My configuration: - XWiki 2.7 - Tomcat 6.0.28 - MySql  5.1.49 - Java SUN 6.22 - Ubuntu 10.10 The flowing works well {{groovy jars="attach:plantuml.jar"}} def version = Class.forName("net.sourceforge.plantuml.version.Version", false, this.getClass().getClassLoader()).getConstructor().newInstance() print version.version() {{/groovy}} But this one fails {{groovy jars="attach:plantuml.jar"}} import net.sourceforge.plantuml {{/groovy}} org.xwiki.rendering.macro.MacroExecutionException: Failed to evaluate Script Macro for content [import
