The key to avoiding the use of a disk file is to use a
"ByteArrayDataSource" in the DataHandler for the attachment. A class
like this wasn't provided out of the box, so you have to provide it.
I'll include the one I have. It isn't optimized, in case that's an
issue for you.
------------------
/**
* This class is used along with the DataHandler to attach a byte
array as
* an email attachment.
*/
public static class ByteArrayDataSource implements DataSource
{
private InputStream inputStream;
private byte[] data;
private boolean dataLoaded = false;
private String contentType;
private String name;
public ByteArrayDataSource(InputStream inputStream,
String contentType,
String name)
{
setContentType(contentType);
setName(name);
setInputStream(inputStream);
}
public ByteArrayDataSource(byte[] data,
String contentType,
String name)
{
setContentType(contentType);
setName(name);
setData(data);
}
public ByteArrayDataSource(String data,
String contentType,
String name)
{
setContentType(contentType);
setName(name);
setData(data.getBytes());
}
void loadData()
throws IOException
{
int available = 0;
while ((available = inputStream.available()) > 0)
{
byte[] newdata = new byte[available];
if (data == null)
data = newdata;
else
{
byte[] olddata = data;
data = new byte[olddata.length + newdata.length];
System.arraycopy(olddata, 0, data, 0,
olddata.length);
System.arraycopy(newdata, 0, data, olddata.length,
newdata.length);
}
}
data = new byte[inputStream.available()];
int readBytes = inputStream.read(data);
setData(data);
}
public void setInputStream(InputStream inputStream)
{ this.inputStream = inputStream; }
public void setContentType(String contentType)
{ this.contentType = contentType; }
public void setName(String name)
{ this.name = name; }
public void setData(byte[] data)
{
this.data = data;
dataLoaded = true;
}
public InputStream getInputStream()
throws IOException
{
if (!dataLoaded)
loadData();
return (new ByteArrayInputStream(data));
}
public OutputStream getOutputStream()
throws IOException
{
throw new
UnsupportedOperationException("This is a read-only
DataSource");
}
public String getContentType() { return (contentType); }
public String getName() { return (name); }
}
