Unforce HTTP headers in WL Servlets

Is there a way to force the Servlet to not set the "Content-type" header, or any
          header for that matter? I am having problems printing cookies and setting a
          location. Whenver I use setHeader or sendRedirect, I no longer can send
          cookies.I tried using the ServletOutputStream and print "Location:..." and
          "Set-Cookie:..." for each one of my cookies, but "Content-type" is set
          automatically and I get my header settings displayed verbatim.
          Has anyone ever ran into this problem? Is there a workaround? Any help would be
          appreciated.

No, I just had some problems with cookies that were only solved by
          introducing the handling I described below and thought it might be helpful
          for you to try something similar.

Generate PDF using Managed Bean with custom HTTP headers

Background
Generate a report in various formats (e.g., PDF, delimited, Excel, HTML, etc.) using JDeveloper 11g Release 2 (11.1.2.3.0) upon clicking an af:commandButton. See also the StackOverflow version of this question:
http://stackoverflow.com/q/13654625/59087
Problem
HTTP headers are being sent twice: once by the framework and once by a bean.
Source Code
The source code includes:
- Button Action
- Managed Bean
- Task Flow
Button Action
The button action:
<af:commandButton text="Report" id="submitReport" action="Execute" />
Managed Bean
The Managed Bean is fairly complex. The code to `responseComplete` is getting called, however it does not seem to be called sufficiently early to prevent the application framework from writing the HTTP headers.
HTTP Response Header Override
* Sets the HTTP headers required to indicate to the browser that the
* report is to be downloaded (rather than displayed in the current
* window).
protected void setDownloadHeaders() {
HttpServletResponse response = getServletResponse();
response.setHeader( "Content-Description", getContentDescription() );
response.setHeader( "Content-Disposition", "attachment, filename="
+ getFilename() );
response.setHeader( "Content-Type", getContentType() );
response.setHeader( "Content-Transfer-Encoding",
getContentTransferEncoding() );
Issue Response Complete
The bean indirectly tells the framework that the response is handled (by the bean):
getFacesContext().responseComplete();
Bean Run and Configure
public void run() {
try {
Report report = getReport();
configure(report.getParameters());
report.run();
} catch (Exception e) {
e.printStackTrace();
private void configure(Parameters p) {
p.put(ReportImpl.SYSTEM_REPORT_PROTOCOL, "http");
p.put(ReportImpl.SYSTEM_REPORT_HOST, "localhost");
p.put(ReportImpl.SYSTEM_REPORT_PORT, "7002");
p.put(ReportImpl.SYSTEM_REPORT_PATH, "/reports/rwservlet");
p.put(Parameters.PARAM_REPORT_FORMAT, "pdf");
p.put("report_cmdkey", getReportName());
p.put("report_ORACLE_1", getReportDestinationType());
p.put("report_ORACLE_2", getReportDestinationFormat());
Task Flow
The Task Flow calls Execute, which refers to the bean's `run()` method:
entry -> main -> Execute -> ReportBeanRun
Where:
<method-call id="ReportBeanRun">
<description>Executes a report</description>
<display-name>Execute Report</display-name>
<method>#{reportBean.run}</method>
<outcome>
<fixed-outcome>success</fixed-outcome>
</outcome>
</method-call>
The bean is assigned to the `request` scope, with a few managed properties:
<control-flow-rule id="__3">
<from-activity-id>main</from-activity-id>
<control-flow-case id="ExecuteReport">
<from-outcome>Execute</from-outcome>
<to-activity-id>ReportBeanRun</to-activity-id>
</control-flow-case>
</control-flow-rule>
<managed-bean id="ReportBean">
<description>Executes a report</description>
<display-name>ReportBean</display-name>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
The `<fixed-outcome>success</fixed-outcome>` strikes me as incorrect -- I don't want the method call to return to another task.
Restrictions
The report server receives requests from the web server exclusively. The report server URL cannot be used by browsers to download directly, for security reasons.
Error Messages
The error message that is generated:
Duplicate headers received from server
Error 349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION): Multiple distinct Content-Disposition headers received. This is disallowed to protect against HTTP response splitting attacks.Nevertheless, the report is being generated. Preventing the framework from writing the HTTP headers would resolve this issue.
Question
How can you set the HTTP headers in ADF while using a Task Flow to generate a PDF by calling a managed bean?
Ideas
Some additional ideas:
- Override the Page Lifecycle Phase Listener (`ADFPhaseListener` + `PageLifecycle`)
- Develop a custom Servlet on the web server

