Error in sender channel:

Question

When activating changes in  IR I used to get system message as NoClassDefFoundError.Even then the componenets used to get activated.
Initially every thing was working fine with the sender channel.
It was successfully picking up the file and sending the same to receiver channel.
Suddenly after a day I sarted getting this error (below).And the file was not getting picked up.
<b>Error in channel</b>Error: javax.ejb.TransactionRolledbackLocalException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/sap/aii/af/app/mp/impl/ModuleProcessorCategories; nested exception is: javax.ejb.EJBTransactionRolledbackException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/sap/aii/af/app/mp/impl/ModuleProcessorCategories

There was no such error: And I had not made any changes since it was working fine.
Is this error because of the message I used to get in IR.?Was might be the cause

Hi,
Please check you message first properly all conditions supporting or not.Is message is having any exceptional chars , and Check whether your are using Async or Synch communication , respectivly the sender and receiver  communication mode supporting both sides. and check your J2EE is working fine or not, Check your interface is having the module processors in sender side/receiver side is yes , those are working fine or not , those are properly imported properly or not.
these diffects may not effect the activation of components.
Also check your receiver Business system is working fine or not
And also check your receiver agreement is configured,receiver determination and interface determination all are refered same business systems or not.
,please see the following threads
