Returning content type of application/RFC822
I have a servlet which needs to return a data stream that the browser
shoule save as a file on the users local hard drive.
My servlet seems to work just fine with Netscape 4.7 but IE always saves
the original HTML Form page that called the Servlet.
Is there a bug in WL/IE or am I doing something stupid
here's my code - the method doing returning the data is the last one in
this code - getResponseFromDispatch()
Thanks
Tom

There is also a bug in IE5.5 SP0 and 1 where saving a document using the file download
dialogue can indeed result in the HTML of the active frame being saved instead
of the document.
You can get IE 5.5 SP2 fix here:

URL Manipulation when content-type is application/json (with UAG 2010)
Hey,
I got a website published through HTTPS trunk (UAG2010) which works with "application/json" content type at some parts (AJAX objects).
The parts which use applicaton/json content-type are loaded with a bad URL's on the client side (the internal URLs)
How can i configure that UAG will manipulate this content-type? (so the HAT mechanism will manipulate these get requests and responses)
Thank you, Idan.Hi Idan,
We had a similar issue with internal links not being translated for a particular UAG published website. You'll need to run fiddler or httpwatch from a UAG client to identify the failing URL link extension types, eg .jsp and .RF
Open the trunk configuration, and select the portal tab, click
edit under Search and Replace Response Content.
Under Servers, put the fqdn of the web server / publishing address, and under URLs, add the identified extensions.
We also had to have a custom WhlFiltSecureRemote_HTTPS.xml file created under
Von\Conf\Websites\%trunk_name%\conf\CustomUpdate
which included the defined application type for the published website, and tells UAG when to use the search and replace parser.
Hope that helps.

Content-type: application/xml and Application server 9
I have a web service running on Application server 9, implemented using netbeans and JAX-WS.
When a client sends a request to it with:
Content-type: application/xml
the request is rejected because the server does not recognise the mime type.
Specifically, the response is:
HTTP/1.1 415 Unsupported Media Type
X-Powered-By: Servlet/2.5
Content-Type: text/plain; charset=iso-8859-1
Date: Fri, 01 Sep 2006 14:49:04 GMT
Server: Sun Java System Application Server Platform Edition 9.0
Connection: close
Everything works fine when the request has:
Content-type: text/xml
Is there a way to make my web service accept content type of 'application/xml'?
-Tony Beaumont
Aston University
beaumoajI have fixed this for myself, i.e. decompile, replace in jar.
My problem was that most tools define the encoding but code was simply testing
if( contentType.equalsIgnoreCase( "text/xml" ) )
so sending xml from other tools that send contentType
"text/xml;encoding=UTF-8" or some such, like soap tools, would mean no XML was seen.
Is the proper source available for XSQL? -
Apex_web_service.make_rest_request: Passing parameters and the content type
Not sure if I am missing something, but should this API be setting the content type (to application/x-www-url-formencoded) when there are values present for the parameters p_parm_name and p_parm_value.
The example in the docs is to a yahoo API. I'm not sure about that particular one (see: http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21676/apex_web_service.htm#BABEDJHJ), and I think it requires an appid (yahoo account), so i just went with the example here:
http://developer.yahoo.com/yql/guide/yql-code-examples.html#yql_php
If I run the following from a html file on my desktop it works:
<form method="POST" action="http://query.yahooapis.com/v1/public/yql">
<input type="hidden" name="q" value="select * from upcoming.events where location='San Francisco' and search_text='dance'"></input>
<input type="hidden" name="format" value="json"></input>
<input type="submit"></input>
</form>That is, it returns a JSON result.
The raw HTTP data is as follows:
POST http://query.yahooapis.com/v1/public/yql HTTP/1.1
Host: query.yahooapis.com
Connection: keep-alive
Content-Length: 110

However, running the following returns nothing: (nothing, as in nothing that depends on the parameters passed in)

I do note a key difference is that content type isn't being set in the web service API.
This was just to test a public service. I do note that the above has slighty different request data (percentage encoding on some chars). However, I experienced the same behaviour on a procedure I had written (I can also provide this example test case if you like), which is where I first noticed the issue.
Using utl_http and setting the content type to application/x-www-url-formencoded, does resolve the issue. However, just thought i'd see the possibility of using the Web service API that is made available.
Is the example in the docs valid, or am I missing something obvious?
This is on ApEx 4.1 on the OTN Dev Days VM.
Thoughts?Hi trent,
I too have had issues with this API , so moved forward with UTL_HTTP API.
There is something amiss.
If you change your code to the one below it works.
SET SERVEROUT ON
declare
l_c CLOB;
l_param varchar2(1000) ;
begin
l_param := 'select * from upcoming.events where location=''San Francisco'' '||
' and search_text=''dance'''||'&'||'format=json';
l_c := apex_web_service.make_rest_request(
p_url => 'http://query.yahooapis.com/v1/public/yql?q='||
utl_url.escape(l_param)
,p_http_method => 'POST'
dbms_output.put_line(substr(l_c, 1, 4000));
end;
/Note the use of UTL_URL.ESCAPE. The call does not work without it.
I do not use a proxy, so that parameter does not feature in my snippet above.
Cheers,
PS: However, the below does not work. So, it appears that the p_parm_name and p_parm_value do not quite work.
SET SERVEROUT ON;
declare
l_c CLOB;
l_param varchar2(1000) ;

