Solution:

I researched a lot on net but couldn't succeed. I opened the IIS and expanded the webapplication on which I am getting an error. It found that there no commerce server specific files and folder. Like “PtipeLines” folder and “MetadataDefinitions.xml, OrderObjectMappings.xml, OrderPipelineMappings.xml, ChannelConfiguration.config” files. I put the folder and all folders in place, given the appropriate permissions. Recycled the apppool of my web application and refresh the site but couldn't succeed. Event Viewer is filled with this exception.

After I have opened the web.config file and verified. I have found that commerce server related entries in <httpModules>sections are missing. Following are the missing entries:

I have added the given entries in <httpModules> section and site is working fine and I am happy J
