASAP PLEASE....
This class is supposed to download a file from the servlet...
the filename is given by the midlet... and the servlet will return the file in bytes...
everything is ok in emulator...
but in nokia n70... error occurs...
Http Version Mismatch shows up... when the pout.flush(); is called.. but when removed... java.io.IOException: -36 occurs...

1) Have you looked up the symbian error -36 on new-lc?
2) Have you tried the example in the response on forum nokia?
3) Is the address "121.97.220.162:8084" accessible from the internet, on the device, on the specified port?

Still have the same error messages

Hi Rajiv,
Thanks a lot for your help. I tried to load the java package
before I exported my images. The loading java worked sucessfully,
however the same error messages came out when I exported images.
Actually, I stored five JPEG images as ORDSYS.ORDImage in a table
for a test. Below is my image-loading codes and the images are
truely in the database since I proved it by running a
check-properties script.
-- This program will create a table called imgtable and import
-- five .jpg files into it. Also the status of the images will
-- be checked.
connect imgdemo/imgdemo;
set serveroutput on
set echo on
-- decomment for demo images
drop table imgtable;
create table imgtable (id number,
Image ORDSYS.ORDImage);

insert into imgtable values(1,ORDSYS.ORDImage.init());
-- Insert a row with empty BLOB.
insert into imgtable values(2,ORDSYS.ORDImage.init());

insert into imgtable values(3,ORDSYS.ORDImage.init());
-- Insert a row with empty BLOB.
insert into imgtable values(4,ORDSYS.ORDImage.init());

insert into imgtable values(5,ORDSYS.ORDImage.init());

select Image into obj from imgtable where id = 1 for update;
obj.setSource('FILE','IMGDIR','1.jpg');
obj.import(ctx);
update imgtable set image = obj where id = 1;
commit;

host ls -l ~/img/test.dat;
The error message is as follows:
ERROR at line 1:
ORA-06510: PL/SQL: unhandled user-defined exception
ORA-06512: at "ORDSYS.ORDSOURCE", line 354
ORA-06510: PL/SQL: unhandled user-defined exception
ORA-06512: at line 13
I really tried everything to fix it and still doesn't work. I
guess maybe the export method is not implemented for intermedia.
Best regards,
Kai

Kai,
You're almost there! I apologize for not providing a complete
response previously. I thought the webiv note had sufficient
details on java file permissions.
For export to work, ORDSYS needs write permissions on the file
as well.
call DBMS_JAVA.GRANT_PERMISSION( 'ORDSYS',
 'java.io.FilePermission',
 '/home/oracle/img/test.dat',
 'write');The interMedia documentation doesn't correctly describe all the
requirements for granting file write access using
DBMS_JAVA.GRANT_PERMISSION. You must
either grant write access to public, or to both a specific user
and the ORDSYS user name. For example, you might grant write
access to all files in all directories to ORDSYS and write access
to all files in a specific directory to SCOTT.
call DBMS_JAVA.GRANT_PERMISSION( 'ORDSYS',
 'java.io.FilePermission',
 '<<ALL FILES>>',
 'read,write');
call DBMS_JAVA.GRANT_PERMISSION( 'SCOTT',
 'java.io.FilePermission',
 'D:\ordjava\test\data\*',
 'read,write');See the security and performance section in Oracle Java
Developer's Guide and the java.io.FilePermission class in the
Java API for more.
Hope that helps,
Rajiv

Microsoft Word "Smart Quotes"

I hope this will save other developers some time.
This may be obvious to others, but I just spent several hours Googling and testing to determine what actually happens when a user copies text containing "Smart Quotes" from Microsoft Word into a Java JTextComponent. For those not familiar with Smart Quotes, by default, MS Word changes double-quoted strings from using the US-ASCII character for quote (0x22) into left- and right- curly quotes (UTF-16: 0x201c and 0x201d). Word also does this with serveral other characters. This plays havoc with the display and Java Strings later encoded with java.beans.XMLEncoder, unless treated carefully. Here is what I discovered (obviously, this applies to MS Windows):
All values are in hexadecimal.
- Word is storing the character for double quote as UTF-16 internally (201C).
- When the character is copied to the clipboard, it is copied as UTF-8 (E2 80 9C).
- When the clipboard is pasted into Java, Java is assuming the it was originally Windows-1252 encoded, because that is the default for the US-EN locale in Windows XP (probably also Vista, but I only tested in XP).
- Java translates this into a-circumflex, euro-sign, o-e-ligature, the characters corresponding to E2, 80, and 9C respectively in Windows-1252 and represents it internally in UTF-16 as 00E2 20AC 0153.
-When the String is XML-encoded using java.beans.XMLEncoder, it is written in UTF-8 as C3A2 E282AC C593, which equates to UTF-16 00E2 20AC 0153 -- the characters a-circumflex, euro-sign, o-e-ligature.
I am not sure how to fix this, but maybe another reader does. I am experimenting with the Clipboard (java.awt.datatransfer) to see if I can programmatically find out the original character encoding (in this case, UTF-16).

Doesn't the DataFlavor contain the character encoding? What is the content of the InputStream returned by
            InputStream is = (InputStream)contents.getTransferData(DataFlavor.getTextPlainUnicodeFlavor());
If I use
                DataFlavor df = DataFlavor.getTextPlainUnicodeFlavor();
                String mimeType = df.getMimeType();
                String encoding = mimeType.replaceAll(".*?charset=(.*?)\\s*$", "$1");
                InputStream is = (InputStream) contents.getTransferData(df);
                ByteArrayOutputStream baos = new ByteArrayOutputStream();
                byte[] buffer = new byte[1024];
                for (int count = 0; (count = is.read(buffer)) != -1;)
                    baos.write(buffer, 0, count);
                baos.close();
                result = baos.toString(encoding);to transfer
Hello "World"
which Word changes the quotes to the smart 'smart quotes' version I get as a result
Hello World
which is what I expect.
Am I missing something?