Email attachments content-type
Hi guys,
I have one process that starts with an email agent. When I send an email with a txt file in attachment the email agent set the content-type to "text/plain" but if i send an email with a lst extension file the email agent set the content-type to "application/octet-stream". I need that the email agent set the content-type "text/plain" to the files with lst extensions.
BPEL version 10.1.3.5.
Any idea?
regards
Rodrigo Zuchetto
Edited by: Zuchetto on Feb 11, 2010 3:45 PMHi,
we don't found the solution for this problem but a workaround that resolve - temporarily - our problem...
- first we source in different places how to set mimtype content. Unfortunately we don't found were BPEL/SOA take the value to attribute the mimetype of a specific file (we change the mimetype content of operation system - Windows/Linux -, JVM, SOA and others).
- we discover that MailActivationAgent convert unknown file extensions to application/octect content-type.
- with this info, we implemented into our BPEL flow a Java Embeded to re-convert the file content (using this reference: ora:readFile returns strange string
Now we are sourcing for a specific solution: this Java Embeded workaround don't accept setting a different charset. If we have different characters this cause a problem when file are re-converted. But, for now, this workaround resolve our problem.

Weblogic Portal - Disc API bug in response content type
Hi
While using WLP Disc APIs in the portal for AJAX calls, the response content type returned by the weblogic portal server is:
text/x-netuix-json-comment-filtered; charset=ISO-8859-1
This is not getting changed to 'application/json' inspite of setting this as the content type for a JSF JSP.
Probably, looks like a bug.
We have a JSF portlet in which we need to make an AJAX call.
Please refer to the weblogic whitepaper for the AJAX examples (weblogic-portal-jsf-whitepaper.pdf).
The example works fine in the dev/build environment. When the portal server is accepting calls through Sun One webserver,
the logs from the webserver show the response content type from the portal server as "text/x-netuix-json-comment-filtered; charset=ISO-8859-1"
- I tried changing the content type to "application/json" in the JSF JSP (as per the example from the pdf file). Still the content type does not change.
- The response from the portal server is suffixed with "\n\r\t". Because of the trailing space/carriage return chars in the portal server response, the sun one webserver is unable to parse (or) eliminate the "\r\n\d" chars to the browser. When the browser receives a response (with the trailing chars), the module.js (weblogic wrapper API for DISC calls) fails.
- The module.js tries to check whether the response from portal server ends with "**/" but unfortunately, the weblogic protal server returns
"/** %json response%**/\n\r\d"
I found a workaround to this issue by having a filter for the JSF JSP which sets the content type as "application/json" and does a flush() before it makes a call to the JSF JSP which responsds to an ajax call. This works as the content type is set and flushed first so any attempt by the portal server to set as "text/x-netuix-json-comment-filtered" does not get reflected in the http response.
Any support/fix from oracle regarding this will be helpful as most of the webserver integration with the portal server happens during the middle of the project build and might lead to a technical risk.
Server details: WLPS 10.3, Sun One 7.0
Thanks
Ananth KrishnanMake sure you're using the Reverse Proxy Plugin for Web Server, not the Application Server Connector (they are VERY similar, but not the same). The RPP knows how to handle 100 Continue, the Connector does not.
Or use Web Server 7 and its built-in reverse proxy feature. -

Ananth KrishnanThe problem as you can see is only related to the URL because the webservice is not expecting the URL. Have you changed the wsdl also for the new scenario? The URL can be rechecked to the one present in the wsdl at bottom of it.

Sun BPEL engine sets wrong Content-Type on calling an external web service
I have a WSDL for an external web service (which as it happens is running in Websphere locally) and have implemented it as a
partnerlink on a BPEL diagram in an SOA composite project. The binding style is Document and if you use SOAPUI to test it it
works fine. Tracing on the web service's server shows the SOAP request coming in. It has a content-type of text/xml, as expected. If I do a JUnit test from NetBeans based on this WSDL alone it also works - same result. BUT if I do
a full test and call my BPEL process the invocation of this service from BPEL fails.
On the Test result you see
BPCOR-6135:A fault was not handled in the process scope; Fault Name is http://www.sun.com/wsbpel/2.0/process/executable/SUNExtension/ErrorHandling}systemFault;
(This happens because I did not handle the fault in the BPEL.)
On the trace I see it now has Content-type of application/xop+xml. Why would the Sun BPEL engine change this? I just
accepted the usual defaults when I created the PartnerLink and the Invoke. Anyway, the format of the request doesn't match what the WS server expects, so it fails.
As far as I'm aware I'm just using SOAP1.1. This is NetBeans 6.5 with Glassfish 2.1. I tried with NetBeans 6.7 and it got worse, not better. I would certainly appreciate any advice?
ThanksPerhaps when the BPEL file based process calls the WSDL file to execute,their message communication is not correct.
the head part in the WSDL file should be manually set to "text/xml", or the IDE or Server will use the default value;
for example as follow:
SOAPUI tool would use the default value "text/xml" to request.(depends the tool support).
NetBeans tool would use the default value "text/xml" to request.
when you do a full test and you do not set the head "context-type" value ,the WSDL file use the server's default head
value"application/xop-xml" so that return the contents under the control of the server's default value.
I hope these will be useful for you. -

