No Content type in header error

Hi
getting the error "No content type in header" after i gave credentials in my home screen .
But i can able to run generic application
and while starting my jdev am getting some firewall warning messages
as "Windows firewall blocked some of the features of jdev on all public ,private and domain networks"
Is there any connection between these too ??
Please help me in this
TIA

User, How should we possibly answer this?
You not even shared the minimal information like jdev version. What kind of application is it? Credentials mean security. Which kind of security?
Reading your stack trace I see 'portal', 'webservice', 'ADFC-10001: cannot instantiate class 'com.smartworkplace.reseravations.home.HomePageReservations' so there are plenty of hints for you to follow up.
For us to help you need to provide more detailed information.

Setting webservice response content type / charset header

I have a webservice .war file.
I need to set the content-type/charset http header and add another http header. I wrote a filter to do that and had partial success. The other header (pics-label) is indeed sent in the response with the correct value. However, setting the content type proved to be another matter.
I read through the documentation that one can set the system property weblogic.webservice.i18n.charset=utf-8. However, this doesn't seem to work. The filter setting the header also doesn't work. It seems that weblogic has the final word on that. Only when I set the <web-service> element attribute charset="UTF-8" does the header gets back to the client.
Due to deployment/build related issues which I won't get into, this is most annoying.
If anyone has encountered a similiar issue and have a solution/workaround/thoughts I'll be glad to hear about it.
P.S.
Also tried -Dfile.encoding=UTF-8 but didn't do any good.
Thanks.

you don't define a charset for non-text file types. Excel files are not text files.

Tomcat always generates charset in Content-Type http header !!!

Dear All! I need urgent help with a problem I met with and any suggestion are very appreciated!
The problem is:
We are using Tomcat as a web server (and JSP engine), and we would like to use a user control written in C# 2.0 on one of our pages. I've developed such component and tested it using JBuilderX (in fact it resides inside a JSP page). Everything is working fine while debugging using JBuilder, but when I tried to deploy the solution - I got a problem, my dll was not downloaded properly. Let me illustrate this with a test example. I wrote a test html page:
<html > <head> <title>Test</title> </head> <body> <object id="MyControl" height="300" width="550" classid="http://localhost:8080/MyDLL.dll#WindowsControlLibrary1.UserControl1"> </object> </body> </html>
When I tried to open it I did not get my control loaded. I check the headers of the server http response and found that Tomcat added the following string as
Content-Type: application/x-msdownload;charset=ISO-8859-1
I'm positive that in this case Content-Type should look like
Content-Type: application/x-msdownload
(or application/octet-stream if I would choose to define mime type for dll in server's web.xml as
<mime-mapping> <extension>dll</extension> <mime-type>application/octet-stream</mime-type> </mime-mapping>
- it does not matter as I understand )
so Content-Type should not contain any charset for DLL part of response. NO charset=ISO-8859-1 !!
But Tomcat adds it. :-( And I don't know how to prevent him doing that.
On the other hand when I tried to open this page using Tomcat started from within JBuilder (port number in this case is different) - then everything was going good and control was downloaded to "Temporary Internet Files" and shown on the page.
Content-Type field in this case was:
Content-Type: application/x-msdownload
without any charset.
So, my question is: How to suppress Tomcat wish to add the "charset=ISO-8859-1" string to the Content-Type http response header?
What should I do to load my test html page succesfully?
Thanks in advance for you time and patience!
Sincerely yours, Igor

Setting content-type response header in BlazeDS

Per this JIRA ticket, http://bugs.adobe.com/jira/browse/BLZ-428 , there is a suggested fix that includes setting the response content-type header to text/xml.
The JIRA ticket name is
pinging endpoint Returns a HTTP: Status 200 in ie8
and the suggested fix is:
The problem appears to be completely worked around by setting the following headers in our HTTP responses to Flash:
Content-Type: text/xml; charset=UTF-8
Cache-Control: no-cache
What is the best way to do this is if using BlazeDS?
I have tried to set the content-type within my data service desitnation class, by accessing the HttpServletResponse from the FlexContext class, however this does not work. The content-type is still "application/x-amf" in the response. I am assuming that BlazeDS sets the content-type sometime after my data service desination code is invoked.
I have also tried to create a servlet filter and set the content-type header both before and after (in a finally block) my data service code is invoked, however neither of these approaches successfully ended up with a content-type of "text/xml" in the response. My sense is that setting the content-type prior to the data service destination code is too early in the chain and setting in the finally block is too late (per the servlet spec you cannot set the content-type after getWriter() has been called).
Any ideas are appreciated.
Also any other ideas on how to solve the general IE8 issue described in the bug above are appreciated.
I am using...
BlazeDS version: 3.2.0.3978
Flex SDK version: 3.4
App Server: JBoss 4.5
Java: 1.5_16
Thanks,
Kevin

