Yesterday I asked on this site for an Exception that I didn't know how to handle, and I luckily found an answer in a very short time. Well.. here's another one. The class is the same of the other question: when I download messages from the imap server and handle them into an array, it gives me IMAPAddress Exception. This time I really don't know what I could do, I don't want to use POP3 because I just want to see emails stored on the server, not really handle them. Thank you for the attention.
Here's the code:
ScaricaEmail(String host,String porta,String user,String pw)
{
this.host=host;
this.porta=porta;
nick=user;
this.pw=pw;
}
public static Object[][] checkMail(String cartella)
{
Object[][] tabella;
try
{
Properties propvals = new Properties();
propvals.put("mail.imaps.host", host);
propvals.put("mail.imaps.port", porta);
propvals.put("mail.imaps.starttls.enable", "true");
propvals.put("mail.imaps.ssl.trust", "*");
Session emailSessionObj = Session.getDefaultInstance(propvals);
//Create IMAP store object and connect with the server
Store storeObj = emailSessionObj.getStore("imaps");
storeObj.connect(host, nick, pw);
//Create folder object and open it in read-only mode
Folder emailFolderObj = storeObj.getFolder(cartella);
emailFolderObj.open(Folder.READ_ONLY);
//Fetch messages from the folder and print in a loop
Message[] messageobjs = emailFolderObj.getMessages();
tabella=new Object[messageobjs.length][6];
for(int i = 1; i <= messageobjs.length; i++)
{
Message m = messageobjs[i-1];
String mimeType = m.getContentType();
Object[] risultati=new String[6];
risultati[i-1]=m.getFrom()[i-1]; //Here's where I get the Exception
risultati[i-1]=m.getSubject();
risultati[i-1]=getTestoDaMessaggio(m);
risultati[i-1]=getContoAllegati(m);
risultati[i-1]=m.getSentDate();
risultati[i-1]=0;
tabella[i-1]=risultati;
}
emailFolderObj.close(false);
storeObj.close();
}
catch (Exception exp)
{
exp.printStackTrace();
tabella=null;
}
return tabella;
}
Here's the output:

Thank you.
Object[] risultati=new String[6];
risultati[i-1]=m.getFrom()[i-1]; //Here's where I get the Exception
Message.getFrom() returns an Address[] and you are getting the first index which is an Address. Address is not a java.lang.String so it can't be stored in a String[].
To make it work you could do something like:
risultati[i-1]=String.valueOf(m.getFrom()[i-1]);
Or you can change the array type:
Object[] risultati=new Object[6];
In general, you avoid coping values to an array and just use the message object.

I send a document over socket like this:
sendFXML(asByteArray(getRequiredScene(fetchSceneRequest())));
private void sendFXML(byte[] requiredFXML) throws IOException, TransformerException {
dataOutputStream.write(requiredFXML);
dataOutputStream.flush();
}
private Document getRequiredScene(String requiredFile) throws IOException, ParserConfigurationException, SAXException, TransformerException {
return new XMLLocator().getDocumentOrReturnNull(requiredFile);
}
private String fetchSceneRequest() throws IOException, ClassNotFoundException {
return dataInputStream.readUTF();
}
On the side of XMLLocator it finds the correct document and parses it right. I see it by printing the whole doc in console.
But I cannot handle it on the clients side where it's fetch by:
public static void receivePage() throws IOException {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
byte[] data = new byte[989898];
int bytesRead = -1;
while((bytesRead = dataInputStream.read(data)) != -1 ) { //stops here
baos.write(data, 0, bytesRead );
}
Files.write(Paths.get(FILE_TO_RECEIVED), data);
}
After the first iteration in while() cycle it just stops on the commented place.
I don't know if I have an error on the side of the server and I send this in doc in an incorrect format or I read the sent byte array incorrectly. Where is the problem?
Edit:
For the debug purpose, in the receivePage() method, I've chosen a different way of reading the byte array from server which goes like:
int count = inputStream.available();
byte[] b = new byte[count];
int bytes = dataInputStream.read(b);
System.out.println(bytes);
for (byte by : b) {
System.out.print((char)by);
}
And now I'm able to print fetched FXLM in console but a new problem has appeared.
On debug, it normally receives the byte[] from server, writes 2024 for count and displayes the content of the file but if I run the app normally via Shift + f10 it fetches nothing and just writes 0 in console
Edit2:
For some reason, once again, on debug, it's able to even write into a file
for (byte by : b) {
Files.write(Paths.get(FILE_TO_RECEIVED), b);
System.out.print((char)by);
}
But when I try to return this fxml on debug and then show like this:
Parent fxmlToShow = FXMLLoader.load(getClass().getResource("/network/gui.fxml"));
Scene childScene = new Scene(fxmlToShow);
Stage window = (Stage)((Node)ae.getSource()).getScene().getWindow();
window.setScene(childScene);
return window;
It shows only previous files. Like on the first attempt of debug it show a blank page when I asked for the 1st one from server. On the second attempt of debug when i ask for 3rd page from server, it shows me the previously asked one and so on.
