The Analytica Decision Engine (ADE) is sold as a separate product from Analytica. It allows you to make use of an Analytica model from the backend of a custom application, such as one written in a programming language like a Visual Basic, or from an web application using a technology such as Active Server Pages (ASP).

Using ADE from Java

The Analytica Decision Engine (ADE) exposes the full functionality of the Analyica Decision Engine with COM and ActiveX Automation programming interfaces (APIs). Calling ADE from a Java program requires a third-party component called a Java-to-COM bridge. There are several such products on the market, such as [http:www.ezjcom.com EZ JCom], [http:j-integra.intrinsync.com J-Integra], [http:www.nevaobject.com Java2Com], [http:danadler.com/jacob JACOB], [http:www.alphaworks.ibm.com/tech/bridge2java Interface Tool for Java], [http:www.jniwrapper.com Comfyj], and many others. Lumina does not have a recommendation on which bridge to use.

Cannot instantiate an ADE instance through IIS in an ASP.net application

The following exception is encountered when attempting to create an instance of ADE in an ASP.NET application, however, I can launch ADE (e.g., using AdeTest) from my user account just fine.

Exception Details: System.UnauthorizedAccessException: Retrieving the COM class factory for component with CLSID {C1D8F050-CD44-11D1-AEA4-0040054234B1} failed due to the following error: 80070005.

IIS launches COM objects through a special account. This exception is encountered when this special account does not have the required permissions (Local Launch and Local Activation) to create an instance of ADE. The accounts used by different versions of IIS is given below:

IIS 5: {Computer Name}\ASPNET

IIS 6 and 7: NETWORKSERVICE (identity) or IIS_IUSRS (user)

IIS 7.5: ApplicationPoolIdentity (identity)  or IIS AppPool\DefaultAppPool (user)

Setting the permission for the special account

  1. Launch: Start→Administrative Tools→Component Services→My Computer→DCOM Config
    • Note: If you are running ADE 32-Bit on a Windows 64-Bit machine run the command Start > Run > 'mmc comexp.msc /32'
  2. Right click on Analytica Decision Engine Local Server 4.4, select Properties→Security
  3. Click Launch and Activate Permissions→ Customize → Edit...
  4. Add... the appropriate account depending on your version of IIS.
  5. For this account, check Local Launch and Local Activation permissions
  6. Click OK or Apply to save the permission changes.
