Update the JRE on Railo

Railo's Excellent guide link is below, but for my reference; to summarize


1) Download the most current JRE (Which at the time of this blog post was Java SE 7u21)

http://www.oracle.com/technetwork/java/javase/downloads/index.html

2) Install it to an easy to remember folder, such as C:\jre\

3) Stop the Tomcat Railo service ( while it is not busy )

4) Rename Railo's JDK folder:  railo/jdk   --> railo/jdk_old   ( In my case, C:\railo\jdk )

5) Make a new railo/jdk folder

5) Copy the contents of C:\jre  from step 2 into the railo/jdk folder

6) Restart Tomcat Railo & Test your world. You can display the jre version in coldfusion via:

<cfoutput>#CreateObject("java", "java.lang.System").getProperty("java.version")#</cfoutput>

7) Recycle railo/jdk_old
