| 01:46.47 | jieryn-w | i find lots of bad search hits for getting HTTPS working with apache httpd+tomcat |
| 01:47.17 | jieryn-w | i have ip vhosts, but the ips are all bound to one single eth using aliases |
| 01:47.43 | jieryn-w | i also have many non-https, non-j2ee, vhosts which i need to keep around |
| 01:48.05 | jieryn-w | anyhow, can someone recommend good tutorial for this kind of thing? |
| 01:53.17 | jasonb | jieryn-w: I wrote up a detailed tutorial on it, with step-by-step instructions, including the commands to run in our book Tomcat: The Definitive Guide (O'Reilly). |
| 01:54.00 | jasonb | Oh, actually, I misread what you wrote above.. you're talking about configuring Apache httpd for HTTPS, not Tomcat. |
| 01:54.49 | jasonb | That's a more complex configuration, and yes, you'll find endless bad pages about it. |

| 01:58.04 | jieryn-w | jasonb: that's the problem.. too many useless posts |
| 01:58.21 | jieryn-w | i'd like to just let apache manage all the SSL stuff for us |
| 01:59.08 | jieryn-w | maybe i should remove apache httpd from the picture entirely though; i just kind of assumed that i'd get address already in use exception if i bind to alias:443 |
| 01:59.20 | jasonb | You can.. and requests can be proxied to Tomcat via either HTTP or AJP (unencrypted in both cases).. And then you'd need to configure Tomcat to write URL responses as if the whole thing is running under HTTPS. |
| 01:59.27 | jieryn-w | i use mod_proxy |
| 02:00.07 | jasonb | I strongly suggest running Tomcat stand-alone. You lose half of your Tomcat's performance by proxying all Tomcat requests through Apache httpd. |
| 02:00.35 | jasonb | Plus, Tomcat stand-alone is far easier to configure than httpd --> Tomcat |
| 02:00.46 | jieryn-w | i agree !!! |
| 02:00.51 | jieryn-w | i love tc :) |
| 02:01.15 | jieryn-w | ok, so do you know specifically if i can bind multiple times to :443, e.g., for each of these aliased ip addrs? |
| 02:01.30 | jasonb | Nope, once per IP address. |
| 02:01.41 | jieryn-w | well, i have about 40 or so ip addrs |
| 02:01.49 | jieryn-w | but they are all going through one eth, aliased 39 times |
| 02:02.02 | jasonb | If you can give Tomcat an IP address where it can have port 443, then you can bind to 443.. |
| 02:02.18 | jieryn-w | i should just test this real quick |
| 02:02.22 | jasonb | It doesn't matter that it's all going through one NIC. That part's fine. |
| 02:02.29 | jieryn-w | see if i can bind to alias1:10000 and alias2:10000 |
| 02:02.59 | jieryn-w | your T:TDG, is it very recent? |
| 02:03.00 | jasonb | In fact, on Linux you can use iptables, and remap port 443 to a different port number of your choice where Tomcat is running HTTPS. |
| 02:03.26 | jasonb | jieryn-w: It is recent enough (2nd Edition), and covers Tomcat 6 in a very up to date way. |
| 02:03.27 | jieryn-w | i'm checking if my corporate books 24x7 has it |

| 02:05.56 | jasonb | Yup.. then it's just right. |
| 02:06.10 | jasonb | You should really upgrade to 6.0.29 though.. and that should work just fine. |
| 02:06.20 | jieryn-w | i don't get to control the server |
| 02:06.29 | jieryn-w | but yep, i think .30 was released, or is nearing release, soonish |

| 02:28.31 | jieryn-w | awesome |
| 02:28.44 | jieryn-w | i just did a simple test of binding, and i CAN bind multiple times to the same port with different ip addr |
| 02:28.52 | jieryn-w | even though those ip addrs are all through the same eth |
| 02:28.53 | jieryn-w | w00t |

