Installing Tomcat on Mac OS X

Installing Tomcat on Mac can be done in three steps. Following the steps below you can have tomcat running on your Mac in no time.

 Step 1: Download and Install Tomcat Binaries
Download the most recent stable build of Tomcat from an Apache project mirror site. Unzip the binaries into a simple location (I did it in /Users/username/Documents).  By default, the unpacked folder name will be something like "apache-tomcat-x-x-xx".  I recommend changing it to "tomcat" for ease of use.

Step 2: Configure the env variables

 For our purpose we need to set up JAVA_HOME and CATALINA_HOME variables. Setting up these variables will ensure we don't have to use the complete path name.

To set the variables, open a new Terminal window and use the following command to open the system profile for editing.

vi ~/.profile

Once you've opened the profile, add the following lines to set the JAVA_HOME and CATALINA_HOME variables:

export JAVA_HOME=/Library/Java/Home
export CATALINA_HOME=/Path/To/Tomcat/Home

Step 3: Time to start Tomcat

Start Tomcat by navigating to the "bin" folder and executing "startup.sh" from the command line.  After running the script,  you can test if Tomcat has been successfully installed by visiting http://localhost:8080 on your machine.  If the installation was successful, your browser should display the Tomcat Welcome Page.

If you receive a permissions error, use the following command to allow access to all of the Tomcat shell scripts:

chmod 755 /Path/To/Tomcat/Bin/*.sh

Try to access the link again.

Geospatial queries in MongoDB - Part 2 : {"err": "location object expected, location array not in correct format" "code": 16804}

In my last post we saw we had to create a geospatial index on the " pos " field as follows: > db.foodtrucks.ensureIndex({pos:"2d"}) However, when executing the command above we get the following error:   > db.foodtrucks.ensureIndex({pos:"2d"}) {     "createdCollectionAutomatically" : false,     "numIndexesBefore" : 3,     "ok" : 0,     "errmsg" : "location object expected, location array not in correct format",     "code" : 16804 } After some further investigation I realized that we had some documents which didn't had any latitude/longitude information. Due to this some of the documents looked like this: {     "_id" : ObjectId("53d07bf1e3e11dacc21056a8") ,     "locationid" : 437222 ,     "Applicant" : "Natan's Catering" ,     "FacilityType" : "Truck" ,     "cnn" : 188101 ,     "Locatio...

Remove and ignore files like .DS_Store, .classpath so that it doesn't get added to your github repo

When promoting code on github it is usually a good idea not to promote files like .DS_Store. .classpath etc. To accomplish this you can include a .gitignore file in your first commit . Git uses it to determine which files and directories to ignore, before you make a commit. Here is what my .gitignore looks like: /.buildpath /build/ */archive/ # Compiled source # ################### *.com *.class *.dll *.exe *.o *.so   .project .settings .classpath # Packages # ############ # it's better to unpack these files and commit the raw source # git has its own built in compression methods *.7z *.dmg *.gz *.iso *.jar *.rar *.tar *.zip # Logs and databases # ###################### *.log *.sql *.sqlite # OS generated files # ###################### .DS_Store .DS_Store? ._* .Spotlight-V100 .Trashes ehthumbs.db Thumbs.db Icon?     Alternatively, you can create a global .gitignor...
