I'm using Tomcat 7 and am learning JSP. I am trying to build a list of files in a directory with a specific extensions. I found this tutorial, and I have the following code:
package winning;
import java.io.File;
import java.io.FileFilter;
import java.util.List;
import java.util.ArrayList;
public class Winning {
public List<String> getNames(String directory, String extension){
final String ext = extension;
File f = null;
File[] names;
List<String> results = new ArrayList<String>();
f = new File(directory);
FileFilter filter = new FileFilter() {
@Override
public boolean accept(File pathname){
return true;
}
};
names = f.listFiles(filter);
for(File file : names){
results.add(file.getName());
}
return results;
}
}
The exception that Tomcat presents is NoClasDefFoundError, but it reports that a ClassNotFoundException is being thrown at the FileFilter filter = new FileFilter... line.
My code works perfectly fine if I get rid of that block, so I have:
...
f = new File(directory);
// used to be code here
names = f.listFiles(/*no more filter*/);
...
It looks to me like basically have the same code as the example, but it's not working. Is this tutorial just really out dated, or is there a way to use an anonymous class here?
