Accessing webdynpro applications externally

Dear all,
We are using ESS in EP 6.0 SP18 and ECC 5.0 which is based on web dynpro.  When ever I acccess the Web Dynpro based ESS applications, the requests are going to http://portalserver:50000/webdynpro...etc.
We need to make our ESS WebDynpro applications externally accessible via internet.  I dont think opening up 50000 port is a good option.Please advise.
Thanks,
-Bharath

  • Cannot access WebDynpro application:com.sap.tc.webdynpro.services.exception

    Hello gurus!!
      I am trying to access the "Emergency address" from the LWE and I am getting this error "Cannot access Web Dynpro application: com.sap.tc.webdynpro.services.exceptions.WDException$DummyLocalizableTextFormatter@76829226". Could anybody please suggest what could be wrong with this action "Emergency Address"?
    Thanks much for your help with this,
    Maria Kutty Somori....

    Hi Yugandhar/Siddharth,
       Emergency address is the standard callable object for Execution that is part of the Standard Life and Work events. I have customized to reorganize the actions depending on our requirements and i have created a different folder structure and different order of execution of callable objects.
    How do I fix this "cannot access Webdynpro application" error? Please suggest.
    Thank you so much,

  • Error occured while accessing WebDynpro Application

    Hi,
    I am getting below mentioned error when i am trying to access WebDynpro application through Portal.
    Appropriate roles have been assigned to me in Portal as well Dynpro.
    What is the cause of this error message ?
    Is this something to do with Authorization or User Mapping ?

    Hi Rohan,
    Might be the user you are using is not in the Admin group.
    You can assign the user into that group using the Visual admin or
    User management by logging using the j2ee_admin user.

  • How to call WebDynpro application from an external application

    Hi All,
    I have an external application, from which an existing webdynpro application should be accessed.
    Is there any way i can access WebDynpro application through an URL, so that i can access the same from the external application.
    I have to pass a parameter also in the url from extrenal application for which that data should be displayed.
    Thanks
    Supriya

    You can call a web dynpro application from an external app by using the web dynpro application url.
    Go to WD application in studio and look at the properties tab, you will find the url.
    It should be something like this:
    http://<host>:<port>/webdynpro/dispatcher/<namespace>/<dc name>/<application name>

  • Accessing HTMLDB application outside of firewall....

    If I develop an HTMLDB application on my database server that is inside my corporate firewall, how do I have people outside the firewall access it. Do I need to open one or more ports on the firewall? Using the same situation, is it possible to access this application externally from a Portal page?
    Thanks,
    Brett

    As already mentioned this issue is not really an Apex issue, but an issue between your webserver ports and your InfoSec firewall folks. You also want to consider whether the data is sensitive enough to warrant HTTPS with SSL encrypted traffic rather than straight HTTP. At our institution we generally require HTTPS for corporate data but since the encryption requires a lot of processing it affects your application server performance. We have gone to a BigIP switch for all our HTTPS public ports, then from BIgIP to the app server we are behind the firewall and run http. So the Public Portal URL is https to the BigIP which then negotiates with the App servers. Our Network BigIP engineer works out the fiewall rules with our InfoSec folks. This approach offloads all the encryption processing to a dedicated hardware switch rather than to the app server. BigIp also allows for additional rules that can be set up to force certain URLs to require a VPN, for example.

  • Unable to access Webdynpro abap application externally

    Hello,
    We have created a WebDynpro ABAP application,it is a simple application talking to the ECC.
    We are able to run this application on our portal within the network,but when we try to access the application from an external network it says Internet Explorer page cannot be displayed.
    We are not using any Web Dispatcher.
    Thanks
    Mayi

    You need to talk to your network administrators.  Probably your ECC system is within your corportate network and behind a firewall that doesn't allow requests in for these servers/ports.  You need to work with your basis team and network team to open the appropriate ports and IP addresses in the firewall. However you should also still provide protection for your ECC system with some forms of reverse proxies as already suggested.  This is a security process you should perform with your local admins.  This isn't really a Web Dynpro ABAP related process or inquiry.

  • Accessing WebDynpro ABAP application from external network

    Hi All,
    I have developed one application in webdynpro ABAP.
    Now my requirement in to access this application through internet.
    I dont want to use portal to run application.
    Is it possible to access through internet ?

