| 02:01.45 | aharth | hi guys... i try to do 100+ http lookups within a servlet, and i go crazy trying |
| 02:02.19 | aharth | because i shouldn't spawn new threads i thought i use async httpclient, but that doesn't work either |
| 02:02.54 | aharth | 100 lookups that take 200ms as a test case take > 20sec when run from the servlet |
| 02:03.03 | aharth | any pointers would be appreciated |

| 17:41.47 | Einzig_ | Using ubuntu, openjdk, tomcat 6: package javax.servlet does not exist |
| 17:42.06 | Einzig_ | when compiling a servlet |
| 17:45.05 | hvesalai | include servlet-api.jar in classpath |
| 17:50.28 | Einzig_ | in build.xml : <property name="catalina.home" value="/usr/share/tomcat6/bin"/> |
| 17:50.52 | Einzig_ | I read on several forums that the shell variable is not used in this |
| 17:52.00 | hvesalai | ?? |
| 17:53.54 | Einzig_ | Maybe that information was wrong. |
| 17:54.08 | hvesalai | I suggest you don't read forums, they have bad info |
| 17:54.41 | hvesalai | Instead, read the manuals your self. |
| 17:54.53 | Einzig_ | I tried, but they are lacking |
| 17:55.02 | hvesalai | what are they lacking? |
| 17:55.12 | Einzig_ | they are incomplete. |
| 17:55.18 | Einzig_ | well, that is |
| 17:55.32 | Einzig_ | I am following a tutorial from an oreilly book |
| 17:55.48 | Einzig_ | encountering lots of problems |
| 17:55.48 | hvesalai | aha |
| 17:55.53 | hvesalai | which book? |
| 17:56.12 | hvesalai | maybe catalina.home should not point to the bin directory of our tomcat |
| 17:56.14 | Einzig_ | installed the binary, missed directories that are in the source package apparantly |
| 17:56.31 | Einzig_ | missing build.xml altogether |
| 17:56.38 | Einzig_ | It's tiresome. |
| 17:57.01 | hvesalai | which package do you mean? |
| 17:57.10 | Einzig_ | the tar.gz |
| 17:57.13 | Einzig_ | anyway |
| 17:57.14 | hvesalai | of tomcat? |
| 17:57.21 | Einzig_ | yes |
| 17:57.28 | hvesalai | afaik there never was a build.xml in tomcat package |
| 17:57.32 | Einzig_ | so how exactly do I have to set this classpath? |
| 17:57.45 | Einzig_ | You mean defining $CATALINA_HOME? |
| 17:57.49 | hvesalai | the servlet-api.jar is in the tomcat6/lib directory |
| 17:57.59 | Einzig_ | no it is not |
| 17:58.03 | Einzig_ | it is in the bin directory |
| 17:58.23 | hvesalai | which version of tomcat do you have? |
| 17:58.29 | hvesalai | and where did you get it? |
| 18:00.06 | Einzig_ | tomcat 6.0.33 . IT is a binary from the tomcat site |
| 18:00.10 | Einzig_ | erm no |
| 18:00.16 | Einzig_ | from the distro |
| 18:00.36 | Einzig_ | I then downloaded the source for the missing directories |
| 18:00.37 | hvesalai | the distro puts things in weird places |
| 18:01.19 | hvesalai | so if you are new to java development then it's best you don't use the distro tomcat |
| 18:02.20 | hvesalai | download here: http://tomcat.apache.org/download-60.cgi#6.0.33 |
| 18:03.13 | Einzig_ | I told you 3 times that I downloaded it already though |
| 18:04.08 | hvesalai | Einzig_: if you wont help, mind your tone |
| 18:04.26 | hvesalai | so why is your catalina.home is still pointing to the distro? |
| 18:04.37 | hvesalai | where did you unpack the tar.gz that you downloaded? |
| 18:05.10 | Einzig_ | in my home directory, as I just wanted to copy the missing the directories |
| 18:05.18 | hvesalai | don't do that |
| 18:05.26 | Einzig_ | thing is |
| 18:05.35 | hvesalai | unpack and point your build.xml to the place where you extracted the tar.gz |
| 18:05.57 | hvesalai | which build.xml is that? is it from some oreilly example? |
| 18:06.03 | Einzig_ | It should later be used in a production environment, so it might be nice to use the binary for easier upgrade |
| 18:06.16 | Einzig_ | No, I used one in the examples directory or sth |
| 18:06.49 | hvesalai | hmm... there is no build.xml in the official tomcat package |
| 18:07.01 | hvesalai | not at least in the bin version of it |
| 18:07.05 | Einzig_ | not according to my search results |
| 18:07.33 | hvesalai | I don't understand... who said there should be some build.xml? |
| 18:07.57 | Einzig_ | a forum post on how to solve the error I gave . |
| 18:08.08 | Einzig_ | cannot resolve the servlet package or so |
| 18:08.26 | Einzig_ | it has to know where to find the catalina home directory |
| 18:08.39 | Einzig_ | so I entered it in the build.xml document |
| 18:10.58 | hvesalai | each build.xml is different, you have to have a build.xml that is for the code you are compiling |
| 18:11.16 | hvesalai | there are no examples in the tomcat 6 distribution |
| 18:11.45 | hvesalai | but anyhow, if you have some example webapps and the build.xml for them |
| 18:11.50 | hvesalai | then you need to see how it uses the catalina.home |
| 18:12.02 | hvesalai | and where it tries to find the servlet-api.jar |
| 18:12.24 | hvesalai | I suspect that it wants to find the servlet-api.jar under ${catalina.home}/lib/ |
| 18:12.31 | hvesalai | because that's the normal place for it |
| 18:16.25 | Einzig_ | ok |
| 18:18.32 | Einzig_ | apache-tomcat-6.0.33/webapps/docs/appdev/sample/build.xml and the examples are under the webapps directory |
| 18:18.42 | hvesalai | ok |
| 18:19.58 | hvesalai | there is no build.xml for that |
| 18:20.26 | Einzig_ | So where does the build.xml go? |
| 18:20.49 | hvesalai | apache-tomcat-6.0.33/webapps/docs/appdev has a build.xml.txt |
| 18:21.45 | hvesalai | you can copy that |
| 18:21.51 | hvesalai | just remove .txt from it |
| 18:22.13 | Einzig_ | copy to where? |
| 18:22.19 | hvesalai | to the sample directory |
| 18:22.23 | Einzig_ | huh |
| 18:22.24 | hvesalai | if you want to build that |
| 18:22.24 | Einzig_ | why |
| 18:22.30 | hvesalai | what do you want to build? |
| 18:22.54 | hvesalai | if you want to build your own app, then copy it there |
| 18:23.09 | hvesalai | but then you have to see that your own app has the directory structure expected by the build.xml |
| 18:23.46 | Einzig_ | ok, so it should not go under the tomcat6/app/ directory |
| 18:24.06 | hvesalai | the build.xml goes where ever your source code is |
| 18:24.30 | hvesalai | to the root directory of your webapp project that you want to compile |
| 18:24.41 | Einzig_ | ok |
| 18:27.04 | hvesalai | you know that the build.xml is used to control the ant build tool. |
| 18:27.15 | hvesalai | You can also crate webapps with IDEs, such as eclipse |
| 18:27.22 | hvesalai | then you don't need the build.xml at all |
| 18:45.33 | Einzig_ | tomcat6 is also supposed to work with javaSE 6 right? |
| 18:45.58 | Einzig_ | this just continues to fail |
| 18:46.00 | hvesalai | yes |
| 18:46.49 | Einzig_ | <PROTECTED> |
| 18:46.49 | Einzig_ | import javax.servlet.*; |
| 18:47.13 | hvesalai | the error message means that when javac is compiling the code, it cannot bind the javax.servlet classes |
| 18:47.26 | hvesalai | which means you don't have the servlet-api.jar in your javac classpath |
| 18:47.34 | Einzig_ | what else can this be, but the build.xml file or the missing $CATALINA_HOME variable? |
| 18:48.17 | hvesalai | I don't think CATALINA_HOME envronment variable helps you much in this thing |
| 18:48.26 | Einzig_ | hmm |
| 18:48.47 | hvesalai | that variable is used by tomcat when it is run |
| 18:49.43 | hvesalai | so how do you compile the code? |
| 18:50.06 | hvesalai | i.e. what tool/command are you using to compile it? |
| 18:51.54 | Einzig_ | javac -classpath /path/to/tomcat/lib/servlet-api.jar:classes:. -d classes /homedir/prog/src/com/example/web/bla.java |
| 18:52.21 | Einzig_ | Not literally |
| 18:52.29 | Einzig_ | but that's the structure |
| 18:53.23 | hvesalai | you are using javac directly? |
| 18:53.44 | Einzig_ | yes |
| 18:53.54 | hvesalai | ok.. then the build.xml will do you no good |
| 18:54.01 | hvesalai | and no environment variable either |
| 18:54.48 | hvesalai | but that's good |
