Re: [jetty-users] Jetty Block IP based on visits
Hi Cheney, jetty doesn't support this out of the box, no. But you can deal with it yourself by for example writing a custom handler (http://wiki.eclipse.org/Jetty/Howto/Write_Jetty_Handler) which counts the requests per IP per hour/day and respond with an error page if the configured limit has been reached. If you're expecting a huge amount of requests be careful on how you track requests as this might need a big amout of memory depending on how you count/store the requests from the last day for example.

[jetty-users] Default error handling in jetty
Hi there,
Whenever webapps deployed to jetty fail, one gets the message from the
exception set in the status line:
stefan landro@mac-stefanl:~/tmp $ wget -S http://localhost:8080/test
--2011-12-05 09:02:05-- http://localhost:8080/test
Resolving localhost... 127.0.0.1, ::1, fe80::1
Connecting to localhost|127.0.0.1|:8080... connected.
HTTP request sent, awaiting response...
HTTP/1.1 500 My detailed exception Message
This is quite unfortunate, since such an exception message might leak lots
of information about the application to a bad guy.
In addition, if for some reason the custom error handling in your web app
(error-page etc in web.xml) fails, jetty returns a default error page
(see code below), leaking even more details about the exception (the entire
stack) in addition to the Powered by Jetty line, providing the bad guy
with even more details.
Wouldn't it make sense to remove this functionality from jetty?
Cheers,
Stefan

Re: [jetty-users] Jetty Block IP based on visits
If you prefer servlet filters to jetty handlers, you could of course use that instead. Btw, users coming from behind an http proxy often use the same ip address. In addition, these same proxies often use several ip addresses.

Re: [jetty-users] Jetty Block IP based on visits
Hi Jan, Thanks for sharing this - didn't know Jetty can do so many things. I have a bit read and this is more suitable when servers can't handle big amount of requests and want to pick some for priority processing. In our case, is some IP consumed huge bandwidth from our server/datacenter, 5G per day from one IP, and everyday. We want to keep it down to lower our data centre costs.

[jetty-users] Using OpenJPA in embedded Jetty, cannot find persistence.xml
Hi, I am using embedded jetty and the directory structure of the executable jar file is: /com/myproject/frontend/FrontendMain.java /com/myproject/frontend/servlets/HelloServlet.java /WEB-INF/classes/META-INF/persistence.xml /libs/*.jar The Main-Class is com.myproject.frontend.FrontendMain. I set appropriate class-paths in manifest files, but the openjpa cannot find persistence.xml file. I have tried everything like copying persistence.xml in the following folders: /WEB-INF/persistence.xml /META-INF/persistence.xml /persistence.xml /lib/persistence.xml Please note that its pure embedding, everything is set programmatically, so no war architecture is involved. I have been trying all weekend but with no success. I really want to use embedded jetty in my project, but if JPA doesn't work, I will have to try tomcat unfortunately.

Re: [jetty-users] Logging Custom Handlers JUL
Joakim, i am trying to integrate the custom logger into jetty, but for some reason i can't get it to work. Let me give you where i am thus far. I have followed your instructions here. My custom handler does indeed get all the logging that Jetty itself kicks out. I am able to confirm that my custom handler is running. However, what i cannot get, is for any class deployed in my webapp to reach to the custom logging handler. It just refuses to get there. So my questions are: 1/ Where should one place my custom handler jar file? You noted before that /lib/etc/ is too late, so if that is the case, then where? 2/ Should i run with --exec ? 3/ The classloader that handles the webapp, will that use the custom handler that the core jetty has created? I feel so close to getting this working, yet i am no further forward from the moment i started. I created an example project showing how to set this up, see https://github.com/jetty-project/jetty-and-jul-example. ___ jetty-users mailing list jetty-users@eclipse.org https://dev.eclipse.org/mailman/listinfo/jetty-users
Re: [jetty-users] Using OpenJPA in embedded Jetty, cannot find persistence.xml
Amaltas, Jetty itself doesn't find or read the persistence.xml file, that's something that is done by the jpa. I think maybe the jpa is expecting to find the persistence file inside a jar file, so have you tried putting it inside a jar file in WEB-INF/lib? If that doesn't work, then you might need to track down the doco on the jpa impl and check where it is prepared to look for its initialization file. cheers Jan On 6 December 2011 12:19, Amaltas amal...@amaltas.org wrote: Hi, I am using embedded jetty and the directory structure of the executable jar file is: /com/myproject/frontend/FrontendMain.java /com/myproject/frontend/servlets/HelloServlet.java /WEB-INF/classes/META-INF/persistence.xml /libs/*.jar The Main-Class is com.myproject.frontend.FrontendMain.
