Images in REST Post as multipart/form-data

Anonymous — Tue, 10 Mar 2015 21:42:32 GMT

Hi, I'm trying to do a rest post using 'tRESTRequest' component that accepts three info text type and one or more images, using "Content-Type: multipart/form-data". I don't know name and quantity of images, so I thought to manage parts of request body via java code in a 'JavaRow' component, but didn't find how to access to it (I tryed all globalMap items, also 'restRequest' child items).
I hope find variable, cast it as 'MultipartBody' and extract a map of multipart parts (name of the part is the key, InputStream representing the part - value), finally make it available to my java component following the 'tRESTRequest'.
Can anyone suggest me the best practice to solve this issue in Talend v5.4?

If I POST a JSON or XML file, it work fine, so I parse input in 'XMLMap' component correctly

Hi, I'm trying continue my REST post service with two field and two images, all optional. It work fine and dataflow goes into the post node only if I pass from client all four inputs, but if the client doesn't pass one or more inputs (all are NULLABLE = true as shown) the data flow doesn't go into the post node.
Where I wrong, help me, thanks.
