My apologies. You presumably resolved your problem or gave up trying to use DrJava. Here is my belated explanation:</p> <p>It appears that your firewall is blocking interprocess communication via TCP/IP on your local machine. This is odd because modern operating system enable such communication by default. DrJava uses two Java virtual machines that communicate via Java RMI which relies on TCP/IP on the local machine. You need to allow Java to access your network.</p></div>Robert CartwrightWed, 18 Sep 2013 13:50:11 -0000https://sourceforge.netf5764093cd9e415e11b64ec5bca2cf7b91bbc791Firewall Compilation Running Problem Help ASAP pleasehttps://sourceforge.net/p/drjava/support-requests/300/<div class="markdown_content"><p>So I wrote a small program for my programming class and I know that is correct because it compiled but when I tried running it I received this error:</p> <p>JVM failed to start.
