Servicemix: Could not parse settings maven_path/settings.xml under Windows XP

Today I encountered problem with servicemix

Could not parse settings [file:/C:/Documents and Settings/Bartek/.m2/settings.xml]

A quick look at karaf.log revealed the problem

Caused by: com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: Invalid byte 2 of 4-byte UTF-8 sequence.

So the problem is with BOM (byte order mark) in settings.xml file. Many Windows editors add it at start of an utf encoded files. You should save settings.xml as ordinary utf8 file without BOM.

Problem solved.

New HTTP Logger Grails plugin

I've wrote a new Grails plugin - httplogger. It logs:

  • request information (url, headers, cookies, method, body),
  • grails dispatch information (controller, action, parameters),
  • response information (elapsed time and body).

It is mostly useful for logging your REST traffic. Full HTTP web pages can be huge to log and generally waste your space. I suggest to map all of your REST controllers with the same path in UrlMappings, e.g. /rest/ and configure this plugin with this path.

Here is some simple output just to give you a taste of it.
