Error Message "No logical port exists to call web services" installing SM7

I am trying to use SLM to download a service stack.  However, the option is not available in step 2.5.  There is an error message "No logical port exists to call web services".  I have performed the Wizard install, but the Wizard seems to have left out this step.  I have looked around for documentation on how to configure the port, but cannot find anything more useful than comments to the effect that I should configure the port.

I found the problem, I think, although I am now on to the next problem.  "Web Services for software lifecycle manager not available'.
The documentation is lacking.  When the RFC connection is set up, the user id is j2ee_admin, using the install password.  This is not specified anywhere in the install instructions that I could find, there is only a reference to a 'user id and password'.
The LPCONFIG is used to create a logical port, that ties the RFC to the LP.  However, no name is specified that is to be used for the LP.

  • About logical port used to call Web service

    Hi Experts:
    I found that logical port can be created either from "LPCONFIG" or "SOAMANAGER"， They can't be found from the other transaction. What's the difference between them? Which one should be used in cases?
    Wayne

    One is a SAP GUI based transaction and the other is a WebDynpro based transaction.  SOAMANAGER controls many more things than just logical port maintenance though and is the central location for runtime web service configuration.  It's available with NW 7.0 SP14 or higher.  You can still use either transaction after NW 7.0 SP14, but get in the habit of using SOAMANAGER.

    Without far greater details as to what you are doing, what you have installed, and what you have tried, not much can be offered. All that I can gather from the information you provided is that the server name you are trying to contact either is not responding or is invalid. If you have Forms installed on your local machine (for example using Developer Suite), try using localhost rather than the hostname. For example, http://localhost:port/forms/frmservlet?form=yourform

  • "Missing port information" when calling web service

    I have implemented a web service that works fine as long as I use primitive types as arguments and return types, but when I add a method that takes a user-defined class as an argument, I receive the following error when calling any of the methods in the web service:

    Anyone know why I receive this error?

    I am also seeing this same error. I have rebuilt and redeployed the service several times, but am still stuck getting this error. Strangely enough, the Tomcat server where the service is hosted is not reporting this type of error. Instead, it is recording an error 500 (Server Internal Error) each time I try to execute one of my services. I trimmed out the meat of the service and configured it so that it would echo the input parameters to the output (they are actually in/out params) but even this reduced configuration gives an error 500. I am inclined to suspect my deployment, but I have checked it several times against the examples.
    Anyone else see the error 500 reported as missing port information?

  • Logical Port Problem using a Web Service

    Hi.
    I have created a simple web service and imported the model succesfully into my webdynpro component. However, when I execute the web service method, I just get the following error:
         "Logical Ports loading problem. Parser error."
    I'm new to NWDS, but my application did work when I first used it, because my web service throws an exception and this was  displayed correctly in the application.
    Could this error be due to Internet explorer connection settings on the Duiscovery server? (We have a few exclusions in there).
    If I type in the url of my web service manually into IE on the discovery server, it returns the expected results, so I know my web service is working.
    There also seems to be a problem with my NWDS install, because if I change any of the properties of the Logical Port, the save icon isn't available, and shutting the properties page and reopening it restores the original settings.
    Any help would be greatly appreciated, as this is driving me nuts!
    Many thanks in advance.
    Nigel

    OK, so I've found the answer to the proxy settings on the client - they are stored in
    <InstallDIR>\Workspace\ .metadata\ .plugins\com.tssap.config\pref_store.ini
    For no proxy, change the contents of this file as follows:
    #Tue Apr 15 10:09:09 ACT 2008
    proxyHost=
    sapInitialized=true
    proxySet=false
    applyNoProxy=true
    proxyPort=
    Then save it, delete the logical port on your model and then create a new logical port from your WSDL.

  • Error message when trying to connect to a web service

    Hi all,
    I am trying to consume a third party web service using the
    attached code and i get this big massive error about complex types:
    [The following information is meant for the website developer
    for debugging purposes.
    Error Occurred While Processing Request
    Complex object types cannot be converted to simple values.
    The expression has requested a variable or an intermediate
    expression result as a simple value, however, the result cannot be
    converted to a simple value. Simple values are strings, numbers,
    boolean values, and date/time values. Queries, arrays, and COM
    objects are examples of complex values.
    The most likely cause of the error is that you are trying to
    use a complex value as a simple one. For example, you might be
    trying to use a query variable in a <CFIF> tag. This was
    possible in ColdFusion 2.0 but creates an error in later versions.
    Has anyone encountered this before or what this may
    mean....thanks
    Code:

    What kind of data is returned by your callcredit webservice?
    Try performing a cfdump on "io".
    Also, the cfinvoke/webservice method usually generates the
    SOAP wrapper around your webservice arguments. You may want to try
    just passing the XML expected by Job5314 (unless, of course, the
    method is expecting a full SOAP message as a parameter).
    i.e.
    <cfsavecontent variable="strpost2">
    <pwdchangerequest>
    <oldpwd>oldpassword</oldpwd>
    <newpwd>newpass</newpwd>
    <confirmpwd>newpass</confirmpwd>
    </pwdchangerequest>
    </cfsavecontent>
    <cfinvoke
    webservice="
    http://localhost/callcredit.wsdl"
    method="Job5314"
    returnvariable="io">
    <cfinvokeargument name="io" value="#strpost2#"/>
    </cfinvoke>
    <cfdump var="#io#">

  • Error when generating logical port in SOAMANAGER

    Hi,
    When generating the logical port in SOAMANAGER transaction I get an error message 'SRT Framework exception: Uninstantiated object "subject sidl service" in method IF_SRT_WSP_CONFIG_SIDL~CREATE_CLNT_CFG_FROM_WSDL_D of class CL_SRT_WSP_CONFIG_SIDL'.

