Here's our guide to tame JasperReports in OSGi : 10JasperReports10.1Core in OSGiJasperReports core in OSGi/Karaf works quite well: You need to either: Import-Package all JasperReports packages (about 50!) DynamicImport-Package: net.sf.jasperreports.* (I prefer this) Require-Bundle: (not good!) Also import the packages that you use e.g. joda time, joda money Add mvn:commons-digester/commons-digester/2.1 (already OSGi bundle). Add wrap:mvn:com.lowagie/itext/2.1.7$Export-Package=*;version="2.1.7" This works well for id.co.bippo.salesorder.rs: org.apache.felix maven-bundle-plugin true net.sf.jasperreports.* org.joda.time, * However, there are several common complications: Extensions Groovy 10.2Extensions in OSGiJasperReports extensions must be installed as OSGi fragment and before the JasperReports library bundle.
