Java Servlet/Jsp image upload along with form values -

i have jsp form accepts details employee name, sex, age, e-mail address ,

servlet 3.0 container's has standard support multipart data. first should writing html page takes file input along other input parameters.

<form action="uploadservlet" method="post" enctype="multipart/form-data">     <input type="text" name="name" />     <input type="text" name="age" />     <input type="file" name="photo" />     <input type="submit" /> </form> 

now write uploadservlet uses servlet 3.0 upload api. here code demonstrates usage of api. fist servlet handling multipart data should define multipartconfig using of 2 approaches:

• @multipartconfig annotation on servlet class
• in web.xml, adding <multipart-config> entry inside <servlet> definition.

here uploadservlet,

@multipartconfig  public class uploadservlet extends httpservlet  {    protected void service(httpservletrequest request,         httpservletresponse responst) throws servletexception, ioexception    {       collection<part> parts = request.getparts();       if (parts.size() != 3) {          //can write error page saying details not entered        }         part filepart = httpservletrequest.getpart("photo");        inputstream imageinputstream = filepart.getinputstream();        //read imageinputstream        filepart.write("somefiepath");        //can write photo local storage         //read name, string type         part namepart = request.getpart("name");        if(namepart.getsize() > 20){            //write name cannot exceed 20 chars        }        //use nameinputstream if required                inputstream nameinputstream = namepart.getinputstream();        //name , string type can obtained using request parameter         string nameparameter = request.getparameter("name");         //similialrly can read age properties        part agepart = request.getpart("age");        int ageparameter = integer.parseint(request.getparameter("age"));        }  } 

if not using sevlet 3.0 container, should truing apache commons file upload. here links using apache commons file upload:
