Project Description
This Windows Azure Tomcat Solution is designed in a way that you can update your Tomcat project outside VS2010 project. This project is based on Startup task in which Tomcat, Java and your project is downloaded from Azure Storage and then installed in Azure VM.


Here are the highlights about this solution:

  1. You will host your Java Run-Time, Tomcat and your own solution in a ZIP file at Windows Azure Blob Storage
    1. Be sure to modify tomcat\conf\server.xml to user correct HTTP and HTTPS port as well as SSL certificate which you are going to use.
  2. Create a simple Windows Azure Worker Role Project 
  3. Add HTTP and HTTP endpoint along with Certificate which you are going to use for SSL
  4. Create a Startup task in Worker Role 
  5. In the Startup task we will do the following 
    1. Using Azureblobdownloader ( tool we will download Tomcat, Java and your project from Azure Storage to Azure VM
    2. After that we unzip these files 
    3. Then we setup Tomcat and Java environment variables as below
      1. > set JRE_HOME=%ROLEROOT%\approot\apache-tomcat-7.0.19\jre7
      2. > set CATALINA_HOME=%ROLEROOT%\approot\apache-tomcat-7.0.19
    4. After it will launch the Tomcat startup process using:
      1. > tomcat\bin\startup.bat
  6. Finally we edit workerrole.cs OnStart() function to included HTTP and/or HTTPS endpoint as below:


        public override bool OnStart()
            // Set the maximum number of concurrent connections 
            ServicePointManager.DefaultConnectionLimit = 12;

            // For information on handling configuration changes
            // see the MSDN topic at

            TcpListener TomcatPortListener = new TcpListener(RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["TomcatWeb80"].IPEndpoint);
            Trace.WriteLine(RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["TomcatWeb80"].IPEndpoint.ToString(),"IP Address:Port");

            return base.OnStart();

The Startup.bat looks like as below:


@REM Setting up Azure Stroage Credentials
set azurestoragename=happybuddha
set azurestoragekey=***********************AZURE-STORAGE-KEY**************==
set storagecontainername=xyz

@REM Download Tomcat ZIP
startup\packagedownloader.exe "%azurestoragename%" "%azurestoragekey%" "%storagecontainername%" "%filename%"
