svn commit: r685509 - /cocoon/trunk/core/cocoon-servlet-service/cocoon-servlet-service-components/src/main/java/org/apache/cocoon/servletservice/components/ServletSource.java

New Revision: 685509

URL: http://svn.apache.org/viewvc?rev=685509&view=rev
Log:
Implemented exists() method so it tries to return more meaningful value.

Also, use exists() method in getInputStream, if it does not exist then SourceNotFound exception should be thrown.
