| 03:47.07 | Blitz__ | I think logging in locally always works |
| 03:48.44 | atchun | could it possibly that your link to it may be disrupted and not able to connect? perhaps look at the logs for your attempt to logon |
| 03:52.31 | Blitz__ | checked. nothing in the logs |
| 03:52.47 | Blitz__ | a link to the computer itself? so then it wouldn't have anything to do with tomcat? |

| 09:32.06 | Sathamoth | Hello. I have a question about thread safety in my webapp (running under Tomcat 4). I would like to extract some data from every HTTP request (headers) and put that into Session. Can I do the extraction in static method, or do I need to create new "extractor" object with every new request? |
| 09:33.26 | linuxfreck | Sathamoth: thread safety is a problem when you use class or other types of global variables |
| 09:33.41 | Sathamoth | I'm concerned about thread safety because if I have something like host = request.getHeader("host"); auth = request.getHeader("Authorization"); in static method then those lines could be executed by different threads at the same time, right? |
| 09:34.39 | Sathamoth | so basically I'd get "host" from threadA and "auth" from threadB |
| 09:34.41 | linuxfreck | Sathamoth: what type of vars are auth and request? |
| 09:35.06 | Sathamoth | request is HttpServletRequest I get in JSP |
| 09:35.16 | Sathamoth | auth and host are just Strings for the sake of example.. |
| 09:36.40 | Sathamoth | I was thinking about using ThreadLocals, but I don't think that would synchronize any code execution.. |
| 09:36.56 | linuxfreck | Sathamoth: hmm I think there is some confusion here |
| 09:37.17 | linuxfreck | Sathamoth: if the variables are local to the function, no threads will access them concurrently |
| 09:39.02 | linuxfreck | maybe you can give some code? |
| 09:40.39 | Sathamoth | so if I have a public static method which gets data from httpServletRequest passed to every servlet and several threads call that method at the same time I shouldn't get any problems with method variables getting data from different request objects? |
| 09:40.59 | Sathamoth | method variables = local variables even.. |
| 09:41.07 | linuxfreck | yes |
| 09:41.50 | Sathamoth | is there some magic in Tomcat then or is this default behaviour :) ? |
| 09:42.27 | linuxfreck | this is default behaviour |
| 09:42.37 | linuxfreck | you probably want to read some doc on threads |
| 09:42.45 | linuxfreck | e.g. http://java.sun.com/docs/books/tutorial/essential/threads/ |
| 09:45.56 | Sathamoth | yeah I've read that, but there's no info about static methods |
| 09:46.55 | Sathamoth | I've had some problems with getting wrong preferences from my singleton (static) PreferenceLoader because I had two copies of my webapps loaded into Tomcat so I've been a bit paranoid about threads.. |
| 09:47.02 | Sathamoth | (and statics) |
| 09:47.16 | linuxfreck | well it's basically the same |

| 21:31.24 | quas | or know how to disable JULI? |
| 21:35.51 | quas | nevermind |
| 21:39.14 | jasonb | quas: You wrote a custom JULU log handler? :) |

| 21:39.21 | quas | nah |
| 21:39.26 | quas | oldstyle log handler |
| 21:39.31 | quas | but it doesn't seem to work with JULI |
| 21:39.45 | quas | i can't believe they replaced Sun's LogManager implementation in a minor revision change |
| 21:39.48 | jasonb | Well, logging is way different in 5.5, and it did change right up until 5.5.9. |
| 21:40.00 | jasonb | Yeah.. they did. |
| 21:40.05 | quas | dude |

| 21:41.44 | jasonb | Log4j has problems. It's better than what was there before it, but it's got serious things wrong with it. |
| 21:42.13 | jasonb | I don't know JULI really yet, but it sounds okay so far.. |
| 21:42.26 | quas | yeah. i was thinking about my session-domain change -- i guess i could move the config out of web.xml and into tomcat's context config, to make it spec compliant, but it just doesn't seem like the natural place to put it. |
| 21:42.57 | quas | the basic idea is good: to allow different web apps to specify their own logging. |
| 21:43.07 | quas | sounds useful. |
| 21:43.27 | quas | but for now, i'm disabling it. |
| 21:43.33 | Sou|cutter | https://logn.dev.java.net/ <-- Epesh has a logging library |
| 21:43.49 | Sou|cutter | I always thought that was a clever name |
| 21:44.26 | quas | totally. |
| 21:45.20 | jasonb | quas: Well, but what you're trying to do isn't specified in the Servlet spec, which means it becomes a container implementation specific feature, which in this case makes it a Tomcat specific feature, which means it should be configured in a Tomcat config file. |
| 21:45.50 | jasonb | quas: You should probably mail the SERVLET-INTEREST mailing list and make your case for this feature to be part of the Servlet spec, in which case it could be configured in web.xml. |
| 21:46.11 | quas | thanks for the suggestion, i think i will. |
| 21:46.55 | quas | jasonb: are you a tomcat developer? |
| 21:48.06 | jasonb | quas: Define "Tomcat developer".. |
| 21:48.47 | quas | does any code from tomcat's HEAD branch belong to you? |