Thank you!

The problem was that the HTTP headers were in fact being written twice:
1. The report server was returning HTTP response headers.
2. The bean was including its own HTTP response headers (as shown in the question).
3. The bean was copying the entire contents of the report server response, including the headers, into the output stream.
Firefox ignored the duplicate header errors, but Google Chrome did not.

Encoding problem (Umlaute) in HTTP-Headers

Hi!
I have a servlet that is being called by another server via a POST request.
The request contains user data in HTTP-headers, and whenever there is a
German Umlaut in the user's name, it ends up garbled. :(
The requests character encoding is set to 'ISO-8859-1', according to the servlet
requests getCharacterEncoding() method.
I try to copy the value of a header variable into a String like this:
headerNameValue = request.getHeader("headerNameKey");Which, unfortunatly, doesn't work. For example, the value "G�nter" becomes "G��nter".
Shouldn't the API take care of the encoding, when the CharacterEncoding is set
right in the servlet call?
It looks like it interprets the ISO88591 data as Unicode?
BTW, I'm on a WebSphere 5 server, with Java 1.4.
I've been tearing my hair out on this one for days, so any help is highly appreciated.
Thanks a lot!
Andreas

A header variable with the key 'accept-charset' is not sent.
Only 'accept-encoding', with the value 'gzip, deflate'.
Like I wrote in my first post, the servlet request's character encoding is set to ISO-8859-1,
according to the getCharacterEncoding-method.
I have kind of solved this for now by converting the String 2times back, like this:
try {
     headerNameValue = new String((new String(headerNameValue.getBytes(),"UTF-8")).getBytes(),"UTF-8");
} catch (UnsupportedEncodingException e) {
      logger.error("Fehler beim Umwandeln der Umlaute im Benutzernamen.",e);
}                    }This code converts the '��', that my servlet receives, back to '�'.
(The first conversion changes the '��' to '��', the second the remaining '��' to '�').
While this seems to work, I don't think it is the right solution, and I still don't understand what's going on. :)

Andreas

HTTP headers vs HTTP URLs

Could someone please explain the very subtle difference between HTTP headers vs HTTP URLs?
Thanks.

Hi,
The URL is the resource location with or without additional parameters that will be requested - e.g. www.cisco.com or http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&needs_authentication=yes&forum=Data%20Center&
The HTTP headers on the other hand are additional parameters that are part of the HTTP protocol. They define things like Cookies, the referrer etc. A list of headers can be seen at http://en.wikipedia.org/wiki/List_of_HTTP_headers.
It is also possible to add your own headers - usually prefixed with X-.
If you look at the dissection of an HTTP conversation captured by Wireshark you'll see how the headers are used.

[WLS 10.3]:Weblogic.cache.filter does not cache all http headers

When using Weblogic CacheFilter servlet filter to speed our request. However, cached pages miss
some HTTP Headers ie: Content-Encoding.
As a result, if we setup a GZIP filter on most popular static text oriented document like css, html, js, the GZIP filter add a Content-Encoding http header set to gzip. But as CacheFilter forget that header, client receives the correct content-type but not anymore the Content-encoding.
Steps to Reproduce
Ask a static file like a .js library and sniff the HTTP headers. Switch the servlet filter order between gzip and CacheFilter, the HTTP header is correctly set but not when putting cache filter first.

