  • What are the different messages that OCOD may return for a web service requ

    Hi,
    Please give me feedback on the questions below, concerning the limitations of web service, and messages which may return.
    1) What are the different messages that OCOD may return for a web service request? I need all the messages of all the scenarios which OCOD can meet, for example:
    - If the file is rejected (Error message)
    - If the file is accepted (to clarify that the records have been created)
    - if the application is unavailable (maintenance or web service is down)
    2) How many request can we send simultaneously, and how many records we can make per second?
    Best Regard,

  • Designer beginner's question: How to populate form with XML web service output?

    sorry, here is yet another Adobe Designer beginners question: <br /><br />My form uses a webservice data connection which returns <br />an xml-string like this: <br /><br /><?xml version="1.0" encoding="utf-16"?> <br /><CurrentWeather> <br />  <Location>Sion, Switzerland (LSGS) 46-13N 007-20E 481M</Location> <br />  <Time>Apr 26, 2007 - 09:50 AM EDT / 2007.04.26 1350 UTC</Time> <br />  <Wind> from the WSW (240 degrees) at 15 MPH (13 KT):0</Wind> <br />  <Visibility> greater than 7 mile(s):0</Visibility> <br />  <SkyConditions> partly cloudy</SkyConditions> <br />  <Temperature> 80 F (27 C)</Temperature> <br />  <DewPoint> 46 F (8 C) </DewPoint> <br />  <RelativeHumidity> 30%</RelativeHumidity> <br />  <Pressure> 29.88 in.

    The question is still unanswered!
    Let me give some details and break up the problem
    in more specific questions:
    - In Designer 8.1 I click new data binding --> wsdl -->
    http://www.webservicex.net/globalweather.asmx?wsdl
    A message box comes up and says "cannot load wsdl file"
    ==> 1. Question:
    Why maybe refuses Designer to load the http-wsdl,
    although this option is explicitly allowed?
    - When I save the wsdl to a file, Designer loads it
    without any problems. The web service uses two input parameters
    (CountryName and CityName) and returns an xml-string GetWeatherResult)
    like the one in my first posting. I drag these fields from the binding view to my form, and it runs ok!
    - THE PROBLEM IS, THAT I NEET TO EXTRACT THE ELEMENT FIELDS
    FROM THE RESULT XML-STRING!
    ==> 2. Question:
    How to extract xml element fields from wsdl output into a form?
    - I tried with eclipse and XmlSpy to build a modified wsdl file
    with structured output definition, so that the specific element fields
    show up in the data binding view and are usable to my form,
    and the modified wsdl maps consistently to the web service result string.
    So far without success: In the PDF -preview or Reader-
    when the wsdl-binding is executed and the web service output
    should show up in the result fields, just nothing happens.
    ==> 3. Question:
    Can this strategy to provide a "modified wsdl" possibly succeed,
    and how?
    ==> 4. Question:
    Is is possible -and how?- to check whether an xml string
    is valid as web service output against the wsdl-definition?
    ==> 5. Question:
    How to debug a web service connection with Designer?
    - Finally I tried to find a way to load the result xml-string
    into a local var in the script editor and parse it, much like:
    var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.load(DataSet.MyForm.GetWeatherResult.rawValue);
    ==> 6. Question:
    Is it possible -and how?- to use a framework like dotnet?
    How to utilize SAX or DOM in Designer?
    Many thanks and appreciations for your help!!

  • Create Java Web Services in RAD 7.5

    Hi,
    I am new to web services and am looking to create web services in RAD 7.5. Can someone suggest some useful references for beginners for web service development in RAD 7.5?
    Thanks.

    How about forgetting about RAD 7.5 for now and just learning how to create webservices.
    Just google for "jax-ws tutorial" and learn them in an IDE independent way. Should then be easy to adapt to your IDE (or others) later.

  • Is there a new version of the book "Beginning Java Web Services"?

    I am new to programming web services with Java. Is Beginning Java Web Services a recommended book for a beginner? Does it have a newer version as the one available was written in 2002. Can anyone suggest a latest beginners guide book?

    The MD387LL/A, MD388LL/A, and MD389LL/A are the latest models in the USA and Canada. It's the same in other countries, except for the LL.

    Hi James,
    Thanks for the quick reply.
    We've tried to call that web service from an HTML designed in Visual Studios with the same username and password and its working fine.
    But on the BPEL console, we are getting the error as mentioned.
    Also if you can tell me how to set the user name and password in the header of the parter link.I could not find how to do it.

