<div class="markdown_content"><p>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:</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>

<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. Make sure a firewall is not blocking <br /> inter-process communication. See the console tab for details.<br /> JVM failed to start. Make sure a firewall is not blocking <br /> inter-process communication. See the console tab for details.<br /> JVM failed to start. Make sure a firewall is not blocking <br /> inter-process communication. See the console tab for details.</p> <p>then:<br /> java.io.IOException: Unable to run process; class path may need to be adjusted<br /> at edu.rice.cs.plt.concurrent.ProcessTaskController$1.run(ProcessTaskController.java:157)<br /> at java.lang.Thread.run(Unknown Source)<br /> java.io.IOException: Unable to run process; class path may need to be adjusted<br /> at edu.rice.cs.plt.concurrent.ProcessTaskController$1.run(ProcessTaskController.java:157)<br /> at java.lang.Thread.run(Unknown Source)<br /> java.io.IOException: Unable to run process; class path may need to be adjusted<br /> at edu.rice.cs.plt.concurrent.ProcessTaskController$1.run(ProcessTaskController.java:157)<br /> at java.lang.Thread.run(Unknown Source)</p> <p>Im wondering what is wrong and what I need to do.</p></div>