Get http headers through GenericServlet

hi ,
Is it possible to get the http headers through the GenericServlet. I know i can get it through the HttpServlet. Considering that GenericServlet is parent class of HttpServlet I would think that is possible when I get the InputStream - request.getInputStream I should be able to print the headers too. But that does not seem to be happening ? Any information will be appreciated . thanks -sudhir

Greetings,
hi ,
Is it possible to get the http headers through the GenericServlet. I know i can get it through theTechnically, no. Message headers are intended to provide information to the container/encapsulating server relevant to its part in handling the request. Indeed, most headers are not even relevant to the servlet which provides only an "extension" of the server proper. The headers are available in an HttpServlet[Request] primarily because HttpServlets are intended to operate in place of their CGI counterparts (the CGI spec. converts nearly all headers into environment variables...) though not all headers are converted into accessor-enabled object members.
A GenericServlet, however, is, well, exactly that, "generic". It forms the basis of other protocol-specific implementations (which currently, to my knowledge, includes only HTTP...), and so making those "protocol specific" headers available to an implementation class is the responsibility of the "protocol specific" servlet container.
However, since you're (presumably) running your "generic servlet" in an HTTP-specific container environment, you can always try casting the ServletRequest object to an HttpServletRequest reference and call getHeader on it. ;)
HttpServlet. Considering that GenericServlet is parent class of HttpServlet I would think that is
possibleRefer again to the above.
when I get the InputStream - request.getInputStream I should be able to print the headers too. But
that does not seem to be happening ? Any information will be appreciated.Er, no. Input/output streams relate to the body (i.e. the content...) of the message. Headers relate to the meta-data of the message (i.e. its "envelope") - which, again, contains information relevant to the container. That information could be, for example, "routing instructions" - e.g. "Host" or "Referer" headers - or it could be, for example, "handling instructions" - e.g. "Accept-Encoding" or "Cookie" headers.
In the former case, the headers are mostly of relevance only to the container, though a servlet may also base some part of its processing on them and so they are made accessible through the getHeader method.
In the latter case, they are not necessarily relevant to either (the container or the servlet) though, when relevant, they are most likely relevant to the servlet - whether implicitly ("Accept-Encoding") or explicitly ("Cookie") - and so are made available either in the same "implicit" fashion (getHeader), or through a more "explicit" API call (getCookies).

Changing http headers using handlers

Is there anyway to access and set http headers using handlers? I took a look at the documentation and wasn't able to find a way to modify the http headers. Only SOAP related stuff. Need to go more low level.

Access the header by getting the HttpServletRequest object as follows:
handleRequest(MessageContext mc)
Object obj = mc.getProperty("weblogic.webservice.transport.http.request");
if(obj != null && obj instanceof javax.servlet.ServletRequest) {
request = (HttpServletRequest) obj;
request.getHeader("Name of Header");
That'll get you the request header.
I'd imagine you could do the same in a handleResponse method if what your trying to do is set a response header.

HTTP Headers - enabling caching and compression with the portal?

Has anyone configured their web server (IIS or Apache) or use a commercial product to flawlessly cache and compress all content generated by the portal?
Compression and caching is critical for making our portal based applictions work for overseas users. It should be doable, just taking advantage of standard HTTP protocols, but implementing this a complex system like the portal is tricky, we seem to be generating different values in the HTTP Headers for the same types of files (such as CSS).
We are running Apache so can't take advantage of the built in compression capabilities of the .net portal. We are running the java vervion. 6.1 mp1, sql server 2000 (portal, search, collab, publisher, studio, analytics, custom .net and java portlets on remote server).
Basically our strategy is to compress all outgoing static and dynamic text content (html, CSS, javascript), and to cache all static files (CSS, javascript, images) for 6 months to a year depending on file type.
Here are some links on the subjects of caching and compression that I have compiled:

