Get dynamic filename in a Java Mapping (NOT UDF)

Question

Hi,
we are using a Java Mapping step in XI (not UDF). We need to have access to the filename. In the File Adapter we set the message attributes and can see the filename value in the SXMB_MONI.
We use the following code fragment to have access to the filename:
Container container = new Context(new FunctionWrapper(0));
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String sourceFileName = conf.get(key);
This doesn't work. We think the declaration of the container class is wrong. Does anybody have some information about using the dynamic attributes in Java Mappings?
Thanks in advance
Michael

import com.sap.aii.mapping.api.*;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.HashMap;
import java.util.Map;
public class JavaProgram
    implements StreamTransformation
    public JavaProgram()
    public void setParameter(Map map)
        param = map;
        if(param == null)
            param = new HashMap();
    public void execute(InputStream inputstream, OutputStream outputstream)
        try
            DynamicConfiguration dynamicconfiguration = (DynamicConfiguration)param.get("DynamicConfiguration");
            DynamicConfigurationKey dynamicconfigurationkey = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "FileName");
            String s = dynamicconfiguration.get(dynamicconfigurationkey);
         //Your logic
        catch(Throwable throwable)
            throwable.printStackTrace();
    private Map param;
