Listing C-2. A RowSetTest Class That Uses Classes from the javax.sql Package
// RowSetTest.java
package com.jdojo.profiles;
import java.sql.SQLException;
import javax.sql.rowset.JdbcRowSet;
import javax.sql.rowset.RowSetFactory;
import javax.sql.rowset.RowSetProvider;
public class RowSetTest {
public static void main(String[] args) {
try {
RowSetFactory rsFactory = RowSetProvider.newFactory();
JdbcRowSet jdbcRs = rsFactory.createJdbcRowSet();
// More code goes here
}
catch (SQLException e) {
e.printStackTrace();
}
}
}
The source code for the SwingTest class uses the javax.swing package that is part of the full JRE. If you try
compiling the class targeting the compact3 profile, it will generate compile-time errors because the javax.swing
package is available in the full JRE, not in the compact3 profile, as listed in Table C-2 .
javac -profile compact3 SwingTest.java
SwingTest.java:4: error: JFrame is not available in profile 'compact3'
import javax.swing.JFrame;
^
SwingTest.java:8: error: JFrame is not available in profile 'compact3'
JFrame frame = new JFrame("Compact Profiles");
^
SwingTest.java:8: error: JFrame is not available in profile 'compact3'
JFrame frame = new JFrame("Compact Profiles");
^
3 errors
The following command using the full JRE compiles the SwingTest.java fine:
javac SwingTest.java
The following command will compile the RowSetTest class file fine as the command uses compact3 as the
-profile option that matches the packages used inside the RowSetTest class:
javac -profile compact3 RowSetTest.java
