  • Why does HP Update at remote system trigger RDP printing at local system?

    - by lcbrevard
    This is obscure. When connected with RDP to another system that has HP Update installed on it, either directly running the HP Update or having the notification pop up to ask if you want to run HP Update causes the local system to try to print something to peculiarly-chosen-local-printer. Case 1: Desktop Win 7 Ult system RDP connected to HP Laptop Win 7 Ult system. When HP Update runs on the laptop a dialog for XPS Writer Save As... appears on Desktop system. Even if you put in a name, nothing gets generated and the dialog repeats. And repeats. Until you (a) close the RDP connection and (b) clean out the queued entries. If the HP Update pops up the request to run the update and you are not at the desk when this happens, there can be dozens of queued requests for this bogus printing. NOTE: the XPS Writer is not selected as a default printer on either system. Case 2: (Different) HP Laptop Win 7 Ult system RDP connected to XP Pro "brand X" desktop system but with HP printer drivers installed. If the request to run HP Update notification pops on the XP system, dozens of attempts to print, in this case to a Versa Check Printer driver, are queued. Dismissing the HP request, closing RDP, and cleaning out the queue are required to stop this. NOTE: the Versa Check Writer is not selected as a default printer on either system. THE QUESTION: What the heck is going on here? Some kind of scripting or COM activity that is misdirected?

  • printing in linux

    - by Neilvert Noval
    Hello all. I've been a linux user for quite some time. But haven't do printing until now. I just wanna ask how to do printing in linux? I have researched a bit on it. I found some $> echo "print me" > /dev/lp0, but unfortunately, I have no lp0 in my /dev. I don't know if this is the right thing to do. Nevertheless, please tell me of ways on how I can print from my linux box. Here are some details: OS: debian linux 5.0.4 printer: disclosed until it is necessary connection: usb connection So do i need to add a printer first? From the printer manual that I read, this printer model has no linux driver.

  • Enabling "USB Printing Support" in Windows 7

    - by Kevin Dente
    I'm trying to use an old parallel-port based printer with a USB-to-parallel port adapter on Windows 7. When I plug it into the USB port on the computer it's listed as an unrecognized device. I know that these cables typically use the "USB Printing Support" driver with makes USB ports show up as printer ports in the printer dialog. Is there a way to manually add USB Printing Support to Windows 7, since it isn't being added automatically?

  • Is there a (free or commercial) print server which print PDFs from networks?

    - by Eonil
    I'm working in office which uses Windows server for printing. Because our printer supports only Windows driver. But here are Mac OS X also which requires network printing... I'm sure there is no driver of the printer for Mac. So I figured out an idea to do this. On the Mac, a virtual printer driver generates and sends PDF file to print server. Print server, prints PDF files with it's local printer. Is there a solution can do this? (free or commercial)

  • Software disables itself when the PC is accessed via RDP

    - by blckgrffn
    We have a large, specialty printer that has vendor specific software that enables its use outside of it showing up simply as a printer in the Windows Control Panel. This software recognizes when we RDP into the machine and "disconnects" the PC from the printer within its proprietary control panel. All is well when an application like TeamViewer is used to access the machine. Ostensibly, the application is helping us be safe by "enforcing" that the machine used for the printer is a walk up workstation, or so the support folks informed me. If TeamViewer etc, fixes the issue, then what is the problem? We have many headless workstations in our warehouse attached to a variety of specialty machines, all used via RDP. We want/need to keep access to the machines the same for the sanity of our production staff. The meat of the question - how, specifically, might a machine know that it is being accessed via RDP (terminal services management???) and how might this be defeated without altering an application or driver. Of note, the system being used is a Windows 7 Pro machine hooked to the printer via USB. Thanks! Nat edit Is there any combination of /admin switches, etc. that will possibly fix this? Simply putting /admin did not.

