Usually JSP is first translated to regular Java code and then compiled into a Java servlet. JSP Weaver eliminates the Java generation and compilation stage by interpreting the JSP files on-the-fly. This reduces the time taken to reload a JSP up to 50 times bringing it from seconds down to milliseconds.
We have launched the next milestone of the JSP interpreter JSP Weaver. This release brings you the long awaited JSP standard syntax support and includes several fixes. All the known limitations have been addressed we are getting ready to release the final version. Now JSP Weaver supports full JSP specification from 1.0 to 2.1. However we do not support Java 5 language changes like generics and enums in scriptlets at the moment.
