Even I am setting Java heap memory size to 1028MB in eclipse for my
testing in development mode
i am not able to upload a file.

i was saw some forums setting java heap size
java -Xms5m -Xmx1028m MyApp

can you please give me suggetions how to resolve this problem using
eclipse and tomcat.



Thanks in advance ,

This was nothing to do with GWT, try to add more memory to your servlet container JVM.

As Rudolf said, this has nothing to do with GWT. Perhaps you should
look at apache commons upload Streaming API:
http://commons.apache.org/fileupload/streaming.html

Thanks for giving suggetion,
this is not related to GWT,
but  i am facing when i set upload maximum file size to(1024MB - 2GB), but it is giving same error,

Hi Raj,

I think this will not work in general.
On 32 Bit-System Java is limit to somewhat betwenn 1.5-2GByte memory.

Uploading GByte Files may excete this limit. I suspect an upload may
need twice twice the memory in java.

I would consider a different mechanism when uploading such big files
(java-applet, flash, WebDAV..)

due to recent cases, I am sorry, I won't do free personal support.
inquiries for professional GWT support are welcome.

Hi Stefan Bachert,

Thanks for giving suggestion, i will try on this issue as you told for increasing memory.

stop doing that,

its not your intention to load the entire filestream into the
memory?! :-)

you'd be better off with streaming, so on doPost() in your servlet you
could acquire a stream from the request and forward it to your
outputstream on the file system, so only the internal buffer is used.
IN case of huge upload I would not use tools which provides you API on
byte[] level. Apache also has support for fileupload - but its is not
that package which is used to access forms data (there is no streaming
support)

br,