  • Dual LAN Printing

    - by Christopher
    I want to use Ubuntu 10.10 Server in a classroom, a computer lab whose bandwidth is provided by a local cable ISP. That's no problem, though the school network has an IP printer that I want to use. I cannot reach the printer through the cable Internet. But, I have two network cards. How is it possible to use both networks at once? eth0 (static 192.168.1.254) is plugged into a four-port router, 192.168.1.1. On the public side of the four-port router is Internet provided by the cable company. I also have the classroom workstations plugged into a switch. The switch is plugged into the four-port router. The whole classroom is wired into the cable Internet. The other NIC, eth1, could it be plugged into an Ethernet jack in the wall? It uses the school network, and I might receive by DHCP an IP address like 10.140.10.100, with the printer on maybe 10.120.50.10. I was thinking about installing the printer on the server so that it could be shared with the workstations. But how does this work? Can I just plug eth1 into the school network and access both LANs? Thanks for any insight, Chris

  • Brother MFC-J470DW scan function "Check Connection"

    - by user292599
    I have a Brother MFC-J470DW printer that I have connected to a Linux desktop (running Ubuntu 14.04) using a wireless router network. The printer works fine for printing and copying, but now I want to add the scan function. To set up the scan function, I went to the Brother web page for this printer: http://support.brother.com/g/b/downloadlist.aspx?c=eu_ot&lang=en&prod=mfcj470dw_us_eu_as&os=128 and under Scanner Drivers selected "Scanner driver 64bit (deb package)", "Scan-key-tool 64bit (deb package)", and "Scanner Setting file (deb package)". For each package, I clicked the EULA, and selected "open with Ubuntu Software Center". Then after the USC window pops up, I click on Install and the red line goes from left to right. In each case, the USC window then had a green checkmark and the Install box changes to Reinstall (that's how you know it worked). So now I try it out. Hitting the Scan button on the printer, selecting "Scan to file", and hitting ok produces the message "Check Connection". I checked the Brother Linux Information FAQ (scanner) page and the 14th question seems the same as mine: When I try to use the scan key on my network connected machine, I receive the error "Check connection" or I can not select anything except "scan to FTP". I explored the solution given for this FAQ, but found from ifconfig that I am already using eth0, the default setting, so presumably that is not the problem. I also found brscan-skey installed in /usr/bin and did drrm@drrmlinux2:~$ brscan-skey -t drrm@drrmlinux2:~$ brscan-skey but that didn't help - I still get the "Check connection" message. What can you suggest to fix this problem?

  • Explicitly instantiating a generic member function of a generic structure

    - by Dennis Zickefoose
    I have a structure with a template parameter, Stream. Within that structure, there is a function with its own template parameter, Type. If I try to force a specific instance of the function to be generated and called, it works fine, if I am in a context where the exact type of the structure is known. If not, I get a compile error. This feels like a situation where I'm missing a typename, but there are no nested types. I suspect I'm missing something fundamental, but I've been staring at this code for so long all I see are redheads, and frankly writing code that uses templates has never been my forte. The following is the simplest example I could come up with that illustrates the issue. #include <iostream> template<typename Stream> struct Printer { Stream& str; Printer(Stream& str_) : str(str_) { } template<typename Type> Stream& Exec(const Type& t) { return str << t << std::endl; } }; template<typename Stream, typename Type> void Test1(Stream& str, const Type& t) { Printer<Stream> out = Printer<Stream>(str); /****** vvv This is the line the compiler doesn't like vvv ******/ out.Exec<bool>(t); /****** ^^^ That is the line the compiler doesn't like ^^^ ******/ } template<typename Type> void Test2(const Type& t) { Printer<std::ostream> out = Printer<std::ostream>(std::cout); out.Exec<bool>(t); } template<typename Stream, typename Type> void Test3(Stream& str, const Type& t) { Printer<Stream> out = Printer<Stream>(str); out.Exec(t); } int main() { Test2(5); Test3(std::cout, 5); return 0; } As it is written, gcc-4.4 gives the following: test.cpp: In function 'void Test1(Stream&, const Type&)': test.cpp:22: error: expected primary-expression before 'bool' test.cpp:22: error: expected ';' before 'bool' Test2 and Test3 both compile cleanly, and if I comment out Test1 the program executes, and I get "1 5" as I expect. So it looks like there's nothing wrong with the idea of what I want to do, but I've botched something in the implementation. If anybody could shed some light on what I'm overlooking, it would be greatly appreciated.

  • How to pretend to be a Printer on iOS like the Apps Save2PDF or Adobe® CreatePDF?

    - by Lindemann
    I want to convert HTML to PDF on an iOS Device... ...but I dont want to load my HTML in a UIWebView, take a snapshot and generate an ugly PDF from this snapshot picture...because the text must be selectable for my purpose. I wonder how Apps like Save2PDF or Adobe® CreatePDF are able to converting multiple files into PDF and save them. I guess they don't generate the PDF's by their own, but get them from Apples Printing Framework. How does this Apps work?

  • streaming xml pretty printer in C/C++ using expat or libxml2?

    - by Mark Zeren
    I have a library that outputs xml without whitespace all on one line. In some cases I'd like to pretty print that output. I'm looking for a BSD-ish licensed C/C++ library or sample code that will take a raw xml byte stream and pretty print it. Here's some pseudo code showing one way that I might use this functionality: void my_write(const char* buf, int len); PrettyPrinter pp(bind(&my_write)); while (...) { // ... get some more xml ... const char* buf = xmlSource.get_buf(); int len = xmlSource.get_buf_len(); int written = pp.write(buf, len); // calls my_write with pretty printed xml // ... error handling, maybe call write again, etc. ... } I'd like to avoid instantiating a DOM representation. I already have dependencies on the expat and libxml2 shared libraries, and I'd rather not add any more shared library dependencies.

  • Complete Guide to Networking Windows 7 with XP and Vista

    - by Mysticgeek
    Since there are three versions of Windows out in the field these days, chances are you need to share data between them. Today we show how to get each version to be share files and printers with one another. In a perfect world, getting your computers with different Microsoft operating systems to network would be as easy as clicking a button. With the Windows 7 Homegroup feature, it’s almost that easy. However, getting all three of them to communicate with each other can be a bit of a challenge. Today we’ve put together a guide that will help you share files and printers in whatever scenario of the three versions you might encounter on your home network. Sharing Between Windows 7 and XP The most common scenario you’re probably going to run into is sharing between Windows 7 and XP.  Essentially you’ll want to make sure both machines are part of the same workgroup, set up the correct sharing settings, and making sure network discovery is enabled on Windows 7. The biggest problem you may run into is finding the correct printer drivers for both versions of Windows. Share Files and Printers Between Windows 7 & XP  Map a Network Drive Another method of sharing data between XP and Windows 7 is mapping a network drive. If you don’t need to share a printer and only want to share a drive, then you can just map an XP drive to Windows 7. Although it might sound complicated, the process is not bad. The trickiest part is making sure you add the appropriate local user. This will allow you to share the contents of an XP drive to your Windows 7 computer. Map a Network Drive from XP to Windows 7 Sharing between Vista and Windows 7 Another scenario you might run into is having to share files and printers between a Vista and Windows 7 machine. The process is a bit easier than sharing between XP and Windows 7, but takes a bit of work. The Homegroup feature isn’t compatible with Vista, so we need to go through a few different steps. Depending on what your printer is, sharing it should be easier as Vista and Windows 7 do a much better job of automatically locating the drivers. How to Share Files and Printers Between Windows 7 and Vista Sharing between Vista and XP When Windows Vista came out, hardware requirements were intensive, drivers weren’t ready, and sharing between them was complicated due to the new Vista structure. The sharing process is pretty straight-forward if you’re not using password protection…as you just need to drop what you want to share into the Vista Public folder. On the other hand, sharing with password protection becomes a bit more difficult. Basically you need to add a user and set up sharing on the XP machine. But once again, we have a complete tutorial for that situation. Share Files and Folders Between Vista and XP Machines Sharing Between Windows 7 with Homegroup If you have one or more Windows 7 machine, sharing files and devices becomes extremely easy with the Homegroup feature. It’s as simple as creating a Homegroup on on machine then joining the other to it. It allows you to stream media, control what data is shared, and can also be password protected. If you don’t want to make your Windows 7 machines part of the same Homegroup, you can still share files through the Public Folder, and setup a printer to be shared as well.   Use the Homegroup Feature in Windows 7 to Share Printers and Files Create a Homegroup & Join a New Computer To It Change which Files are Shared in a Homegroup Windows Home Server If you want an ultimate setup that creates a centralized location to share files between all systems on your home network, regardless of the operating system, then set up a Windows Home Server. It allows you to centralize your important documents and digital media files on one box and provides easy access to data and the ability to stream media to other machines on your network. Not only that, but it provides easy backup of all your machines to the server, in case disaster strikes. How to Install and Setup Windows Home Server How to Manage Shared Folders on Windows Home Server Conclusion The biggest annoyance is dealing with printers that have a different set of drivers for each OS. There is no real easy way to solve this problem. Our best advice is to try to connect it to one machine, and if the drivers won’t work, hook it up to the other computer and see if that works. Each printer manufacturer is different, and Windows doesn’t always automatically install the correct drivers for the device. We hope this guide helps you share your data between whichever Microsoft OS scenario you might run into!