    You can access the webdynpro application via internet with the help of SAP Web Dispatcher. Basis team will install the web dispatcher and then machine can put into a DMZ area which in turn can be opened to Internet with necessary controls.

  • Access to application when external and internal address of EP are differen

    I have a problem with access to application in portal. I deployed the application (ear) and it is available by address http://noss.inside.bcc.com.pl:54100/forum/index.jsp in our intranet. External address of portal is https://portal.bcc.com.pl. My application is unavailable outside the company, because in url iView there is an address of internal network. I've tried to use relative address /forum/index.jsp, but it doesn't work. Is there any kind of iView, which can solve my problem?

    Hi Julia,
    have a look at this Topic: <a href="https://forums.sdn.sap.com/thread.jspa?threadID=65920">How does portal connect a user to internal web site</a>. Basically it is the same problem. Unfortunately Jeremy had not described the solution in detail.

  • On imac 10.6.8 using current version of Aperture.  How can I access the Aperture Library  on my external hard drive that I use with time machine for backup?  I can only access the application but not the library..

    On imac 10.6.8 using current version of Aperture.  How can I access the Aperture Library  on my external hard drive that I use with time machine for backup?  I can only access the application but not the library..

    Go into Time Machine (the program not the bundle on the extrnal disk) and using Time Machine's browser go to the Folder where the library lives. You could look in the library bundle in Time Machine but that won't really tell you much,
    If you want to make sure it truely has backed up your library you will need to restore it and open the restored library with Aperture.
    If all this still has you confused you need to read up on Time Machine in order to get a feel for how it works, for what it is doing and for how to restore files from it.

  • How to access custom JAVA webdynpro application from an iPad?

    Hi,
    We are trying to access custom JAVA webdynpro application from an iPad, but nothing is opening up from the iPad browser.
    What can be the possible reasons for this? Any kind of SICF enablement or opening up of ports in the network?
    Any inputs are welcome!!
    TIA,
    Regards

    Hi,
    it is possible to show Java Web Dynpro applications on a mobile device in general, but the controls and the ui should be optimized for the mobile device.
    Safari devices are not officially supported so far for Mobile Web Dynpro.
    Supported are Windows Mobile devices and Blackberry devices. I also got some good results with Symbian devices.
    You can find more inforamtion on Mobile Always Connected at:

  • Error in WebDynpro Application in accessing "MIME Repository"

    Hi All,
    I am writing a XML file to Mime Repository from WebDynpro Application.
    To do this, I developed the below code:

      DATA url TYPE string VALUE
    '/SAP/BC/WebDynpro/SAP/PUBLIC/BC/SSR/uuielibs/example.xml'.

    In calling the method IF_MR_API~PUT, I have passed "X" to I_SUPPRESS_PACKAGE_DIALOG to avoid Transport Request screen.
    Can you please suugest how can I overcoem this issue.

    Leha,
    Is this RFC expecting any mandatory parameters ? if that is the case make sure that you are sending the expected type mandatory parameter.  (you can print a message on the screen and verify this)
    If you are sure that you are sending the correct details to execute RFC, Please turn on the debiug session for the portal user in the backend and see whether the values are passing from the portal or not.
    How to switch on Debug mode in the backend for the specific user:
    Requirements:
    1. Make sure the user id existed in Portal and SAP Backend.
    2. Setup the debug mode for the user in the backend
    3. Run the application from the portal
    4. While executing the application from the portal , The backend stops the execution to debug, so from here you have to execute the FM step by step and verify whether you are getting the values from the portal or not.
    Steps to switch on Debug mode in the backend:
    Logon to ECC System>> To access the function module use SE37 tcode from the SAP Easy access menu>>Enter the Function Module name and click on Display>>From the SAP Menu click on Utilities>>Settings >>Debugging >>Enter the user ID to switch on the debug mode and Enter.
    Now the user ID is switched on for Debug. Go to the Function module Source Code>> palce the cursor at the start of the soruce code>>From the Menu go to Utilities>>BreakPoint>>Set?Delete Break Point
    This will set the break point for the mentioned user id and now you can veryfy the values on the backend.
    Once you complete the debug process please turnoff the debug mode.
    Thanks
