Title: RE: Servlet refresh

Yeah, the HTTP server won't write anything to the display until the headers are sent for the client.  When you're telnetting in, you're effectively opening a raw-text socket to the server.  You can then explicitly type in the HTTP headers that you want sent, and when you hit <return> twice, you get the response.  The HTTP protocol describes exactly how a well-formed HTTP header must be created: you just have to manually create it by typing in the right values.  Take a look at the HTTP/1.1 RFC over at www.ietf.org for the full specification of what is and is not allowed.

Hi chris,
I am trying to use the telnet as per your advice.
When you say "servername". I am using the "localhost"
On the command prompt  I type "telnet localhost : 80" 
when I do this, I get a blank screen.  I then have to enter twice before I see some HTML data.
Am I doing right here?

If at first something like that doesn't work for me, I tend to stop Tomcat,
erase the offending servlet, copy the new version in again, and restart.
However, it sounds like you've probably already done this.  The next thing I
would try is to just make absolutely sure the browser isn't serving you a
cached copy.  The best way to test this is to telnet to your HTTP server:

telnet servername 80
GET /absolute/url/to/servlet HTTP/1.1
Host: localhost

(make sure you hit return twice after the Host: line).  The response you get
in the telnet window will be exactly what the server is sending.

If you get the "new" version response from that command, then it's the
browser at fault; otherwise, it's Tomcat.

Yes I did. I deleted all the cache from the browser too.

Thanks

Have you emptied the browser cache/shift-reloaded the page?

Hello:

I am running TomCat 4.0.1 and I have servlet class file placed in the
appropriate position.

I made some changes ot my servlet source class and compiled. Compilation
went thorugh. I restarted my TomCat server. But still, I do not see the
changes. I have changed hte text to be displayed. I am not able to see the
change in the browser.

Where am I going wrong?

Thanks in advance.