  • Print to File in Black and White (not in greyscale)

    - by user2413
    Hi all, I have these pdf files of c++code and they are colored which would be cool, except that the network printer here is b&w and the printed out codes come in various shades of pale grey which makes them essentially unreadable (specially the comments). I would like everything (text, codes, commands,...) to be printed in the same (black) color. i've tried fuddling with the printer's properties, but the closest thing i see is the 'level of grey' tab, and there i have the choice between 'enhanced' and 'normal' (and it doesn't make a difference in my case). i've tried 'print to file', but i don't see any options there to print to b&w, I've tried installing the 'generic cups printer', but again no options to print to b&w. any idea ? (i'm on 10.10)

  • 12.04 scanner works fine as super-user but is not recognised as a normal user

    - by Eugénio Outeiro
    I have an all-in-one printer Epson SX130, wich I have just tried to install. I got the printer working with no problem, but I couldn't set the scanner up. I have had another all-in-one printer before (Brother DCP-125C), and had just the same problem, so I decided to try the same trick I used to do then, running the scanning program as super-user: $sudo simple-scan and $ sudo xsane Once again, it worked just fine, and I could use the scanner. Anyhow, this solution is a little annoying, because I also have to change the permissions to the files I get scanning like this. I have been searching the internet for solutions and got to know this must have something to do with user groups permissions, but couldn't find a satisfying solution. Is there anyone with an idea? Thank you in advance.

  • Lexmark X7170 shows documents as printed when they haven't

    - by Mehmet
    I made the move from Windows 7 to Ubuntu not dual booting because I have decided to quit gaming to spare more time for my studies. I just needed an OS for browsing the web and word processing etc. After I installed Ubuntu I installed the AMD GPU drivers, after which I clicked on the little printer icon, selected add printer and it found the drivers for the Lexmark 7000 series and I installed them. Now my problem is when I print something from Writer it processes it thinks its completed it, when in fact it hasn't printed anything. I tried printing a test page but it was stuck on processing for 5 minutes. I have restarted my computer and turned the printer on and off. I'm running 64bit if that changes anything.

  • Print Problem: Page Squeezed in Half

    - by iam
    I've just managed to successfully set up my printer (Canon MX320) using the Printing app on Ubuntu 12.04. However the only 1 remaining problem is that each time I tried to print it will only print the file on the top half of the page only: meaning that for some reason, the printer "squeezes" the whole content of each page in the file to fit into the top half of the page only (so the proportion in the print-out is not correct vertically). This happens with every type of file I tried to print (Documents, Images, Web pages). I checked the Printing's setting & properties and couldn't find anything related to this issue yet and I've already made sure to set all the information correct (paper size, source etc.). The Print Preview always display correctly on the screen, but it's only the actual print-out that shows this problem. I also tried with several different types of papers (A4, photos etc.) but the result is always the same: the printer keeps putting the content in the top half of the paper only.

  • networkprinting with cups in ubuntu 13.10

    - by gero
    I upgraded from Ubuntu 13.04 to Ubuntu 13.10. The printer configurations were transferred correctly. I have an USB laser printer, which still works if I connect my laptop directly. Usually I used this printer by wlan or bluetooth, where an old laptop works as server (cups 1.3.X). If I now want to print some pdf or postscript file, one or the other way I only obtain a header printed, not the content of the file. Curiously the Ubuntu 13.10 test page is printed correctly.