To me, it seems absolutely insane cuz the fxml rile actually refreshes before the line
Parent fxmlToShow = FXMLLoader.load(getClass().getResource("/network/gui.fxml"));
is invoked.
Yeah, thank everybody for participating.
So, the issue of incorrect displaying if FXML files was caused by the incorrect FILE_TO_RECEIVED path.
When FXMLLoader.load(getClass().getResource("/network/gui.fxml")); loads gui.fxml it takes it not from D:\\JetBrains\\IdeaProjects\\Client\\src\\network\\gui.fxml,im my case, but from D:\\JetBrains\\IdeaProjects\\Client\\OUT\\PRODUCTION\\Client\\network\\gui.fxml.
As for me, that doesn't seem obvious.
What about different behaviour on debug and on run. In method receivePage() it needs to wait until connection is available.
int count = inputStream.available();
If you read docs for this method you will see
Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream ...
The available method for class InputStream always returns 0...
So, you jext need to wait for connection to be available
while(inputStream.available()==0){
Thread.sleep(100);
}
Otherwise it just prepares byte[] b = new byte[count]; for 0 bytes and you can write in nothing.
I try to receive some messages from a POP3 mail server using the apache POP3 mail client.
I use a BufferedReader to get messages from my POP3 mail server (retreiveMessage(id)). I have some mails with long lines and I read them with a loop like below. My lines are truncated into several lines ending with the equal sign (=), each line with 76 chars plus the =.
import org.apache.commons.net.pop3.POP3Client;
import org.apache.commons.net.pop3.POP3MessageInfo;
...
POP3Client pop = new POP3Client();
pop.setSocketFactory(SSLSocketFactory.getDefault());
pop.setDefaultTimeout(60000);
pop.connect(MAIL_SEREVR, PORT);
String username = USERNAME;
String password = PASSWORD;
isVerified = pop.login(username, password);
POP3MessageInfo[] messages = pop.listMessages();
for (POP3MessageInfo msginfo : messages) {
Date timestamp = new Date();
BufferedReader reader = (BufferedReader) pop
.retrieveMessage(msginfo.number);
if (reader == null) {
System.err.println("Could not retrieve message header.");
pop.disconnect();
System.exit(1);
}
try {
printMessageInfo(reader, msginfo.number, timestamp);
} catch (Exception e) {
e.printStackTrace();
}
pop.deleteMessage(msginfo.number);
}
pop.logout();
pop.disconnect();
So, I print the messages and since a word is too long, it is truncated like this:
this is a short line, it is OK
andThisIsALongLineWithMoreThan76CharactersButThisIsEmpiricalIJustSeeThatThe=
LineIsTruncatedAtThe76thCHAR
is this a normal behavior? can someone help me?
thanks
It doesn't sound like you're using JavaMail. It you aren't, use it, it will make life easier for you. If you are, explain in more detail what you're doing.
In my app I tried to pass the file path from one activity to another activity using intent.In my receiving activity I got the file path as "null".But when I print the file in first activity it prints the path.From my second activity I attach that file to mail using Gmailsender.This was the code I tried,
private void startRecord()
{
File file = new File(Environment.getExternalStorageDirectory(), "test.pcm");
try
{
file.createNewFile();
OutputStream outputStream = new FileOutputStream(file);
BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(outputStream);
DataOutputStream dataOutputStream = new DataOutputStream(bufferedOutputStream);
int minBufferSize = AudioRecord.getMinBufferSize(8000,
AudioFormat.CHANNEL_IN_MONO,
AudioFormat.ENCODING_PCM_16BIT);
short[] audioData = new short[minBufferSize];
AudioRecord audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC,
8000,
AudioFormat.CHANNEL_IN_MONO,
AudioFormat.ENCODING_PCM_16BIT,
minBufferSize);
audioRecord.startRecording();
while(recording)
{
int numberOfShort = audioRecord.read(audioData, 0, minBufferSize);
for(int i = 0; i < numberOfShort; i++)
{
dataOutputStream.writeShort(audioData[i]);
}
}
audioRecord.stop();
audioRecord.release();
dataOutputStream.close();
}
catch (IOException e)
{
e.printStackTrace();
}
String audiofile;
audiofile=file.getAbsolutePath();
System.out.println("File Path::::"+audiofile);
}
Intent is,
Intent sigout=new Intent(getApplicationContext(),WeeklyendActivity.class);
sigout.putExtra("mnt/sdcard-test.pcm",audiofile);
startActivity(sigout);
In my receiving activity,
String patty=getIntent().getStringExtra("mnt/sdcard-text.pcm");
System.out.println("paathhhy frfom ::"+patty);
It prints null.Can anyone help me how to get the file path.And more thing I am not sure whether the audio would save in that file correctly?
