Preverifying Class Files

The next step is to preverify the class files. The bin directory of the Java ME Platform SDK includes the preverify utility. The syntax for the preverify command is as follows:

preverify files | directories

Some of the options are as follows:

-classpath classpath
Specify the directories or JAR files (given as a semicolon-delimited list) from which classes are loaded.
-d output-directory
Specify the target directory for the output classes. This directory must exist before preverifying. If this option is not used, the preverifier places the classes in a directory called output.

Following the example for compiling, use the following command to verify the compiled class files. As before, newlines are added for clarity.

preverify   -classpath ..\..\lib\cldcapi10.jar;..\..\lib\midpapi20.jar   -d classes   tmpclasses

As a result of this command, preverified class files are placed in the classes directory. If your application uses WMA, MMAPI, or other versions of CLDC or MIDP, be sure to include the relevant .jar files in the classpath.
