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
   
   ./run

   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:
   
   
    http://developer.android.com/tools/devices/index.html
   
   
    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"   
      URIEncoding="UTF-8"   
      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.
  
  AUTHBIND=yes

• 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:

<repository>
      <id>maven2-repository.dev.java.net</id>
      <name>Java.net Repository for Maven</name>
      <url>http://download.java.net/maven/2/</url>
      <layout>default</layout>
</repository>
