java - File Upload With Jersey Not Working -

i can't jersey file upload work. using jersey 1.9. inputstream null when gets service. i've tried normal form submission , ajax submission using jquery form plugin, same result either way. there no exceptions logged either, making more frustrating.

html form

<form id="doccategoryform" name="doccategoryform" action="someaction" method="post" enctype="multipart/form-data"> document <input type="file" name="fileupload_name" id="fileupload_name" > <button id="submitbutton" type="submit" title="select search">submit</button> </form> 

pom

<dependency>     <groupid>com.sun.jersey</groupid>     <artifactid>jersey-json</artifactid>     <version>1.9</version>     <scope>provided</scope> </dependency> <dependency>     <groupid>com.sun.jersey.contribs</groupid>     <artifactid>jersey-multipart</artifactid>     <version>1.9</version>     <scope>provided</scope> </dependency> 

the dependency hierarchy in eclipse shows mimepull.jar 1.6 getting pulled in.

the rest service

@resourcefilters({requestloggingresourcefilter.class}) @post @path(path_upload) @consumes(mediatype.multipart_form_data) @produces(mediatype.application_json) public myresponseobject uploaddocument(@formdataparam("fileupload_name") inputstream file) {   // code } 

if add @formdataparam("fileupload_name") formdatacontentdisposition filedetail, fine, inputstream still null.

here request after trying upload simple text file. looks ok me.

thought should bring closure one. problem ended being dumb. somehow wrong inputstream class had been imported. once changed java.io.inputstream worked expected.