  • Dell b1160w not working in 14.04

    - by mission007
    I originally installed the dell b1160w printer on ubuntu 12.04. It worked as expected. A few months ago I upgraded to ubuntu 14.04 and now I can't get the printer to work. I looked at the driver information on the dell site. They have not updated their driver since 2013 so 12.04 is the latest version with a supported driver. Is there a work around for this problem, like a generic driver that I can use or a way to install whatever printer interface ubuntu 12.04 was using? I have a windows virtual box. I can get it to work through there, but it's inconvenient to pull up my virtual box and transfer the files over to it anytime I want to print.

  • WCF fails to deserialize correct(?) response message security headers (Security header is empty)

    I'm communicating with an OC4J webservice, using a WCF client. The client is configured as follows: <basicHttpBinding> <binding name="MyBinding"> <security mode="TransportWithMessageCredential"> <transport clientCredentialType="None" proxyCredentialType="None" realm=""/> <message clientCredentialType="UserName" algorithmSuite="Default"/> </security> </binding> My clientcode looks as follows: ServicePointManager.CertificatePolicy = new AcceptAllCertificatePolicy(); string username = ConfigurationManager.AppSettings["user"]; string password = ConfigurationManager.AppSettings["pass"]; // client instance maken WebserviceClient client = new WebserviceClient(); client.Endpoint.Binding = new BasicHttpBinding("MyBinding"); // credentials toevoegen client.ClientCredentials.UserName.UserName = username; client.ClientCredentials.UserName.Password = password; //uitvoeren request var response = client.Ping(); I've altered the CertificatePolicy to accept all certificates, because I need to insert Charles (ssl proxy) in between client and server to intercept the actual Xml that is sent across te wire. My request looks as follows: <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <s:Header> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <u:Timestamp u:Id="_0"> <u:Created>2010-04-01T09:47:01.161Z</u:Created> <u:Expires>2010-04-01T09:52:01.161Z</u:Expires> </u:Timestamp> <o:UsernameToken u:Id="uuid-9b39760f-d504-4e53-908d-6125a1827aea-21"> <o:Username>user</o:Username> <o:Password o:Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username- token-profile-1.0#PasswordText">pass</o:Password> </o:UsernameToken> </o:Security> </s:Header> <s:Body> <getPrdStatus xmlns="http://mynamespace.org/wsdl"> <request xmlns="" xmlns:a="http://mynamespace.org/wsdl" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> <a:IsgrStsRequestTypeUser> <a:prdCode>LEPTO</a:prdCode> <a:sequenceNumber i:nil="true" /> <a:productionType i:nil="true" /> <a:statusDate>2010-04-01T11:47:01.1617641+02:00</a:statusDate> <a:ubn>123456</a:ubn> <a:animalSpeciesCode>RU</a:animalSpeciesCode> </a:IsgrStsRequestTypeUser> </request> </getPrdStatus> </s:Body> </s:Envelope> In return, I receive the following response: <env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns0="http://mynamespace.org/wsdl"> <env:Header> <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" env:mustUnderstand="1" /> </env:Header> <env:Body> <ns0:getPrdStatusResponse> <result> <ns0:IsgrStsResponseTypeUser> <ns0:prdCode>LEPTO</ns0:prdCode> <ns0:color>green</ns0:color> <ns0:stsCode>LEP1</ns0:stsCode> <ns0:sequenceNumber xsi:nil="1" /> <ns0:productionType xsi:nil="1" /> <ns0:IAndRCode>00</ns0:IAndRCode> <ns0:statusDate>2010-04-01T00:00:00.000+02:00</ns0:statusDate> <ns0:description>Gecertificeerd vrij</ns0:description> <ns0:ubn>123456</ns0:ubn> <ns0:animalSpeciesCode>RU</ns0:animalSpeciesCode> <ns0:name>gecertificeerd vrij</ns0:name> <ns0:ranking>17</ns0:ranking> </ns0:IsgrStsResponseTypeUser> </result> </ns0:getPrdStatusResponse> </env:Body> </env:Envelope> Why can't WCF deserialize this response header?

