AW: Shutdown hook for correctly unloading drivers
Hi How does tomcat unload classes? It doesn't, at least not directly. Tomcat simply eliminates all references to the classes; the actual unloading is done by GC at some point in the future. Is there even a way in java to do this? Just the above. But making the classes unreachable should be adequate for whatever purpose you have in mind. This does not hold, as soon as Threads are involved, right? Regards, Steffen smime.p7s Description: S/MIME cryptographic signature
Re: tomcat PUT not working
Kumar Kadiyala wrote: Chris, I see the content when I read the InputStream. Thanks for your help. Hi. It seems that you are helped, and that is the essential part. Maybe to balance a bit with the subject of your post (Tomcat PUT not working), I just want to provide some additional information here, as to why what is happening is happening, and maybe stress that this is not a case of PUT not working. It is working as it should; it just happens that it is not maybe how you expected it to work. Much of what follows is already included in the thread which you mentioned earlier, but that thread was a bit stressed at times due to the vocabulary and tone of the original poster, so here is a summary : Tomcat is at the same time a Servlet Engine and a HTTP server. For Servlet Engines, the official reference is the Java Servlet Specification. For the HTTP protocol, the official reference is RFC2616. Tomcat tries to respect both of these specifications when applicable. REST is not an Internet protocol. It is an application layer, built on top of HTTP (or on top of another protocol). Tomcat is a not a REST server, and does not pretend to be. You can build a REST application on top of Tomcat, but it is the job of that REST application then, to handle the aspects that are specific to REST and are not part of the HTTP protocol or of the Servlet Spec. The area of contention here is whether a HTTP PUT request can or not have parameters, and whether such parameters can or not be encoded as part of the HTTP body of a PUT request (or as part of the URL query string of the request). For GET and POST requests, both the HTTP RFC and the Servlet Spec provide some answers and describe how it is done. Basically (and roughly), - for a GET (which does not have a body), such request parameters are encoded as part of the request URL query string part - for a POST request (which has a body), the parameters are encoded the same way, but are contained in the HTTP body of the request. In both cases, Tomcat allows an application to retrieve these parameters via calls like HttpServletRequest.getParameters(). These calls automatically decode and parse the request parameters and return them to the application in a neatly usable format. For a POST request, you are also free to read the request body yourself, and then parse the parameters yourself. For PUT requests however, there is no mention anywhere (in the applicable specs) of parameters. In fact, the HTTP RFC definition of a PUT request seems to indicate that the body contains the resource that the client wants the server to store at the location corresponding to the indicated request URL. The best example of that is probably the DAV application (available as an add-on application under both Tomcat and Apache httpd), which allows a client to upload files to the server at a specific location, so that these files can then later be retrieved (via for example a GET request) using the same URL as the one used for the upload. (So basically, it is not that parameters are forbidden for a PUT; it is just that they are not mentioned). For all these reasons, currently Tomcat does not support the getParameters() family of methods, when the request method is PUT. It is possible that other servlet engines support this, but in that case it has to be considered as an optional add-on, not as something that is required by the HTTP RFC nor the Servlet Spec. I believe that because of that previous thread, a request for enhancement was filed to ask the Tomcat developers to provide such support in the future, but I don't know the status of it. But the crux of the matter is, that if a (REST) web application would depend on that feature to be available in an HTTP server or a Servlet Engine, then that application is not portable, because the applicable specifications do not mention this as a mandatory feature of either of them. Reading the PUT request body yourself, and parsing it into parameters yourself, is on the other hand perfectly supported and should work anywhere. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

RE: sticky session failover
Hi Arunkumar, The failover is working. What I need is the tomcat instance to which failover occurs assumes ownership of the sticky session, by that the session id has to be changed to use that tomcat instance's jvmRoute and cookie has to be reset, otherwise it is no longer sticky session since requests for tha session will be sent to ANY of the other tomcat instances configured by load balancing. I believe this transfer of sticky session ownership done by renaming of the session and resetting the cookie is performed by JvmRouteBinderValve which is configured as part of a Cluster configuration. My problem is that I'm not using cluster session replication because my environment doesn't support multicast. I'm using PersistentManager for session persistence using jdbc as mentioned. I don't think it is possible to successfully configure a Cluster in this case (no multicast and using PersistentManager instead of session replication) but a Cluster configuration is required to configure JvmRouteBinderValve. I'm wondering what my options are in this case. Do I have to write my own valve to do what JvmRouteBinderValve does but that works without a cluster configuration? Is my understanding correct?

