Context initialization failed *** No default constructor found;java.lang.NoSuchMethod

[jmalkan]

I am building a proto type using Spring (2.0.6) and Hibernate (3.2). I have 3 beans to start with, An Entity, Manager and a Mapper. I am deploying the WAR on WebLogic. I get the error message indicating that Mapper object has no default constructor while I have a default constructor.

Following is the error from WebLogs console

ERROR 2007-08-01 12:49:30,169 [ContextLoader]: Context initialization failed

Please, post signature of the constuctor(s) of DeviceMapper class
and your context (or, at leasr, definition of the "deviceMapper" bean).

Seems that they do not match.

I found that the problem was that I had another JAR file on my path with DeviceMapper and DeviceManager classes. I also was missing cgilib. After i fixed them it all works fine so far.
