| 11:39.23 | Jimmetry | Hi guys |
| 11:40.43 | Jimmetry | Been working on a webapp since yesterday and it all works... but only if Java's environment variables are correct |
| 11:40.56 | Jimmetry | Otherwise it tells me the Servlet class doesn't exist (error 500) |
| 11:41.15 | Jimmetry | The strange thing is... the examples that come with Tomcat work fine under any circumstances |
| 11:41.46 | Jimmetry | Any idea what the difference could be? i.e. something in a settings file somewhere that I could add |
| 11:52.16 | rtk126 | Jimmetry: What do you mean by "only if Java's environment variables are correct"? Which variables JAVA_HOME? |
| 11:52.34 | haxplorer | which is the tomcat developers channel? |
| 11:53.43 | rtk126 | Anyone can help with Replication? |
| 11:53.44 | Jimmetry | rtk126: Not quite sure to be honest, but I think so. Tomcat's scripts don't seem to work properly on the Mac... |
| 11:54.00 | Jimmetry | If I manually set them, it works |
| 11:54.09 | Jimmetry | I'm just wondering why the example webapps work either way |
| 11:54.26 | rtk126 | Jimmetry: Those must be set inorder to the start script to find and execute Java. So you would need to wrap it, or add it to your environment on login |
| 11:54.56 | rtk126 | So Tomcat does start, but your application crashes? |
| 11:55.35 | Jimmetry | rtk126: Yep. Servlet class apparently doesn't exist when i try to run one of mine |
| 11:55.43 | rtk126 | It's not Tomcat for Mac that doesn't work, it's the configuration on your computer... |
| 11:55.52 | Jimmetry | Works if I manually set env vars and works on Windows either way |
| 11:55.53 | rtk126 | What's the JAVA_OPTS you're using? |
| 11:56.10 | Jimmetry | rtk126: Hmm... appears to be empty |
| 11:56.31 | rtk126 | You do export JAVA_OPTS="" ? |
| 11:56.49 | Jimmetry | No, I don't touch it |
| 11:56.59 | rtk126 | Which one you set manually? |
| 11:57.10 | Jimmetry | CATALINA_HOME and CLASSPATH |
| 11:57.28 | rtk126 | And what do you put in CLASSPATH? |
| 11:57.54 | rtk126 | Have you looked at the log for the time you get the 500 error? |
| 11:58.10 | Jimmetry | "/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Classes/classes.jar:$CATALINA_HOME/common/lib/servlet-api.jar" |
| 12:01.01 | rtk126 | I am not an expert, but it sounds like it does not find the servlet API. You need to either create a wrapper script that will set the variables, or add those to your login file |
| 12:01.44 | Jimmetry | I know that it's an issue with the script... that's no big deal. I was just wondering why the examples work |
| 12:01.47 | Jimmetry | It's ok |
| 12:02.02 | Jimmetry | According to a friend who tested it, it all works with default configs in Windows and Linux |
| 12:05.14 | rtk126 | That is not completely true... It depands on your Linux dist.... |
| 12:06.05 | Jimmetry | rtk126: Of course... but basically my issue here is that I need to submit this as an assignment, and if it doesn't work with a run-of-the-mill install of tomcat and derby then I have problems |
| 12:07.51 | rtk126 | Don't know what to tell you... It's like saying I need to submit a web-site, if it doesn't work when the computer does not connect to the internet I will have problems... You're underlining executors must be set properly.. This includes the OS, Java and yes, Tomcat... |

| 14:13.42 | MHSL | any log that you have |
| 14:14.17 | rtk126 | That's the page I've used for the JMX, but I got a blank page.. let me read it again |

| 14:15.21 | rtk126 | OK, I guess I don't understand how JMX works... I've used a browser... |
| 14:15.57 | MHSL | ... |
| 14:16.01 | MHSL | you need a jmx client |
| 14:32.26 | rtk126 | MHSL: I've tried to run the com.example.Main, but I get port already in use... Shouldn't the client connect to the port? |
| 14:32.59 | MHSL | where is that from? |
| 14:33.33 | MHSL | if you have gui you can use jconsole to connect, if not use command line jmx client |
| 14:34.28 | rtk126 | I don't have X... I guess the MAIN does not need to run, it's running from the Tomcat, right? |
| 14:34.47 | MHSL | what are you talking about? |
| 14:35.07 | MHSL | tomcat will listen on a port for jmx, then you use a jmx client to connect to that port |
| 14:36.16 | rtk126 | OK, now I get authentication error... Do I need to setup the client like the server (-Dcom.sun.... )? |
| 14:39.06 | rtk126 | OK, found it |
