in this i generate the certificate by Java keytool command-line interface.

@Path("/All")

           @GET

            @Produces("text/plain")

            @GZIP

            public EnvelopedOutput getAllOpenMeetings(@QueryParam("batchsize")

            int batchSize, @QueryParam("offset")

            int offset, @Context

            HttpServletRequest req) {

              String ipAddress = req.getRemoteAddr();

              EnvelopedOutput output=null;

              CustomerBean bean=null;

              try {

                 bean=new CustomerBean();

                bean.setDesc("abc");

                bean.setName("xyz");

                //certificate generation

                FileInputStream stream = new FileInputStream("d:/my_keystore.pfx");

                            KeyStore store = KeyStore.getInstance("pkcs12", "SunJSSE");

                            store.load(stream, "my_password".toCharArray());

                            Enumeration<String> aliases = store.aliases();

                            while (aliases.hasMoreElements()) {

                                System.err.println(aliases.nextElement());

                            }

                            X509Certificate certificate = (X509Certificate)store.getCertificate("my_certificate"); 

                 output = new EnvelopedOutput(bean, MediaType.APPLICATION_XML_TYPE);

                output.setCertificate(certificate);

              }  catch (Exception ex) {

                String result = "Error 500 - Internal Server Error";

System.out.println("exception=="+ex.getMessage());

//                throw new WebApplicationException(Response.status(500).entity(result).build());