| 02:48.59 | Zer0_Cool | hi |
| 02:49.02 | Zer0_Cool | wahts up |
| 02:51.23 | jasonb | jieryn-w: Are you using a memory cache or a disk cache? |
| 02:55.01 | jieryn-w | disk |
| 02:55.14 | jieryn-w | with a lot of ram available for ext3 |
| 02:55.22 | jieryn-w | so hopefully it "degrades" into a mem cache |
| 02:56.00 | jieryn-w | anyway, the decrease in complexity for httpd && tomcat --> tomcat may be worth losing a bit of performance gain for mod_cache |
| 02:56.34 | jieryn-w | for each of my vhosts/ipaddrs i have a separate user, and now tomcat is failing to bind to :80 :443 ! shit |
| 03:02.57 | jasonb | It would have to run as root to bind to privileged port numbers. |
| 03:03.21 | jasonb | That's why people tend to bind it to 8443, and then use something to remap 443 to 8443. |
| 03:03.33 | jasonb | (for instance, iptables or authbind) |
| 03:03.49 | jasonb | I've used iptables most of the time, and I do suggest it. |
| 03:04.11 | jieryn-w | 8000/8443 ? |
| 03:04.16 | jieryn-w | or rather, 8080/8443 |
| 03:04.28 | jasonb | You will likely also find that Tomcat does not underperform versus Apache httpd.. |
| 03:04.45 | jasonb | Yeah, 8080 and 8443. |

| 03:07.45 | jieryn-w | yes |
| 03:08.09 | jieryn-w | well, i should be more specific, jetty can be launched as root and then configured to change user itself down to some other id |
| 03:08.11 | jasonb | Hmm, I wonder if it runs the whole JVM process as root in that case? |
| 03:08.20 | jieryn-w | mm..interesting |
| 03:09.03 | jasonb | Nah, with Tomcat, there are just known ways of remapping ports.. it's not built into Tomcat itself. Tomcat is pure Java, all except for the APR connector code, and you'd normally not use that. |
| 03:09.47 | jasonb | Okay, I'm heading out for a bit.. I'll be back later.. cheers.. |

| 20:29.09 | randrewj | campee: mod_proxy_ajp is easy to configure. |
| 20:31.56 | randrewj | heiko: it is typical to have settings in WEB-INF. Esp since the servlet spec requires some configuration in WEB-INF/web.xml. what you are trying to do is probably very application specific. |
| 20:37.13 | *** join/#tomcat prgrmr_ (~prgrmr@unaffiliated/prgrmr) |
| 20:39.02 | heiko | randrewj: yes, i want to set application specific config. is it possible/sensible to have that outside the war file, though? i'd like my production config to just sit on the server |
| 20:41.19 | jasonb | heiko: If your webapp either already implements features that make it possible, or if you're writing the webapp and can make it work, it's most convenient to have per-webapp-instance configuration outside of the webapp for obvious reasons. |
| 20:42.00 | heiko | jasonb: i'm writing the webapp, and wonder how to go about configuring it properly |
| 20:42.22 | heiko | but i don't know which concepts are appropriate for what i want. |
| 20:43.58 | heiko | could i put config options in some xml file in $CATALINA_HOME and retrieve the config options from within my app? |
| 20:54.41 | randrewj | heiko: the spring framework has features to read in xml files to configure an ApplicationContext from files on the classpath or from arbitrary files. |
| 20:55.26 | heiko | ouch, i was hoping to use something smaller than spring :) i'd really just like to get 2-3 key/value pairs from somewhere outside my war |
| 21:00.38 | jasonb | Yes, do something smaller than spring. :/ |
| 21:01.54 | jasonb | heiko: A decent pattern I've seen in practice is: have your webapp look for a system property like -Dmywebapp.config=/myconfigs/configfile.properties and read that at webapp startup, and use those values. |
| 21:02.04 | jasonb | That way, you can set as many of those in the Tomcat JVM as you want. |
| 21:02.09 | *** join/#tomcat calavera (~calavera_@83.37.247.124) |
| 21:08.29 | heiko | ok, so i'd pass a resourcename as an environment property, then use the classloader to get that resource, and get configuration from in there? |
| 21:28.35 | jasonb | heiko: Not really. What I'd suggest is, look for the system property, and if it is defined, read the file directly like: File configFile = new File(propertyValue); .. and then open and read it.. |
| 21:28.52 | jasonb | It's really simple, and works just fine. |
| 21:29.04 | heiko | i see |
| 21:29.20 | heiko | i'll try that, thanks :) |
| 21:30.01 | heiko | a system property would be an "export FOO=file" on a unixy system, right? |
| 21:30.09 | jasonb | Also, if you set that in JAVA_OPTS like: JAVA_OPTS="-Dmywebapp.config=/myconfigs/configfile.properties" (plus other startup opts) then you can change files by just changing this environment variable in Tomcat's environment. |
| 21:30.31 | jasonb | Like: export JAVA_OPTS="-Dmywebapp.config=/myconfigs/configfile.properties" |
| 21:30.52 | heiko | oh, it's a JAVA_OPT thing |
| 21:31.07 | heiko | thanks, trying :) |
| 21:31.26 | jasonb | Well, JAVA_OPTS is used by catalina.sh to start the Tomcat JVM with special startup arguments. |
| 21:39.37 | heiko | err. would i get at the system properties via "(Context) new InitialContext().lookup("java:comp/env")"? |