Hi,
in the meantime I found a "known issue" that seems to be related to my problem but it is said to be fixed with 10.0 MP1 (and we use 10.3):
ChangeRequest number: CR316761, CR318708
Description. The servlet container used to append charset=ISO-8859-1 to the HTTP Header contentType in the response for non-JSP pages with any charset contents. This would result in improper display of multibyte characters.
This problem has been resolved.
Maybe the information is wrong. I will examine the CR and may apply them on our 10.3 environment but I would be glad if some oracle/bea engineer would intervene here.
Cheers

Mapviewer SVG and Content-Type http header

Hello,
We have a Mapviewer installation that seems to be serving up the wrong Content-Type header for the SVG charts. The map is being created correctly and we can get GIF's and such.
The wrong Content-Type causes the Adobe SVG viewer to never render the SVG map successfully. When I save the SVG file to the desktop it opens perfectly or if I statically link it in to the web page from the sever it also opens perfectly. Is there some configuration that is missing somewhere on the mapviewer or the application server to correctly set the Content-Type ?
Notice the content type of the failing map compared to a working SVG chart we have.
HTTP/1.x 200 OK
Content-Length: 41979
Cache-Control: private
Content-Type: application/octet-streamConnection: Keep-Alive

Content-Type: image/svg+xml; charset=utf-8Connection: Keep-Alive

This seems to be the last sticking point in successfully rolling out this mapviewer implementation. Any help would be greatly appreciated.
Thanks, in advance.
Thanks,
Carl

Hello,
Thanks for the reply I've tried both SVG_URL and SVGZ_URL and used a http header sniffer to watch what's getting served up and the urls associated with MapViewer SVG are definitely getting served up with that wrong Content-Type.
Our front end is an Oracle APEX environment were we use APEX's SVG charting on the same page and they are getting served up with the correct Content-Type and display correctly, which is nice cause I can watch the header difference's side by side, and we know the mapping itself is working right because we can get image files back
Is there a sever config file or something like the httpd.conf for apache that needs to be set?
Thanks for any help or insight

Set content type on header doesn't work on servlet filter

I am trying the following filter:
chain.doFilter(req, responseWrapper);
and im trying to set the content type:
response.SetHeader("Content-Type","text/plain");
But it doesn't seem to set it.
I have the wrapper as:
private ByteArrayOutputStream     output;
     private int                              contentLength;
     private String                         contentType;

     public void setMode(int mode) {
          this.mode = mode;
     public String toString() {

Multiple "Workflow Task (SharePoint 2013)" content type found

Users on one specific sub-site reported that they are unable to add site columns to content type. When user clicks "add existing site column" user get error message - upon looking up on ULS, it indicate there were duplicate column "System.ArgumentException:
No two choices should have the same ID". I came across similar issue on different site before and resolved it by deleting duplicate column, plus that site column was not used on any list or associated with any content type but this time duplicate
column is "Task outcome" column which is associated with "Workflow Task(SharePoint2013)" content type. So looking up these two specific site column and content type I noticed there are 8 occurrence of each at affected site
level (see below on image).
Similarly there are 8 "Task Outcome" columns under Site Columns. So I refreshed staging env with prod copy and tried to delete "Workflow Task(SharePoint 2013" content type and got error message as shown below. Under Site features, I noticed
"SharePoint 2013 Task List" feature was enabled, hoping this will do the trick I disabled it as we still use SharePoint 2010 workflows, but to no avail.
Sorry, something went wrong
The content type "Workflow Task (SharePoint 2013)" is part of an application feature.
Not sure how it got started and something will try to find out but any advise on how to fix this issue?
Thanks,
MK Sin

Hi Sin,
According to your description, my understanding is that the users got an error when clicking “add existing site column”.
For deleting the duplicate “Task outcome”column, you need to go to the “Workflow Task(SharePoint 2013)” content type, click the “Task outcome” column, and remove it from the content type.
Then go to site columns, find the duplicate columns, and delete them and make sure only one “Task outcome” column exists.
After the above, re-add the “Task outcome” into the “Workflow Task(SharePoint 2013)” content type.
Best Regards,
Wendy

