I have a server that stores a plain text file with a numerical value. The text file is constantly edited by the server every few minutes or so. What is the best way for an Android Client to retrieve the text file's contents?
The most efficient way would be using Volley library with a string request.
Do something like this:
URL url = new URL("http://www.domain.com/file.txt");
URLConnection urlConnection = url.openConnection();
urlConnection.setConnectTimeout(1000);
InputStream is = urlConnection.getInputStream();

Using Body->form-data you can put your file and a JSON file(.json extension) with your JSON content.

I want to create a server which receives both text and image. For text I used DataInputStream dis.readUTF(), and for image, I used ObjectInputStream ois.readObject() to read the image as byte[]. So how can I write code to detect the data receiving is text or byte[]?
You'll have to use some kind of signal from the client to know whether it is sending text or an image.
Alternatively, you could receive on different ports depending on the type of input.

I want to store image (upload) in database and retrieve it to jsp page. i am using JAVA and SQL SERVER 2012.
My table is imgtbl(name nvarchar(500),photo image)
Please help me
see this link for how to save an image to a DB. I am not sure that nvarchar is correct and I would rather go for a blob or similar.
Relevant code from link
("insert into save_image(name, city, image, Phone) "+ "values(?,?,?,?)");
psmnt.setString(1,"mahendra");
psmnt.setString(2,"Delhi");
psmnt.setString(4,"123456");
fis = new FileInputStream(image);
psmnt.setBinaryStream(3, (InputStream)fis, (int)(image.length()));
see also http://technet.microsoft.com/en-us/library/ms378813.aspx for a Microsoft bent on things.
Convert the image to bytes and save in database as blob.

I want to extract data from sites. I already got information from sites using the article extractor but now I want to get the information about events of a particular place. I want to get the events in that place when I give location as input.For example I want to extract information from this site "http://www.indianevents.org/events-Rajasthan-14.htm" I could be able to extract all events,festivals etc.
URL url;
url = new URL(str);
InputSource is = HTMLFetcher.fetch(url).toInputSource();
BoilerpipeSAXInput in = new BoilerpipeSAXInput(is);
TextDocument doc = in.getTextDocument();
news=ArticleExtractor.INSTANCE.getText(doc);
consider Apache Tika to download the text content
you can use stanford pos tagger to parse the text into
meaningful sentences
and NLP can help identify event information.
although writing this might sound simple (trust me its difficult).
Good Luck. :)
