Re: Isapi redirector log file is always empty - IIS 7.5 - Tomcat 7.0.26 - Isapi 1.2.30 - Win2008 R2
ann ramos wrote: Hi, I have set up our system to do SSO. The setup works fine because whenever the user access the system, they are automatically logged in to the system. Following are the steps that I used to set up Isapi: 1. Manually created the folders Apache Software Foundation\Jakarta Isapi Redirector. Then inside those folders I created a sub folder bin, conf and log. 2. I manually created the registry entries. The set up works because the system functions as SSO. The only thing is that my isapi_redirect.log is always empty even though I set the log_level to debug. I tried searching the internet but I'm not getting anywhere. I would appreciate any thoughts and ideas that you can share so I can resolve my problem. Apart from your mention of Tomcat in the subject, it is not very clear so far if anything you're doing is accessing Tomcat through isapi_redirector (or even Tomcat at all). Can you be a bit more explicit about what you are doing ? And where the SSO part come into the picture here ? - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Threads in Tomcat
I'm maintaining a Web application for searching multiple wikis, this app runs under Tomcat 6. I need to modify a servlet so it instantiates a 'Thread' subclass to perform a wiki availability check every so often, say every 30 minutes. Given that I'm no expert on the use of threads, a co-worker suggested the following questions to look into: · Does the spawned thread have a time limit imposed by Tomcat? · Does it take up worker thread space from other Tomcat threads? I'd appreciate any help anyone could give w.r.t. these questions.

Re: Threads in Tomcat
Chris, thanks for responding. The servlet I have in mind for modification is the one responsible for performing the search as well as for getting the next page of search results. If one or more of the wikis is unavailable, I want to display an error message on the search results page. The wiki availability check won't be done all the time, as I mentioned before, just every so often, say, every 30 minutes. Why would using a ServletContextListener be better than using a servlet?

I have /subapp/a and /subapp/b. Can i have different sessions for them?
Hi, first time posting on a mailing list, hope i'm not breaking any rules of some sort. My problem is pretty simple but it seems a lot of people have trouble understanding it in other forums. Let's say i have 2 main entry points into my application: /subapp/a and /subapp/b. They are part of the same webapp but they are somehow different and i want to distinguish between them. Having a separate session for each of them would be the greatest thing but is this possible for Tomcat? The path of the session cookie (JSESSIONID) is automatically put at the root context path (so /subapp in this example). And i don't want to have multiple wars or multiple Tomcats... I would like this in Tomcat 7 btw... I'm trying to avoid changing Tomcat itself so i tried to extend/wrap the usual response classes/interfaces but no luck because Tomcat writes the Set-Cookie header directly into the coyote response header... Any help would be appreciated, been wrestling with this for some days... Thanks, Teo

WebApp on Tomcat recognize automaticely uploaded file
Hello, can anyone help me, if there is a configuration parameter in tomcat, which permit to the web application to auto-recognize when I put an image from filesystem into the webapp? I put images in the path of my application: appBase/webAppA/uploads through another webAppB, but seems that webAppA recognizes the images only after Tomcat restart. Working until now with tomcat integrated into eclipse, I didn't noticed this event because eclipse was publishing automatically after each upload. Thank you to anyone for any kind of help. Ermal

Re: WebApp on Tomcat recognize automaticely uploaded file
Yes, I say webAppA do not recognize the images because do not serve them through the browser via URL. I did the following scneario and writing down in case can make the situation more clear uploaded manualy the following files on: webAppA/uploads/1.jpg webAppB/uploads/1.jpg requesting the files through URL i have the following: www.localhost/webAppA/uploads/1.jpg --- no reply www.localhost/webAppB/uploads/1.jpg -- photo visualized Do you have any idea what might cause appA not to recognize the images?

Tomcat SPDY Connector
Hi! I'm currently experimenting with developing a .Net SPDY Client / IIS SPDY Redirector (written in C#) that could be used as a possible replacement over AJP, to forward HTTP requests from IIS to Tomcat (some time ago I mentioned that I might look into writing such a client when I had some spare time [1] - which is the case now ;) ). It is based on Draft3 of the SPDY specification [2], which names the protocol spdy/3. Currently I'm testing the client with Google servers which support both spdy/2 and spdy/3. I'd also like to test it with Tomcat. I don't know much about Tomcat's code/architecture, but from looking at the SPDY code from Tomcat trunk [3], it seems that Tomcat is currently only supporting spdy/2, but not spdy/3. Is this correct? If yes, are there already plans to implement spdy/3? (The main difference between SPDY v2 and v3 is the addition of flow control, which I think is important when using SPDY as server-to-server protocol, to prevent flooding the intermediate server with messages if it has a slow connection to the actual client.) Thanks!
