Hi Sudipto,

The error message is truncated, so we can't really see the root cause. Maybe you can print it fully.

The first thing that comes to my mind however is that the com.internal.servlet.MainControllerServlet depends on classes which reside in a library. That library is either present in a different application or is deployed separately on the Engine.

If so, then you need to check the references defined from the application which hosts the servlet to the application/library which hosts the classes required for the servlet.

The library definitions are in the <server>\managers\library.txt file.

The reference definitions are in the <server>\managers\reference.txt file.

You can manupulate the above files from telnet shell using the changelib and changeref commands.

Normally you would define the libraries and references first and then deploy the application that uses them.

I hope the above is helpful.

Best Regards,

Iavor
