21 :     <br>The batch compiler class is located in the internal classes of the
22 :     JDT/Core plugin. So it is in the <i>jdtcore.jar</i> file in the directory
23 :     <i>plugins/org.eclipse.jdt.core</i>.
24 :     The name of the class is <i>org.eclipse.jdt.internal.compiler.batch.Main</i>.&nbsp;</td>

31 :     <ul>
32 :     <li>
33 :     Using the main method.</li>
34 :    
35 :     <blockquote>Using the main method. The Main class has a main method. This
36 :     is the classical way to invoke the batch compiler on a command-line.
37 :     <ul>
38 :     <li>
39 :     For example on a command-line:</li>
40 :    
41 :     <br><font color="#3366FF">java -classpath jdtcore.jar org.eclipse.jdt.internal.compiler.batch.Main
42 :     -classpath rt.jar A.java</font>
43 :     <li>
44 :     For example in a java source:</li>
45 :    
46 :     <br><font color="#3366FF">org.eclipse.jdt.internal.compiler.batch.Main.main(new
47 :     String[] {"-classpath", "rt.jar", "A.java"});</font></ul>
48 :     </blockquote>
49 :    
50 :     <li>
51 :     Using the static compile(String) method.</li>
52 :    
53 :     <blockquote>The compile(String) method is a convenient method to invoke
54 :     the batch compiler in a java application.
55 :     <br>Instead of:
56 :     <ul>
57 :     <li>
58 :     <font color="#3366FF">org.eclipse.jdt.internal.compiler.batch.Main.main(new
59 :     String[] {"-classpath", "rt.jar", "A.java"});</font></li>
60 :    
61 :     <li>
62 :     you can simply write: <font color="#3366FF">org.eclipse.jdt.internal.compiler.batch.Main.compile("-classpath
63 :     rt.jar A.java");</font></li>
64 :     </ul>
