Re: x-forwarded-for
Boulay Arnaud wrote: I would like to know how I can catch the real client IP address with Tomcat even if there is some proxy between them. If you're using unsecured HTTP, the X-Forwarded-For header might help you in some cases, but as there is no guarantee that all proxy servers add this header it is not practical to rely on it, and in many cases the X-Forwarded-For could be just plain wrong. If you're using secured HTTPS, then the originating IP will be intact (no proxies or caches to worry about), but if the client was behind a NAT router, you will only see the IP address of the NAT router, not the client. I think that http header x-formwarded-for could embed it but I don't know how !!! You (as in tomcat) don't embed the header, the proxy server does - you just need to read the header if it exists.

There can be many virtual hosts per listening port, but only one certificate, and the certificate can only have one name (at the moment) - thus your problem. :( Regards, Graham -- smime.p7s Description: S/MIME Cryptographic Signature

Tomcat 5, proxy and SSL accelerators
Hi all, I have a tomcat server running behind an SSL accelerator. I have used the proxyName and proxyPort config settings to make sure the real name of the server is used by the web application, but I can find no way of telling the web app that it is running on a secure server. Our server sends its URL to another server as part of an information exchange, and as this exchange is XML based and not done using a browser using relative links or the base tag is not possible. Our current hack is to reconstruct the URL, replacing http with https, but it's really ugly. Is there an elegant solution to this problem out there?

Tomcat RPMs and database pools - no joy
Hi all, I have a war that connects to a database pool defined in a Resource section within server.xml. This war is run in a tomcat v5.0.19 environment as binary released by the jakarta project, and works 100%. I now want to deploy the war inside a jpackage RPM version of tomcat on my production server, and use the identical configurations for the Resource section and war, but an attempt to start the application fails like so: javax.servlet.ServletException: Error initialising za.co.fma.patricia.struts.PatriciaPlugin with configuration file at '/usr/share/tomcat5/webapps/patricia/WEB-INF/torque.properties': za.co.fma.patricia.PatriciaException: org.apache.torque.TorqueException: org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null', cause: No suitable driver I tried the v5.0.24 RPM, and the same results were evident. Googling for the above shows lots of questions, but no definitive answers. Usually the problem goes away when the person with the problem goes over the config. In my case I know my config works, because my test environment is 100% functional. I am trying to work out what could be different between my test environment and the final tomcat RPM file. I have checked that the Postgresql driver is placed in common/lib in both the test environment and the RPM environment. In order for tomcat to install at all, I have forced it to ignore the following three dependancies, as (to my knowledge) they are are included in Sun's JDK v1.4.2 (and jpackage provides no compatibility packages to fake these dependancies for JDK v1.4.x): - [javamail].jar (is there already courtesy of Redhat supplied package, but jpackage cannot find it) - [jdbc-stdext].jar (part of v1.4.2, not present in Jakarta's official tomcat release) - [jndi].jar (part of v1.4.2, not present in Jakarta's official tomcat release) Has anybody got database pools and the tomcat5 RPM to work properly together, and was there anything you needed to do over and above the normal Resource configuration?

CONNECT only makes sense with a forward proxy, ie set up use proxy for https in your browser settings. If it works fine direct, but not through the proxy, then the proxy you are using has a problem. If you are trying to use it as a reverse proxy it won't work. The reverse proxy needs to be set up as a receiver of SSL connections, which are then forwarded independantly to Tomcat.

As I understand it, the combination of SSL support and mod_proxy in Apache v2.0 is capable of connecting to a backend server using an SSL connection. So, configure Apache v2.0 with SSL, and use mod_proxy to connect to a Tomcat instance running the HTTP/1.1 connector with SSL support. This way you get encrypted connections between Apache and Tomcat. Or - just let Tomcat handle the request directly using HTTP/1.1 connector + SSL.

mod_jk / tomcat webserver 404 weirdness
Hi, I am having some grief with a new tomcat/mod_jk installation. I've installed the required context in server.xml, and have used the auto-generated apache mod_jk config file to taylor httpd.html. The configured URL works great from the tomcat webserver running on port 8080 by default, but accessing the URL through Apache and mod_jk results in an error 404 in the Apache logfile. A packet sniff on port 8009 indicates no traffic at all - which suggests to me that the Apache side is broken, but I don't understand this stuff clearly enough yet to see through the fog, and the FAQ hasn't yielded any clues.

None of your current defs: JkMount /thh/servlet/* ajp13 JkMount /thh/*.jsp ajp13 will cause the browser URI to be redirected to Tomcat. Try with the following: JkMount /thh/* ajp13 It works now - great! I didn't fully understand the implications of what my java programmer was doing (they make the stuff, I make it live) - I didn't realise the significance of the jsp extension and that in our case it wasn't being used.
