@mdahlman It worked, thanks. Which are the minimum libraries to make a report in Java?

@mdahlman I don't know if it is useful for me, I'm not so expert. I put all libraries in my project. Anyway, why that error inside the library? What is Hadoop Hive?

@mdahlman Sorry, question edited.

Hello, I got an error launching my jasper app from Java. Everithing works fine, but I have this stackstrace in my console: Error instantiating extensions registry for queryexecuters.hive from jar:file:/C:/Users/Username/workspace/.metadata/.plugins/org.eclipse.wst.server.‌ ​ core/tmp3/wtpwebapps/MyAPP/WEB-INF/lib/js-hive-datasource-1.1.jar!/jasperrepo‌ ​rts_extension.properties Why it can't find jasperreports_extension.properties into the jar? Is there some bug inside the library?

Any help?

When I call in my code: JasperDesign jasperDesign = JRXmlLoader.load(reportTemplate); [/code]it print to console an error and then throws me an exception: ERROR extensions.DefaultExtensionsRegistry: Error instantiating extensions registry for queryexecuters.hive from jar:file:/C:/Users/GDantimi/workspace/ProvaJasper/lib/js-hive-datasource-1.1.jar!/jasperreports_extension.properties net.sf.jasperreports.engine.JRRuntimeException: Could not load class com.jaspersoft.hadoop.hive.HiveQueryExecuterExtensionsRegistryFactory at net.sf.jasperreports.engine.util.ClassUtils.instantiateClass(ClassUtils.java:63) I searched for that library but I haven't found anything.
