CF Groovy 1.0RC (With Hibernate!)

By barneyb on July 12, 2008

I've just released 1.0RC of CF Groovy, including Hibernate support.Â You can download it, or view the demo app.Â The download includes both the demo and the runtime engine.
The big new feature is Hibernate support, of course.Â Here are a couple snippets from the demo app.Â First, the entity class:
package com.barneyb

import javax.persistence.*

@Entity
class User extends AbstractEntity [...]

Thread.setContextClassLoader Doesn't Work on CF 8.0.0

By barneyb on July 10, 2008

I know the number of CF 8.0.0 installs is probably pretty minimal compared to CF 8.0.1, but thought this was worth pointing out.Â If you use Thread.setContextClassLoader on CF 8.0.0, it raises no exception, but it doesn't actually set the ClassLoader for the thread.
I ran into this today using my CF Groovy/Hibernate integration on one [...]

Junction, from Sysinternals

By barneyb on July 9, 2008

I discovered Junction today, while looking for a way to easily test my Groovy/Hibernate integration on all three major CFML runtimes.Â It's part of Sysinternals, which is a suite of tools aimed at making Windows not suck so much.Â It's got all the low-level utilities you need to efficiently manage and monitor your Windows machines [...]

Watch Out for CFQUERYPARAM and Garbage Collection

By barneyb on July 9, 2008

In the past few months I've spent a fair amount of time doing large data transformations for a couple projects, in to and out of MSSQL databases. In both projects, I've ended up refactoring my code to eliminate CFQUERYPARAM on oft-run queries, because it seems to leak memory (yes, I have debugging disabled), as [...]

CF Groovy w/ Hibernate Sample App

By barneyb on July 7, 2008

I want to put together a little sample app leveraging CF Groovy and it's Hibernate integration, but I don't know what. From a high level, the architecture will look like this:

CFML for the view layer (the HTML templates)
CFML for the web controller (probably FB3Lite)
CFML and Groovy for the service layer (ColdSpring-managed CFC's with Groovy [...]

Fun with Classloading in Java

By barneyb on July 4, 2008

With my CF Groovy project, I've been doing a lot of Java coding of late. It's all been written in CFML, but it's mostly Java code in CFML syntax. As an aside, doing that sucks. CFML is horrible for writing anything more than the simplest Java code. But on to the [...]

CF Groovy Redux

By barneyb on July 2, 2008

I just got through significantly revamping CF Groovy so that it's CFC based, instead of all in the custom tags.Â The custom tags remain, but now you can create and manage a CF Groovy runtime instance manually, rather than letting the tags do it for you.Â This will greatly assist in production performance as the [...]

CF Groovy Takes a Nap

By barneyb on July 2, 2008

After close to two weeks of struggling, I finally managed to deploy pure source to a CFML runtime (Railo, in this case), and get Groovy entities in and out of the database with Hibernate.Â No compliation, no IDE, no development-mode server, just my Groovy source along with a hacked up CF Groovy.Â This is very [...]

Railo 3 Beta 2

By barneyb on June 27, 2008

Railo dropped a second beta last night. Get it here. They've also added a WAR download, though it only works when installed into an existing "express" installation. Hopefully that'll get addressed for the next release.
A couple shining points about the runtime:

Array and Struct literals (the [...] and {…} notation) are expressions, exactly [...]

Closures for Java

By barneyb on June 26, 2008

Wanting some light reading for this evening, I decided to dig into the Closures for Java draft spec (homepage).
Oh. My. God.
I'm a huge fan of closures. They're elegant, simple, and easy to use. Their semantics are subtle, but not confusing. They allow for very concise implementation of otherwise complicated algorithms, [...]
