Answer 1

In your client, when you look up the bean, the JNDI name should be "MyTrader",
not statelessSession.Client
Look at client.java in /examples/ejb/basic/statelessSession example,
In weblogic-ejb-jar.xml the jndi name is specified as follows:
<jndi-name>statelessSession.TraderHome</jndi-name>
and in the client program we look up the bean as follows:
JNDI_NAME=statelessSession.TraderHome
Object home = ctx.lookup(JNDI_NAME);
Make sure you are doing the same.
