Never did this, but I remember a similar problem when I wanted to copy a JDBCDataSource. I worked around this by setting all the properties manually instead of trying to copy the whole DS.

Followed Professor Manning's suggestion to use the ProtobufAnnotationSerializer and did something wrong.
used serializer.writeCoreDocument on the correctly working document; Later read written file with pair = serializer.read; then used pair.second InputStream p2 = pair.second; p2 was empty resulting in a null pointer when running Pair pair3 = serializer.read(p2);
public void writeDoc(CoreDocument document, String filename ) {
AnnotationSerializer serializer = new
ProtobufAnnotationSerializer();
FileOutputStream fos = null;
try {
OutputStream ks = new FileOutputStream(filename);
ks = serializer.writeCoreDocument(document, ks);
ks.flush();
ks.close();
}catch(IOException ioex) {
logger.error("IOException "+ioex);
}
}
public void ReadSavedDoc(String filename) {
// Read
byte[]kb = null;
try {
File initialFile = new File(filename);
InputStream ks = new FileInputStream(initialFile);
ProtobufAnnotationSerializer serializer = new
ProtobufAnnotationSerializer();
InputStream kis = new
ByteArrayInputStream(ks.readAllBytes());
ks.close();
Pair<Annotation, InputStream> pair = serializer.read(kis);
InputStream p2 = pair.second;
int nump2 = p2.available();
logger.info(nump2);
byte[] ba = p2.readAllBytes();
Annotation readAnnotation = pair.first;
Pair<Annotation, InputStream> pair3 = serializer.read(p2);
kis.close();
} catch (IOException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (ClassCastException e) {
e.printStackTrace();
} catch(Exception ex) {
logger.error("Exception: "+ex);
ex.printStackTrace();
}
}
This line is unnecessary and should be deleted:
Pair<Annotation, InputStream> pair3 = serializer.read(p2);
If you have set up readAnnotation correctly that's the end of the read/write process. p2 is empty because you have read all its contents already.
There is a clear example of how to use serialization here:
https://github.com/stanfordnlp/CoreNLP/blob/master/itest/src/edu/stanford/nlp/pipeline/ProtobufSerializationSanityITest.java
You will have to also build a CoreDocument from an Annotation.
CoreDocument readDocument = new CoreDocument(readAnnotation);
I am having problems getting an image back from the default android gallery. All I want to do is call the Android standard gallery intent and return the uri for the image in my onActivityResult. When I run this code it open the gallery just fine but then it force closes whenever I click on a picture. Any tips for this would be helpful.
private void doGallery() {
Intent galleryIntent = new Intent();
galleryIntent.setType(IJudgeSingleton.IMAGEINTENT);
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(galleryIntent, "Select Picture"), IJudgeSingleton.REQUEST_CODE_GALLERY);
}
case IJudgeSingleton.REQUEST_CODE_GALLERY:
Uri uri = data.getData();
mSingleton.mFileTemp = new File(getMediaPath(uri));
try {
IJudgeSingleton.copy(mSingleton.mFileTemp, mSingleton.mCropFileTemp);
mData.setImageSet(true, mSingleton.mFileTemp.toURI().toString(), true);
mData.setPhoto(true);
}
catch (IOException e) {
Log.d(this.getClass().getName(), "REQUEST_CODE_GALLERY", e);
}
break;
Figured it out my file was pointing to a null so that's what was giving me the force close. Also I had to add change some code around in my onActivityResult for REQUEST_CODE_GALLERY. I have posted the added code below for anyone who has this problem.
case IJudgeSingleton.REQUEST_CODE_GALLERY:
Uri uri = data.getData();
//This takes the uri/image returned from the gallery intent a places it into a file.
