How to Install Certificate Enrollment Web Service

After my previous post on How to Install Certificate Services on Windows Server 2008 R2.

You’ve now got a Certificate Authority- Root CA, that is capable of issuing certificates to your servers and users.  You can go back through the wizard and install additional CA components, for example, that will allow you to issue certificates to users and computers that are/are not part of your domain.  That option is called ‘Certificate Enrollment Web Service’. Go through the following steps:

1.       Select Add Role Services from the Active Directory Certificate Services Role. Wizard will guide you through.

2.       From the Select Role Services choose Certificate Enrollment Web Service, Certificate Enrollment Policy Web Service and click Next.

Select Role Services

3.       For Specify CA for certificate Enrollment Web Services; leave the default CA settings (i.e. CA name), Next

Specify CA for certificate Enrollment Web Services

4.       Select Windows Integrated Authentication Type, Click Next

How to Display Custom Error Page on Tomcat 6

If you are Unhappy with the default error pages that come with Tomcat then You can define your own custom error pages in your web.xml file after the following tag:

<welcome-file-list>

<welcome-file>index.html</welcome-file>

</welcome-file-list>

In the example shown below, i define 2 html pages — web_server_error_500.html and file_not_found_404.html which will be displayed when the server encounters an error 500 or an error 404 respectively. Put your html files on tomcat6.0/webapps/Root folder.  And add this code on web.xml file.

<error-page>

<error-code>500</error-code>

<location>/web_server_error_500.html</location>

</error-page>

<error-page>

<error-code>404</error-code>

<location>/file_not_found_404.html</location>

</error-page>

Please be aware that the order of the tags for the web.xml file is very important. If the order in your web.xml file is incorrect, Tomcat will output errors on startup.

And for Internet Explorer users be sure you have enabled “Show custom error pages” from Internet Options>Advanced tab.

How to Configure Tomcat 6 – Custom Default Pages

Tomcat uses the same convention as the Apache Web Server in that index.html is

the default or home page of any directory. Sometimes you may want to change that

to homepage.html or maybe a JSP page, like home.jsp.

To do that, simply open the web.xml of your web application, and add the

following lines without commenting :

<welcome-file-list>

<welcome-file>home.jsp</welcome-file>

<welcome-file>homepage.html</welcome-file>

<welcome-file>index.html</welcome-file>

</welcome-file-list>

To change it system-wide, edit the global web.xml in $CATALINA_HOME/conf, and

change the to point to the file of your choice.

How to Redirect all http requests to https on Tomcat by default

***Considering that you already enable SSL with proper certificate.

To auto redirect all of your webserver requests from http to https just paste the following to your tomcat installation folder\conf\web.xml file and restart the service.

<security-constraint>
<web-resource-collection>
<web-resource-name>Protected Context</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<!– auth-constraint goes here if you requre authentication –>
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>

Now browse http://localhost and it will automatically go to https://localhost , for example.
