Find and kill the rmiregistry process (RMI servers) or the tnameservprocess (CORBA) associated with each server. Execute the following server_del scripts (forproject testing convenience) to delete the project files from the servers:sisko>server_del1kirk> server_del2spock>server_del3Starting the Client ApplicationOnce the server programs are running, execute the client application. The application hasa graphical interface using Java Swing. The compile_pgm should have started a bash shell andset the environment. Please check the environment to ensure that JAVA_HOME points to Java1.5, otherwise the application will not work.If the environment still isn’t correct, execute the following commands:kira> /bin/bashbash-2.05a$ . ~cs843/bin/jdk.shbash-2.05a$ export CLASSPATH=$CLASSPATH:.bash-2.05a$ java -classpath . DLDClientThe application will display the graphical user interface as shown in Figure A1.
Figure A1. Graphical user interfaceWhen the user selects a text file, it is retrieved from a server, written to a local filesystemand displayed in the text area to the right <strong>of</strong> the file list (see Figure A2). The “Clear” button canbe used to clear the text area at any time. The text area will be cleared every time a new file isselected.Figure A2. Text file selectionWhen the user selects an Adobe PDF file, it also is retrieved from a server and written toa local filesystem. The application calls a PDF viewer, xpdf, as a separate process whichdisplays beside the application window as shown in Figure A3.
