connection reset by peer
Hello, I'm using tomcat5.5.23 on a Fedora 5 kernel: 2.6.20-1.2320.fc5. I redirect port 80 to 8080 by running by root: iptables -t nat -A OUTPUT -d localhost -p tcp --dport 80 -j REDIRECT --to-ports 8080 iptables -t nat -A PREROUTING -p tcp --dport 80 -i eth0 -j REDIRECT --to-port 8080 Sometimes (quite often) I get connection reset by peer, in the middle of page loading. It looks like that when running wget (although it happens also using firefox and ie): Connecting to ard.huji.ac.il|132.64.50.50|:80... connected. HTTP request sent, awaiting response... 200 OK Length: unspecified [text/html] 0% [ ] 2,555 --.--K/s 23:43:29 (169.02 KB/s) - Read error at byte 271959 (Connection reset by peer).Retrying. it happens each time in a different stage of the page download. It happens mainly (or only) on large pages (~45 bytes). the server is inside inside a firewall, the error occurs when trying to access it from outside the firewall, I couldn't reproduce the error from inside the firewall. Can someone help with that ? Yair. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
How do I get the response status code?
Hello, I'm trying to create a filter that will do the access logging for my web application (I would like to write the information directly to the database not to a file). I have a problem to get the status code of the response. The filter receives a ServletResponse object that do not have a getStatus() method. Any idea ?

Re: How do I get the response status code?
Hi Brantley,
Thanks for replying.
I've tried to pass a wrapper to the filter's chain, here is the
wrapper's code:
import java.io.IOException;
import javax.servlet.http.*;
public class TestResponse extends HttpServletResponseWrapper {
private int statusCode;
public TestResponse(HttpServletResponse response) {
super(response);
}
public int getStatus() {
return statusCode;
}
public void sendError(int errorCode) throws IOException {
this.statusCode = errorCode;
super.sendError(errorCode);
}
public void sendError(int errorCode, String errorMessage) throws
IOException {
this.statusCode = errorCode;
super.sendError(errorCode, errorMessage);
}
public void setStatus(int statusCode) {
this.statusCode = statusCode;
super.setStatus(statusCode);
}
}
I hopped tomcat will use the wrapper's setStatus() method and then I
will be able to get the status code.
What actually happened is that sometimes the status code returned was 0
and sometimes 404 or 304. It seems tomcat used the wrapper's setStatus()
method only in part of the cases (maybe only when there was a problem
getting the page).
How does the byte count gives information on the status code ?
How do you get the byte count from the output stream ?

Yair,
I too would be interested in this. I wrote a logging filter that does
what you describe, but the best that I could come up with was a
response wrapper that was passed along the filter chain. In the
wrapper, I could set a status, thus guaranteeing that I would end up
with a status at the end. The wrapper extends
HttpServletResponseWrapper.
You may also find a wrapper useful because response sizes are not
always set either, at least in my experience. With the wrapper, you
can monitor the output stream to get a byte count.

Re: How do I get the response status code?
Well, it does, partially.
I sometimes get a non zero status code, but it's not zero only when
there is an error (status code s: 404, 304).

Ahh.please ignore my last.
I see that you're doing the same thing I mentioned (setting a private
variable and returning that as the status).
Is this not working for you?

Reloading shared classes
Hello, I'm using tomcat 5.0.28 on a Linux machine. My web applications are using some shared class. I put them under $CATALINA_HOME/shared/classes. The problem: When I make changes in the shared classes, restarting a web application by tomcat's manager is not enough for the changes to be reloaded. Only the tomcat server shutdown + start cause the changes to be reloaded. How do I configure the web application or tomcat to reload the shared classes when restarting the web application?

Re: Reloading shared classes
You are right, I've just wanted to avoid multiple copies of the same classes. They are not really shared. If the classes are shared, all the web applications should be restarted, because the change affect all of them. Yair.

