Larry Williams points out how to monitor Tomcat 5.5.x with JMX.
To monitor your Tomcat instance with JMX start Tomcat with the following JVM parameters.
-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9000 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false
I'm posting this hear so it's easier to find when I get time to try this out.
From the iBATIS mailing list:
Hi everyone, I just wanted to remind everyone of Alex Egorov's sql2iBatis tool. I've recently had the chance to try it. If you have a database that's already created, this will save you a lot of time. It will kickstart your project. Given DDL, it generates the SQL Mapping files and the JavaBeans. It's super simple and extremely fast. You may want to tweak the Perl to generate bean field naming conventions to your liking, or just refactor it afterwards. You might also want to run the source through Jalopy or your favorite IDE formatter to achieve the formatting you want. However you cut it, this tool will save you tons of time (even if you don't use everything it generates...deleting is faster than writing). http://alxeg.narod.ru/ibatis/index.html Cheers, Clinton
Too bad it's a perl script. It would be nice to add something like this to AppFuse so you could get the same generate-mapping-files thing like Hibernate has with XDoclet.
So most folks think Struts is Dead, huh? I've got news for you folks. Struts has been dead since 2002. For that matter, most Java frameworks have been dead for the last year. Most folks think Struts is dead because there won't be any new and whiz-bang features added in future releases. I'm willing to bet the other Java Web Frameworks won't add any whiz-bang features in the next few years either. Sure, WebWork might get a little XMLHttpRequest lovin' for client-side validation, and Tapestry might get pretty URLs - but both of these are features that these frameworks should've had in the first place. So what's the big deal? At least the Struts Developers have the guts to stand up and say "we're in maintenance mode". Shouldn't all framework developer's be able to say this? It's really quite an accomplishment.
IMO, the only developers that shouldn't be saying this are Tapestry and JSF folks. Both of these teams should be saying - "we're going to make our frameworks easier." If these frameworks are going to be the future of Java web development, there's some work to do. The JSF folks should be saying, "we're going to fix all the stuff that's broken". This "stuff" includes POST for everything, lack of bookmarkability, and bad validation messages (the good news is the validation messages should be fixed in JSF 1.2). I think Tapestry needs some simplification too. In my experience, most Tapestry pages (by design) require 4 files. One for the Java class, one of the HTML template, one for the page specification and one for the i18n keys. This should be easier. It'd like to see two required files (template and Java class) and the others are optional. Maybe annotations could eliminate the page specification? I think there's a lot to be learned from frameworks like Ruby on Rails: default everything, allow overriding.
I think that Shale will be good, but only if it learns from the other MVC frameworks available. If I were on the team, I'd take the good things from all the others: IoC, Interceptors, HTML templates, etc. I wouldn't stop there either - there needs to be good examples of how to integrate it with middle-tier frameworks like Spring, Hivemind and EJBs. Often developers will take examples as recipes - so the more detailed and simple, the better. The Struts developers have quite an opportunity to make something great, let's hope they don't just create another framework.
Dion wants to see an AppFuse Startup Video like Mike Clark's CruiseControl Action Movie. While this sounds like a good idea, I think I'd be shooting myself in the foot if I created it. Why? Because then more folks would start to use AppFuse, and hence, I'd have to answer a lot more e-mails on the mailing list. Being a top-ranked project on java.net doesn't help. You might think that there's a lot of issues with AppFuse, and that's why the mail traffic is so high, but that doesn't seem to be the case. Most questions seem to be along the lines of "Why did you do this?", "What do you think about adding X technology?" or "My Hibernate relationships don't work."
Few of the issues relate to AppFuse directly (i.e. build file and directory structure), but many of them relate to the technologies it depends on. Good HowTos should lead to a lot less Hibernate questions, and I hope to work on that before the next release. As far as the other questions, I need to add some links from the FAQ to the mail archives so I can quite repeating myself. I think a lot of the mail traffic is just an indication of a successful open-source project. In other words, when you get popular - you have little time to develop anymore. I probably spend 1-2 hours per day just answering AppFuse e-mails.
