Class ServletExceptionWrapper

java.lang.Object
  extended by java.lang.Throwable
      extended by org.apache.cactus.internal.client.ServletExceptionWrapper
All Implemented Interfaces:
java.io.Serializable

public class ServletExceptionWrapper
extends java.lang.Throwable

Wrapper around a Throwable object. Whenever an exception occurs in a test case executed on the server side, the text of this exception along with the stack trace as a String are sent back in the HTTP response. This is because some exceptions are not serializable and because the stack trace is implemented as a transient variable by the JDK so it cannot be transported in the response. However, we need to send a real exception object to JUnit so that the exception stack trace will be printed in the JUnit console. This class does this by being a Throwable and overloading the printStackTrace() methods to print a text stack trace.
