Filtering out (some) Sonar violations
Gents, if you take a look at [1], you will realize that we have a quite long path to reach a decent quality level of Cocoon 3's source code. At the moment, the most "bad" violations are related to a couple of rules that couldn't apply to Cocoon 3, for different reasons: 1. Using member variables in servlets [2] - Cocoon 3 uses the ServletService framework, so servlet's lifecycle is not managed in the usual way, by a Servlet container 2. Direct allocation of a specific implementation of xml interfaces [3]: NekoHtml does not provide a SAXParserFactory, only provides direct instantiation My proposal would be to open a issue to INFRA in order to ask for disabling these two rules: do you see any problem, with this? For my personal experience about Findbugs, PMD and Checkstyle, it is rather impossible to satisfy all the rules (thus bringing the number of violations to zero); however, I personally think that reducing the huge amount that we have at the moment would dramatically improve Cocoon 3's source code quality. Cheers.

Given that there may not be enough people and sponsorship for a Cocoon GT, what about some kind of virtual GT? I.e. a concentrated time of group web presence. We could still have presentations, Q&A, hackathon, maybe using audio channel such as Blink/Mumble/TeamSpeak... For me, the most valuable part would be a tutorial on getting up to speed on Cocoon development... with the minimum grounding in Maven/Wicket/Spring/Java servlet technologies required, and with plenty of opportunity to ask questions. A couple of simple "hello world" tutorials would be worth a lot. Regards, Lars -- Francesco Chicchiriccò Apache Cocoon Committer and PMC Member http://people.apache.org/~ilgrosso/

Re: "Springification" of C3 - proof of concept
Hi Igor!!! congrats for your committership and your dedication to this work!!! I really appreciate you shared your results with us! Just my *personal* POV: even if I'm NOT a SpringFramework fan (and I won't be :P) your work shall be included in a way or another in C3. Anyway I would prefer Spring doesn't play the main role: I mean, having 3rd parties integrations it more than fine - we already have indeed modules with 3rd parties integrations, like StringTemplate, JAX-RS, Optionals (Solr, JAXB) - but IMHO Cocoon *core* components should not be dependent by any framework, I wouldn't "force" C3 users learning Cocoon AND Spring as a starting point, or require Spring as knowledge base to get started with Cocoon. I think that should sound reasonable, WDYT? So, my suggestions, if you are happy to continue on contributing - and I really hope you are :) - is: * checkout the latest C3 code from /trunk; * understand how it is actually organized and check what has been already implemented (for sure you can help us on improving actual JAXB implementation, for example) * starting proposing and discussing modifications/additional components step by step, not sure everybody would agree on adding everything as a single big commit ;) Many thanks in advance, all the best!!!
