LSO - accessing external content provider

We are trying to configure our LSO system to communication with an external vendor to provide hosted content. We have gotten as far as getting the system to make the initial request to the vendor, however it appears the return_url parameter in the request is using our internal host name, which results in them not being able to reach our LMS system.
Where do we change the return_url parameter in the request to use our externally facing host name?

Is this AICC content? If the AICC URL return parameter is determined by the URL used to launch your Content Player which is configured in the backend. You may want to have IT create a reverse proxy pointing to that server and also have an internal DNS entry created to point to that server as well.
Let me know if this helps.

How to access tables/views of an external database provider..

After much trouble I finally managed to setup a second Database Provider that doesn't display the "0 out of 0 connections are good" error by filling in the "Configuration Class" field with "intradoc.server.DbProviderConfig".
But now the problem is actually accessing the tables/views in my newly configured external database provider...
In the Configuration Manager applet when I try to add a new Table or View it only lists the tables contained in the schema of the SystemDatabase database provider (the original one), I've tried running Queries via components trying stuff like SELECT * FROM provider_name.table_name and other similar but obviously it doesn't work...
So... with that said, I just want to know how I access tables or views in my "supposedly" well conected (15 out of 15 connections are good, no errors on the Test Query) Oracle external Database Provider - After searching I was unable to find any information regading any post-provider-setup actions in the Content Server documentation - Does anyone know how to do this?
On a side note, if the database is SQLServer instead of Oracle, with the same configuration and apparently no errors on the database side (other clients access it well) the Query Test of the new database provider returns the following error:
"The provider 'TestSqlSrv' is in error. Unable to create database connection for JDBC:ODBC:SqlSrv. Unable to create result set for query 'select * from dummy'. Invalid Fetch Size Unable to create result set for query 'select * from dummy'. Invalid Fetch Size java.sql.SQLException: Invalid Fetch Size".But I won't even go there yet.... for now I would settle with just knowing how to reference information in the Oracle external database provider...

if you are able to, pick up Bex Huff's book the Definitive Guite to Stellent Content Server Development (amazon link: http://www.amazon.com/Definitive-Stellent-Content-Server-Development/dp/1590596846/ref=sr_1_1?ie=UTF8&s=books&qid=1196365101&sr=8-1)
chapter 11 is all about this.

Connect to MS Access using External Content Type

I am trying to establish connection to an Access 2013 DB from SharePoint 2013 Designer.
I am in External Content Type. My database is on local drive. When I click on Add Connection, I have the following choices,
.Net Type
SQL Server
WCF Service
Which one shall I choose for access. What would be the Database Server. The database is local.
Thanks
Mayank

Hi Mayank,
If you want to use ECT to display the data of the Access database, per my knowledge, you need to import the Access database table into SQL server, then use to ECT to connect to the SQL server table.
More information about importing an Access database table into SQL server, you can refer to the link:

Access issue relating to external content types

Hi,
I was recently given permissions in the Central Administration to edit external content types. However, when I open Sharepoint Designer and click on External Content types, I am unable to view the existing external content types that was created by another
site collection admin. The message I see is "There are no items to show in this view." I have the same permission level as this admin.
Any suggestion in regards to resolving this?
Thanks in advance!
Vidya

Hi Vidya,
For your issue, please confirm below check list:
Do you have permission to access the Business Data Connectivity Service? You can verify this by trying to open Business Data Connectivity Service management page of Central Administration in the Browser.
If you cannot open, please ask permission for yourself from the farm administrator. Reference:
Business Connectivity Services security overview.
Do you have Edit , Execute and Selectable In Clients permissions for the external content type you want to view? If not, please ask permissions for yourself. Reference:
Set Permissions to External Content Type using PowerShell.
If the issue persists, please go to Central Administration->Application Management ->Manage services on server, restart the Business Data Connectivity Service.
Reference:
External content types: There are no items to show in this view

ESS Content not showing when accessed Externally

Hello Experts,
I am experiencing an issue with our ESS portal that is not displaying the content when it is accessed externally (from outside our intranet).
Currently we can access all content from inside our own network. From outside our network we are able to log into the portal and access all tabs (content Admin, System Admin, user Admin, etc), however when we try to access the ESS, My Travel, or My Budget Tabs we get a "page cannot be displayed" error. It appears anything using WebDynpro will not load.
Internally we access the portal by going to the URL: <ServerName>.baldor.com:50000/irj/portal
Externally we access the portal by going to the URL: employeselfservice.baldor.com:50000/irj/portal
Is there some kind of mapping that we need to configure? Any Suggestions?
Any Help is greatly appreciated,
Thanks in Advance,
Steven

Problem is solved.
We had to use our external web address in the System defination in the portal.