To reload those classes, you'd have to reload the contents of the shared classloader - which you can't do without restarting all the other webapps. Any other approach removes the need for the *shared* classes. Do the classes genuinely need to be shared between the webapps, or are you doing this to save space? - Peter - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: configuring Tomcat for protocols other than http/s
Is there anything more about this, other than the (very poor) javadocs, or is the only option is looking in the code? Viraj Turakhia [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi all, I am starting to work with Tomcat's code and have no clue where to start from. Any pointers would be very very helpful. Well, one method is to implement your own ProtocolHandler ( http://tomcat.apache.org/tomcat-5.5-doc/catalina/docs/api/org/apache/coyote/ProtocolHandler.html). This is responsible for setting up the Request and Response objects, threading, and handling sending and receiving data on the protocol. It then hands off the Request and Response to the service method of the Adapter (http://tomcat.apache.org/tomcat-5.5-doc/catalina/docs/api/org/apache/coyote/Adapter.html) that Tomcat passed to it. The MemoryProtocolHandler (http://tomcat.apache.org/tomcat-5.5-doc/catalina/docs/api/org/apache/coyote/memory/MemoryProtocolHandler.html) is the easiest if you want an example. You'll probably also want to implement ActionHook (http://tomcat.apache.org/tomcat-5.5-doc/catalina/docs/api/org/apache/coyote/ActionHook.html) for best results. You tell Tomcat to use yours via: Connector protocol=com.myfirm.mypackage.MyProtocolHandler / To start with, I would like to know whether Tomcat is configurable to work with protocols other than http/https? Well, it comes with AJP/1.3 support ;-). However, the servlet container neutral to the protocol (that's the job of the ProtocolHandler :). I want to configure Tomcat in such a way that it gives me RAW data that is posted on given port. Please let me know which server element is to be configured (and where.. server.xml?) such that forming request/response from RAW data is possible for me. This RAW data is not necessarily a http/https specific data. It could be specific to any other protocol like ftp://.

images
Hi, I have a servlet that transforms an XML using XSLT. In the result HTML I want to include some images. Where do I place those images? I tried the WebContent directory, but they could not be loaded (I even tried getting them explicitly, but the servlet was invoked instead).

Re: password protection
Thank you again, I've set a security-constraint on the context (in the web.xml), and it works OK now. What I'd like to know is: 1. Can I do it anywhere else other than the web.xml, so that the deployer can control this and not the developer? 2. Can I set it for a group of contexts, so that they will all be able to use request.getPricipal() and have the user name that logged in? - Original Message - From: David Delbecq [EMAIL PROTECTED] To: Tomcat Users List users@tomcat.apache.org Sent: Wednesday, February 15, 2006 3:05 PM Subject: Re: password protection http://www.onjava.com/pub/a/onjava/2001/07/24/tomcat.html http://www.cafesoft.com/products/cams/tomcat-security.html for other ones, use favorite search engine.

distribution
Hello, I've used tomcat to run some naive servlets, and now I need to do something more complicated. I need to be able to distribute my service. Clients connect to a tomcat server and their requests are forwarded to a backend server. I need to be able to distribute all this, so that clients can connect to any of a number of tomcat servers and then be directed to the same backend server throughout their session (until they log out). Can anyone point me to where I can read about such a solution? What I thought was maintaining a database with a mapping of session - backend server, and use it, but this requires querying the database for each transaction... Any other ideas?] Thanks, Zohar. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: distribution
The requests from the client are made in distinct sessions. For each request a new HTTP session may be created, but it would still need it to be directed to the same tomcat (and to the same backend server) that handles it. The session is identified with an HTTP header or an attribute in the request's body (not sure yet). I guess I have an application-level session that may encompass many HTTP sessions. Any way of doing this? Thanks, Zohar. - Original Message - From: Richard Mixon [EMAIL PROTECTED] To: 'Tomcat Users List' users@tomcat.apache.org Sent: Sunday, January 08, 2006 5:55 PM Subject: RE: distribution Zohar, Not exactly clear on your requirements. Do you care which backend server the client is initially redirected to? If not, then you can use a load balancer that supports session affinity. It will use a load-balancing algorithm to initially decide which back-end server to forward a particular client to. Afterwards it will redirect all requests from the same client to the same backend server - until the session times out, which is configurable usually). You can of course use a dedicated load-balancing appliance to do this. Current versions of Tomcat also ship with a load-balancing application application that might work for you. However a lot of people use the Apache web server with its associated mod_jk module to perform this function. I have used it a year and it works fine for this. Here is the doc on the mod_jk connector: http://tomcat.apache.org/connectors-doc/index.html Here is the tomcat load balancer doc: http://tomcat.apache.org/tomcat-5.5-doc/balancer-howto.html You should also search the archives for this mailing list, there have been many posts in the past on this topic: http://marc.theaimsgroup.com/?l=tomcat-userr=1w=2 HTH - Richard -Original Message- From: Zohar Amir [mailto:[EMAIL PROTECTED] Sent: Sunday, January 08, 2006 6:03 AM To: Tomcat Users List Subject: distribution Hello, I've used tomcat to run some naive servlets, and now I need to do something more complicated.

NPE in init()
Hello, I'm new here, so all the normal disclaimers... I wrote a servlet and needed to read some configuration, so I overrode init(ServletConfig config). I forgot to invoke super(config) and then tried invoking getServletContext() and got a NPE. It took me some (a lot actually) time to figure out why... My question is why can't a descriptive exception be thrown when invoking anything that presumes that config is set? I refer to GenericServlet, where a few methods rely on getServletConfig() to return a non-null value, and act on it. TMHO the return value should be checked and a descriptive exception be thrown (servlet should be initialized or whatever), instead of the NPE.