  • Unable to capture return values in web services api

    At the time of login to web services if my server is down ,
    it returns following error :
    java.lang.StringIndexOutOfBoundsException: String index out of range: -1
            at java.lang.String.substring(String.java:1438)
            at java.lang.String.substring(String.java:1411)
    I want to capture this error so that i can try another server to login. how do i capture this error
    Another place where i want to capture the return Value is when i look for a report on the server
    rh = boBIPlatform.get("path://InfoObjects/Root Folder/"src_folder"/" + reportName +
                               "@SI_SCHEDULEINFO,SI_PROCESSINFO" ,oGetOptions);
    oInfoObjects = rh.getInfoObjects();
    CrystalReport = (CrystalReport)oInfoObjects.getInfoObject(0);
    Here if the report is not there on the server , it returns a null handler exception.
    but if i try catching it by checking my responsehandler is null  like rh == null  it does not catch it.
    Any help will be appreciated
    thanks

    Ted : i have two cases
    1)   server = server_st.nextToken();
        providerURL = "http://"server"/dswsbobje/services";
        sessConnURL = new URL(providerURL + "/session");
       Connection boConnection = new Connection(sessConnURL);
       Session boSession = new Session(boConnection);
      EnterpriseCredential boEnterpriseCredential = new    EnterpriseCredential();
                  boEnterpriseCredential.setLogin(userid);
      boEnterpriseCredential.setPassword(pwd);
      boEnterpriseCredential.setAuthType(auth);
    SessionInfo boSI = boSession.login(boEnterpriseCredential);
    I have got a list of servers running web servcies stored in my tokens. when i pass the first server name say " test:8080" and that server is down , i want to catch somewhere in the code above that it did not get the connection so that i can loop back and try with the second server say test1:8080
    This is for failover purposes.
    at present when i was trying to capture return value of boSI it  breaks giving the error
    java.lang.StringIndexOutOfBoundsException: String index out of range: -1
    at java.lang.String.substring(String.java:1438)
    at java.lang.String.substring(String.java:1411)
    2nd case :
    I am geeting reports from the server and scheduling them:
    i run the following code which works fine if reports is there
    rh = boBIPlatform.get("path://InfoObjects/Root Folder/"src_folder"/" + reportName +
    "@SI_SCHEDULEINFO,SI_PROCESSINFO" ,oGetOptions);
    oInfoObjects = rh.getInfoObjects();
    CrystalReport = (CrystalReport)oInfoObjects.getInfoObject(0);
    Here if  the  report  is not there on the server  then i should be able to catch from the response handle rh that it has got a null value.
    but rh does not return a null value 
    the code ultimately throws a null handle at the following line
    CrystalReport = (CrystalReport)oInfoObjects.getInfoObject(0);
    i am not able to catch the null value there also.
    hope you got my issue.

  • How to allow access to web service running under ApplicationPoolIdentity

    Hi All,
    I have a WCF web service hosted in IIS 7 (or maybe 7.5, whichever comes with Windows server 2008 R2) using DefaultAppPool running under ApplicationPoolIdentity per Microsoft's recommendation. The web service needs to call a stored procedure to insert data
    to a db. The web server is on a different VM than the database server. The db server is running SQL 2008 R2. Both VMs run Windows server 2008 R2.
    When the web service tries to connect to db, it encounters this exception:
    Exception in InsertToDb()System.Data.SqlClient.SqlException (0x80131904): Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.
       at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection)
    Here's the connection string in web.config:
    Application Name=somewebservice;Server=somewebserver;Integrated Security=SSPI;Database=somedatabase;Connection Timeout=60"
    How should I configure SQL security to make this work?
    Thanks in advanced.

    Thanks for the link Dan. Maybe I'm the one who cause the confusion :)
    If I understand you(and Erland) correctly, you suggest using a custom, domain account for application pool identity. However, if we do that, our IT will need to maintain those accounts, and they don't  want that. So I'm choosing a built-in account called
    ApplicationPoolIdentity as the application pool identity, but it's not working. Network Service, on the other hand, works, but my boss wants us to follow MS's best practice.
    What's puzzling is that according to this: http://learn.iis.net/page.aspx/624/application-pool-identities/, both Network Service and ApplicationPoolIdentity uses machine account to access network resource (like db in this case), but in my case, Network Service
    works, but not ApplicationPoolIdentity.
    Hallo Stephen,
    with respect - it seems to me that only idiots are working at your IT ;)... It is absolutely useful to work with "service accounts" created within the domain. That's the only way to manage and control accounts!
    If you want to "pass through" the identity of the web user (SSO) you have to check whether the app pool is set to "allow impersonate". As far as I understand the ApplicationPoolIdentity-function the app pool will create a unique user named as the service.
    I assume that will not work with the connection to the sql server because this user is unknown.
    Local Service will not work because it's restriction is located to the local machine.
    Network Service will work because access to network resources will be available.
    So my recommendation is to use a dedicated service account or impersonation:

  • How do I use the Web Services API to query orders?

