I have started studying to take the Sun Java Programmer certification exam. This 2 hour written exam covers, in excrutiating detail, the core elements of the Java programming language. This exam doesn't focus as much on the Java libraries. That is saved for the Sun Java Developer certification. To prepare for the exam I am working my way through A Programmer's Guide to Java Certification (2nd edition), by Khalid A. Mughal and Rolf W. Rasmussen. This book comes highly recommended from the reviews on Amazon.com. |

Recently I was working on a Java project. The program was intended to run for a long time (weeks at a time) and process incoming requests. I started the overnight test to see how it would do receiving requests over a 12 hour period. After five hours the program crashed with this message: java.io.IOException: Too many open files So I had to dig in and figure out what was causing this. |