Another unfortunate side-effect of this is that there seems to be a lot of newbies. When AppFuse was first released in April 2003, it seemed that only experienced, smart developers used it. Maybe this was because there wasn't any documentation (besides Pro JSP and Java Development with Ant, which explains the entire build.xml file), so folks had to really understand the dependent technologies to use AppFuse. Now there's questions about the basics of different frameworks. In most cases, I'd like to respond to a link to the framework's documentation - but sometimes the documentation just isn't there. I guess that's why frameworks like Ruby on Rails succeed - all the dependencies are part of the framework. If I tried to do that in the Java Community, it'd be project suicide. I'd spend all day answering questions like, "Why aren't you using Hibernate?", "Why Not Spring/JSF/Struts, etc." Furthermore, I'm not as smart as the framework developers, so it'd simply never happen.
But I digress. What's in it for me if I create an AppFuse Startup Video? I can see what's in it for Mike - his video is about a project he doesn't support (AFAIK) and the video should lead to more book sales. I suppose I could try and hook users that AppFuse is explained in Spring Live, but that's not really the case. Maybe I should just do an Equinox Startup Video. 
I've gotten several e-mails from readers that they haven't been able to leave comments on this blog. I suspect it has something to do with twisty comments, but I just tried them in Firefox 1.0 on Windows XP and they seem to be working fine. In order to help me track down this problem, try posting a comment to this entry and see if it works. Make sure and copy it before you post it, just in case it doesn't work. Clicking on the "Permalink" or title for this post will take you to a backup comment form that seems to work regardless. Thanks for the help!
Update: From the various comments, there doesn't seem to be a common thread. It seems that half the folks that used Firefox + XP it worked for and the other half it didn't. I doubt it's a caching issue, but I have been seeing a lot of the following in my logs:
ERROR 2005-01-22 19:51:01,944 | RequestProcessor:processMapping | Invalid path /comment was requested
Roller recently changed from using /comment to /comments - so I don't know if it's spammers hitting the old URL or what. My guess is yes since it seems to happening in blocks. I'll try to add a preview button tonight so users will get taken to the permalink form for previewing. Either that or I could just change to always using the permalink form. It's up to you guys - let me know what you prefer.
I've been using Maven at my new gig and the Maven Console in order to avoid its painfully slow startup times. Using a slow-ass PowerBook in conjunction with Maven makes my face turn read and my ears smoke sometimes, but I'm getting used to it, much to my dismay. While the console has made things tolerable, Maven itself keeps getting in the way. I hate how it *requires* me to run my tests everytime I build or deploy. So I've turned that off by creating a build.properties file with "maven.test.skip=true". The problem with the Maven Console is it doesn't let me turn tests back on, so I'm stuck with running "maven test -Dmaven.test.skip=false" when I want to run my tests.
There's two ways I can think of to solve this problem:
According to the Gentoo Java Roadmap, AppFuse is on the list of apps to integrate. Nice! I'm going to rebuild my Windows 2000 Server as a Suse 9.2 box in the next couple of weeks, but I might have to reconsider and go with Gentoo. I was going to buy a gig o' RAM for the box, but it looks pretty spendy.
Today I added another item for AppFuse 1.8 in the roadmap: create an installer using MyJavaPack that can install Ant, AppFuse, MySQL and Tomcat. Basically, give developer's a way to install and start developing with AppFuse in under 5 minutes. Let me know if you're interested in helping out with this.
According to quite a few sources, Apple will be shipping PowerBook G5s in the next 6 months. The timing sounds right. Tiger will be shipping by the Developer's conference and they need to announce something big - so G5 Laptops sounds like a logical choice. I can wait 6 months - where can I pre-order a 17"?
At work today, I put together a config.xml for CruiseControl to run continuous integration builds for our project. We're using Maven, so I used the CruiseControl Plugin to generate a cruisecontrol.xml file to get started. Then I moved this file up a few directories, renamed it to config.xml and changed all the log paths to be outside of the project.
There's quite a difference between running CruiseControl with Ant vs. Maven. With Ant - you tend to delete the whole project, check it out from CVS and build/test it from scratch. With Maven, the recommendation seems to be a bit different. What I found on the mailing lists and such was that you should manually checkout your project into your "checkout" directory and then call "scm:update-project|clean test" from config.xml. With Maven, it seems there's no CruiseControl-specific maven.xml file for your project.
I tend to like the delete/checkout/test approach you get with Ant over the update/test approach with Maven. For those of you that are using CruiseControl with Maven - is it possible to do delete/checkout/test - or am I stuck with the update/test approach?