I've already tried Rick Strahl's suggestion and removed the timestamp from the request header. Any help greatly appreciated!

  • Convert XML namespace prefixes with C#?

    - by jrista
    I have run into an exasperating problem getting a Java service client to communicate successfully with a WCF service. I have overcome many hurdles, and I believe that this is my last one. The problem boils down to how Java Axis + WSS4J seem to handle xml namespaces. The Java platform seem to be very rigid in what they expect for xml namespace prefixes, and as such, do not understand the WCF reply messages. My problem in a nutshell is as follows. I have an xml response similar to the following from my WCF service: <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <s:Header> <a:Action s:mustUnderstand="1" u:Id="_3">http://tempuri.org/IProcessor/DoProcessingResponse</a:Action> <h:CorrelationID xmlns:h="http://tempuri.org/">1234</h:CorrelationID> <a:RelatesTo u:Id="_4">uuid:40f800a0-9613-4f4a-96c5-b9fd98085deb</a:RelatesTo> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <!-- WS-Security header stuff --> </o:Security> </s:Header> <s:Body u:Id="_1"> <e:EncryptedData Id="_2" Type="http://www.w3.org/2001/04/xmlenc#Content" xmlns:e="http://www.w3.org/2001/04/xmlenc#"> <e:EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#aes128-cbc"/> <e:CipherData> <e:CipherValue>NfA6XunmyLlT2ucA+5QneoawHm+imcaCltDAJC1mRZOSxoB6YGpDLY1FyVykPbPGDoFGUESLsmvvbD62sNnRrgE+AuKPo+1CD3DF4LfurRcEv9A50ba9V+ViqlrhydhK</e:CipherValue> </e:CipherData> </e:EncryptedData> </s:Body> </s:Envelope> This response uses simple one-character namespace prefixes for most things, such as 's' for SOAP Envelope, 'a' for WS-Addressing, 'o' for 'WS-Security', etc. The Java client, namely WSS4J, seems to expect the following: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsa="http://www.w3.org/2005/08/addressing" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <soap:Header> <wsa:Action soap:mustUnderstand="1" wsu:Id="_3">http://tempuri.org/IProcessor/DoProcessingResponse</wsa:Action> <h:CorrelationID xmlns:h="http://tempuri.org/">1234</h:CorrelationID> <wsa:RelatesTo wsu:Id="_4">uuid:40f800a0-9613-4f4a-96c5-b9fd98085deb</a:RelatesTo> <wsse:Security soap:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <!-- WS-Security header stuff --> </wsse:Security> </soap:Header> <soap:Body u:Id="_1"> <xenc:EncryptedData Id="_2" Type="http://www.w3.org/2001/04/xmlenc#Content" xmlns:xenc="http://www.w3.org/2001/04/xmlenc#"> <xenc:EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#aes128-cbc"/> <xenc:CipherData> <xenc:CipherValue>NfA6XunmyLlT2ucA+5QneoawHm+imcaCltDAJC1mRZOSxoB6YGpDLY1FyVykPbPGDoFGUESLsmvvbD62sNnRrgE+AuKPo+1CD3DF4LfurRcEv9A50ba9V+ViqlrhydhK</xenc:CipherValue> </xenc:CipherData> </xenc:EncryptedData> </soap:Body> </soap:Envelope> Upon receipt of my response message, the Java client and WSS4J seem to want to look up elements by their own internal xml aliases, such as 'wsa' for WS-Addressing, and 'wsse' for WS-Security Extensions. Since neither of those namespaces are present in the actual response xml, exceptions are thrown. I am wondering if there is any simple way to transform an xml document from one set of namespaces to another set using C#, .NET, and the System.Xml namespace. I've poked around with XmlNamespaceManager a bit, but it does not seem to fully support what I need...or at least, I have been unable to find any really useful examples, and am not fully sure how it works. I am trying to avoid having to write some heavy-duty process to handle this manually myself, as I do not want to drastically impact the performance of our services when called by a Java Axis/WSS4J client.
