Background
I have banged my head against this for a while and not made much progress. I am generating MPEG_4 / AAC files in Android and sending them by email as .mp3 files. I know they aren't actually .mp3 files, but that allows Hotmail and Gmail to play them in Preview. They don't work on iPhone though, unless they are sent as .m4a files instead which breaks the Outlook / Gmail Preview.
So I have thought of a different approach which is to attach as a .mp3 file but have an HTML link in the email body which allows the attached file to be downloaded and specifies a .m4a file name. Gmail / Outlook users can click the attachment directly whereas iPhone users can use the HTML link.
Issue
I can send an email using JavaMail with HTML in it including a link which should be pointing at the attached file to allow download of that file by the link. Clicking on the link in Gmail (Chrome on PC) gives a 404 page and iPhone just ignores my clicking on the link.
Below is the code in which I generate a multipart message and assign a CID to the attachment which I then try to access using the link in the html part. It feels like I am close, but maybe that is an illusion. I'd be massively grateful if someone could help me fix it or save me the pain if it isn't possible.

You need to create a multipart/related and set the main text part as the first body part.
The attached photo is a representation of my layout.I need to enter the first and last name in the EditTexts. And by pressing the Insert Button, the info is saved to the database. (This part I managed to do) However, on clicking the Show button, the entered input is to be displayed in the TextView which consists of the firstname & lastname. Attached photo
to upload your data into remote database you can use this code
//enregistrement des donnees dans la base de donnees
WebClient client = new WebClient();
Uri uri = new Uri("http://test.com/login.php");
NameValueCollection parameters = new NameValueCollection();
parameters.Add("Email", email);
parameters.Add("Password", password);
client.UploadValuesCompleted += Client_UploadValuesCompleted;
client.UploadValuesAsync(uri, parameters);
it will generate this method
private void Client_UploadValuesCompleted(object sender, UploadValuesCompletedEventArgs e)
{
if (Encoding.UTF8.GetString(e.Result) == "success!!!")
{
Toast.MakeText(this, "success!!!", ToastLength.Long).Show();
}
else if (Encoding.UTF8.GetString(e.Result) == "failed!!!")
{
Toast.MakeText(this, "failed!!!", ToastLength.Long).Show();
}
}
and to retrieve your data you can use code
articles = new JavaList<ModelArticle>();
mWebClient = new WebClient();
mUrl = new Uri(urlAddress);
mWebClient.DownloadDataAsync("your url");
mWebClient.DownloadDataCompleted += MWebClient_DownloadDataCompleted;
it will generate this method
private void MWebClient_DownloadDataCompleted(object sender, DownloadDataCompletedEventArgs e)
{
RunOnUiThread(() =>
{
try
{
string json = Encoding.UTF8.GetString(e.Result);
articles = JsonConvert.DeserializeObject<JavaList<ModelArticle>>(json);
}
catch (Exception exception)
{
Toast.MakeText(this, " Vueillez verifier votre connexion a internet puis reessayer ", ToastLength.Short).Show();
}
});
}
now your result is in the javalist articles don't forget to create a model of your json result
I'm trying to respond to SNMP GET requests from SnmpB with SNMP4j 2.3.1 (running on Windows).
In "Discover" mode, SnmpB queries by broadcasting 255.255.255.255 (checked with Wireshark) and I receive a GET request with standard OID (sysDescr, sysUpTime, sysContact, sysName and sysLocation). It finds my instance with the information I coded ("My System", "Myself", ...) (note that it also works when I enter the IP address under the "IP networks" textboxes, though I don't see any traffic on Wireshark but I receive the GET request):
I did write a very simple MIB file that I imported into SnmpB. It defines a single Integer32 data that I want to retrieve using an SNMP GET request from SnmpB.
However, using the same code than for the standard sys* OID, SnmpB doesn't seem to receive that data ("Timeout" in red on the top-right):
I did try Wireshark to check network activity and I don't see anything, so I guess it takes place on localhost (which is not accessible with Wireshark on Windows)? But the traces below show it does not (peerAddress=192.168.56.1)...
Here is the MIB file (code follows):
MY-TEST-MIB DEFINITIONS ::= BEGIN
IMPORTS
enterprises, MODULE-IDENTITY, OBJECT-TYPE, Integer32
FROM SNMPv2-SMI;
myTest MODULE-IDENTITY

... and the code:

It produces the following output when I click "discover" under SnmpB and right-click on myData in the MIB Tree and "Get" (slightly reformatted for readability):

Stopping...
What am I missing here? Could that "just" be a network routing issue?
After setting up a VM and checking with Wireshark, it turned out I forgot to set, on the response PDU, the same request ID than the GET PDU.
It was solved by adding resp.setRequestID(pdu.getRequestID()); when building the response PDU
CommunityTarget comm = new CommunityTarget(event.getPeerAddress(), new OctetString(event.getSecurityName()));
comm.setSecurityLevel(event.getSecurityLevel());
comm.setSecurityModel(event.getSecurityModel());
PDU resp = new PDU(PDU.RESPONSE, responses);
resp.setRequestID(pdu.getRequestID()); // Forgot that!
snmp.send(resp, comm);
Thanks to #Jolta for his patience during New Year holiday and his insisting on using Wireshark for further checking. :)
Using Groovy 1.8.6 and Grails 2.1.0
Using embedded API, after user signs document, browser is redirected back to my app. Using "Get Envelope Documents and Certificate" API to download document to server. URL format:
"${baseUrl}/envelopes/${envelopeId}/documents/combined"
Code snippet (with minor details removed):
private void getDocument(requestUrl) {
def connection = urlConnect(requestUrl, null, "GET")
if (connection.responseCode == 200) {
savePDF(envelopeId, connection.inputStream)
}
}
private void savePDF(envelopeId, inputStream) {
String filePath = getSavedPDFPath(envelopeId)
def pdfWriter = new File(filePath).newWriter()
pdfWriter << inputStream
pdfWriter.close()
}
What happens is that the resulting file is not 100% correct, Adobe Reader complains that "at least one signature is invalid". Reader at least knows that the file was signed by DocuSign, Inc., and can show details about the certificate.
Per the Question's comment thread, the issue was being caused by the way the file was being saved. Using this code instead, the file saves / opens correctly:
private void savePDF(envelopeId, connection)
{
FileOutputStream fop = null;
File file;
String filePath = getSavedPDFPath(envelopeId);
try {
file = new File(filePath);
fop = new FileOutputStream(file);
byte[] buffer = new byte[1024];
int numRead;
while((numRead = connection.getInputStream().read(buffer)) > 0)
{
fop.write(buffer, 0, numRead);
}
fop.flush();
fop.close();
}
catch (Exception e)
{
throw new RuntimeException(e);
}
}
I am working on an BB app in which I need to maintain a HTTP connection and with a name of image which is stored on server to get the text written in that image document.
I am getting the response in RTF format.
When I directly hit the server on open browser Chrome, I RTF file get downloaded.
Now I needs to perform that programetically,
1) Either convert the bytes which are coming in response in a simple string format so that I can read that.
or
2) Download the file as its happening on the browser manually so that by reading that file I read the information written in the document.
please suggest me how can I read the data from server by hitting any URL?
Currently I am working with this code:
try {
byte []b = send("new_image.JPG");
String s = new String(b, "UTF-8");
System.out.println(s);
} catch (Exception e) {
e.printStackTrace();
}
public byte[] send(String Imagename) throws Exception
{
HttpConnection hc = null;
String imageName = "BasicExp_1345619462234.jpg";
InputStream is = null;
ByteArrayOutputStream bos = new ByteArrayOutputStream();
byte[] res = null;
try
{
hc = (HttpConnection) Connector.open("http://webservice.tvdevphp.com/basisexpdemo/webservices/ocr.php?imgname="+imageName);
hc.setRequestProperty("Content-Type", "multipart/form-data;");
hc.setRequestMethod(HttpConnection.GET);
int ch;
StringBuffer sb= new StringBuffer();
is = hc.openInputStream();
while ((ch = is.read()) != -1)
{
bos.write(ch);
sb.append(ch);
}
System.out.println(sb.toString());
res = bos.toByteArray();
}
catch(Exception e){
e.printStackTrace();
}
finally
{
try
{
if(bos != null)
bos.close();
if(is != null)
is.close();
if(hc != null)
hc.close();
}
catch(Exception e2)
{
e2.printStackTrace();
}
}
return res;
}
The response is like:
{\rtf1\ansi\ansicpg1252\uc1\deflang1033\adeflang1033...................
I can read the data but its not formatted, so that i can read that programetically too.
I have done with this task....
Actually the mistake was on server side.
When they were performing OCR, the format parameter was not corrected that was reason.
