On the tomcat server in server.xml, one instance is running on port 8009 and the 2nd instance (in another directory structure) is running on 7009. On the apache server in httpd.conf, I have the following: Listen 80 . . .

However, both instances have apps that start with tsa. How do I configure the apache webserver to service the tsa app for both tomcat instances? configure a load balancer (worker) that uses the (other) two workers, in addition to the two workers, and add it to the worker list. I think that rather than be added to the workers list, the load-balancer worker must be the only one in the list. You then tell the balancer to balance the two other workers. Then the two individual apps won't work, as they're not present on both servers. Oh. I did not read the OP's requirements carefully enough.

Re: IE caching problem-
chris derham wrote: never had this problem when i deployed to SolarisI'll try again tommorrow when i have a REAL Operating System to deploy my webapp So you have a web app, serving up web pages, that are being cached in a browser. The browser is not refreshing, for reasons unknown. You say that the clock was incorrect, but now I assume the problem is still occurring. Yet you think that moving the webapp to a real os will help? Browsers cache pages only if they are told to. That's not entirely accurate. It's more like browsers (and proxies) are allowed to cache response content for re-use, except when they are told otherwise. Roughly. The final truth is here : http://www.w3.org/Protocols/rfc2616/rfc2616-sec13.html#sec13 Have you used some kind of technique to check the headers? Fiddler or live http headers? Why are the pages being cached? That is the real question indeed. And indeed it may have something to do with the HTTP response headers (Expires, ETag, etc..) and/or with non-compliant browsers and proxies, and/or browser settings. So having a look at the HTTP headers would be a logical first step. Once you know that, perhaps you can resolve the issue. If I had a car that wouldn't start, I know nothing about cars but I'm reasonably confident that changing the garage won't help the issue that much :-) This thread started reasonably enough, which will certainly have surprised some, considering the OP's historical record on this list. But I am afraid that it has now veered into matters of little relevance to Tomcat per se. In any case, I am fairly sure that Tomcat does not single out IE 9 among browsers, to sneakily introduce HTTP headers that would cause it to misbehave. Given IE's own historical record, I would rather think that the suspicion should be the other way around. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Cluster and SSO
Hello to all, i'm using apache tomcat 7.0.25 with cluster configuration, apache server 2.2 for load balancing and SSO (tomcat) for authentication.

1. You must have the same setting for all all filters in your request
processing chain.
Your stacktrace from IllegalStateException should have mentioned them.
All the valves in the chain should also support async processing (that
is declared programmatically, via Valve.isAsyncSupported() ).
2. Your web.xml (and conf/web.xml) should mark themselves as adhering
to the Sevlet 3.0 specification (with version and probably with
xsi:schemaLocation attributes on the root element).
server.xml snippet :
Connector connectionTimeout=2 port=8084
protocol=org.apache.coyote.http11.Http11NioProtocol redirectPort=8443/
Even the sample program AsyncRequest that comes with tomcat does not
work. :-( it also throws the same exception.
You mean those listed at the bottom of the following page:
http://localhost:8080/examples/jsp/
I've just tested and those examples work with Nio connector in 7.0.27.
I am on WinXP.

Manager activeSessions and customized error page
Hi! I configured the Manager's maxActiveSessions attribute in context.xml. If the configured value is exceeded an IllegalStateException createSession: Too many active sessions is thrown in ManagerBase class. In our application we catch this exception around httpServletRequest.getSession(true) and redirect to an customized error page. Works! Now I activated form based authentication via securiy constraint in web.xml. If I try to open the web application with my browser by sending the first request, the response is empty (status 200 OK). Is there any way to map a static customized error page in this scenario? If not: Is there any other approach to limit the number of sessions? Thanks!

How to start a continuous java application in tomcat
Hi, The scenario is: I have a java application which collects some data from sensors and stores in the database. This java application has to run continuously. On the other hand I have a web application which I am running on tomcat which collects the data from database and display it on the web. Database is same for both applications. I don't mind whether the application runs inside tomcat or outside tomcat. I've tried to make a jar file of the java application and created a simple web application which uses some classes of the jar file. But it is not working. Can anyone please tell me how do I do this. I am sure there should be an easy way to do that. Thank you. Regards.

AW: Manager activeSessions and customized error page

I configured the Manager's maxActiveSessions attribute in context.xml. If the configured value is exceeded an IllegalStateException createSession: Too many active sessions is thrown in ManagerBase class. In our application we catch this exception around httpServletRequest.getSession(true) and redirect to an customized error page. Works! Now I activated form based authentication via securiy constraint in web.xml. If I try to open the web application with my browser by sending the first request, the response is empty (status 200 OK). Is there any way to map a static customized error page in this scenario? It depends on where ErrorReportValve is in the request processing chain in your situation. There were several changes to that (read: fixes) in different Tomcat 7.0.x versions. You did not wrote which version you do use. Sorry! I tested with 7.0.8. If it is reproducible in latest 7.0.27, feel free to create a bug report and attach a simple sample web application + steps to reproduce. It might be that it is already reproducible with the standard example app [1], but I have not tried. [1] http://localhost:8080/examples/jsp/security/protected/index.jsp Now I tried with the standard example and 7.0.27. I get the default 500 error page. Would be great to have a possibiltiy to make a distinguish between this error and any other error. If not: Is there any other approach to limit the number of sessions? I think it is possible with a Filter, Valve or with a SessionListener. It should be also be possible with a custom o.a.c.Manager. YMMV. A Filter was my first approach. But the filter is invoked after authentication has taken place. And for authentication a session is needed. ;-) A HttpSessionListener is invoked AFTER a session is created. It seems that every approach has some ugly pitfalls. :( Best regards, Konstantin Kolinko - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org Thomas - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

