hai

Hi Sravan,
Import this package in your login view
com.sap.tc.webdynpro.progmodel.controller.MessageManager;
And if your context attributes are Name and Password.And if you are navigating from LoginView to HomeView. Write the code given below inside your action event.
String login=wdContext.currentContextElement().getName();
String password=wdContext.currentContextElement().getPassword();
     if(login!=null && login.equalsIgnoreCase("XXX") && password!=null && password.equalsIgnoreCase("YYY"))
          wdThis.wdFirePlugToHomeView();
     else
MessageManager msgMgr= (MessageManager) wdThis.wdGetAPI().getComponent().getMessageManager();
msgMgr.reportException("Login failure.Pls check login details",true);
Hope this will help you

  • How to pass username and password with the portal url

    i want to access portal from my web site. i have created username and password fields in my web page. when submited , my portal page should open. so how to pass username and password with the portal url.

    This is not straightforward; but it is doable.
    First tell us about your portal version; portal 10.1.4 has a slightly different method of doing it and the pre-10g portals were completely different animals.
    And if you are in AS Rel 2, then the most important document for you would probably be the following:
    [Creating Deployment Specific Pages| http://download-west.oracle.com/docs/cd/B14099_19/idmanage.1012/b14078/custom.htm#i1015535]
    You might want to use it in conjunction with some metalink notes about your portal version and such a login page.
    hope that helps!

  • How to set username and password before redirecting to a RESTful webservice

    I am a .Net developer who has developed a webservice used by my ColdFusion colleagues. They are using ColdFusion 9 but I'm not sure if they have incorporated any of the newer features of ColdFusion in their apps. Here is a snippet of how they have been invoking the webmethods:
    <cfscript>
                         ws = CreateObject("webservice", "#qTrim.webServiceName#");
                         ws.setUsername("#qTrim.trimAcct#");
                         ws.setPassword("#qTrim.trimpwd#");
                         wsString=ws.UploadFileCF("#qTrim.webserviceurl#","#objBinaryData#", "#qFiles.Filename#", "Document", "#MetaData#");
                </cfscript>
    As I understand things, the .setUsername and .setPassword correspond to the Windows credentials the CF Admin set when the URL of the .Net webservice was "registered" and given its "name" (for the CreateObject statement above). I have 4 webmethods that are all invoked in this manner and this SOAP protocol works adequately for us. Please note that this ColdFusion web app authenticates anonymous remote internet users by prompting for a username and password and compares them to an application database (i.e. Microsoft calls this "forms authentication"). Because only a few Windows domain accounts are authorized to call this .Net webservice, the above code always uses the same username/password constants and it all works.
    My question involves the newest webmethod added to the .Net webservice. It requires that callers must invoke it as a RESTful service which means it must be invoked by its URL. Here is a snippet of C# code that invokes it from an ASP.NET webclient:
                string r = txtRecordNumber.Text;
                string baseurl = "http://localhost/sdkTrimFileServiceASMX/FileService.asmx/DownloadFileCF?";
                StringBuilder url = new StringBuilder(baseurl);
                url.Append("trimURL="); url.Append(txtFakeURLParm.Text);
                url.Append("&");
                url.Append("TrimRecordNumber="); url.Append(txtRecordNumber.Text);
                Response.Redirect(url.ToString());
    I assume a ColdFusion script could easily build a full URL as above with appended querystring parameters and redirect. Is there some way for the CF code redirecting to a RESTful webservice (by way of its URL) to set the Username and Password to this Windows account mentioned above? When the DownloadFileCF webmethod is hit it must be with the credentials of this special Windows domain account. Can that be set by ColdFusion someway to mimic the result of the SOAP technique (the first snippet above).
    I hope my question is clear and someone can help me make suggestions to my ColdFusion colleagues. Thanks.

    Can you clarify what you mean by "establish a different Windows identity"?  Usually passing identity to a web site or service means adding something to the request's HTTP headers.  This could be a cookie in the case of .NET forms authentication or the "Authorization" header in the case of basic authentication.
    The SOAP web service invocation code you posted does use basic authentication, according to the CF docs "ColdFusion inserts the user name/password string in the authorization request header as a base64 binary encoded string, with a colon separating the user name and password. This method of passing the user name/password is compatible with the HTTP basic authentication mechanism used by web servers."
    http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec13a13 -7fe0.html
    If you need to mimic the SOAP techinque you should have basic authentication enabled for your REST service endpoints.
    If your authentication method is different then CF developers will need to add the appropriate HTTP headers to their service calls.  Note that calling a REST service from CF would probably be accomplished using the CFHTTP tag if the service is designed to be consumed by the CF server.

