Hi
i am getting an error like this
*java.lang.ClassCastException*: com.iton.uima.TestTypestep :5
at com.iton.uima.Clases.ExampleApplication.processFile(*
ExampleApplication.java:169*)
at com.iton.uima.Clases.ExampleApplication.testAnnotation(*
ExampleApplication.java:99*)
at com.iton.uima.Clases.ExampleApplication.main(*ExampleApplication.java:33*)
it is showing error at these lines
DocumentAnnotation annot = (DocumentAnnotation)itr.next();
*
processFile*(files[i], ae, cas, out);
*i have tried to use TestType which is defined in document descriptor but
same error is repeting.here i am getting out put then this error is coming
along with it*
*can any one help me in this*
*vijay*
