Modify HTTP Headers with FileServlet?

When I use netscape as a webserver, we can specify HTTP headers that go out
on all the static content to insure that it is cached on the client for at
least a few minutes...
Does anyone know how to do that with WLS?
The exact header:
Cache-control: max-age=36000
this is the context:
HTTP/1.1 200 OK
Server: Netscape-Enterprise/4.1
Date: Mon, 10 Sep 2001 23:46:53 GMT
Cache-control: max-age=36000
Content-type: image/gif
Etag: "c1153a1a-1098-2b-3b9933f8"
Last-modified: Fri, 07 Sep 2001 20:54:16 GMT
Content-length: 43
Accept-ranges: bytes
This is how we get it in netscape:
<Object ppath="/usr/netscape/server4/docs/sqa/images/*">
PathCheck fn="set-cache-control" control="max-age=36000"
</Object>

you can access the SOAP headers in the call, but I don't think the HTTP headers are directly available.

Accessing Java webservice (XML over http) via WCF or HTTP adapter with content-type and authorization HTTP headers with POST method

Hi Team,
I need to access Java web service which is simple service and accepts and returns XML over HTTP. No credentials are needed to access the service. We need to pass following two HTTP headers (Content-Type and Authorization) along with XML request message:
<GetStatus> message is being constructed in the orchestration and URI is constant to access.
Which adapter shall I use to get the response back? I tried using WCF-WSHttp with Security Mode = Transport, and different options of client credential types but every time, error returned stating:
System.Net.WebException:
The HTTP request is unauthorized with client authentication scheme 'Basic'. The
authentication header received from the server was 'Basic realm='.
Authentication failed for principal Basic. Message payload is of type:
String
In Fiddler, request looks line following
POST <https://URL/GetServiceReopnse HTTP/1.1
Content-Type: application/xml
Authorization: Basic cmVmU3RhdHN2Y19kgeRfsdfs=
Host: <Server name>
<GetStatus XMLNS="http://server.com/.....">
<OrgId>232323</OrgId>
<HubId>3232342323</HubId>
</GetStatus>

First, you should not use the HTTP Adapter because it's been deprecated and replaced by WCF.
Start with the WCF-Custom Adapter and select the customBinding.
You should start with the textMessageEncoder and httpTransport and go from there.

Invoke stateful ws: Can't get HTTP headers with CustomHeaderHandler

Hello,
I am trying to invoke a stateful ws as described here (http://www.oracle.com/technetwork/middleware/ias/callingstatefulwsfrombpel-091022.html).
I can succesfully send custom http headers declaring a CustomHeaderHandler.
However, when I try to access the data on the response I cannot get the headers. Hence, I can't get the session ID to pass around. According to what I've seen it should be in the pCallProps variable from the inovke method on the Handler. However that only has: pCallProps [tracking.compositeInstanceId, tracking.conversationId] as keys.
I'm working on soa version 11g.
Any input is appreciated. If I need to expand information, please ask and I will.
Thanks in advance!

Not sure this will help, but here goes:
I looked through your stack trace for a phrase that is relatively unique and summarizes the problem. I then google searched on it.
Here is what I googled on:
com.mysql.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java
I found this that might be of help:
http://dev.mysql.com/doc/refman/4.1/en/connector-j-usagenotes-troubleshooting.html#qandaitem-19-4-5-3-7
In that document I found this:
"The error probably indicates that you are using a older version of the Connector/J JDBC driver (2.0.14 or 3.0.x) and you are trying to connect to a MySQL server with version 4.1x or newer. The older drivers are not compatible with 4.1 or newer of MySQL as they do not support the newer authentication mechanisms.
It is likely that the older version of the Connector/J driver exists within your application directory or your CLASSPATH includes the older Connector/J package.
Also, the word 'NonRegisteringDriver' above indicates your JDBC (which is a driver_ is a non registering type.
I suggest you hit the MySql home page and see if you can download a newer driver.

Custom Headers with LrHttp.post?

I am using custom HTTP headers in my application and this works
great with LrHttp.get. However, LR doesn't send anything when I try to do this with LrHttp.post.
My code looks like the following:
            local customHdrs = {
                { field="XXX", value="yyy" }
            local data, hdrs = LrHttp.get(url, customHdrs)
            data, hdrs = LrHttp.post(url, xxx, customHdrs)
Any ideas? Has anyone used custom HTTP headers with post before?
Thanks!

