Content-Type URLConnection

I need to set my content type to be XML. I used the following:
HttpURLConnection urlConn = null;
URL u = new URL( url );
urlConn = (HttpURLConnection)u.openConnection();
urlConn.setDoOutput( true );
urlConn.setDoInput( true );
urlConn.setRequestMethod("POST");
urlConn.setRequestProperty("Content-Type","text/xml");
Why then does urlConn.getContentType() return text/html;charset=ISO-8859-1?
Liz

Hi Liz,
a call of getContentType() receives data from the net and returns the content type of the fetched data.
"http://www.tutego.com/index.html" -> text/html
"http://www.tutego.com/images/customer-transition.gif" -> image/gif
Best wishes,

Content Type problem

I am trying to retrieve the content type of a file.
String strContentType ="";
          File file = new File(fileName);
          FileNameMap fnmMime        = URLConnection.getFileNameMap ( ) ;
           if ( fnmMime != null ) {
                  strContentType = fnmMime.getContentTypeFor ( "file://c:2.avi" ) ;
System.out.println(strContentType);It works perfect for image, video , sound formats, but it gives null for microsoft office documents and openoffice documents.
can anyone help me?
Thanks in Advance.

"Alternatively you can use ServletContext#getMimeType() for this. It guesses the content type based on the mime mapping as it is been definied in the web.xml of the application server and the webapplication. If it returns null, then you need to add new <mime-mapping> entry to the web.xml."
I would try doing it this way. Try including entries for the mime mappings in the deployment descriptor of the web application.

Setting the correct content type

Hi,
We store files in a database and the actual uploading and retrieving process works very well.
However, when serving a request for a file I would like to set the content type the browser can read.
An example: a httpservletRequest header "accept" comes back with */* - accepting all. Say the file requested is a xls spreadsheet. Since the accept header does not give me any information about the accepted content types, the following possibilities arise for a xls spreadsheet:
- application/excel
- application/vnd.ms-excel
- application/x-excel
- application/x-msexcel
Same thing for power point files (.ppt) and others.
Which of the listed content types do I set as the contentType for the HttpServletReponse so that the browser displays the information correctly?
Whenever possible I would like to avoid the save dialog and display the file inline in the browser.
Thanks for the help,
-Rogier

Here is the complete list of the right MIME types: http://www.w3schools.com/media/media_mimeref.asp
You can retrieve it from filename by URLConnection#guessContentTypeFromName(), or add an extra field to the database which saves the MIME type.
Checkout this FileServlet example for some insights: http://balusc.xs4all.nl/srv/dev-jep-fil.html

URL getContent failing to determine content type

Within my application I am trying to load a file using the URL class. The file is deployed to the web directory /reports/report.txt. If I use the following code it returns to me the message "no content-type" and fails to load the content of the file. I am not sure how to get this to determine the content type or what I need to modify to get this to load the file. Any pointers would be appreciated.
Stirng templateUrl = "/myApp/reports/reports.txt";
URL url = new URL("http", "localhost", 7001, templateUrl);
URLConnection conn = url.openConnection();
logger.debug("content type: " + conn.getContentType());

Does this file exist localhost/myApp/reports/report.txt ?
If it does type in localhost/myApp/reports/report.txt and it should show in your browser.
If not, then yes, you don't have any content there.

Extended Content type problem

Extended Content type problem
I want to extend the content type 'ExtendDocument' from 'Document'.
So I use 'Oracle Internet File System Manager' to create a new Class Object named 'EXTENDDOCUMENT', which is extend from 'DOCUMENT', and add a attribute 'EXTENDURL'.
This Class Object's bean class is 'ifs.beans.ExtendDocument' and server class is 'ifs.server.S_ExtendDocument'.
I create these 2 java class and put the class files to ORACLE_AS_HOME\ifs\cmsdk\custom_classes directory.
As I want to set the object type as 'ExtendDocument' when uploading a file which expend name is '*.wmv', so that need to change 2 default value 'ParserLookupByFileExtension' and 'IFS.PARSER.ObjectTypeLookupByFileExtension'
So I add 'name=wmv, datatype=STRING, value=oracle.ifs.beans.parsers.ClassSelectionParser' to ParserLookupByFileExtension.
And then add 'name=wmv, datatype=STRING, value=EXTENDDOCUMENT' to IFS.PARSER.ObjectTypeLookupByFileExtension.
After done above actions, i restart my oracle application.
I use CUP to upload a test file 'test.wmv' to CMSDK repository, and its type is 'EXTENDDOCUMENT'.
But if I use FTP or WebStarterApp application to upload 'test.wmv' file to CMSDK repository, then its type is 'DOCUMENT'.
Why and how to change to make FTP and WebStarterApp application can upload *.wmv file's type as 'EXTENDDOCUMENT'?
anybody can help me?
thanks.