final int chunkSize = 1024; // We'll read in one kB at a time
byte[] imageData = new byte[chunkSize];
try {
InputStream in = getContentResolver().openInputStream(uri);
OutputStream out = new FileOutputStream(mSingleton.mFileTemp); // I'm assuming you already have the File object for where you're writing to
int bytesRead;
while ((bytesRead = in.read(imageData)) > 0) {
out.write(Arrays.copyOfRange(imageData, 0, Math.max(0, bytesRead)));
}
in.close();
out.close();
} catch (Exception ex) {
Log.e(this.getClass().getName(),"REQUEST_CODE_GALLERY");
}
// mSingleton.mFileTemp = new File(getMediaPath(uri));
try {
IJudgeSingleton.copy(mSingleton.mFileTemp, mSingleton.mCropFileTemp);
mData.setImageSet(true, mSingleton.mFileTemp.toURI().toString(), true);
mData.setPhoto(true);
}
catch (IOException e) {
Log.d(this.getClass().getName(), "REQUEST_CODE_GALLERY", e);
}
break;
case IJudgeSingleton.REQUEST_CODE_DEFAULT_CAPTURE:
mData = data.getParcelableExtra(IJudgeSingleton.SURVEY_INTENT);
showListView();
completedIntent = false;
In my app I need to download several images from a server. I use this code to get a byte array :
HttpConnection connection = null;
InputStream inputStream = null;
byte[] data = null;
try
{
//connection = (HttpConnection)Connector.open(url);
connection = (HttpConnection)Connector.open(url, Connector.READ_WRITE, true);
int responseCode = connection.getResponseCode();
if(responseCode == HttpConnection.HTTP_OK)
{
inputStream = connection.openInputStream();
data = IOUtilities.streamToBytes(inputStream);
inputStream.close();
}
connection.close();
return data;
}
catch(IOException e)
{
return null;
}
The url are formed with the suffix ";deviceSide=false;ConnectionType=MDS - public" (without spaces) and it is working perfectly well.
The problem is that with phones that do not have a sim card, we can't connect to the internet via the MDS server. So we changed to use the connection factory and let BB choose whatever he wants :
ConnectionFactory connFact = new ConnectionFactory();
ConnectionDescriptor connDesc;
connDesc = connFact.getConnection(url);
if (connDesc != null)
{
final HttpConnection httpConn;
httpConn = (HttpConnection)connDesc.getConnection();
try
{
httpConn.setRequestMethod(HttpConnection.GET);
final int iResponseCode = httpConn.getResponseCode();
if(iResponseCode == HttpConnection.HTTP_OK)
{
InputStream inputStream = null;
try{
inputStream = httpConn.openInputStream();
byte[] data = IOUtilities.streamToBytes(inputStream);
return data;
}
catch(Exception e)
{
e.printStackTrace();
return null;
}
finally{
try
{
inputStream.close();
} catch (IOException e)
{
e.printStackTrace();
return null;
}
}
}
}
catch (IOException e)
{
System.err.println("Caught IOException: " + e.getMessage());
}
}
return null;
The connection works because it select the good prefix (interface=wifi in our case), but this create another problem.
Some images are not well downloaded, some of them (not the sames at each try) are corrupted, but only when the phone use a wifi connection to get these images.
How can I avoid this problem ? What method to get a connection do I have to use ? Is it possible to check if the user have a sim card in orderto use MDS - public ?
Here is an example of a corrupted image :
error image http://nsa30.casimages.com/img/2012/06/28/120628033716123822.png
try this:
public static String buildURL(String url) {
String connParams = "";
if (WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED) {
connParams = ";interface=wifi"; //Connected to a WiFi access point.
} else {
int coverageStatus = CoverageInfo.getCoverageStatus();
//
if ((coverageStatus & CoverageInfo.COVERAGE_BIS_B) == CoverageInfo.COVERAGE_BIS_B) {
connParams = ";deviceside=false;ConnectionType=mds-public";
} else if ((coverageStatus & CoverageInfo.COVERAGE_DIRECT) == CoverageInfo.COVERAGE_DIRECT) {
// Have network coverage and a WAP 2.0 service book record
ServiceRecord record = getWAP2ServiceRecord();
//
if (record != null) {
connParams = ";deviceside=true;ConnectionUID=" + record.getUid();
} else {
connParams = ";deviceside=true";
}
} else if ((coverageStatus & CoverageInfo.COVERAGE_MDS) == CoverageInfo.COVERAGE_MDS) {
// Have an MDS service book and network coverage
connParams = ";deviceside=false";
}
}
Log.d("connection param"+url+connParams);
//
return url+connParams;
}
private static ServiceRecord getWAP2ServiceRecord() {
String cid;
String uid;
ServiceBook sb = ServiceBook.getSB();
ServiceRecord[] records = sb.getRecords();
//
for (int i = records.length -1; i >= 0; i--) {
cid = records[i].getCid().toLowerCase();
uid = records[i].getUid().toLowerCase();
//
if (cid.indexOf("wptcp") != -1
&& records[i].getUid().toLowerCase().indexOf("wap2") !=-1
&& uid.indexOf("wifi") == -1
&& uid.indexOf("mms") == -1) {
return records[i];
}
}
//
return null;
}
What happens when you append interface=wifi? Can you run the network diagnostic tool attached to below kb article and run all tests with SIM removed

Please also note that when download large files over BES/MDS there are limits imposed by MDS. Please ensure you review the below kb article

You can check to see if coverage is sufficient for BIS_B (MDS public) but that won't help you if you are trying to support SIM-less users. I wonder if the problem is in an incomparability between the connection on Wi-Fi and IOUtilities.streamToBytes(). Try coding as recommended in the API documents.
