I managed to attend the DJUG meeting tonight (as I wrote this, time slid past midnight - oh well, it looks better on a new day). I arrived early for the Basic Concepts meeting and stayed for the Main Event. Both sessions were focused on Struts - the first being a very basic overview of MVC and Struts, and the second highlighted the newest features (i.e. Declarative Exception Handling, Validator, DynaActionForms). Like I said earlier, I wanted to meet Sue in person, so that's why I got there early. I introduced myself and she actually seemed to remember me (from the e-mails). I confirmed that she really did remember me (or she faked it quite well) at the end when she signed a copy of her book (that I won) - she asked me if I spelled my name with one "t" or two? Cool! BTW - do you know anybody named "Mat?"
When the DJUG Prez asked if anyone was looking for work, I raised my hand and said a few words about this site and Roller. I doubt anyone will find this site though; I didn't see anyone writing my domain name down, and how the heck do you spell "Raible?" So to offer a little Google love, here are a few different versions: Rabel, Riable, Raibel, Raybel, Rable, Raybell. If I was really bold, I guess I could send an e-mail to the DJUG Mailing List. I think I'll have to pass though, I'm just not that forward of a guy.
The meeting was packed, probably a 100 people showed up - most they've had in long time from the way they were talkin'. It was at DU, my Alma Mater, so it was fun to visit the ol' stompin' grounds. I had Mini-Me with me and found the DU Wireless network, but it required VPN software to get in (and my old id/pass didn't work to d/l the software).
Sue was a good speaker and did manage to impress me with her Struts knowledge. I didn't know that she is a contributing author of the JSP and Servlets column at O'Reilly's OnJava.com, nor that she's got a list of seemingly great publications. I tried to give her a tip about XDoclet, but she said she already knew about it and was planning on mentioning it in her preso. Doh! She really put me in my place. The best part of her presentation (for me) was the declarative exception handling, which I tried to implement on my current project, but it was too immature and buggy at the time. I think it's time to re-examine and refactor.
As a service to my readers, and possibly to readers from the meeting, here is a whole posse of good Struts links:
I'd love to see some weblogs published by Sue or Chuck (Cavaness) - it'd be great to see more Struts Evangelists in the blogging community. The next meeting should be good. Marc Fleury, founder of JBoss fame is going to be speaking.
Russell linked to a picture of me this morning. I don't think it does me any justice since I'm run ragged from Abbie's birth and I'm sitting there with 15 pregnancy-pounds. So, in hopes of improving my image (nudge, nudge), here is a picture of Julie and I from March of this year.
I managed to revive Mini-Me this afternoon just after I thought I had lost everything. After running Disk Repair (from both the OS X and OS 9) CDs about 20 times, I tried the Archive and Install again. This time it worked (the disk was recognized) and I get to start re-configuring everything, just like I did one month ago.
Thank goodness - I'd hate to lose all those sweet photos from Abbie's birthday. I'm burning a CD (of all my photos) as I write and backing up everything. I guess this is my monthly almost-hose-the-machine and rebuild sequence. I used to do it on my XP machine, and I do it about every 6 months to Julie's Win2K box. I've gone a couple years now without killing anything completely, but I have re-installed Windows many times - haven't lost any data yet. Must be time to backup everything, now that I've written this, a disk failure is inevitable.
Domininic says, "I am try to find a good way to have an intermediate page load up while my Struts Action performs a large database query and then XSLT transformation." Ask and ye shall receive. I received the following e-mail from Alec Missine a while back. The attachment has a method of implementing a TCR. Let me know how it works as I haven't tried it myself.

Subject: processing time consuming requests (was: wait page primer)
There's been some interest to the message I posted last month on the subject. The war file was too big though, so I compressed the stuff as much as I could. I also added some javadoc and UML diagrams.
The attached Struts-based application prototypes the wait page support for a time-consuming request (TCR). When a TCR (e.g., a database search) starts, the appropriate wait page is being sent to the browser after the request's ETC (Estimated Time to Complete) expires.
In the meantime, the corresponding action (the database search) is being started in the background thread on the server. If the default ETC is used (ad infinitum) or the action completes before the request's ETC expires, there is no wait page at all - the browser gets the result page right away, while the background thread is still busy closing the resources.
This implementation has been tested on Apache Tomcat 4.0 with an Oracle 8.1.6 database as a data source. Presently, the application provides read-only access to all database tables for all database schemas through extensive use of the java.sql.DatabaseMetaData object. The next release will support insert/update/delete functionality.