XP (Win7 falls in the same category) has good network stack but focused on client applications. There is a good reason why MS charges extra $$ for server versions since they make sure your server application don't perform well on workstation software. The problem is, we've seen the behaviour reported sporadically from customers on windows 2003 server. The only case I've been able to find to reproduce it was this XP system. I'm not sure what to make of the customer reports of the slow downs but at this point, I'm going to have to ask them to use something like ab.exe to do the downloads instead of Internet Explorer (most of them use IE to do it). Maybe there's some stupidity with IE. IE tries to open several concurrent connection at once (RFC says that number is max 3) I'm sure you can simulate that with 'ab -c 10 -k -n 1 ...' I'm not sure how this would be relevant though as the behavior is reproducible with a single connection to download a large file (no concurrenct connections to this site or any other site. There is nothing wrong with tomcat, mod_jk or httpd. It's just your use case. I'm not convinced that there isn't something odd going on but for now I'll ignore it. I may have a stupid use case, but we have had reports out in the field of what appear to be perfectly sane use cases that don't perform. i just can't reproduce them. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

The best you can do is mitigate the attack -- you can't actually prevent it because it's hard to tell the difference between an attacking client and a legitimate client with a really slow connection. You ought to be able to mitigate a lot of these types of attacks using QoS and per-client-IP-limits which are typically configured entirely independently of a web server (although httpd specifically -- and I'm sure others, too -- has modules that can help you do these kinds of things).

If yes, then you should : - let us know which version of Tomcat you are using, under which Java JVM version, on which OS platform - find out what is the catalina base of your Tomcat (you can see all that by executing the version.sh or version.bat script that is in tomcat_install_directory/bin/). Copy and paste the output here. - let us know where, relative to that catalina_base, your webapp is installed - let us know where, relative to that cataline_base, you have installed that jar-file - show us what appears in the Tomcat logs, which shows that your webapp is not working (*) (copy the relevant log lines here). (You should provide this information anyway, even if my effort above is not a good description of your problem. And also correct my summary then.) Note # 1 : copy-and-paste the requested information inside your response. Do not send it as attachments, because this list strips most attachments. Note # 2 : for even more sympathy from the list than what you got so far, do not top-post. Write your answers *below* the relevant questions, not all on top of your message. (Just so that questions and answers can be read logically and naturally, without having to scroll up and down to understand what is relevant to what.)

Links not resolving to their correct path in TC 7.0.27
Hi, I have installed tomcat 7.0.27 on Windows Home premium 32 bit system with JDK 1.6.32. The tomcat is running successfully as service.I can access the home page of tomcat along with manager application. I deployed my application war file via manager application.The war file was pulled from netbeans dist folder. Now when I access my this application via IE,I do below steps, 1. I open this http://localhost:8082/xxx/index.jsp in IE. it works fine, In index page I have several links, for example testservice.jsp 2. so when I click on testservice link, it looks like http://localhost:8082/xxx/testservice.jsp in address bar and page opens fine in IE.No issues in IE. Now the real problem comes when I try to repeat the steps in Firefox and chrome, Step 1 works fine,no issues everything works as expected and index page comes up,but when it comes to step 2, the address changes to http://localhost:8080/xxx/testservice.jsp . now I am not sure as why FF /Chrome are not sticking to the same ports as IE. I have 8080 tied up with netbean and it has Tomcat 7.0.11 but its not running as service. Also I have static custom error page 404 which resolves correctly in 7.0.27 in all three browsers. Can some one tell me what that I am missing now ? PS: This is how I have links in index page, lia href='testservice.jsp'testservice/a/li and all jsp resides in web pages folder.I know this gives direct access to JSP and is bad practice,but thats the seperate task to do in my list. - Kiran - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I'll try this tomorrow. I just want to forward based on the port that the Tomcat instance is running on. The 2 tomcat instances running on the same server is really the same application--but different versions. And, I thought that I could use the existing Apache instance to forward requests to the new version of the app running on tomcat as well. But, if I want (e.g. the tsademo app) the tomcat instance running on port 8009; and tsademo is being forwarded to both ports--how can I be sure that I would get the tsademo running on port 8009 and not the one running on 7009? I tried using the Virtual host in Apache; but, ran into issues with that. Or, should I just go ahead and create an entirely new apache instance for the new tomcat instance? Regards,

Sorry fixed it, it was my fault. Base tag was pointing to 8080.Make sense now.
