java.lang.NoClassDefFoundError: while starting Integration Builder!

Hello experts,

I was working on IR absolutely fine. The connection went off and I tried to log in to IB again. It gave me locking error when I was trying to edit any object. So the BASIS guy stopped the XI server and tried to make it up again.

After that when I am trying to open Integration builder, its giving me the following error:

"Message

Neither me nor my BASIS guy are having any idea why this error is comming all of a sudden when everything was working absolutely fine.

Can anyone please help me in resolving this issue as this is very critical?

Thanks in advance.