    Kind regards,

    Hi,
    I, by mistake, reported the same problem; however the problem is that I referenced the WSDL without endpoint (WSDL service name....). I took this URI from Servces Registry, but was wrong (altough on the SR there were a valid binding+endpoint).
    I put the right IRU pointing to the compete Service COntract (with endpoint reference), and it worked.
    If you did't solve the problem, try to opern on the browser the URI you are referring to, and see, at the end if it contains the endpoint like that:
    <wsdl:service name="zsMy2ndCodeFirstWebService">
      <wsdl:port name="zsMy2ndCodeFirstWebServiceBinding" binding="tns:zsMy2ndCodeFirstWebServiceBinding">
      <soap:address location="http://xyz:8000/sap/bc/srt/rfc/sap/.....my service operation..." />
      </wsdl:port>
    </wsdl:service>
    Hope this help.

  • Error while determining logical Port

    Hi
    This is a ECC to SRM scenario:
    I get this error in the Call Adapter step. I am using WS Adapter at the receiving side.
    "Error while determining logical port Cannot find logical port for agreement abc and interface xyz"
    Why do I get that error and any suggestions ?
    Regards
    Harish

    Baskar,
    I didn't fix any issue. I was trying tofind out why the error happens. There is a proxy created at ECC side. I saw that. But target is using WS Adapter and it's that adapter which is throwing errors about logical port.
    I read the blog but couldn't figure out. Does WS Adapter need proxy code? Can it work without proxy code? I don't see any proxy code for receiver WS Adapter. I was wondering whether the absence of the proxy code gave this error about logical port
    Regards
    Harish

  • Error creating a logical port from a WSDL in tx SOAMANAGER

    I created a client proxy successfully in SE80, using a WSDL.  I then run tx SOAMANAGER to create the logical port.
    I type the service name, logical port name, and specify "WSDL Based Configuration".  I select to load the WSDL from a file on my pc.  I use the same WSDL I used to (successfully) define the client proxy.  I get the error message:
    SRT Framework exception: Error in WSDL parsing: Exception occurred in library handler
    Any ideas?
    thanks
    matt

    IF possible can u type in ur WSDL, it might be the WSDL def itself. Also can u tell me what u r trying to do, SOAMANAGER has been super tricky for me, try binding it with the third option if u trying to test ur service

  • Sales Order Error Message 'Product does not exist in system'

    Hi Gurus,
    we recently upgraded from CRM 4 to 7.0. There is a ECC attached (which was also upgraded from 4.7 to 6.0 before).
    Scenario: materials are replicatd from ECC to CRM. All mandatory customizing objects were initially loaded succesfully.
    Because of the upgrade we already have "old" products in CRM. We requested a single product from ECC, the bdoc went through with green. The product can be found via commpr01 and also on database in comm_product. But when try to add the product to an sales order e.g. quotation, it gives the error message "product does not exist in the system.
    We then tried to delete that product using the report com_product_delete_single. When entered the selection criteria for that report, we used the f4-valuehelp to enter the product. We found the product and then executed the report. But gives the message 'product not found'.
    We also created a product for testing purposes directly in crm, but it shows the same behaviour in sales orders and for the deletion report.
    Please help me with that issue. Your help will be highly appreciated!!!
    Kind regards
    Hannes

  • Error - "Message Interface does not exist in any software components"

    HI
    This is an Idoc sender - SOAP receiver scenario.
    When I try to create the receiver determination, I get a warning message -
    " Message interface does not exist in any software components installed on this business system"
    I checked all the usual things & also reimported the IDoc metadata.
    Any suggestions are appreciated!
    Thanks
    Rachana

    Hi Rachana !!
    You should also check  if the given idoc type in mapping is the same that in the WE20.
    Also try to reactivate your integration directory objects by making any dummy changes.
    Check your receiver business system (I mean XI), that the logical systems are ok.
    Check this document (page 31):
    https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/2f2a9fa2-0a01-0010-32ac-d281db722b86

    hey guys just updating you all.. i wrote previously how my ovi store wasn't working, it gave me an error message 'resource does not exist'. i did soft/hard reset, also uninstalled ovi store and reinstalled STILL it wasn't working. It lasted a day. And today it's working fine. i think it was a problem with their server. It sorted it self out
    But guys i did contact the team, and i got a reply that said i should do the following if it still doesn't work:
    1. GO TO MENU
    2. GO TO INTERNET
    3. CLICK ON WEB
    4.GO TO OPTIONS
    5. GO TO CLEAR PRIVACY DATA
    6. DELETE CATCHE AND COOKIES

    If not guys, then i wouldn't worry. Just like mines, yours should sort it self out

  • Error Message : Object does not exist (status management)

    Hi Gurus,
    I am working on tcode IW52(Change Notifications). and using badi's for validations at different points.
    1. Order level,
    2. Notification,
    3. Task level validations.
    In the task level validations, I have an requirement that if certain condition is met, than user should not be able to delete the task. I have no problem doing that, I am able to restrict it.
    Now the issue is :
    Say you have 6 tasks, and condition is met for the 5th task and I try to delete it. then the error message "can not delete task" is getting triggered from the badi.
    and after this error message if you try to do any functionality on the 6th task, I am experiencing error message "Object does not exist (status management)".
    Is anyone aware of this error message, any suggestions are highly appreciated.
    Thanks in advance.
