I'm trying to use Velocity as a session state manager and getting the following exception

Question

Hi,

 

I'm trying to use Velocity as a session state manager and getting the following exception:

 

Line 47: <sessionState cookieless="false" regenerateExpiredSessionId="true" mode="Custom" customProvider="Velocity"> Line 48: <providers> Line 49: <add name="Velocity" type="System.Data.Caching.SessionStoreProvider"/> Line 50: </providers> Line 51: </sessionState>

 

web.config:

 

<sessionState cookieless="false" regenerateExpiredSessionId="true" mode="Custom" customProvider="Velocity">

<providers>

<add name="Velocity" type="System.Data.Caching.SessionStoreProvider"/>

</providers>

</sessionState>

 

Are there any examples on how to set it up to be used as session state manager?

 

Regards,

Alexei

Answer 1

Sorry, forgot to include the exception message:

 

Parser Error Message: The type initializer for 'System.Fabric.Common.EventLogWriter' threw an exception.

Source Error:

 

Answer 2

Here is a blog article that describes how to do this.

We will also soon blog more details on the Velocity Blog

 

Answer 3

Can you share more of your configuration file (web.config) ??

 

Answer 4

There might be some issues with the <web.config> file. You may use "web.config" with following contents:

 

<?xml version="1.0"?>

<configuration>

            <configSections>

                <section name="dcacheClient" type=" System.Configuration.IgnoreSectionHandler"

                  allowLocation="true" allowDefinition="Everywhere"/>

            </configSections>

     

<dcacheClient deployment="simple" localCache="false">

                  <hosts>

                  <!--List of hosts -->

                  <host name="<serviceHostName>" cachePort="22233" cacheHostName="DistributedCacheService"/>

                  </hosts>

            </dcacheClient>

<system.web>

<sessionState  mode="Custom" customProvider="SessionStoreProvider">

<providers>

                                                                <add name="SessionStoreProvider" type="System.Data.Caching.SessionStoreProvider, ClientLibrary"/>

                                                </providers>

                                                </sessionState>

</system.web>

</configuration>

 

Replace <serviceHostName> with the hostname of machine your cache service is running, By default service uses  port no:  22233, modify "cachePort" if different port is used. Tomarrow, we will also be posting a detailed blog post about how to use session store provider shipped with the product at product blog.

Let's us know if you still face the problem.

Answer 6

 

Replace this section entry in <confgSections>

 

<section name="fabric" type="System.Fabric.Common.ConfigFile, FabricCommon, Culture=neutral, PublicKeyToken=null" allowLocation="true" allowDefinition="Everywhere"/>

 

with

 

<section name="fabric" type="System.Fabric.Common.ConfigFile, FabricCommon" allowLocation="true" allowDefinition="Everywhere"/>

 

And your application should work fine. Actually FabricCommon is a strong-named assembly.

Duh!

 

It fixed it. Thank you for the help. I think I copied this code from the doc so you might want to check it to make sure that it is corrected there as well.
