@Markus: you can not use byte-arrays with google app engine. You have
to use blobs! See my previous solution.
I put the library in myApplication/lib

Add the library to your lib directory and add
bean id=multipartResolver
class=is.hax.spring.web.multipart.StreamingMultipartResolver
/bean
to your applicationContext.xml
For saving the image in a google blob i used the following functions:
@Persistent
Blob imageBlob
byte [] getImage(){
if(imageBlob){
imageBlob.getBytes()
}else{
null;
}
}
void setImage(byte [] imageBytes){
imageBlob = new Blob(imageBytes)

You need the jar file, you can download it from:

Hi
Here is my configuration using StreamingMultipartResolver in my AppEngine
MVC application.
In my servlet context file:
bean id=multipartResolver
class=is.hax.spring.web.multipart.StreamingMultipartResolver
/bean
Then in my model:
private MultipartFile picture;
// getters and setters
And finally in the contoller:
public String uploadPicture(@ModelAttribute(picture) Picture picture)
{
MultipartFile file = picture.getPicture();
byte[] rawData = file.getBytes();
// ...
Hope this helps.

Is there any example on how to use StreamingMultipartResolver in
Spring MVC based web application
(actually grails) like sample xml file configuration settings to
override default spring behaviour?
I am facing the same problem using google app engine because the
framework based on Spring MVC
uses spring file uploads for multipart form requests.

Hi
Check outhttp://github.com/pjesi/springextras
You can use is.hax.spring.web.multipart.StreamingMultipartResolver
I am still working on this so watch for updates.

Hi
CommonsMultipartResolver does write to the filesystem, which is not
what Google wants. I'm working on a special MultipartResolver for the
appengine to resolve this issue. Let me know if you are interested.

Hi all,
I am creating a form that allows the user touploadan image. I use
Spring MVC. I have configured the mulipart resolved as follows:
bean id=multipartResolver
class=org.springframework.web.multipart.commons.CommonsMultipartResolver
property name=maxUploadSize value=200 /
/bean
However, this results in an exception because it tries to write a
temp
file. I know the Commons FileUploadlibrary used support streaming
without actually creating a temp file. Can someome tell me how I
can
configure this in Spring MVC?
Thanks in advance!
