  1. This could be a reason of the locale of the machine not picked by Birt Engine
  2. To avoid the issues, please open this file

<JazzSM_HOME>\reporting\lib\birt-runtime-2_2_2\ReportEngine\configuration\config.ini

The contents of the file looks like below

#Product Runtime Configuration File

eclipse.product=org.eclipse.birt.report.engine.ReportEngineSDK

osgi.bundles=org.eclipse.equinox.common@2:start, org.eclipse.update.configurator@start, org.eclipse.birt.core@start

osgi.framework.extensions=org.eclipse.birt.api

osgi.bundles.defaultStartLevel=4

  1. Please add the following one more property to that file

osgi.nl=en

  1. After adding the the above property, the file looks like following
