How to check any URL working or not through Java Code

Hi,
Is there any way by which i can check whether any particular URL is working or not using JAVA..
Thanks in advance......

Especially for POSTs, I would use HTTPClient: [http://hc.apache.org/httpclient-3.x/]
For simple GETs, you could just create the URL and then see if openStream works.

  • How to check for a logic bomb in compiled java code ?

    I have couple of security requirements.
    1. How do I check for logic bomb in the compiled java code ?
    2. Is there any way to monitor memory utilized by class when running inside a constructor ?

    1. Let me see if you can define 'logic bomb', then maybe a answer can be supplied. If you simply mean malicious code, then in general you cannot. You can attempt to do the kinds of things that antivirus software does, like check for the existence of known malicious code and code patterns, but that won't work any better on Java than it does on anything else.
    2. Google java profiling. Also, for something relatively simple, read about jconsole.

  • How to send any laguage msg to mobile through java

    Hello friends ,
    i need to send msg which will may be in any language.
    can i do so through java ?
    also is it jms is helpful for this ? or i need to use other package ?

    You'll need to find some sort of online SMS gateway that will inject a SMS message into the mobile phone network for you. I have no experience of these. The mobile phone network is not the internet: you can't access it directly.
    Such a service may or may not be free, and may only support specific telecom networks.
    Try searching for "web service to send sms" using your favourite search engine. When I tried this it came up with several companies offering this service, using a "web service" API (i.e. XML over HTTP).
    You can certainly access web services using Java; there are APIs designed for this purpose. Some are listsed at

    Hi. Running your code, I got the following, with the URL as:
    String dir = "http://california.biocars.org/viewFrames2.php?";
    String fileName = "r=840190844&fn=/data/pub/kb030129_fp_2_001.img&xsize=512&ysize=512&zoom=1&contrast=2048&xcen=0.5&ycen=0.5&wval=0&jpq=100";
    String urlName = dir+fileName;
    URL imageURL = new URL(urlName);
    So something wrong? This output does not look like anything
    of a jpeg file. Thanks.

  • How to check / internet is working or not?

    i need to execute a line of code in java console application only and only when internet is working ie i can access the google page
    to check the internet connection , i try below code,,
    try
            URL url = new URL("http://google.com/");
               URLConnection connection = url.openConnection();
               connection.connect();
            catch( Exception ex)
                // connection can not be established
            }but here, when internet is working, try block successfully execute . when internet is down , it throw an exception on Connection.connect() ,
    connect() is void type , it is not returning anything, that's why i can not handle it.... is there any other way , where i get true or false or any number , when internet is ok, ie www.google.com is responseing..

    connect() is void type , it is not returning anything, that's why i can not handle itWhen an exception is thrown, you have two choices:
    1) Catch it and actually handle it. This means whatever failed, you have to make it work. Maybe by trying again, maybe be providing a default value.
    2) If you cannot to #1, then you should not catch the exception in the first place. Or, if you do catch it, wrap it and rethrow it.
    So, for example, in your case, if your code is:
    Establish connection.
    Use connection.If the "establish" part fails, you obviously can't do the "use" part, and this overall task has failed. That happens sometimes.

  • How Server can read client side SSL certificates through java code?

    My code will be running on server which will be a java class that should read any SSL certificates for the user that is logging in to the application.
    Kindly let me know how it can be achieved ? I have very rare knowldge on Security. how i can read SSL certificates of the client machine.
    Also let me know the possible solutions for above question.

    For my mud written in java, I used TCP/IP for the connections. When a client connects, he gets his own thread. Those threads are held in a vector in a manager class. each tick of the server does a quick run thru the vector and if the current thread/socket its on is null or !isAlive() its remove from the vector(which in turn removes it from getting any more game updates. This removal can be caused by two things. The clients disconnects by accident(kills his game, locks up has an internet connection hiccup, etc.) or he uses the games "quit" method. The quit method calls a method that does any player saving of data, etc then closes the socket, and sets it to null. thus the manager sees this and removes him frm the vecotr list on the next server tick. Seems to work great form a mud and worked really well in a multiplayer applet game I had up for a while.

    Thanks in advance
    Solved!

    At Least according to the NI TestStand 2012 documentation, Engine.FindPath and Engine.FindFile work only within the NI TestStand SearchDirectories.
    Maybe related: remote paths (\\server\path\to\file.ext) are considered "invalid" by Engine.FindPath.

  • How to check internal table sorted or not

    Hi all
    I need to check internal table sorted or not which is without header line and having only one field and six values. please let me know how to check it is sorted or not because i need to display message if it is not sorted.
    thanks,

    Hi Minal,
    Go through  this info.
    Sorted tables
    This is the most appropriate type if you need a table which is sorted as you fill it. You fill sorted tables using the INSERT statement. Entries are inserted according to the sort sequence defined through the table key. Any illegal entries are recognized as soon as you try to add them to the table. The response time for key access is logarithmically proportional to the number of table entries, since the system always uses a binary search. Sorted tables are particularly useful for partially sequential processing in a LOOP if you specify the beginning of the table key in the WHERE condition.
    Stable sort
    The option
    SORT <itab> ... STABLE.
    allows you to perform a stable sort, that is, the relative sequence of lines that are unchanged by the sort is not changed. If you do not use the STABLE option, the sort sequence is not preserved. If you sort a table several times by the same key, the sequence of the table entries will change in each sort. However, a stable sort takes longer than an unstable sort.
