Javamail application throws java.lang.OutOfMemoryError

Question

Hi,
ive made and javamail application, whenever i attach an attachment of around 600 kb or more the weblogic server throws an java.lang.OutOfMemoryError . Shouldnt the server be able to handle attachments of around 600 kb-2 mb ?
I'm using bea weblogic server 6.1 patch 4 with jdk 1.3.1 . Someone got a clue?, plz help, thanx.
here is a part of the code:
ByteArrayOutputStream buffer =
new ByteArrayOutputStream();
String name = null,
value = null,
filename = null,
contentType = null;
Dictionary fields = new Hashtable();
int i = in.readLine(bytes, 0, 512);
String st = null;
while ( -1 != i) {
st = new String(bytes, 0, i);
//memoryerror is thrown here after looping a while
if (st.startsWith(boundary)) {
state = 0;
if (null != name) {
if (value != null) {
fields.put(name,
value.substring(0,
// -2 to remove CR/LF
value.length() - 2));
else if (buffer.size() > 2) {
InternetHeaders headers =
new InternetHeaders();
MimeBodyPart bodyPart =
new MimeBodyPart();
DataSource ds =
new ByteArrayDataSource(
buffer.toByteArray(),
contentType, filename);
bodyPart.setDataHandler(
new DataHandler(ds));
bodyPart.setDisposition(
"attachment; filename=\"" +
filename + "\"");
bodyPart.setFileName(filename);

Hi Dan,
of course I can increase JVM memory, but that is not a right solution to hold whole network model in memory. You wrote that Release 2 brings some better approach that does not require loading of whole network into RAM. What I need to test it? I've 10.2 already installed. Do I need also new SDOAPI jars? If yes, where can be downloaded?
Thanks
