1) As I see in the source code of ManagedMemoryDataSource, it does not use
at all provided InputStream is readall parameter == false. Is it bug?
2) I really does not understand what means maxCached parameter :(
3) I try to use my own DataSource for sending binary data as attachment.
I have wrote such class:

package samples.test4;
import javax.activation.*;
import java.io.*;
public class BinDataSource implements DataSource
{
private String _contentType;
private String _name;
private byte _data[];
private InputStream _is;
private OutputStream _os;
public BinDataSource(String contentType, String name, byte[] data)
{
_contentType = contentType;
_name = name;
_data = data;
_is= new ByteArrayInputStream(_data);
_os = new ByteArrayOutputStream();
}
public InputStream getInputStream() throws IOException {return _is;}
public OutputStream getOutputStream() throws IOException {return
_os;}
public String getContentType() {return _contentType;}
public String getName() {return _name;}
}

But if I use it for constructing DataHandler and returning this DataHandler
from service method, I receive exception :
What I am doing wrong?
