#300 Firewall Compilation Running Problem Help ASAP please
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:
JVM failed to start. Make sure a firewall is not blocking
inter-process communication. See the console tab for details.
JVM failed to start. Make sure a firewall is not blocking
inter-process communication. See the console tab for details.

then:
java.io.IOException: Unable to run process; class path may need to be adjusted

at java.lang.Thread.run(Unknown Source)

Im wondering what is wrong and what I need to do.
I missed seeing your support request until now. My apologies. You presumably resolved your problem or gave up trying to use DrJava. Here is my belated explanation:
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.
