EJB home [null] has no no-arg create() method. It's there
I recieve this error when binding to a remote stateless EJB.
As you can see, the BeanDelegate class locates the Remote Bean via JNDI. The BeanDelegate class extends SimpleRemoteStatelessSessionProxyFactoryBean, and simply adds the ability to specify a java.namming.provider.url so that the administrator can change the xml file as the web client is moved from environment to another environment. This worked on Friday, I came in on Monday, and somehow this has become broken. I'm unable to track down the cause and any help would be greatly appreciated. Below are my client classes.Code:[11/1/04 13:25:44:114 EST] e910e91 DefaultListab I org.springframework.beans.factory.support.DefaultListableBeanFactory Pre-instantiating singletons in factory [org.springframework.beans.factory.support.DefaultListableBeanFactory defining beans [UserManager];
