Java – Deploying Multiple Spring Boot Web Applications in Single Server

With ASP.Net 1.1, first you have to set the runat attribute on the title markup :

<title id="PageTitle" runat="server">WebForm1</title>

Then from the code behind :

C#

// We need this name space to use HtmlGenericControl
using System.Web.UI.HtmlControls;

namespace TestWebApp
{

      public class WebForm1 : System.Web.UI.Page
      {
            // Variable declaration and instantiation
            protected HtmlGenericControl PageTitle = new HtmlGenericControl();

            private void Page_Load(object sender, System.EventArgs e)
            {
                  // Set new page title
                  PageTitle.InnerText = "New Page Title";
            }
      }
}

VB

Imports System.Web.UI.HtmlControls

Namespace TestWebApp

    Public Class WebForm1
        Inherits System.Web.UI.Page

        Protected PageTitle As HtmlGenericControl = New HtmlGenericControl()

        Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

            PageTitle.InnerText = "New Page Title"
        End Sub

...

    End Class
End Namespace

The chapter Packaging executable jar and war files in the Spring Boot reference documentation states:

To build a war file that is both executable and deployable into an external container you need to mark the embedded container dependencies as “provided”, e.g:

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
