wow, this is all good to know! Thanks! I definitely consider myself junior 'java' developer even though i've been developing software since 1995. I'm loving java/jsf and tomee/tomcat right now. my app is running fine, but i'm always striving for perfection and performance, and that is why I made my way from mojarra to myfaces, glassfish to tomee/tomcat, and jsf-managed-beans to cdi-managed-beans, and just early this morning from APR to NIO connector. >> b) Lots of people forget to correctly close external resources (files, tcp >> connections, jdbc resources).
