RE: I/O Exception w/ file posting - 2nd try
Hi,
I don't know if you'll find this usefull since you don't want to write your
own, but implementing your own upload class is not that difficult, this
tutorial (see url below) (although oriented around javamail) shows you how
to do it and then you can tweak it to your liking:

Subject: I/O Exception w/ file posting - 2nd try
(warning long post follows)
UsingOrion 1.5.2.
I have a bunch of users doing some very high volume uploads of files ranging
anywhere from 1Mb to about 70Mb.
I am using Orion's FilePostParser class to parse the input stream and
collect files and other data.
Every so often (becoming regular now), I keep getting the following sets of
errors
com.evermind.server.http.HttpIOException: Read timed out
at com.evermind._crb.read(Unknown Source)
at com.evermind.io.FilePostParser._afc(Unknown Source)
at com.evermind.io.FilePostParser._ajc(Unknown Source)
at com.evermind.io.FilePostParser.init(Unknown Source)
com.evermind.server.http.HttpIOException: Connection reset by peer: JVM_recv
in socket input stream read
at com.evermind._crb.read(Unknown Source)
at com.evermind.io.FilePostParser._afc(Unknown Source)
at com.evermind.io.FilePostParser._ajc(Unknown Source)
at com.evermind.io.FilePostParser.init(Unknown Source)
.
java.lang.ArrayIndexOutOfBoundsException
at com.evermind.io.FilePostParser._hy(Unknown Source)
at com.evermind.io.FilePostParser._aec(Unknown Source)
at com.evermind.io.FilePostParser._aic(Unknown Source)
at com.evermind.io.FilePostParser._ahc(Unknown Source)
at com.evermind.io.FilePostParser.hasMoreElements(Unknown Source)
..
The users are sitting on a T1 and my server is at a managed hosting site
which has OCxx coming in. The servers themselves have 100MBs LAN
connnection to the switch. The server is on a 1.2GHz dual proc with 1GB Ram.
Have others seen such errors. Are there any caveats to using Orion's class.
I am using the orion class in the following manner:
Enumeration enumeration = new
FilePostParser(request.getInputStream(), request.getContentLength());
(This line alone may generate the 2 different flavors of
HttpIOException listed above)
...
while(enumeration.hasMoreElements()) {// another source of
error - mostly ArrayIndexOutOfBounds
{
Object element = enumeration.nextElement();
if ( element instanceof Map.Entry ) { // do something }
else if (element instanceof PostFileInputStream)
... // do a buffered read from stream using a buffer of
about 8K
int size = inStream.read(fileBytesArray,0,BUFFSIZE);
// -- another source of HttpIOException
}
}
}
What's really causing the errors? My understanding is that for the
enctype=multipart/form-data, its really a live input stream
which means that for a sufficiently large post not all data will arrive in
one chunk and the server will keep getting data from the browser until its
been sent. I don't believe bandwitdth is an issue.
Do I need to switch to the orielly version of parser classes. (I don't
really want to write my own)
I'd appreciate any pointers/comments
TIA

RE: arrg please help
Actually I worked that one out and got a new, better bug. This was happening because I didn't set exclusive-write-access to false in orion-ejb-jar.xml. Since I'm using cmp, I don't have any statements of my own. thanks, Bjarni -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of John Creaner Sent: 3. apríl 2002 11:50 To: Orion-Interest Subject: RE: arrg please help thats sounds like an sql issue, are you closing your statement before you get all the information in the resultset back??

It sounds like BMP and you are accidentally closing the connetion somewhere you are not supposed to inside the bean. What kind of database are you connecting to (i.e. MySQL, SQL Server, Oracle,etc...) I need a little more info here before I can try to help. :-) Later...
