Here’s a recipe I found useful for trouble-shooting a web-app over an SSL connection. The steps involved are to:
Set the server name/IP on each of the testing machines (both Windows and Linux)
Create a self-signed certificate for the server using the java-based keytool
Export the certificate for installation as a CA in the clients
Configure JBoss AS7 to use the certificate sotre
All the above steps are sufficiently simple, but each required it’s own share of googling to get everything just right. This post is as much a set of notes to myself in the future, as it is a blog
1. Setting the Server name
On your Linux testing machine, make sure the sure IP and name of your local server are in your /etc/hosts file:
127.0.1.1 bleathem-redhat bleathem-redhat.local
Do the same thing for you windows clients - that’s right! Windows has a /etc/hosts file! See this wikipedia article to locate the file in your version of windows.
2. Create a self-signed certificate
Use the java keytool command to create the certificate store:
keytool -genkey -alias tomcat -keyalg RSA -validity 3650 -keystore server.jks
when asked for your “first and last name”, answer with the fully-qualified domain name. For me this is bleathem-redhat.local.
3. Export the certificate
Export the certificate from the keystore you just created, again using the keytool command:
bashkeytool -exportcert -alias tomcat -keystore server.jks -file as7.cer
Copy this certificate to your Windows clients, and install it as a certificate authority. I found this to be necessary, as IE9 is particularly nasty about dealing with “unofficial” certificates. Steps to do this are left as an exercise for the reader! (I don’t feel like taking a bunch of windows screenshots.)
4. Configure JBoss AS7
In the standalone.xml configuration file of your AS7 instance, find the line:
<connector name="http" protocol="HTTP/1.1" socket-binding="http" scheme="http"/>
And add below it the lines:
<connector name="https" protocol="HTTP/1.1" socket-binding="https" scheme="https" secure="true"> <ssl name="https" password="changeit" certificate-key-file="standalone/configuration/server.jks"/> </connector>
This will configure your AS 7 instance to use your newly created certificate store on it’s SSL enabled port. The default https port for AS7 is 8443.
And there we have it! A fully functional SSL/https enabled environment for testing our web apps!