Hi,
We can use the following PowerShell script to create a page content type.
$spWeb = Get-SPWeb http://sRVR1:123/sites/ENGG/
$spWeb.AvailableContentTypes | Select Name
$parent = $spWeb.AvailableContentTypes["Page"]
$contentType = New-Object Microsoft.SharePoint.SPContentType -ArgumentList @($parent, $spWeb.ContentTypes, "BIFPageCT")
$contentType.Group = "My Content Type"
$contentType.Description = "BIF Page Content Type"
$spWeb.ContentTypes.Add($contentType)
$spWeb.Update()
$spWeb.Dispose()

Powershell to add/delete content type to particular library alone in a site collection

Hi,
I am trying to add and delete content type from a particular picture library (site collection) using powershell.
I have tried the below, but it is not working.
Below scenarios are not working:
1) If the content type to be added is there in library, then the loop is still moving to "No content type exists".
2) Content type is not getting deleted from library
3) Set the newly added content type as default content type.
Below is the powershell, which I am trying:
function ChangeContentType($url)
$site = Get-SPSite($url);
$web =$site.RootWeb
$lookForList = "PicLibrary"
$lookForCT = "Img1ContentType"
$lookForRemoveCT = "Image2CT"
write-host "Checking site:"$web.Title
#Make sure content types are allowed on the list specified
$docLibrary = $web.Lists[$lookForList]
if ($docLibrary -ne $null)
$docLibrary.ContentTypesEnabled = $true
$docLibrary.Update()
if (($web.ContentTypes | where { $web.Name -eq $lookForCT }) -eq $null)
write-host "No content type exists with the name" $lookForCT "on list" $docLibrary.Title
#Add site content types to the list
write-host "Adding content type " $lookForCT "on list" $docLibrary.Title
$ctToAdd = $web.ContentTypes[$lookForCT]
$ct = $docLibrary.ContentTypes.Add($ctToAdd)
write-host "Content type" $ct.Name "added to list" $docLibrary.Title
$docLibrary.Update();
else
write-host "content type exists with the name" $lookForCT "on list" $docLibrary.Title
#Remove Content type
if (($web.ContentTypes | where { $web.Name -eq $lookForRemoveCT }) -eq $null)
write-host "No content type exists with the name" $lookForRemoveCT "on list" $docLibrary.Title
else
$ctToRemove = $web.ContentTypes[$lookForRemoveCT]
write-host "Removing content type" $ctToRemove.Name "from list" $docLibrary.Title
$docLibrary.ContentTypes.Delete($ctToRemove.Id)
$docLibrary.Update()
else
write-host "The list" $lookForList "does not exist in site" $web.Title
#Dispose object
$site.Dispose()
$web.Dispose()
How to fix this?
Thanks

Hi,
Thanks for the reply.
I checked it. If the script is run multiple times, the add and delete content type will throw error.
How to delete content type? I have tried the below:

$docLibrary.ContentTypesEnabled = $true
$docLibrary.Update()

Site content types and site columns were absent

hi,
i have seved a sub site as a template which includes 20+ doc libs with 20+ site content ctypes which includes 15+ site columns and then i have used this savedsite template in one site collection and implemented my
custom web parts and upload document fun. successfully.
now i have created another new site collection and forgot to create site content types and site columns as we have seen the site columns in the saved site template already.
now i realized that those site content types and site columns were not there but the strange thing is that i am able to uplaod the documents into those document libraries which are not associated with site content types, without any error.
Can I create the same in my new site collection ? since i have already created many many sub sites based on the saved site templates tested the functionality ,i dont wanna delete the template recreate all the sites again in order
to save the time.
Now pls advice:
1) if site columns / site contents were not existing at the site collection level, will this affect my func. in future?
2) is there any automated way fo creating site columns, site content types, associateing these site content types with doc libs programmatically like power shell/ sp object model API.
3) would like to any programmatic way of creating hundreds of sub sites based on the saved site templates in myw eb application/ site collection.

Change Content Type Hub URL -- AAM Configuration

Hello, we initially setup our SHarepoint Web Application with Default Zone URL https://sharepoint2.contoso.com. We created a Content Type Hub and configured the URL https://sharepoint2.contoso.com/...... in the Managed Metadata Service Application.
We now changed the URL for the Default Zone to http://sharepoint.contoso.com and the last thing to change now is the URL of the content type hub.
My Question is what exactly will happen when i set the new HUBURI with powershell?
We have published the content types from the hub with the old URL to many site collections and are using them for over 1.000.000 documents. I want to ensure that there will be no impact on the existing content types. Will there be any impact. Will they get
unpublished?

