Re: Multiple context paths for single deployment
Hi, thanks for replying. What I want is an alias for the context so that more than one url can be used for the same application and that the url used is reflected in HttpServletRequest.getContextPath(). Currently I get two deployments, then getContextPath() returns those two values as expected. I want to get rid of the double deployment but still get the proper context path. -Jan Pid * wrote: On 12/05/2011 11:28, JanAa wrote: Hi, I want to have more than one context path for a single deployment in Tomcat 5.5.28.

Deploying with JMX (but not with manager app) when autodeploy is disabled
Hello,
I have this bit of information from the server.xml
Host

appBase=${host.appbase}
unpackWARs=false
autoDeploy=false

xmlNamespaceAware=false
I haven't manager, host-manager, psi-probe or similar webapps. Is it
possible, using ONLY JVisualVM/JConsole, deploying and start an
application i already copied in the webapps dir?
Thanks

Re: Possible Servlet 3.0 AsyncContext bug in Tomcat 7.0.x
Mark, I wanted to let you know that 7.0.14 (I dl'd the official release this morning) changed the behavior slightly, but it didn't fix the bug. The behavior I'm seeing now is: response.sendError - seems to close the connection immediately (doesn't wait to time out like 7.0.12 did), but you get no headers or content of any kind. response.sendRedirect - no change, still just times out, and you get no headers or content of any kind. Should I open a ticket for this? It's not a showstopper for me, since I can work around it with .setStatus and .setHeader, but I do think it's a legit bug...unless you think I've missed something about AsyncContext usage and I'm doing something wrong.

Re: Multiple context paths for single deployment
Hmm In Tomcat versions up through 6.0, I have cases where I have 1 expanded WAR directory (outside Tomcat's webapps, etc) and then numerous disparate Context XML files under Tomcat/conf, each with their own overrides to the original web.xml (e.g. each getting their own data sources, JNDI env values, context name, etc). It was my understanding that the web.xml override capability of Context was broken in Tomcat 7 (and/or the most recent Tomcat 6??) -- at least for a while, hopefully this has been fixed. Otherwise, however, this seems to work nicely -- 1 deployment, 'n' URLs with 'n' disparate context paths. It does, of course, load 'n' copies of all the JSPs, etc, etc -- so there's definitely some downside in terms of overhead. It is a quick and dirty way to deploy numerous instances of a web app which has unfortunate singletons, e.g. data sources, where you belatedly discover you want a cardinality of 'n' rather than 1. -- Jess Holle On 5/13/2011 8:56 AM, Caldarale, Charles R wrote: From: JanAa [mailto:jan.aage...@norse-solutions.com] Subject: Re: Multiple context paths for single deployment What I want is an alias for the context so that more than one url can be used for the same application and that the url used is reflected in HttpServletRequest.getContextPath().

RE: Multiple context paths for single deployment
From: Jess Holle [mailto:je...@ptc.com] Subject: Re: Multiple context paths for single deployment In Tomcat versions up through 6.0, I have cases where I have 1 expanded WAR directory (outside Tomcat's webapps, etc) and then numerous disparate Context XML files under Tomcat/conf, each with their own overrides to the original web.xml (e.g. each getting their own data sources, JNDI env values, context name, etc). Yes, that still works fine - but it's not what the OP is asking for. He specifically requested *one* application deployment, with multiple URL paths for the *same* application. If what he really wants is multiple deployments using a single copy of the .war file, then keeping the .war outside of the Host appBase and pointing multiple Context elements at it from conf/Catalina/[host] would do nicely. But these are still multiple deployments, and would not be the same application, even though they originate from the same location. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: Multiple context paths for single deployment
Thanks for replying. I was under the impression that the difference between HttpServletRequest.getContextPath and ServletContext.getContextPath() was exactly that the first returned the context path used in the request while the second returned the context path used when processing (http://download.oracle.com/javaee/5/api/javax/servlet/ServletContext.html#getContextPath()). I realise I have to find another route, I still need multiple urls to one application, and I have to identify these in the code.

Sometimes CNFE's are thrown not because the class isn't found but because something the class needs is not being found. For instance, AprLifecycleListener needs the APR native library to work properly, though it's written such that it will catch any exception thrown when the library fails to load.

Re: High Availability in Tomcat?
Hi Konstantin, I have just read the manual regarding the parallel deployment and tested it. IT IS A WONDERFUL FEATURE! And so easy to do! At last my site won't stop every time I redeploy! Thanks a lot for your advice, I wouldn't have noticed this new feature if you hadn't told me to check it.

Take a look at the Parallel Deployment feature in Tomcat 7 http://tomcat.apache.org/tomcat-7.0-doc/config/context.html Best regards, Konstantin Kolinko - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
