I’m coding a GeoServer web service and would like to support a method where there is XML for the main request and then a zip-file as well. I’m having trouble figuring out how to reference the zip file in my service code.
I’m sending geoserver a multipart form as input and this gets processed in the Dispatcher, as it uses ServletFileUpload to parse the request. When Dispatcher loops thru the return from ServletFileUpload.parseRequest it saves the individual FileItems into the kvp map if FileItem.isFormField() returns true. Otherwise the dispatcher assumes the item is an XML file and passes its reader to request.setInput.
In my case isFormField() will be false for both the xml and zip. There are two files in the post. One is the application/xml for the body of the request and the other is the application/zip for the zip file.
If I attach the body (xml) last, my XML will get parsed successfully because a reader for the body ends up being the last thing passed to Request.setInput(). But then the zip file attachment is not available at all because it got discarded by the dispatcher since it was a file attachment and therefore not put into the kvp map. If I attach the body first, the zip file ends up being the last input passed to Request.setInput() and the whole method fails because this can’t be read by geoserver as a valid method request.
I can easily send the XML as a form-field instead of a file, and I see this code that supports a form-field called “body”….
if (request.getInput() == null) {
FileItem body = kvpFileItems.get(“body”);
if (body != null) {
request.setInput(fileItemReader(body));
kvpFileItems.remove(“body”);
}
}
But this code will not run because request.getInput() is NOT null because it got set a few lines up when isFormField() on the zip file returned false.
Can anybody help me with how to proceed? It seems like if my multipart request has a zip file on it then that will be passed to request.setInput(). Then the code never makes into my service because later on geoserver uses that to figure out what the request is.
