OK, not to beat a dead horse here but.... I used tcpdump to watch the traffic going back and forth between my java program and the jetty server. So here's what my java sends:
GET /bumbleverse/load/object HTTP/1.1 User-Agent: Java/1.6.0_17 Host: localhost:8888 Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2 Connection: keep-alive The server responds: HTTP/1.1 404 Not Found Content-Type: text/html; charset=iso-8859-1 Cache-Control: must-revalidate,no-cache,no-store Content-Length: 1388 Server: Jetty(6.1.x) <html> [redacted error message in html that says NOT FOUND] ... </br> OK fine so you're thinking, well he must have the URL wrong. Well, I opened up good old telnet and pasted in the headers that the java program had sent (just cut and paste out of the terminal). >telnet localhost 8888 Connected to localhost. Escape character is '^]'. GET /bumbleverse/load/object HTTP/1.1 User-Agent: Java/1.6.0_17 Host: localhost:8888 Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2 Connection: keep-alive HTTP/1.1 200 OK Content-Type: text/plain; charset=iso-8859-1 Content-Length: 101 Server: Jetty(6.1.x) [followed by the expected text output] Thanks for any help/ideas...
