  • Editing application-j2ee-engine.xml file in Web Dynpro DC

    I'd like to set one of my web dynpro apps to automatically start whenever the J2EE engine is started.
    <a href="http://help.sap.com/saphelp_erp2005/helpdata/en/94/0a5b422f786255e10000000a155106/frameset.htm">This SAP Library document</a> states that you can do that in the application-j2ee-engine.xml file. However, I cannot find the application-j2ee-engine.xml file anywhere in my Web Dynpro DC. I've opened the DC in Web Dynpro Explorer view, Package Explorer view, Navigator view, J2EE DC Explorer view and J2EE Explorer view.
    Even after expanding all the folders in each view I still can't find the application-j2ee-engine.xml file.However if I search my '.dtc' folder on my hard drive I find the application-j2ee-engine.xml file in the following path:
    C:\...\.dtc\1\t\13AA2EFA530FEB42915442D10D7C71A6\gen_wdp
    How can I EDIT that file for a web dynpro component/app?
    Thanks!

    Hi Maksim. I understood that. It's just that I would prefer some method that doesn't require the developers to do something like extracting a file from the EAR file, changing the file and then putting it back in. As you probably know, some developers could handle it and some will most certainly make mistakes.
    When they do they come to my group and say "my app doesn't work" and then we have to spend time figuring out why.
    Plus, once the developers get used to doing things the automated way they're going to have a hard time remembering to do a manual step each time they do a build.
    I have heard that there may be some way to do something similar to this on Visual Administrator. I'm going to investigate that too.
    Thanks!

  • Regarding application-j2ee-engine.xml ?

    Hi @,
    Where can i find complete description for the application j2ee engine file used during module develpmnt as the entries there make the whole module work.
    I couldn't find proper details for the same file and how to correlate the same with the developed code

  • Cannot parse ejb-j2ee-engine.xml

    During installation of XI3.0 I get this error in the "Online deployment adapter framwork". Has anyone else seen this error? Here's the complete error:

    Any help will be apreciated!

    Hello Dankertsen
    This is a standard error in SAP XML Deployment file, you need to check the file ejb-j2ee-engine.xml if it starts with a space (first line) you must remove it and then update the file aii_mdt_bean.jar. and then retry again.
    Hope this will help.

  • ISA 5.0 / NWDI : web-j2ee-engine.xml / synchronization question

    Hello experts
    I wonder whether this is normal that whenever I start a synchronization on the crm/isa/web/b2c DC (or in my custom DC which synchronizes the used DCs including crm/isa/web/b2c), nwds asks me to create an activity to take into account changes on the web-j2ee-engine.xml file ?
    I select cancel each time but maybe I'm wrong ?
    Is there a solution that nwds not ask me more ? Is there a mistake in any configuration file ?

  • No ejb-j2ee-engine.xml after new EJB module project

    Hi! Can someone please help. Newbie here
    I installed SDK 1.4.2_13
    I installed Netweaver Developer Studio 7.0.09
    When I create a new ejb module project I only see the files
    ejb-jar.xml
    ejbmodule
    I miss the file ejb-j2ee-engine.xml
    How is this possible?

    I solved the problem by uninstalling SAP Netweaver Developer Studio version 7.0.09 and install version 7.0.08
    However, It's still strange why there was no ejb-j2ee-engine.xml when there was created a new EJB project module.

  • Define multiple cookie paths in web-j2ee-engine.xml

    Hello,
    Is it possible to define more than one path JSESSIONID cookie is sent to? Something like
    <web-j2ee-engine>
    <cookie-config>
    <cookie>
    <type>SESSION</type>
    <path>/irj;/login</path>
    <domain>siemens.de</domain>
    </cookie>
    </cookie-config>
    </web-j2ee-engine>
    I want the cookie to be sent to /irj and /login, but not to /b2b.
    Another solution could possibly be to change the name of the JSESSIONID cookie. Is that possible?
    Thanks for you help,

  • Where to change applications that start with start up?

    I'm running OS X Mavericks,
    I can't find out where I change the applications I had set to start automatically when you reboot the computer.

    System Preferences>Users & Groups:
    To prevent an item from opening at login, click its name once to select it and hit the '-' button below the list. This will not affect the application itself.

  • EJB Isolation levels in ejb-j2ee-engine.xml

    Can anyone explain to me why I only seem to have the option of using the 'repeatable read' isolation level in Netweaver Developer Studio?
    I'm new to SAP and Netweaver but as a seasoned J2EE developer I would have expected to find read committed, read uncommitted, serializable, as well as repeatable read.
    Is there some SAP or Netweaver specific reason why I don't get to choose these options, or do I need to enable them by configuring properties somewhere?

