Problems when process mail

[evidal]

Hi,

I have developped a Mail Listener that process the MailBody.
When i try to read the content of the mail body doing that

MailBody body = smtpMessage.getMailBody();
ByteArrayOutputStream out = new ByteArrayOutputStream();
body.write(out);
byte[] buffer = out.toByteArray();
String message = new String(buffer) ;

or that

MailBody body = smtpMessage.getMailBody();
int sizeInBytes = body.getSize();
InputStream is = body.getInputStream();
byte buffer[] = new byte[sizeInBytes];
int offset = 0;
for(int numRead = 0;offset < buffer.length && (numRead = is.read(buffer, offset, buffer.length - offset)) >= 0;offset += numRead);
String message = new String(buffer) ;

I've got a strange Exception :
java.util.zip.ZipException: unknown compression method

This is the complete stack for the fisrt code part :

Is something i doing wrong when i process the mail ?
Please help...

[acoliver]

I'll give this a try. This is with 1.0M4 correct?

[evidal]

Yes it's a 1.0M4.

[evidal]

If I set "useStore" to false in the MailBodyManager (in order to use the SimpleMailBody instead of StoredMailBody), it works.

[acoliver]

Odd. What DB is this?

[acoliver]

while that looks like a bug...try this:

MailBody retval = mgr.createMailBody(MailBody.STORED_TYPE, null,
message.getStoreId());

I wonder if there is a problem with one of the stores not putting all of the bytes together (paged store?). I should have a chance to try this soon.

[mikezzz]

MailBody body = smtpMessage.getMailBody();
ByteArrayOutputStream out = new ByteArrayOutputStream();
body.write(out);
byte[] buffer = out.toByteArray();
String message = new String(buffer) ;

Please note this is a really bad idea for a general mail server. You are loading the entire mail body into memory. We have taken great pains to ensure that this never happens with JBMS. I recommend alway handling the body of a message using a stream or a reader.

If you are using JBMS as a server where you have a fixed maximum size for you messages, then this is ok.

Mike.

[evidal]

We use JBMS as SMTP Listener, messages are SMS so their size are implicitly limited.

[acoliver]

In that event you're probably better off not using streams. You might want to explicitly limit the size in the config though. Otherwise one day some bored student will show you how he can OOME your show with his phone and a back massager :-)

[acoliver]

(I'll still dink with mail listeners and figure out what is going on but shift this slightly lower on my stack)
