Hello
We are using ULC 6.0.5
Yes we are using the ULCFiletransfer Example from the communitiy.
We are using JNLP
In the code i found a part:
In the "handleStoreFile" method in the class UIFileUploader is the code i think
which is the problem.
....
bin = new
ByteArrayInputStream(uploadedBytes.toByteArray());
//
fileService.storeFile(clientFilePath, bin);
fileService.storeFile(clientFilePath, bin);
...
I think when i transfer a big file the uploadedBytes array is to big to store
it to the file.
But i have to user the method storeFile to store the file????

Hi Holger,
Which version of ULC are you using?
Are you using code from the community? Which version?
How have you deployed your ULC client? As an applet or jnlp?
Can you please send me the whole stack trace?
>From what I understand from the given information, FileUploadTaskList, with
30*1024 bytes per Task, will send the file from server to client in chunks of
30K bytes. However, the client keeps on accumulating these bytes and allocates
memory in chunks. Therefore, at some point of time it will need 46MB of memory.
So you need to increase the heap size of your JVM on each machine where the ULC
client is running (this may not be practical). So you need to modify
UIFileUpLoader to handle that. This source code is part of community and you
can change it as you wish.
Thanks and regards,
Janak

Subject: [ULC-developer] Problems with large files and ULCFileTransfer
Hi Community,
I'm trying to transfer a file to the client using ULCFileTransfer.
Are there any restrictions relating the file size?
When I try to transfer a file with a size of 46 MB, I get following Exception
on client side:
Thread[AWT-EventQueue-2,6,javawsApplicationThreadGroup]
com.ulcjava.base.client.UISession b got exception while processing
[java.lang.OutOfMemoryError: Java heap space] I'm initialising my
FileUploadTaskList with 30*1024 bytes per Task.
Any ideas?
Thanks and regards!
Holger