| 22:13.56 | heiko | got it, my service is configured. thanks, jasonb! |
| 22:20.02 | jasonb | heiko: You're welcome. |
| 22:20.09 | jasonb | heiko: Pretty simple, eh? |
| 22:20.37 | heiko | jasonb: it is :) feels a little brutal, somehow, but i appreciate that it gets the job done. |
| 22:22.31 | jasonb | heiko: After you do it that way for a bit, you'll realize how natural it is to Java.. Java always has system properties.. and it's actually okay for a webapp to read an absolute filesystem path. And, you've separated the configuration out of the webapp cleanly. |
| 22:23.21 | heiko | the clean separation of config and webapp is good, yes. but it seems to me that the application server could provide configuration in a less low-level way |
| 22:23.23 | jasonb | And, to top it all off, the implementation is simple, readable, tiny, and fast. |

| 22:24.05 | heiko | at first i was looking at server.xml and context.xml, but couldn't figure out what went where |
| 22:25.20 | jasonb | There are supported features of servlet containers where it can provide configuration at the container level (outside the webapp), but once you research each one of those (there are several ways of doing it) you'll find that each one of them is overly difficult or abstract.. either difficult to understand the configuration, or difficult for people to *find* the configuration, or difficult for a webapp to hook up to it, etc. |
| 22:26.10 | heiko | that's the sense i got while googling. i was baffled and confused, and wondering if i was even looking at something relevant to my needs. |
| 22:26.40 | heiko | but then, that keeps happening to me with java ee technologies :) |
| 22:27.55 | jasonb | I can tell you from experience, this particular use case is very much like that. |
| 22:28.36 | heiko | cool, i'm glad i've got this sorted out. this was rather frustrating at first. |
| 22:28.47 | jasonb | Also, the system property way is 100% servlet container implementation independent.. you can be sure that it is, because it is so simple. |
| 22:28.55 | heiko | oh yes ... |
| 22:29.12 | jasonb | Also, it does not violate anything in the Java Servlet Specification. |
| 22:29.24 | heiko | i've been shocked how much container dependent stuff is going on with webservices |
| 22:29.56 | heiko | i tried getting my service to run in glassfish once, and noticed that i had no idea how to migrate the user configuration for authentication %) |
| 22:30.09 | jasonb | Well, that happens.. there's competition and money / contracts to win in the SOA space. |
| 22:30.26 | heiko | right |
| 22:31.01 | heiko | well, i do enjoy the service approach to architecture, so far - writing a bunch of REST services and clients, and it's fun so far |
| 22:31.14 | heiko | time will tell if it was a good idea :) but it does feel neat, so far |
| 22:31.51 | heiko | i worry that i might overlook some requirements or lack experience to make good design decisions, of course |
| 22:32.09 | heiko | still, fun stuff :) |

| 23:07.16 | jasonb | heiko: You're not finding that being servlet container impl dependent, are you? |
| 23:54.32 | heiko | jasonb: i didn't notice anything container-dependent about jersey, no. just the way you configure users in a given container, that was a bit of a surprise to me. |
