public class Rmic
extends MatchingTask

Runs the rmic compiler against classes.

Rmic can be run on a single class (as specified with the classname attribute) or a number of classes at once (all classes below base that are neither _Stub nor _Skel classes). If you want to rmic a single class and this class is a class nested into another class, you have to specify the classname in the form Outer$$Inner instead of Outer.Inner.

It is possible to refine the set of files that are being rmiced. This can be done with the includes, includesfile, excludes, excludesfile and defaultexcludes attributes. With the includes or includesfile attribute you specify the files you want to have included by using patterns. The exclude or excludesfile attribute is used to specify the files you want to have excluded. This is also done with patterns. And finally with the defaultexcludes attribute, you can specify whether you want to use default exclusions or not. See the section on directory based tasks, on how the inclusion/exclusion of files works, and how to write patterns.

This task forms an implicit FileSet and supports all attributes of <fileset> (dir becomes base) as well as the nested <include>, <exclude> and <patternset> elements.

It is possible to use different compilers. This can be selected with the "build.rmic" property or the compiler attribute. There are three choices:

• sun (the standard compiler of the JDK)
• kaffe (the standard compiler of Kaffe)
• weblogic

The miniRMI project contains a compiler implementation for this task as well, please consult miniRMI's documentation to learn how to use it.

Since:

Ant 1.1
