Use IBM JRE 7 with Tomcat 7 on Windows 7

If you have running Apache Tomcat on Windows you'll most likely run it on Oracle JVM.
What if you need to run Tomcat on IBM JRE?
You can use Apache Service Manager application to change the settings of JRE.
Open Apache Service Manager, goto Java tab.
There you see "Java Virtual Machine" field. My current value for Oracle JRE is  "C:\jre6\bin\client\jvm.dll".
Change it to file jre\bin\j9vm\jvm.dll.
Press apply.
Start Tomcat.
In your server status you can check that Tomcat is running on IBM JRE.
