I'm going to go out on a limb and make a recommendation that is counter to the the other responses thus far: upgrade. Why? Two reasons: 1. Tomcat 7 needs more real-world testers 2.

Re: Problems installing Tomcat on Windows 2008
I un-installed the service and rebooted. Then I reinstalled it as an administrator from the command line, and started it via Tomcat6w.exe as an administrator (without any modifications to the Java tab). The service started without issue.

The mapping is done in org.apache.tomcat.util.http.mapper.Mapper Note, that Mapper.find(MapElement[], String) and similar methods perform a binary search, so how your use case can be plugged into it? All requests go through Mapper, so its performance is important.

I, personally, like the general idea of making it more flexible. You may file an enhancement request in the Bugzilla (if there is none yet), though one with a patch has more chances. http://tomcat.apache.org/bugreport.html#Patches_and_enhancement_requests > As a workaround, I can recommend looking at the UrlRewrite filter, http://www.tuckey.org/urlrewrite/ It might be that it will help, but I am no so sure. BTW, you can put those names in an external file and use it in the server.xml as an XML entity. Like the example in http://wiki.apache.org/tomcat/FAQ/Password and use JMX or call mapper.addHostAlias(..) directly to add aliases programmatically at runtime. (though there is no guarantee that the Mapper API does not change between Tomcat minor releases).

Several hosts within one tomcat / catch-all problem
Hi We have a web application which usually runs on a certain host all alone - it is the only context for that host. However, it allows to use different hostnames and therefore we use aliases in our server.xml per host. Now more and more users of those application want to use more subdomains and we have lots of trouble keeping the server.xml updates with all those hostnames. It would be a huge advantage to be able to tell tomcat to use all subdomains of a given domain in one step. Such as *.domain.tdl Or domain.tld So here are my questions: 1) Can this somehow be archived using tomcat 6? (We are currently running 6.0.29.) 2) Can the somehow be archived using tomcat 7? (As I believe (and fear) the answer to the first two questions are "no", two more:) 3) Would it be difficult to add this feature? 4) Where would I start to work on if I tried to create a patch for tomcat myself? 5) Would there be any chances to get that patch later-on included into trunk?

Richard Pless wrote: If I run startup.bat, Tomcat starts successfully. I navigated to http://localhost:8080 and saw the Tomcat page. Ok, that means at least that there is nothing wrong with your basic Tomcat, and that you have at least a working JVM. It does not really tell us if it is running under a 32-bit or 64-bit JVM though. Starting with startup.bat also does not use the tomcat6.exe wrapper, so it still does not tell us why that one fails. As Chuck mentions, the type of error you are seeing is typical of trying to start a 64-bit JVM with a 32-bit tomcat6.exe, or vice-versa. You also mention that the Java tab on tomcat6w.exe says "use default". Would that be the first one found in the PATH ? Do you have more than one JVM on the machine ? If you just enter "java -version" in a command window, and then retry with the full path to the java.exe which you think Tomcat is using, do you get the same answer ? - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

That shouldn't be necessary, as long as the proper DLL is available to the Windows loader (usually from C:\Windows\System32).

Re: Problems installing Tomcat on Windows 2008
If I run startup.bat, Tomcat starts successfully. I navigated to http://localhost:8080 and saw the Tomcat page. Unfortunately I can't get the service to start using "Tomcat6.exe //IS//" from the command line, Tomcat6w or Server Manager -> Services. I'm using all of the defaults in Tomcat6w. On the Java tab, 'Use Default' is checked and everything else is blank. I found the following error in my log: "The Tomcat6 service terminated with service-specific error 0 (0x0)." When I searched for the error in user groups, the only answer that I found was to copy msvrc71.dll to my c:/c/tomcat/bin directory. I've tried that and it doesn't seem to help.

It is a GUI program which allows to edit the Registry settings of the Tomcat Service. Maybe you can spot there what is missing. For info, "tomcat6.exe" is actually the Commons Daemon "procrun" mentioned above in the log. It is just renamed. tomcat6.exe is a "wrapper program", which reads the Registry settings of the Tomcat service and starts the JVM accordingly (or tries to). It looks like it cannot start the java JVM for some reason. Maybe also the Windows Event log will give a clue ? - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Problems installing Tomcat on Windows 2008
Hi All, I'm having problems installing Tomcat 6.0.29 as a service on a Windows 2008 server.

Re: EXTERNAL: Re: Tomcat hung
In your full production trace, is there an indication which thread has the "<0xd50244e8>" lock? I've debugged similar situations where threads were "blocked waiting for monitor <0x.>" (getting java.sql.Connections, as it turned out) -- identifying & examining the thread that had locked that monitor (with a message something like "grabbed monitor <0x>") helped quite a bit w/debugging.

It should have read: Disclaimer: We perform many types of J2EE consulting. Touché. One should not write emails while eating dinner. But I think the message was clearly constructive.

RE: Problems with new mod_jk and possible misinformation on the website
Thank you very much Chris, I've checked the md5sum and file information for the mod_jk that failed and it's the same, so it seems to be a misplaced description, at least at the rediris.es site here in Spain. All my log levels are set to debug, I will compile my own mod_jk. I hope to give it a try this weekend so I will get back to you with the results. I will make sure that it's not a problem with workers.properties or mod_jk.conf, I don't use urimap.properties, I will try that too. Anyway, if my problem persists I will attach all the configuration files Thanks again, have a nice weekend! > Date: Thu, 18 Nov 2010 10:07:57 -0500 > From: ch...@christopherschultz.net > To: users@tomcat.apache.org > Subject: Re: Problems with new mod_jk and possible misinformation on the > website > > -BEGIN PGP SIGNED MESSAGE- > Hash: SHA1 > > > > On 11/18/2010 7:01 AM, Héctor Gómez wrote: > > Hi, I'm running a CentOs 5 with Apache 2.0.52.

Yes, there are, but you should note that most release versions of Tomcat are associated with a version of the Servlet Specification (Servlet 3.0 in 7.0's case). See: http://tomcat.apache.org/whichversion.html Tomcat 7.0 has not yet been declared stable, but is thought to be approaching that point. If you need or want Servlet 3.0 features then yes, upgrade, - if not, is there a compelling reason to upgrade? Perhaps not yet. Upgrading to the 'latest and greatest' may not be necessary for you at this point, but I'd recommend trying it in a dev environment, if you have one, because getting feedback about the server is important. p > Thanks > 0x62590808.asc Description: application/pgp-keys signature.asc Description: OpenPGP digital signature
