Solve&Fix "Package name must look like" error in Phonegap 3

You may get "Package name must look like..." error if you create a phonegap 3 project as below:

cordova create ./hello-world HelloWorld
cordova platform add android

When you run above code, you get below error:

Checking Android requirements...
Creating android project...
[Error: An error occured during creation of android sub-project. 
Package name must look like: com.company.Name

You get error because you are missing --id and --name options. The correct way to add Android support into your Phonegap application would be as follows:

phonegap create ./hello-world --id com.example.hello --name HelloWorld
cd hello-world
cordova platform add android

How to Create&Develop a Phonegap HelloWorld Project

  1. Install PhoneGap. You need NodeJs package manager installed.

    npm install -g cordova
  2. Create  a project named "HelloWorld" inside "phonegap-example" directory. Use "com.example.hello" root package.

    phonegap create phonegap-example --id com.example.hello --name HelloWorld
  3. Add android support

    cd phonegap-example
    cordova platform add android

  4. Build the project

    cordova build

  5. Run the project. You need Android Development SDK installed.

    cd ./platform/android/cordova
    In case, you don't have an android emulator defined in your development environment, you may get following error:

    ERROR : No emulator images (avds) found, if you would like to create an  avd follow the instructions provided here:
     Or run 'android create avd --name <name> --target <targetID>' in on the command line.

How to Bind Port 80 to Tomcat 7 in Ubuntu

Default tomcat installation uses 8080 port. This is not preferred way when you present your web application over a top-level domain. I needed this information for my new sites gamenism.com/game and onlineuml.net/modeler. Below I am describing how to bind port 80 to Tomcat 7.
  • Backup /var/lib/tomcat7/conf/server.xml
  • Open /var/lib/tomcat7/conf/server.xml for editing. Find the part beginning with "<Connector"
    As highlighted below, change the value of port attribute to 80.

    <Connector port="80" protocol="HTTP/1.1"    connectionTimeout="20000"   
        redirectPort="8443" />
  • Backup /etc/default/tomcat7 file
  • Open /etc/default/tomcat7 file for editing. 
    • Find the line containing "AUTHBIND" property. This line should be commented. Uncomment it.
    • Set AUTHBIND property to YES. This is required to bind a port to a process which is less than 1023.

  • Restart tomcat 7

    sudo /etc/init.t/tomcat7 restart

How to Download Sun Jars in Maven Projects

Sun jars cannot be hosted in Maven central repository due to Sun's Binary License, e.g:

  • javax.sql:jdbc-stdex
  • javax.transaction:jta
  • javax.activation:activation

java.net provides a Maven repository to access Sun jars. It is a good practice to add following repository in your settings.xml file:
      <name>Java.net Repository for Maven</name>

More details can be found at:
