not the "cabin" directory.

"jar cf cabin.jar"

NOW READS:
"jar cf travelagent.jar", in both command lines.

The code of setting jndiContext:
javax.naming.Context ctx = new javax.naming.InitialContext()

NOW READS:
javax.naming.Context ctx = getInitialContext();

The Client.java-program contains a typo when creating the primary key.
The sentence
(java-code) should be changed from
"Integer primaryKey = new Integer(args[i]);" to
"Integer primaryKey = new Integer(i);" in both for-loops.

The java-code would try to insert a record in the DB with a key equal to
the argument
passed from the command-line, which will fail because the argument
passed will be a
String even if the letter "1" was passed.

AUTHOR: How to fix this:

The following line occurs twice in the code listin on page 166.

"Integer primaryKey =new Integer(args [ i ]);"

CHANGE IT TO (replace args[ i ] with i):

"Integer primaryKey =new Integer( i );"
