| 15:14.37 | Yiv | As it documented for Tomcat 6, I run the source with `ant download' for necessary libraries, i.e. Eclipse JDT, etc., then `ant' to compile the trunk. |

| 15:19.00 | Yiv | But for some reason it cannot find the Main class. Tomcat compiles the built files to tomcat6/output/built directory but even running it from that location in Eclipse spits an error message that it's unable to find the Main class (aka Bootstrap) even though all the .jar files are there (even tomcat6/output/classes shows everything has been compiled. |

If you make eclipse run it exactly like that, and use the CWD of Tomcat's CATALINA_HOME dir, then Tomcat should be happy. So, how to do that is more of an eclipse question than it is a Tomcat question. |

| 17:46.59 | Yiv | jasonb, I took your advise and examined the command line options that the startup.sh initialized Tomcat with and accordingly augmented some of the options to the Argument tab in Run Configuration. Apparently, none of those CATALINA HOME/BASE/TEMPDIR was being set. |
| 17:47.40 | Yiv | Of course, I had to still add Bootstrap.jar to the classpath but it can be done either way (argument or not). |
| 17:48.00 | jasonb | yeah.. You'll figure it out. :) |
| 17:49.00 | Yiv | It seems like, now that I've included that downloaded libraries via `ant download' in the classpath (TOMCAT_LIBS_BASE), it is loading Eclipse JDT as well that I don't see when I start Tomcat from command line. |
| 17:49.28 | Yiv | Those auto-recompilers for JSP, right? |
| 17:54.49 | jasonb | Well, Eclipse JDT is for JSP, yes. But, since you already built it into Tomcat, Tomcat is just supposed to handle it from there. |
| 17:58.46 | Yiv | I don't know about "built in," but I suppose if I place it in a classpath, Tomcat replaces it with its default. Or is Eclipse JDT "is" the default JSP compiler? |
| 17:59.38 | Yiv | Damn grammar. |
| 18:00.05 | Yiv | Not a good day to ask questions when your brain is tab dancing on itself. |

So obviously when I start Tomcat with the startup.sh script, it does't have Eclipse JDT in its path. Does it mean that the Tomcat instance that runs from the compiled version with startup.sh cannot compile any JSP? |

| 21:25.00 | Primer | I don't need a typed language for doing web crap |
| 21:25.12 | Primer | one where I have to jump through a myriad of hoops to get simple shit done |
| 21:25.58 | Bananobot | I find it funny how long-time Java developers ask, "If you don't have type safety, how can you know that anything is going to work?" while in my experience, PHP apps have been much more stable and bug-free than Java apps I've used. |
| 21:26.00 | Primer | a simple example: Creating a data structure to ultimately encode into JSON or XML |
| 21:26.11 | Primer | Bananobot: same here |
| 21:26.14 | Yiv | Enough with this junior high PHP chit-chat. Let's talk about sex baby, let's talk about Java. ;p |
| 21:26.28 | Bananobot | sex baby? That's illegal! |
| 21:26.56 | Yiv | Ok, I wish I had stumbled upon this page earlier; it would have saved some time letting me to set the VM argument in Eclipse before going around the block a few time. |

| 21:26.58 | Primer | Thing is, your code is only as good as the people that wrote it |
| 21:27.19 | Primer | in the case of the stuff I have here, I see NPE's ALL THE TIME |
| 21:27.35 | Primer | all because they didn't check to see if the object they got back wasn't null |
| 21:27.43 | Primer | that's commonplace for java |
| 21:27.50 | Bananobot | Building Tomcat, step 1: sudo apt-get install tomcat6. step 2: Press Enter. |
| 21:28.55 | Primer | no install candidate |
| 21:29.00 | Bananobot | :o |
| 21:29.02 | Primer | Debian lenny |
| 21:29.02 | Bananobot | What distro? |
| 21:29.12 | Bananobot | It's probably named differently. I'm on Ubuntu. |
| 21:29.18 | Primer | no |
| 21:29.22 | Primer | it's not |
| 21:29.26 | Primer | there is no 6 for Lenny |
| 21:29.30 | Bananobot | Ah |
| 21:29.33 | Primer | only 5 |
| 21:31.23 | *** join/#tomcat t0ka (~Administr@cpc2-ware5-2-0-cust677.9-1.cable.virginmedia.com) |
| 21:31.58 | Primer | Anyhow, I was happy to have found third party software that implemented non-local session storage in tomcat |
| 21:32.29 | Primer | this will allow me to do non-sticky load balancing...something the tomcat spec doesn't allow for |
| 21:32.39 | Primer | that's what I mean when I say "dated specs" |
| 21:33.24 | Primer | in PHP, doing that involves changing a php.ini directive and setting the IP of the memcache server |
| 21:34.26 | Primer | then voilà , I have a cluster of machines all sharing the same session store |
| 21:34.57 | Primer | without need for a multi-cast network (something that Amazon's EC2 doesn't support, btw) |
| 21:36.41 | Primer | I spent close to a week trying to get tomcat to share a common session store, only to find that tomcat session is held in its own memory. The only alternative involves session replication, which only supports sticky sessions |
| 21:36.47 | Primer | anyhow, </rant> |

