RE: Memory question

Thank you all!  I set JAVA_OPTS in the tomcat startup and it works!

Now to figure out the next problem, but that's an issue with the
application I'm running and not Tomcat.

  I believe the startup script accepts extra parameters and just
  passes them on to the JVM for startup.  You should be able to do:
 
  startup.sh -Xmx512m
 
 Unfortunately not, although it certainly would be convenient.  The extra 
 parameters are passed to Tomcat's Bootstrap class, not the JVM.  You really 
 do have to use CATALINA_OPTS or JAVA_OPTS.

Down the rabbit hole with JDBC

2008-07-24 Thread Matt Burkhardt 
Sorry - I've been slogging through this...

Anyway, I'm trying to get an application working, but all of their
documentation talks about is tomcat5.5 and I've got tomcat6

I have gotten the latest Connector/J binary from MySQL and installed in
into tomcat/lib but I would like to test it.  So, I went to

http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html

and followed the instructions to set up a DBTest - but I get this

HTTP Status 500 -

Re: Down the rabbit hole with JDBC

2008-07-24 Thread Matt Burkhardt 
Thanks - it was the first - I just had the files in the WEB-INF
directory - not in the lib

Is there some method for finding errors / logs?  Right now, I'm trying
to get an application running, and I'm just guessing.  For example, my
catalina.log file says

INFO: The listener org.alfresco.web.app.ContextListener is already
configured for this context. The duplicate definition has been ignored.
Jul 24, 2008 3:46:11 PM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
Jul 24, 2008 3:46:11 PM org.apache.catalina.core.StandardContext start
SEVERE: Context [/alfresco] startup failed due to previous errors

Where can I go to find out what's causing this?

 This isn't a JDBC error as much as it's a taglib error.  You are trying 
 to use JSTL taglibs in your web application and tomcat can't find the 
 libraries that contain the taglib.  Things to check:
 
 1. standard.jar and jstl.jar are in the webapp's WEB-INF/lib directory 
 -- at least for jstl 1.1.  I believe jstl 1.2 consolidated things into 
 one jar file.
 
 2. The webapp's docBase is not the same as the Host ... element's 
 appBase attribute in server.xml.  This has already bitten one person on 
 the list today.

 You seem to be expecting us to guess the Tomcat version you're using.


Sorry about that - I'm usually much better - it's version 5.5

 
  First, I have several error messages in the catalina log that
  reference applications that I have removed from my web site.
 
 What are the messages?  Have you cleaned out Tomcat's work directory?  Do you 
 have now-useless Context elements in conf/Catalina/[host]/[appName].xml 
 files?

The error messages - I've been installing and uninstalling several
packages.  This is just one of them -

Jul 22, 2008 9:38:33 AM org.apache.catalina.core.StandardContext
resourcesStart
SEVERE: Error starting static Resources
java.lang.IllegalArgumentException: Document
base /opt/dspace/webapps/jspui does
 not exist or is not a readable directory

Work directory?  Wow, I finally found the symbolic link and was able to
find the elements and delete them.  Wow - this is one difficult system
to understand!



 
  Also, I would love to be able to run the admin, but I have a headless
  server so I need to access /manager from a remote machine.  I haven't
  been able to find the documentation for that.  Any ideas?
 
 The links are on Tomcat's default home page; if you've replaced that, it's 
 normally
http://[siteName]/manager/html
 for the manager app, and can be reached from any device that can reach the 
 server.

I installed Tomcat to run on another port...

Okay - I have http://[myserver]:8180/manager/html and all I getis a
blank page - no error, no nothing


 
  - Chuck
 

Thank you, Chuck.  At least I'm able to get rid of the error messages
from the missing apps so I can track down my other problem!

Memory question

2008-07-23 Thread Matt Burkhardt 
Okay - I've gone ahead, uninstalled the distro from Ubuntu, installed
Tomcat 6.0.16 and I'm having problems running out of memory.  My
catalina.out file contains the lines

at
org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:288)
at
org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413)
Caused by: java.lang.OutOfMemoryError: Java heap space
 
and the application says it needs 512MB, I have 1GB on the server and it
says that you can use up to 70% of the memory before it gets starved.
So I edited the /etc/environment contents and ended up with this

more /etc/environment
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
ANT_HOME=/usr/share/ant
JAVA_HOME=/usr/lib/jvm/java-6-sun
JAVA_OPTS=${JAVA_OPTS} -Djava.awt.headless=true -Xms512M -Xmx512M
-XX:PermSize=256M -XX:MaxPermSize=256M

and I rebooted the machine, but I'm still getting the error.  I don't
know how to check and see if it took the arguments correctly, but when I
look at http://myserver:8080/manager/status I see

JVM

Free memory: 23.34 MB Total memory: 63.56 MB Max memory: 63.56 MB

What am I doing wrong?

Uninstalling Applications

2008-07-22 Thread Matt Burkhardt 
Hi all,

I'm having a few problems - so I'm trying to get rid of error messages
during start up and shut down to try and track down the issue.

First, I have several error messages in the catalina log that reference
applications that I have removed from my web site.  How do I prevent
them being loaded up during start of tomcat5.5?

Also, I would love to be able to run the admin, but I have a headless
server so I need to access /manager from a remote machine.  I haven't
been able to find the documentation for that.  Any ideas?

Thanks,