I have researched and tried to refer back to my fileChooser.getSeletedFile() in my save as action but can not work out how to check whether or not a file has been created. Here is my attempted code so far:
Save as code(works well):
public void Save_As() {
fileChooserTest.setApproveButtonText("Save");
int actionDialog = fileChooserTest.showOpenDialog(this);
File fileName = new File(fileChooserTest.getSelectedFile() + ".txt");
try {
if (fileName == null) {
return;
}
BufferedWriter outFile = new BufferedWriter(new FileWriter(fileName));
outFile.write(this.jTextArea2.getText());//put in textfile
outFile.flush(); // redundant, done by close()
outFile.close();
} catch (IOException ex) {
}
}
"Save" code doesn't work:
private void SaveActionPerformed(java.awt.event.ActionEvent evt) {
File f = fileChooserTest.getSelectedFile();
try {
if (f.exists()) {
BufferedWriter bw1 = new BufferedWriter(new FileWriter(fileChooserTest.getSelectedFile() + ".txt"));
bw1 = new BufferedWriter(new FileWriter(fileChooserTest.getSelectedFile() + ".txt"));
String text = ((JTextArea) jTabbedPane1.getSelectedComponent()).getText();
bw1.write(text);
bw1.close();
} else {
Save_As();
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
Instead of storing an instance to the JFileChooser rather store an instance to the File (wich will be null before any save has been performed). In your SaveActionPerformed method check if the file is null. If it is null then do a Save_As and store the selected file in your file variable, if it is not null then do a normal save into the file.
I want to get the XML in atom format of a GoogleDocs spreadsheet using the [generateAtom(..,..)][1] method of the class BaseEntry which a SpreadsheetEntry inherits. But I don't understand the the second parameter in the method, ExtensionProfile. What is it and will this method call suffice if I just want to get the XML in atom format?
XmlWriter x = new XmlWriter();
spreadSheetEntry.generateAtom(x,new ExtensionProfile());
[1]: http://code.google.com/apis/gdata/javadoc/com/google/gdata/data/BaseEntry.html#generateAtom(com.google.gdata.util.common.xml.XmlWriter, com.google.gdata.data.ExtensionProfile)
From the JavaDoc for ExtensionProfile:
A profile is a set of allowed
extensions for each type together with
additional properties.
Usually if you've got a service, you can ask that for its extension profile using Service.getExtensionProfile().
Elaborating Jon Skeet's answer, you need to instanciate a service like this:
String developer_key = "mySecretDeveloperKey";
String client_id = "myApplicationsClientId";
YouTubeService service = new YouTubeService(client_id, developer_key);
Then you can write to a file using the extension profile of your service:
static void write_video_entry(VideoEntry video_entry) {
try {
String cache_file_path = Layout.get_cache_file_path(video_entry);
File cache_file = new File(cache_file_path);
Writer writer = new FileWriter(cache_file);
XmlWriter xml_writer = new XmlWriter(writer);
ExtensionProfile extension_profile = service.getExtensionProfile();
video_entry.generateAtom(xml_writer, extension_profile);
xml_writer.close();
writer.close();
} catch (IOException e) {
e.printStackTrace();
}
}
Analogously, you can read a file using the extension profile of your service:
static VideoFeed read_video_feed(File cache_file_file) {
VideoFeed video_feed = new VideoFeed();
try {
InputStream input_stream = new FileInputStream(cache_file_file);
ExtensionProfile extension_profile = service.getExtensionProfile();
try {
video_feed.parseAtom(extension_profile, input_stream);
} catch (ParseException e) {
e.printStackTrace();
}
input_stream.close();
} catch (IOException e) {
e.printStackTrace();
}
return video_feed;
}