Hi Scott,
Does Weblogic platform 8.1 supports netscape? We have developed a portal which
works perfectly on IE but it dies in netscape. Is netUI tags not supported in
Netscape?
Pls reply

Netscape 4.x and below have terrible performance with nested tables.
The
problem is not the Portal server but rather Netscape on the client machine.
If IE and/or a recent version of Netscape/Mozilla is not possible then
there are
really only two options:
1) Faster client hardware - not likely to be an acceptable solution.
2) Minimize the number of portlets and the complexity within the portlets.
Neither of these solutions are a great answer, but the 4.7 series of
Netscape is
getting pretty old. Having said that, we've got customers who want to
continue
to use IE 4 :)
Again, though, this problem is, I'm afraid out of our hands. It is the
client
rendering time that is the issue.

loading is that the headers will come up and when it gets to the bodyof the page
it seems to stall and then comes up all of a sudden. For some of thepages it
takes 6 seconds and for others it takes about 24-27 seconds.
We have suggested using IE only but that is not an option with allof the customers

Acrobat Reader X stores PDFs in Temp-folder even when HTTP-headers say no-cache no-store

After updating from Acrobat Reader 9 to 10 we have noticed that PDFs viewed in the browser are left behind in the Temp-folder even after the browser has been closed.
Http-headers in the response from the server
Cache-Controls: no-cache,no-store,max-age=0,post-check=0,pre-check=0
Content-Type: application/pdf
Content-Disposition: inline; filename="xxxxxxxx.pdf"
Expires: 0
Pragma: no-cache
Folder: [User-folder]\AppData\Local\Temp
Filename-format: PDFxxx.tmp
Browsers: Firefox 3.6, Opera 11, Safari 5
Plugin: Acrobat Reader 10
Simply add a .pdf extension to the file and open again in Acrobat Reader. Since the server has set headers indicating that this PDF should not be stored locally, it is a severe security hole leaving traces of this PDF on the filesystem.
Is this a problem Adobe is aware of? When can we expect this to be fixed?
Regards,
Gustav

Hi Michael,
Thank you for you quick response!
In Acrobat 9, I cannot find the PDFs in the Temp-folder after the browser has been closed.
In Acrobat 10, PDFs are left behind in the Temp-folder even after browser close.
To me, this looks like a bug in Acrobat 10. Would you not agree?

Gustav

Using custom http headers in SOAP sender adapter

Hi,
my problem is exactly the same as reported [here|Re: SOAP Sender - Extract Header Values;] and [here|Variable Transport Binding - Soap Sender;
Basically I'd like to send through the soap sender adapter some custom http headers. I check the necessary options in the advanced tab (set adapter-specific message attributes and variable transport binding), and in the variable header one I put x-StoreCode, which is the same http header I send to PI.
But I won't see anything in the dynamic configuration section when the message is persisted in PI.
Very surprised that I've seen this issue is a common problem others have faced before without success.
Thanks!

Hi Michal,
the extra info I'm trying to send separated from the message is an http header, not part of the query string.
If I incorporate the extra info as a parameter to the query string like this, for example:
http://host:50000/XISOAPAdapter/MessageServlet?senderParty=&senderService=S1&receiverParty=&receiverService=&interface=Int&interfaceNamespace=urn:test&x-StoreCode=13&nosoap=true
Then I can see the value in the dynamic configuration section:
<SAP:Record namespace="http://sap.com/xi/XI/System/SOAP" name="SQueryString">senderParty=&senderService=S1&receiverParty=&receiverService=&interface=Int&interfaceNamespace=urn:test&x-StoreCode=13&nosoap=true</SAP:Record>
But what I'm trying to do shoould be possible, according to sap help:
http://help.sap.com/saphelp_nwpi71/helpdata/en/fc/5ad93f130f9215e10000000a155106/content.htm (section Define Adapter-Specific Message Attributes)

