I meet a strange problem in Weblogic6.1. I map "http://hostname/abc" to "http://hostname/abc/file.jsp". And in file.jsp I use forward method " ". Then when I access url "http://hostname/abc" by client, exception occurs as following:

"javax.servlet.ServletException: no request dispatcher vailable for 'ther.jsp?id=0'"

I seems that ahead three characters have been moved. If I change "abc" to "abcd". Then 'her.jsp?id=0' occurs. Strange thing the length is the same. Anyone can help me resolve this problem. Thanks!