When inside corporate network, it works. Can you explain how exactly it works ? what URL are you using then, from where ? what are you seeing then ? http://localhost:8080 OR http://127.0.0.1:8080 works in one network (corporate) and the same does not work in a different network (my home network - wireless network for home from T-phone) In home network, it doesn't. Same questions. In my home network, I'm connected to via a router to the internet. The point is that Tomcat is installed locally on my laptop and it should work without any such connectivity. Unfortunately it doesn't. Strange enough that it does not work even when the laptop stands alone (not connected to any network). Accessing http://localhost:8080results in: ERROR_INTERNET_CANNOT_CONNECT as seen with HttpWatch. The request does not reach the server (hence no log). I presume this URL really is : http://localhost:8080/results , right ? That was a formatting mistake. I meant only http://localhost:8080 This request to the local server results in ERROR_INTERNET_CANNOT_CONNECT as seen with HttpWatch. server.xml has not been changed. netstat -ab shows the following processes: TCP0.0.0.0:8009 hostname:0LISTENING [java.exe] TCP0.0.0.0:8080 hostname:0LISTENING [java.exe] : Windows Sockets initialization failed: 5 What does that mean ? What is is in the Tomcat logs, corresponding to this error ? TCP[::]:8009 WDFN00224028A:0LISTENING [java.exe] TCP[::]:8080 WDFN00224028A:0LISTENING [java.exe] Windows host file has the following entries: 127.0.0.1 localhost ::1 localhost Using java version 1.6.0_18 The problem appears to be very strange to me. Did a lot of searching on the web before this post. Nothing helped. I'm sure that this is not a new problem and hoping that one of you have already solved such an issue. Is the Windows firewall or anything similar enabled (AUP or whatever it's called) ? If you do NOT start the Tomcat Service, and do a netstat -ab, what do you see then ? Thank you for helping me on this. The same setup on the same laptop will start working tomorrow when I am connected to corporate network. This is a corporate laptop and windows firewall is installed. But I am not sure where should I look in to check if this firewall is the blocker. Moreover, I may not be allowed to turn this firewall off even if it is required. By the way, i turned it off temporariry (for 5 mins, hope nothing has happened in between) but the situation did not change. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: access to localhost:8080 fails
Chuck: To verify the network issue, I installed Tomcat on my personal laptop. The browser is still unable to show up: http//localhost:8080. I'm connected to a router via a wireless network which in turn connects me to the internet. I have Mcafee antivirus, firewall and spyware installed. I will now look into the problem from this direction as well. Thank you.

Upgrade tomcat 6 to a new point release on windows
Hi, what is the procedure for upgrading to the latest point release of tomcat 6 on windows? We are on 6.0.18 running tomcat as a windows service. What is the recommended procedure for upgrade? Does the current windows installer do the right thing to in-place upgrade 6.0.18 to 6.0.26? Or is this an uninstall, reinstall thing?

Re: access to localhost:8080 fails
I have seen similar issues on our corporate (XP and Vista) laptops, somebody decided that the locally running firewall should also block access to localhost. I think you should first verify if that's the case. I'm not a Windows expert, so I don't know how to check if the above is the case. If you are allowed to give the netstat command, try the suggestion from Charles (netstat -ano), if you see status SYN_SENT, it's for sure a firewall issue. regards, Harry 2010/3/28 Krishanu Biswas biswas.krish...@googlemail.com Chuck: To verify the network issue, I installed Tomcat on my personal laptop.
