I have multiple java installations on my machine and need to use different versions all the time. I have found that the currently used JVM can be changed by the commands update-alternatives and update-java-alternatives, which essentially change the link at /etc/alternatives/java etc.
Using #! r20111125 32-bit and installed Java via corenominal's script. I've now downloaded and installed a Java application I need. It's executed from the command-line with java -jar ... etc. It runs fine, but it looks different to how it looked under Ubuntu and looks nothing like any GTK/OB applications. Do I need to install something to "theme" it?
I have one application to write in C# (I can write that in Java as well)
This application is basically accepts some information from user and using these information we are creating some files on Linux system (This is the idea)
I am trying to establish a chatting application between a server and a client, but the application could not run because of this line of code : message = (String) input.readObject();
because at first, inputStream is null ! any one can help please ?
