If you run an online retailer, your site might be creaking under the load of millions of last-minute shoppers gobbling up your products.  What's that?  Time for some quick load tests to find those slow queries!  This sounds like a job for FusionReactor's monitoring, profiling, and debugging-- the best gift you can give a server this year as part of our 12 Tips of (CommandBox) Christmas.

FusionReactor

FusionReactor is a popular tool for monitoring performance and gathering metrics for ColdFusion and Java J2EE applications. You may with to use FusionReactor with the servers you start up via CommandBox. We've created a CommandBox module that will add FusionReactor support to your CommandBox servers which you can view here on ForgeBox.
https://www.forgebox.io/view/commandbox-fusionreactor

Installation

The CommandBox FusionReactor module is a separate project that you can optionally install by typing this:

CommandBox> install commandbox-fusionreactor

That's it-- now every server you start with the start command will automatically have the JVM args added to it to load up FusionReactor.

Usage

There's nothing special you have to do in order for FusionReactor to load. A random port will be chosen for FusionReactor to use so you can have more than one server running at a time and each of them will have their own FusionReactor instance running. When you start a server, you should see some output similar to this:

******************************************
* CommandBox FusionReactor Module Loaded *
******************************************

FusionReactor will be available at the URL http://127.0.0.1:2871

To open FusionReactor in your browser, you can run the following command:

CommandBox> fr open

If you right click on the tray icon for this server, you'll see there is a new menu item at the bottom called Open Fusion Reactor that will do the same thing.

Licensing

FusionReactor is a commercial product and requires a license to use. If your company has a license for you to use on your PC, then you can register your CommandBox FusionReactor licence with this command:

CommandBox> fr register "myLicenseKey"

If you don't have a license, you can sign up for a trial and purchase a license from the FusionReactor website.

Introducing the BoxLang Spring Boot Starter: Dynamic JVM Templating for Spring

Spring Boot developers know the pain of evaluating view technologies. Thymeleaf is great — until you need more expressiveness. FreeMarker is powerful — until the syntax fights you. What if you could write templates in a dynamic JVM language that gives you the full power of the platform, feels natural, and requires zero setup to integrate?

Meet the BoxLang Spring Boot Starter.

Why Swiss Banks Are Modernizing CFML Platforms Without Rewrites

The growing need to evolve legacy financial platforms safely

These systems manage a wide range of functions, including:

  • internal banking workflows
  • reporting systems
  • client portals
  • data integration platforms
  • compliance and risk management tools

In many cases, thes...

Reactive vs Proactive ColdFusion Support: Why Waiting for an Outage Is the Most Expensive Strategy

Reactive vs Proactive ColdFusion Support: Why Waiting for an Outage Is the Most Expensive Strategy

Many ColdFusion environments operate in a reactive mode without realizing it.

Everything seems fine… until something breaks.

A server crashes.

Performance drops suddenly.

An integration stops working.

A security audit reveals missing patches.

At that point the response is urgent:

“Can someone help us fix this now?”

Emergency support is sometimes unavoidable. But when reactive intervention becomes the norm, it usually means something deep...
