Attachment problem with Squid proxy

[Christian Gründemann <ch...@gruendemann.com>]

Hello!

I know this is not the correct mailinglist for my problem, but maybe someone
of you can give me a hint to. I haven't found a  solution for quite a while.
Thanks for your cooperation.

I have found a strange behaviour when I am using the jaxm api.
As long as I am sending pure xml data everything works fine. When I try to
add jpg pictures even this works, but if I use a squid proxy I get a strange
javax.internet.mail.ParseException which is shown at the end of the mail. I
have no idea why this happens, because without the squid proxy the jpg
picture is sent correctly.

If someone of you have any idea I would really appriciate your help, because
i ran out of ideas to solve that issue.
For more information I show you now some code fragments.

I am adding the picture like that
****************
data2 = new FileInputStream(new File("c:\picture.jpg"));
DataHandler dh = new DataHandler(new BinaryDataSource(data2));
AttachmentPart attachment2 = message.createAttachmentPart(dh);
attachment2.setContentType("image/jpeg");
attachment2.setContentId("some id");
message.addAttachmentPart(attachment2);

****************
the datahandler is like this
***********************

public class BinaryDataSource implements DataSource
{
private InputStream _is;

public BinaryDataSource(InputStream is)
{
 _is = is;
}
public String getContentType()
{
 return   "application/binary";
}
public InputStream getInputStream() throws IOException
{
 return _is;
}
public String getName()
{
 return "some file";
}
public OutputStream getOutputStream() throws IOException
{
 throw new IOException("Cannot write to this file");
}
an so on...

I sniffed the soap data via axis tcpmon and the only difference is
in the HTTP header, which is normal when using a squid proxy, i guess.

** Sniffed soap data.
