OutOfMemory in org.apache.axis.utils.ByteArrayOutputStream

[Chapoor Chapoor <ch...@gmail.com>]

Hi after tracing the Axis source code I can tell this:

When the AxisClient call the .invoke method I receive an OutOfMemory
exception (while the message I try to send is big one).

AxisClient.invoke() -> SimpleChain -> HTTPSender -> Message ->
SOAPPart -> ByteArray -> ByteArrayOutputStream.

The ByteArray's makeInputStream method  calls the toByteArray in
ByteArrayOutputStream:

    public synchronized byte toByteArray()[] {
        int remaining = count;
        int pos = 0;
        byte newbuf[] = new byte[count]; <--- the problem!
        for (int i = 0; i < buffers.size(); i++) {
            byte[] buf = getBuffer(i);
            int c = Math.min(buf.length, remaining);
            System.arraycopy(buf, 0, newbuf, pos, c);
            pos += c;
            remaining -= c;
            if (remaining == 0) {
                break;
            }
        }
        return newbuf;
    }


The error raise when the byte newbuf[] = new byte[count]; is been
called. While the count is high?

I ve tried to increase the memory given to my application but the
problem is still there.

Please give me a work around for this!

Thanks.
