The weekend's server move broke various things here, including the permalinks and the RSS and Atom feeds. I think I've now created workarounds for most of the pieces that broke, Holler if you notice any remaining issues. However I'm at SD Best Practices in Boston for the next few days so I may not be able to fix things immediately.
The Apache Jakarta Project has released Commons JEXL 1.1. "Java Expression Language (JEXL) is an expression language engine which can be embedded in applications and frameworks. JEXL is inspired by Jakarta Velocity and the Expression Language defined in the JavaServer Pages Standard Tag Library version 1.1 (JSTL) and JavaServer Pages version 2.0 (JSP). While inspired by JSTL EL, it must be noted that JEXL is not a compatible implementation of EL as defined in JSTL 1.1 (JSR-052) or JSP 2.0 (JSR-152). For a compatible implementation of these specifications, see the Commons EL project."
