Hello,
That's basically what I tried actually, but I am facing an issue where the line
jpgFile = new java.io.File(source);
does not reference the file I want because:
1. I miss the source folder. As an example task:
<copy todir="C:\A">
<fileset dir="C:\B" includes="*.JPG" />
<mapper... />
</copy>
Here, the variable "source" would be something matched by *.JPG. It
does not include the folder C:\B.
2. There might be previous mappers that changed the filename.
My question was more to know if there was anyway to access the source
File object *directly* from a mapper.
Something like
public File getSourceFile();
would be perfect ;)
Thanks anyways.

As the manual sais about file mappers [1], you have to implement
org.apache.tools.ant.util.FileNameMapper [2]. Basically to setters for your own
parametrization and - most important - the map-method
/**
* Returns an array containing the target filename(s) for the
* given source file.
*
* <p>if the given rule doesn't apply to the source file,
* implementation must return null. SourceFileScanner will then

*
* @param sourceFileName the name of the source file relative to
* some given basedirectory.
* @return an array of strings if the ruld applies to the source file, or
* null if it does not.
*/
String[] mapFileName(String sourceFileName);
With Ant 1.7 you could also use a <scriptmapper>:
<scriptmapper language="javascript">
jpgFile = new java.io.File(source);
exifName = getNameByExifInfo( jpgFile ); // your work ;-)
self.addMappedName( exifName );
</scriptmapper>
