And locate the lines below to start fine tuning Jetty's memory usage:

When trying to access a controller from the default start page. I traced this to a missing dependency in grails (I use SpringSource Tool Suite for development so that maybe the root cause). By opening and editing your /project/grails-app/conf/(default package)/BuildConfig.groovy, add the following under grails.project.dependency.resolution.

Build your war and re-deploy. Still getting an error?? I was. For jetty there was still an issue with calling the controller. After spending some time exploring, it looks like Jetty support was removed from Grails 1.2. I stumbled across a post mentioning installing the grails Jetty plugin with:

After running this, and re-building my war file and re-deploying it one final time, bingo it all worked.

As with all types of deletes, recursive or not, use with caution.

1. grails war (your app), in this case epic.war
2. Copy to server
   PLAIN TEXT
   CODE:

   1. scp epic.war user@server:/location

3. On Debian the location for jetty webapps is: /var/lib/jetty/webapps
4. Copy from upload location to the above folder (I used sudo)
5. Change permissions:
   PLAIN TEXT
   CODE:

   1. sudo chown jetty:adm epic-0-0.1.war

6. created a *.xml context file in /etc/jetty/contexts, with something like this [note case is important!!]:
   PLAIN TEXT
   CODE:

   1. <?xml version="1.0"  encoding="ISO-8859-1"?>
   2. <!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">
   3. <Configure class="org.mortbay.jetty.webapp.WebAppContext">
   4.   <Set name="contextPath">/epic</Set>
   5.   <Set name="war"><SystemProperty name="jetty.home" default="."/>/webapps/epic-0-0.1.war</Set>
   6. </Configure>

7. restart jetty :
   PLAIN TEXT
   CODE:

   1. sudo /etc/init.d/jetty restart

   (try stop/start as well)

8. test with :
   PLAIN TEXT
   CODE:

   1. lynx http://localhost:8080/epic/

9. Nice but I'd like http://localhost/epic/ so enable mod_proxy in apache if you haven't already :
   PLAIN TEXT
   CODE:

   1. a2enmod proxy

10. edit /etc/apache2/mods-enabled/proxy.load and if not present add at end:
    PLAIN TEXT
    CODE:

    1. LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so

11. edit your virtualhost conf file I am using 000-default and add:
    PLAIN TEXT
    CODE:

    1. ProxyRequests Off
    2. <Proxy *>
    3.     Order deny,allow
    4.      Allow from all
    5. </Proxy>
    6. ProxyPass        /epic http://localhost:8080/epic
    7. ProxyPassReverse /epic http://localhost:8080/epic
    8. ProxyPreserveHost On

12. restart apache : 
    PLAIN TEXT
    CODE:

    1. sudo /etc/init.d/apache2 restart

13. now you can
    PLAIN TEXT
    CODE:

    1. lynx http://localhost/epic/

Update: I had omitted the ProxyPreserveHost On from the Apache configuration, which resulted in css, images and external javascripts not loading. It also caused an issue with accessing controllers.

• Deploying a web application to Jetty

When you google for the solution I found a number of dead ends, but in the comments for one of them there was a helpful pointer.

When you do an 'ls -la' on sites-enabled (inside /etc/apache2), you will see a symbolic link to the sites-available folder and typically just for the default site (000-default -> default). However in sites-available there's also a default-ssl config file. Creating a symbolic link to this file and reloading apache fixed my problem and now I have apache serving up http over SSL .

being creative while writing code...

1. MySQL : failed to start, complaining about:
   PLAIN TEXT
   CODE:

   1. /etc/init.d/mysql: ERROR: Using expire_logs_days without log_bin crashes
   2. the server. See README.Debian.gz

   Commenting out the expire_logs_days in the my.cnf file allowed me to restart MySQL.

2. After the upgrade of Apache, my virtual hosts weren't working. A quick search via Google pointed me to this post - a quick edit of all of my host files and it was all working again.
3. the php-mysql connector somehow hadn't been upgraded/installed so a quick
   PLAIN TEXT
   CODE:

   1. apt-get install php5-mysql

   fixed that problem.

4. OpenBD : the only thing that remains broken was my tomcat5.5 Open BD install. Tomcat was working fine but Open BD refused to start up complaining about :
   PLAIN TEXT
   CODE:

   1. javax.servlet.ServletException: Open BlueDragon Engine Failed to initialise tags: java.awt.Color

   Since I am not really using it, it's not that important, but at some stage I'd like to get it working again. If you have any suggestions, please leave a comment.

The config looked fine, but after restarting the service, I still wasn't getting prompted for a log in. After re-jigging the order to what you see below and restarting the apache service (we are using 2.0.59), it all worked. Maybe this will help someone else along the way.

Oops forgot to install XCode (you always forget to install something on a new machine ). Quickly ran the XCode installer, however when I ran the command again I got a new error:

Turns out you need to do a cleanup before attempting to run the command again:

Time to continue the Mapnik install.
