Here is the constructor:
---------
/**
* Create a datasource from an input stream.
*
* @param is InputStream
* @param type Content-Type
*/
public ByteArrayDataSource(InputStream is, String type)
throws IOException {
this.type = type;
ByteArrayOutputStream os = new ByteArrayOutputStream();
byte buf[] = new byte[4096];
int len;
while (true){
len = is.read(buf);
if (len < 0)
break;
os.write(buf, 0, len);
}
data = os.toByteArray();
}
---------
As you see, the data is read into memory. It would be an easy thing
to do to implement your own DataSource. Simply get the SOAP-Source
and look into "org.apache.soap.util.mime.ByteArrayDataSource".
But maybe there is a better datasource in JavaMail?!
If you wrote your own DataSource, that reads from an InputStream,
tell me! I think we could also need something like that.