  • How-to access username and password protected Java EE Web services from ADF

    The title of this post is exactly the same as this article by Frank Nimphius:
    http://www.oracle.com/technology/products/jdev/howtos/1013/protectedws/access_protected_web_services_from_adf.htm
    The article addresses the problem of securing web services using usernames and passwords, when those web services are accessed through a proxy or a data control. In the examples, the user names and passwords are specified, whether in the code or the definition of data controls. (SKING/SKING).
    In a very common scenario, users login to reach a page, for example, A.jspx, which contains a button that calls a web service, for example displayDate. Suppose that user has logged in by username/pass of (AHUNOLD/AHUNOLD) and AHUNOLD has access to the service and the page. Is there any way to pass the logged in user name and password to the webservice ? Of course we can hard-code the username in the data control definition or proxy code, but this is just one of the thousands of users who have access to the service and the authentication is not dynamic this way.
    Hope my question is clear. Wishing you all a great Christmas.

    Hi Frank, and happy new year.
    Are you implying that it couldn't be done declaratively? What is your suggestion for this problem? You know the problem... As I described:
    - I need to secure my web services, so when exposed, no one from inside network or the internet, can access the web service without proper permission
    - The web services are shown as web controls on jspx pages. The user has logged in before reaching the page. It is irrelevant to ask him to enter user name and password again.
    - I have user names, passwords and roles in Oracle Internet Directory (Identity Management). It provides some APIs and I can retrieve the usernames and attempt logging in programmically. But how can I get username and password from the session in ADF application?
    I guess using SAML or certificate could be the solution, but I have a problem with SAML, described here:

  • How to send username and password

    Hello Friends,
    When a BSP application is tested or executed,
    it opens a explorer window and asks for the server username and password.
    Is there a way where I can pass the username and password through the url so that the user nedd not know the username and password but directly can open the browser and use the application.
    Regards,
    Raju...

    Hi,
    A golden rule is never to state a userid passwd in an URL.
    What you need to is to set a default user in the BSP app.

  • How to supply username and password for consuming webservice in BizTalk Adaptor?

    While I hit the web service directly , I am able get response from that service, it asked for username and password, after that it processed the request and gave expected output. I am trying to consume the same web service (https) from BizTalk orchestration
    ,  it created message type , port type, binding for me , all fine, but while sending message to the webservice , it throws error like this 
    <SOAP-ENV:Fault xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wd="urn:com.abc/bsvc">
    <faultcode>SOAP-ENV:Client.authenticationError</faultcode>
    <faultstring>invalid username or password</faultstring>
    </SOAP-ENV:Fault>
    I have given username and passoword in port level. I tried basic binding, I also tried wcf_basic binding , but no luck. These bindings were generated by wizard only, I Imported those bindings , ports got created, I just added username and password in the
    port level.
    How should I supply username and password in BizTalk to get this working ? Any inputs would be greatly appriciated
    Regards
    Vivek

    Hi,
    the way to resolve this is to write a Wcf Custom Behavior.
    Several people have blogged about this and Microsoft have written some articles:
    http://social.technet.microsoft.com/wiki/contents/articles/627.using-custom-behaviors-with-the-biztalk-wcf-adapters-part-2.aspx
    http://msdn.microsoft.com/en-us/library/cc952299(v=bts.10).aspx
    The articles are old so you need to verify they still apply.

  • How to give Username and password when calling HTTP page?

    I have this code when i run this I get credentials error. How to give credentials .The authentication is set to windows in the https page. Means pop up will appear to get the credentials

    end loop;
    exception
    when utl_http.end_of_body then
    utl_http.end_response(resp);
    END;
    When i run this i get
    <html xmlns="http://www.w3.org/1999/xhtml">

    <title>401 - Unauthorized: Access is denied due to invalid credentials.</title>
    <style type="text/css">

    Basic authentication is set using the UTL_HTTP.Set_Authentication() call.
    If you are using a proxy and need procy authentication, you can set the username and password for proxy access, as part of the proxy URL. E.g.
    utl_http.set_proxy( 'http://proxyuser:[email protected]', null );NTLM (Windows NT LAN Manager) authentication is proprietary and not part of the HTTP specifications. If that is needed, try and use the username and password as part of the URL - or do some research on how to manually perform NTLM authentication.
    If you are using HTTPS, you need an Oracle Wallet with that server's certificate (making it a trusted certificate), and then set/use the wallet using the UTL_HTTP.Set_Wallet() call. See sample code in {message:id=10820182}.

  • How to send username and password to XISOAPAdapter

    Hi,
    Can someone please provide a sample piece of source code showing how I can invoke the SOAP Adapter, sending an XML payload and also pass the username and password?
    Many thanks
    Brian

    Hi Peter,
    You're correct. We actually have a mobile c# client running on smartphones (some Pocket PC 2003, some Windows Mobile 5 and now Windows Mobile 6). We are attempting to convert from Business Connector to PI.
    Because of scalability issues with SAP Web Dispatcher we are not using it, but instead we are going PDA <-> Microsoft ISA Server (using Active Directory cert authentication) <-> PI <-> ECC
    So we need to provide a client Certificate for ISA but also username/password for XI SOAP Adapter
    The problem is there seems to be limitations in the mobile c# SSL capabilities so we are trying to understand whether there is some way to send the username and password as header variables.
    thanks