Using Forms that don't set the content type charset
The Servlet API 2.3 has a new method, request.setCharacterEncoding(), to
deal with the fact that almost no browsers set the content type. When I call
this method passing "Shift_JIS" using weblogic 6.1, it works fine when the
content type is not set by the browser. That is, after calling
setCharacterEncoding when I call request.getParameter("testparam") I get the
correct translated value. However, if the content type is
"application/x-www-form-urlencoded; charset=Shift_JIS" and I call
request.setCharacterEncoding("Shift_JIS"), getParameter("testparam") returns
null.
Can anyone shed some light on this?
It looks like I'll have to not set the character encoding if it is already
set. That, of course, opens the possibility that the character set used for
translation is different than was used in the form.

It might not be the new 3G network. Though I've heard the major metropolitan cities can have slower responses due to congestion.
Have you upgraded to the new operating system? Have you tried resetting your phone? You can do that by holding the "Home" and "Power" buttons down together, through the shut down screen and until the apple appears on the screen.
You might also try this:

Content type in SOAP receiver communication channel
Hello,
so far I thought that the SOAP receiver adapter always sets the content type to text/xml. However now I found out the following strange thing:
If you check the option "without SOAP envelope" then the content type is application/xml. Is there any way to influence this as the receiver of the message only accepts text/xml.
Have you had any similar experience?hi,
- open SOAP receiver communication channel - module tab
- add the module "localejbs/AF_Modules/MessageTransformBean" or AF_Modules/MessageTransformBean" before the standard SOAP module
- add the parameter = Transform.ContentType with value = text/xml
I'm just not sure if you need to add value = text/xml or "text/xml" so try the second one if the first one will not work
does it work now?

Cfhttp and setting the content-type for a request
Hi,
I am trying to set the content-type for a cfhttp request like this (on coldfusion 9):
<cfhttp redirect="no" method="get" timeout="120" url="http://10.0.0.1/test2.cfm">
<cfhttpparam type="HEADER" name="Content-Type" value="application/json; charset=utf-8">
</cfhttp>
// coding on test2.cfm:
<cfset x = GetHttpRequestData()>
<cfdump var=#x#>
// Output on test2.cfm
content
[empty string]
headers
struct
Accept-Encoding
deflate, gzip, x-gzip, compress, x-compress
Connection
TE
Host
10.0.0.1:80
Proxy-Connection
close
TE
trailers, deflate, gzip, compress
User-Agent
ColdFusion
X-REWRITE-URL
http://10.0.0.1:80/test2.cfm
method
GET
protocol
HTTP/1.1
As you can see no content-type is send through. I also tried the sniffer.exe:
GET http://10.0.0.1:80/test2.cfm HTTP/1.1
Host: 127.0.0.1
Proxy-Connection: close
Connection: TE
TE: trailers, deflate, gzip, compress
User-Agent: ColdFusion
Accept-Encoding: deflate, gzip, x-gzip, compress, x-compress
Here you can also see that no content-type was passed through. The sniffer should report back
GET http://10.0.0.1:80/test2.cfm HTTP/1.1
Host: 127.0.0.1
Proxy-Connection: close
Connection: TE
TE: trailers, deflate, gzip, compress
User-Agent: ColdFusion
Accept-Encoding: deflate, gzip, x-gzip, compress, x-compress
Content-Type: application/json; charset=utf-8
But is does not, what do i need todo to set the content-type in a cfhttp request.
Kind regards,
Nebu12Robots - are you sure about your statement that GET method requests cannot have Content-Type headers? I don't think that that is correct. I've always thought that it was valid (maybe unusual, but ...) and this W3C link weems to agree, especially in the context of its comment about what Content-Type means in a HEAD method request: http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html
The big problem with trying to get around the CFHTTP limitation by using the CGI scope is that the dash is illegal in a CF varname.
There is a custom tag called CFHTTP5 that getsaround a lot of the CFHTTP limitations, including cookie preservation across multiple requests. I haven't used it for a long time (CF5), but it is still actively developed. Costs $50 - http://www.cftagstore.com/tags/cfxhttp5.cfm

your site http://balusc.xs4all.nl/srv/dev-jep-pdf.html helped me a lot.
But one point. There is another method : URLConnection.guessContentTypeFromStream(InputStream)but it don't work and i receive as result a null.
Is there another classes/methods which helps getting the content type of a file? not necessarily from sun. thanks
