Hello Richard, Thank you so much for your answer. Yes you were right I forgot to import the org.osgi.framework package. It was the right solution.
But now I have a new problem of java.lang.NoClassDefFoundError: org/saxpath/SAXPathException wich I do not understand because the Jar is embedded in the Bundle and is in the class Path. Thanks again, Regards, Renaud *The listing of my bundle:* META-INF\MANIFEST.MF META-INF META-INF\maven META-INF\maven\fr.numvision META-INF\maven\fr.numvision\kernel META-INF\maven\fr.numvision\kernel\pom.properties META-INF\maven\fr.numvision\kernel\pom.xml cron4j-2.1.1.jar fr fr\numvision fr\numvision\kernel fr\numvision\kernel\CronRunner$CronRunnerTask.class fr\numvision\kernel\CronRunner.class fr\numvision\kernel\IterativeRunner.class fr\numvision\kernel\Logger$1.class fr\numvision\kernel\Logger$LoggingLevel.class fr\numvision\kernel\Logger.class fr\numvision\kernel\ServiceRunnable.class fr\numvision\kernel\box fr\numvision\kernel\box\ConfigDAO.class fr\numvision\kernel\box\KernelActivator.class fr\numvision\kernel\sat fr\numvision\kernel\sat\ConfigDAO.class fr\numvision\kernel\sat\Host$HostType.class fr\numvision\kernel\sat\Host.class fr\numvision\kernel\sat\Informer.class fr\numvision\kernel\sat\Installer$IdFactory.class fr\numvision\kernel\sat\Installer.class fr\numvision\kernel\sat\KernelActivator.class fr\numvision\kernel\supervision fr\numvision\kernel\supervision\ConfigDAO.class fr\numvision\networkdiscovery fr\numvision\networkdiscovery\box fr\numvision\networkdiscovery\box\Broadcaster.class fr\numvision\networkdiscovery\sat fr\numvision\networkdiscovery\sat\BoxListener.class jaxen-core-1.0-FCS.jar jaxen-jdom-1.0-FCS.jar jdom-1.1.jar log4j-1.2.13.jar saxpath-1.0-FCS.jar *The content of the MANIFEST:* Manifest-Version: 1.0 Export-Package: fr.numvision.networkdiscovery.sat;uses:="fr.numvision. common.xml,fr.numvision.kernel,fr.numvision.common,fr.numvision.kerne l.sat",fr.numvision.kernel,fr.numvision.kernel.box;uses:="fr.numvisio n.common.xml,fr.numvision.kernel,fr.numvision.networkdiscovery.box,or g.osgi.framework",fr.numvision.networkdiscovery.box;uses:="fr.numvisi on.kernel,fr.numvision.kernel.box",fr.numvision.kernel.supervision,fr .numvision.kernel.sat;uses:="fr.numvision.common.xml,fr.numvision.com mon,fr.numvision.common.ssh,fr.numvision.common.windows,fr.numvision. kernel,fr.numvision.networkdiscovery.sat,org.osgi.framework" Private-Package: org.apache.log4j.net,org.apache.log4j.lf5.util,org.ja xen.pattern,org.apache.log4j.lf5.viewer,org.apache.log4j.jmx,org.apac he.log4j.jdbc,org.apache.log4j.config,org.apache.log4j.helpers,org.ap ache.log4j,org.jaxen.jdom,org.saxpath.conformance,org.apache.log4j.or .jms,org.apache.log4j.lf5.config,org.apache.log4j.spi,org.apache.log4 j.nt,org.saxpath,org.jdom.xpath,com.werken.saxpath,org.apache.log4j.l f5,org.apache.log4j.xml,org.apache.log4j.chainsaw,org.jaxen,org.jdom, org.jdom.transform,org.jaxen.expr,org.jaxen.expr.iter,org.apache.log4 j.lf5.viewer.images,it.sauronsoftware.cron4j,org.jdom.output,org.jdom .input,org.jdom.filter,org.apache.log4j.or.sax,.,org.apache.log4j.lf5 .viewer.categoryexplorer,org.jaxen.util,org.jaxen.function.ext,org.ap ache.log4j.or,org.saxpath.helpers,org.jaxen.function,org.apache.log4j .varia,org.jdom.adapters,org.apache.log4j.lf5.viewer.configure Bundle-ClassPath: .,cron4j-2.1.1.jar,saxpath-1.0-FCS.jar,jaxen-jdom-1. 0-FCS.jar,jdom-1.1.jar,jaxen-core-1.0-FCS.jar,log4j-1.2.13.jar Built-By: renaud Tool: Bnd-0.0.311 Bundle-Name: kernel Created-By: Apache Maven Bundle Plugin Build-Jdk: 1.6.0_17 Bundle-Version: 2.0 Bnd-LastModified: 1263408980776 Bundle-ManifestVersion: 2 Bundle-Activator: fr.numvision.kernel.sat.KernelActivator Embed-Dependency: *;scope=compile|runtime Import-Package: com.sun.jdmk.comm;resolution:=optional,fr.numvision.co mmon;resolution:=optional,fr.numvision.common.ssh;resolution:=optiona l,fr.numvision.common.windows;resolution:=optional,fr.numvision.commo n.xml;resolution:=optional,fr.numvision.kernel;resolution:=optional,f r.numvision.kernel.box;resolution:=optional,fr.numvision.kernel.sat;r esolution:=optional,fr.numvision.kernel.supervision;resolution:=optio nal,fr.numvision.networkdiscovery.box;resolution:=optional,fr.numvisi on.networkdiscovery.sat;resolution:=optional,javax.jms;resolution:=op tional,javax.mail;resolution:=optional,javax.mail.internet;resolution :=optional,javax.management;resolution:=optional,javax.naming;resolut ion:=optional,javax.swing;resolution:=optional,javax.swing.border;res olution:=optional,javax.swing.event;resolution:=optional,javax.swing. table;resolution:=optional,javax.swing.text;resolution:=optional,java x.swing.tree;resolution:=optional,javax.xml.parsers;resolution:=optio nal,javax.xml.transform;resolution:=optional,javax.xml.transform.sax; resolution:=optional,javax.xml.transform.stream;resolution:=optional, oracle.xml.parser;resolution:=optional,oracle.xml.parser.v2;resolutio n:=optional,org.apache.xerces.dom;resolution:=optional,org.apache.xer ces.parsers;resolution:=optional,org.osgi.framework,org.w3c.dom;resol ution:=optional,org.xml.sax;resolution:=optional,org.xml.sax.ext;reso lution:=optional,org.xml.sax.helpers;resolution:=optional Bundle-SymbolicName: fr.numvision.kernel 2010/1/13 Richard S.
