JRun Closed Connection

If you've noticed an increase in the frequency of "JRun Closed Connection" errors since having migrated to ColdFusion MX 6.1, then you may want to know one factor that is very likely contributing to that increase.


Speaking generally, web requests from the client browser are recieved by the web server and passed to the JRun webserver connector stub. The webserver connector stub communicates with the JRun server on the JNDI port over TCP/IP, typically port 51010. The web request is sent from the connector to the JRun server, and the JRun server will either assign the request to a JVM thread in the running request pool for immediate execution or JRun will assign the request to a thread in queued request pool if the running pool is full.

See You at CFUN04?

Steven Erat ... See you at CFUN04!One week from today I'll be heading from Boston to Washington D.C. & Rockville for the annual CFUN conference, appropriately named CFUN04 this year. Its an 8 hour drive on a Friday night, and the return home won't be until after midnight on Sunday, but this ColdFusion conference is definitely worth it and its growing every year. I've gone for the past 3 years, and I've written the game show questions for CF Jeopardy in 2002 and CF Celebrity Squares in 2003 used in that part of the event .




See you there!






He3 - An Eclipse-based IDE for ColdFusion, from RichPalette Inc.

RichPallete, Inc., a new joint venture between Gestaltech, Inc. and R337 Consulting LLC, announced today the development of He3, a ColdFusion IDE based on the popular Open Source software Eclipse. He3 is expected to provide support for HTML, CSS, XML, SQL, and RegEx, as well as support for the ColdFusion frameworks FuseBox and Mach-II. RichPallete will be distributing Beta versions of the He3 product at the upcoming ColdFusion Conference, CFUN 04.


I found the product name He3 to be rather clever. The atomic particle He3, an isotope of Helium and energy source, is derived from nuclear fusion reactions that occur on stars such as our Sun, and is carried by solar winds and deposited on the Moon. He3 could be mined from the lunar deposits to power both civilizations on Earth and beyond. Sun, Moon, fusion, eclipse, energy, ... They must have given this name a lot of thought. More...

Macromedia to Port Products to Wine

I'm a little late to catch this, but while once again working on getting HomeSite+ 5.5 and Dreamweaver MX 2004 to run under WINE on Fedora Core 1 Linux (see previous blog), I came across a very interesting news article from the recent Flash Forward conference regarding WINE.

BNUG Linux BootCamp

The Boston Network Users Group will be presenting a 1 day "bootcamp" introduction to Linux on Saturday, March 20 from 8:30 to 4:30, at Mount Ida College in Newton, MA.† I'm always looking to pick up useful bits of Linux information, tips, and tricks whenever I can, so I'll be there.†


Topics:




  • Introduction to Linux including considerations in selecting a distribution.


  • Basic Linux Commands, common directories and file structures.


  • Advanced Applications including networking and desktop applications.


  • System Administration: user accounts, privileges, and security considerations.


The cost is $100 in advance or $115 at the door.† Seating is limited, so for more information and to register see the BNUG website.

Molecular Biology and IT Classes at Harvard Extension School

The Harvard Extension School offers a great selection of courses in both Biology and Computer Science, making a great combination of classes to help ramp up on Bioinformatics. Having been working in IT for 4+ years now, I've been growing rusty on my Biology skills and knowledge, and in an effort to refresh myself and make some gains towards my interest in Bioinformatics I've decided to take a couple courses this semester.


Starting tomorrow, I'll be taking Principles of Genetics and Biochemistry II, on Monday evenings. In addition, I'll be adding to my programming skills with XML with J2EE on Thursday nights.


Thinking ahead a bit, this sequence might be well followed by the Genomics and Computational Biology and Introduction to Proteomics in for the Fall semester, and then Web Services in the Spring of 2005.


On a related note, the Bio-IT World Expo will be held in Boston again, March 30 - April 1, at the Hynes Convention Center. Although I have attended some of the past I3C meetings, I feel that I'm still a bit premature to get much out of this year's conference. I think I'll be better prepared to attend the expo in 2005.


Ten years ago I completed Neurobiology, Signal Transduction, and Molecular Biology at the Harvard Extension School, and more recently a Java course. I feel that enables me to make a fair comparison. I elieve that the quality of courses at Harvard, with regard to both the faculty and facilities, is superior to any of the other local universities also catering to the continuing education crowd. I especially enjoyed the MolBio class by David Dressler at Harvard. Dr. Dressler was especially articulate, comfortable, and knowledgeable in front of the class, although I don't see any courses benefiting from his instruction in recent semesters.


At Brandeis, I took an Intro to XML course, an Advanced Java course, and a Cell Biology course, and only the XML course met my expectations for faculty, and all of them fell way short in my expectations for quality of facilities. All of the CS courses at Brandeis@Night are held in a single deteriorating building with poor HVAC, kindergarten-like wooden chairs, and sardine-like seating arrangements. My advice is to avoid Brandeis if at all possible.

See You At MAX!

For anyone going to MAX, the Macromedia Conference 2003 held in Salt Lake City, Utah, I'll be manning the Product Support Lab station along with several of my other colleagues including Brandon Purcell, David O'Leary, and Stephanie Juma. We'll also be assisting many of the hands-on presentations, and we'll be at the Product Support Reception for those of you in attendance.


Bring your questions! See the schedule, but the Support Lab will be open from about 11:30 - 7:00. You can also find me in the Macromedia Max Intro application.

John Terpsta, co-founder of the Samba Team, To Speak in Boston

November Meeting for Boston Network User Group


Speaker: John Terpsta, co-founder of the Samba Team


Subject: Samba 3.0


Teaser: Do you wish for network software that enables IT professionals to have it all? To work within Windows, Linux/UNIX or both? Sound too good to be true? Well, it does exist, in the form of the Samba software, maintained by a global network of volunteers known as the Samba-Team. Long trusted as stable file and print server software, Samba is now creating a groundswell, triggered by the long-awaited release of the latest version, Samba 3.0.0, which has been getting rave reviews from professionals in the field. There are currently 14-16 million servers running Samba, with an expected 3 million soon to migrate, according to Samba-Team Co-Founder John Terpstra.
