Just a quick tip in case anyone encounters the following exception when using MyBatis
IncompleteElementException: Could not find result map XXXX.hashmap
Where XXXX is the namespace of your mapper. You probably made a typo and uses resultMap=”hashmap” instead of resultType=”hashmap”
In case anyone is interested in running an embedded OrientDB instance in Apache Karaf, here’s a feature to install: https://gist.github.com/rkettelerij/7427673
Top-down or bottom-up architecture? -
Slides of my talk at the Agile Software Architecture Symposium 2012 in Elst.
In my last blog I talked about exploring Kotlin, a JVM language in development by JetBrains. In this blog I’ll walk through a larger piece of Kotlin code.
The program we’re talking about is a simple spell checker. It reads a dictionary of words from a file (/usr/share/dict/words) into a set. Then it reads a sentence from stdin and checks if every word is in the dictionary. Finally it informs the user whether or not the sentence is spelled correctly, i.e. every word is known in the dictionary.
The spell checker is available on my GitHub. Take a moment to study the Java version, we’ll discuss the Kotlin version next.
I’ve been exploring Kotlin recently. Kotlin is a new statically typed JVM language and was announced about half a year ago. This month JetBrains released its first milestone candidate which I decided to have a closer look at.
First of Kotlin is still in its early stages. A lot of things work pretty well (I’m especially impressed by the IDE support) but there are still numerous issues. I’ve hit a couple of bugs so far.
