In "Enterprise JavaBeans, 2nd Edition", Chapter 4 Section 2-10, the last paragraph

Once a JNDI connection is established and a context
is obtained from the getIntialContext() method, the
context can be used to look up the EJB home of the Cabin
bean:

I think "getIntialContext() method" should be "getIintialContext() method"
(letter "i" is forgotten).

I noticed an error on your Enterprise Java Beans. Under the following topic, I
omitted part of the chapter and give you some guide, please read on.

6.2. Bean-Managed Persistence

6.2.10. ejbFind( ) Methods
EJB 1.0 empty sets and exceptions

finally {

try {

if (result != null) result.close();

if (ps != null) ps.close();

if (con!= null) con.close();

} catch(SQLException se){

se.printStackTrace();

}

}

}

The mandatory findByPrimaryKey() method uses the primary key to locate the
corresponding database record. Once it has verified that the record exists,
it simply returns the primary key to the container, which then uses the key
to activate a new instance and associate it with that primary key at the
appropriate time. *****If the there is no record associated with the
primary key, the method throws a ObjectNotFoundException. ***** read this
sentence /// ;~ )

The ejbFindByCapacity() method returns an enumeration of primary keys that
match the criteria passed into the method. Again, we construct a prepared
statement that we use to execute our SQL query. This time, however, we
expect multiple results so we use the java.sql.ResultSet to iterate through
the results, creating a vector of primary keys for each SHIP_ID returned.

2nd paragraph; The code snippet reads

con.setTransactionIsolation(TRANSACTION_READ_COMMITTED)

It should read:

con.setTransactionIsolation(Connection.TRANSACTION_READ_COMMITTED)

since the constant is static.

4th paragraph

At the beginning of the 4th paragraph, in the sentence "To store an object ...
and the setObject() method..." the article "the" is written using the wrong
font face (Letter Gothic instead of the normal font).

2nd paragraph

In the code snippet, the line

local.bind(server,"Server");

should be:

local.bind("Server",server);

since the signature of the method "bind" takes first the name of the object and
then the object.