A friend recently sent me an e-mail looking for advice on becoming an independent consultant and specifically how to get contracts. I thought this advice might be interesting for others. The e-mail below is unmodified for the most part. He's an animator and does a lot of stuff in Flash, so this naturally has that twist to it. For Java Developers, just replace Macromedia/Flash stuff with Java stuff.
The best thing is to subcribe to the job mailing lists in Denver.
There's a Rocky Mountain Internet Users Group and Macromedia Users
group that would probably help you.
http://www.rmiug.org/html/email_lists.html
http://www.rm3ug.com
Then I would advise you to get involved in with a local user group,
like the Macromedia one. Attend meetings, talk to people, see where
they're getting their gigs. I go to the Denver Java Users Group on a
monthly basis and now I have a lot of friends there. It was nerdy at
first, but then I realized they all went out for beers afterwards and
it's kinda cool now. If you volunteer to speak at one of the
meetings, you'll probably get some leads from that. It's really all
about networking.
The best thing you could possibly do for you career and new clients is
to start a weblog. On it you can talk about what you do and how you
solve problems. Tips and tricks kinda stuff. I put a lot of
personal stuff on mine (www.raibledesigns.com) too. Ever since I
started my weblog, I haven't had to do much looking. Often, I can
just post I'm looking for a new gig and I'll get offers. I get 8000
visitors a day and around 2 million hits a month. It's the main
reason I got my last couple of book deals.
Any other advice you might have for people looking to become independent consultants?
In general, I find independent consulting a lot more fun than full-time employment. The main benefits of full-time employment are Health Insurance and 401K Plans. Stock options are not a benefit in my eyes. I've yet to meet anyone who has made money off stock options as a full-time employee.
The main benefits of being an independent consultant are higher pay and freedom. An experience full-time Java Developer (in Denver) makes around $100K year. I've heard of companies hiring employees for $120K, but the most I've known anyone to make is $108K. On other hand, a contractor with only a year or two of experience can easily make $55/hour - or $110K year. Experienced developers get anywhere from $75/hour to $200/hour. That's right folks - $150K year to $400K year! For the higher dollars you often have to travel, which kinda sucks.
People that are full-time employees often like it for the benefits - health care and such. As a consultant, you get to see how screwed up our health care system is and pay for your health insurance out-of-pocket. I've seen folks pay anywhere from $250/month to $1000/month for health insurance. We've done both (the latter thanks to Corba) and I'm happy to say that we're paying $250/month now. United Healthcare, minimal plan - but we're still insured. What about 401K? As an independent, you often will establish your own company, and then you can contribute to an SEP plan. With a 401K, you're limited to contributing something like $15K/year. With an SEP, you can contribute up to $40K! Granted, you won't have any employer matching, but you can still plan for your retirement.
The one downside I've seen personally from being independent is I tend to find a lot of projects where I'm the development team. This is great at first since I can work remotely and don't have to attend any meetings, but I tend to miss the water-cooler talk and synergy that a team provides. With full-time positions, this can happen too, but it's rare. With full-time positions, you're likely part of a development team - and if you're lucky - one full of smart developers. One myth about contractors is that they often don't fit into a team full of full-time employees. Personally, I've found this to be a personality thing and have rarely had issues fitting in with full-time employees. The ideal situation is simply to work with smart people. In my career, working with people smarter than me has always been very lucrative to my knowledge base.
Working from home is not all it's cracked up to be. I've done it off and on for a few years now and I'd much rather go into an office at this point. When I work from home, dinner tends to be a just a "break" in my day and I go back to work after the kids go to bed. When I'm in an office, the work day ends when you leave. So how do you get the team-benefits as a independent consultant? The best way I've found is to work with a group of consultants on a project - where the whole team is contractors. You'll often share the same lifestyle and attitudes about your careers. Also, a lot of independent consultants tend to be smart - so you get that benefit.
The last thing I like about independent consulting is freedom. I had 4 months last year where I attended conferences, went on vacation or worked on Spring Live. Good luck finding that kind of freedom with a full-time gig. The higher rates allow you to take more time off to spend with your family - or just enjoy life in general.
If you're thinking about becoming an independent consultant, now is a better time than ever - especially if you live in Denver. The Denver JUG mailing list received more job postings last year than any previous year. From what I've seen, at least half of these are for contracting positions. Unfortunately, most of them are in the $40-60/hour range, but that's still good money.
Any feedback on why you think being a full-time employee is better is most welcome.