Biztalk 2013 WCF-WebHTTP Adapter - Outbound HTTP Headers

Hi
I have a requirement to connect to a service using the WCF-WebHTTP adapter that requires authentication to be passed in the Headers.
A usercode and password is sent in the intial header and a security token is returned in the response header.
This security token is then used in the header of each subsequent call to the service.
I could not find anything in the documentation about getting and setting the "HTTP Header" data using maps or variables or using variables in the "Outbound HTTP Headers" on the adapter transport properties.
Any help on this would be gratefully received.
Malcolm

You can set the outbound HTTP header in WCF-WebHTTP adapter by 2 ways
1) At adapter level Change adapter properties
2)Changing Message context property at Orchestration or at pipeline
Its been well documented here

SAXBuilder builder = new SAXBuilder(); //==<< get reponse
Document doc = builder.build(theSock.getInputStream());
.at builder.build I've got "SAXException: Parsing Error : The root element is required in a well-formed document" .
that because output from theSock.getInputStream() is
HTTP/1.1 200 OK
Date: Wed, 04 Jul 2007 10:14:54 GMT
Content-Length: 105
Content-Type: text/xml;charset=UTF-8
Connection: close
<resp>
<status>200</status>
<description>ok</description>
</resp>I know that if i use HttpURLConnection the response InputStream will not contain http headers. But I'm just curious that with Socket, Is there any trick to get only content from InputStream?

There is no trick except to use the HttpUrlConnection class. That�s why it was created. It wraps the socket and parses through the headers for you. The socket is very low level and all it sees are bits over an input stream (TCP / UDP). It does not know or care about HTTP which is a protocol on top of TCP.

Http header setting in servlet

Hello,
I want to set the header parameters of http response in my servlet.
I set parameters as below:
          theResponse.setHeader("Request Version", "HTTP/1.1");
          theResponse.setStatus(200);
          theResponse.setHeader("Date", "Wed, 18 Apr 2007 09:24:04 GMT");
          theResponse.setHeader("Server", "Tomcat");
          theResponse.addCookie(theRequest.getCookies()[0]);
          theResponse.setHeader("pragma", "no-cache"); // HTTP 1.0
          theResponse.setHeader("Cache-Control", "no-cache"); // HTTP 1.1
          theResponse.setHeader("Expires", "Mon, 26 Jul 1997 05:00:00 GMT"); // a past date
          theResponse.setDateHeader("Last-Modified", (new java.util.Date()).getTime());
          theResponse.setHeader("Connection", "close");
          theResponse.setContentType("text/plain");
//some other things...
          PrintWriter aPrintWriter = theResponse.getWriter();
          aPrintWriter.write("this is the string to be put into the body part of the http packet.");
However, I am checking what I am sending as response using the ethereal network sniffing tool and seeing the result below:
HTTP/1.1 200 OK\r\n
Request Version: HTTP/1.1
Response Code: 200
Server: Apache-Coyote/1.1\r\n
Content-Length: 68\r\n
Date: Tue, 24 Apr 2007 17:55:10 GMT\r\n
\r\n
Data (68 bytes)
I am setting header parameters as it should be.. But it doesn't care about my parameters and Tomcat puts some values that it selects..
Where is my fault? Can anyone recommend sth please..? I am really stucked here..
Thanks & Regards

Hello,
It looks like your question is really related to Tomcat (coyote). However if you want to control the server name on OC4J you can do it, see this blog entry:

Firefox is trying to send strange multiple requests on port 7070. As I allow the request nothing appears in "http headers" addon window. What could this be?

Hi.
I discovered my Firefox v26 was SOMETIMES trying to send multiple requests on port 7070 (ukrainian ip-address) independently on what websites were opened at the moment.
The problem remains after v27 update.
I have an addon "live http headers" installed.
As I manually allow the request by firewall nothing appears in the headers window.
Does my firefox seem to be modified with adware/spyware?
