J2EE application access from Portal - P4ObjectBroker

hey all,
I want to access access a J2EE application (Web Service) from a Portal Component. The documentation at http://help.sap.com/saphelp_nw04/helpdata/en/c0/a584409db95537e10000000a1550b0/content.htm shows an example.
They import the package <b>com.sap.engine.services.rmi_p4.P4ObjectBroker</b>. I cannot find the package on my system, i.e. my local portal installation.
Does anybody know what kind of package is required, or where I can find this package...
many thanks in advance
cheers Sascha

Hey Sascha,
the P4ObjectBroker is part of the implementation of the P4 Provider Service on the J2EE Engine. It is part of the com.sap.engine.services.rmi_p4 package.
If you can't find it I recommend you to search it using ClassLocator, it is a plugin that indexes all your packages and locates the propar class for you.
You can download it at this link: http://sourceforge.net/projects/classlocator
Read the instructions of how to use it with the NWDS, it is really simple. If you need more help do tell me.
Regards,
Roy

  • Partner application access to portal login info

    How can an SSO partner application (Java) tell whether or not a user has logged in to Portal?
    I need to log activity in a public application servlet, so I'd like to log the user as PUBLIC if not logged in or as their actual userid.
    I don't seem to have access to this info until the user has visited a secure part of the app.
    Any pointers would be appreciated.
    Thanks
    Rob

    DIY answer ...
    The cludge I used to get round this was ...
    Make a PL/SQL item which displays a Login or Logout link as appropriate, based on the current userid from portal.wwctx_api.get_user.
    The login link goes to a secure portal page called FORCE_LOGIN, passing a URL parameter called nextPageURL which contains the URL of the next page to show after the login is complete. You can use portal.wwpro_api_parameters.get_value( '_pageid', 'a'); to help build the current page URL if you want to retun to the current page.
    The FOIRCE_LOGIN page contains a PL/SQL item which builds an IFRAME whos src is a URL to my app servlet ForceLoginServlet, passing on the nextPageURL parameter. Use portal.wwpro_api_parameters.get_value( 'nextPageURL', 'a'); to help with that.
    The ForceLoginServlet is a secure servlet (set up in web.xml) so that forces a silent authentication to my app. All the servlet does is display HTML to redirect back to the URL in nextPageURL.
    Horrible! But it does the job.
    Anyone who know a better way of doing this, please tell me.

  • Access to Guest Folder requires login when accessed from Portal/SSO

    We have wired XML-P to use OID and then registered it as a Partner Application in our Portal/SSO server (which also uses the same OID instance). All works well except now when we try to access the Guest folder from within Portal the SSO login screen pops-up. We have created a very simple HTML/URL portlet that points to the Guest folder and the idea is for users to have Public/anonymous access to this folder. Any ideas?

    Hi,
    You can try to enable "Turn on password protected sharing" in Network Sharing Center. After that, only people with a user name and password on the computer will be able to log into shared network folders.
    Another workaround method you can try:
    Open Run, type rundll32.exe keymgr.dll, KRShowKeyMgr, then Press
    Enter.
    In the prompt dialog, choose and delete the user account used to network sharing.

  • WebDynpro ABAP application issue from Portal after ECC 6 upgrade to SP14

    Hi,
       We have recently upgraded the Kernel, ABAP and Java stack of ECC 6.0 system to SP14. After the upgrade most of the WebDynpro ABAP applications doesn't load and just flickers when run from Portal as a WebDynpro iView, but they run perfectly fine when accessed directly using URL. These were running fine prior to the upgrade. Can someone suggest what can be going wrong.
       Will reward points for helpful answer.
    Regards
    Mukesh

    Hi Mukesh,
    As Gajendra said, restarting the service in SICF sometimes works for us, but not always.  We have also had to deactivate the entire Webdynpro node, and then reactivate it and all of the services below it.
    Obviously something changed in the SP, given that we now have to do this every time we create a new WDA application.
    Cheers,
    John

    Have you checked your Garbage Collector log file ?
    I posted some hints about how to do that in the thread "Server Performance Issue" in this forum.
    I could be that you are running out of memory after the heavy load and then everything will be slow afterwards, because full GC's might be triggered frequently.

    Appreciates your help !
    Thank You

    My first guess would be because Firefox disabled insecure TLS fallback in 37.
    We have disabled insecure TLS version fallback. If a secure site isn’t working, you can try setting the “security.tls.version.fallback-limit” preference in about:config to 1 and see if it works then.
    Weblogic out of the box does not use the newest protocols and is version intolerant.  I would need detailed config info to say for sure why PORTAL might still be working.  Are they running different Java versions for Weblogic?  Is there a mix of Certicom and JSSE being used for SSL?  Check out this analysis for more details.
    http://remotepsadmins.com/2015/01/24/ssl-weblogic/
    Let us know what you find.  Others may experience the same thing if they are configured similar to you.

  • How to programatically start j2ee application/service  from command line

    Hi all
    We have developed a j2ee application and deployed  the .ear file on SAP J2EE (Netweaver'04) engine.
    We are able to successfully start/stop the application from Visual administrator -> Deploy -> Service -> Start application (or) Stop application.
    We need to start and stop the same application programatically or via command line instead of doing it from VA.  Any thoughts from anyone on how to do it ?
    Thanks in advance.
    Regards
    Nagesh

    The cammands are there in the respective folders, these are just the batch files / .sh scripts that can be run from command line.
    /usr/sap/<instance>JC<client>/j2ee/admin
    go.sh and go.bat can run either on command line
    j2ee/configtool
    configtool.sh / configtool.bat  
    similarly for other smaller utilities. For the main server, the related commands are in exe directory of sapmnt
    /sapmnt/<instance>/exe

  • Integration of J2EE application with weblogic portal

    Hi guys,
    I have an application hosted on an iplanet web server. This application uses servlet 2.2, jsp 1.1 of J2EE platform.
    And I have a microsoft application running on .NET platform.
    I want integrate above 2 applications into webloigc 8.1 portal. What are the different ways in which i can do this and where can i find specific material on this.
    advance thanks for your help
    gopaluni

    Basically I am saying that your options are
    1. Screenscraping the apps into portlets
    2. Using SSO to login to the apps, but keepin them separate
    3. Using Web Services to consume parts of the apps and exposing those as portlets
    For our application we do 2 and 3. In many cases we just create portlets that represents views into other j2ee apps. When the users click on something, we launch the j2ee app in a popup browser. The users are already signed on, and taken to a specific detail page, add page or something within the app directly.
    Hope this helps.

  • IFS Access from Portal (Sample Portlets)?

    Just wondering if there are any sample JSP/Servlet Portlets floating around illustrating access to iFS (9.0.3 cmsdk) for document storage/management. Something that is a true portlet that lives properly within a portal environment would be ideal.
    thanks

    I was aware of the Oracle sample, but it really isn't that functional as indicated by other threads in this forum. It basically is a link to the iFS WebUI that jumps out of portal. In any case, we intend to work with the cmsdk which does not support WebUI.
    Can anyone share/point to some examples of portlets (JSP,Servlet based) that can access the facilities of cmsdk.
    thanks

    hi
    BW/ERP/CRM access from portal is governed by a single concept of single sign on  where actually you integrate them through logon ticket otherwise you can use application integrator component for user mapping
    There is step by step guide of BW 3.5 integration with portal  in sdn as well

    on similar grounds you will have CRM too
    Portal and R3/CRM/BW in different windows domains
    please do not forget points
