Hi,
I am using RestEasy on the client side (version 2.2.1.GA) and trying to
upload a huge file and I get a OutOfMemory Error:
Caused by: java.lang.OutOfMemoryError: Java heap space

It seems that this issue was addressed a long time ago using mime4j:
https://issues.jboss.org/browse/RESTEASY-233
<https://issues.jboss.org/browse/RESTEASY-233>
I do have mime4j in my classpath but not sure if there is something I
need to do differently to make this work?
Here is my code:
The JAX-RS annotated interface:
@Path("/resource")
public interface RestClientAPI {
@POST
@Path(UPDATE_PRODUCTS_ASYNC_RESOURCE)
//@Consumes(MediaType.APPLICATION_XML)
@Consumes(MediaType.MULTIPART_FORM_DATA)
@Produces(MediaType.APPLICATION_XML)
Response upload(@MultipartForm final LoaderMultiPartForm loader);
}
The MultiPartForm class:
public class LoaderMultiPartForm {
@FormParam("loader")
@PartType(MediaType.APPLICATION_XML)
private Loader loader;
@FormParam("bulkProductTypeStream")
@PartType(MediaType.APPLICATION_OCTET_STREAM)
private InputStream bulkProductTypeStream;
public Loader getLoader() {
return this.loader;
}
public void setLoader(Loader loader) {
this.loader = loader;
}
public InputStream getBulkProductTypeStream() {
return this.bulkProductTypeStream;
}
public void setBulkProductTypeStream(InputStream
bulkProductTypeStream) {
this.bulkProductTypeStream = bulkProductTypeStream;
}
}
The Call:
RestClientAPI client =
factory.getClient(CatalogResource.class);
Loader loader = new Loader();
loader.setXXX();
LoaderMultiPartForm loaderForm = new
LoaderMultiPartForm();
loaderForm.setLoader(loader);
hugeFileUploadStream = new BufferedInputStream(new
FileInputStream(new File("C:\\tmp\\hugeFileToUpload.txt")));
loaderForm.setBulkProductTypeStream(hugeFileUploadStream);
client.upload(loaderForm);
Appreciate any help.
Regards,
Sandeep.
