Custom Payment Gateway from App_Code returning an error

Lukas Filim asked on March 3, 2014 04:15

Hi,

I've been working on creating my own custom payment gateway and I have used code and the video from here - http://devnet.kentico.com/articles/developing-custom-payment-gateway

My custom provider is always returning an error in th event logs sames as World Pay code from above link: Message: Could not load file or assembly 'CMS RealexProvider' or one of its dependencies. The system cannot find the file specified. Stack Trace: at System.Reflection.RuntimeAssembly._nLoad(AssemblyName fileName, String codeBase, Evidence assemblySecurity, RuntimeAssembly locationHint, StackCrawlMark& stackMark, IntPtr pPrivHostBinder, Boolean throwOnFileNotFound, Boolean forIntrospection, Boolean suppressSecurityChecks) at System.Reflection.RuntimeAssembly.InternalLoadAssemblyName(AssemblyName assemblyRef, Evidence assemblySecurity, RuntimeAssembly reqAssembly, StackCrawlMark& stackMark, IntPtr pPrivHostBinder, Boolean throwOnFileNotFound, Boolean forIntrospection, Boolean suppressSecurityChecks) at System.Reflection.RuntimeAssembly.InternalLoad(String assemblyString, Evidence assemblySecurity, StackCrawlMark& stackMark, IntPtr pPrivHostBinder, Boolean forIntrospection) at System.Reflection.RuntimeAssembly.InternalLoad(String assemblyString, Evidence assemblySecurity, StackCrawlMark& stackMark, Boolean forIntrospection) at System.Reflection.Assembly.Load(String assemblyString) at CMS.SettingsProvider.ClassHelper.GetAssemblyInternal(String assemblyName) at CMS.SettingsProvider.ClassHelper.GetClassInternal(String assemblyName, String className) at CMS.EcommerceProvider.CMSPaymentGatewayProvider.GetPaymentGatewayProvider(Int32 paymentOptionId)

I'm using Kention 7.0 and can't much of a help to get thru this error.

Best Regards, Lukas

Hi,

Sorry above error started to occur when I wanted to implement the gatewat not from App_Code folder , proper error that is logged in teh event log for App_Code payment gateway is : Message: [ClasHelper.GetClass]: App_Code class cannot be loaded because the OnGetCustomClass handler is not initialized. Stack Trace: at CMS.SettingsProvider.ClassHelper.GetClassInternal(String assemblyName, String className) at CMS.EcommerceProvider.CMSPaymentGatewayProvider.GetPaymentGatewayProvider(Int32 paymentOptionId)

OnGetCustomClass handler for me is initailized in loader class hacing correct code same as WorldPay in the sample link in first post.

Best Regards, Lukas

Hi,

For anyone else who may have the same problem, we were able to resolve Lukas's the issue via email. The cause of the problem was using a WebApplication and not a WebProject. When using WebApplication, the .NET framework does not use App_Code folder, therefore Kentico has to use its own alternative, called Old_App_Code. To fix your issue, do the following:

  1. Move all contents of the App_Code directory to Old_App_Code,
  2. Rremove App_Code
  3. Include the moved folder in the Solution
  4. Clean and build the Solution
  5. Clear browser cache and try the checkout again.