    Hi Steve,
    The reason is that the J2EE Engine EJB Container supports Read Committed and Repeatable Read isolation levels and Read Committed is the default one. That's why you only have the option of specifying Repeatable Read.
    For more information on locking and isolation levels please have a look at these documents:

  • How can I change application's web.xml in NetWeaver CE 7.1?

    Hello Experts,
    Please help me. I need to configure a J2EE application on NetWeaver 7.1, but I don't know how I can change the web.xml of the application.
    The web.xml of the app needs to be modified during the configuration. This can be achieved via single-file-update in VA in Netweaver 6.4 or 7.0. But I cannot figure out how to do that in NW 7.1.
    Please show me how to do that or at least give me some hints.
    Thank you!
    Jack

    Hi Jack,
    In SAP NetWeaver 7.1 and later, you use the SAP NetWeaver Administrator instead of Visual Administrator.
    To get some information on how to configure web applications, try [THIS|http://help.sap.com/saphelp_nwce10/helpdata/en/45/48a60a528608d1e10000000a11466f/frameset.htm] piece of documentation.

  • Where to change Application pool password?

    Hi,
    I want to change SharePoint Webapplication Application pool password.
    Could someone please help me , how to do so?
    Thanks.
    Badri

    Go to Central Administration -> Security -> Configure Service Accounts. Find your Web Application Application Pool from the dropdown, and you can select the Managed service account it runs under. You can also set up a new Managed Service Account here.
    Alternatively, if you need to set a Managed Service Account password, go to Configure Managed Accounts under the same section.

  • J2EE Engine - Restart necessary after changing web.xml?

    Hi people,
    do I have to restart the whole J2EE Engine after changing the <max-sessions> parameter of my J2EE-App? Or is a restart of the app via the deploy service also sufficient?
    This parameter change is done in web.xml on 620 and web-j2ee-engine.xml in 640.
    Thanks!

  • Where the deployed application is visible in Visula Administrator

    I have deployed ejb in Netweaver using the deploy tool.
    For the methods of the bean I have mapped the roles. The mapping of the methods with the roles as well as mapping of the roles with the server roles/ groups is being provided in the ejb-j2ee-engine.xml file. I could see the deployed application in the deploy tool along with the security roles mapped with the bean methods. Where I could see this deployed bean in the Visual Administrator. Also the mapping of the security roles with the server roles provided in the ejb-j2ee-engine.xml file using the <security-role-map> tag.

    Hi,
    can you be a bit more specific about what you need to do to your bean using the Visual Administrator (VA).
    The way your questions goes right now I can give you just some general answers like:
    If you want to just see the deployed application and manage it's status, you can have a look at the Deploy Server in the VA: http://help.sap.com/saphelp_nw04/helpdata/en/25/1d353e39011a38e10000000a114084/frameset.htm
    If you want to monitor the bean and change some (very limited number) of its settings, you can go to the EJB Container service: http://help.sap.com/saphelp_nw04/helpdata/en/7d/edfb2e2fa7774ea7d7e585ad943fda/frameset.htm
    Hope that helps!

  • J2EE - Engine Session

    Hi
    in one of our systems the J2ee-engine appends the JSessionId to every URL. In the other systems the session-handling is running properly cookie-based. Does anyone know where to configure this?
    TIA cb

    Hi,
    using URL rewriting to send JSESSIONID is controlled by a property in the additional deployment descriptor (i.e. web-j2ee-engine.xml) of the application. By default, JSESSIONID is sent as a cookie (if the HTTP client supports cookies), and URL rewriting in case the client does not support cookies. Setting the <url-session-tracking/> in the descriptor forces the J2EE Engine to use url rewriting always.

  • Mapping UME Roles to J2EE Engine Security Roles

    Hi all,
    is there a way to map the roles defined in UME which are used in a Web Dynpro application to those declared as part of an EJB descriptor?
    Any help is highly appreciated.
    Regards,
    Sebastian

    Hi Sebastian,
    yes, it is possible to do such mapping. And here how it works:
    1. define security roles in the ejb-jar.xml within the <security-role>. For example:
    <security-role>
         <role-name>test</role-name>
    </security-role>
    2. then you map the roles those roles to server security roles using the <security-role-map> tag of the ejb-j2ee-engine.xml descriptor.
    <security-permission>
       <security-role-map>
          <role-name>test</role-name>
          <server-role-name>myUMErole</server-role-name>
       </security-role-map>
    </security-permission>
    the myUMErole must be defined in the UME!
    Does this answer your question?