Hi,
I've used standard headers with LrHttp.postMultipart, but not custom headers with LrHttp.post. Could you try using LrHttp.postMultipart instead to see if it has any more luck for you than LrHttp.post?
Also have you tried using something like Fiddler2 to intercept the HTTP traffic and confirm whether or not the headers were sent with the request?

Cisco CSS - modify http header

hi, i need to modify http hearder with the client IP address. need to modify any of the folowing fields:
1) FROM -> with client IP address
CLIENT IP -> with Client IP address
2) X-Forwarded-For -> with client IP address
3) REMOTE_ADDR -> with client IP address
please advise how do to modify http header with option 1 or 2 or 3.
Thanks.

Hi Gavin
I think I misread your question.
Question first. Is your CSS configured with one arm and doing client source natting and the server needs to see the real ip address of the client? Is that the reason why you want to insert x-forward-for header with the clients real IP address?
I did some search with CSS but the CSS doesn't seem to support this feature.
If you need to see the actual client ip address from the server, then you can do pbr from the router rather than client source natting.

I have installed Modify headers with Mozilla, but do I add the Android emulators?

I have installed Modify headers with Mozilla, but I can not find any information on how to add the emulated Android devices. I want to be able to view the websites as they are seen by the Android devices. That is why I want to add the emulated Android devices to Modify headers.

See if the Modify Headers developer's Help page answers your question. <br />

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.

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

From a pure HTML perspective Portal does it's rendering with nested

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.

b/c it takes so long to load some of the webapps. What the pages willdo when
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
and getting a newer version of Netscape is also out of the question.
Any suggestions would be greatly appreciated.--

Hi all!
Just to post the solution to this if anyone ever runs accross this thread...
For some reason i had it bad the first time, don't have time right now to see why but here is what worked for me:
HashMap primaryFile = new HashMap();
primaryFile.put("fileContent", bFile);
primaryFile.put("fileName", uploadedFile.getFilename());
operationBinding.getParamsMap().put("primaryFile", primaryFile);
HashMap customDocMetadata = new HashMap();
HashMap [] properties = new HashMap[1];
HashMap customMetadataPropertyRoom = new HashMap();
customMetadataPropertyRoom.put("name", "xRoom");
customMetadataPropertyRoom.put("value", "SOME ROOM");
properties[0] = customMetadataPropertyRoom;
customDocMetadata.put("property", properties);
operationBinding.getParamsMap().put("CustomDocMetaData", customDocMetadata);
Basically an unbounded wsdl type is an array of objects (HashMaps), makes sense, i thought i had it like this before, must have messed up somewhere...
Good luck all!

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?

Hi again,
this may be old news to some people, but I just realized we can have the desired benefits I originally listed (encapsulation, reuse, maintainability, security) TODAY by using pipelined functions and using the table() function in Apex report region queries.
So the report query basically becomes, for example (if get_employees is a pipelined function)
select * from table(my_package.get_employees(:p1_deptno))
The only downside compared to a (weakly typed) sys_refcursor is that you have to define the type you are returning in your package spec (or as an SQL type). So it's a bit more coding, but it's still worth it for the other benefits it provides.
I like Apex even better now! :-)

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. :)
Regards,
Andreas

Web service response contains SOAP Headers with "mustUnderstand" true

Hi
I have a requirement where in I have to consume a web service as adaptive web service model, and while executing the service pass a mandatory parameter to the soap header. We are able to set the mandatory parameter to the soad header. We got the code snippet to do this from a wiki link
http://wiki.sdn.sap.com/wiki/display/WDJava/FAQ-Models-AdaptiveWebService#FAQ-Models-AdaptiveWebService-WhatarethefunctionalgapsofthecurrentAdpativeWSModelImporter%3F
On executing the service now through web dynpro we are getting the below error
"Web service response contains SOAP Headers with "mustUnderstand" true which are not handled by the client runtime"
Any thoughts on how to handle this mustUnderstand attribute with some code snippet? Appreciate all help.
Thanks,
KN.

Hi
Have you found the workaround?
Sorry for refreshing topic. Flag mustUnderstand ='1' in response is unussual thing.