FPN design: prevent employee from content when accessing externally

I have a portal architecture question that neither my IBM nor SAP consultant could answer in a satisfactory way:
situation: we're about to setup a federated portal network with multiple producer portals. We think we have to setup 2 consumer portals: one for internal users with full content and one for external access with reduced content (e.g. no MSS or BOBJ when accessing from the outside).
It is our understanding that the external client still directly connects with the producer portal for getting its contents so the reverse proxy has to let the URL request go through.
the problem:
an employee can find out the producer URL and directly access the producer from the outside. Since the user is known at the producer they can sign-in there and access all content.
We have security concerns and want to present sensitive content only to users on our internal network.
the question:
how can we prevent for sure that an employee accessing the portal from the outside can only access non-sensitive content.
... or ... are our requirements unusual and we should change?

Hi,
the best way for ensuring that sensitive information isn't accessible from the outside is to make this kind of information not accessible from the outside. If you cannot seperate internal and external information on seperate servers:
Content published on the portal normally is being accessed by an URL. WebDynpro is integrated as an iFrame and BI reports are executed on the BI portal.
Even if you do integrate this kind of content via FPN, they seem to reside on the consumer, but when accessed the producer URL is called. Try to put a Firewall between your consumer and producer that will only allow internal IP adresses to pass.
User -> DMZ -> Consumer -> Firewall -> Producer
The user clicks on the MSS iView that is basically an ITS or WD that calls the Producer URL. The Firewall checks the IP of the user and blocks it.
If you want to prevent the user even to see the to-be blocked content in the navigation of the consumer, you'll have to code your own navigation / dynamical role assignment that checks if the user is connected in the Intranet or Internet and constructs on-the-fly the correct navigation.

Text Fields of an External Content Type come across as Multiple Line of Text

In SharePoint 2013 I have an external content type that consists of a couple of short (nvarchar) fields (no more that 15 characters). When I use this ECT in a custom list the fields from the ECT end up as a "Note" type instead of "Text".
I am not sure how this happens. I have verified this by accessing the list via poweshell where I see the Type being as "Note" and also the SchemaXml showing the colName attribute as "ntext".
The strange thing is that initially when I created the web application and built my lists this was working.
Any ideas or pointers would be appreciated.
Thanks

Hi,
Based on your description, my understanding is that When you use the ECT in a custom list the fields from the ECT end up as a "Note" type instead of "Text".
Have you ever changed column types from "Single line of text" to "Multiple Lines of Text" in list?http://www.sharepointdiary.com/2013/09/change-column-type-in-list-using-powershell.html
External content types are made up of fields whose types are a subset of the primitive types of .NET. For each such .NET type, a rudimentary mapping to SharePoint’s field controls exists, describing a field’s visual appearance. Fields of type string for
instance will, on the new and edit forms, render as a single-line text field.
Besides, check whether the following link is useful:

SP 2013 ECT - Created an External Content Type in SPD But Not Appearing in BCS

Hello Community,
I have created an External Content Type in SP Designer 2013, and the connection and operations all seem to work fine, but the ECT List throws an access error, and when I check the BCS Service Application the ECT doesn't even appear in the list. Has
anyone else ever seen this kind of problem and if so please brovide guidance and examples for resolving it.
Thanks!

Hi Tom,
Have you created external content type from SharePoint designer 2013 successfully prevously?
And was it displayed in BCS service applicaiton previously?
Have you executed "External Content Type Operations" and saved it back successfully in SharPoint Designer like the following article?
Please check if it is related to the permission issue by using SharePoint Farm Administrator account to create this external content type.
If all above don't solve the issue, please check the ULS log for more information for troubleshooting when create the external content type.

Can't create external content type

Hi,
I'm trying to create an ECT in Sharepoint Designer for my Office365 environment. I have an E3 license, so I should be alble to create one. I need it to create an external list from an Azure SQL DB.
In Sharepoint designer, the button for a new ECT is available, but if I click the button nothing happens. I have an SSS-object with the credentials already.
I do not know why the button is not reacting. Hope someone knows.

Make Sure you have done all these steps before you start creating an external content type..
Prepare SQL Server   A database administrator needs to provide permissions to make sure that that the right people have access to the data and that the data does not end up in the wrong hands. The database administrator must also
create a SQL Server account that has db_owner permission. The database administrator might also want to create specific tables, views, queries, column aliases, and so on to limit the results to just what is needed and to help improve performance.
Configure SharePoint services   An administrator must activate Business Connectivity Services (BCS) and the Secure Store Service.
Configure the Secure Store service   An administrator must determine the best access mode for the external data source, create a target application, and set the credentials for the target application.
Configure Business Data Connectivity Services   An administrator must make sure that the user who creates the external content type has permission to the Business Data Connectivity (BDC) metadata store and that appropriate users
have access to the external content type on which the external list is based.
Be sure Office 2013 is ready to use   To synchronize external data with Office 2013 products, you must use Windows 7 or a later version, and make sure that the Office installation option for Business Connectivity Services (BCS) is
enabled (this is the default). This option installs the Business Connectivity Services Client Runtime which does the following: caches and synchronizes with external data, maps business data to external content types, displays the external item picker in Office
products, and runs custom solutions inside Office products. You must also have SQL Server Compact 4.0, .NET Framework 4, and WCF Data Services 5.0 for OData V3 on each client computer (If necessary, you are automatically prompted to download the software).

