Hi, in this case, your WAR has to contain the classes of the DAOs and of the EJB interfaces. Creating a so called "client JAR" file with those classes and placing it in WEB-INF\lib is the easiest approach. But the even easier way is to bundle JAR and WAR in an EAR file, as they seem to deployed to the same server. This way, adding the EJB jar to the "Classpath" attribute in Manifest.mf will solve all your problems ;-).
