Confirming ColdFusion's Java version, via admin, vars, or code
Note: This blog post is from 2021. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.Have you ever wished you could confirm with 100% certainty what Java version is in use by the CF instance you are running? Or where the JVM's location is (in case you are told to modify files related to it)?
Some good news is that ColdFusion offers simple ways/variables that can show you each of these, via the admin or via CFML code. In this post, I discuss both approaches, including a simple single variable which works in CF2018 and above, a variation for those on CF2016 and earlier, as well as variations for Lucee.
