To run your Grails application<\/a> on SSL, firstly you need to configure the Tomcat server.<\/p>\n

Here in this example, I will show how to configure Tomcat instance and run Grails\/Java application.<\/p>\n

For SSL\/HTTPS:<\/p>\n

    \n
  1. We need .keystore<\/strong> file. You can generate it by using command\u201ckeytool<\/strong><\/span> -genkey\u201d. <\/strong><\/span>Run this command<\/span> on linux terminal or window cmd,<\/span> follow<\/span> the<\/span> instructions. Fill the desire information and it will generate the .keystore file on following path: <\/span>Linux: \/<\/span>home\/[user]\/.keystore <\/strong><\/span>file <\/span>Window: <\/span>\/Documents<\/strong><\/span> and<\/strong><\/span> Settings\/[user]\/.keystore<\/strong><\/span><\/li>\n
  2. One thing you would have to remember is the password that is used while generating the <\/span>.keystore<\/strong><\/span> file because this password will be used in configuring Tomcat server instance<\/span><\/li>\n
  3. After the generation of .keystore file, copy .keystore file to webapp of tomcat directory.<\/li>\n
  4. Then open server.xml of Tomcat from conf\/server.xml and uncomment ssl port connector which is like<\/li>\n<\/ol>\n

    <\/p>\n

    [xml]
    \n&lt;Connector port=&quot;8443&quot; protocol=&quot;HTTP\/1.1&quot; SSLEnabled=&quot;true&quot;
    \n maxThreads=&quot;150&quot; scheme=&quot;https&quot; secure=&quot;true&quot;
    \n clientAuth=&quot;false&quot; sslProtocol=&quot;TLS&quot; keystoreFile=&quot;webapps\/.keystore&quot;
    \nkeystorePass=&quot;password-of-.keystore-file&quot; \/&gt;
    \n[\/xml]<\/p>\n

     <\/p>\n

    Add following<\/span> line<\/span> keystoreFile=”webapps\/.keystore”<\/span> & keystorePass=”<\/span>password-of-.keystore-file<\/span>“<\/span><\/p>\n

    Here keystoreFile<\/strong> is the location of .keystore file, and keystorePass <\/strong>is the password which initially used for creating .keystore file.<\/span><\/p>\n


    \n<\/span><\/p>\n

    5. Now SSL has been configured on Tomcat<\/strong><\/p>\n

    6. Now configure your web application as SSL enabled. If you are working on Java application,\u00a0 add the following lines in web.xml file of your web application<\/p>\n

    [xml]
    \n&lt;security-constraint&gt;
    \n\t\t&lt;web-resource-collection&gt;
    \n\t\t\t&lt;http-method&gt;GET&lt;\/http-method&gt;
    \n\t\t\t&lt;http-method&gt;POST&lt;\/http-method&gt;
    \n\t\t\t&lt;url-pattern&gt;\/*&lt;\/url-pattern&gt;
    \n\t\t&lt;\/web-resource-collection&gt;<\/p>\n

    \t\t&lt;user-data-constraint&gt;
    \n \t\t&lt;transport-guarantee&gt;CONFIDENTIAL&lt;\/transport-guarantee&gt;
    \n \t\t &lt;\/user-data-constraint&gt;
    \n \t&lt;\/security-constraint&gt;
    \n[\/xml]<\/p>\n

    If you are working on grails application, you need to run following command to generate the web.xml file because grails framework does not contain any web.xml file and web.xml file automatically generated when you are creating war file<\/span><\/span><\/p>\n

    Run following command to get web.xml file in your grails application<\/span><\/span><\/span><\/p>\n


    \n<\/span><\/span><\/span><\/p>\n

    grails install-templates<\/strong><\/span><\/span><\/p>\n


    \n<\/strong><\/span><\/span><\/p>\n

    web.xml file will be generated on the following location of your grails application \/src\/templates\/war\/web.xml<\/strong><\/span><\/span><\/p>\n

    Then add above mentioned snippet in web.xml<\/strong>, create the war file and deploy on tomcat server.<\/span><\/span> Now your application will successfully run on SSL. You can access your application using following URL: https:\/\/localhost:8443\/<application-name><\/span><\/strong><\/span><\/span><\/p>\n


    \n<\/span><\/strong><\/span><\/span><\/p>\n

    If you are working on grails application,you need to run following command to generate the web.xml file because grails framework does not contain any web.xml file and web.xml file automatically generated when you are creating war file<\/span><\/span><\/p>\n

    Run following command to get web.xml file in your grails application<\/span><\/span><\/span><\/p>\n

    grails install-templates<\/strong><\/span><\/span><\/p>\n

    web.xml file generated on following location of your grails application \/src\/templates\/war\/web.xml<\/strong><\/span><\/span><\/p>\n

    Then add above mention snipplet in web.xml<\/strong>, create the war file and deploy on tomcat server.<\/span><\/span><\/p>\n

    Now your application will successfully run on SSL <\/span><\/span><\/p>\n

    Access your application using following url’s:<\/span><\/span><\/p>\n

    https:\/\/localhost:8443\/application-name<\/span><\/strong><\/span><\/span><\/p>\n