| 18:54.58 | hvesalai | now double check the path to servlet-api.jar |
| 19:04.33 | Einzig_ | that is correct. |
| 19:04.47 | Einzig_ | No more bin |
| 19:05.18 | hvesalai | so if you type ls -l /path/to/tomcat/lib/servlet-api.jar |
| 19:05.22 | hvesalai | you get a respone? |
| 19:05.27 | Einzig_ | yes it exists |
| 19:08.08 | hvesalai | and what does javac -version say? |
| 19:08.26 | Einzig_ | 1.6.0 |
| 19:08.29 | Einzig_ | -22 |
| 19:08.42 | Einzig_ | 1.6.0_22 even |
| 19:09.20 | hvesalai | beats me... copy-paste the whole command you are running |
| 19:11.22 | Einzig_ | src/com/example/web/BeerSelect.java:3: package javax.servlet does not exist |
| 19:11.22 | Einzig_ | import javax.servlet.*; |
| 19:11.40 | Einzig_ | javac -classpath /usr/share/tomcat6/lib/servlet.api.jar:classes:. -d classes src/com/example/web/BeerSelect.java |
| 19:11.43 | Einzig_ | src/com/example/web/BeerSelect.java:3: package javax.servlet does not exist |
| 19:11.46 | Einzig_ | my bad |
| 19:12.01 | hvesalai | ok |
| 19:12.05 | hvesalai | you still have the servlet api wrong |
| 19:12.13 | hvesalai | what is the result of running |
| 19:12.16 | hvesalai | ls -l /usr/share/tomcat6/lib/servlet.api.jar |
| 19:12.26 | hvesalai | v.s. |
| 19:12.32 | hvesalai | ls -l /usr/share/tomcat6/lib/servlet-api.jar |
| 19:12.49 | Einzig_ | That's the same file |
| 19:13.02 | Einzig_ | ah wait |
| 19:13.20 | hvesalai | the two rows are different |
| 19:13.25 | hvesalai | above is what you are referring to |
| 19:13.31 | Einzig_ | ah that's it :D |
| 19:13.39 | Einzig_ | I hate it when a typo happens |
| 19:13.52 | Einzig_ | shit, costs me hours by now |
| 19:13.58 | Einzig_ | thanks |
| 19:14.02 | hvesalai | ok... no problem |
| 19:14.12 | hvesalai | but I really would like to recommend you use some IDE such as eclipse |
| 19:14.18 | hvesalai | or at least ant (that uses the build.xml) |
| 19:14.38 | hvesalai | ofcourse those are more things to learn, but it really will pay off |
| 19:14.40 | Einzig_ | I want to know what I am doing under the hood, plus I bought this book, so I thought I'd go this way |
| 19:14.52 | hvesalai | that is cool |
| 19:14.59 | Einzig_ | besides, even the tomcat site tutorial uses the commandline |
| 19:15.25 | Einzig_ | so I figured going with Netbeans in my case, might be a bad choice |
| 19:15.29 | hvesalai | now the next challenge for you is how to make the war package |
| 19:15.37 | Einzig_ | it is for running solr |
| 19:16.09 | Einzig_ | the solr tutorial also was lacking in how to set up tomcat, so it is a bit tiresome to do tutorial after tutorial |
| 19:16.22 | hvesalai | ;-) |
| 19:16.37 | hvesalai | I don't think solr is very picky in how the tomcat is set up |
| 19:16.43 | Einzig_ | thing is: at work I did set up tomcat with netbeans |
| 19:16.55 | hvesalai | I might be wrong, but if it was, there probably then is some tutorial for it |
| 19:17.03 | Einzig_ | but I still had no idea wtf I just did (with help of a colleague) |
| 19:17.32 | hvesalai | just drop the solr war in the webapp dir and start tomcat |
| 19:18.20 | Einzig_ | I had to know how the lot was structured since I have to make solr integrate with current servlets |
| 19:18.30 | Einzig_ | and I am new to the whole servlet thing too. |
| 19:18.46 | Einzig_ | Too much to read :/ |
| 19:19.44 | Einzig_ | ( the oreilly tutorial is thus about JSP and servlets and mentions tomcat as a recommendation, but lacks in how to set that up correctly) |
| 19:19.55 | Einzig_ | Head first JSP fyi |
| 19:20.37 | hvesalai | the one proper way to set up tomcat is to just extract the .tar.gz |
| 19:20.55 | hvesalai | after that you are ready to go |
| 19:21.26 | Einzig_ | okay |
| 19:23.00 | hvesalai | that' for development |
| 19:23.10 | hvesalai | for production you really need to know more |
| 19:23.37 | hvesalai | http://tomcat.apache.org/tomcat-6.0-doc/index.html is a good place to start for that |
| 19:24.12 | Einzig_ | yep, skipped to that |
