Annotation processing using JDK 1.6 and Apache Ant

Question

Hello,
I am trying to run my annotation processor using ant.
I already built the processor, the javax.annotation.processor.Processor file is in the correct place with the correct content.
The jar with the processor is in the classpath (i can see it in ant -v), but it does not process my classes. in fact, i get the warning:
warning: Annotation processing without compilation requested but no processors were found.Do i have to specify -processor or -processorpath or can i just leave it to the default classpath scanning?
I think everything is in the correct place, because when i compile with maven instead of ant, specifying the processor, it runs nicely. My pom contains:
               <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-compiler-plugin</artifactId>
                    <configuration>
                         <source>1.6</source>
                         <target>1.6</target>
                         <compilerArguments>
                              <processor>br.com.sonner.infra.seguranca.SegurancaAnnotationProcessor</processor>
                         </compilerArguments>
                    </configuration>
               </plugin>i am using jdk 1.0.6_02 and ant 1.7.0.
Can anyone help me find out what am i doing wrong?

In addition to the class files of the process, to allow your processor to be found as a service, make sure you've also provided the needed META-INF data in the jar file. The general service file format is described in
http://java.sun.com/javase/6/docs/api/java/util/ServiceLoader.html
That said, I'd recommend setting an explicit processor path separate from your general classpath.
