Description
A custom extension developed may fail to deploy on the Spotfire Server, throwing an internal server error in the Administration UI, if it is not signed with a strong name key. In such cases the "PublicKeyToken=null" is the problem.
ERROR 2017-02-20T16:50:41,563-0800 [sp65svc1@1tsspa.lab, #107] ws.deployments.GwtDeploymentServlet: Internal Server Error a96618ad-a265-4f54-b295-aa6e87b45f68: The value 'SpotfireDeveloper.HtmlPrintToolExampleForms, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not a valid AssemblyName.java.lang.IllegalArgumentException: The value 'SpotfireDeveloper.HtmlPrintToolExampleForms, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not a valid AssemblyName.
The corresponding error in the Spotfire server log would be something like the following.
ERROR 2017-02-20T16:50:41,563-0800 [sp65svc1@1tsspa.lab, #107] ws.deployments.GwtDeploymentServlet: Internal Server Error a96618ad-a265-4f54-b295-aa6e87b45f68: The value 'SpotfireDeveloper.HtmlPrintToolExampleForms, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not a valid AssemblyName.java.lang.IllegalArgumentException: The value 'SpotfireDeveloper.HtmlPrintToolExampleForms, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not a valid AssemblyName.
Issue/Introduction
This article explains how to resolve the error "not a valid AssemblyName" when deploying a custom extension on the Tibco Spotfire Server.
Resolution
Custom extensions need to be signed in Visual Studio before creating the SPK file. To sign the Custom Extension via Visual Studio, browse to the "Project Properties - Signing" - Select the checkbox to Sign the Assembly - Create a new key to sign the file or use an existing one.
Alternatively the Assembly can also be signed in the Package Builder after adding the extension. Right click the Extension - select Package Signing Options to select the required key to sign the package.
Note: There is a SpotfireDeveloper.snk file (Visual Studio Strong Name Key File) available in the TIBCO Spotfire Developer package SDK/Examples/Extensions folder which can also be used to sign the assembly.
