upload product image using restful service

[Texon]

Hello ALL,

I am trying to implement a restful service to upload product's image.
Ofbiz calls a groovy file EditProductContent.groovy for uploading through web browser.

Reference taken from:
https://cwiki.apache.org/confluence/display/OFBIZ/Export+service+using+REST

For testing purpose I have hard coded the productId for now and tried calling the same groovy file.

@POST
        @Path("/uploadProductImage")
        @Consumes(MediaType.MULTIPART_FORM_DATA)
        public String uploadProductImage(BufferedInMultiPart bimp, @Context HttpServletRequest request) {
                try {
                        GenericDelegator delegator = (GenericDelegator) DelegatorFactory.getDelegator("default");
                        GenericEntity product = delegator.findOne("Product", UtilMisc.toMap("productId", "10000"), false);
                       
                        Map<String, Object> context = FastMap.newInstance();
                        //required parameters for groovy
                       
                        context.put("productId", product.productId);
                        context.put("product", product);
                        context.put("delegator", delegator);
                        context.put("request", request);
                        GroovyUtil.runScriptAtLocation("component://product/webapp/catalog/WEB-INF/actions/product/EditProductContent.groovy", null, context);
                } catch (GeneralException e) {
                        e.printStackTrace();
                }
                return "";
               
This code further ends up in HttpRequestFileUpload.java, doUpload method after failing to read the data and throws IOException
HTTP Status 500 - java.io.IOException: waited 21 times, bailing out while still expecting 561465 bytes.


Any guidance would be really helpful.

Thanks
