HttpURLConnection and java.io.InterruptedIOException

Question

Hello,
I am experiencing the following problem:
I created a standalone java program to open an HttpURLConnection to
an image on the internet at an https address. I am timing how long
it takes to read image through the stream so I can get an idea of my
connection speed.
It works ok, so I made it a servlet that resides in WebSphere 3.5 App server, and when I invoke it, I get:
java.io.InterruptedIOException: Operation timed out: no further information
I check the field java.io.InterruptedIOException.bytesTransferred and it is 0.
Here is a code snippet:
URL dhServlet = new URL("https://www.some-server.com/some-image.bmp");
HttpURLConnection conn = (HttpURLConnection) dhServlet.openConnection();
conn.setDoOutput(false);
conn.setDoInput(true);
conn.setRequestProperty("Accept-Language","en");
conn.setRequestProperty("Accept", "image/bmp, */*");
if (conn.getResponseCode() == 200) // success
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
int chr = in.read();
while( chr != -1 )
chr = in.read();
in.close();
Again, I am confused why it would work in void main but not as a servlet... Thanks for any help you can offer!

No they were on different machines -
so I put the stand alone on on the server with the servlet, and
got the error message:
Exception in thread "main" java.net.NoRouteToHostException: Operation timed out:
no further information
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(Unknown Source)
at java.net.PlainSocketImpl.connectToAddress(Unknown Source)
at java.net.PlainSocketImpl.connect(Unknown Source)
at java.net.HttpURLConnection.getResponseCode(Unknown Source)
at TimeConnection.main(TimeConnection.java:43)
And Line 43 says
if (conn.getResponseCode() == 200) // success
Maybe the server I connect to restricts by IP? Thanks very
much for your feedback!