Not able to crawl all items from External content type

Hello All,
"All the records in my external content source are not getting crawled, only 1/3 rd of the data are getting crawled."
Steps:
I created "External content type" using sharepoint designer which connects to a SQL Server database.
Have written a SQL View joining 2 tables, which return 9,00,000 rows when executed using the SQL Server management studio.
I used the default "Business Data Connectivity Service" and "Search Service Application" and made sure the necessary permissions are set.
Created a External Content source for the search service application and selected the "Business Data Connectivity Service" -> "Crawl selected External datasource" -> <my external datasource i created in sharepoint designer>
Issue
When i ran the full crawl for the first time it crawled "3,49,923" records in 01 hour and 07 seconds. And returned 1 error "Error crawling LOB Contents.(Error caused by exception: System.InvalidOperationException. There is an error in XML
document...)
Later i removed the below item from the index and started a full recrawl, this time it crawled "3,49,924" records 1 record extra from my previous crawl
and no errors were returned.
Please let me know what could be the issue. It doesn't look like the permission related issues as i am able to crawl the 1/3rd of my total data. Also i am able to search the crawled data. I also set the throtteling limit for the "Business data catalog"
to -maximum 10000000 -default 1000000 which is less than the data it has to crawl.
SRIRAM

Hi ,
I started the change suggested in the link shared by you, but got stuck at a point,
The field which i set as identifier in BCS earlier is not having unique values. Total rows returned by the sql view is 899000, but the unique values present in the column that is set as identifier is
3,49,923, which is equal to the number of rows crawled. - Is this the reason why it didnt crawl all records?
The table that is used in the sql view has composite key, - Is it possible to have multiple identifier in BCS as well?
Is it possible to make BCS to ignore the identifier? i mean creating BCS without an identifier column?
Please let me know your suggestions on this.
Thanks,
SRIRAM
Yes, BCS needs a UID. This is so it can figure out changes over time to a single record. Otherwise all changes to a row could be a potential new row without BCS knowing any better.
Yes, or just have it run off the composite key instead of the field you're using now.
Nope, BCS needs a UID field like in answer 1 :)
Good luck!

Cannot add hub-managed content type with external list lookup columns to a list -- Error:Id field is not set on the external data field

This is a variation on the issue mentioned in this
post
We are using SP 2010 Content Hub to manage our content types. On the content hub we've created a couple of exteranl lists, and then created some site columns as lookups against these lists. We then added the columns to one of our content types
and set it to publish.
After the publishing job executed, I tried adding the content type (which now appears on the subscriber sites) to one of the document libraries on one of the subscriber sites. When I did that it threw the following error:
Microsoft.SharePoint.WebControls.BusinessDataListConfigurationException: Id field is not set on the external data field

I checked the external content type configuration and it did specify an "id column". Anyone know if what I am attempting to do is possible and if so, what special configurations are required?
Thanks

The issue is not External Content type or external list but the look up column.
It's not possible to publish a look up column via the Content Type Hub.
If you need to do this then an alternate way is to use a Managed Metadata column instead, otherwise you will have to implement this via a feature.

Problem with content type

Hi All,
I have set the content type to text/html by using the following statement in jsp
<%@page contentType=�text/html�%>And if I give
out.println("<a href="aaa.do">Click here</a>"); it is showing me a link to click here that's fine.
But my problem here is that I am using struts <bean:write name="user1" property="subject"/> tag and the data in the subject field is Click here i.e the output from the database, now its not showing the link instead displaying every thing even if the content type is set. How can I achieve this? please help me out.

in your bean:write tag try setting the filter attribute to false, like so
<bean:write name="xxx" property="xxx" filter="false"/>

Versioning and Video Content type does not work.

Hello,
I have out of the box sharepoint installed.
When I apply versioning to a library. And try to see "Document set version history" (as I suggest Video content type actually inherits from Document Set). I don't see any version.
Can you tell me how can i see versions of the "Video" content type item in this Version History window?

Document set versions are slightly different than item versions. Document sets can be managed by a separate ribbon tab called Document Set and group called Manage.
Check below link for detail go through:

Hello good day i'm trying to create a report that will be preview under A/R Invoice but the details need is under delivery module for example i create a serialize Item and set the Management Method on Every Transaction Under Item master data, so the transaction flow will be like this SO -> Delivery -> A/R Invoice. So under delivery transaction i will choose the serial that i will deliver so that under A/R Invoice Transaction i will no longer choose again the said serial that i choose on Delivery Transaction. There for on my Report i will Based on Delivery Transaction to get the chosen Serial But the Report will be Preview under A/R Invoice.
