How to determine mime-type of a file using OSB

I was working on a requirement where in it requires to use FILE/ FTP adapters using OSB or BPEL as solution. The idea is to pick up files from one location to another location for certain legacy platforms. The real issue is, someone can put a JPEG file in the upload/download location(s), merely by changing the extensions. When this happens the systems will not process since the mime-type is incorrect.
I know of an open-source API (Apache-Tikka) to determine the mime-types, but then if we use open-source why would customer buy from us.
The intention is to pick-up the file and simply pass-it (and not parse) on to next system using File or FTP adapter, but in the process, cross check the MIME-TYPE before doing so.
Any solution using Oracle Service Bus or BPEL would help

HI Birender,
Kindly go through the metalink doc for processsing jpeg/xml/pdf etc any atachement using bpel :Understanding XPATH functions for processing MIME attachments with BPEL PM in SOA Suite 11gR1 [ID 1272093.1]

How to set Mime Type for Static Files

Hi All,
I am working on Apex 3.2.1.00.10.
When I am trying to upload (create) a ".js" file into Static Files under Shared Components of an application; it is saving as "*text/plain*" for Mime Type. But I need Mime type to be set as "*application/x-javascript*".
Please help me to change the Mime type of .js file.
Or is there any way to upload the file directly as "*application/x-javascript*" as its Mime Type.
Thanks in advance.
Umesh

In IIS v4 which comes with the Windows NT4 option pack, you right click the web page you are working with, select properties, then go to the HTTP Headers tab. At the bottom there's a button labelled File Types in the MIME Map section.
After you've clicked that, you can add the two mime types you need;
Associated Extension MIME Type
.jar application/x-java-jar-file
.jnlp application/x-java-jnlp-file
I'm assuming that it is the same in W2k/IIS5.

How to determine mime type of multi-part message uploaded to rest api?

I have a rest api that is used to upload data from different types of clients and serves as a proxy to write data to Azure blob storage. For testing, I'm using Fiddler on a PC.
The code in my rest api that writes to blob storage looks like this:
try
await blockBlob.UploadFromStreamAsync(requestMessage.Content.ReadAsStreamAsync().Result);
catch (Exception ex)
HttpResponseMessage _hrm = new HttpResponseMessage(HttpStatusCode.InternalServerError);
_hrm.ReasonPhrase = ex.Message;
throw new HttpResponseException(_hrm);
1 - How can I access the form-data that is included in the POST that has the original file name and the content-tyipe?
2 - How can this info be passed to the blob when I write it out? Currently, it is written out as a type of application/octet-stream instead of video/mp4.

I think I found a solution using some other threads. I'm not sure if it's the most performant or best but I'm able to get to the content-disposition and the content-type of the stream to get the details:
Dictionary<string, string> lstLines = new Dictionary<string, string>();
string[] _tmp;
TextReader textReader = new StreamReader(requestMessage.Content.ReadAsStreamAsync().Result);
string sLine = textReader.ReadLine();
Regex regex = new Regex("(^content-type)|(^content-disposition)", RegexOptions.IgnoreCase | RegexOptions.Compiled | RegexOptions.Singleline);
while (sLine != ""
&& sLine != null)
if (regex.Match(sLine).Success)
_tmp = sLine.Split(':');
lstLines.Add(_tmp[0], _tmp[1]);
sLine = textReader.ReadLine();

How to Determine Color types in a file?

How can we tell if a document has any CMYK, RGB or Pantone colors within any object (curves, text, etc.)? The requires are just to report that the document has any CMYK and/or RGB and/or Pantone colors. We already can get the color for a bitmap image on the document, it's the other objects on the document.
Thanks...

What I do to make a quick check of a Document is open the Document Info panel. If you want to see what is an object, select only that object, if you want to see what is in all objects select all. In the Document Info panel fly out menu (upper right corner of the panel) select Object to see information on number of objects and what colors are used. If you want to see what Spot Colors are used select the Spot Color Objects from this same fly out menu. Hope this helps but it sounds like you may need more robust preflight tools.

How to determine the MIME types of the files?

I'm making an application, in which I've to upload the files to the database. Now I want to insert into the database the MIME type of the files. Now how can I know that which type of the file is having which MIME type?
where can I get the list of all supported MIME types?
Even if I get the list, then every time I update the file in the database, so every time I have to check the file extension and then insert the MIME type...
this seems to be a tedioius job..
Is there any simple way to do this?

