Java uploader (jersey) make all service down

I want to have very very simple uploader in a rest service which not working with html form, and get files from an android device.

this is my code:

@Path("test")
@POST
@Consumes({MediaType.MULTIPART_FORM_DATA})
public String testing(@FormDataParam("img") InputStream fileInputStream,
@FormDataParam("img") FormDataContentDisposition contentDispositionHeader ){
String SERVER_UPLOAD_LOCATION_FOLDER = "/var/lib/openshift/57a83e6f0c1e66920000005a/"
+ "app-root/runtime/repo/downloads/users/";
String filePath = SERVER_UPLOAD_LOCATION_FOLDER + contentDispositionHeader.getFileName();
saveFile(fileInputStream, filePath);
String output = "File saved to server location : " + filePath;
return output;
}
private void saveFile(InputStream uploadedInputStream,
String serverLocation) {

try {
OutputStream outpuStream = new FileOutputStream(new File(serverLocation));
int read = 0;
byte[] bytes = new byte[1024];

outpuStream = new FileOutputStream(new File(serverLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
outpuStream.write(bytes, 0, read);
}
outpuStream.flush();
outpuStream.close();
} catch (IOException e) {

e.printStackTrace();
}

}


but when I push this code all of my rest services take down and give error 500.(I mean other rest uri path). for example if I want to access
myserviceuri/resturi/login
it gives error 500 too.

HTTP Status 500 - Servlet.init() for servlet restService.restStarter threw exception

note: restService.restStarter is my first file that have:

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

/**
*
* @author Seyed Ali
*/
@ApplicationPath("RestApi")
public class restStarter extends Application {

}


I relized that this this two line:

@FormDataParam("img") InputStream fileInputStream,
@FormDataParam("img") FormDataContentDisposition contentDispositionHeader


cause the error and when I remove this from my test file other files work well.

pleaseeeee help me.

Answer

I finally solved it. for who have this problem: the problem is about to using @Path()

in this case you have to write two @Path, first one upper of your class and the second one upper of your method and if you want to do all of this in a one simple path you should do this:

@Path("/")
public Class classname {
     @Path("yourPath")
     @Consumes("multipart/form-data")
     public method(){
          .
          .
          .
     }
}
