In case that you specify interface type for entity bean in ejb-jar.xml that does not correspond with definition in the class of the bean then just Null Pointer exception is shown without any other info what's happening.

I mean when you define bean through interface as remote and the ejb-jar.xml describes bean interfaces as local
{code}
public interface SomeBean extends EJBObject {
...
}
public interface SomeBeanHome extends EJBHome {
...
}
{code}
and the ejb-jar.xml looks like
{code}
<ejb-jar xmlns="http://java.sun.com/xml/ns/javaee"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd" version="3.1">
  <enterprise-beans>
    <entity>
      <ejb-name>SomeBean</ejb-name>
      <local-home>package.SomeBeanHome</local-home>
      <local>package.SomeBean</local>
      <ejb-class>package.SomeBeanBean</ejb-class>
      <persistence-type>Bean</persistence-type>
      <prim-key-class>java.lang.Integer</prim-key-class>
      <reentrant>true</reentrant>
    </entity>
  </enterprise-beans>
</ejb-jar>
{code}

then NullPointerException is thrown
{code}
