[jbossws-users] [JBoss Web Services Users] - Soap Attachment causes OutOfMemoryError
Hello Everyone,
I am building a Web Services that will receive a file attachment in its message.
I used the DataHandler classe and the specified annotations (@XmlAttachmentRef) and it
worked prety fine.
The problem is that when the file to be transmited is really big (more than 100MB, for
example) the Client throws an
java.lang.OutOfMemoryError, and I belive it does that before even start sending the
message.
My Client code is:
| SignerService service = new SignerService();
| Signer signer = service.getSignerPort();
|
| BindingProvider bp = (BindingProvider)signer;
| Binding binding = bp.getBinding();
| ((SOAPBinding)binding).setMTOMEnabled(true);
|
| String path = "..."; //My file path
|
| MyDocument doc = new MyDocument();
| FileDataSource dataSource = new FileDataSource(path);
| doc.setDataHandler(new DataHandler(dataSource));
|
| signer.sendDoc(doc);
|
Where MyDocument is:
| @XmlAccessorType(XmlAccessType.FIELD)
| @XmlType(name = "myDocument", propOrder = {
| "dataHandler"
| })
| public class MyDocument {
|
| @XmlElement(type = String.class)
| @XmlAttachmentRef
| protected DataHandler dataHandler;
|
| public DataHandler getDataHandler() {
| return dataHandler;
| }
| public void setDataHandler(DataHandler value) {
| this.dataHandler = value;
| }
| }
|
The stack trace is:

Increasing the Java heap space of Client (to 256MB) does resolve the problem for that file
but if I try sending a bigger file
(500MB) the Error comes back. Since I can't limit a file size to my system, increasing
the heap space is only a workaround.
It seems that the whole file is being loaded into the memory heap and I though DataHandler
class and MTMO property were to address this memory problem, by using cache and flushing
routines.
Is there anyway to assure that my file will be sent regardless of its size?
Thank you very much