| 22:22.04 | Primer | jasonb: the only one that exists. The one I pointed out to you about a week or so ago: vcloud-session-manager |
| 22:22.42 | Primer | that one is a complete implementation of the session manager, where sessions do not exist in tomcat memory, but a rabbitmq server across the wire |
| 22:28.35 | Primer | but IN a rabbitmq server, that is |
| 22:28.43 | Primer | at least that's my understanding |
| 22:28.56 | Primer | this will finally allow me to have non sticky sessions in tomcat |
| 22:34.08 | *** join/#tomcat sysiphus (~sysiphus@117.196.132.47) |
| 22:48.26 | Primer | except it's not quite working |
| 22:48.26 | jasonb | Primer: Oh. Okay. Interesting. |
| 22:48.38 | Primer | I keep getting a different session ID on every hit |
| 22:49.09 | jasonb | It's such an odd case that I'd be surprised if any OSS worked alright for that, other than Ehcache. |
| 22:49.26 | Primer | Why do you think this is odd? |
| 22:49.32 | Primer | Just because it doesn't fall within the spec? |
| 22:49.50 | Primer | http://github.com/jbrisbin/vcloud/tree/master/session-manager/ |
| 22:49.55 | Primer | in case you want to look more into it |
| 22:50.04 | jasonb | It's clustering (like less than 1% of Tomcat users right there), and it's not sticky (bringing you down to about 0% of Tomcat users). |
| 22:50.30 | Primer | The guy who wrote it makes a valid argument for it, IMO |
| 22:50.45 | Primer | Let me find the article |
| 22:51.02 | Primer | http://jbrisbin.wordpress.com/2010/04/09/non-multicast-tomcat-session-clustering-with-rabbitmq/ |
| 22:52.34 | jasonb | Yeah, I've seen this stuff. I didn't realize it was non-sticky. |
| 22:53.27 | jasonb | (I hadn't read the wordpress article yet) |
| 22:54.29 | jasonb | At least you clearly know who to ask about it not working properly. :) |
| 22:55.46 | Primer | indeed |
| 22:56.04 | Primer | One thing I don't get is why must everything involving tomcat be so complicated? |
| 22:56.31 | Primer | I only have knowledge of PHP as a basis of comparison |
| 22:56.47 | Primer | but in the world of PHP, I understand how sessions work |
| 22:58.16 | Primer | By default, sessions are stored in a file on the web server. When a request with a session cookie comes in, that file is read and its contents are de-serialized into the PHP process, usually an apache child process, the request is handled, and if the session changes, it is serialized and written back to the same file |
| 22:58.45 | Primer | In the case of PHP with memcache, the same thing happens, only instead of using files, a connection to memcache is used |
| 22:58.49 | Primer | both are fully atomic |
| 22:59.12 | Primer | I just can't imagine why this would NOT be desirable in tomcat |

| 23:55.32 | jasonb | Primer: Well, if it's not buried in a package, then it isn't tightly integrated, and can't work properly, as it turns out. |

| 23:57.05 | jasonb | Primer: Also, which init script you should use depends on which Linux distro you're running it on.. That is, all except for the newest one I wrote as part of Tcat Server, which works with all Tomcats 5.5 through 7, and also on all Linux distros. |
