Re: JSP support on Felix
Jeffrey, I did this quite a while back on some blog posts for demonstration purposes. The code is old, but perhaps it'll serve as a useful starting point. Here's a couple of posts you might find worthwhile (both support JSP): OSGi and Embedded Jetty - http://techdistrict.kirkk.com/2009/02/02/osgi-and-embedded-jetty/ And an alternative: Embedding OSGi in Tomcat - http://techdistrict.kirkk.com/2009/02/16/embedding-osgi-in-tomcat/ Kirk Knoernschild Author of Java Application Architecture: Modularity Patterns with Examples Using OSGi http://www.kirkk.com http://techdistrict.kirkk.com On May 31, 2012, at May 31, 3:01 AM, Jeffrey Huang wrote: I tried a lot of ways to let Felix support JSP.

[ANN] Java Application Architecture: Modularity Patterns with Examples Using OSGi
Apologies for the blatant advertisement, but want to let you all know that my book, Java Application Architecture: Modularity Patterns with Examples Using OSGi is now available. The book's homepage is http://modularity.kirkk.com. Ironically, the book may not be an ideal fit for those of you already highly proficient with OSGi. It's sweet spot is in helping you articulate the benefits of modularity and designing software applications with a modular architecture in the absence of a good module framework like OSGi. Once folks experience the benefits of modular architecture, their increase in a module framework will hopefully increase too. If you experience this type of adoption hurdle, or know others that do, you may find the book interesting. thanx.

Re: How to start
I've got quite a few tutorials on my website. Check out http://techdistrict.kirkk.com/2009/02/19/osgi-post-summary/ . Then, take a look at the Simple OSGi Service and OSGi and Embedded Jetty examples. There are a few others that show some different development scenarios, as well.

I was trying to follow a tutorial on http://felix.apache.org/site/apache-felix-usage-documentation.html and got stuck. First of all, how to download and install. On the download page I see many jar files. If I want to start Felix and play with it, what is the minimum set I have to download? It says there: - Start Felix from the installation directory by typing: java -jar bin/felix.jar _ How do I get the bin/felix.jar ? Which package contains that? Since it is supposed to be an executable jar, I guessed it might be Main, so I downloaded that. But it is called org.apache.felix.main-1.6.0.jar, not felix.jar. Then I tried it: java -jar org.apache.felix.main-1.6.0.jar and I got the following: No config.properties found. Welcome to Felix. = Then it hangs. So basically I need to understand the following: 1. What to download and where to put it. 2. How to configure and start it. Thanks in advance for your help. Leonid --- This communication may contain confidential and/or privileged information.

Re: Blog on OSGi
Rob, Thank you for the comment on my blog posting. I've responded, but will also take a moment to respond here, as well. I didn't intend to come across as narrowly focused. In fact, I thought I was pretty broadly focused and had made it clear I was talking about OSGi for web application development. I felt I was pretty clear that OSGi proper (Equinox and Felix) is ready for primetime, but the tooling and application platform is not. I'm an OSGi advocate, but it's unrealistic to expect an enterprise developer to glue together the components necessary to develop an enterprise application using OSGi. That's why we use products and frameworks - so we don't have to. You can respectfully disagree with my argument, but the reality is that until better tooling exists and the application platform exposes the capabilities of OSGi, the enterprise is not going to use it. And I wish they could! I shall now take a retreat to write some code...:-) Kirk Knoernschild http://www.kirkk.com http://techdistrict.kirkk.com http://planet.kirkk.com twitter: pragkirk On Mar 26, 2009, at Mar 26, 1:04 AM, Rob Walker wrote: I added my 10c: http://techdistrict.kirkk.com/2009/03/25/osgi-discontent-no-migration-path/#comment-7129 When did developing sotfware and apps get reduced to mindless lego block assembly - where did all the real programmers go?

Re: Blog on OSGi
Rob, Curious - What application server do you use? Jetty embedded within Felix? I never suggested it wasn't possible to do (I know it's possible), only that it isn't feasible for most organizations to attempt. But if I've got my current generation of applications deployed on WAS, WebLogic, or JBoss, most organizations would look at me like I was crazy were I to suggest embedding Jetty within Felix.

Re: Blog on OSGi
The techniques you are using are the types of best practices and patterns that are lacking, and that are impeding more widespread adoption. How are you embedding Felix in your apps? How do you support JSP? That type of thing. Can you share the techniques you're using to deploy web apps to these app servers while still leveraging OSGi?

Re: Embedding Felix
I've reviewed that page. I was hoping for a simple JAR file that contained code similar to this that provided these functions. Something similar to the PAX Web stuff for embedding Jetty in OSGi, except the other way around. I suppose I can code it up myself, though I was hoping there was something reusable that I could pull in. Any other thoughts before I embark on a coding exercise?
