Thx for your help ! application.xml : <?xml version="1.0" encoding="UTF-8"?> <application id="Application_ID" version="1.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application_1_4.xsd"> <display-name>FINDOK_Trip</display-name> FINDOK_TripJCA.rar FINDOK_TripTreeCache.jar antlr.jar commons-beanutils.jar commons-collections-3.1.jar commons-configuration-1.1.jar commons-digester.jar commons-fileupload.jar commons-lang-2.0.jar commons-logging.jar commons-validator.jar jakarta-oro.jar log4j-1.2.8.jar struts.jar tripjtk.jar triputil.jar jboss-cache.jar jgroups.jar xercesImpl.jar FINDOK_Util.jar FINDOK_EJB_Trip_Config.jar <!-- Findok_User.jar --> <!-- FINDOK_UserDummy.jar --> FindokController.jar jar -tf FINDOK_EJB_Trip.ear : Doesnt work...but i think you mean what the .ear contains ? FINDOK_EJB_Trip_Config.jar FINDOK_TripTreeCache.jar FINDOK_Util.jar FindokController.jar jboss-serialization.jar Manifest.mf Findok_TripJCA.rar application.xml I know that some jars are missing here...for example the antlr.jar And thats the reason for the error. But i would like to know why the Eclipse SDK 3.2 do not put the jar's in the EAR. What could be the reason why the EARDeployer cant recognize some jar's as "Extracted deployable content" ?