Please anyone help me!!!Thanks in advance!
Based on your information that audioFile is a variable of type File, when you do this:
sigout.putExtra("mnt/sdcard-test.pcm",audiofile);
you are putting a File object in the extras Bundle. Then, when you try to get the extra from the Bundle you do this:
String patty=getIntent().getStringExtra("mnt/sdcard-text.pcm");
However, the object in this extra is of type File, not type String. This is why you are getting null.
If you only want to pass the name of the file, then put the extra like this:
sigout.putExtra("mnt/sdcard-test.pcm",audiofile.getAbsolutePath());
I am dealing one serious problem and seems i cannot find a logical solution.
Here it goes.
I have a string array in my code (jsp file). I want to pass the array in the same page , and i thought of making the array a session and call it again later in my code but it seems that i cannot take the session (with get.Attribute) and make it an array again. TO be more specise the following code might help you.
while (onomaq.next()) {
String onomatemp = onomaq.getString("one1");
String[] onoma = onomatemp.split(" ");
out.println(onoma[2]);
session.setAttribute("onoma", onoma);
}
} catch (Exception e) {
System.out.println("SQL Exception: " + e.toString());
}
%>
<%
try{
Object o = session.getAttribute("onoma");
String k=o.toString();
String[] name=k.split(",");
out.println(name[1]);
}
catch (Exception e)
{
System.out.println("SQL Exception: " + e.toString());
}
the out.println gives me a message lige [L.java.String and some characters.
Can anyone help me please?
Rather than calling toString() on your array object after obtainig it from session, just cast the object reference to an array (since your object IS an array) and use it.
This means, replace this code:
Object o = session.getAttribute("onoma");
String k=o.toString();
String[] name=k.split(",");
with
String[] name= (String[]) session.getAttribute("onoma");
p.s. purpose of toString() is somwhat different from what you seem to expect. See Javadoc.
String[] expected_array= (String[]) session.getAttribute("onoma");
Then run it inside a loop to retrieve. Example:
for(int i = 0; i < expected_array. length; i++)
{
String strings = expected_array[i] ;
}
I created an application which stores values into the database and retrieves the stored data. While running an application in run mode everything seems to work fine (the values are stored and retrieved successfully) but when I run in the debug mode the process throws IllegalStateException and so far haven't found a cause.
The method which retrieves an object Recording is the following:
public Recording getRecording(String filename) {
Recording recording = null;
String where = RECORDING_FILENAME + "='" + filename + "'";
Log.v(TAG, "retrieving recording: filename = " + filename);
try {
cursor = db.query(DATABASE_TABLE_RECORDINGS, new String[]{RECORDING_FILENAME, RECORDING_TITLE, RECORDING_TAGS, RECORDING_PRIVACY_LEVEL, RECORDING_LOCATION, RECORDING_GEO_TAGS, RECORDING_GEO_TAGGING_ENABLED, RECORDING_TIME_SECONDS, RECORDING_SELECTED_COMMUNITY}, where, null, null, null, null);
if (cursor.getCount() > 0) {
cursor.moveToFirst();
//String filename = c.getString(0);
String title = cursor.getString(1);
String tags = cursor.getString(2);
int privacyLevel = cursor.getInt(3);
String location = cursor.getString(4);
String geoTags = cursor.getString(5);
int iGeoTaggingEnabled = cursor.getInt(6);
String recordingTime = cursor.getString(7);
String communityID = cursor.getString(8);
cursor.close();
recording = new Recording(filename, title, tags, privacyLevel, location, geoTags, iGeoTaggingEnabled, recordingTime, communityID);
}
}
catch (SQLException e) {
String msg = e.getMessage();
Log.w(TAG, msg);
recording = null;
}
return recording;
}
and it is called from another class (Settings):
private Recording getRecording(String filename) {
dbAdapter = dbAdapter.open();
Recording recording = dbAdapter.getRecording(filename);
dbAdapter.close();
return recording;
}
While running through the code above everything works fine but then I notice an exception in another thread:
alt text http://img509.imageshack.us/img509/862/illegalstateexception.jpg
and don't know neither what is the possible cause of this exception nor how to debug the code from that thread to diagnose the cause.
I would be very thankful if anyone knew what is the possible issue here.
Thank you!
Looks like that cursor.close() is inside an "if" - that's when SQLiteCursor.finalize() will throw an IllegalStateException (I googled for it). You migh be getting an empty recordset, for instance, if some other process/thread didn't have the time to commit.
Close it always, even if it's result set is empty.
I'd also advice you to access fields by names, not indices, for future compatibility. And do both close()s in finally{} blocks.