Hi UTTO,
According to your description, my understanding is that you want to change the URL of publishing Content Type hub.
In SharePoint, we should use only one certain zone to publish content type. If you change the URL to http://sharepoint.contoso.com in the Managed Metadata Service Application, you will not publish content
type via https://sharepoint2.contoso.com , and maybe get an error like “No valid proxy can be found”. You should only publish content type via
http://sharepoint.contoso.com .
A similar posts for you to take a look at:

I hope this helps.

Cant delete orphaned content type, it says : "The content type is part of an application feature."

I created site from existing site template that previous vendor working with company created. I could figure that they saved site as template and when you do that sharepoint creates sandboxed solution. When I create site based on that template, it adds orphaned
content type and when I try to delete it, it gives error : "The content type is part of an application feature.".
I looked on internet but solutions dont seem to fit in my scenario.
Following are possible solutions I read on net.
1) Deactivate feature that has content type and all dependencies for content type and then delete content type --- In my case there is no feature in feature galary that you can deactivate as it is part of site template.
2)Get the WSP and edit in visual studio, I am working on client machine and I do not have access to sharepoint server. When I try to create new visual studio project with "Import sharepoint solution package", it says Sharepoint server is not installed
on this computer. I tried to get Microsoft.Sharepoint dll from Microsoft virtual lab but I can only work on web client and windows client doesnt work. Web client is not letting me copy files into my local desktop.
Any suggestions ? I just need to take that content type out and generate WSP and upload it back

Below is how I recreated problem , my findings and solution to this problem (Everything is done through Sharepoint UI)
Problem :
Create site and create custom content type using sharepoint UI.
Save site as template.
Use above template to create new site.
New site contains orphaned content type, when you try to delete that unnecessary content type sharepoint gives error: The content type is part of an application feature. Sharepoint will not let you delete this content type.
Delete original site from which template was created.
Findings:
When you save site as template, sharepoint creates and activates Sandboxed solution in solution gallery of Root Site.
Sandbox solution has same name that you gave when saving site as template.
Activation of Sandboxed solution adds feature having name of original site from which template was created, and this is Site Collection Feature. I could not find any site feature for it and also I could not find any site feature for custom content type
as well. I think when you create content type through Sharepoint UI, it doesnt create site feature for that.
Deactivating site collection feature for that site template doesn't let you delete that orphaned content type from newly created site.
Solution:
If you deactivate Sandboxed solution from Solutions gallery, it will remove corresponding site collection feature as well as that orphaned content type from site. Reactivating that solution doesn't add orphaned content type back to newly created site.
Above process only deletes orphaned content type from newly created existing site but you will have same problem when you create more new sites from that site template.
I would say once your problem is fixed with deleting content type, solution is to replace site template. In this way newly created sites wont have same problem again.

Hi,
I am trying to access an XML WebService. This service requires the content type of the request to be set to "text/xml". As you can see in the source code, I am setting the req.ContentType property to "text/xml".
However, this content type seems not to be added to the HTTP headers. The server returns a 400 Bad Request error as can be seen in the log.
I've attached a System.Net.trace log and it states:

...and here's the implementation of the web request:
private void ButtonSend_Click(object sender, EventArgs e)
WebHeaderCollection whCol = new WebHeaderCollection();
whCol.Add("API-VERSION", "1");
//whCol.Add("Content-Type", "text/xml; charset=UTF-8"); <-- That doesn't work in .NET. Content-Type has to be set on the ContentType-Property
string msg = _textBoxReq.Text;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(_textBoxURL.Text);
byte[] data = Encoding.UTF8.GetBytes(msg);
req.Method = "POST";
req.ContentType = "text/xml; charset=UTF-8";
req.ContentLength = data.Length;
req.Headers = whCol;
req.GetRequestStream().Write(data, 0, data.Length);
string xml = "";
try
using (HttpWebResponse resp = (HttpWebResponse)req.GetResponse())
using (System.IO.StreamReader sr = new System.IO.StreamReader(resp.GetResponseStream()))
xml = sr.ReadToEnd().Trim();
catch (WebException we)
using (System.IO.StreamReader sr = new System.IO.StreamReader(we.Response.GetResponseStream()))
xml = sr.ReadToEnd().Trim();
_textBoxRes.Text = xml;
Can anyone help?
Thanks,
