SSL-ApacheTomcat

Some applications don't work correctly with security-constraint and have to force push Http to Https requests This include simply bit different way to complete Http to Https Issue

Generate your SSL Cetificates

Copy these files in to secured path in the server

Edit your server.xml File

Located in apache-tomcat > conf > server.xml

<Connector URIEncoding="UTF-8" port="80" acceptCount="100" enableLookups="false" maxThreads="150" redirectPort="443" />

<Connector port="443" protocol="org.apache.coyote.http11.Http11NioProtocol"
               maxThreads="150" SSLEnabled="true">
        <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />
        <SSLHostConfig>
            <Certificate certificateKeyFile="/usr/local/xxx/xxx.key"
                         certificateFile="/usr/local/xxx/xxx.crt"
                         certificateChainFile="/usr/local/xxx/xxx.crt"
                         type="RSA" />
        </SSLHostConfig>
</Connector>

Add the following element into <Host name="localhost" ...> at last

<Valve className="org.apache.catalina.valves.rewrite.RewriteValve" />

Edit you web.xml File

Located in apache-tomcat > conf > web.xml

To force Tomcat to redirect and revert all requested HTTP traffic over to HTTPS, configure the conf/web.xml file with the below block. This should be placed at the very end of the file near and above the ending </webapp> tag:

<security-constraint>
   <web-resource-collection>
   <web-resource-name>Protected Context</web-resource-name>
        <url-pattern>/*</url-pattern>
        <!--<url-pattern>/adportal/*</url-pattern>-->
   </web-resource-collection>
   <user-data-constraint>
   <transport-guarantee>CONFIDENTIAL</transport-guarantee>
   </user-data-constraint>
</security-constraint>

======Try restarting Apache-tomcat server========

Some applications don't work correctly with that security-constraint, so I followed a completely different approach:(It's Working on apache-tomcat 9)

Create the file conf/Catalina/localhost/rewrite.config

Sample is attached with this

======Try restarting Apache-tomcat server again It should work ======

===================GOOD LUCK=================
