variable contains the hostname and port number of the
Network Server.
Original definitions
String driver = "org.apache.derby.jdbc.EmbeddedDriver";
String dbName="jdbcDemoDB";
String connectionURL = "jdbc:derby:" + dbName +
";create=true";

String driver = "org.apache.derby.jdbc.ClientDriver";
...
String connectionURL = "jdbc:derby://localhost:1527/" +
dbName + ";create=true";
f. Compile the application.
javac WwdClient.java
A command prompt appears if the compilation is successful. The binary
file
WwdClient.class
is created. If an error message appears, modify
the line indicated so that it is identical to the example. (As noted above,
you can compare the contents of your
WwdClient.java
against the
WwdClientExample.java
program provided in the
workingwithderby
directory to verify that your editing was performed successfully.)
