How to install Laravel to a subdirectory

Simple! Just need to change a setting in the .htaccess file. I am using Laravel 4, you might be using some other version but the method should apply nevertheless. I use an alias to point to this directory.

Add this line “RewriteBase /l4″ to your .htaccess where l4 is your sub directory or folder.

[code language=”php”]<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteBase /l4
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>[/code]

Have fun!

How to run multiple applications on a single tomcat

I do this in Ubuntu 12.10 but I think it applies to Windows 7 configurations too. I wanted to run more than one application in a single instance of tomcat. I have to say this is not the best decision I have made.

You can load two apps in one server instance if you put them in different directories and have two different host names.

In my case, my two hostnames are app1.internal.kw.sg and app2.internal.kw.sg, yours will be different. You can edit your hosts here in your /etc/hosts

Both of my apps would be called app1 and app2. I put them into the corresponding directories, as specified in appBase. In my case, I placed them in:

  • /var/lib/tomcat7/app1
  • /var/lib/tomcat7/app2

You can open up your /etc/tomcat7/server.xml file. In Windows 7, it would be where ever your central tomcat configuration files are at. This is my server.xml file:

[code language=”xml”]<?xml version=’1.0′ encoding=’utf-8′?>
<Server port="8005" shutdown="SHUTDOWN">
<Listener className="org.apache.catalina.core.JasperListener" />
<Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
<Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
<Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

</Server>
[/code]

You can refer to it. Unfortunately I cannot provide much support for this.

Disadvantages

Well, this method has a key disadvantage, each time you rebuild your Java classes, you need to restart the server and it would be better to be able to restart one application at a time rather than both applications together due to a longer loading time. Most of the time you will only make changes to one application anyway. It is better to have a configuration with two servers and each of them supporting just one application. That’s my take and I learnt it the hard way.

Tomcat paths in Ubuntu 12.10

And so I have the displeasure of working with Java — a platform I once swear to avoid for the rest of my life — and I had to have my Ubuntu 12.10 environment set up. This is also verified to be similar in Ubuntu 12.04.

If you install tomcat7 from the official repository using “sudo apt-get install tomcat7”, the following paths and commands are probably helpful to you too.

Your WAR files

WAR files (.war) typically go into:

[code language=”bash”]/var/lib/tomcat7/webapps[/code]

Your log files

Your log files should be here:

[code language=”bash”]/var/lib/tomcat7/logs[/code]

It should be called “catalina.out”. It’s useful to check here for troubleshoot Apache Tomcat. It doesn’t mean that tomcat’s successful start would mean the application to be working. catalina.out has saved me on several occasions.

Your tomcat7 configuration files

Server settings goes here:

[code language=”bash”]/etc/tomcat7/server.xml[/code]

You might find the other properties files useful as well:

[code language=”bash”]/etc/tomcat7[/code]

Your tomcat7 and catalina startup shell files

You might need to edit some .sh files like in my case to change Catalina options. You can find the shell scripts here:

[code language=”bash”]/usr/share/tomcat7/bin[/code]

You can read more on setting up Catalina environment options.

Other notes

If you know of other paths worth including, do post a comment. While this is documented more for personal use, I hope you can find it useful too!

Where to find Windows Live Messenger emoticons

This is the directory or folder where MSN or Windows Live Messenger custom emoticons are located:

For Windows XP:

C:Documents and Settings [Your user name] Local SettingsApplication DataMicrosoftMessenger [Your Live ID] ObjectStoreCustomEmoticons

For Windows Vista or Windows 7:

C:Users [Your user name] AppDataLocalMicrosoftMessenger [Your Live ID] CustomEmoticons

In my case (email removed), it is found in “C:Users kahwee AppData Local Microsoft Messenger something@example.com ObjectStore CustomEmoticons”.

For Mac OS X (Snow Leopard)’s Microsoft Messenger:

/Users/ [Your user name] /Documents/Microsoft User Data/Microsoft Messenger Data/ [Your Live ID] /ObjectStore/CustomEmoticons

In my case, it is found in “/Users /kahwee /Documents /Microsoft User Data /Microsoft Messenger Data /something@example.com /ObjectStore /CustomEmoticons”

You can backup your custom emoticons by copying the directory to your flash drive or something. As far as I know, you cannot transfer Mac OS X’s Microsoft Messenger custom emoticons to your Windows’ Live Messenger and vice versa.
