  • EJB echoService Example Problems


    I am trying to deploy the echoService (Pro Spring) example in my Jboss-4.0.2. This is my first time with Spring and EJBs. When I try to use the client (the servlet that obtains de bean) I am getting the followings errors:

    13:54:23,196 INFO [DefaultListableBeanFactory] Creating shared instance of singleton bean 'echoService'
    13:54:23,278 INFO [LocalStatelessSessionProxyFactoryBean] Located object with JNDI name [java:comp/env/ejb/echoService]: value=[ejb/echoServiceHome]
    13:54:23,382 INFO [CollectionFactory] Using JDK 1.4 collections
