multipart request gives a bad request syntax(code 400) with jersey 1.x as provider

[GoogleCodeExporter]

When using jersey as provider i always get a code 400( bad request syntax) when 
using multipart requests(multipart/mixed or multipart/form-data). I have this 
issue with version 0.4 , 0.5m1 and with the latest 0.5 compiled from the git 
source.( using jersey 1.2 to 1.9.1). 

I do not have the issue with a standalone test java application using jersey 
1.9.1 or with the restlet provider(with Representation entity instead of jersey 
Multipart) 

import com.sun.jersey.multipart.MultiPart

@POST
String create(final MultiPart multiPart)
{
   return "hello world";
}

Can you also please attach/insert the HTTP request you used for testing? Thanks.

i have tried and used with the same result request from:

1) simple enctype="multipart/form-data" form

2) http client

Ok thanks. I'll take a look as soon as I can (I'm currently very busy with a 
customer project).

I found the reason why this doesn't work (and can provide a workaround).

Reason:

When submitting a multipart request to Grails, one of its servlet filters uses 
a multipart resolver that parses the request i.e. reads all parts from the 
request's input stream. This is the reason why Jersey cannot process the 
multipart request: the input stream is already read. It therefore throws an 
exception which causes a 400 response (bad request).

Workaround:

Disable Grail's multipart request parsing in Grails. This can be done by adding 
grails.disableCommonsMultipart=true to Config.groovy and 

class BootStrap {
    def grailsApplication
    def init = { servletContext ->
       grailsApplication.config.'grails.web.disable.multipart' = true
    }
}

to BootStrap.groovy. More info at 
http://grails.1312388.n4.nabble.com/Disable-MultipartResolver-td3560222.html

Issues:

Disabling Grail's multipart resolver can have consequences when submitting 
forms from a GSP for example (see Grails docs). If your app doesn't provide a 
GUI then this shouldn't be an issue. 

I'll leave this ticket open because I still want to find a way how to support 
multipart request processing with grails-jaxrs while having the Grails 
multipart resolver enabled as well.

Any news with this issue? Because the workaround doesn't work anymore in Grails 
2.0 and plugin 0.6:

In grails 2.0 at startup with workaround enabled you get:

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 
'multipartResolver' is defined
    at org.grails.jaxrs.web.JaxrsFilter.doFilterInternal(JaxrsFilter.java:41)

Sorry, didn't work on that yet. Do you want to fix it and make a contribution? 
WDYT?

Cheers,
Martin

Well i'm happy to help but i'm not an expert in the inner workings of your 
plugin. But i can share my thoughts with you. 

I think we should concentrate to make the 'workaround fix' work again in grails 
2.0 by optionally be able to disable the grails multipart resolver. Instead of 
finding a way to support grails-jaxrs while having the Grails multipart 
resolver enabled as well. 

I think this because the only 'grails accepted' way at this time to proces raw 
request is by disabeling the multipart resolver completely:
http://jira.grails.org/browse/GRAILS-1254 

So if you agree , do you have a clue why the workaround works in grais 1.3.x 
and in grails 2.0 and plugin version 0.6 your plugin throws this at startup?: 
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 
'multipartResolver' is defined
    at org.grails.jaxrs.web.JaxrsFilter.doFilterInternal(JaxrsFilter.java:41)

Hi Michael, 

thanks for your response. Your proposal sounds good to me. I didn't have time 
so far to investigate why the workaround doesn't work any more with Grails 2.0. 
If you could find it out yourself and get it working with grails-jaxrs 0.6 this 
would be of great help for me.

Cheers,
Martin

I discovered it has nothing to do with the plugin. A clean Grails 2.0 app fails 
to start with grails.disableCommonsMultipart=true in the Config.groovy. 
It results in:

ERROR filter.UrlMappingsFilter  - Error when matching URL mapping [/]:No bean 
named 'multipartResolver' is defined

So disabling the multipartResolver does not seem possible in Grails 2.0 at this 
time. I'll post an Issue.

Cheers Michael

Thanks for reporting this issue at Grails. Cheers, Martin

Hi friends, i was having the problem described above, and i solved this putting 
these two in the Config.groovy:

grails.disableCommonsMultipart=true
grails.web.disable.multipart=true

Now evething is working fine! :)

My grails is 2.0.3 and i'm using jaxrs 0.6
