  • how to send an array of bytes over a TCP connection (java programming)

    - by Mark Roberts
    Can somebody demonstrate how to send an array of bytes over a TCP connection from a sender program to a receiver program in Java. (I'm new to Java programming, and can't seem to find an example of how to do this that shows both ends of the connection (sender and receiver.) If you know of an existing example, maybe you could post the link. (No need to reinvent the wheel.) P.S. This is NOT homework! :-)

  • Simple startup on boot of misc application (Java based) on Ubuntu Linux 8+ as a daemon

    - by Berlin Brown
    What is the easiest way to have an application launch at startup on Ubuntu server as daemon? This is a java application (java com.run.run.Run) etc. How would I have it launch as a user and possibly have access to write to some log file where the user has permissions to write? And if I don't end up doing that, how would I launch the application as the root user at startup. Edited: It is a headless server, I don't have access to the desktop applications.

    - by user271858
    We are about to roll out a client server application build with java web start. Our main server is located in a country in Europe and we will have many users downloading our client the first day from all over the world. Since the client application is quite big in MB our wan will be utilized a lot. Is there a way to cache or pre- distribute java web start clients to servers "closer" to the user (for example a local server)? Thanks.

  • Is there a java library equivalent to `file` command in unix

    - by Shervin
    Is there any java libraries that is similar to unix's command file? ie: $ file somepicture.png somepicture.png PNG image, 805 x 292, 8-bit/color RGB, non-interlaced The file command is such a nice tool. I need something that can tell me if the file is really what I want it to be. (ie a picture, document etc) I know I can run the command file, but I am looking for a java library, not running the actual unix command.

    - by Kaveh Shahbazian
    1 - Is it possible for a developer to use Scala without knowing Java? 2 - Is it possible for a developer to use Clojure without knowing Java? Note: For example I am a C# developer and I use .NET without knowing any VB (Of-course WF 4.0 uses VB for statements, so I refuse any projects involving WF 4.0 :) ).

  • Paste a multi-line Java String in Eclipse

    - by Thilo
    Unfortunately, Java has no syntax for multi-line string literals. No problem if the IDE makes it easy to work with constructs like String x = "CREATE TABLE TEST ( \n" + "A INTEGER NOT NULL PRIMARY KEY, \n" ... What is the fastest way to paste a multi-line String from the clipboard into Java source using Eclipse (in a way that it automagically creates code like the above).

  • Detecting and handling third-party library filehandle leaks in Java

    - by tucuxi
    Is there any way to detect and handle whether a Java library is correctly releasing file-handles (via "close") from within a Java program that is using said library, short of having access to the actual library code and inserting the corresponding "finally close" statements? If detection is feasible, is there any way to close those file-handles without a reference to the Reader (or FileInputStream) that was reading the file?