    The help doc states, "you can retrieve details for purchases including products purchased, payments received, and their status." The only additional info is at the link to eCommerce-Related Web Service, which does not include any information about retrieving "products purchased, payments received, and their status."

  • Web Service deployed with admin_client is not working

    Hi,
    I'm usung SOA Suite 10.1.3.1 and Eclipse WTP 3.2.2.
    The thing is that I developed a Web Service with Eclipse using the plugin for generating web services. Then I exported my project to a .war file from eclipse as well.
    For deploy my web service in oc4j, I tried from the oc4j console in Applications --> Deploy and Next-Next wizard and using the .war file generated by Eclipse. I got the application deployed and I can check that the wsdl is working in http://localhost:8888/Hello_Web2/services/Hello?wsdl
    But the main problem is when I try to deploy using the admin_client command tool running the command: java -jar admin_client.jar deployer:oc4j:opmn://localhost/home oc4jadmin welcome1 -deploy -file d:\TEMP\Hello_Web.war -deploymentName Web5 -contextRoot "/". Everything seems right, I can see the application created in the console, but when I try to access to the web service using "http://localhost:8888/Hello_Web2/services/Hello?wsdl" I get and Http 404.
    What is wrong with the command method?
    Many thanks in Advance,
    Alberto

    Hi,
    As the custom web part works well in other browsers, the issue may be related to the IE itself.
    Have you tried the methods below?
    Use compatibility mode to check whether it works.
    Open IE->Tools->Compatibility View Settings
    Add the site into Trusted sites to check whether it works.
    Open the IE->Internet Options->Security->Trusted Sites->add the site into the zone
    What’s more, you can also switch the Document mode to IE 10 or lower to check whether it works.
    Thanks & Regards,

  • Questions on using a SOAP web service's data in a Crystal Reports report

    I'm attempting to create a report using CR 2008, accessing data from a SOAP web service. I've run into a few problems, and need some advice.
    1) CR doesn't seem to support WSDL files that use relative URI imports (for example, I have a relatively complicated WSDL file that imports other WSDL files and schemas using relative URI locations). To solve this problem, I have downloaded all of the files to my local hard drive, and changed the "location" attributes to point to local files. Is there any other solution to this problem?
    2) CR doesn't seem to support circular references within schema files. To solve this problem, I have removed circular references from my local schema files. Of course, my actual web service will still potentially return data structures with these circular dependencies. Is there any other solution to this problem?
    3) CR doesn't seem to support request documents that allow for arrays of elements. For example, my schema allows the user to specify an array of Instruments that should be returned by the web service. In the meantime, I have changed the schema to only specify single instances of the Instrument element in the request. Is there any other solution to this problem?
    4) CR doesn't seem to support empty values for optional attributes that are specified in the schema. So, when the "Enter Values" parameter form appears, I am required to enter values for these attributes, even though they are listed as optional in the schema. To avoid this problem, I have commented out the optional attribute values in the schema. Is there any other solution to this problem?
    5) When the schema specifies that a value is based on a restricted simple (string) type, the CR parameter form shows a drop list with ellipses (...), but the drop list does not contain the enumerated types specified in my schema. Instead, I must manually enter a value. Do you know of any reason why the drop list is not populated?
    6) The SOAP response document from my web service is relatively complicated. So, in the "Data" page of the Standard Report Creation Wizard, each and every XML element level of the response document listed in the schema is shown as a separate entry. If I choose just the top level element ("fetchInstrumentSetResponse"), then very little data is shown on the next page of the wizard (only the ID attribute). But, if I select each and every element type from the response document, CR prompts me for the request document parameters for each row I have selected (I see the same form 30+ times), even though there really should only be a single SOAP request to the web service to return this response document. It seems to be treating each of these elements as a separate "database table", with a different query string for each. Am I using this feature incorrectly?
    If you can point me to somewhere in the documentation that handles this in more detail, that would be great (all I could find were the step-by-step instructions on how to connect to a web service as a data source).
    Thanks!