| 21:52.26 | jasonb | I've been a committer on other projects before Tomcat. I've had my fun. |
| 21:52.45 | jasonb | But, some of Tomcat's source has my name on it. |

| 21:53.48 | jasonb | Well, the book. |
| 21:53.50 | Sou|cutter | which book? |

| 21:54.08 | jasonb | (O'Reilly) |

| 21:54.42 | jasonb | I'm the only author working on the 2nd edition.. which hopefully I can finish around the end of this year. |
| 21:54.55 | quas | helped me a lot with writing a session manager impl. |
| 21:55.06 | Sou|cutter | nice |
| 21:55.17 | jasonb | I've got some nice code to put in it already. Mainly, a brand new Linux RPM package for Tomcat 5.5.. It's some of the best code I've written I think. |
| 21:55.41 | jasonb | quas: I'm glad it helped you. I spent 8 solid months on just my portion of that book. |
| 22:00.17 | *** join/#tomcat loktar (EatMyShort@ems02.your-freedom.de) |
| 22:00.37 | quas | yeah, the tomcat docs from apache are pretty sparse |
| 22:02.06 | jasonb | Some of the other committers also have books, but they're all out of date at this point. |
| 22:02.36 | jasonb | Sou|cutter: Which OS do you run? |
| 22:02.37 | Sou|cutter | I dunno, I think the documentation is ok.. it covers many common things. |
| 22:02.48 | quas | if you deviate slightly |
| 22:02.53 | quas | you're out of luck |
| 22:02.58 | Sou|cutter | jasonb: winblows for work |
| 22:03.33 | jasonb | Sou|cutter: That's just it: it does cover the common things well, except for a few cases where it's just plain factually incorrect. But, all the other cases that are really more like business use cases, those either aren't covered or are so terse and ambiguous that they might as well not be covered at all. So, that's where our book comes in. |
| 22:03.41 | jasonb | quas: Exactly. |
| 22:04.01 | jasonb | Plus, there's lots of "everyone does this, so it MUST be in the docs.." and then when you look, it's not. :) |
| 22:04.27 | jasonb | Sou|cutter: Bummer. |
| 22:04.37 | Sou|cutter | jasonb: Oh, sure. I agree -- but I guess I just don't mind that it's not documented enough that a book would be unnecessary. I mean somebody who is paid to write a book will do a better job than somebody freely writing docs 99% of the time (and I'm fine with that) |
| 22:05.26 | jasonb | Sou|cutter: Yup. Mainly. I do wish our book could also be freely available online. I'd open it up if it was just my choice. |
| 22:05.38 | jasonb | (while still selling the printed form) |
| 22:05.41 | Sou|cutter | free docs to me are kinda like a skeleton outline... books fill in the cracks and interesting real world problems |

| 22:37.33 | quas | like i said, even if you don't want to use Ruby, the Rails idea is pretty awesome. |
| 22:37.45 | quas | you could port the framework to any language |
| 22:40.37 | jasonb | quas: Then I can't wait to try out Java on Rails -- if what you say is true, there will be one. |
| 22:41.05 | Sou|cutter | jasonb: also, though, I don't know that they're directly comparable.. you can use struts with spring (I'm not sure where that fits in since I'm not interested in that) |
| 22:45.42 | jasonb | Sou|cutter: Yeah. These web frameworks don't exactly overlap. |
| 22:46.14 | jasonb | puff must be busy. |
| 22:47.28 | quas | spring is kinda out there |
| 22:47.40 | quas | the whole IOC idea |
| 22:47.57 | quas | i'm not sure if it's not practical, or if i'm just so unused to using it |
| 22:48.27 | Sou|cutter | probably both |
| 22:48.38 | quas | springs a lot like rails -- easy things are easy (easier, not as easy as rails), but the slighties deviation is either a) unsupported or b) not documented |
| 22:50.21 | Sou|cutter | any which way you slice it, I'm happier not rolling my own |
| 22:51.09 | Sou|cutter | Unless I get hit with a great idea like a lightning bolt, I think rolling my own'd just be a waste of my time |