How do I scrape external content using a URLScraper channel through a proxy that requires authentication?

I need to scrape external content but my Portal Server lies in my Intranet. The company has a Proxy server that needs authentication in order to browse the Internet.
In the gateway settings, I have made the entries:
iplanet.com|
* Proxyip:proxyport|
This works in the sense that the gateway contacts the proxy for the content, but I get the Proxy Authentication failed page.
Where do I pass my username and password?
Regards,
Vibha

At the present time, you cannot use URLScraper with proxies that require authentication. You can either reconfigure the proxy to not require authentication when accessed by the portal, or create your own custom provider to pass proxy authentication information in the HTTP header.

403 Forbidden Error while trying to access External SharePoint site in SP 2010

I am trying to access external Claims based SP site and trying to download the file from a doc library.
I am receiving the 403 Forbidden error when executing the code.
I am using SP 2010 and Client Object Model.
PFB the code I am running.
using (SPCOM.ClientContext clientContext = ClaimClientContext.GetAuthenticatedContext(siteURL))
if (clientContext != null)
clientContext.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
clientContext.Load(clientContext.Web);
clientContext.ExecuteQuery();
SPCOM.Web web = clientContext.Web;
clientContext.Load(web);
clientContext.ExecuteQuery();
using (SPCOM.FileInformation fInfo = SPCOM.File.OpenBinaryDirect(clientContext, item["FileRef"].ToString()))
string fileName = (string)item["FileRef"];
fileName = string.Concat(SaveLocation, fileName.Substring(fileName.LastIndexOf("/") + 1));
//now save it
using (System.IO.FileStream outPutFile = System.IO.File.OpenWrite(fileName))
fInfo.Stream.CopyTo(outPutFile);
fInfo.Stream.Close();
I suspect the OpenBinaryDirect method ,
I am also using Cookie based authentication I guess PFB the code for that.
public static ClientContext GetAuthenticatedContext(string targetSiteUrl)
return (GetAuthenticatedContext(targetSiteUrl, 0, 0));
/// <summary>
/// This method will return a ClientContext object with the authentication cookie set.
/// The ClientContext should be disposed of as any other IDisposable
/// </summary>
/// <param name="targetSiteUrl"></param>
/// <returns></returns>
public static ClientContext GetAuthenticatedContext(string targetSiteUrl, int popUpWidth, int popUpHeight)
CookieCollection cookies = null;
cookies = ClaimClientContext.GetAuthenticatedCookies(targetSiteUrl, popUpWidth, popUpHeight);
if (cookies == null) return null;
ClientContext context = new ClientContext(targetSiteUrl);
try
context.ExecutingWebRequest += delegate(object sender, WebRequestEventArgs e)
e.WebRequestExecutor.WebRequest.CookieContainer = new CookieContainer();
foreach (Cookie cookie in cookies)
e.WebRequestExecutor.WebRequest.CookieContainer.Add(cookie);
catch
if (context != null) context.Dispose();
throw;
return context;
If anyone has an idea of why is this happening, pls help me.
Thanks,
K.V.N.PAVAN

Hi,
Please try to add following line of code before you initialize cookie container.
e.WebRequestExecutor.WebRequest.UserAgent = “Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)”;
http://razirais.wordpress.com/2011/05/19/how-to-fix-sharepoint-online-403-forbidden-error-while-downloading-files-using-client-object-model/
Or change the following line of code
clientContext.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
to
clientContext.Credentials=new NetworkCredential("Username", "Passworkd", "Domain");

Get "An Error occurred while retrieving data From ProjectWebApp.." when searching content on an External Content Type

I have set-up an ECT in SPD2013 on SP2013. It is a SQL Data source called ProjectWebApp. I have BCS/SSS set-up. I can create an ECT OK in SPD. I can add the ECT to a custom list.
The problem is when I add a new item in the list the following error message appears in red
An error occurred while retrieving data from ProjectWebApp. Administrators, see the server log for more information
I cannot filter or return any results. There is data in the DB.
Another test I do is to try and create a new App/List using the "External List" template. When
I select the ECT a red message appears "External Content Types are not available". which is odd since I can add an ECT to a list as mentioned above.
Any ideas?