I could ask "supported by what?" but I assume you will
be the one supporting them. Here's a link to the
latest list of registered MIME types.HERE's the link...

How To Get FileType and MIME Type from a File

Hi,
I am using following ways to get FileType and MIME Type.
I am able to get file type, but I am getting MIME Type as */*
Can any one please let me know how to get MIME Type, but it should not be time consuming process.
For File Type I am using following Code:
private String getFileData(InputStream inStream) {
fileName = C:\temp\temp.tiff
String filePath = Util.createTempFile(fileName);
RandomAccessFile raf = new RandomAccessFile(filePath, "rw");
while (inStream.available() > 0) {
     byte[] buf = new byte[inStream.available()];
     inStream.read(buf);
     raf.write(buf);
inStream.close();
raf.close();
File file = new File(filePath);
JFileChooser chooser = new JFileChooser();
String fileType = chooser.getTypeDescription(file);
file.delete();
//MIME Type I am getting from
DataHandler data = new DataHandler(new DocumentSource(inStream));
data.getContentType();
data.getContentType() is not working well in all cases.
Can any one help me on this.
Thanks in advance,
Ram.

//MIME Type I am getting from

data.getContentType() is not working well in all cases.That's because there's no way to get MIME type of all files on all filesystems.

How to determine IE type(32 bit or 64 bit) in a task sequence while updating Java

How to determine IE type(32 bit or 64 bit) in a task sequence
Hi,
Currently i have to update new version of Java after removing all the previous existing version of Java by using TS in SCCM 2007.
we have both 32 bit and 64 bit browser in the environment. I am stucked in determining whether the browser is of 32 bit or 64 bit.
How to determine IE type(32 bit or 64 bit) in a task sequence so that respective java can be installed for that IE browser.
will highly appreciate quick response.
Thanks in advance.
Daya

But you also need to install JRE x86 on x64 systems, since most people actually use the 32bit browsers on x64 systems.
The detection logic is actually pretty simple -- just check the right registry hive to find the installation location of the BIN\JAVA.DLL. Both pathnames are stored in HKLM\Software\JavaSoft\Java Runtime Environment\1.7 in the registry value "JavaHome",
but the x86 path is stored in the 32-bit hive and the x64 path is stored in the 64-bit hive.

(261705413) Q RPCC-21 Missing text/xml MIME-type for WSDL files?

Q<RPCC-21> Would it mess up the SOAP operations that clients do when using the
WSDL in a dynamic client to put a text/xml mime type in the WSDL-providing jsp?
A<RPCC-21>: It is a known issue that the MIME-type for WSDL files is not appropriately
transmitted so some web browsers will not identify an appropriate helper application
when they are viewed (for Netscape just press Ctrl-U to view the source). This,
however, does not affect the dynamic client as evidenced by the example code seen
in the code demonstration.

SR,
You probably already have the answer by now, but I just came across the same problem and found the answer elsewhere.
The trick is to have the JavaMail jar in your classpath BEFORE the JAF jar. Given the habit of my development environment to sort jars alphabetifally it had me stumped for a bit.
Good luck

The type of Raw File used in my Canon 7D MKll is not supported in Bridge, Camera Raw or Photoshop 5S. How can I fix this?

The type of Raw File used in my Canon 7D MKll is not supported in Camera Raw, Adobe Bridge or Photoshop 5S. How do I fix this?

I gather you are using Photoshop CS5? The most recent Camera Raw version that CS5 will accept is ACR 6.7. Support for the Canon 7D Mark II was added in ACR 8.7.1. You will have to use the DNG converter to covert your CR2 files to the universal DNG raw format. Here are the links for the DNG converter:
Adobe - Adobe Camera Raw and DNG Converter : For Windows : Adobe DNG Converter 8.7.1
Adobe - Adobe Camera Raw and DNG Converter : For Macintosh : Adobe DNG Converter 8.7.1

Standard mime type for .acsm file

What is the standard mime type that should be used for an .acsm file?
Is it this? - application/vnd.adobe.adept+xml
I can see few eBook sellers sharing this mime type: application/vnd.adobe.adept (without the +xml). I can see in such cases few of the free reader apps availbale in android / iOS are not recognizing the file.
Pl advice.
Thanks, Sundar

I believe from looking around on the web, just the following is used:
application/xml
Take care, Mike
