The excellent Mr. Haki blog

My morning routine has changed recently. I check out Mr. Haki, fire up the Groovy console and run the latest example.

I have been seriously impressed with the work Mr. Haki is doing.

Even if nobody reads this post, I want to at least help his search rankings!

jRecruiter presentation at AJUG

Gunnar Hillert gave an excellent presentation on his jRecruiter project at AJUG last night.

I will soon be downloading jRecruiter to check it out in more depth. Gunnar mentioned that the Maven build is a little wonky at the moment. He said he would fix it in the next week or two.

He has a lot of really cool stuff in the app:

• Struts 2.1, which I have not used. I spent years using the Struts 1.* releases, but have been in the JSF camp for a while now.
• Twitter integration, which I've wanting to check out.
• GZip and minification.

Check out the project or his blog for a complete list.

"The processing instruction target matching "[xX][mM][lL]" is not allowed."

I often put the Xml I use for test cases inside of Groovy classes. This allows me to make use of multiline Strings.

String inputXml = '''
<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<records>
<record>
    <recordid>833432</recordid>
    <name>Lorem ipsum dolor</name>
    <parentid>0</parentid>

I ran into this error today :

"The processing instruction target matching "[xX][mM][lL]" is not allowed."

I'm surprised I hadn't run into it before. The problem was that I had white space before the xml prolog.

There are two easy solutions :

1. Remove the whitespace.
2. Call "trim()" on the String.

Whitespace removed :

String inputXml = '''<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<records>
 <record>
     <recordid>833432</recordid>
     <name>Lorem ipsum dolor</name>
     <parentid>0</parentid>

trim() called :

String inputXml = '''
