Hi,

You have to post a multipart form data message to the REST service.
For example using Apache FileUpload.

Best regards,

Hi,
thank you for providing information and i tried with Multipart Form data message and i got null pointer exception in server.

Please suggest me on this. I used below code.If possible provide me sample code.

regards,
suresh

public static void main(String[] args) throws IllegalStateException, IOException {
// TODO Auto-generated method stub

DefaultHttpClient dhc = new DefaultHttpClient();

dhc.getCredentialsProvider().setCredentials(new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, AuthScope.ANY_REALM), new UsernamePasswordCredentials("kermit", "kermit"));

HttpPost hp = new HttpPost("http://localhost:8080/activiti-rest/service/deployment");


hp.addHeader( "Content-Type", "multipart/form-data; boundary=—————————28617237579832" );
// Create AuthCache instance
AuthCache authCache = new BasicAuthCache();
// Generate BASIC scheme object and add it to the local auth cache
BasicScheme basicAuth = new BasicScheme();
authCache.put(new HttpHost("localhost", 8080, "http"), basicAuth);

// Add AuthCache to the execution context
BasicHttpContext localcontext = new BasicHttpContext();
localcontext.setAttribute(ClientContext.AUTH_CACHE, authCache);

MultipartEntity se = new MultipartEntity();
File file = new File("E:/mule/DistributeWorkflow/src/test/resources/demotest.bpmn20.xml");
se.addPart("success", new StringBody("success", Charset.forName("UTF-8")));
se.addPart("failure", new StringBody("failure", Charset.forName("UTF-8")));
FileBody fileBody = new FileBody(file);
se.addPart("deployment", fileBody);

hp.setEntity(se);

HttpResponse processResponse = dhc.execute(hp,localcontext);

String data=IOUtils.toString(processResponse.getEntity().getContent());
System.out.println("reader"+data);

dhc.getConnectionManager().shutdown();

}

Hi,

My problem was solved by commenting
hp.addHeader( "Content-Type", "multipart/form-data; boundary=—————————28617237579832" );
in the above code and now i am able to deploy/upload new workflow.

Thanks and regards,
suresh
