Issue with IwebContextAdapet api after upgrade to EP 7.0

Hi All,

We are finished with upgrading to EP7.0 . Some web dynpro applications are not working after upgrade .

They are showing error with IwebContextAdapter api as below :

java.lang.ClassNotFoundException: com.sap.tc.webdynpro.services.sal.adapter.core.IWebContextAdapter Found in negative cache -

It seems IwebCOntextAdapter api is noty available after upgrade. Can anyone suggest me how this error could be ressolved.
